Researchers describe mechanism that underlies age-associated bone loss

Fri, 22 Sep 17 00:08:00 -0700

A major health problem in older people is age-associated osteoporosis -- the thinning of bone and the loss of bone density that increases the risk of fractures. Researchers have now detailed an underlying mechanism leading to that osteoporosis. When this mechanism malfunctions, progenitor cells stop creating bone-producing cells, and instead create fat cells. Knowledge of this mechanism can provide targets in the search for novel bone-loss.

Many research groups have explored human adaptation to high altitude living among three major far-flung global populations: Tibetans, Ethiopians and Peruvians. But few have simultaneously explored the other extreme---maladaptation----in the form of chronic mountain sickness (CMS). Now, in the largest whole genome study of its kind, an international research team led by University of California San Diego's Chairman of Pediatrics, Dr. Gabriel Haddad, has expanded on their recent study of understanding both adaptation extremes in a Peruvian population.

Touching helps build the sexual brain

Thu, 21 Sep 17 00:13:10 -0700

Hormones or sexual experience? Which of these is crucial for the onset of puberty? It seems that when rats are touched on their genitals, their brain changes and puberty accelerates. In a new study publishing Sept. 21 in the open access journal PLOS Biology researchers at the Bernstein Center, and Humboldt University, Berlin, led by Constanze Lenschow and Michael Brecht, report that sexual touch might have a bigger influence on puberty than previously thought.

Synthetic molecule 'kicks and kills' some persistent HIV in mice

Thu, 21 Sep 17 00:13:00 -0700

Scientists have designed a synthetic molecule that can reactivate dormant human immunodeficiency virus (HIV) in mice and lead to the death of some of the infected cells, according to a study published in PLOS Pathogens.

Dancing electrons lose the race

Thu, 21 Sep 17 00:12:40 -0700

Why poison frogs don't poison themselves

Thu, 21 Sep 17 00:11:30 -0700

Poison frogs harbor some of the most potent neurotoxins we know, yet scientists have long wondered -- how do these frogs keep from poisoning themselves? With a new paper published in the journal Science, scientists are a step closer to resolving that head-scratcher. And the answer has potential consequences for the fight against pain and addiction.

If at first adults don't succeed, babies are more likely to try, try again
