Scientists have discovered a previously unidentified nearby source of high-energy cosmic rays. The finding was made with a NASA-funded balloon-borne instrument high over Antarctica.
A new class of compounds called phosphaplatins can effectively kill ovarian, testicular, head and neck cancer cells with potentially less toxicity than conventional drugs, according to a new study in the journal Proceedings of the National Academy of Sciences.
Physicists can now make droplets dance, float and bounce above a surface, keeping small amounts of fluid free of contamination and ripe for testing.

A growing number of geneticists are using genome-wide association studies (GWAS) to systematically search for and identify single nucleotide polymorphisms (SNPs), which are single base changes in the human DNA sequence that can cause differences in genetic characteristics. GWAS may also detect genes that are associated with a particular health condition, or with variation in [...]

Biologists have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes. New research in Cell explains how RNA polymerases work together to use the non-coding region of DNA to prevent destructive, virus-derived genes from being activated. This research adds to a growing body of evidence suggesting that “junk DNA” [...]

When given a choice between viewing pictures of cocaine and a variety of other images, cocaine addicted individuals, as compared to healthy, non-addicted research subjects, show a clear preference for the drug-related images.

Scientists have completed the genome-wide sequence of an extinct animal. The scientists sequenced the genome of the woolly mammoth, an extinct species of elephant that was adapted to living in the cold environment of the northern hemisphere. They sequenced four billion DNA bases using next-generation DNA-sequencing instruments and a novel approach that reads ancient DNA [...]
A new study sheds new light on the way one of our cell enzymes, implicated in causing tissue damage after heart attacks and strokes, is normally kept under control.

Researchers say turtles nesting along the Mississippi River and other areas are altering their nesting dates in response to rising temperatures.

Working out on a stationary bicycle or walking on a treadmill just 25 to 30 minutes most days of the week is enough to modestly lower risk of hospitalization or death for patients with heart failure, say researchers.
