... surrender driving. Identification of those unsafe drivers is becoming a serious health priority. Ideally, retirement from driving should occur as close to the optimal time as possible, neither too early, nor too late. Drivers with dementing illnesses often do not recognize that they are unsafe, fail to make...

This is your fly's brain on drugs

... point that drug seeking and taking become central drivers of behavior. While mammalian models are useful for mapping out the neural complexity of these behaviors, insights into the molecular basis of drug abuse can often be garnered from simple models, such as the fruitfly, Drosophila . In the open-acce...

Selective predation and productivity jointly drive complex behavior in host-parasite systems

...and rapid termination of epidemics? The search for drivers of these complex behaviors has become more urgent as epidemics in wildlife populations continue to arise. Recently ecologists have realized that other species may strongly shape disease dynamics. Predators are particularly interesting because they of...

Were bigger brains really smarter?

...d what to whom." The problem is that, whatever the drivers were, they didn't produce a general cleverness that showed up in toolmaking techniques. What's even worse for the bigger-is-smarter-is-better hypothesis, Calvin said, is that after Homo sapiens was walking around Africa 200,000 years ago with a brain...

To train the eye, keep it simple

If athletes, soldiers and drivers must perform every day in visually messy environments, common sense suggests that any visual training they receive should include distractions and disorder. New research from the University of Southern California and UC Irvine suggests common sense i...

Soil fertility in the tropics can be influenced by landscape and precipitation, study finds

...at, while topography and soil age are the dominant drivers of soil fertility in their study area, other factors--such as tectonic uplift, vegetation and climate--are likely to produce a similar patchwork of nutrient availability in the tropics. "Our results indicate that not all old, tropical forests are nut...
