...A new study has found that the gene BRAF is frequently mutated in melanomas that develop on areas of the skin that are intermittently exposed to the sun. In contrast, BRAF mutations in melanomas on chronically sun-damaged skin and skin unexposed to the sun are rare. The discovery "strongly suggests distinct genetic pathways leading to melanoma," say study authors Janet L. Maldonado and Boris...JCI table of contents, December 15 2003
... ...Normal cell growth requires well-coordinated balance between synthesis and breakdown. Autophagy is a regulated lysosomal pathway whereby long-lived cellular proteins and cytoplasmic organelles are degraded. The beclin 1 autophagy gene is monoallelically deleted in 40-75% of cases of human sporadic breast, ovarian, and prostate cancer. However, little is known about the role of au...It's our holiday gift to you this year: a stocking-full of great science stories -- some of which are timely, some of which are evergreen -- but all are great leads to fill these otherwise barren winter months.

BOULDER, Colo. - Highlights from the Geological Society of America's November issue of GEOLOGY include a new "curveball" of evidence to the Snowball Earth hypothesis, findings about magma coming from the Earth's mantle in the Arctic Gakkel Ridge eruption, details about the discovery of Canada's oldest shelly fossils, decreased solar forcing as a trigger for a cooling event during the early Holoce...2001 ICAAC postponed until December
Because of the current situation in the United States, the American Society for Microbiology finds that it now must postpone the 41st Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) originally scheduled in Chicago, September 22-25, 2001. The ASM and the ICAAC Scientific Program Committee had hoped to proceed with this major infectious disease meeting. However, as events c...Press invitation: The science of stem cells - December symposium at Imperial College
.As the British parliament prepares to debate a change in the law to allow stem cells from human embryos to be used in research, Imperial College researchers will gather at a Symposium in December to discuss the science behind stem cells, and examine their potential to provide new treatments for a host of diseases.. .Journalists are invited to attend the Symposium Stem Cells and Development at t...December Geology and GSA Today highlights
. Following are highlights from the December issue of GEOLOGY and a summary of the science article from the December issue of GSA TODAY, published by the Geological Society of America. Stories written regarding these articles are embargoed until December 1. We ask that you discuss articles of interest with the authors before publishing stories on their work, and that reference be made to GEO.... Teenagers tend to have a harder time functioning in the morning than their parents do. Long flights can cause jet lag. Both phenomena are related to "biological clocks," molecular mechanisms that regulate how humans and other organisms sleep, wake and function throughout a 24-hour day. And if "the early bird gets the worm," it's because birds also have a built-in clock that helps them to rise....Washington, DC - A team of scientists has discovered that some widely-prescribed cholesterol-lowering drugs also have impressive bone-building capabilities that may make them effective drugs for treating osteoporosis. The team's findings appear in the 3 December issue of .. .These drugs, known as statins, represent an entirely new approach to treating osteoporosis, one which emphasizes buildin...NTP-CERHR announces the Second Phthalates Expert Panel Meeting to be held December 15-17, 1999
