Will the uprising in the Middle East & North Africa usher in a new era of science and innovation in the Arab world?

by Farooq Khan in Complex systems + science

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 »

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?

Bonding, Biophilia, and Biosynergy--oh my!

by Serious Monkey Business in This is Serious Monkey Business

Growing up, I never gave so much of a guenon's dung for primates. But after one class and some research, I think about the effects of bonding with primates and what effects that has on the environment.... Read more »

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

by Robert Deyes in Promega Connections

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

by Brian Switek in Dinosaur Tracking

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 »

Snow fleas: helpful winter critters

by Katie Kline in EcoTone

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 [...]

Tiny fish light the way to fighting cancer

by Wellcome Trust in Wellcome Trust Blog

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. What is unknown however, is the role that the innate immune system plays in the development [...]... Read more »

Opiate Receptor Gene Promotes Sweet Tooth

by Arya M. Sharma in Dr. Sharma's Obesity Notes

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 »

Simply Resisting Persuasion: Digressing

by Doug Keene in The Jury Room

We’ve been doing our series on Simple Jury Persuasion for a while now and thought it might also be good to illustrate some of the most common ways we see people trying to resist persuasion (and then provide you ways to counter their resistance.  Researchers (and even popular writers) have studied this topic for years.

scavenger or predator, the great t. rex debate

by Greg Fish in weird things

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. Or, if you’re a fan of Jack Horner, you’re probably thinking of a five ton scavenger roaming the badlands and terrifying every smaller predator [...]... Read more »

Etomidate in procedural sedation

by Rogue Medic in Rogue Medic

"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.

Reverse Bestiality: When Animals Commit Sexual Assault

by Christie Wilcox in Observations of a Nerd

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? But what many people don't realize is that reverse bestiality - where an animal makes unwanted sexual advances on a person - is a true problem for scientists working in the field where the actions of wild animals are completely unpredictable....

Better genomics through chemistry

by Becky in It Takes 30

There’s been a little flurry of papers from UCSF recently about using chemical and environmental perturbations to ask when and why you need the function of a particular gene.  I originally thought I might try to write about all of them at once, but no — there’s more here than I can do justice to [...]...
