Joaquin Ferguson0This is a curated circle. It's a circle of people I started following in January, and who have consistently posted something at least once a week during all of February, March, and so far in April, about three months.

Graeme McRae23,459Graeme's January Circle . . . This is a curated circle. It's a circle of people I started following in January, and who have consistently posted something at least once a week during all of February, March, and so far in April, about three months. If you want an interesting stream, you should add this circle. If you're interested in how I curated this circle, and why I think it makes for a really great stream, read on. . .How did these people get in the circle?. . . They must have posted something interesting, at least once, because I don't follow people unless they post something interesting. By now, you're probably not surprised by the number of people on G+ whose pages are full of repeated posts, videos without comments, "what's up" and other uninteresting things. I don't follow those people.How did they stay in the circle since January?. . . After I add someone, I keep them in the circle of people I added around the same time. Then, several times a week, I go through all my circles and delete people who haven't posted (something visible to me) in the last 7 days. So the people who are left in the circle are consistent posters. That says something important about them, because consistency is a proxy for quality.Consistency is a proxy for quality. Why is that?. . . I'll admit it: I don't have the science to back up that wild statement, but I'll tell you why I believe it to be true. People who post crap don't get a lot of followers, and the few followers they have don't bother to engage. After a while, the crappy-posting people start to think G+ is a ghost town, and they lose interest. On the other hand, the people who share (or re-share) interesting things get followers and engagement, slowly at first, but ever increasing, and this outpouring of love is what keeps them going. That's what I think anyway, and I'm sticking to it.People who share interesting things get lots of followers. . . This is another half-baked theory of mine, but hear me out. You might think this makes sense: Google+ offers suggestions of people to follow, especially to new users. Google+'s only source of names to suggest are other G+ers like yourself. The G+ers who have the most engagement are the ones Google+ knows will be good to follow, so these people get put out as suggestions more often, and some percentage of those suggestions are taken up. So the more engagement you have, the more Google+ will sugggest you as a person to follow, and so the more followers you'll get. Completing the theory: the more interesting the stuff you share (or reshare), the more engagement you'll get, and hence the more followers you'll get.How can I get in your circle?. . . Don't bother trying to "get into" this circle. This circle isn't for you to get into. Think of it the other way around. This circle is for you to add, so you can follow a bunch of interesting and consistent people. The stream from this one circle will be chock-full of fascinating content for you to reshare. People will start to notice your reshares, and they will engage with you, and then Google+ will "notice" (it's a computer, but let's anthropomorphise, shall we?) you and suggest you to others, who will then follow you.No, really. How can I get in your circle?. . . First, unfollow me, then wait, oh, about a week. Spend that week posting a shitload of interesting things. Then follow me. Since you're so interesting, Google+ will notify me that you followed me (G+ doesn't notify me about every follower). I'll look at your posts, find one interesting, and follow you. Then, remember to post something every few days. Finally, after two or three months, I might post the circle for the mo2014-04-11 23:47:335009716

Earth May Be in Early Days of 6th Mass Extinction

Earth may be in the early stages of a sixth mass extinction, an international team of scientists says.

Animals and plants are threatened. More than 320 land vertebrates have gone extinct since 1500, the researchers said. The world’s remaining animals with backbones are 25 percent less abundant than in 1500 - a trend also seen in invertebrate animals, such as crustaceans, worms and butterflies, the scientists reported.

The previous mass extinction, which wiped out the dinosaurs, happened about 65 million years ago, likely from a catastrophic asteroid that collided with Earth. In contrast, the looming sixth mass extinction is linked to human activity, Rodolfo Dirzo, a professor of biology at Stanford University in California, said in a statement. Dirzo is the lead author of the new review of past research on thet... more »

Spinosaurus aegyptiacus: Semiaquatic adaptations in a giant predatory dinosaur

An unusual fossil whose parts were flung across two continents appears to be the first known semi-aquatic dinosaur, according to a report published Thursday by the journal Science. The differences between this Spinosaurus and other theropods are apparent from head to toe. Most theropods, like T. rex, ran on two powerful legs and had small, spindly arms. By contrast, the 50-foot-long Spinosaurus had muscular arms with blade-like claws that could have nabbed slippery prey, and shorter legs that were ill-equipped to walk on land.

Lead author Nizar Ibrahim, a palaeontologist from the University of Chicago, said: "It is a really bizarre dinosaur - there's no real blueprint for it. It has a long neck, a long trunk, a long tail, a 7ft (2m) sail on its back and a snout like a crocodile.... more »



Spinosaurus aegyptiacus: Semiaquatic adaptations in a giant predatory dinosaur

An unusual fossil whose parts were flung across two continents appears to be the first known semi-aquatic dinosaur, according to a report published Thursday by the journal Science. The differences between this Spinosaurus and other theropods are apparent from head to toe. Most theropods, like T. rex, ran on two powerful legs and had small, spindly arms. By contrast, the 50-foot-long Spinosaurus had muscular arms with blade-like claws that could have nabbed slippery prey, and shorter legs that were ill-equipped to walk on land.

Lead author Nizar Ibrahim, a palaeontologist from the University of Chicago, said: "It is a really bizarre dinosaur - there's no real blueprint for it. It has a long neck, a long trunk, a long tail, a 7ft (2m) sail on its back and a snout like a crocodile. And when we look at the body proportions, the animal was clearly not as agile on land as other dinosaurs were, so I think it spent a substantial amount of time in the water."

The new paper: Described adaptations for a semiaquatic lifestyle in the dinosaur Spinosaurus aegyptiacus. These adaptations include retraction of the fleshy nostrils to a position near the mid-region of the skull and an elongate neck and trunk that shift the center of body mass anterior to the knee joint. Unlike terrestrial theropods, the pelvic girdle is downsized, the hind limbs are short, and all of the limb bones are solid without an open medullary cavity, for buoyancy control in water. The short, robust femur with hypertrophied flexor attachment and the low, flat-bottomed pedal claws are consistent with aquatic foot-propelled locomotion. Surface striations and bone microstructure suggest that the dorsal “sail” may have been enveloped in skin that functioned primarily for display on land and in water.

Dreadnoughtus Today is so exciting for a ton of palaeontologists, students, researchers, and dinosaur fans. The video gives a bit of history to where this titanosaur was discovered back in 2005. Almost ten years later and it’s finally gone public.

These fossils spent a lot of time being excavated out of the matrix they were found in; around 4 years with multiple labs working tirelessly to clean and repair them. With such a huge specimen, a lot of man power was required.

You can read the article about Dreadnoughtus here on Drexel University’s website: http://drexel.edu/now/archive/2014/September/Dreadnoughtus-Dinosaur/

Frisbees are a popular summertime toy, but they involve some amazing physics, too. Two key ingredients to their long flight times are their lift generation and spin. A frisbee in flight behaves very much like a wing, generating lift by flying at an angle of attack. This angle of attack and the curvature of the disk rim cause air to accelerate over the top of the leading edge. Airflow over the top of the disk is faster than that across the bottom;  thus, pressure is lower over the top of the frisbee and lift is generated.

Aerodynamic lift and drag aren’t enough to keep the frisbee aloft long, though. Spin matters, too. If the frisbee is launched without spin, gravity acts on it through its center of mass, but lift and drag act through a point off-center because lift tends to be higher on the front of the disk than the back. This offset between gravitational forces and aerodynamicfo... more »

Aerodynamic lift and drag aren’t enough to keep the frisbee aloft long, though. Spin matters, too. If the frisbee is launched without spin, gravity acts on it through its center of mass, but lift and drag act through a point off-center because lift tends to be higher on the front of the disk than the back. This offset between gravitational forces and aerodynamic forces creates a torque that tends to flip the frisbee.

By spinning the frisbee, the thrower gives it a high angular momentum acting about its spin axis. Now instead of flipping the disk, the torque caused by the offset forces just tips the angular momentum vector slightly. Physically, this is known as spin stabilization or gyroscopic stability. Tomorrow we’ll take a closer look at airflow over the frisbee.  ( Image credit: A. Leibel and C. Pugh, source video: Frisbee Toy Box Physics ; recommended papers by: V.

Supersonic submarine might travel Shanghai-San Francisco in 100 minutes

Chinese scientists are very close to creating a supersonic submarine capable of traveling from Shanghai to San Francisco in less than two hours. Researchers found a way to generate a huge air bubble around the submarine reducing drastically the water friction and therefore augmenting its speed.

This technique is called supercavitation and was developed originally by Soviet military during the Cold War. They built a supersonic torpedo called Shakval that was able to reach 230 mph (370 kmh)—In theory, a supercavitating vessel could reach the speed of sound underwater, or about 3603 mph (5,800km/h.) Chinese researchers solved some of the problems Russian faced with Shakval but not all of them.

Chinese researchers solved some of the problems Russian faced with Shakval but not all of them. South China Morning Post writes: Professor Wang Guoyu, head of the Fluid Mechanics Laboratory at Beijing Institute of Technology who is leading another state-funded research project on supercavitation, said the global research community had been troubled for decades by the lack of innovative ideas to address the huge scientific and engineering challenges. "The size of the bubble is difficult to control, and the vessel is almost impossible to steer," he said. While cruising at high speed during supercavitation, a fin could be snapped off if it touched the water because of the liquid's far greater density.

Antony Gormley -  Inner space everted and spaced out

Sir Antony Mark David Gormley, born in 1950, is a world-renowned British sculptor. Almost all his work takes the human body as its subject, with his own body, "the only part of the material world that he inhabits", used in many of them as the basis for the metal casts. His work attempts to treat the body not as an object but a place. 

"The body is a language before language. When made still in sculpture it can be a witness to life and and it can talk about this time now."

"The body is a spaceship and an instrument of extreme subtlety, that communicates whether we recognize its communications consciously or not."

Antony Gormley -  Inner space everted and spaced out

His work attempts to treat the body not as an object but a place. 

"The body is a language before language. When made still in sculpture it can be a witness to life and and it can talk about this time now."

"The body is a spaceship and an instrument of extreme subtlety, that communicates whether we recognize its communications consciously or not."

Gormley won the Turner Prize in 1994 with Field for the British Isles but is perhaps best known for his public sculpture Angel of the North and his spectacular transformation of Crosby Beach near Liverpool into "Another Place". 

"The place made the piece." -Gormley

Personally I think his works are at their best when they are exhibited together in groups. You know that point where a word, if you endlessly keep repeating it, starts to lose its familiarity and meaning? His sculptures generate that same alienating feeling but for your concept of the human body. What makes it even better is that, while you are repeating your word, Gormley switches out a few letters but so slowly that you don't pick up on it... Ultimately you end up wondering why a block of concrete with holes in it looks so sad. Aftereffects of his show include a free rendition of "They Live" upon exit. ;)

"There's that idea of who we are and what we look like. Your physiognomy belongs to me more than you because I'm looking." -Gormley

It's perhaps not surprising that work exploring the limits at which forms can retain human qualities should bring to mind transhumanism but much of his work purposefully edges toward the futuristic. With names like Natural Selection, Hive, Critical Mass and Quantum Cloud, one could imagine all these shapes being expressions of a singular constantly changing entity.

"Well, bio-cybernetics: we can now be creative interventionists in the construction of transgenic life forms. Morphological transmission is part of my work." - Gormley

Fluorescent oil lets NASA engineers see flow patterns over an experimental aircraft

Researchers at NASA's Langley Research Center in Hampton, Va., use all sorts of tools and techniques to learn more during the development of aircraft and spacecraft designs.

In this photo, engineers led by researcher Greg Gatlin have sprayed fluorescent oil on a 5.8 percent scale model of a futuristic hybrid wing body during tests in the14 by-22-Foot Subsonic Wind Tunnel.

The oil helps researchers "see" the flow patterns when air passes over and around the model. Those patterns are important in determining crucial aircraft characteristics such as lift and drag.

Algal Blooms and Microcystins: The Fouling of Lake Erie

A Colorful History : Often called blue-green algae, cyanobacteria are neither restricted to blue and green hues nor are they true algae. They bring a carmine tinge to the Red Sea and make the Spirulina-eating African flamingos blush pink. When these simple bacteria appeared 3.5 million years ago, they produced oxygen by photosynthesis, changing the fate of the earth forever. Then in the Precambrian era, according to the theory of endosymbiosis, they were co-opted as chloroplasts into the cells of green plants. They also form nitrogen-fixing nodules in the roots of plants and partner with fungi to colonize barren new lands as lichen. Little wonder that scientists consider them the most successful group of microbes ever. But as Shakespeare mused: Why then, can one desire too much of a good thing?

Algal Blooms and Microcystins: The Fouling of Lake Erie

A Colorful History : Often called blue-green algae, cyanobacteria are neither restricted to blue and green hues nor are they true algae. They bring a carmine tinge to the Red Sea and make the Spirulina-eating African flamingos blush pink. When these simple bacteria appeared 3.5 million years ago, they produced oxygen by photosynthesis, changing the fate of the earth forever. Then in the Precambrian era, according to the theory of endosymbiosis, they were co-opted as chloroplasts into the cells of green plants. They also form nitrogen-fixing nodules in the roots of plants and partner with fungi to colonize barren new lands as lichen. Little wonder that scientists consider them the most successful group of microbes ever. But as Shakespeare mused: Why then, can one desire too much of a good thing?

Toxic Blooms: Ever opportunistic, cyanobacteria can rapidly increase in biomass to form thick green scum euphemistically known as blooms on the surface of shallow lakes. Over-fed with nutrient run-off from fertilized farmlands, sewage disposal or industrial waste, the blooms in turn feed bacteria, which then consume dissolved oxygen, killing off fish and creating dead zones. That’s not all: the blooms produce potent toxins that target the liver, brain and skin. The worst offenders are microcystins: cyclic compounds that fit snugly into the pocket of a class of enzymes known as protein phosphatases (image) and block their tumor-suppressing activity. In 1996, 76 dialysis patients at a clinic in Caruaru, Brazil, died from acute liver failure after water contaminated with microcystins was used in renal dialysis treatment. Their cyclic structure makes microcystins resistant to most water treatment processes, and boiling only concentrates the toxin. The building blocks that make up the toxin are unusual (non-protein amino acids) , and cannot be broken down by enzymes found in our cells. Recently, algal blooms in Lake Erie forced the shut-down of the entire water system in the city of Toledo, leaving half a million residents with no water. Given that this is becoming "the new normal" (http://goo.gl/dPyrtG) in many freshwater supplies around the world, what is the solution?

Bioremediation: There are no short term solutions to the blooming problem! We can cut back on fertilizer use, although faster acting, more efficiently utilized phosphate formulations actually encourage algal growth. Fortunately, we can exploit the chemical warfare in the battleground of the blooms themselves. It's thought that cyanoblooms produce these toxins to protect themselves from heat and oxidation stress. But competing bacteria like Sphingomonas secrete enzymes that can degrade microcystins. Research on natural bioremediation by culturing beneficial bacteria and studying their genetic and biochemical pathways could help nip future blooms in the bud.

It can either be converted to biogas, or used in secondary pharmaceutical and food products. Residents have no heating bills and the building currently reduces overall energy needs by 50%.

A snake’s flicking for taste - no, it’s for 3D smell-o-vision & much more

Most animals with tongues use them for tasting, to clean themselves or others, or to capture or manipulate their prey. A few, including humans, also use them to make sounds. Snakes do not use their tongues for any of these things.

Oscillating tongue-flicks are unique to snakes. They allow snakes to sample 100 times as much air as the simple downward extension of the tongue. The tongue then transfers these molecules to the Jacobson’s Organ via the mouth floor. Evidence suggests that male Copperheads can also find and follow females using oscillating tongue-flicks to detect airborne pheromones, although the details of how they determine direction using such dispersed and transient odors are still poorly understood.

Dale, who was a member of an international task force – dubbed SolarMAX – set up to identify the risks of a solar storm and how its impact could be minimized, explains how it is only a matter of time before an exceptionally violent solar storm is propelled towards Earth. Such a storm would wreak havoc with our communication systems and power supplies, crippling vital services such as transport, sanitation and medicine.

"Without power, people would struggle to fuel their cars at petrol stations, get money from cash dispensers or pay online. Water and sewage systems would be affected too, meaning that health epidemics in urbanized areas would quickly take a grip, with diseases we thought we had left behind centuries ago soon returning," Dale writes.

Earth May Be in Early Days of 6th Mass Extinction

Earth may be in the early stages of a sixth mass extinction, an international team of scientists says.

Animals and plants are threatened. More than 320 land vertebrates have gone extinct since 1500, the researchers said. The world’s remaining animals with backbones are 25 percent less abundant than in 1500 - a trend also seen in invertebrate animals, such as crustaceans, worms and butterflies, the scientists reported.

The previous mass extinction, which wiped out the dinosaurs, happened about 65 million years ago, likely from a catastrophic asteroid that collided with Earth.

Earth May Be in Early Days of 6th Mass Extinction

Earth may be in the early stages of a sixth mass extinction, an international team of scientists says.

The world’s remaining animals with backbones are 25 percent less abundant than in 1500 - a trend also seen in invertebrate animals, such as crustaceans, worms and butterflies, the scientists reported.

The previous mass extinction, which wiped out the dinosaurs, happened about 65 million years ago, likely from a catastrophic asteroid that collided with Earth. In contrast, the looming sixth mass extinction is linked to human activity, Rodolfo Dirzo, a professor of biology at Stanford University in California, said in a statement. Dirzo is the lead author of the new review of past research on the topic, which suggests Earth is in the early days of this sixth mass extinction.

A past study, which involved data from the fossil record and modern-day conservation biology, suggested Earth could enter such a mass extinction within the next 300 to 2,000 years. That study was detailed in the March 2, 2011, issue of the journal Nature.

Up to one-third of all vertebrates are threatened or endangered, the researchers said. Large animals - such as elephants, rhinoceroses and polar bears - have the highest rates of decline, which is a trend shared by other mass extinctions. These large animals are at particular risk because they tend to have few offspring and low population growth rates. Hunters and poachers, however, find their fur, meat, tusks or horns attractive targets.

Losing a species of large animal can have unexpected effects on the ecosystem and nearby human developments, a process known as defaunation. In one study, researchers isolated patches of land from animals, including zebra, giraffes and elephants. Without the animals, the grass and shrubs grew tall, and the soil became looser. Rodents quickly took over and doubled in numbers, eating the seeds from the plants and living in the patchy soil that was relatively predator-free.

Rodents can carry diseases and parasites that infect people, the researchers said.

"Where human density is high, you get high rates of defaunation, high incidence of rodents and thus high levels of pathogens, which increases the risks of disease transmission," Dirzo said. "Who would have thought that just defaunation would have all these dramatic consequences? But it can be a vicious circle."

The decline of big animals affects not only vegetation, but also invertebrates. In the past 50 years, the human population has doubled, and the number of invertebrate animals has dropped by 45 percent, the researchers said. Much of the loss is a result of habitat destruction and global climate disruption, the researchers said.

SciTech #ScienceSunday Digest, 30/14.
Affecting cognitive decline, negative mass, printing complete boards, atmospheric waveguides, spinning nanorods, restoring insulin sensitivity, wave tractor beams, biomimicry for audio chips, solar passive cooling.

1. A (Reversible?) Mechanism for Age-Related Cognitive Decline.
Recent studies show that extracellular matrix proteins in the hippocampus of animals undergo robust and progressive upregulation over time, increasing with age and believed to directly contribute to cognitive decline by inhibiting synaptic plasticity and cell mobility https://www.fightaging.org/archives/2014/07/involvement-of-the-extracellular-matrix-in-age-related-memory-loss-in-mice.php. The studies were conducted in mice and so confirming the effect in human brains will be important. Given that only one group of four proteins of the extracellular matrix increased strongly, this may present a convenient target to down-regulate protein expression and restore cognitive function. Speaking of cognitive decline a non-invasive retinal imaging technique claims to detect changes indicating Alzheimer’s 15 to 20 years before clinical diagnosis http://www.cedars-sinai.edu/About-Us/News/News-Releases-2014/Study-of-Noninvasive-Retinal-Imaging-Device-Presented-at-Alzheimers-Conference.aspx. 

2. Proving Negative Mass can Exist in the Universe.
The consensus in cosmology has been that negative mass cannot exist in the Universe due to theoretical conflict with things like General Relativity. However, recent analysis and new solutions to General Relativity imply that negative mass could indeed exist in our Universe without conflicting existing theories https://medium.com/the-physics-arxiv-blog/cosmologists-prove-negative-mass-can-exist-in-our-universe-250a980320a7. Turns out that if negative mass exists it would create a plasma in space that would absorb gravity waves, and so providing a plausible answer for why gravity waves have never been detected despite increasingly sensitive instruments. Whether there is a threshold frequency above which gravity waves might propagate through such a plasma is an interesting avenue of inquiry that might provide an interesting means to test the theory. A minority of cosmologists postulate that antimatter has negative mass but there has not yet been an empirical test one way or the other http://en.wikipedia.org/wiki/Gravitational_interaction_of_antimatter. 

3. All-In-One Printer for Functional Circuit Boards.
Representing another little evolution in the technology for printable electronics, the Squink printer takes your designs for a circuit board, prints traces with conductive ink, prints conductive glue where the components will attach, and then finally engages a pick-n-place robotic tool to place the components - such as resistors, diodes, ICs, etc - where they are supposed to go http://gizmodo.com/this-all-in-one-printer-churns-out-completely-functiona-1608373786. Once the wet-phase material has cured and dried the printed board can be fired up and used; great little advance for hobby and prototyping applications with commensurate cost and time savings. Should get more sophisticated over time too.

4. Punching Laser Waveguides in Air.
Short, powerful laser pulses can now be used to create the equivalent of optical waveguides in air, the core of which has a higher refractive index than the outside, and so allowing concentrated focusing of subsequent laser light - avoiding the typical spreading and loss of intensity with distance that light in air experiences http://cmns.umd.edu/news-events/features/2356. The laser pulses last only a trillionth of a second, but the “fibers” or waveguides formed last for milliseconds; a very long time in comparison and longer than needed to take advantage of by firing more powerful beams down the guide with little or minimal loss of energy. While longer distances still need to be tested but there are very promising applications in high-bandwidth air-based communications, long-range chemical analysis, over-air power transmission, and laser weapons to name a few. 

5. Rapidly Spinning Nanorods for Chemistry and Medicine.
Nanorods injected into the bloodstream of mice and rapidly spun up by magnets have been shown to double the effectiveness of blood-clot busting drugs that help with stroke; the rods act like a mixing tool, shaking the clots and helping the drug be more effective and ideally allowing a much lower dose (and lower side effects) to achieve the same therapeutic result http://spectrum.ieee.org/nanoclast/biomedical/devices/nanoparticles-improve-stroke-treatment/. Further, nanorods measuring 300nm by 2000nm, placed in solution will rotate at 150,000 rpm when stimulated by 3MHz ultrasound, and act as a very effective and dispersed mixing mechanism with possible applications in speeding up chemical reactions http://phys.org/news/2014-07-ultrasonically-propelled-nanorods-dizzyingly-fast.html. 

6. Injecting a Single Protein Restores Insulin Sensitivity and Normal Glucose Metabolism.
Injecting the protein FGF1 (fibroblast growth factor) into mice with type 2 diabetes results in the restoration of normal insulin sensitivity and glucose metabolism for up to two days; sustained treatment could possibly cure type 2 diabetes in humans http://www.salk.edu/news/pressrelease_details.php?press_id=2037. The molecule does all of this without causing the normal side effects and other risks associated with most other diabetes drugs. While promising this is still early stage; to progress to humans the group wants to discover the biochemical pathway that causes the effect, and will also need to create modified proteins that stimulate insulin sensitivity without stimulating cell growth (which this one does).

7. Creating Tractor Beams with Waves.
It has previously been demonstrated that laser light can exert both a pushing and a pulling force on objects. Interestingly, these concepts have now been scaled up and applied to conventional water waves, in which the propagation and timing of water waves can either push or pull floating objects https://medium.com/the-physics-arxiv-blog/tractor-beam-created-using-water-waves-8d9271134c50. That’s a backward pulling force from forward propagating waves, and a pretty interesting fluid dynamics result. Applications could include feeding the knowledge back into the laser work for better optical tractors, better tracking of ocean-borne ships, rubbish, and debris, more efficient cleanup of oil spills, and fun applications with wave pools. 

8. Biomimicry Inspires Super Acoustic Chips.
Drawing on inspiration of a certain fly’s auditory apparatus - which it uses to precisely target crickets on which to birth its larvae - a chip-based replica has been engineered that uses a similarly-structured 3mm square mechanical beam on silicon with a piezoelectric coating that is able to very accurately sense displacement modes corresponding to sound direction and distance http://spectrum.ieee.org/tech-talk/at-work/test-and-measurement/mimicking-the-super-hearing-of-a-crickethunting-fly. Such a miniaturised chip-based acoustic sensor has military applications in sensing the direction and distance of sound sources, but it might also help improve this indoor positioning system based on echolocation http://www.technologyreview.com/view/529176/an-indoor-positioning-system-based-on-echolocation/, or even allow simple devices such as mesh networked sensors to cheaply and easily determine the direction and distance to other devices. 

9. Engineering Passive Cooling into Solar Cells.
As good as current solar panels have become they suffer significant losses in energy conversion efficiency when they become too hot and proposals to install active cooling systems almost defeat the point due to the energy required by the pumps. A new passive cooling system involves applying a thin layer with a pattern of micropyramids onto the panels that are optimised to draw away heat and shed it into the atmosphere as infrared radiation http://www.gizmag.com/self-cooling-solar-cells/33061/. The coating lets visible light in and and infrared light out, and should lower operational temperatures, increase efficiency, and lengthen operational lifetimes. 

10. Project Loon Matures After One Year.
Twelve months after first being announced Google’s Project Loon has started to mature, achieving new and significant milestones with its high-altitude balloons designed to provide wireless, ground-level Internet access http://www.wired.co.uk/news/archive/2014-06/17/google-loon-one-year-on. Now considered to be more likely than not to be a viable commercial operation in future, the balloons are providing up to ten times the bandwidth, navigational abilities, and flight times compared to one year ago. A year ago the balloons remained aloft for a few days; now an average of 75 days is common and many pass 100 days with some circling the globe three times. LTE communications have been added and download speeds reach up to 22 MB/s compared to 2 MB/s. One step closer to seamless global wireless Internet access.

Ward's "traffic light" reaction

A solution of glucose, sodium hydroxide, and indigo carmine, when shaken, will change from yellow to red to green. Left to sit, it will revert to red again, then yellow, and the process can be repeated. The indigo carmine is green when oxidized, yellow when reduced, and red in the intermediate semiquinone state.
