Pat Kight14,338@113977984500465768287  said she wants the Scavengers under her tree for Christmas. Let's do it! Drop by, say hi to the friends you've made during the Autumn Scavenger Hunt, share a few photos of your own festivities. (Invite going out to the Autumn Scavengers circle, but I've enabled the "on air" feature so folks from past Scavenger events can see it, and you can invite other Scavengers).Scavengers Holiday Party2013-12-24 21:00:00151 
Science on Google+502,427Posterside Hangouts is a new Hangouts On Air, which is hosted by the Science on Google+ Community (http://goo.gl/uhJCN). The main goal of this HOA series is to recreate a poster session-like atmosphere here on G+, so researchers can present their recent findings. Presentations will be grouped by discipline and individual presentations will last approximately 10 – 15 minutes.Do you have a recent conference presentation, manuscript, or book that you would like to share with the Google+ community? Do you want to give your undergraduate or graduate students practice presenting their research? If yes, then let us know by filling out this short form: http://goo.gl/e0KPhE.================================Psychology Talks for Posterside Hangouts #1, Authors (Affiliations)When audition dominates vision: Evidence from cross-modal statistical learning+Chris Robinson (The Ohio State University at Newark)Automatic selection of eye tracking variables in visual categorization for adults and infants+Samuel Rivera (The Ohio State University at Columbus)Foreign accent does not influence cognitive judgments+Andre L.

Research examining interference effects shows that auditory input often interferes with processing of visual input in young children (i.e., auditory dominance effect), whereas visual input often interferes with auditory processing in adults (i.e., visual dominance effect). The current study used a cross-modal statistical learning task to examine modality dominance in adults. Participants ably learned auditory and visual statistics when auditory and visual sequences were presented unimodally and when auditory and visual sequences were correlated during training. However, increasing task demands resulted in an important asymmetry: Increased task demands attenuated visual statistical learning, while having no effect on auditory statistical learning. These findings are consistent with auditory dominance effects reported in young children and have important implications for our understanding of how sensory modalities interact while learning the structure of cross-modal informationScience on Google+ Posterside Hangouts #12013-08-13 02:30:0099

It is also a way to thank you and to inform you of my consideration.You will find in these two circles all the people I follow regularly since my first steps on Google+ and which accompany me for soon two years in this beautiful adventure, bringing every day, by their sympathy, their humor, their knowledge, their generosity and their open-mindedness, a bit extra to my everyday life.I do not know everybody, I have crossed the path with some, I communicate more with some and many people became friends, thing which I did not expect by landing here.When I began, I was lucky enough to discover new interesting people, thanks to the system of circles sharing, and I hope that these both will be for you of the same utility.If you add a “plus”, maybe it will have an impact on climate change,if you share this circle, maybe Putin is going to get married with an ukrainian women in 2014,if you include me in your circles, maybe it will solve the problem of hunger in the world,Maybe ... but in fact, nothing is sure ;)A good day to all :)With a special thought for #dirktalamasca   #sharedcircles   #circles   #circlesharing  2014-03-31 15:25:36432622658

Jack-o-Lantern Sun

Even the sun is getting into the Halloween spirit, as seen from this +NASA image from earlier this month.

from NASA's site:
Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 Ångströms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.

Data is Plural

In heavy editing mode right now, and I am amazed at how many folks who do science for a living don't know that the word "data" is plural. 

Or perhaps they're all just making a sick joke at my expense based on this wonderful xkcd comic. Unfortunately, our papers don't include any Star Trek references, so I'll never know....

#augh!

h/t to my 12 year-old son, who not only knows that "data" is plural, but also has memorized every possible xkcd comic, and can find one fitting any circumstance....

Christmas Math
Putting the STEM into trees

As #ScienceSunday winds to a close in my part of the world, and Christmas approaches, it seems fitting to share this Christmas Tree a la Math from last year for folks who hadn't seen it yet.

Even if you don't celebrate the holiday, you can celebrate the STEM!

Christmas Tree a la Math

The delightful tree below is brought to you by math (aka +Kenneth Kornacki of Aurum design: http://goo.gl/y4vPtM)

And tis the season to celebrate math in other trees as well.

In phys.org, Michael Rose turns Pascal's triangle into the 12 days of Christmas, with each day describing a different hidden secret in Pascal's triangle. I've taken his topics and put them together to form the full lyrics, so you can sing along! From his post:

Blaise Pascal was a 17th century French mathematician. He was primarily interested in using the triangle to advance his studies in probability theory – a field which he more or less invented in correspondence with Pierre de Fermat, after a gambling friend asked Pascal for advice on how two dice players should divide up the pot if their game was interrupted early.

Although simple to make, the triangle hides many, many surprising patterns. So, with apologies to folk carols in general and Frederic Austin in particular…

On the first day of Christmas, the triangle gave to me…
Counting numbers (with symmetry).

On the second day of Christmas, the triangle gave to me…
Powers of two
and Counting numbers (with symmetry).

On the third day of Christmas, the triangle gave to me…
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the fourth day of Christmas, the triangle gave to me…
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the fifth day of Christmas, the triangle gave to me…
Prime ... num-ber things!
Fibonacci

and Counting numbers (with symmetry).

On the sixth day of Christmas, the triangle gave to me…
Intertwining petals
Prime ... num-ber things!
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the seventh day of Christmas, the triangle gave to me…
Hockey-stick addition
Intertwining petals
Prime ... num-ber things!
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the eigth day of Christmas, the triangle gave to me…
Squaring through addition

Intertwining petals
Prime ... num-ber things!
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the ninth day of Christmas, the triangle gave to me…
Binomial coefficients
Squaring through addition
Hockey-stick addition
Intertwining petals
Prime ... num-ber things!
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the tenth day of Christmas, the triangle gave to me…
All the combinations
Binomial coefficients
Squaring through addition
Hockey-stick addition
Intertwining petals
Prime ... num-ber things!
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the eleventh day of Christmas, the triangle gave to me…
Powers of eleven
All the combinations
Binomial coefficients
Squaring through addition
Hockey-stick addition
Intertwining petals
Prime ... num-ber things!
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

On the twelfth day of Christmas, the triangle gave to me…
Sierpinski's fractal!!
Powers of eleven
All the combinations
Binomial coefficients
Squaring through addition
Hockey-stick addition
Intertwining petals
Prime ... num-ber things!
Fibonacci
Triangular numbers
Powers of two
and Counting numbers (with symmetry).

More details about each of these mathematical treats and their link to Pascal's triangle in the OP here: http://goo.gl/X19oPm

And if you want to tinker around with your own triangles, there's a good description of the math here:
http://mathworld.wolfram.com/PascalsTriangle.html

...and, as an added bonus, the image below is reversable, so if you try hard enough, you can see it rotating to the left or rotating to the right. More on that phenomenon here: http://goo.gl/cj94pt and a kitteh version here, since it's almost #caturday : http://goo.gl/NfVfvm

Greased Lighting

Although I don't like the way the musical ends (why should Sandy change for Danny, and not vice versa?...), the production at my son's senior school was spectacular, and I did like the way the lighting in this shot from the end of the Greased Lightning number worked out.

Smoking Hot Science

One of my favourite #ScienceSunday posts this week, via +Lacerant Plainer - the combination of such a striking image (tiny pun intended) and a wealth of information made it a great share.

Check out our +ScienceSunday page for more great science shares, and even an occasional #SciencePunday groaner - yes, there is one today, but I'll let you discover it on your own ;)

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) 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.

Potted Potter and the Etsy Experience

In preparation for seeing Potted Potter next month (an unauthorized version of every Harry Potter book in just 70 hilarious minutes: http://www.pottedpotter.com/), my younger son is finally reading the series, and he now is totally hooked.

So he was super excited to find this present for a girl in his class on Etsy: a Bertie Bott's Every Flavour Bean bracelet! The beans here aren't edible, so he'll give her some of the candy version as well. 

In case other folks are looking for similarly Potter-inspired gifts for the holidays, Sammy's Beadworks has a huge collection, including a golden snitch necklace, a Dobby keychain, and a Mad Eye Moody ring (my favourite, since I collect eyes and brains :)) www.etsy.com/ca/shop/SammysBeadworks

And for folks who haven't used used Etsy yet, when you buy something, you get to give new Etsy users $5 off.  Just follow the link here, and hopefully that will work! http://etsy.me/1zvRbhf

Can be used now or saved for later. Sorry, won't work for previous Etsy-ers. 

If you visit Etsy, also be sure also to check out +Michele Banks 's shop, Artologica: http://goo.gl/nxMnC  

She's got amazing biology-inspired art, including original watercolour, scarves, ties, and even some petri-dish ornaments, based on neurons, blood cells, viruses, and more. ___

Vanishing Spirits
The art and science of single malt whiskey residue

Although they look like other-worldly landscapes of mysterious planets, the images here actually are leftover droplets of whiskey dried into the bottom of a glass, photographed through coloured lights.

It's one of the best art+science stories in a while: Photographer Ernie Button discovered the beauty of whiskey residue dried on the bottom of glasses, and physicist Howard Stone and his research group discovered the science behind the art.

According to a paper presented at a recent American Physics Society meeting (http://goo.gl/JCM6mj), the images result from the differential evaporation times of whiskey's two liquids: water and ethyl alcohol.

According to a paper presented at a recent American Physics Society meeting (http://goo.gl/JCM6mj), the images result from the differential evaporation times of whiskey's two liquids: water and ethyl alcohol.

The alcohol evaporates first, and as the ratio of the two liquids changes, so does the surface tension of the remaining droplet. A surfactant that occurs naturally in whiskey, reduces surface tension in the droplet, causing it to spread out, and polymers help bind it to the glass, creating intricate patterns as it spreads.

The result is nothing short of spectacular. And now, even non-whiskey drinkers can appreciate the beauty of this spirit.

So proud of my niece, Sophia, who is on the Rose City Crystals Novice Synchronized Skating team, which took first place at yesterday's competition in Anaheim. 

The timing on some of their moves is incredible, as they effortlessly weave in and out of chains of other skaters.

All the more impressive to me since the last time I skated, I nearly crashed into people every few minutes. :)

Micro-Scallop Robot Can Swim in Your Body
Researchers have created an artificial micro-swimmer which could swim through viscous fluids such as saliva and blood by opening and closing its shells at different rates.

The robot consists of two silicone polymer shells, each only 300 micrometres in size, connected by a single hinge. An external magnetic field is used to drive the movement of each shell by interacting with rare earth micro-magnets attached to each.

No Sitting Duck(bill) – How Hadrosaurs Won the Dino Derby
A new paper indicates that hadrosaurs – also known as duck-billed dinosaurs – were built for endurance rather than speed, and that this helped them avoid predators despite their lack of horns or armour.

Computer analysis of leg bones showed that a critical muscle known as the caudofemoralis attached lower on the thigh in hadrosaurs than in T-rexes. The extra leverage provided by this arrangement suggests that while T-rexes were capable of great bursts of speed, hadrosaurs could outrun them over long distances, especially if their herd members kept an eye out for predators.

The situation is analogous to the way modern zebras use herd mentality and endurance to outrun lions, even though the latter can run faster over short distances.

Thin Coating Could Boost Solar Efficiency
A thin layer of metal oxides could significantly boost the efficiency of solar cells, according to a new study.

Researchers have been working on a material made of the elements bismuth, iron, chromium and oxygen, which absorbs solar radiation. They discovered that by changing the temperature and pressure at which they deposit thin films of this material, they can control the wavelengths of light that the material can absorb.

The team created a stack of three layers of the material, each absorbing light at different layers, yet which is still only 200 nanometres thick. The stack converted significantly more light to energy than previous attempts with the same material.

The team has patented the discovery, and is planning to add the coating to traditional silicon solar cells, where they estimate it could boost maximum solar efficiency from 18 per cent to 24 per cent.

The new material also has unique electrical and magnetic properties that could be useful in devices such as electronic sensors or flash memory drives.

How Squirrels Avoid ‘Roid Rage
A new study shows that Arctic ground squirrels use anabolic steroids to beef up for winter hibernation, but that they have evolved systems to avoid the negative side effects.

Most hibernating animals burn fat during the winter, Arctic ground squirrels hibernate at such low temperatures that they need to burn muscle as well. A previous study showed that their levels of testosterone and other anabolic steroids spike in late summer to help them bulk up, but that they didn’t exhibit the negative side effects (e.g. highly aggressive behaviour, lowered immune response) commonly associated with anabolic steroids.

The new study shows that the squirrels have evolved to have more steroid receptors where they are needed (i.e. in muscle cells) but fewer receptors in other types of cells (e.g. immune cells) that could be negatively affected by the steroids. In this way, they get the benefit of the steroids without the risk.

We heard last year about brain-brain interfaces that used human brain signals t +ScienceSunday movement of other animals (http://goo.gl/W7hyXs)

Now, a recent study published in PLoSOne shows how one person's thoughts can control another person's behaviour.

Sounds like science fiction, but the approach is fairly simple: the thinker wears an electroencephalography (EEG) cap, which measures the electrical signals at the scalp related to different thoughts. The signals are decoded, and sent to a Transcranial Magnetic Stimulator (TMS) system, which applies a magnetic pulse over the part of the motor cortex responsible for moving a finger. When the right signal is sent, the finger moves, and fires a blast in a video game.

We can't decode really complex thoughts yet, but it's away enough to decide binary decisions (like shoot or don't shoot), and voila! You can have someone play the video game for you, by just thinking about it.

Happy Fechner Day!

Psychophysicists around the world rejoice today. Yes, we even make Fechner cakes, and my father has been known to give his lectures in full Fechner garb.

Happy Fechner Day

Today, October 22, is a special day for perception researchers around the world: It is Fechner Day, the day in 1850 that Gustav Theodor Fechner (1801-1887) first conceived of psychophysics - the study of the relationship between physical stimuli and our perception/psychological response to those stimuli.

In the portrait below, vision scientist Nick Wade (Dundee) portrays Fechner within a series of stimulus-response psychometric functions (you can see the image if you look at it from the side, squint, or move away from the screen). Nick developed a series of portraits of vision researchers, appropriately titled Visionaries, others of which you can see here: http://goo.gl/1G8CN

One of the perceptual phenomena that Fechner described was the fact that people can sometimes see faint colours when black and white images move. You can see an example of that in the demonstration at this link: http://goo.gl/mrRJS , which I believe was developed by Mark Newbold. For me, if I set the speed to about 650, and fixate the middle cross, some of the rows seem to be a faint yellow and others a faint blue - different people sometimes report seeing different colours, and the optimal speed/direction may vary for people. The position of the colours can flip when you change the motion direction, and, of course, there really aren't any colours there at all.

So, enjoy, and happy Fechner Day!___Happy Fechner Day!

Jack-o-Lantern Sun

Even the sun is getting into the Halloween spirit, as seen from this +NASA image from earlier this month.

from NASA's site:
Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 Ångströms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.

Frankenpumpkin or Pumpkinstein

Whichever name you prefer, these pumpkins are pretty amazing.

Tony Dighera spent several years and over $400,000 perfecting the perfect way to grow these Frankenstein-shaped pumpkins. Yes, they grow this way, they aren't carved.

He uses a specially designed plastic mold to shape the first few pumpkins on the vine as they grow - the later growing pumpkins get to be too big, so the molding technique doesn't work.

If you're lucky enough to live on the area where these are sold, you can get one for only $100! Perhaps a bit too steep for most of us, but if you've got the cash to spare, and don't want to get your hands all mucky and gooey from carving, at least you've got another option now ;)

One more awesome Halloween tip if you go the traditional carving route: spray paint your pumpkin black before carving. The orange glow from the inside contrasts beautifully with the black shell and makes for a stunningly spooky display.

Gold Nanoparticle Antennae Could Boost Solar Cell Performance
Researchers have created tiny gold antennae that gather and concentrate light in order to increase the efficiency of solar cells by up to ten per cent. Solar cells often don’t absorb very well in the red or infrared part of the solar spectrum. Previous researchers have tried to use gold nanoparticles – which do capture and concentrate light at these frequencies – to boost performance.

The new antennas look more like filaments assembled to form sparse nets and use a much smaller amount of gold –  the building block are clusters of as little as 144 atoms.

The process for making them is simple and inexpensive, and could be used on ordinary silicon solar cells as well as emerging technologies like organic solar cells, which are cheaper but currently limited by low efficiency.

Roots of culture: How chimps learn from each other
It’s long been suspected that tool use in chimps is passed on socially, but a new study catches them in the act and puts a number on the impact.

Researchers observing chimps in Uganda noticed that when one adult male discovered a new way of using leaves and moss to soak up water for drinking, others observing him quickly started using the same tools.

Using simulations of behaviour transmission on the observed social networks, the researchers were able to calculate that each chimp observing the behaviour was 15 times more likely to learn it themselves, while those that simply found discarded tools were not as likely to pick it up.

The findings shed light on how humans developed cultural practices.

DNA signature in ice storm babies
A new study has detected a distinctive signature in the DNA of children born in the aftermath of the 1998 Quebec ice storm.

Five months after the 1998 Quebec ice storm, researchers recruited women who had been pregnant during the disaster and assessed their degrees of distress in a study called Project Ice Storm. Fifteen years later, they found that DNA inside the T cells – a type of immune system cell – of 36 children was modified with a specific pattern of methyl molecules.

This type of DNA modification, called methylation, plays a role in the way the gene express themselves. However the health impacts of these particular changes are not yet known.

This study is the first to show that stress in pregnant women did cause long lasting changes in the genome of their babies.

The highs and lows of marijuana use
A new study helps explain why the same drug can have opposite effects at different doses.

Using a drug that binds to cannabinoid receptors in the brain – the same ones that are activated by cannabis – researchers showed the precise pathway by which low doses stimulate the brain’s dopamine system, which can lead to an emotional response, including fear and paranoia. However, at high doses, the same pathway causes the dopamine system to shut down, blunting emotional responses and leading to apathetic behaviour.

The team also found that other drugs acting on different receptors could prevent these negative responses (i.e., fear/paranoia or apathy). This could offer a safer way for patients who need marijuana for pain to take the drug while reducing the emotional side effects.

Video here: Western University researchers explain the highs and lows of marijuana use

On the origins of the monarch butterfly
Monarch butterflies originated in North America 20,000 years ago at the end of the last glacial maximum before dispersing out to locations around the world, a new study shows.

The authors sequenced the whole genome of 101 monarch butterflies from around the world to better understand the genetic basis of its migration patterns.

The researchers also found that monarch’s distinct bright orange colour is controlled by a single gene not found in any other insects.

Daily Levitation

Every once in a while, someone plusses or comments on a post I made what seems like forever ago, and it always brings a smile to my face.

Today, that smile came from +Giovanni Piliarvu, who reminded me about the awesome photography of +Natsumi Hayashi, and her Daily Levitation series from back in 2011.

She and her photography have come a long way since back then, with loads of publicity and exhibits. But the magic of her images remains, so I had to share it with all of you!

If you want to see the general BTS for her images, it's at her website:

Science Roundup from the Science Media Centre of Canada

David vs. Goliath: How Small Birds Compete
One might think that larger birds invariably win fights with smaller ones, but a new study explains why that is not always the case.

Researchers studied vultures at carcasses, hummingbirds at nectar sources, as well as antbirds and woodcreepers at army ant swarms to discover that some small birds have evolved ways to beat their opponents. These include enhanced maneuverability, new fighting techniques, and more well-developed talons.

David vs. Goliath: How Small Birds Compete
One might think that larger birds invariably win fights with smaller ones, but a new study explains why that is not always the case.

Researchers studied vultures at carcasses, hummingbirds at nectar sources, as well as antbirds and woodcreepers at army ant swarms to discover that some small birds have evolved ways to beat their opponents. These include enhanced maneuverability, new fighting techniques, and more well-developed talons.

The researchers found that the more distantly related the bird species were to each other, the more likely the smaller birds were to win, suggesting that the advantages of large size – at least as far as fighting goes – are more likely to break down over evolutionary time.

Lab-Grown Cells Could Help Combat Heart Disease
For the first time, researchers have grown a type of heart cell called an epicardial cell from stem cells in the lab, an accomplishment that could help in developing new treatments for heart disease.

Epicardial cells form a protective membrane around the adult heart, and during fetal life provide a source of specialized structural cells essential for development and function of the heart. While heart muscle cells have been grown from stem cells before, until now the guiding signals needed to turn stem cells into epicardial cells were unknown.

Researchers are closer to producing functional heart tissue using engineering or 3D printing strategies now that both cell types can be grown. Such tissue could be used to study heart disease, test new drugs and perhaps one day be transplanted into patients to repair damaged hearts.

Water Flowing Upside-down
A new study shows water in certain stretches of the 542-kilometre Fraser Canyon in British Columbia is flowing ‘upside-down’, a discovery that helps explain why the canyon walls remain so steep.

Researchers discovered that high velocity water flows down into deep pools and then upwells along the canyon walls, such that the water along the bottom flowing faster than at the top. They employed a raft-mounted acoustic device that used the Doppler effect from sound waves to determine how fast water flows at various points and depths along the Fraser River.

This is the opposite to most rivers, where the water near the bottom is slowed by friction. The fast-moving flow scours the bottom and sides of the canyon rather than depositing sediment as slower-moving water would; this keeps the cliffs sheer.

The hydraulic study helps us understand the critical role of climate-linked processes like erosion in forming mountain ranges, which in turn affect the climate and soil conditions for those living near them.

Water Found on Neptune-Sized Exoplanet
Astronomers have detected water vapour in the atmosphere of Neptune-sized exoplanet. Previously, it had only been possible to measure the atmospheric composition in large, Jupiter-sized exoplanets.

Using a technique called transmission spectroscopy with which they analysed the light spectrum coming from the exoplanet, they’ve detected water molecules in the atmosphere of HAT-P-11b, an exoplanet with a radius about 4 times bigger than the Earth. This is the smallest exoplanet to date on which researchers have been able to detect water.

Old Drug May Be Key to New Antibiotics
Researchers screening old drugs for new uses have found one that offers a previously untapped strategy for preventing the growth of harmful bacteria.

Many antibiotics work by interfering with the bacterial ribosome, a kind of biochemical workshop where proteins and enzymes needed for the growth of the bacterium are produced. In this case, the team wanted a drug that would prevent the bacterial ribosome from forming in the first place, rather than just mess with its functioning.

The researchers set up an experiment to screen thousands of already-approved drugs for their ability to do this and found one – lamotrigine, currently used an anticonvulsant drug – capable of doing so. The result offers a new strategy to help fight bacterial infections, which could be critical in the face of increasing bacterial resistance to existing antibiotics.

And there can be no spin placed on the ball—that is, it cannot be spinning along an axis other than the horizontal one about which it moves toward the wall. The surface that the ball hits must be completely flat and not able to be moved upon impact. Also, there can be no other external force applied to the ball, as that may change its direction. For example, if a person pushes the ball or a wind gust affects it or the ball hits some bumps on the surface, then its path will change. If any of the conditions are not met, the Law of Reflection cannot be applied to the situation.

communicating research beyond the ivory towers

I'll be speaking Wednesday evening about science outreach and communicating research to the media and to the general public.

Anyone in the Hamilton area, come on by - there will be a lot of time for Q&A, so the more engaged the audience is the better.

They'll be filming the session and posting it on YouTube later, so even if you can't be there in person, you'll still be able to see it. I'll post the link info once that's set up.

Meanwhile, if there are questions you'd like to address to me or any of the panel members in advance, feel free to post them in the comments and I will pass them on to the MC.

We've already got about 6500 users, and people are still learning about it. It's free for every graduate student and postdoc in Ontario, and we're about to open it up to faculty so they can get a better idea how to guide their students, as well as working out a plan to provide global access at no cost to students around the world.

If you check it out, let me know what you think or if you see any bugs/glitches. And if you have ideas for new resources for us to include, just let me know.

Surf's Up!
The art and science of surfing

Having lived in California for 8 years, I have a number of friends who are serious surfers, and it is always great fun to watch them ride the waves. But where do the waves come from? and How do surfers stay on top of them? Physics abounds when it comes to surfing.

Where do waves come from?
A storm affecting a large range of water far out in the ocean for a long time, creates waves of different wavelengths. The longer waves, travel faster than the shorter waves. When the beach is far away from the waves' origin, the more dispersed they will be, creating isolated, nice big waves at the beach. 

How do surfers balance and move?

When the beach is far away from the waves' origin, the more dispersed they will be, creating isolated, nice big waves at the beach. 

How do surfers balance and move?
Gravity pulls you down; buoyancy pushes you up; and the drag force gives friction against your direction of motion. When you're riding the wave, all of the forces balance, and when surfers shift their position on the board, it changes interaction between the gravity and buoyancy forces, allowing you to turn. Then, with luck and a bit of practice, you can realign the forces to regain balance.

+Piled Higher and Deeper (PHD Comics) 's Jorge Cham made a great video a few years describing the formation of the waves and the physics of surfing, while Jorge himself tried to learn to surf. Although he wipes out more than hangs ten, he does a great job of explaining how it all works: http://goo.gl/wMbx65

+Paul Doherty wrote a wonderful piece for the +Exploratorium with even more detail on the physics of waves and surfing: http://goo.gl/cCUs7P

and if you really want the mathematics behind it all, check out this amazing book, The Physics of Ocean Waves (for physicists and surfers), by +Michael Twardos : http://goo.gl/zgfNGS  Because waves are so complex, it is a great introduction to a wide range of topics in mathematics and physics.

Finally, for those of you who just want to see amazingly cool images of surfing and waves from the perspective of someone underwater, check out this wonderful short film by +Morgan Maassen for +National Geographic : A Hypnotic Journey Through Waves and Water http://goo.gl/ptP0la

Can I have 5 minutes of your time to help students succeed?

I'm hoping that everyone who sees this can do me a tiny favour, and check out the website we just launched to provide graduate students and postdoctoral fellows with professional skills training:

http://MyGradSkills.ca

It doesn't matter if you're a graduate student, a graduate from being a student, a high school student, self-educated (everyone on G+ is at least that, and trying to learn more all the time!), or anything else. 

You are all eminently qualified for this!

I'm not looking for in-depth feedback on the topics (entrepreneurship, research skills, career development, etc.). I'm looking for glitches, errors, or anything that just really annoys everyone,*  so we can fix those things up as the site moves forward.

I'm not looking for in-depth feedback on the topics (entrepreneurship, research skills, career development, etc.). I'm looking for glitches, errors, or anything that just really annoys everyone,*  so we can fix those things up as the site moves forward.

I'm also looking for ideas from the general public (that's everyone!) on what else we might include on the site to make it as useful as possible for graduate students and postdoctoral fellows hoping to apply their skills beyond the labs, libraries, and lecture halls of our universities. 

You can also let me know what you like about the site :)  If you visit and don't have suggestions, feel free to just say, "Nice!" or whatever adjective you prefer. 

The more of you who can at least take a quick look, the better. Even just 5 minutes worth of your browsing the site could give me really useful insights into what's working well and what needs to be improved.

Our goal is to make the site as useful as possible for as many people as possible, so feedback is always valuable. Feel free to pass the URL on to your friends too - the more input I can get, the better. 

And, as an incentive to all of you to donate 5 minutes to this worthy project...  *if the website gets enough visits and comments from you guys by Friday, I'll even post the embarrassing Slo-Mo video* of my #icebucketchallenge   :)  

Thanks for your help!!

MyGradSkills.ca
A New Era in Graduate Professional Skills Training

Over the past many months, I've been working busily with a couple hundred colleagues at other universities to create a new way for graduate students to find their future. 

The website launches on today (Monday, September 8, 2014), and we're hoping to start a real revolution in how graduate students and postdoctoral students receive professional skills training. In addition to the initial 18 self-paced, online modules - on topics including teaching and learning, career development, entrepreneurship, and communication - over the coming weeks and months we'll be adding in blogs, virtual career panels, an information clearinghouse, additional modules, and more.

There is also a place for people to give us suggestions for other content they'd like to have, or you can leave your suggestions in the comments below. We'll also be tweeting out from @GPSkills(that's for Grad Pro Skills, not GPS Kills...), using #GradProSkills    to tag posts, and, of course, we're on G+ (+My Grad Skills). If you share anything relevant, be sure to tag us in so we can share it out as well. 

Initially, although the site is open to everyone, the modules will just be available for the ~60,000 graduate students and ~3,000 postdocs in Ontario. As far as we know, that will make it the largest ever Moodle implementation of its kind!

Once we're sure all the bugs are out, we're working to open it to graduate students and postdocs across Canada and around the world.

If you're a graduate student at a University outside Ontario (or outside Canada), and would like to have access, talk to your Graduate Dean (or equivalent) and have them contact us (details on the website).

We're working out a range of membership and partnership options so that we can give access to as many people as possible, with no cost to the students. 

Fingers crossed that everything works!!

*Who created MyGradSkills.ca? 
The Ontario Consortium for Graduate Professional Skills Training is a group of universities from Ontario: McMaster University, Queen's University, University of Guelph, the University of Ottawa, the University of Toronto, the University of Waterloo, and Western University.  The project was funded by the Ontario Ministry of Training, Colleges, and Universities.

Each University took the lead in creating anywhere from 1-4 modules, often working together in the development. The work was a true collaborative effort of hundreds of people over several months, and we hope you’ll make the most of what we’ve created.

Bowling Ball Ballet

I love when my days start and end with science, especially when there some art mixed in with the science.

This post from +Mindy Weisberger meets all those criteria. It is simply mesmerizing to watch the changes in the balls' patterns of movements and perceptual grouping, all falling out of basic principles of physics (with a bit of perception thrown in on the grouping side)

Couldn't agree more with the spectators: Ooooh!! Aaaah!!

Sixteen bowling balls
Swinging from a frame
They move in synch
Then out of synch
Then back in synch again. 

This wonderful video was shared on Facebook by Maria Ikenberry, and her excellent explanation of the pendulum wave is pasted below. 

The "ooh"s and "aaah"s of the spectators are the best part—well, almost. The best part is truly the beauty of physics in action.

From the original Facebook post:

** What am I seeing? How does this work? ** 
The length of time it takes a ball to swing back and forth one time to return to its starting position is dependent on the length of the pendulum, not the mass of the ball. A longer pendulum will take longer to complete one cycle than a shorter pendulum. The lengths of the pendula in this demonstration are all different and were calculated so that in about 2:40, the balls all return to the same position at the same time – in that 2:40, the longest pendulum (in front) will oscillate (or go back and forth) 50 times, the next will oscillate 51 times, and on to the last of the 16 pendula which will oscillate 65 times. Try counting how many times the ball in front swings back and forth in the time it takes the balls to line up again, and then count how many times the ball in back swings back and forth in the same time (though it's much harder to keep your eye on the ball in back!).

** Why are they not perfect at the end? ** 
This large frame is built from wood and is outdoors, which means it expands, contracts, and flexes. Because the position of the frame changes, the cycle lengths are not perfectly aligned. Over time, the minor differences become more pronounced.

** Where is this? ** 
This was built on private property in the mountains of North Carolina (United States), near Burnsville. It is not open to the public.

** Can I get a copy of this video to use in my classroom? ** 
I have uploaded a higher-quality video to YouTube: Pendulum Wave Demonstration
You are encouraged to use this video for educational purposes! If you are sharing online, please provide a link back to this video or the YouTube video. This video is licensed CC BY-SA: http://creativecommons.org/licenses/by-sa/3.0/

** How can I make my own? Where can I learn more? ** 
Here are some links to information about the physics behind this demonstration. There are some small scale versions of this demonstration that can be purchased commercially as well, but if you want a 20’ version like this, you’ll have to make your own! I didn't make this and I don’t have plans for it, but work through the physics at these links and design your own – you’ll learn a lot about physics, math, and construction!

Perceiving Pointillism

Thanks to my +ScienceSunday co conspirator curator +Rajini Rao for an excellent post on the intersection of Art and Science. 

As a vision scientist, I especially appreciate when people can describe the sorts of phenomena we study in such a clear and compelling way.

The Art of Seurat: Science and Pointillism

After winding through the bucolic Dutch countryside, two bus loads of scientists were disgorged at the Kröller-Müller Art Museum in Otterlo, hoping for a dose of culture to leaven our week-long immersion in research (on ATP-driven pumps; http://p-atpases.org/). To our delight, the museum was hosting the work of Georges Seurat, the master of pointillism. Fittingly, Seurat once said, Some say they see poetry in my paintings; I see only science. 

What's the Point?: In contrast to traditional methods that mix pigments, pointillism is a technique where dots of pure color are applied, allowing the eye and the mind to blend the colors to give a richer and brighter effect. Although the term was first used to ridicule the technique, pointillism (also called divisionalism) gained credibility by the end of the 19th century, giving rise to neo-impressionism, cubism and modern art, and influencing other artists like van Gogh and Matisse.  Seurat's most famous work showcasing pointillism is A Sunday Afternoon on the Island of La Grande Jatte – 1884 (http://goo.gl/WXcS48). Estimated to be made up of ~3.5 million dots, it took nearly 2 years to complete!

 A closer look reveals individual dots of blue, green, yellow and even red in the water, which give the impression of changing, shimmering color as the viewer moves towards the canvas. Our brains blend the dots into a color that is not actually there.  When pigments are mixed, they absorb light. By avoiding mixing, there is no subtractive effect and colors appear brighter. The white canvas between dots enhances this effect. 

The inner rings in the animated circles a and b appear to be different colors: pink or orange. But it's just an illusion - revealed when the surrounding circles are stripped away. Notice also that the color surrounding the inner circles in a and c, or b and d, is the same, but the frequency of concentric rings is different, altering our color perception.

Points to Pixels: Never could Seurat have guessed that the principles behind pointillism would be so widely used in modern technology- computer and television screens light up individual pixels colored in RGB (red, green, blue) and printers deposit CMYK (cyan, magenta, yellow, and Key or black) dyes. We are all pointillists now!

Stunning Science

A stunning shot of Cassin's Finch by +Carissa Braun

In her blog post, she notes:

Cassin's finch is a small rosy-tinged songbird found within the mountains of western North America. Though similar in appearance to house finches and purple finches, Cassin's finch is larger with whiter bellies, peaked head shape, and thick, straight-edged bill. Their range and environment also differ with Cassin's finch prefering conifer forests. They are semicolonial with nests sometimes built within close proximity to each other, but often it is only tolerated if nesting time is far enough apart. While their diet is mostly of seeds, insects and fruit are also consumed. They are categorized as a Near Threatened species, but the factors leading to population decline have not yet been identified.

Redefining Our Place in the Cosmic Web

This has to be one of the coolest videos I've seen in a long time. And there is some pretty cool science behind it as well!

#ScienceSunday  

Where are We in the Cosmic Web?
Redefining our place in space within supercluster Laniakea

The +Nature Publishing Group created an amazing video, highlighting the work of researchers from the University of Hawaii, showing that the Milky Way is part of a much larger cluster of galaxies, in what's termed a supercluster. They've named the supercluster Laniakea, which is Hawaiian for immeasurable heaven.  

It's a sort of ironic name, though, since this groundbreaking (spacebreaking?) work is the first time researchers have been able to measure space in a way that shows how the various superclusters divide up, effectively redrawing the boundaries of space and redefining our place in the Cosmic Web.

The video contains some really amazing images and animations, and provides an incredibly clear and concise explanation of the work, so do check it out (it's just a few minutes long, but they make the most of every minute). 

You can read more in Nature News: http://goo.gl/cvao2F , a Nature Editorial: http://goo.gl/pNlVkM , or check out the original article here (behind a paywall): http://goo.gl/Tyst1o

From the article's abstract:

Galaxies congregate in clusters and along filaments, and are missing from large regions referred to as voids. These structures are seen in maps derived from spectroscopic surveys1, 2 that reveal networks of structure that are interconnected with no clear boundaries. Extended regions with a high concentration of galaxies are called ‘superclusters’, although this term is not precise. There is, however, another way to analyse the structure. If the distance to each galaxy from Earth is directly measured, then the peculiar velocity can be derived from the subtraction of the mean cosmic expansion, the product of distance times the Hubble constant, from observed velocity. The peculiar velocity is the line-of-sight departure from the cosmic expansion and arises from gravitational perturbations; a map of peculiar velocities can be translated into a map of the distribution of matter3. Here we report a map of structure made using a catalogue of peculiar velocities. We find locations where peculiar velocity flows diverge, as water does at watershed divides, and we trace the surface of divergent points that surrounds us. Within the volume enclosed by this surface, the motions of galaxies are inward after removal of the mean cosmic expansion and long range flows. We define a supercluster to be the volume within such a surface, and so we are defining the extent of our home supercluster, which we call Laniakea.

Women (and Girls) in Science

My +ScienceSunday co-curators, +Rajini Rao and +Buddhini Samarasinghe, along with Buddhini's HOA co-host, sociologist +Zuleyka Zevallos, have a great blog at nature.com on why there is a gender GAO in STEM fields, and what we can do to bridge the gap.

#ScienceEveryday when it's not #ScienceSunday

Nature vs. Nurture: Girls and STEM

Why is there a gender gap in Science, Technology, Engineering and Mathematics (STEM)? You may have heard the arguments that girls find science “boring,” that their brains are "wired differently", and that attempts to bridge the gender divide “deny human biology and nature”. Attributing the gender gap to biology misses the obvious contribution of societal and institutional biases. Co-authored by +Buddhini Samarasinghe, +Zuleyka Zevallos and me, our article in +nature.com blogs explains how stereotype threats, lack of role models, social conditioning, unconscious bias and institutional practices create an environment where girls feel unwelcome and insecure in STEM fields. We advocate active intervention and go on to discuss effective strategies and practical ways, both simple and sophisticated, to solve the problem. 

Why should we care if girls remain underrepresented in STEM? Apart from basic fairness, if we want our best and brightest working on innovative ideas and creative solutions, it makes little sense to potentially abandon half the population. We already face many hurdles; lack of funding, lack of jobs, and pushback from science denialists backed by populist politics. We need all hands on deck to forge ahead.

We must look to nurture, not nature, for change.

Rapping the Kreb's Cycle
"This is frigging awesoooooome!"

Just in time for the new school year! Biochemistry students looking for a way to learn about the Kreb's (TCA) cycle, have a great mnemonic tool - and a catchy one at that.

Wilson Lam, as a University of Ottawa undergrad, wrote this song as part of a contest in his 3rd year biochem class. He threw in a bit of glycolysis just to spice it up ;)

Lam's lyrics, which he wrote in just a day, since he never expected it to go as viral as it did, are so catchy that I have to put a serious ear worm warning on this one.... Full lyrics are below.

If you'd prefer a less catchy, but also informative Kreb's song, check out Mr. W's song, via the sciencemusicvideos channel: Krebs! (Mr. W's Krebs Cycle Song)

Complete Lyrics (from Lam's post on YouTube, January, 2013):

[Hook]
I'm gonna pop some carbs
Only got a lil' glucose in my pathway
I - I - I'm lazy, lookin' for some CoA
This is frigging awesome

[Verse 1]
Now I got some glucose; hell yeah, I'm in that prep phase
I'm so pumped; doin' work with hexokinase
Glucose to the glucose with a number six phosphate
PGI to that fructose 6-phosphate (dayum)
ATP, ADP, phosphofructokinase E,
1,6-bis, FBP, adolase, two GAP;
GAPDH with some PGK & PGM,
3-P to the 2-Phosphoglycerate, and then
(Enolaaaaaaaassseeee)
PEP to Pyruvate! (glycolysis)

[Verse 2]
FAD, NAD bout to go and grab some hydroG
Pumpin' out all those substrates for some work yeah that's that energy
shuttlin' through that mito-C like nobody's business
what you know about oxidation? biz-NITCH
I'mma do it TCA, I'mma do it TCA
No for real - movin' on - can I have some A-CoA? (thank-you)
Citrate synthase from that CoA to that citrate
Aconitase, step two; isocitrate
I had some NAD+ (plus), I used some NAD+ (plus)
I made some NADH (Hhhhhhhh), and alpha-ketogluterate (oh snap)
dehydrogenase complex, plus some CoA
CO2, NADH out; succinyl CoA
then I take that GDP, add a P (GTP), hold on wait
CoAs gone, people be like "Aw, he got the succinate"

[Hook x2]

[Verse 3]
What you know about intermediary metabolism? (not much)
What you knowin' about what's goin' on in your skin? (uhhhhh)
I'm diggin, I'm diggin, I'm lookin' for some FAD
Step 6, succinate dehydrogenase, that's the key (zing)
Movin' on, reducin' that FAD up to FADH2
fumarate, fumarase that's the enzyme now go shift your gaze
to malate (okay); step 8, malate dehydrogenase
finish off; NADH, oxaloacetate (ahhhhh)

[Hook x2]

[Bridge x2]
That's how Kreb's cycle goes
If you didn't doze now you know
This is how TCA flows
BCH actually doesn't blow

[Hook]

(alpha-ketogluteraaaaaaaaaate)

Music and the Mind

+Sonya Lira popped this back into my stream just in time for #sciencesunday, so I that I'd reshape for those who didn't see it before given that this group has some more great news!! Their amazing LIVE (Large Interactive Virtual Environment) Lab is finished and the official launch is just weeks away!

The space includes a 100 person auditorium in which musicians, actors, dancers all can be wired up to EEG systems to understand how they interact with each other and with the audience - about 30 of whom also can be wired up with EEG and a range of other biological monitoring systems (heart rate, skin conductance, temperature, etc.).

The auditorium is called a virtual environment because any sounds that are played on stage are instantly processed and replayed via speakers so that the acoustics of the room can sound like any auditory environment: Carnegie... more »

Music and the Mind: Boosting Babies Brains

Kudos to my +McMaster University Laurel Trainor, whose group has long been investigating the effects of music on the mind, in babies and beyond. The baby below is wearing an electroencephalography (EEG) cap, like the kind we use in my lab but much tinier!, to measure the electrical responses of the brain to different types of stimuli. One advantage of this type of measure over other brain imaging techniques, like fMRI, is that it enables researchers to determine what's happening in the brain on a really fine temporal scale (although the spatial scale won't be as good as in fMRI - there are always tradeoffs). It's also easier to use EEG with babies because they don't have to stay perfectly still while being tested - and anyone who's been around babies knows that could be a challenge.

In Laurel's most recent study (funded by the Grammy Foundation, CIHR, and NSERC), infants took parts in weekly music enrichment sessions for 6 months, starting when they were 6 months old. One group - the interactive group - sang, moved, and played instruments (shakers, drums, etc.). The other group - the passive group - listened to classical music while playing with random toys. 

At the end of 6 months, the interactive music group showed greater preference for Western musical structure and earlier brain responses to piano tones than the passive music group. Parents also reported more positive social interactions with the interactive group.

Trainor says, "in the first year after birth, infants learn a lot about music, and the particular musical experiences they have may affect their development in a number of ways. Passively listening to music does not have the same effect as actively listening."

It's too early to tell how long these sorts of differences last, or whether they will be significant over the long term for children's development, but parents and kids certainly can have a lot of fun with music regardless ;)

+Sonya Lira popped this back into my stream just in time for #sciencesunday, so I that I'd reshape for those who didn't see it before given that this group has some more great news!! Their amazing LIVE (Large Interactive Virtual Environment) Lab is finished and the official launch is just weeks away!

The space includes a 100 person auditorium in which musicians, actors, dancers all can be wired up to EEG systems to understand how they interact with each other and with the audience - about 30 of whom also can be wired up with EEG and a range of other biological monitoring systems (heart rate, skin conductance, temperature, etc.).

The auditorium is called a virtual environment because any sounds that are played on stage are instantly processed and replayed via speakers so that the acoustics of the room can sound like any auditory environment: Carnegie Hall, a subway station, a wide open field, etc. And as if that weren't enough, the space also includes a disklavier piano - which can record the precise finger movements of a pianist and play a song back exactly as he or she played, and can even be played remotely from another city around the world - and a studio-wide motion capture system to determine how musicians and others move in relation to music.

You can get more information about the lab here: http://livelab.mcmaster.ca

The sky's the limit on what researchers can test in the space, but they are hoping to rest some commercial products (including a smart hearing aid that was developed by the group); to study musical training (related to the study discussed below); to better understand how audiences influence musicians, actors, and dancers; to examine the role of music in a range of health issues; to explore the impact of different types of lecture styles and approaches on student learning and engagement, and just to shed more light on music and the mind.

If anyone is ever in the Hamilton area and wants a tour, just let me know.

Burger King's New Tagline...

In keeping with the Canadian tendency to be as polite as possible and then some, the Burger King + Tim Horton's merger will lead to some changes in the typical BK greeting.
