The pine tree stand initiated around 12,900 years ago during the relatively warm “Allerød” period, and continued growing into the cold snap of the ... Read More »

New clues found to understanding relapse in breast cancer

A large genomic analysis has linked certain DNA mutations to a high risk of relapse in estrogen receptor positive breast cancer, while other mutations were associated with better outcomes, according to researchers from Washington University School of Medicine in St. Louis, the Baylor College of Medicine and the University of ...

Mud from the deep sea reveals clues about ancient monsoon

Analyzing traces of leaf waxes from land plants that over millennia accumulated in deep sea sediments, a team of researchers led by the University of Arizona reconstructed the history of monsoon activity in northern Mexico. Their results, published online on Sept. 3 in the journal Nature Geoscience, help settle a ... Read More »

Genomic study of 412 anthrax strains provides new virulence clues

By analyzing genomic sequences from more than 400 strains of the bacterium that causes anthrax, researchers have provided the first evidence that the severity — technically known as virulence — of specific strains may be related to the number of copies of certain plasmids they carry. Plasmids are genetic structures ... Read More »
