Hangouts On Air  - 
 
Hope you can join us on 4/6! RSVP “yes” if you want to add this event to your calendar.
 
Please join us on 4/6 for a Developmental Science HOA with Dr.+Matthew Schlesinger, Associate Professor of Psychology at Southern Illinois University and director of the SIU Vision Lab. Matthew Schlesinger received his graduate degree in cognitive development from the University of California at Berkeley in 1995. After spending a year as a visiting lecturer in psychology at Berkeley, Dr. Schlesinger received a Fulbright fellowship to study artificial life models of sensorimotor cognition with Domenico Parisi at the Italian National Research Council in Rome. Dr. Schlesinger continued his postdoctoral work in 1998-2000 with a multi-disciplinary team of researchers at the University of Massachusetts, studying machine-learning approaches to adaptive motor control.  He is currently involved in three areas of research:  (1) visual attention and spatial working memory in infants, children, and adults, (2) neural network models of early visual processing and oculomotor control, and (3) neural substrates of working memory and spatial-directed attention. 

RSVP “yes” if you want to add this event to your calendar.

+Pierre Labrecque Is your hard drive the same thing as the information stored on your hard drive?  Do you look at pictures of loved ones in raw binary format?  Faith is not mutually exclusive with science, but being contrary without thinking is mutually exclusive with both science and faith.

I actually wandered across this by accident while browsing online. It seemed quite interesting to me that these three words should show up in the same suggestion box. Granted, you can search long enough and any combination of things might show up just due to the sheer amount on the web.

But, at least for me, as a scientist, these three words are all similies. It seems that if someone were to ask me to explain or even anticipate what knowledge we have or will get about the universe I don't think I could answer. But that's what keeps me going.

Now, tear this post to shreds and analyze it for science's sake! :)

white tin becomes the brittle grey tin when cooled below 13 degrees Celsius.
 
white tin or β-tin becomes grey tin or α-tin when cooled below 13 degrees Celsius; the two are allotropic forms of tin.   :)

β-tin (the metallic form, or white tin), which is stable at and above room temperature, is malleable. In contrast, α-tin (nonmetallic form, or gray tin), which is stable below 13.2 °C (55.8 °F), is brittle. α-tin has a diamond cubic crystal structure. α-tin has no metallic properties at all because its atoms form a covalent structure where electrons cannot move freely; alpha-tin is a dull-gray powdery material with no common uses, other than a few specialized semiconductor applications.

Samsung's Smartwatch will Use Your Heartbeats to Unlock Your Smartphone

If you have seen  “SKYFALL”, then you must know how Bond’s gun becomes inoperable when it gets into the wrong hands and saves his life.

What if you find a similar technology in your smartphones?

A recent patent of Samsung  seems to be inspired from Bond’s gun that authenticate a smartphone user from his bio-signals. It is fascinating as it will provide an amazing level of security in smartphone.

Please check the rest of the article from this link- http://www.whatafuture.com/2015/03/17/heartbeat-authentication-in-samsung-smartwatch/

Yes +Matt Cadusch economics is a science. Social science is science. We are a multidisciplinary community where social science is taken seriously, hence it is one of our major community categories. You wrote a one line introduction to a contentious article that calls the science of this report "pseudoscience." The article tries to sully the report by saying it's adopting the "tactics" used by mining companies and business. It turns its nose up at the fact that a consulting firm was hired; and it argues that the data and analysis of the report is mere "guesswork." The author ends on a disparaging note that absolutely attacks the methods and therefore the contribution of the scientists involved: "It's also dispiriting to think that it had to rely on pseudo-science to remind policymakers not to take real science for granted."

We usually delete posts with one sentence introductions because the don't really set a good tone for scientific discussion. We are also set up to critique pseudoscience, junk science and media hype. Both these points are in our community guidelines - please read them.

Bear in mind when you post on contentious science policy issues, we are trying to educate, not reproduce misunderstandings of science. This article does not take seriously the report and the science presented by the Chief Scientist and the Australian Academy of Science. That's a pity given that the general public needs more awareness of the issues we face.

Engineering students extinguish fire with sound

A pair of engineering students created a new type of fire extinguisher that uses sound waves to put out flames.

The prototype extinguisher was developed by computer engineering major Viet Tran and electrical engineering major Seth Robertson of George Mason University in Fairfax, Virginia. The pair hopes their design could revolutionise firefighting, particularly in the home.

The technology is based on the way sound waves displace oxygen as they move through physical space -- oxygen that fire feeds on. If you can suffocate a fire, you can extinguish it, so the pair set to work. They discovered that music is unsuitable -- the sound waves it produces are inconsistent.

A higher frequency sound caused the flames to vibrate, but that was all. The lower frequencies -- 30 to 60 hertz -- seemed to be the so-called "Goldilocks zone" at which the waves were able to effectively keep the oxygen from the flames long enough to suffocate them.

The next step was the development of a portable, handheld extinguisher. DARPA's device, for example, was a large machine that can't be easily moved around. The prototype they developed consists of the sound frequency generator, a small amplifier, and a collimator made out of a cardboard tube with a hole at the end, to focus the waves in a specific direction.

This device was able to extinguish small, controlled fires created with an alcohol accelerant, proving that the concept is viable. Of course, the next step is further development.

If you’ve ever seen objects under a blacklight – like clothes or highlighters – you may have noticed that some things glow when they’re hit by that kind of light, and others don’t.

Interesting... However algae already have a high oil content the issue is more to produce the amount of algae...

And for other products the product can easily be contaminated with heavy metals...

My partner company actually has the technology to produce highest algae yealds with extremely high homogenicity and basically zero contaminants

Medieval medical texts may hold keys to modern battle with anti-microbial resistance.
 
Scientists were "astonished" to find that a treatment for eye infections found in the 1,200 year old Bald's Leechbook almost completely wiped out the modern MRSA superbug.

"What Is the Evidence for Evolution Found in the Fossil Record? Richard Dawkins Speech (2009)."

The evidence for evolution is overwhelming.  This video features famous atheist, intellect, and evolutionary biologist Richard Dawkins as he speaks about the evidence for evolution, and how astounding and wonderful the phenomenon of life derived from it truly is.

Video duration:  1 hour 25 minutes.

From the video's description...

-----
The Greatest Show on Earth: The Evidence for Evolution is a 2009 book by British biologist Richard Dawkins, which was released on 3 September 2009 in the UK and on 22 September 2009 in the U.S. It sets out the evidence for biological evolution, and is Dawkins's 10th book, following his bestselling critique of religion The God Delusion (2006) and The Ancestor's Tale (2004), which traced human ancestry back to the dawn of life.

Richard Dawkins has written a number of books about evolution, beginning with his first two titles The Selfish Gene (1976) and The Extended Phenotype (1982). These were followed by three books which attempted to clarify some common misunderstandings about evolution. His recent documentary series The Genius of Charles Darwin looks at Darwin's life and some of the evidence for evolution. Despite these works and others, he felt that there was a 'missing link' in that he had never comprehensively addressed the evidence of common descent. Dawkins believed that opposition to evolution at the time of writing the book was as strong as ever, despite overwhelming and still growing evidence for the theory. He wrote the book in his final months as Charles Simonyi Professor for the Public Understanding of Science (Marcus du Sautoy now holds the position) and finished it in retirement. He thought that 2009, the bicentennial of Darwin's birth and 150th anniversary of his book On the Origin of Species, was the perfect time for such a work. Other authors have written similar books recently, such as Jerry Coyne's Why Evolution is True which Dawkins highly recommends.

The book is divided into 13 chapters spanning over 400 pages, and includes an appendix called "The History-Deniers" in the end material.
Only a Theory? (Nature of scientific theory and fallibility)
Dogs, Cows and Cabbages (Artificial Selection)
The Primrose Path to Macro-Evolution
Silence and Slow Time (Discusses the Age of the Earth and the Geological Time Scale)
Before Our Very Eyes (Examples of Evolution Observed)
Missing link? What do you mean, 'Missing'? (the fossil record)
Missing persons? Missing no longer (Human Evolution)
You did it yourself in nine months (a statement attributed to J. B. S. Haldane; discusses developmental biology)
The ark of the continents (biogeography and plate tectonics)
The tree of cousinship (the tree of life, homology and analogy)
History written all over us (vestigiality and unintelligent design)
Arms races and 'evolutionary theodicy' (coevolution and evolutionary arms races)
There is grandeur in this view of life (based on the final passage of On the Origin of Species)

This is something that is worth mentioning. Biohackers just showed what science and biology can do. Even though this enhanced vision capability is temporary it is no less than a superpower. Well it also sends a message science is for everyone. Remember Science for the Masses group work out a garage.

Chronic Pain - Understanding the Underlying Mechanism

Pain is an important sensor of human physiology as it is one of the first indicators of something going wrong but when the pain is chronic then it can be hard to live with. Chronic pain patients are mostly misdiagnosed as we don't know much about mechanism and what really triggers the chronic state. Latest study suggest that problem may lie in over activation of neuron in gyrus cinguli region of brain. Neurons get over sensitive to pain stimulus and remain in continuous state of excitation leading to chronic pain. Scientist further explored that over sensitivity of the neurons are due to downregulation of ion channel leading to over activation of neuronal stimulus.
"It has been known for some time that serotonin can modulate pain perception and the function of some drugs is based on this. Nevertheless, what is new in our study now is that we were able to identify a specific subtype of serotonin receptor that reduced the perception of pain more efficiently. This is an important result, which might help to treat chronic pain more efficiently in the future."
