The ocean is becoming an increasingly crowded place.
The upper class has a higher propensity for unethical behavior, being more likely to believe – as did Gordon Gekko in the movie “Wall Street” – that “greed is good,” according to a new study from the University of California, Berkeley.
Antisense oligonucleotides – short segments of genetic material designed to target specific areas of a gene or chromosome – that activated an enzyme to "chew up" toxic RNA (ribonucleic acid) could point the way to a treatment for a degenerative muscle disease called myotonic dystrophy.
Cells that die naturally generate a lot of internal debris that can trigger the immune system to attack the body, leading to diseases such as lupus.

An endocrine hormone used in clinical trials as an anti-obesity and anti-diabetes drug causes significant and rapid bone loss in mice, raising concerns about its safe use, UT Southwestern Medical Center researchers have shown.
In a study published last week in the prestigious Proceedings of the National Academy of Sciences of the United States of America, a team led by Dr. Vincent Poitout of the University of Montreal Hospital Research Centre (CRCHUM)* has made an important step forward in understanding how insulin secretion is regulated in the body.
University of Utah biologists found new evidence why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs – even though some of those genes make us susceptible to infections and to autoimmune diseases.
Scientists have demonstrated for the first time that certain cells circulating in human blood – so-called monocytes – are extremely sensitive to reactive oxygen species (ROS).
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...
