More targeted efforts are needed from both the public and private insurance sectors in order to encourage people to take action to reduce their risk of flood damage, according to a new study of three European countries.
Having friends who smoke doubles the risk that youth ages 10 to 19 will pick up the habit, finds new meta-analysis of 75 longitudinal teen smoking studies. This influence is more powerful in collectivistic cultures than in individualistic ones.
Scientists have been able to accurately estimate an individual's age from their brain structure. The researchers found that significant microstructural changes occur in the brain from early to mid-adulthood. Until now, scientists thought that brain structure was relatively stable during this period of life, and this is one of the first studies to show that our brains continue to change throughout our early and mid-adulthood.
Gut microbes have been in the news lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism. But just how do they communicate with the brain? Results from a new study suggest a pathway of communication between certain gut bacteria and brain metabolites, by way of a compound in the blood known as cortisol. And unexpectedly, the finding provides a potential mechanism to explain the characteristics of autism.
Suicide rates in rural areas of Maryland are 35-percent higher than in the state's urban settings, a disparity that can be attributed to the significantly greater use of firearms in rural settings, according to new research.
Decades of research has shown that apes, in spite of their proverbial aping abilities, are rather poor imitators, especially when compared to human children. Current theories hold that apes are worse imitators because they lack this social and communicative side of imitation. A new study has instead targeted the interactive side of imitation directly, and finds that the divide between humans and chimpanzees is less clear cut.
Substance abuse is a continuing problem in the US, to the point of being an 'epidemic.' Treatments exist, but far too often patients relapse with devastating impacts on themselves and those around them. Now, scientists report that they have made progress toward a vaccine against the effects of fentanyl, a synthetic opioid, in combination with heroin.
A new preclinical study found that a brief period of extended wakefulness before surgery enhances pain and prolongs recovery time after surgery. Caffeine administration helped to reduce the harmful effects of sleep loss on subsequent surgical pain.
Most of the events that led to sustained prescription opioid use were not hospital events and associated procedures, but diagnoses that were either nonspecific or associated with spinal or other conditions for which opioid administration is not considered standard of care, according to a new study.
The human brain has a region of cells responsible for linking sensory cues to actions and behaviors and cataloging the link as a memory. Cells that form these links have been deemed highly stable and fixed. Now, new research conducted in mice challenge that model, revealing that the neurons responsible for such tasks may be less stable, yet more flexible than previously believed.
