Researchers identify protein pathway involved in Parkinson disease development

... damage, this system can break down in the face of environmental challenges or genetic mutations. The Emory researchers found that the mitochondrial protein PINK1 normally protects cells from oxidative stress and promotes cell survival by regulating function of the protein TRAP1. When PINK1 is mutated, however...

First confirmed common genetic risk factors for breast cancer

...ties that can result from chance or exposure to an environmental toxin, such as excessive UV sunlight. However, BRCA-1, BRCA-2 and the other previously identified breast cancer susceptibility genes are mutated in a relatively small percentage of women. "Risk mutations within these genes are so rare that only a ...

The ecology of picoeukaryotes, said Moreau, has thus become an intense field of investigation over the last decade as these microalgae, although representing a minor component of th...

More recycling on the farm could reduce environmental problems

Growing environmental problems resulting from farming argue for a shift toward practices that use lower inputs of pesticides and energy and more recycling of energy and materials, according to an article published in the May 2007 issue of BioScience. The author, Craig J. ...

Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems

...ed when the scientists controlled for location and environmental conditions. “The ecology of islands is particularly important because, while the world’s more than 100,000 islands constitute only 7 percent of the global land surface, they contain many of the earth’s species with numerous species restricted to s...

Scientists: As rainfall changes, tropical plants may acclimate

... plants are highly specialized in their own little environmental niches ?and thus very sensitive to disturbances of those niches. That could be good for the plants because climate change is expected to radically alter rainfall patterns in the tropics. But it comes with a caveat: Nutrient uptake is only one of m...

Healthy coral reefs hit hard by warmer temperatures

...oral need to survive. When disease or stressful environmental conditions strike a coral colony, the polyps expel their algae. This algae loss makes the coral appear pale. "We're left with a big question. Can corals and other marine species successfully adapt or evolve, when faced with such change?" Rice said...

For example, when he conducted the experiment at 4 degrees Celsius, the baker’s yeast recognition element switched on. At 37 degrees Celsius, the pathogenic fungi element was activated. In other words, temperature alo...

DOE JGI sets 'gold standard' for metagenomic data analysis

...hods to see which performs best for the particular environmental samples being analyzed. "What we did was to take known sample genomes, shuffle them, create simulated metagenomes, and use those tools on them, and then we went back and compared the results to the isolate genomes. Essentially, we applied the gold ...

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event
