Dartmouth College researchers have identified a new regulator for plant hormone signaling -- the KISS ME DEADLY family of proteins (KMDs) – that may help to improve production of fruits, vegetables and grains.
Developing new vaccines to protect against diseases that plague humans is fraught with numerous challenges—one being that microbes tend to vary how they look on the surface to avoid being identified and destroyed by the immune system.
Scientists at the Salk Institute for Biological Studies have identified a protein that drives the formation of pituitary tumors in Cushing's disease, a development that may give clinicians a therapeutic target to treat this potentially life-threatening disorder.
When it comes to deciding which light bulb to buy, a label touting the product's environmental benefit may actually discourage politically conservative shoppers.
Researchers have discovered that rising temperature induces key changes in the dengue virus when it enters its human host, and the findings represent a new approach for designing vaccines against the aggressive mosquito-borne pathogen.
Researchers at Columbia Engineering and Boston University have developed the first method to map evaporation globally using weather stations, which will help scientists evaluate water resource management, assess recent trends of evaporation throughout the globe, and validate surface hydrologic models in various conditions.
A structural biologist at the Florida State University College of Medicine has made discoveries that could lead scientists a step closer to understanding how life first emerged on Earth billions of years ago.
Mutations in a protein called SPOP (speckle-type POZ protein) disarm it, allowing another protein called steroid receptor coactivator-3 (SRC-3) to encourage the proliferation and spread of prostate cancer cells.
Think new discoveries are the bee's knees? This one is even better...
The Proceedings of the National Academy of Sciences of the United States of America (PNAS) is a peer-reviewed scientific journal established in 1914 as the official journal of the US National Academy of Sciences. The first managing editor of the journal was mathematician Edwin Bidwell Wilson. As of May 2012, the editor-in-chief is Inder M. Verma. PNAS is published weekly in print, and daily online in PNAS Early Edition. The first issue of PNAS was published in 1915, and the journal...
