Kids vs Psychiatrists: Final score 1-0

by Lorax in Angry by Choice

By now many have heard about the recent study published in Pediatrics which, of course, shows a clear link between extensive video game playing and depression in teenagers. You may have also heard about another recent publication of a study conducted by 8-10 year olds.

"How are these studies related?" You may ask.

"They are not." I may respond. Actually I will respond. These studies have nothing to do with each other. However, they are related from the perspective that they are BIG news!

Taking flight on light

On occasion, a scientific idea comes along that is so simple and elegant that one wonders that it hadn’t been done before!  Such is the case with the results of an article published online in Nature Photonics in December, which … Continue reading →... Read more »

Uninvited (but very cool) houseguests – Guest Post

by Morgan Jackson in Biodiversity in Focus

Today’s special guest blogger is Jess Vickruck, a PhD candidate at Brock University. Jess studies twig nesting bee diversity and the impacts of nest choice on their biology. When I first started my master’s project, my intention was to look at how nest choice affected fitness in twig nesting carpenter bees (genus Ceratina, family Apidae).  [...]... Read more »

What is the objective?

by Jason Collins in Evolving Economics

An economist typically bases their economic models on an assumption that the economy is composed of agents who gain utility from consumption. From the beginning of the model, they take consumption  to be the objective and all decisions by the agents aim to maximise their level of consumption within the budget constraint that they face. While I recently posted on how most economists’ fixation on [...]... Read more »

Premature Brain Diagnosis in Japan?

by Neuroskeptic in Neuroskeptic

Nature has a disturbing article from their Asian correspondent David Cyranoski: Thought experiment. It's open access.In brief: a number of top Japanese psychiatrists have started offering a neuroimaging method called NIRS to their patients as a diagnostic tool. They claim that NIRS shows the neural signatures of different mental illnesses.The technology was approved by the Japanese authorities in April 2009, and since then it's been used on at least 300 patients, who pay $160 for the privilege. ........

Test the Waters, but Don’t Assume that Bias is Forever: Deepwater Hasn’t Translated to Deep Trouble for Energy Defendants

by Persuasion Strategies in Persuasive Litigator

By: Dr. Shelley Spiecker Six months after the public was riveted to press coverage of the oil spill in the Gulf, impact on energy defendants has been less doomsday than feared. In fact, this is one of the better times in the past 10 years to be an energy defendant in front of a jury. Why? Much as the spill itself appeared to dissipate more rapidly than expected, the tide of public opinion has drifted away from concern over the environmental practices of energy companies, and toward concern over ........

100 calorie mini snack-packs: helpful for calorie control or just excess packaging?

by Peter Janiszewski, Ph.D. in Obesity Panacea

I absolutely love it when I wonder about something I encounter in my daily life, and then I find the answer to this quandary provided by peer-reviewed research.
Oh, how I love science.
But, I digress.
For a few years now countless food manufacturers have been “sub-packaging” their foods into smaller portions in an apparent effort to curb folks from overindulging. You can usually find 100 kcal multi-packs of chips, pretzels, chocolates, and all sorts of junk foods. Despite the very obvious ne........ Read more »

Dark Matter Reconstruction From Radio Experiments.

by Joseph Smidt in The Eternal Universe

As photons move through the universe they get gravitationally lensed as the pass by large clumps of matter. (As shown in the image above.) Dark matter, being the dominant form of matter, lenses these photons more than anything.  Therefore, by studying the lensing properties of incoming photons, in principle we can reconstruct what the profiles of the dark matter doing that lensing.

Now, put (

Mathematicians and Mongeese: Peeing to Defend Territory? or Mates?

by Jon Wilkins in Lost in Transcription

So, you may have heard about Tihomir Petrov, the math professor at Cal State, Northridge who was arrested for urinating on his colleague's office door. Campus security got video footage of Petrov in the act when they set up video cameras following the discovery of "puddles of what they thought was urine."

You may be asking yourself, what the heck was this dude thinking? How should we interpret the behavior of this Homo mathematicus (not that there's anything wrong with it) specimen?

NGS and the Hallmarks of Cancer

by Daniel Koboldt in Massgenomics

Massively parallel sequencing will be applied to hundreds or thousands of tumor genomes this year. Catalogues of somatic alterations in human cancers (e.g. COSMIC) will grow, perhaps as exponentially as dbSNP did in the past decade. Perhaps more importantly, we will begin to see cases where whole-genome or whole-exome sequencing of a patient’s tumor guides [...]... Read more »

The Saga of Landau-Gauge Progators: A Short History

by Marco Frasca in The Gauge Connection

I have never discussed too much in-depth the history of the matter of Yang-Mills propagators in Landau gauge even if I often expressed a clearcut position. This is a kind of disclaimer when I say that I would not like to offend the work of anyone but my results agree excellently well with lattice computations [...]... Read more »

Metal Eaters Propel The Demise Of The Titanic

Oceanographer Robert Ballard’s literary showpiece The Discovery Of The Titanic today sits on a shelf in my bedroom collecting dust.  Gone are the days when it was heavily leafed through by relatives and close friends mesmerized as they were by the glossy pictures and personal accounts of disaster contained within its covers.  I had dismissed [...]...

STS-51L Challenger Tragedy | 25 Years Today

by Michael Lombardi in a New Life in the Sea

Twenty-five years ago this very morning (at age 6) I was sitting on a tile floor in the hallway of Martin Elementary School in Seekonk, Massachusetts watching history unfold in real-time. This school assembly followed a series of classroom lessons about space - our solar system, the moon, and exploration.
As the world turns, it often takes tragedy to so well ingrain lessons to be learned, and this case was no exception. As I sat there with three classrooms worth of schoolmates, I watc........ Read more »

Teratophoneus: Utah’s Monstrous, Murderous New Tyrannosaur

It missed the 2010 Utah dinosaur rush by nearly a month, but a new tyrannosaur from the southern part of the beehive state makes up for its tardiness by helping to fill a gap in the famous group’s evolutionary history. Almost one year ago, paleontologists Thomas Carr and Thomas Williamson described Bistahieversor sealeyi, a tyrannosaur [...]... Read more »
