Natural homophobes? Evolutionary psychology and antigay attitudes

Consider this a warning: the theory I’m about to describe is likely to boil untold liters of blood and prompt mountains of angry fists to clench in revolt. It’s the best--the kindest--of you out there likely to get the most upset, too. I’d like to think of myself as being in that category, at least, and these are the types of visceral, illogical reactions I admittedly experienced in my initial reading of this theory.

Polar Ice Sheets Melting Faster Than Predicted

Ice loss from the massive ice sheets covering Greenland and Antarctica is accelerating, according to a new study. If the trend continues, ice sheets could become the dominant contributor to sea level rise sooner than scientists had predicted, concludes the research, which will be published this month in the journal Geophysical Research Letters

Beautiful Minds: Imaging Cells of the Nervous System [Slide Show]

In the March issue of Scientific American Carl Schoonover, author of Portraits of the Mind: Visualizing the Brain from Antiquity to the 21st Century , describes a new computer-modeling technique that allows researchers to zoom in on the smallest components of the active brain in 3-D. To accompany the story, we've collected images from his recent book , which describes the tools that scientists have used to observe the nervous system from the second century to the present.

Signals in a Storm: Seeing Brain Cells Communicate (preview)

If you could pause time for an instant and make yourself small enough to discern individual molecules, the far right of this image is what you might see when one brain cell communicates with another across a synapse--the point of contact between two nerve cells. How the brain senses, thinks, learns and emotes depends on how all its nerve cells, or neurons, communicate with one another. And as a result, many laboratories are working feverishly to understand how synapses function--and how psychiatric drugs, which target them, improve patients’ lives

Short on sleep, brain optimistically favors long odds

Sleep deprivation can lead to plenty of unwise decisions, which researchers have long tied to flagging attention and short-term memory . But a new study shows how just one night of missed sleep can make people more likely to chase big gains while risking even larger losses--independent of their tapering attention spans. [More]

Science in the Neighborhood: how to make a really good coffee

Sitting at the end of the long wooden bar, I watch with curiosity as Richie begins his pour. He starts the stopwatch on his cell phone and proceeds to pour steaming hot water over the coffee grounds in a precise choreographed motion
