The wave of protests sweeping across the Middle East and North Africa has been described as revolutionary. Whether this is an accurate description of what is taking place remains to be seen, and depends upon how you define a revolution....... Read more »

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 (

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?

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 »
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 »

Oceanographer Robert Ballard’s literary showpiece The Discovery Of The Titanic today sits on a shelf in my bedroom collecting dust.

I had dismissed [...]... Read more »

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 »

As the Northeast of the United States was hammered by thundersnow this week, students, parents and perhaps those working from home had the opportunity to indulge in outdoor winter activities. For many, being in the snow again is losing its luster. As an Associated Press article noted, “The Northeast has already been pummeled by winter [...]

As most of us know, a cancer cell is formed when its DNA becomes altered, either by the switching on of genes which allow uncontrolled proliferation, or by the switching off of the genes which prevent this from happening.

Ingestive behaviour is largely governed by two biological systems: the homeostatic system involving hunger and satiety and the hedonic system involving appetite and reward.
The latter system is also involved in other hedonic behaviours ranging from alcohol and recreational drug use to other “pleasurable” activities like sex, shopping, or gambling, all of which can manifest themselves [...]... Read more »

Typically, when we think of Tyrannosaurus Rex, we envision a giant killing machine with titanic jaws and huge teeth that could crunch through bones as thick as our arms and legs.

"Some patients, even with significant doses of medication, still continued to verbalize significant amounts of pain."
Just giving more is not always an option. Maybe there are restrictions in the protocol. Maybe the patient's vital signs change in a way that suggests that more medication is not the best idea at that time.

Sexual assault is no laughing matter - unless, of course, the would-be rapist isn't human. Who doesn't giggle when they see a small dog humping someone's leg?
