UCLA researchers develop treatment to reduce rate of relapse complication

Young people with cleft palate may one day face fewer painful surgeries and spend less time undergoing uncomfortable orthodontic treatments thanks to a new therapy developed by researchers from the UCLA School of Dentistry. The treatment incorporates a shiny twist: diamond fragments so small it would take more than 3 million of them to span the diameter of a penny. (more…)

Clever Fish Keep Cool

PORT ARANSAS, Texas — Ocean warming is occurring at such a rapid rate that fish are searching for cooler waters to call home.

A group of international scientists has new evidence that coral reef fish – which struggle to adapt to the warmer ocean temperatures brought about by global climate change – may instead opt to relocate to cooler parts of the ocean. (more…)

Decriminalizing prostitution linked to fewer STDs and rapes

A recently released study found some positive effects in Rhode Island after the state accidentally made prostitution legal for seven years

When the Rhode Island legislature inadvertently decriminalized indoor prostitution in the state from 2003 to 2009, it proved beneficial to UCLA public policy professor Manisha Shah. (more…)

Brain’s response to sexual images linked to number of sexual partners

UCLA researchers say finding could lead to strategies to reduce risky sex

Like most things, sex requires motivation. An attractive face, a pleasant fragrance, perhaps a sexy image. Yet people differ in their response to sex cues, some react strongly; some don’t. A greater responsiveness to sexual cues might provide greater motivation for a person to act sexually, and risky sexual behaviors typically occur when a person is motivated by particularly potent, sexual reward cues.

One-Way Air Flow May Be 270 Million Years Old

Air flows mostly in a one-way loop through the lungs of monitor lizards – a breathing method shared by birds, alligators and presumably dinosaurs, according to a new University of Utah study.

The findings – published online Wednesday, Dec. 11 in the journal Nature – raise the possibility this breathing pattern originated 270 million years ago, about 20 million years earlier than previously believed and 100 million years before the first birds. Why remains a mystery. (more…)

Warm Ocean Causing Most Antarctic Ice Shelf Mass Loss

PASADENA, Calif. — Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent’s ice shelf mass loss, a new study by NASA and university researchers has found.

Scientists have studied the rates of basal melt, or the melting of the ice shelves from underneath, of individual ice shelves, the floating extensions of glaciers that empty into the sea. But this is the first comprehensive survey of all Antarctic ice shelves. The study found basal melt accounted for 55 percent of all Antarctic ice shelf mass loss from 2003 to 2008, an amount much higher than previously thought. (more…)

UCLA life scientists present new insights on climate change and species interactions

UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures.

“There is a growing recognition among biologists that climate change is affecting how species interact with one another, and that this is going to have very important consequences for the stability and functioning of ecosystems,” said the senior author of the research, Van Savage, an assistant professor of ecology and evolutionary biology and of biomathematics at UCLA. “However, there is still a very limited understanding of exactly what these changes will be. Our paper makes progress on this very important question.” (more…)

ANN ARBOR — Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why.

Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms in cold environments—and this genetic program also exists in warm-blooded animals, including humans. (more…)
