Twitter ScienceDaily (Oct. 27, 2011) — Governments around the world must be prepared for mass migrations caused by rising global temperatures or face the possibility of calamitous results, say University of Florida scientists on a research team reporting in the Oct. 28 edition of Science.If global temperatures increase by only a few of degrees by 2100, as predicted by the U.N. Intergovernmental Panel on Climate Change, people around the world will be forced to migrate. But transplanting populations from...

ScienceDaily (Oct. 27, 2011) — Scientists outline new methods for better understanding links between specific proteins and the risks associated with Alzheimer's disease in an article co-authored by University of Alabama researchers and publishing in Science Express.In experiments using a series of model organisms, including yeast, microscopic roundworms and rats, the researchers show how basic mechanisms inside cells are disrupted when a specific human protein, known as the amyloid beta peptide,...

ScienceDaily (Oct. 28, 2011) — NASA's newest Earth-observing satellite soared into space early Oct. 28, 2011 aboard a Delta II rocket after liftoff at 5:48 a.m. EDT from Space Launch Complex 2 at Vandenberg Air Force Base in California.NASA's National Polar-orbiting Operational Environmental Satellite System Preparatory Project, or NPP, successfully separated from the Delta II 58 minutes after launch, and the first signal was acquired by the Tracking and Data Relay Satellite System. NPP's solar...

ScienceDaily (Oct. 27, 2011) — A new fourth-generation oncolytic virus designed to both kill cancer cells and inhibit blood-vessel growth has shown greater effectiveness than earlier versions when tested in animal models of human brain cancer.Researchers at the Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC -- James) are developing the oncolytic virus as a treatment for glioblastoma, the most common and deadly...

ScienceDaily (Oct. 27, 2011) — When a bacterial cell divides into two daughter cells and those two cells divide into four more daughters, then 8, then 16 and so on, the result, biologists have long assumed, is an eternally youthful population of bacteria. Bacteria, in other words, don't age -- at least not in the same way all other organisms do.But a study conducted by evolutionary biologists at the University of California, San Diego questions that longstanding paradigm. In a paper published in...

ScienceDaily (Oct. 28, 2011) — NASA scientists will be tracking asteroid 2005 YU55 with antennas of the agency's Deep Space Network at Goldstone, Calif., as the space rock safely flies past Earth slightly closer than the moon's orbit on Nov. 8. Scientists are treating the flyby of the 1,300-foot-wide (400-meter) asteroid as a science target of opportunity -- allowing instruments on "spacecraft Earth" to scan it during the close pass.Tracking of the aircraft carrier-sized asteroid will begin at...

ScienceDaily (Oct. 28, 2011) — Mammography saves lives by detecting very small tumors. However, it fails to find 10-25% of tumors and is unable to distinguish between benign and malignant disease. New research published in BioMed Central's open access journal Breast Cancer Research provides a new and potentially more sensitive method using tumor-targeted magnetic nanoprobes and superconducting quantum interference device (SQUID) sensors.A team of researchers from University of New Mexico School...
