Genetically diverse bacterial strains that cause urinary tract infections differ in their ability to trigger protective immune responses in mice, potentially explaining why these infections frequently..

The evidence used to support the EPA's 2009 Endangerment Finding on greenhouse gases is even stronger and more conclusive now. This finding comes three months after a senior Republican senator sa..

Researchers have invented a new way to fabricate nanoscale 3D objects of nearly any shape. They can also pattern the objects with a variety of useful materials, including metals, semiconducting quantu..

Several new connections have been discovered between the proteins of the Ebola virus and human host cells, a finding that provides insight on ways to prevent the deadly Ebola virus from reproducing an..

New insights into how dengue and Zika viruses cause disease reveal strategies the viruses use to successfully infect their host and a link to microcephaly.

A weighty new study shows that CRISPR therapies can cut fat without cutting DNA. Researchers describe how a modified version of CRISPR was used to ramp up the activity of certain genes and prevent sev..

A whole-genome sequencing study of nearly 2,000 families has implicated mutations in 'promoter regions' of the genome — regions that precede the start of a gene — in autism. The study is t..

Scientists have identified a new catalyst that uses only about a quarter as much platinum as current technology by maximizing the effectiveness of the available platinum.

Research in mouse cells identifies defective metabolic pathway in aging immune T cells. The pathway is critical for switching T cells from dormancy into illness-fighting mode. In experiments, research..

Scientists are revising the history of one of the world's most important crops. Drawing on genetic and archaeological evidence, researchers have found that a predecessor of today's corn plan..
