Then here is your chance to ask someone face to face! With around 2 months to go until the 2014 NovoPulp deadline passes, we wanted to give everyone a chance to raise their hand and ask the questions that the rest of us didn't. Even if you can't attend the Hangout live, please leave your questions so you can watch the video afterwards and still get the information you need. As the last HOA was aimed at the USA/Australian time-zones we have decided to make this Hangout more European friendly. The HOA will be on:SATURDAY 7th OF JUNE 2014 - 16:00 CET / 10:00 EDT Submission Status:We are still in need of more short stories for this year but in particular WE NEED ART.

NASA Goddard164,532On March 29, 2014, an X-class flare burst off the right side of the sun . . . and NASA was watching.Coordinating their observations, five NASA observatories and one ground-based telescope were able to see things in the flare they'd never seen before.  Numerous other NASA spacecraft provided additional data about what was happening on the sun during the event and what the effects were at Earth. Join us at 2:30 p.m. EDT on Thursday, May 8, 2014, as researchers describe how multiple missions worked together to explore the sun's surface and atmosphere, layer by layer, providing unprecedented images of the onset of a solar flare.  In addition to the colorful pictures of the sun that NASA will share, participants will explain how such research can help scientists better understand what sets off these large explosions on the sun. Perhaps, someday scientists may be able to predict their onset, forewarning of the radio blackouts they can cause near Earth – blackouts that can interfere with military, airplane and ship communications.Participants include: Adrian Daw: IRIS project scientist at NASA GoddardAlbert Shih: RHESSI scientist at NASA GoddardSabrina Savage: Hinode deputy project scientist at NASA MarshallLucia Kleint: Bay Area Environmental Research Institute Jeffrey Newmark: NASA HeadquartersNASA Hangout: All Eyes on the Sun2014-05-08 20:30:00652

The infinite multiverse hypothesis : Three physicists recently came together to debate the pros and cons of the hypothesis. The multiverse has been used as a Science Fiction trope for long, but the real physics and mathematics behind it exists. While we still need to have experimental data to support it, (one wonders how we can get that!) there are detractors and critics who say it may be a bias we have.

Many worlds : Quantum objects can be described using what's called a wavefunction, which can predict where it's going to be and how it's moving. But those predictions take the form of probabilities. The problem is that, as far as we know, there's no reason to have the wavefunction stop working. Yet measurements, in Levin's terminology, "break" the wavefunction. In the many-worlds interpretation, the wavefunction keeps working, but reality breaks, or at... more »

What is fire, electricity and magnetism - and how are they related? : At the atomic level these are very different from what we would assume at the macro level. In some ways they are all related, since it has to do with the movement of electrons and creation of charge. When you see a match light, what happens is energy is released. While most of it is in the Infrared spectrum (What we call heat), there is also some of it released in the visible spectrum (light). The release is due to the Oxygen bonding with the material you are burning. While the effect may be too small to be seen in a matchstick, there is electricity and magnetism at work here too. You can see the effect on the Sun. Our Sun (or any star) is a miasma of incandescent plasma.  One way to see this is to notice that the solar flares that leap from its surface are directed along the Sun’s (generally twisted up and spotty) magneticfi... more »

A Star is born : The simplest of questions often takes us down some fabulous paths. How is a star created? It seemed so basic - well dust gets together in a supernova, they coalesce and gravity pulls it all together. If there is enough matter, it gets superdense and fusion is sparked off. Well that is the basic understanding. Fascinating how simple concepts make it possible for us to live. Or is it as simple as we are making it out to be?

Protostars : The core of the cloud collapses faster than the outer parts, and the cloud begins to rotate faster and faster to conserve angular momentum. When the core reaches a temperature of about 2,000 degrees Kelvin, the molecules of hydrogen gas break apart into hydrogen atoms. Eventually the core reaches a temperature of 10,000 degrees Kelvin, and it begins to look like a star when fusion reactions begin. When it has collapsed to about 30... more »

A Star is born : The simplest of questions often takes us down some fabulous paths. How is a star created? It seemed so basic - well dust gets together in a supernova, they coalesce and gravity pulls it all together. If there is enough matter, it gets superdense and fusion is sparked off. Well that is the basic understanding. Fascinating how simple concepts make it possible for us to live. Or is it as simple as we are making it out to be?

Protostars : The core of the cloud collapses faster than the outer parts, and the cloud begins to rotate faster and faster to conserve angular momentum. When the core reaches a temperature of about 2,000 degrees Kelvin, the molecules of hydrogen gas break apart into hydrogen atoms. Eventually the core reaches a temperature of 10,000 degrees Kelvin, and it begins to look like a star when fusion reactions begin. When it has collapsed to about 30 times the size of our sun, it becomes a protostar.

Equiblirum : When the pressure and temperature in the core become great enough to sustain nuclear fusion, the outward pressure acts against the gravitational force. At this stage the core is about the size of our sun. The remaining dust envelope surrounding the star heats up and glows brightly in the infrared part of the spectrum. At this point the visible light from the new star cannot penetrate the envelope. Eventually, radiation pressure from the star blows away the envelope and the new star begins its evolution. The properties and lifetime of the new star depend on the amount of gas that remains trapped. A star like our sun has a lifetime of about 10 billion years and is just middle-aged, with another five billion years or so left.

Webb science : Groups of stars make up galaxies, while planets and ultimately life arise around stars.  Although stars have been the main topic of astronomy for thousands of years, we have begun to understand them in detail only in recent times through the advent of powerful telescopes and computers. A hundred years ago, scientists did not know that stars are powered by nuclear fusion, and 50 years ago they did not know that stars are continually forming in the Universe.  Researchers still do not know the details of how clouds of gas and dust collapse to form stars, or why most stars form in groups, or exactly how planetary systems form.

Powerhouse : At present, the only way we have of initiating hydrogen fusion is to use nuclear fission: the so-called "hydrogen" bomb uses the explosion of a plutonium bomb to (very briefly) ignite uncontrolled fusion of the hydrogen isotopes deuterium and tritium.  We cannot control fusion, although much research on the subject has been conducted over the past 40 years.  The Sun dodges these problems and fuses hydrogen via its sheer, overwhelming bulk.  The pressure at its center squeezes the gas there to fourteen times the density of lead.  The temperature is 15 million K°.

Animal doctors : No really. This is not a post about vets. This is about how animals self-medicate.... including parrots, dogs, cats, chimps, elephants and a host of other creatures. There is even a word for it. Zoopharmacognosy is derived from zoo which means animal, pharma  which stands for drug and gnosy, which means knowing. Next time you see your dog or cat eating grass, you know it's a part of their self-medication regime.

Neighbourhood pharmacy : Bears, deer, elk, and various carnivores, as well as great apes, are known to consume medicinal plants apparently to self-medicate. Some lizards are believed to respond to a bite by a venomous snake by eating a certain root to counter the venom. Baboons in Ethiopia eat the leaves of a plant to combat the flatworms that cause schistosomiasis.

Some lizards are believed to respond to a bite by a venomous snake by eating a certain root to counter the venom. Baboons in Ethiopia eat the leaves of a plant to combat the flatworms that cause schistosomiasis.

More widespread than one would assume : Birds, bees, lizards, elephants, and chimpanzees all share a survival trait: They self-medicate. These animals eat things that make them feel better, or prevent disease, or kill parasites like flatworms, bacteria, and viruses, or just to aid in digestion. Even creatures with brains the size of pinheads somehow know to ingest certain plants or use them in unusual ways when they need them. Anyone who has seen a dog eat grass during a walk has witnessed self-medication. The dog probably has an upset stomach or a parasite.

Cats may be eating grass for nutrients : In particular, a nutrient that grass provides for cats is folic acid. This is a vital precursor for your cat's ability to synthesize hemoglobin. Hemoglobin is what supplies your cat's organs with oxygen. We all know oxygen is pretty important.

Other examples : Red and green macaws, along with many animals, eat clay to aid digestion and kill bacteria. Pregnant lemurs in Madagascar nibble on tamarind and fig leaves and bark to aid in milk production, kill parasites, and increase the chances of a successful birth. Pregnant elephants in Kenya eat the leaves of some trees to induce delivery.

How does one determine if an animal is self-medicating? : Huffman established widely used criteria for judging when an animal is self-medicating. First, the plant eaten cannot be a regular part of the animal’s diet; it is used as medicine not food. Second, the plant must provide little or no nutritional value to the animal. Third, the plant must be consumed during those times of year—for example, the rainy season—when parasites are most likely to cause infections. Fourth, other animals in the group don’t participate. If the activity meets these standards, it is safe to assume the animal is self-medicating, Huffman says. Researchers have observed the practice in 25 regions involving 40 different plants.

Learned behavior? : The obvious question is how do the animals—some of them not noted for intelligence—learn to do this? How did sparrows and finches learn to collect nicotine-heavy cigarette butts to reduce mite infections in their nests? How do honey bees and wood ants know to line their nests with resin to combat bacteria? We don't know for sure, but there is a strong hypothesis.

Underwater drones : While there are still many challenges in having an autonomous Underwater Drone (UUV), the one in the video is opensource and is not much bigger than a small toaster.

"ROV stands for remotely operated vehicle" Stackpole said. "It's got a video camera on it, so you can see what it sees live. So I can put this in the water, fly it around and see what it sees."

We have all heard of the Bluefin-21 : The Bluefin was used to search for the blackbox of flight MH370. But the cost of prohibitive. The OpenROV sells for $849. It's not what everyone would call cheap, but you don't need a grant to get your hands on one. This affordability is how Stackpole and Lang hope to bring OpenROV to the masses, turning average people into Cousteau-like undersea adventurers. There are over 500 OpenROVs in use now around the globe. Even though the project is growing, Stackpole and Lang are sticking with their do-it-yourself ethos. The OpenROVs are an open-source project, meaning that anyone can hack them to create new features or uses for the devices. Lang and Stackpole sell the ROVs as kits, and customers put them together themselves.

The Hydroview : Controlled wirelessly (well, almost) via an iOS device or laptop, the HydroView submersible can dive 150 feet underwater at speeds of up to five knots while transmitting live feedback in full 1080p HD video, according to the Aquabotix press release. Although the company touts the bot as a "wireless iPad-controlled underwater vehicle," fact enthusiasts might be quick to point out the "wireless" connection is actually capable only between the iPad and the HydroView's "top-side box," which is then connected to the craft by a cable tether.

Autonomous UUVs : Truly autonomous UAVS and UUVs aren't quite ready for duty, but they are a big part of the Navy's plan for the future. "While admittedly futuristic in vision, one can conceive of scenarios where UUVs sense, track, identify, target and destroy an enemy--all autonomously--and tie in with the full net-centric battlespace."

Article extract: Back in November, drone enthusiasts built a modified quadcopter they call the "Heli-Carrier" that was modeled after the giant aircraft that SHIELD flies in the Marvel movies, and showed that one small drone could take off from another. In this new video, the homebuilt helicarrier stays aloft longer and launches miniature jets. It's all a drone enthusiast's dreams. Maybe next time out they can land a helicarrier on a helicarrier.

From Hackaday : If you’re not familiar, the Helicarrier is a fictional ship, the pride of S.H.I.E.L.D’s air force, or is it their navy. It’s a massive aircraft carrier with four huge repulsor engines built into it, borrowing tech from Stark Industries. The shear size of it is what makes it completely ridiculous, but at the same time, it’s also unbelievably awesome. Unfortunately, repulsor technology doesn’t seem to exist yet, so the FliteTest crew had to settle with a set of 8 brushless outrunner motors, with two per “engine”. The whole thing is almost 6′ long. It doesn’t handle that well (not surprising!) but they were able to launch another RC  plane off of it, mid-flight! Landing however… well you’ll have to watch the video.

Remember the 'Happy People Vertical Transporters in The Hitchhiker's Guide to the Galaxy ? : This is not really the same, but ThyssenKrupp is working on bringing ropeless elevators (Called 'Multi') which uses Maglev and can use multiple elevators in the same shaft, saves space and can go both up-down and sideways. It actually solves a lot of problems architects and designers are faced with. Read on to know more....

Why is this amazing? : The system has been compared to how modern underground train networks operate, with multiple elevator cabins running in a loop. As there are no cables the elevators can go forwards, backwards, up and down. The new elevator system could allow architects to create more innovative buildings.

Why is this amazing? : The system has been compared to how modern underground train networks operate, with multiple elevator cabins running in a loop. As there are no cables the elevators can go forwards, backwards, up and down. The new elevator system could allow architects to create more innovative buildings. "If you did a cross-section cut of a high-rise building, 40 to 60 percent is going to be consumed by elevator space." “This opens up vast possibilities in building design,” Patrick Bass, CEO of ThyssenKrupp North America, Inc., tells Popular Science. “We now can enable buildings as tall or as high as they can go, and we also now enable different shapes and configurations of the space within buildings.”

The issue with building height and rope weight : In addition, current elevators can only go so far in terms distance. Once an elevator gets longer than about 2,000 feet, the steel ropes are too heavy to lift the car. In the world’s tallest building, the 2,722-foot tall Burj Khalifa in Dubai, the ground elevators only go as high as 1,654 feet. To gain access to the top floor, people must transfer to a second set of elevators located at the top of the building.  (See earlier post on Ultrarope by Kone here - http://goo.gl/3xmxcZ )

Sideways for large buildings : Julian Olley, director at Ove Arup & Partners Ltd., is intrigued by the possibility. “It could be advantageous for people to go sideways, like in the new Apple building, where it’s not high, but it’s half a kilometer round — a huge donut building. Whether that would ever be commercially viable is up for interpretation.”

Coldest temperatures in the Universe - What happens at absolute zero? : If one looks at classical physics, an atom of Oxygen gas zooms around at approximately a thousand miles an hour. That is quite fast. The theory is that as we lower the temperature in a closed system, the gas would become a solid and closer to absolute zero, the atoms would stop moving altogether. The electrons orbiting the nucleus would stop dead in their tracks. Why? The energy levels would be zero. However, in reality this does not happen. Physics does not break down. And neither does chemistry. Why is this?

At absolute zero : If you were able to measure the individual molecules, you'd find something surprising: they're still vibrating and rotating, but just by a tiny, tiny amount — quantum uncertainty at work.

Coldest temperatures in the Universe - What happens at absolute zero? : If one looks at classical physics, an atom of Oxygen gas zooms around at approximately a thousand miles an hour.

The electrons orbiting the nucleus would stop dead in their tracks. Why? The energy levels would be zero. However, in reality this does not happen. Physics does not break down. And neither does chemistry. Why is this?

At absolute zero : If you were able to measure the individual molecules, you'd find something surprising: they're still vibrating and rotating, but just by a tiny, tiny amount — quantum uncertainty at work. To make things concrete, if you were to measure the rotation of a Carbon Dioxide molecule at absolute zero, for instance, you'd still find that the oxygen atoms are flying around the carbon at a few miles per hour — probably faster than you would have guessed.

How low can you go? : Getting down to absolute zero has essentially the identical problem with getting up to the speed of light. Getting to the speed of light requires an infinite amount of work, while getting down to absolute zero requires extracting an infinite amount of heat. Just to make it clear, both of these are impossible. Practically, the work needed to remove heat from a gas increases the colder you get, and an infinite amount of work would be needed to cool something to absolute zero. In quantum terms, you can blame Heisenberg's uncertainty principle, which says the more precisely we know a particle's speed, the less we know about its position, and vice versa. If you know your atoms are inside your experiment, there must be some uncertainty in their momentum keeping them above absolute zero – unless your experiment is the size of the whole universe.

Negative temperatures below absolute zero? : Familiar ideas of temperature work pretty well for most solids, liquids, and gases, and conform to the general expectation that it should always be greater than absolute zero. What are we to make of a recent claim by a group of German researchers that they have created an experimental system where negative (as in below absolute zero) temperatures can actually be observed and measured? Unfortunately 'negative temperature needs to be defined in terms of entropy... Entropy is a convenient mathematical construct which indicates that if heat is added to a system, the atoms become less ordered. In other words, they have more states, or shall we say, options, available to them. All a negative absolute temperature really means is that with the addition of heat, instead of becoming more random, atoms become more ordered. This can occur, for example, if the number of high energy spots available is limited, and therefore likely to be quickly filled.

Pink was for boys and blue was for girls : At least before the modern obsession of going the other way. It kind of proves that the color palette we expect for boys and girls is based on societal pressures. At least now we know better!

Roosevelt : Little Franklin Delano Roosevelt sits primly on a stool, his white skirt spread smoothly over his lap, his hands clasping a hat trimmed with a marabou feather. Shoulder-length hair and patent leather party shoes complete the ensemble. Social convention of 1884, when FDR was photographed at 30 months, dictated that boys wore dresses until age 6 or 7, also the time of their first haircut.

Pink was for boys and blue was for girls : At least before the modern obsession of going the other way. It kind of proves that the color palette we expect for boys and girls is based on societal pressures. At least now we know better!

Roosevelt : Little Franklin Delano Roosevelt sits primly on a stool, his white skirt spread smoothly over his lap, his hands clasping a hat trimmed with a marabou feather. Shoulder-length hair and patent leather party shoes complete the ensemble. Social convention of 1884, when FDR was photographed at 30 months, dictated that boys wore dresses until age 6 or 7, also the time of their first haircut. Franklin’s outfit was considered gender-neutral.

How conventions came to be : Why have young children’s clothing styles changed so dramatically? How did we end up with two “teams”—boys in blue and girls in pink? "It’s really a story of what happened to neutral clothing,” says Paoletti, who has explored the meaning of children’s clothing for 30 years. For centuries, she says, children wore dainty white dresses up to age 6. “What was once a matter of practicality—you dress your baby in white dresses and diapers; white cotton can be bleached—became a matter of ‘Oh my God, if I dress my baby in the wrong thing, they’ll grow up perverted,’ ” Paoletti says.

Pink for boys - since it is a stronger color : a June 1918 article from the trade publication Earnshaw's Infants' Department said, “The generally accepted rule is pink for the boys, and blue for the girls. The reason is that pink, being a more decided and stronger color, is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl.”

It all changed in 1985 : Prenatal testing was a big reason for the change. Expectant parents learned the sex of their unborn baby and then went shopping for “girl” or “boy” merchandise. (“The more you individualize clothing, the more you can sell,” Paoletti says.) The pink fad spread from sleepers and crib sheets to big-ticket items such as strollers, car seats and riding toys. Affluent parents could conceivably decorate for baby No. 1, a girl, and start all over when the next child was a boy.

Gendered roles : “One of the ways women thought that girls were kind of lured into subservient roles as women is through clothing,” says Paoletti. “ ‘If we dress our girls more like boys and less like frilly little girls . . . they are going to have more options and feel freer to be active.’ ”

Antibiotics are limited : Antibiotics have been used for three quarters of a century to treat bacterial infections. Evolution is real. And so bacteria have evolved resistance to the antibiotics we use to kill them. We then invented new antibiotics, in response the bacteria evolved again — and the cycle repeats. The problem is that we are already running out of new antibiotics, but bacteria won't run out of evolution.

Enter bacteriophages : It turns out that there is a living creature that kills bacteria — a virus called a bacteriophage. The name literally means 'bacteria eater'. In the 1920s, bacteriophages were used to treat bacterial infections in both the United States, and in Georgia in the Soviet Union. Nothing else worked - antibiotics had not yet been invented. Bacteriophages were developed and used in Georgia until the present day. But in the West they were abandoned  after the introduction of antibiotics. Antibiotics were cheap, easy to make, store and prescribe. On the other hand, bacteriophages had to be individually blended, on demand. Furthermore, antibiotics could attack a whole range of different bacteria, while bacteriophages would work only against very specific bacteria. If you wanted to kill a different bacterium, you needed to use a different bacteriophage.

Bacteria eaters : Your typical bacteriophage virus looks a bit like a moon lander - a tall skinny body on top of a bunch of spindly legs. The bacteriophage lands on a bacterium, legs down. The legs then bend and the body of the bacteriophage makes contact with the much larger body of the bacterium. The tail of the bacteriophage then penetrates into the bacterium and injects some of its genetic DNA. The bacteriophage DNA then forces the host bacterium to start making more bacteriophages — sometimes within 15 minutes. Bacteriophage viruses are so potent that they kill about half the bacteria on Earth every two days.

Guided missiles : Each type of bacteriophage has evolved to attack only a very limited range of bacteria. But this turns out to have advantages.

If you take an antibiotic to treat an ear infection, it will also accidentally kill many of the essential and friendly bacteria that live in your gut. Bacteriophage therapy will leave these friendly bacteria alone. Bacteriophages are more like a guided missile than a nuclear bomb.

Applications : Childhood fears aside, the technology being demonstrated here is fantastic, and lends itself to some very practical uses. The swappable head can be outfitted with a camera for performing visual inspections in dangerous areas, because the robot snake can maneuver around debris or obstacles without touching a single thing. Or you can toss a high-pressure water jet on the end, making this the ultimate remote control auger for dealing with clogs or dirt.

the Specs : The Series II - X125 system delivers a 6kg payload, arm bend of over 225 degrees and a highly flexible tip. The 2.2m arm has passed a series of extended operational tests and been designed for increased reliability and easy maintenance to reduce through life costs.

Lightning as a power source : Some of the few astonishing facts about lightning is that there are about 100 lightning flashes every second.... that's not all, the power released in a lightning strike is 5 billion joules on an average. But there are issues. One is how does one harness the power of lightning, which happens randomly. The other is how does one step down this intense power to be used by us? It is a fascinating thought, since this is energy for the taking. Harnessing and managing its collection, step down and storage are gigantic headaches. And we don't yet have the engineering to make it happen. Read on....

Out of reach : A single bolt of lightning contains 5 billion joules of energy, enough to power a household for a month. The energy of a thunderstorm equals that of an atom bomb. If we're already generating power from unexpected sources like ocean currents in our quest to wean ourselves of polluting- and limited- fossil fuels, why not pull electricity from the air, especially when everyone can see it lighting up the night sky?

Challenges : The logistical problems involved in making it work are significant. First of all, there's the basic fact that thunder storms are sporadic and lighting strikes random; considering that energy demands are steady, dependable energy sources are preferable. Second, it's not so easy to capture energy delivered in one enormous blast in a split second. It has to be stored and converted to an alternating current, without blowing out the collection system in a single large strike.

Newer research : According to researchers at the University of Arizona and University of Central Florida, high-power lasers can be used to redirect the flow of lightning. As a general rule, lightning follows the path of least resistance (impedance) to the ground. A big metal rod, with wires running into the ground, has much lower resistance than air (which has very high electrical resistance) — and so the lightning chooses the rod. High-power lasers also don’t like to travel through air — but, when they do, they strip away electrons, leaving a wake of highly conductive ionized plasma. Lightning loves travelling through plasma. But this is limited due to the 'blooming' effect of lasers and maintaining a beam. To create a long enough channel of plasma — from the ground to the top of a building — the researchers had to devise a new method of beaming high-power lasers through air. The technical name of this method is called “externally refuelled optical filaments

Southampton University experiments : But can we harness electricity from lighning? There are several reasons why the current answer is probably no — safety, for starters — but some lightning scientists in the UK demonstrated that someday, the answer could be maybe. Nokia approached Neil Palmer, who directs Southampton University’s Tony Davies High Voltage Laboratory, to research harnessing lightning to charge a phone. “We wanted to look at whether we could harvest enough power to charge a Lumia 925 after the energy had moved through the air." Palmer set up a transformer providing an alternating current, and 200,000 volts of electricity sparked across about a foot (300 mm) of empty space. The signal was stepped down in a second controlling transformer, and connected to the phone. It worked: the phone charged up, and nothing fried. The lack of damage to the phone was the biggest surprise. "The Lumia 925 still worked perfectly, and is still working as good as new," Palmer says.

This is not an oil rig : Quite the opposite actually. While it does generate power, what is pictured is an OTEC (ocean thermal energy conversion) facility. While it has been theorized for some time now, we are now seeing a few working facilities. It is still considered an emerging technology, but Japan and the Hawaii OTEC projects are now online and provide proof of concept.

New study brings hope : A new study predicts that large-scale power plants based on thermoelectric effects, such as small temperature differences in ocean water, could generate electricity at a lower cost than photovoltaic power plants. Liping Liu, Associate Professor at Rutgers University, envisions that thermoelectric power plants would look like giant barges sitting in the tropical ocean, where electricity is generated by heating cold, deep water with warm, shallow water heated by the sun.

Liping Liu, Associate Professor at Rutgers University, envisions that thermoelectric power plants would look like giant barges sitting in the tropical ocean, where electricity is generated by heating cold, deep water with warm, shallow water heated by the sun.

Lockheed Martin interested in China OTEC project : Lockheed has been testing the technology for several years at a site in Hawai’i in partnership with Makai Ocean Engineering, the Energy Department and the US Navy, however several obstacles kept the idea from growing into a full-scaled power plant, according to sources familiar with the testing program.

How it works : "Warm surface seawater is pumped through a heat exchanger, where the low-boiling-point fluid is vaporized," the EERE stated. "The expanding vapor turns the turbo-generator. Cold deep seawater – which is pumped through a second heat exchanger – then condenses the vapor back into a liquid that is then recycled through the system."

From Princeton Univ : OTEC uses the difference between cooler deep and warmer shallow waters to run a heat engine. As with any heat engine, greater efficiency and power comes from larger temperature differences. This temperature difference generally increases with decreasing latitude, i.e. near the equator, in the tropics. Historically, the main technical challenge of OTEC was to generate significant amounts of power efficiently from small temperature ratios. Modern designs allow performance approaching the theoretical maximum Carnot efficiency.

That said, these gals and guys applied for the right to work on the project (another 100 or so were rejected) and nearly all of them have day jobs at companies like Boeing, NASA, Yahoo!, Airbus, SpaceX, and Salesforce. They’re smart. And they’re organized.

Working groups : The team is split into working groups, based on their interests and skills, that cover various aspects of the massive project, including route planning, capsule design, and cost analysis. They work mostly over email, with weekly discussions of their progress. Hierarchy is minimal, but leaders have naturally emerged, says Ahlborn. And if a decision needs to be made, as CEO, he makes the call. A lot of the work is being done by 25 UCLA students. The school’s SUPRASTUDIO design and architecture program partnered with JumpStartFund, and now the students are working on all the design solutions the new transit system would require.

Route : The UCLA students working on potential routes imagine networks criss-crossing the country, as well as Europe and Asia. This is where things get fanciful: we’re at least 10 years away from a commercially viable Hyperloop, and the idea of a national network is hard to imagine. They tacked on the idea of a “Mini Hyperloop,” which would offer shorter routes into and around cities.

Progress : So JumpStartFund and the UCLA students have made good progress, but there’s a lot to figure out before anyone gets to tackle the really fun parts like testing, permitting, and construction. Ahlborn says the questions of how to build the low-pressure tube and the pylons that support it have mostly been solved, and creating the capsules shouldn’t be too tricky. The hard part is moving the capsules within the tube, and seeing how fast they can go. To eliminate friction in the tube, Musk proposed using a compressor to create a pocket of air under the capsule. That’s the cheapest approach, Ahlborn says, but it has its drawbacks. His team is looking at the possibility of using magnetic levitation and other alternatives. “We want to find the best possible way to make this work.”

Promising : The TWEETHER project will result in a powerful and compact transmission hub, based on a novel travelling wave tube power amplifier and an advanced chipset in a compact terminal, with performance far outweighing any other technology. After three years of design and development, the system will be tested in a real operating environment.

New idea : Professor Paoloni said the answer was the exploitation of unused portions of the spectrum but at higher frequencies. The recent outstanding advancements in the field of vacuum electron devices and solid state electronics using millimetre wave frequencies opens the route for the breakthrough in wireless high speed data communications.

Well the post is self-explanatory and Carrie is really awesome.

Well,  I'm doing this.

Why?  Because its become pretty clear that I have to do this.  I have to get better.  I have to get my life back.  Going to the pool, it helps.  And I need to go a few times a week because it is helping.  But I'm going to run out money to do it soon.

I am asking for support to continue to go to the pool, to start a walking regimen at home, where its safe, and hopefully over the next year build the stamina and lessen the pain.  

If you can't donate, can you share my story around?  It would be really awesome if I could start the New Year on a positive note for once.  It isn't easy asking this, but I have nothing left to lose.

Thanks.

Hi! My Name is Carrie, or Carrot as I've become affectionately referred to.  I have fibromyalgia, multi-level disc degeneration, spinal stenosis and peripheral neuropathy.  I have been unable to work for nearly 4 years and my life has become very limited.  I am in constant pain and it dictates everything I do from sleep to a social life.

Recently I found aquatic therapy after several repeated failures with traditional physical therapy.  Twice a week I go to a heated pool and am able to slowly increase the range of motion, and it doesn't hurt.  It actually feels good.  The tingling in my fingers and toes subsides and I feel more positive.

It works so much better than taking pain medication and I feel better about myself.

My doctor recommends that I use the pool as often as possible.  Daily if I can.  It is also recommended that I start a walking regimen to slowly increase my stamina above ground.  Its also about developing the habit of motion and retraining my body to respond better to motion and stop resisting it.  

The problem is that it is expensive.  I have managed to work out a reduced rate for a yearly membership at the pool that I do my aquatic therapy which would include all their locations (very convenient).  This is awesome and comparable to the YMCA but with less foot traffic. 

The other problem is that my health insurance has limited therapy allowances, so at some point I will be unable to receive aquatic physical therapy unless I pay for it myself.  If I have a yearly membership, I can at least apply my knowledge to the remainder of the year and keep moving.

Walking is another major issue.  I have an intense cold sensitivity.  In the winter I will break out into welts and get asthmatic from the air, so just walking outside is inadvisable.  Getting a treadmill really is the way to go to ensure that I am doing some dedicated walking every day.  I can schedule time to get out of the house and into the pool at least 4x a week.  I can't guarantee 7x for walking.

Therefore, my estimate would cover my year of expenses for a membership, a treadmill (nothing fancy), and gas money or pool equipment (they have these neat floating bar bells and stuff) I would require. 

I am not exaggerating when I say that these things are making my life not only better, but for the first time in a long while I feel like I might be able to get some control back.  I look forward to going to the pool each time.  I feel much more alive afterward, I walk better, I have less balance problems and less intense pain because of the warm water.  Walking is going to be hard, but I know that I need to work on this if I'm ever going to get my life back.  I just need your help to get me there...___Well the post is self-explanatory and Carrie is really awesome.

Nanopore battery : Imagine a battery which is made up of nanotube electrodes. And then imagine a billion of thesese nanotubes 'grown' on a substrate to create a battery which can charge in 12 minutes. Thousands of times. Imagine the size of the battery with billions of electrodes is the size of a postage stamp cumulatively. Can you imagine your cellphone having this kind of charging ability. Researchers at University of Maryland are testing just this kind of battery.

Small is beautiful : Many millions of these nanopores can be crammed into one larger battery the size of a postage stamp. One of the reasons the researchers think this unit is so successful is because each nanopore is shaped just like the others, which allows them to pack the tiny thin batteries together efficiently. Modeling shows that the unique design of the nanopore battery is responsible for its success.... more »

Small is beautiful : Many millions of these nanopores can be crammed into one larger battery the size of a postage stamp. One of the reasons the researchers think this unit is so successful is because each nanopore is shaped just like the others, which allows them to pack the tiny thin batteries together efficiently. Modeling shows that the unique design of the nanopore battery is responsible for its success. The space inside the holes is so small that the space they take up, all added together, would be no more than a grain of sand.

The Tech : Co-author Eleanor Gillette said: 'A nanopore is a tiny hole, 80,000 times smaller than a human hair, that's made in a sheet of ceramic material.' A battery composed of an array of nanobatteries connected in parallel, each composed of an anode, a cathode and a liquid electrolyte confined within the nanopores of anodic aluminium oxide, as an all-in-one nanosize device.Each nanoelectrode includes an outer ruthenium nanotube current collector and an inner nanotube of vanadium pentoxide storage material. These together form a symmetric full nanopore storage cell with anode and cathode separated by an electrolyte region.

What is possible? : Sky is the limit. But this may actually make electric cars and aircraft commercially viable, and even cheaper than gas. While the current version is intended mostly as a proof-of-concept model, the scientists have determined improvements that could be made to the second version, allowing it to have 10 times the energy density. They're also looking at methods of industrial-scale production, so that the batteries could ultimately be produced commercially.

The Walls can Talk : There was an earlier story about researchers at MIT who extracted audio from vibrations in a potato chip bag, but now scientists have been able to reconstruct audio from videos by using vibrations observed in lightweight objects. While there are more sophisticated methods available, the researchers used a image-matching technique to measure the vibrations. Read on to know more....

How it's done : The technique is based on the fact that sound waves are mechanical waves that cause air to vibrate when traveling. That vibration through air can cause vibration of objects located in its traveling path, especially if the objects are lightweight, thin, and flexible, such as a piece of paper. The vibrations, although usually with small amplitudes, can be detected and analyzed algorithmically, and audio reconstructed based on those calculations.

Applications : Because light can travel through air considerably farther than sound and can pass through glass, they anticipate that the technique may find applications such as the passive detection of conversations inside of a building from a far distance.

The Technology : The authors used a subset-based image-correlation approach to detect the motions of points on the surface of an object, capturing target images with a high-speed camera and applying the Gauss-Newton algorithm and a few other measures to achieve very fast and highly accurate image matching. Because the detected vibrations are directly related to sound waves, a simple model was used to reconstruct the original audio information of the sound waves.

Quantum whirlpools : Trying to understand the superfluid state of helium, have led researchers to finally create quantum whirlpools as observed earlier. Dr. Elena Ostrovskaya from ANU (Australian National Univ.) has said it has been a challenge to control these vortices (circulating currents of polaritons) before. "The vortices have previously only appeared randomly, and always in pairs that swirl in opposite directions," said Dr. Robert Dall, who led the experimental part of the project. "However, by using a spiral mask to structure our laser, we create a chiral system that prefers one flow direction. Therefore we can create a single, stable vortex at will."

Quantum whirlpools : Trying to understand the superfluid state of helium, have led researchers to finally create quantum whirlpools as observed earlier.

"The vortices have previously only appeared randomly, and always in pairs that swirl in opposite directions," said Dr. Robert Dall, who led the experimental part of the project. "However, by using a spiral mask to structure our laser, we create a chiral system that prefers one flow direction. Therefore we can create a single, stable vortex at will." These vortices are an example of quantum fluid behavior in which the polaritons coalesce into a rare state of matter known as a Bose-Einstein condensate.

Polaritons : Polaritons are hybrid particles that have properties of both matter and light. The ability to control polariton flows in this way could aid the development of completely novel technology to link conventional electronics with new laser and fibre-based technologies. Polaritons form in semiconductors when laser light interacts with electrons and holes (positively charged vacancies) so strongly that it is no longer possible to distinguish light from matter.

Bose-Einstein condensates : “The beauty of a Bose-Einstein condensate is that it is similar to a laser but made of matter,” Dr Davis said. “It is a collection of atoms that are perfectly coherent and have the potential to be used in ultra-sensitive measurement devices.” BECs were first predicted in the 1920s by Einstein.

Spiral masks : The team created the spiral beam by putting their laser through a piece of brass with a spiral pattern of holes in it. This was directed into a semiconductor microcavity, a tiny wafer of aluminium gallium arsenide, a material used in LEDs, sandwiched between two reflectors. “By using a spiral mask to structure our laser, we create a chiral system that prefers one flow direction. Therefore we can create a single, stable vortex at will.”

Affordable Housing : I've been working on a research paper for the past two weeks, and away from Google plus for the most of this time. Its been quite interesting from the viewpoint of what has been imagined and how people view this topic. The funny thing is if done right, it costs a small fraction of the market price.

We are running out of space : We really are. But the way forward is sustainable, creative ways to do things which can get us good quality housing at low prices for everyone. Cities are now the powerhouses of the future. And most countries count on them to increase their GDP. It is estimated that over 60% of future economic growth is linked to cities.

Affordable Housing : I've been working on a research paper for the past two weeks, and away from Google plus for the most of this time. Its been quite interesting from the viewpoint of what has been imagined and how people view this topic. The funny thing is if done right, it costs a small fraction of the market price.

We are running out of space : We really are. But the way forward is sustainable, creative ways to do things which can get us good quality housing at low prices for everyone. Cities are now the powerhouses of the future. And most countries count on them to increase their GDP. It is estimated that over 60% of future economic growth is linked to cities.

What makes sense : We need to do better as far as recycling materials, creating housing in sea and land and keeping them sustainable. Zero carbon footprint houses are not only possible, but critical. From estimates from over 20 countries, only 20-30% of the cost of a house is related to construction. The rest is related to land, taxes, government delays, issues with planning and project management.

Container houses / floating residences : The world is changing. Much quicker than many of us expected. Today many houses are made from transport containers and floating construction has been attempted in a number of countries. We need some way of making this available to the poorest of the poor as well as the richest of the rich so that its not just the province of a small elite.

Affordable does not mean shanties : If it is done right, affordable housing has access to public utilities, water, electricity, schools and healthcare and reduces commutes to work. Spaces are smaller, more sustainable and green. It recycles, reuses and is an integral part of a city.

Economic schemes : Many countries have tried to address the problem using rental schemes, part ownership, private-public partnership, zoning, transport corridors and Real Estate Investment Trusts. Some have been very successful. The stories are not always told.

What is fire, electricity and magnetism - and how are they related? : At the atomic level these are very different from what we would assume at the macro level. In some ways they are all related, since it has to do with the movement of electrons and creation of charge. When you see a match light, what happens is energy is released. While most of it is in the Infrared spectrum (What we call heat), there is also some of it released in the visible spectrum (light). The release is due to the Oxygen bonding with the material you are burning. While the effect may be too small to be seen in a matchstick, there is electricity and magnetism at work here too. You can see the effect on the Sun. Our Sun (or any star) is a miasma of incandescent plasma.  One way to see this is to notice that the solar flares that leap from its surface are directed along the Sun’s (generally twisted up and spotty) magneticfi... more »

You can see the effect on the Sun. Our Sun (or any star) is a miasma of incandescent plasma.  One way to see this is to notice that the solar flares that leap from its surface are directed along the Sun’s (generally twisted up and spotty) magnetic fields. So what is this all about?

Electricity : The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton, and the number of electrons in an atom is usually equal to the number of protons. When the balancing force between protons and electrons is upset by an outside force, an atom may gain or lose an electron. When electrons are "lost" from an atom, the free movement of these electrons constitutes an electric current.

Different colors in flames : Electrons on atoms have different amounts of energy proportional to the distance of their orbital from the nucleus. Electrons (which are negative) close to the positive nucleus have lower potential energy; those in "higher" energy levels farther away have more energy. In order for an e- to "jump" from a lower level to a higher one it must absorb energy, often in the form of light. Conversely when an e- "falls" from a higher level to a lower one, it gives off energy, again in the form of a photon of light.

Magnetism : All materials experience magnetism, some more strongly than others. Both electric and magnetic interactions are elements of a single phenomenon called electromagnetism. There are four fundamental forces: the strong force, the weak force, gravitation and the electromagnetic force. The field of electromagnetism deals with how electrically charged particles interact with each other and with magnetic fields.

Electrons : The picture you often see of electrons as small objects circling a nucleus in well defined "orbits" is actually quite wrong. As we now understand it, the electrons aren't really at any one place at any time at all. Instead they exist as a sort of cloud. The cloud can compress to a very small space briefly if you probe it in the right way, but before that it really acts like a spread-out cloud. For example, the electron in a hydrogen atom likes to occupy a spherical volume surrounding the proton. If you think of the proton as the size of a grain of salt, then the electron cloud would have about a ten foot radius. If you probe, you'll probably find the electron somewhere in that region.

What is plasma : The big difference between regular gas and plasma is that in a plasma a fair fraction of the atoms are ionized.  That is, the gas is so hot, and the atoms are slamming around so hard, that some of the electrons are given enough energy to (temporarily) escape their host atoms.  The most important effect of this is that a plasma gains some electrical properties that a non-ionized gas doesn’t have; it becomes conductive and it responds to electrical and magnetic fields.  In fact, this is a great test for whether or not something is a plasma.

Canada, Malawi and Philippines have strongly objected to testing using engineering bacteria to fix CO2. Even testing in controlled experiments has been stalled. In some ways, we are running out of time.

Controversial : Even research related to geoengineering has become the topic for passionate debate, pitting curious scientists against a chorus of intense skepticism.

Too dangerous to consider : Many had hoped the IPCC's latest report might open the door to more research into geoengineering, allowing scientists to get a better sense of its risks and benefits — but in the group's recommendations to world leaders, there wasn't a single mention of the process, even as it heaped praise on alternative processes like carbon dioxide removal, which would use chemicals or bacteria to pull CO2 directly from the atmosphere.

Bacteria fix CO2 : Biological reactions are good at forming carbon-carbon bonds, using carbon dioxide as a raw material for reactions powered by sunlight. It's called photosynthesis, and cyanobacteria, also known as "blue-green algae," have been doing it for more than 3 billion years. The researchers identified enzymes from online databases that carried out the reactions they were looking for, and then introduced the DNA for these enzymes into the cells. Working a step at a time, they built up a three-step pathway that allows the cyanobacteria to convert carbon dioxide into 2,3 butanediol, a chemical that can be used to make paint, solvents, plastics and fuels.

Microbes in the sea : Based on his findings, Dr Jiao and his colleagues propose that aerobic anoxygenic photoheterotrophic bacteria (AAPB), and possibly other, similar microbes, have a predominant role in pumping carbon into a pool of compounds that cannot be turned back into carbon dioxide by living creatures, thereby building up a large reservoir that keeps carbon out of the atmosphere. If that idea is confirmed, it will need to be incorporated into the computer models used to understand the Earth's carbon cycle and its effect on the climate. But it also raises a more radical thought. The microbial carbon pump could provide a novel way to extract CO2 from the atmosphere, should that ever be deemed necessary to combat climate change.

Deep concerns : Scientists have created a self-replicating synthetic life in 2010, and a few hours later, a United Nations science advisory body meeting here urged countries to take a strong precautionary approach to avoid release of such entities into the environment. Acting as the world’s guardian on biodiversity, it also expressed deep concern about the potential impacts of geoengineering schemes to combat climate change on the Earth’s ecosystems. The same advisory body made a similar recommendation in 2008, that led to a de facto global ban on a form of geoengineering called ocean fertilisation, an experimental method of reducing carbon dioxide in the atmosphere to combat global warming.

Now scientists are looking at the quantum mechanical nature of the world and how at the cellular and even macro level, some creatures are able to take advantage of the weirdness.....

Quantum Hanky-Panky : Discoveries in recent years suggest that nature knows a few tricks that physicists don't: coherent quantum processes may well be ubiquitous in the natural world. Known or suspected examples range from the ability of birds to navigate using Earth's magnetic field to the inner workings of photosynthesis — the process by which plants and bacteria turn sunlight, carbon dioxide and water into organic matter, and arguably the most important biochemical reaction on Earth. Biology has a knack for using what works, says Seth Lloyd, a physicist at the Massachusetts Institute of Technology in Cambridge. And if that means "quantum hanky-panky", he says, "then quantum hanky-panky it is".

The avian magnetic sensor : The avian magnetic sensor is known to be activated by light striking the bird's retina. Researchers' current best guess at a mechanism is that the energy deposited by each incoming photon creates a pair of free radicals - highly reactive molecules, each with an unpaired electron. Each of these unpaired electrons has an intrinsic angular momentum, or spin, that can be reoriented by a magnetic field. As the radicals separate, the unpaired electron on one is primarily influenced by the magnetism of a nearby atomic nucleus, whereas the unpaired electron on the other is further away from the nucleus, and feels only Earth's magnetic field. The difference in the fields shifts the radical pair between two quantum states with differing chemical reactivity.

Schrödinger suspected as much : From smell to navigation, it seems that some of the hardest problems in biology could be solved with the insights from theoretical physics. The physicist Erwin Schrödinger wrote a book in the 1940s called “What is Life?” in which he speculated on the role of quantum mechanics on the life sciences. Almost 70 years later, both quantum mechanics and biology have moved on a long way. But until now, no one had imagined that the natural world has anything to teach us about the quantum world.

Cities : Cities by themselves are neither good nor bad. But we are tied to them and all indicators are that they will be the engine of growth in our world going forward (as per the latest report from the World Bank). In some ways, cities can be personal, in other ways, they promote individualism. I've seen a common thread about cities, which I wanted to share.

Cities getting bigger : It’s the age of the city. Today more than half the world’s population can be found in cities, and megacities—those with populations of 10 million or more—are on the rise. The world’s largest megacity, Tokyo-Yokohama, joins two cities and multiple Japanese prefectures to cover 5,200 square miles, and it houses a population of some 37.5 million individuals.

Cities getting bigger : It’s the age of the city. Today more than half the world’s population can be found in cities, and megacities—those with populations of 10 million or more—are on the rise. The world’s largest megacity, Tokyo-Yokohama, joins two cities and multiple Japanese prefectures to cover 5,200 square miles, and it houses a population of some 37.5 million individuals.

Source and Solution : Cities are poised to tackle the problems of climate change because they have economies of scale that promote efficiency, as well as research centers, grassroots movements and opportunities for invention and innovation, Romero Lankao notes. “It’s like every human being—we have good and bad, and cities are the same.” sheer size can’t protect megacities from direct impacts such as rising temperatures and extreme events like hurricanes and droughts. Already warmer than the countryside because of the urban heat island effect, cities in tropical and sub-tropical areas—such as Mumbai, Bangkok and Lagos—could soon become too hot to handle, especially for those who cannot afford air conditioning.

Metrosapiens : Some advantages - Demand-side benefits are important, because those strategies are not talked about very much. When we hear about national energy policy, it's often about increasing efficiency of devices or supply of energy. But people that live in New York City, for example, drive less because they don't have cars. This is something that David Owen talks about in the book Green Metropolis. He calls it "embodied efficiency". The vertical living of New York City actually has this embodied efficiency that makes energy use in our daily lives less.

An example of Boston : _With the specter of rising sea levels threatening many metropolises worldwide, cities are starting to rethink what their future might look like. And in Boston, that future might look a little bit like Venice, canals and all. A nonprofit research group, the Urban Land Institute (ULI), recently released a report which outlines Boston's options for dealing with rising waters. The sea level in Boston is currently rising at a rate of 0.11 inches per year. That may not seem like much, but eventually it could cause major, costly problems for the city.

Searching for answers in the bottom of a Whisky glass : The answer is related to fluid dynamics. This was discovered by Howard Stone, an engineer at Princeton University. Read on more to know about the Marangoni effect and how it is related to this pic...

Why : Stone initially suspected that something called the coffee ring effect might be at play: When coffee dries, particles are pulled to the edge of where the liquid makes contact with the cup, creating ring-like patterns as the water evaporates. Similarly, the differing evaporation tendencies of alcohol and water can create interesting patterns.

Similarly, the differing evaporation tendencies of alcohol and water can create interesting patterns.

The Marangoni effect : First described by 19th-century physicist Carlo Marangoni; alcohol and water have different surface tensions—that’s the degree of attraction liquid molecules have to other surfaces (in this case a cup or a glass). Alcohol has a lower surface tension than water, and alcohol evaporation drives the surface tension up and pushes more liquid away from areas of high alcohol concentration. The Marangoni number, a dimensionless value, can be used to characterize the relative effects of surface tension and viscous forces.

Practical Applications : Based on this work, the lab team has a hypothesis: “Very small amounts of the additives that come from how whisky is made contribute to the kinds of patterns you actually see,” says Stone. Different additives or variations in the manufacturing process might possibly produce different patterns. The research has some practical implications. Better understanding of these types of fluid flows could prove useful in a lot of industrial situations that involve liquids, particularly liquids that contain particles of sediment or other material, such as printing inks. In the meantime, Button hopes his images raise questions in the minds of viewers that may give them some interesting conversation starters at cocktail parties. “The science behind the imagery provides that extra added layer of thought and complexity,” he says.

The Sundew and English Ivy : The tentacles and their adhesive properties may be nature's design for catching insects, but Zhang's research team hopes that one day this same adhesive can help attach a replacement hip or an artificial knee without fear that the body will reject it.Post-doctoral researcher Scott Lenaghan explained that the idea behind this research at the Nano Bio-systems and Bio-mimetics Lab is to learn from biological principles and apply engineering along the way to develop an end product that uses these compounds and principles to advance technology.

Organic biomaterials : The lab's goal is to study biological material on the nanoscale--a million times smaller than a grain of sand--in hopes of mimicking what nature has done for millions of years and applying it to daily life. In medical replacement operations, "you need something cells can recognize and attach to," Lenaghan said. With the sundew, the researchers may have found just that, as the nanoparticles in its adhesive are easily recognized by human cells.

Au Naturel : Sundew and English ivy research in Zhang's lab are a part of a growing field of "next generation" materials that have a broad interdisciplinary impact. The hope is to replace the many synthetic products we use daily with naturally occurring substances.

Not path-breaking, but kind of cool : Saw the Switchblade-Pro tricopter featured on Popsci's '100 Greatest Innovations of the Year' list.  Well, I had to watch the video. The features are kind of cool, and it is collapsible. I did like the way it has a hover mode and handfree landing mode. See for yourself..

Article Extract: The three-rotor SwitchBlade, a small, collapsible drone that's already raised its target on Kickstarter, is designed to compete with radially symmetric quadrotors in the realms of search and rescue, infrastructure inspection, aerial photography, research, and (of course) recreational flight. According to creators Vision Aerial, the tricopter has better balance while flying forward compared with a quadcopter; it's also easier to determine the orientation of an asymmetrical drone while in flight.

Why Nanomaterials are fascinating (Or how a dog becomes a cat, becomes a hummingbird) : Well, any material can be a Nanomaterial. A Nanomaterial is purely something reduced to a size of 1 to 100 nms. So why the fuss? For one, unlike macro materials, Nanomaterials can be two dimensional. As we get smaller and smaller, they exhibit properties which confound us.  One must remember though, these are not chemically changed. All that is done is the size of the particles is made smaller and smaller.

In Nanotechnology, what is important about materials is NOT really what they are made of, but how small they are. This is different than every other materials age in human history.

In Nanotechnology, what is important about materials is NOT really what they are made of, but how small they are. This is different than every other materials age in human history.

Magnetism example : Atoms can have magnetic moments... Why is this? Due to the spin of unpaired electrons. A magnetic moment aligns with an external field. Let's take the example of CoCr (Cobalt Chrome Alloy). At the macro size, it displays no magnetism. This is because when at the macrosize, domains cancel each other out. These are called 'Bulk Ferromagnets' and can be electromagnets. So these sizes do not get highly magnetized and can be called permanent magnets (if enough of the domains align in one direction). Let's say these behave like Dogs..

As you go smaller, from 20nm grain size to 80 nm grain size, The magnetism in this powder will depend on volume. It is harder to magnetize these particles, but when these are magnetized, they resist going back to their original state. These are single domain magnets and once magnetized, they stay that way; though they are easy to magnetize and demagnetize. Let's say these behave like Cats....

When you go down to even smaller size, the ferromagnets are smaller than 20 nm in size, they are very, very small, not much bigger than molecules. They are easier to magnetize and flip. So easy to magnetize and flip, that this is a property used in MRI tests. Superparamagnets have fluctuating magnetic moments with no applied field, but with applied field become magnetized easily. These are called superparamagnets.  Let's say these behave like hummingbirds.

Nano scale : While speaking to some people, I realized that 'nano' as a scale is not really understood very well. It is often thought to be small. Even very small. But Nano size is very definite. It is like mixing up Kilometers and meters. Nano means 10^-9. That means a nanometer is a billionth of a meter. A typical sheet of newspaper would be 100,000 nanometers thick. Its a very precise measurement. Your typical fingernail grows at one nanometer per second.

Nanotechnology : When scientists worked with very small objects (of the size of 1 to 100 nanometers), they found some strange properties displayed by these materials. Some of them were magnetic, displayed strange optical properties and had even stranger electrical properties. These are now studied as Nanoelectronics, Nanophotonics, Nanomagnetics and the like.

The definition : Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.

Not as straightforward as one would expect :     Phenomena at the nanometer scale are likely to be a completely new world. Properties of matter at nanoscale may not be as predictable as those observed at larger scales. Important changes in behavior are caused not only by continuous modification of characteristics with diminishing size, but also by the emergence of totally new phenomena such as quantum confinement, a typical example of which is that the color of light emitting from semiconductor nanoparticles depends on their sizes. Designed and controlled fabrication and integration of nanomaterials and nanodevices is likely to be revolutionary for science and technology.

Are you an INTJ? You probably "are most comfortable working alone and tend to be less sociable than other types. Nevertheless, INTJs are prepared to lead if no one else seems up to the task, or if they see a major weakness in the current leadership. They tend to be pragmatic, logical, and creative."

versus

Are you an Aries? You're probably “the leaders of the pack, first in line to get things going. Whether or not everything gets done is another question altogether, for an Aries prefers to initiate rather than to complete.”

So what’s the difference, really?

TL;DR : Not much.
The long answer : Not much. :-)

Or, to be more precise, and a touch verbose – the comparison works better with, say, a Buzzfeed quiz.
As a brief background - The Myers–Briggs Type Indicator (MBTI) assessment is a psychometric questionnaire designed to measure psychological preferences in how people perceive the world and make decisions. These preferences were extrapolated by Katharine Cook Briggs and Isabel Briggs Myers from the typological theories proposed by Carl Gustav Jung. Jung theorized that there are four principal psychological functions by which we experience the world: sensation, intuition, feeling, and thinking. One of these four functions is dominant most of the time – Wiki

MBTI is a particular darling of the corporate world. According to a recent Forbes article, “Myers-Briggs Type Indicator (MBTI) assessments are extremely popular, as well as profitable for both the publisher and the many certified consultants who use them. In fact, they are so popular as to be nearly ubiquitous in corporations and large organizations, including 89 of Fortune 100 companies.” But how well does it work? Does it work at all? And is it used in a way that would be least detrimental?

I found myself in agreement with most of the points made in a  Skeptoid article – the genesis and intrinsic values of the MBTI and pop tools like zodiac signs or Buzzfeed quizzes  are not dissimilar. The article is quite interesting, and in my view, fairly balanced. As a training consultant, I’ve seen the value that tools like MBTI (and other psychometric assessments) can provide – they make great introspection and perception start-points; and often provide a framework to discuss group dynamics and to help evolve solutions. I have also seen the farcical side of using them – the lazy, unscientific short-cuts they provide for the indolent or incompetent, and the rather sad way in which they replace critical and original thinking.

The tool has its fair share of critics – unbiased and otherwise. As an agnostic about the value and context of anecdotal or experiential systems, I can see its worth;  but I find myself getting annoyed at the somewhat cultish adherence to its “findings”, or applications, or indeed the lack of healthy skepticism amongst practitioners and more importantly, buyers.

I also find amusing the way proponents of these tools react when you point out the (many) similarities to the zodiac-sign classifications; or Cosmo quizzes. Or point to the Forer Effect ( also called the Barnum effect after P. T. Barnum's observation that ‘we've got something for everyone’ is the observation that individuals will give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically for them, but are in fact vague and general enough to apply to a wide range of people – Wiki) Is it only because they come dressed in a patina of “science”? Or are they just a fad, waiting to be replaced by the next one? Or, as is always the case…… follow the money? According to a Forbes article – “2 million people a year (are) using an assessment tool that generates approximately $20 million in fees for its publishers”. Food for thought, for sure, I would've said.

The CPP website, btw, (the company that is the provider / publisher of the MBTI instrument) has this to say : It’s very common—especially on the Internet—to hear the MBTI® assessment referred to as the Myers-Briggs® personality test, the MBTI test, or simply the “personality test.” However, here at CPP, Inc., we never refer to the MBTI assessment that way. Personality tests may exist, but the MBTI assessment is not one of them. Here’s why…

So far, so logical. And then they go on to add –
By definition, a test is “a series of questions, problems, or physical responses designed to determine knowledge, intelligence, or ability,” implying that there are “right” and “wrong” answers. It’s true that the Myers-Briggs Type Indicator® assessment contains a series of questions, but that’s where the similarities to a personality test end. Unlike personality tests, the MBTI assessment doesn’t determine knowledge, intelligence, or ability. Instead, it measures four pairs of opposing preferences, which are inborn and value-neutral, to form a person’s four-letter type. No type is better or worse than any other—they are just different.

That explains quite a bit ;-)
I think this would be a good time to add that I am emphatically not certified in MBTI assessments. 

So, hello, Ms. Gemini, Mr. ISTJ, Ms. Flower-Child.....

Peanut butter diamonds : We all probably know that diamonds were formed by carbon under high temperatures and pressures. Since all organic materials have carbon, researchers are playing with such materials. Diamonds are often used in manufacturing and have many industrial applications.

Carbon : In his lab at the Bayerisches Geoinstitut in Germany, Dan Frost is trying to simulate conditions found in the Earth’s lower mantle. More than 1,800 miles below the surface, the lower mantle experiences temperatures nearing 4,000 degrees Fahrenheit and pressures that are 1.3 million times higher than the air we breathe. According to David Robson at BBC Future, in trying to simulate those scorching underground environments, Frost has stumbled upon some innovative ways to manufacture diamonds. Beneath their sparkles, diamonds are composed of simple carbon atoms arranged into a crystal.

From thin air : Frost's research started with a hypothesis that in ancient times, rocks could have pulled carbon dioxide from the oceans. Then, as the rocks were drawn down into the mantle, high pressures force the CO2 to leave the rocks. Once the CO2 was free, iron in the mantle stripped it of its oxygen. That left just the naked carbon, which was squished into diamond by the high heat and temperatures. That was the hypothesis anyway, "[a]nd that is exactly what Frost found when he recreated the process using his presses – essentially forging a diamond from thin air," writes Robson.

Peanut butter diamonds are slow : Because all foodstuffs (and for that matter, all living things) contain carbon, the researchers have successfully made diamonds out of everyone's favorite sandwich ingredient: peanut butter. However, the hydrogen that’s bonded to the carbon in peanut butter apparently does make the process messier. And even under the best circumstances, the transformation is slow. “If we wanted a two-or-three-millimetre diamond, we would need to leave it for weeks,” Frost told BBC Future.

In dugout canoes they ply the ocean between Malaysia, the Philippines and Indonesia, fishing with nets and lines. As sea nomads, they do not consider themselves tied to any country.

Freedivers : The sea gypsies of Malaysia and Indonesia, are renowned natural freedivers. Traditionally, they are born, live and die at sea, and fish by diving 20m (more than 65ft) underwater for minutes at a time on one breath. At this depth, water pressure is almost three times what it is on the surface, squeezing lungs already deprived of oxygen. "Not enough research has been done to know if it wears off when you're not diving," says Farrell. "But I know people who do a lot of deep training - as Sulbin does - whose blood is like that of people living at high altitude."

Underwater eyesight : The Bajau, in common with other coastal dwelling people, have unusually strong underwater vision. Their eye muscles have adapted to constrict the pupils more, and to change the lens shape to increase light refraction. This makes their underwater eyesight twice as strong.

Amphibious Human : The Bajau fisherman Sulbin in the video shows us how biology and culture are inseparable because what he does ends up shaping his body, but only because he grew up around people who knew how to manage becoming human in this distinctive amphibious way and because his adaptations play upon how his nervous system works, including some intriguing quirks.

The infinite multiverse hypothesis : Three physicists recently came together to debate the pros and cons of the hypothesis.

Many worlds : Quantum objects can be described using what's called a wavefunction, which can predict where it's going to be and how it's moving. But those predictions take the form of probabilities.

The problem is that, as far as we know, there's no reason to have the wavefunction stop working. Yet measurements, in Levin's terminology, "break" the wavefunction. In the many-worlds interpretation, the wavefunction keeps working, but reality breaks, or at least fragments a bit. In this view, there are particles in every location the wavefunction predicts we'll find them. It's just that those locations end up in different universes once the measurement happens.Even Levin, the ostensibly agnostic moderator, finished her description by saying, "obviously, it's a bit nuts."

The other multiverse problem : Thanks to a different theory: cosmic inflation, the sudden and rapid expansion of the universe allows the Big Bang to produce a universe that looks like the one we inhabit. If inflation is right—and most physicists think it is—then the universe we see is only a small fraction of the whole. And, if you could somehow go past the observable universe, you'd come to a region where inflation is an ongoing process, rapidly expanding space and ultimately creating additional universes.

Philae prepares to land : After circling comet 67P/Churyumov-Gerasimenko for some time now, The Rosetta robotic spacecraft is getting ready to maneuver to a location where the lander Philae can be deployed.

If that spin holds steady at about 12.4 hours per rotation Philae should hit the right spot – but as the comet heats up and loses material the spin rate may shift by tiny amounts.

With some luck it should all work out fine, but it’s a bit like a fairground game where you try to hit a crazily tumbling target for the prize. If Philae lands successfully it’ll fire up a host of experiments and instruments – using up the energy of its primary battery over the course of about 64 hours. After that point Philae’s life-expectancy hinges on how well its solar panels can recharge those batteries – hopefully well enough to take it through 67P/C-P’s closest approach to the Sun in March 2015.

Science Fiction to Science : This is a fascinating story which I came upon. Knight-Ridder and a skunkworks team dreamed up an idea which was to come true in 15 years. Roger Fidler dreamt up a 'tablet' computer. One wonders how much of Apple's tech is not actually stolen from someone else?

Article Extract: The Knight-Ridder company was once the USA's second largest publisher of newspapers. The company had the foresight to establish a small team to explore how the digital revolution might change the way future consumers would access news and other information, and how newspapers could adapt in order to retain their audiences. The work of this team, led by Roger Fidler, proved impressively prescient. It conceived of and described an entirely new product, a tablet computer weighing about a kilogram with a colour touch screen and resolution as good as paper — and identifiedh... more »

Article Extract: The Knight-Ridder company was once the USA's second largest publisher of newspapers. The company had the foresight to establish a small team to explore how the digital revolution might change the way future consumers would access news and other information, and how newspapers could adapt in order to retain their audiences. The work of this team, led by Roger Fidler, proved impressively prescient. It conceived of and described an entirely new product, a tablet computer weighing about a kilogram with a colour touch screen and resolution as good as paper — and identified how consumers would use such a device not merely as a tool to access news and information, but also to communicate and wirelessly purchase goods and advertised products.

Shortly after this video was made, Knight-Ridder closed Roger Fidler's research project. A changed corporate leadership saw no urgency in pursuing the concept of the tablet. After all the newspaper business was still very profitable, and Roger's tablet was considered to be so far into the future as to be science fiction.

Jury decision sounds suspicious : Samsung lawyers presented the Knight-Ridder research as "prior art", arguing that many of Apple's patents were not of its own original invention. The jury did not agree.

Insects benefit from following the leader : While we often talk about leadership in the human context, scientists have discovered that in the case of the Sawfly larvae, they actually benefit from following a leader. Not only do the followers benefit, but the leader does as well - and they do this all democratically! Swarm behavior has always fascinated me, and some of the things we learn about insects is quite interesting...

Social behavior : Scientists have shown for the first time that when insect larvae follow a leader to forage for food, both leaders and followers benefit, growing much faster than if they are in a group of only leaders or only followers. The work gives new insight into why such social relationships evolve in insects, and why they are maintained.

Social behavior : Scientists have shown for the first time that when insect larvae follow a leader to forage for food, both leaders and followers benefit, growing much faster than if they are in a group of only leaders or only followers. The work gives new insight into why such social relationships evolve in insects, and why they are maintained. The study looked at larvae of the iconic Australian steel-blue sawfly Perga affinis often known as 'spitfires'. Sawfly larvae can grow to 7cm long and forage nocturnally in Australian Eucalyptus trees, forming large groups that can strip all of the leaves from a tree in a few days.

Leadership and followership works : "We see that leaders only benefit from being leaders if they have followers, and that followers only benefit if they have leaders. There is no use being a shepherd without sheep or sheep without a shepherd." Study co-author Professor Mark Elgar said that while leaders do not differ in growth rates or weight, they may acquire other benefits such as lower predation or enhanced immune function. "The next stage of our research is to find out how certain larvae become the leaders in a group and how they are communicating directions and encouragement to their followers," added Prof Elgar.

Democratic leadership : Sawfly societies operate democratically, with leaders and followers co-operating to decide on group movements. This contrasts with other animal societies, such as baboons and wolves, where leaders are despotic, dominating their followers. Ms Hodgkin, a PhD candidate at the University of Melbourne said the team was keen to understand why the larvae followers allow others to determine the group's movements.

Speed boost : Destin, of the YouTube video series Smarter Every Day, and Phil Torres, who’s a conservation biologist and intrepid rainforest explorer, come across this large, writhing ball of caterpillars in the Amazon rainforest. And seemingly immediately, Destin has an idea – what if the reason that the caterpillars are crawling over each other is to get a speed boost? So he goes home, and designs a wonderfully elegant experiment, using Lego, to prove his point. I just love how this simple Lego powered explanation gets right to the heart of this strange phenomenon.
