Brain scans could help doctors predict adolescents’ problem drug use before it starts There’s an idea out there of what a drug-addled teen is supposed to look like: impulsive, unconscientious, smart, perhaps – but not the most engaged. While personality traits like that could signal danger, not every adolescent who fits that description becomes a problem drug user. So how do you tell who’s who? There’s no perfect [...]
What do your co-workers really think of you? Everyday in the workplace, colleagues actively compete for a limited amount of perks, including raises, promotions, bonuses and recognition. But new research from Washington University in St. Louis shows that, more than often than not, people fall short in determining which co-workers might be trying to edge them out on the job. “We looked at [...]
Uncertainty perception drives public’s trust, mistrust of science Many policies — from medicine to terrorism — depend on how the general public accepts and understands scientific evidence. People view different branches of sciences as having different amounts of uncertainty, which may not reflect the actual uncertainty of the field. Yet public perceptions determine action, allocation of funding resources and the direction of public [...]
Tiny fibers open new windows into the brain For the first time ever, a single flexible fiber no bigger than a human hair has successfully delivered a combination of optical, electrical, and chemical signals back and forth into the brain, putting into practice an idea first proposed two years ago. With some tweaking to further improve its biocompatibility, the new approach could provide [...]
Top students more likely to smoke pot, drink alcohol Academically gifted teens are more likely to drink alcohol and smoke pot compared with teens with lower test scores.
Bad hospital design is making us sicker Research supports an urgent need to change the way we build, maintain and work in hospitals, and many facilities could do more to promote rest and healing while preventing stress and infection.

Researchers uncover brain circuitry central to reward-seeking behavior Scientists have found that as mice learn to associate a particular sound with a rewarding sugary drink, one set of prefrontal neurons becomes more active and promotes reward-seeking behavior while other prefrontal neurons are silenced, and those neurons act like a brake on reward-seeking.
Scientists survey the state of sleep science Sleep remains an enduring mystery with major clinical relevance, according to a a recent review. In recent decades, new technologies have allowed neuroscientists to identify multiple brain circuits that govern the sleep/wake cycle, as well as the factors that can influence it, such as caffeine and light. But the brain's complexity is still a stumbling block in understanding this ubiquitous and necessary animal behavior.
Brain-machine interfaces: Bidirectional communication at last A prosthetic limb controlled by brain activity can partially recover the lost motor function. Neuroscientists asked whether it was possible to transmit the missing sensation back to the brain by stimulating neural activity in the cortex. They discovered that not only was it possible to create an artificial sensation of neuroprosthetic movements, but that the underlying learning process occurs very rapidly. These finding were obtained by resorting to imaging and optical stimulation tools.
Itch neurons play a role in managing pain There are neurons in your skin that are wired to sense itchy things. These neurons are separate from the ones that detect pain, and yet, chemical-induced itch is often accompanied by mild pain such as burning and stinging sensations. But when it comes to sending signals toward your brain through your spinal cord, itch and mild pain can go through the same set of spinal cord neurons.
