Polymer glasses are versatile plastics widely used in applications ranging from aircraft windshields to DVDs. Scientists have now developed a theory that predicts how these materials age. The theory also explains why motions at the molecular level can have macroscopic consequences.

Scientists have discovered a new virus that was responsible for the deaths of three transplant recipients who received organs from a single donor in Australia.

Researchers at the Columbia University Mailman School of Public Health Greene Infectious Disease Laboratory have been playing an important role investigating viral disease incidence as it relates to honey bee colony deaths, specifically the increased deaths in bee colonies with unique symptoms, called Colony Collapse Disorder (CCD).

A naturally occurring compound found in many fruits and vegetables as well as red wine, selectively kills leukemia cells in culture while showing no discernible toxicity against healthy cells, according to a study by researchers at the University of Pittsburgh School of Medicine.

Following a four-year study, North Carolina researchers report that a test accurately predicts nitrogen concentrations in humid soils. Researchers hope that this test will help to reduce under- and over-applying nitrogen fertilizer to corn crops, which can be harmful to the environment and costly to growers.
