Two chemicals boost immune cells' ability to fight HIV without gene therapy

...otective functions. The massive amount of division prematurely shortens these cells' ends, or telomeres, ultimately exhausting the immune system. UCLA's previous research shows that telomerase rejuvenates the telomeres and allows the immune cells to remain youthful and active as they replicate under HIV's attac...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

... million people, primarily women and children, die prematurely each year worldwide (400,000 in sub-Saharan Africa) from respiratory diseases caused by the pollution from such fires, according to previous studies by the researchers.

A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

...e pattern of white noise caused more eggs to hatch prematurely than did the rain-like white noise. "These experiments don't rule out the possibility that the frog eggs use other cues," she says. "But clearly, differences in temporal patterns are enough to affect the perception of how dangerous a disturbance is."...

For the current study, they created a second strain of mutant mice in which the Klotho gene generated more of the protein than in normal mice. Those mice lived between 19 percent to 31 percent longer than normal mice. The res...

While many congenital defects can be safely repaired after birth, Fauza's goal is to fix tracheal defects in utero. Once the baby is born, tracheal surgery requires that the baby be intubated and ventilated long after the opera...

Womb needed for proper brain development
