Researchers identify genes associated with lung transplant rejection

...SFVAMC. "If we know rejection is occurring, we can adjust the patient's medication to try and prevent it. But the problem with lung transplants is that it's hard to detect chronic rejection." Currently, he says, OB is best detected through a breathing test--but by the time the disease has a perceptible impa...

Scientists focus on 'dwarf eye'

...edness," he said. "However, a mouse's eyes do not adjust their focus through growth like human eyes do, so MFRP has a completely different function in mice and was not assumed to alter eye refraction in humans." The research team successfully mapped the MFRP gene mutation in humans and discovered that t...

Bumblebees copy one another when contending with unfamiliar flowers

... of other bees. The new findings suggest that bees adjust their behavior when dealing with flowers of unfamiliar plant species. The observations are reported in the June 21 issue of Current Biology in a new paper by Elli Leadbeater and Lars Chittka of Queen Mary, University of London. Bumblebees are highl...

Two studies document rise of superbugs in the environment

... communities so they can monitor for increases and adjust treatment accordingly. Prevention of MRSA infections mainly involves common sense. "If you get a cut or an abrasion, try to keep it clean and dry" and don't share towels or washcloths with others, Dr. Kaplan said. Most importantly, he added, "Wash h...

Although the cells' channel-changing ability has been recognized for a few years, the key players controlling it hadn't been identified. Now, by studying mice, the ...

Crucially, Wilmers and Getz's study shows that a robust food chain - including this still embattled top predator - may be even more important as ecological conditions deteriorate. ### Citation: Wil...

This finding has important implications for climate change since the amount of carbon removed from the atmosphere d...
