Well-traveled wasps provide hope for vanishing species
They may only be 1.5mm in size, but the tiny wasps that pollinate fig trees can travel over 160km in less than 48 hours, according to research from scientists at the University of Leeds. The fig wasps are transporting pollen ten times further than previously recorded for any insect. view more (2009-11-10)
Mom was right: Nice guys don't always finish last
Picture it: One jerk in a bar spends the night delivering bad come-ons to women. By the end of the evening, the women aren't receptive to even the nicest guys around. view more (2009-11-06)
Single-stranded DNA-binding protein is dynamic, critical to DNA repair
Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth along single-stranded DNA, gradually allowing other proteins to repair, recombine or replicate the strands. view more (2009-10-22)
MIT neuroscientists find neural stopwatch in the brain
MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. view more (2009-10-20)
Paradigm shift needed to combat drug resistance
When people travel, bacteria and other infectious agents travel with them. As about a billion people cross international borders each year, many more billions of the bugs come along for the ride. view more (2009-10-16)

Can an over-the-counter vitamin-like substance slow the progression of Parkinson's disease?
Rush University Medical Center is participating in a large-scale, multi-center clinical trial in the U.S. and Canada to determine whether a vitamin-like substance, in high doses, can slow the progression of Parkinson's disease, a neurodegenerative disorder that affects about one million people in the United States. view more (2009-09-22)
Flips, flops and cartwheels
Geckos and other lizards have long been known for their incredible ability to shed their tails as a decoy for predators, but little is known about the movements and what controls the tail once it separates from the lizard's body. view more (2009-09-09)
Environmental effects of cold-climate strawberry farming
Strawberries are America's fifth-favorite fruit, according to consumption rates. California and Florida grow more than 95% of the nation's strawberries; an additional 12,000 acres are planted in other states. view more (2009-09-08)
New study suggests the brain predicts what eyes in motion will see
When the eyes move, objects in the line of sight suddenly jump to a different place on the retina, but the mind perceives the scene as stable and continuous. view more (2009-08-26)
Abnormal Brain Circuits May Prevent Movement Disorder
Most people who carry a genetic mutation for a movement disorder called dystonia will never develop symptoms, a phenomenon that has puzzled scientists since the first genetic mutation was identified in the 1990's. view more (2009-08-06)

US-Mexico border wall could threaten wildlife species
A 700-mile security wall under construction along the United States' border with Mexico could significantly alter the movement and "connectivity" of wildlife, biologists say, and the animals' potential isolation is a threat to populations of some species. view more (2009-07-08)
