New research from the University of Cincinnati (UC) points to the naturally produced protein apolipoprotein A-IV (apoA-IV) as a potential target for a new diabetes therapeutic.
To become better healers, tissue engineering need a timely and reliable way to obtain enough raw materials: cells that either already are or can become the tissue they need to build.
A new study finds that nine percent of the Western Hemisphere's mammals will fall victim to the changing climate.
The study, published yesterday in the journal Proceedings of the National Academy of Sciences (PNAS), looked at how genes on sex-linked chromosomes are passed down generations and linked to fertility, using the specific example of the W chromosome in female chickens.
Scientists at Cold Spring Harbor Laboratory (CSHL) and Memorial Sloan-Kettering Cancer Center have amassed strong experimental evidence implying that commonly occurring large chromosomal deletions that are seen in many cancer types contain areas harboring multiple functionally linked genes whose loss, they posit, confers a survival advantage on growing tumors.
A team led by Johns Hopkins engineers has discovered some previously unknown properties of a common memory material, paving the way for development of new forms of memory drives, movie discs and computer systems that retain data more quickly, last longer and allow far more capacity than current data storage media.
Current nanomedicine research has focused on the delivery of established and novel therapeutics.
As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away.
Macrophages playing an important role in the immune system eat and fight against pathogens and foreign substances in the very beginning of infection.
Using computational methods, Stanford University School of Medicine investigators have strongly implicated a novel gene in the triggering of type-2 diabetes.
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...
