Evolutionary gene mutation unique to humans may be to blame for risk of advanced cancers

Compared to chimpanzees, our closest evolutionary cousins, humans are particularly prone to developing advanced carcinomas -- the type of tumors that include prostate, breast, lung and colorectal cancers -- even in the absence of known risk factors, such as genetic predisposition or tobacco use.

Link between evolution of microevolution and macroevolution could provide new foundation for biology

A link between evolution over short time frames (microevolution) and long time frames (macroevolution) that could open new approaches to understanding some of biology's deepest questions is proposed by Dr Owen Gilbert of the Department of Integrative Biology at the University of Texas at Austin (USA) in a new paper, published in the open-access, peer-reviewed journal Rethinking Ecology.

Researchers identify new mechanism through which plants can regulate gene expression

Just like other organisms, plants must respond dynamically to a variety of cues over their lifetime. Going through different developmental stages, or altering their form in response to a drought or drastic temperature change requires altering which of their genes are expressed into proteins and when those processes occur.

Seasonal changes transmit bacterial plant pathogen to perennial trees, vine crops

The bacterial plant pathogen Xylella fastidiosa is a worldwide threat to perennial tree and vine crops and has been linked to Pierce's disease of grapevine in California, olive quick decline in Italy, and citrus variegated chlorosis in South America.

Study reveals rare spawning behavior of shallow-water fish

A new study provides the first detailed documentation of a shallow-water fish diving 450 feet deep to spawn. Uncovering this very rare spawning behavior in bonefish (Albula vulpes) is unprecedented.
