by SAGE Insight in SAGE Insight

How US strategic antimissile defense could be made to work From Bulletin of Atomic Scientists Contrary to a new nuclear strategy adopted by the US government in April 2010, that relies on assumptions that the current missile defense systems will reliably protect the continental United States in the extreme circumstances of nuclear-armed combat, now research [...]...

Gaming used for teaching psychopharmacolgy

by Dr Shock in Dr Shock MD PhD


Teaching psychopharmacology to med students can be very dull. Often tried ways of teaching this subject were through lectures or in smaller groups during seminars. At the University of Minnesota Medical School they tested the use of gaming compared to the ordinary lectures. The study was conducted during a 6-week psychiatry clerkship of third year [...]

Breathe deep?

by PalMD in White Coat Underground

Winter has come to the Great Lakes, no matter what the calendar says.  This morning I walked out the door to take out the trash and the cold took my breath away.   I warmed up the car while I had breakfast, perhaps not the most environmentally friendly practice, but… On my way to work, depending [...]...

Pouches, pockets and sacs in the heads, necks and chests of mammals, part VI: guttural pouches, false nostrils and preorbital fossae in horses, tapirs and rhinos

by Darren Naish in Tetrapod Zoology



Back to the series on pouches, pockets and sacs (for previous articles see links below). The previous article finished by looking at the guttural pouches present in the Mongolian gazelle Procapra gutturosa. This links us nicely to the select group of mammals - perissodactyls, hyraxes, bats and rodents - that possess air-filled structures (called guttural pouches) located in the upper respiratory tract, pressed up close to the tympanic region at the back of the skull. In this article, I'm only ........ Read more »

Another Gender Gap Closed by a Well-Timed Bit of Encouragement

by David Berreby in Mind Matters


Last summer I described how psychologists at Rutgers closed the usual gap between higher boys' and lower girls' scores on high-school chemistry tests. When the students used a textbook whose pictures depicted only women scientists, the girls outscored boys. A few days ago, this paper in Science ...Read More

Saturn’s rings get spontaneously shaken up

Let there be Light !... Bioluminescence part 2

by DefectiveBrayne in The Defective Brain

The roles that bioluminescence plays in the lives of organisms today is fascinating. How did this trait evolve? This is a complex question, because bioluminescence is believed to have evolved around 50 different times in different species of animals.
So how do living creatures produce light? Well, the actual question that needs to be asked is how do living creatures produce visible light.

Economics and Inequality

by Julian Friedland in Business Ethics Memo

Cornell Economics and Management Professor Robert R. Frank draws attention here to the disconnect between economic research and ethical thinking, specifically on the notion of growing US inequality:"Economists who say we should relegate questions about inequality to philosophers often advocate policies, like tax cuts for the wealthy, that increase inequality substantially. That greater inequality causes real harm is beyond doubt."It's refreshing to hear this criticism from an economics and ........ Read more »

Vaccinating the Billion-Brain Parasite

by Rob Mitchum in ScienceLife

If a parasite infected the brains of 2 to 3 billion people, up to one-half of the world’s population, one would probably consider it a pretty serious public health emergency. But such a situation already exists, with the parasite Toxoplasma gondii, the cause of the disease toxoplasmosis. The parasite is the most common infectious cause [...]... Read more »

A Role for Prions in Alzheimer’s Disease?

Three-dimensional configuration of a prion protein. Left = normal folding. Right = protein with the disease-associated amyloid folding. Source.

Teen Driving and Fatal Crashes

by William Yates, M.D. in Brain Posts

Reducing motor vehicle accident rates and deaths in the teenage population is a public health priority.  Efforts to reduce the rates of fatal injuries in young drivers include graduated driving license privileges and reduced legal blood alcohol for teen drivers.  States have variable legal BAC generally any level or a level below 0.01 or 0.02 g/dL compared to .08 to 1.0 g/dL for adults.  Additionally, the hazard related to using a telephone and texting while driving is significant........

Is My Child Behind in His Development?

by Brandon in Notes on Parenting

By BrandonDevelopmental Milestones: Fact or Myth?As parents, we are almost constantly comparing our child to someone else's child (or even to our own children who have already gone through that phase of life), and there always seems to be something to fret about. Are you worried that your child isn't saying enough words yet, or isn't walking and he's already a year old? These are common concerns, especially for new parents.

In my undergraduate and graduate training (and as a parent) I have lear........ Read more »

The Evolutionary Roots of Talking With Our Hands

by Krystal D'Costa in Anthropology in Practice



Human and bonobo ape hands. © SPL

New Yorkers are hand talkers—we often use gestures to add emphasis to our conversations. Whether we're pointing to direct tourists, or waving to demonstrate our exasperation with traffic, drivers, or pedestrians, or trying to interject (New Yorkers don't interrupt!) we're gesticulating. We're not the only ones to do this, of course, but in my experience we do tend to employ this element of communication fairly frequently.
The role of gestures in communicat........ Read more »
