Mechanism that underlies age-associated bone loss  

A major health problem in older people is age-associated osteoporosis -- the thinning of bone and the loss of bone density that increases the risk of fractures. Researchers have now detailed an underlying mechanism leading to that osteoporosis. When this mechanism malfunctions, progenitor cells stop creating bone-producing cells, and instead create fat cells. Knowledge of this mechanism can provide targets in the search for novel bone-loss.

Life-threatening infections occur when the bacteria spread underneath the surface of the skin or throat and invade the underlying soft tissue. Researchers have found two group A Streptococcus genes involved in invasive infections, which may be potential targets for therapeutics.

Rather, many scientists agree if there was life on the Red Planet, it probably will present itself as fossilized bacteria. To find it, astrobiologists likely will need to decode the chemical analysis of rock samples performed by a rover (like the one NASA plans to send to Mars in 2020)

Panda Gut Microbes Change with the Seasons  

A change in seasons can mean it's time to take the sweaters out of the back of your closet, plant your garden, or—if you're a panda—remake your gut microbiome. Scientists have found that pandas, rather than a summer and winter wardrobe, have different sets of gut bacteria for different seasons. The rotating roster of bugs helps pandas make the most of their drab diet of bamboo, bamboo and more bamboo. The panda menu does have seasonal variations. Pandas munch more on different bam...

Outdoor air pollution may increase the risk of chronic kidney disease and contribute to kidney failure, say researchers. Scientists culled national VA databases to evaluate the effects of air pollution and kidney disease on nearly 2.5 million people over a period of 8.5 years, beginning in 2004.

Party discipline for jumping genes  

Jumping genes, transposons, are part of the genome of most organisms, aggregated into families and can damage the genome by jumping. How hosts suppress the jumping is well investigated. Why they still can jump has hardly been understood so far. Researchers investigated for the first time in all transposons of the host organism, which properties and host environments facilitate jumping. They showed that family affiliation is more important than position.
