Science Daily- Fast pace of glacier melt in the 1940s: lower aerosol pollutionIn the 1940s Swiss glaciers were melting at an even-faster pace than at present, according to new research. This is despite the fact that the temperatures in the 20th century were lower than in this century. Researchers see the main reason for this as the lower level of aerosol pollution in the atmosphere.
- New research could advance research field critical to personalized medicineIt's the ultimate goal in the treatment of cancer: tailoring a person's therapy based on his or her genetic makeup. While a lofty goal, scientists are steadily moving forward, rapidly exploiting new technologies. Researchers report a significant advance in this field of research using a new chip that looks for hundreds of mutations in dozen of gene […]
- New molecule identified in DNA damage responseIn the harsh judgment of natural selection, the ultimate measure of success is reproduction. So it's no surprise that life spends lavish resources on this feat, whether in the courtship behavior of birds and bees or replicating the cells that keep them alive. Now research has identified a new piece in an elaborate system to help guarantee fidelity in th […]
- The cancer 'TRAP': protein may prevent cancer cell deathNew research suggests that TNF-receptor associated protein-1 (TRAP-1) may prevent cancer cell death.
- Window opens into Moon's past volcanismLava tubes, underground cave-like channels through which lava once flowed, are commonly found on Earth. Scientists have debated whether these tubes could form on the Moon as well, but no studies have yet conclusively identified features that indicate the presence of lunar lava tubes.
- Student sleuths using DNA reveal zoo of 95 species in NYC homes -- and new evidence of food fraudTwo New York City high school students exploring their homes using the latest high-tech DNA analysis techniques discover a veritable zoo of 95 animal species surrounding them, in everything from fridges to furniture, from sidewalks to shipping boxes, and from feather dusters to floor corners.
- Quelling Casimir: Scientists to control quantum mechanical forceScientists are developing a way to control the Casimir force, a quantum mechanical force that attracts objects when they are only hundred nanometers apart.
- Mutation leads to new and severe form of bacterial diseaseFighting an illness is not just about fighting the bacteria or viruses that cause it, it also has to do with your genes. Scientists have now identified a gene mutation that makes children susceptible to a severe form of mycobacterial disease, any disease caused by species of Mycobacterium such as tuberculosis and leprosy. The mutation represents a new layer […]
- Protein link may be key to new treatment for aggressive brain tumorBiomedical researchers have found a protein that could hold the key to treating one of the most common and aggressive brain tumors in adults. Glioblastoma multiforme, the type of malignant brain tumor that killed the late US Sen. Edward Kennedy, is difficult to treat because it spreads cancerous cells to other parts of the brain very quickly. About 10,000 ca […]
- New suppressor of common liver cancerTumor suppressor genes make proteins that help control cell growth. Mutations in these genes that generate nonfunctional proteins can contribute to tumor development and progression. One of the most well-known tumor suppressor genes is BRACA1, mutations in which are linked to breast cancer. Researchers have now identified SCARA5 as a candidate tumor suppress […]
