HIV Patients May Be at Risk of Heart Problems When Taking Protease Inhibitor Drugs

...events are serious side effects in drugs, but with extra caution from physicians, this risk that we've identified can be managed, and that's the good news."

Critical role in programmed cell death identified

...ocked survive, at least in the lab, with their 131 extra cells. Such studies are impractical in mammals because cell death is essential and animals with a cell death defect die. The researchers demonstrated that when they cause worm mitochondria to fragment without instructing cells to die, the cells stil...

Defenseless plants arm themselves with metals

...'s already resisting pathogens, why do you need an extra mechanism? There has to be more to it." It turns out the plants Salt studies - a group of small, weedy alpine flowers called Thlaspi - lack the standard pathogen defense mechanism found in nearly every other plant species. Thlaspi plants live in soi...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...ll known as Billy Idol, easily recognizable by the extra holes in his large ears. "He's got a lot of ear piercings, hence his name," she explains. Unlike the other males, whose trunks are frozen in midair, Billy Idol has placed his flat on the ground, the tip pointing inward toward his front feet. Billy an...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...man-caused nutrients in these special areas causes extra blooms of phytoplankton." Yaqui Valley agriculture To assess the impact of agricultural runoff on the gulf, the Stanford scientists turned their attention to one of Mexico's most productive coastal farming regions-the Yaqui River Valley, which drai...

Thai spice helps cut blood sugar swings

...u; slower is better." Besides the implication for extra sugar being stored (as fat) rather being used effectively, Dr. Agatston notes that with large sugar infusions, the body often produces too much insulin, which then lowers the blood sugar level. When that happens, he writes, "new cravings are created,...

Late peak may have prevented severe flu season from becoming worse

This extra time could have been responsible for preventing many more people from becoming ill than would have been expected under the circumstances if the flu peaked at the same time it did the year before. ### To see a graph showing hospital CAP admissions f...

Deep thinking: Scientists sequence a cold-loving marine microbe

Caloric restriction won't dramatically extend life span in humans: UCLA research

...nd life span. Phelan's conclusion is that the few extra years of life are not worth the suffering necessary to achieve them. "Do you want to spend decades severely limiting what you eat to live a few more years? You will be unhappy and then your life will end shortly after mine ends," Phelan jokes. Sci...

Professor Uwe Proske, from Monash's Department of Physiology, found when muscles were weakened from overuse or fatigue, limb control was affected, particularly if the person cou...

Slipping past the blood brain barrier: Research shows potential treatment for brain cancer

...lts. Researchers found that the P-gp system, an extra guardian located at the blood brain barrier that usually keeps anticancer drugs out of the brain, intercepted some of the JV-1-36 that was injected into mice but let much of it pass into the brain to treat cancer. "The blood brain barrier is set up ...

Mechanism regulating tooth shape formulation found

These results indicate that there is a delicate balance of induction and inhibition in determining tooth cusps and that ectodin is a key gene in this developmental control. The team confirmed the import...

The system takes advantage of the scarcity of the CG sequence, finding so-called CpG "islands" known to be more com...
