Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate.
The events - one, a massive, long-lived drought believed to have dried large portions of Africa and Asia, and the other, a rapid cooling that accelerated the growth of tropical glaciers - left signals in ice core
COLUMBUS, Ohio -- Ohio State University cancer researchers have used computational and genomic methods to identify possible anti-cancer agents that may block a particular kind of tumor behavior. The agents target multiple genes associated with that behavior at one time.
The Department of Energy's Pacific Northwest National Laboratory announces the establishment of the Pacific Northwest Distinguished Postdoctoral Fellowship Program.
The laboratory is accepting applications for the new fellowships and will review candidates immediately for fall 2009 appointments.
Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years.
The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles
RICHLAND, Wash. -- DNA might be the blueprint for living things, but proteins are the builders. Researchers trying to understand how and which proteins work together have developed a new crosslinking tool that is small and unobtrusive enough to use in live cells. Using the new tool, the scientists have discovered new details about a well-studied complex of proteins known as RNA polymerase.
A new study suggests that delivering small RNAs, known as microRNAs, to cancer cells could help to stop the disease in its tracks. microRNAs control gene expression and are commonly lost in cancerous tumors.
Researchers at Nationwide Children's Hospital and Johns Hopkins University have discovered that delivering a small molecule that is highly expressed in normal tissues but lost in diseased cells can result in tumor suppression.
Scientists at Johns Hopkins have discovered a potential strategy for cancer therapy by focusing on what's missing in tumors.

Noticing the conspicuous absence of single-stranded genetic snippets called microRNAs in cancer cells, a team of researchers from Johns Hopkins and Nationwide Children’s Hospital delivered these tiny regulators of genes to mice with liver cancer and found that tumor cells
New natural treatments may help improve the quality of life for more than 21 million osteoarthritis (OA) sufferers, according to new research presented at the 2009 Institute of Food Technologists (IFT) Annual Meeting and Food Expo®.
San Diego, CA, June 9, 2009 -- While back pain, blurred vision and mouse-related injuries are now well-documented hazards of long-term computer use, the number of acute injuries connected to computers is rising rapidly.
Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement technique.
They discovered that a rare type of giant star, often overlooked by astronomers, could make an excellent signpost for distances up to 300 million light years -- and beyond.
Scientists here have determined that combining bed bugs' own chemical signals with a common insect control agent makes that treatment more effective at killing the bugs.
The researchers found that stirring up the bed bugs by spraying their environment with synthetic versions of their alarm pheromones makes them more likely to walk through agents called desiccant dusts, which kill the bugs by mak
New York, NY, June 4, 2009 -- In 2007, before the current economic downturn, an American family filed for bankruptcy in the aftermath of illness every 90 seconds; three-quarters of them were insured. Over 60% of all bankruptcies in the United States in 2007 were driven by medical incidents.
Spring marks baseball season for more than 19 million children and adolescents who play each year as part of a team or in backyards throughout the United States. The good news for these players is that the number of injuries from the sport is on the decline.
