Health Research: One step closer to a new drug for alcohol dependence ♦ 'Paleo' sleep? ♦ Yoga in jails helps make better fathers

One step closer to a new drug for alcohol dependence Researchers might be one step closer to finding an effective drug for alcohol dependence. In two separate studies, they show that the so-called dopamine stabilizer OSU6162 can reduce the craving for alcohol in alcohol dependent people and normalizes the level of dopamine in the brain reward system of rats that have consumed alcohol over a long period of time. However, thorough clinical studies are needed to determine if the OSU6162 also can help alcohol dependent people drink less alcohol. 'Paleo' sleep? Sorry, pre-modern people don't get more Zzzzs than we do It's tempting to believe that people these days aren't getting enough sleep, living as we do in our well-lit houses with TVs blaring, cell phones buzzing, and a well-used coffee maker in every kitchen. But new evidence shows that three ancient groups of hunter-gatherers -- living in different parts of the world without any of those trappings of modern life -- don't get any more sleep than we do. What's behind your thirst? Discovery advances our understanding of how our brain controls body hydration, temperature Scientists have made a breakthrough that advances our understanding of how the brain detects and prevents dehydration. The findings could have important clinical implications, as the key protein they discovered could be a target for the development of treatments and diagnostic tests for many health problems associated with the imbalance of bodily fluids Yoga in jails helps make better fathers Yoga can help fathers in jail be better dads, new research shows. Researchers identify a new culprit behind fibrosis A new molecule has been identified by researchers that involves skin fibrosis, a life-threatening disease characterized by the inflammation and hardening of skin tissue. The new study is the first to investigate the role of this molecule in skin fibrosis and paves the way toward new and improved therapies for the disease. Scientists identify proteins crucial to loss of hearing Posted: 15 Oct 2015 05:34 AM PDT Right now, there is no way to reverse hearing loss, largely because auditory hair cells, which sense sound and relay that information to the brain, do not regenerate. A new study, however, has found a key clue to how these hair cells develop. The study identified a new role for a particular group of proteins in the development and survival of the hair cells.
