Climate change triggered dwarfism in soil-dwelling creatures of the past

Ancient soil-inhabiting creatures decreased in body size by nearly half in response to a period of boosted carbon dioxide levels and higher temperatures, scientists have discovered.

The researchers' findings are published in the October 5, 2009, early online edition of the journal Proceedings of the National Academy of Sciences (PNAS).

Arctic sea ice recovers slightly in 2009, remains on downward trend, says U. of Colorado report

Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center.

Hypertension and diabetes are concern in long-term care of liver transplant patients

A recent study by researchers from the University of Colorado looked at post-transplant care to determine whether primary care physicians (PCPs) or hepatologists are better suited to manage the overall health care of patients who received a liver transplant (LT). Researchers learned that hepatologists believe metabolic complications to be common in LT patients, but not well controlled.

Bundling 2 low-cost heart drugs prevents heart attack and stroke in large, diverse population

October 1, 2009 (Oakland, Calif.) -- A program that bundled two generic, low-cost drugs -- a cholesterol-lowering statin and a blood pressure-lowering drug -- and gave daily doses to 68,560 people with diabetes or heart disease for two years is estimated to have prevented 1,271 heart attacks and strokes in the first year following the study period, according to a Kaiser Permanente study publ

Storm killers: LSU's Earth Scan Lab tracks cold water upwellings in Gulf

BATON ROUGE -- Complex interactions between the ocean and overlying atmosphere cause hurricanes to form, and also have a tremendous amount of influence on the path, intensity and duration of a hurricane or tropical weather event.

CU-Boulder space scientists set for final spacecraft flyby of Mercury

NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument, will make its third and final flyby of Mercury on Sept. 29 -- a clever gravity-assist maneuver that will steer it into orbit around the rocky planet beginning in March 2011.

High-sugar diet increases men's blood pressure; gout drug protective

A high-fructose diet raises blood pressure in men, while a drug used to treat gout seems to protect against the blood pressure increase, according to research reported at the American Heart Association's 63rd High Blood Pressure Research Conference.

"This is the first evidence of a role of fructose in raising blood pressure and a role for lowering uric acid to protect against that blood pr

The vasculature emerges as a potential therapeutic target in treating ADPKD liver cysts

As part of an effort to develop effective medical therapies that block the progression of liver cyst growth in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), researchers at the University of Colorado Anschutz Medical Center have found that the liver cyst walls develop and maintain a vasculature as they grow out from the body of the liver and that factors released by epithel

Our emotions can lead us astray when assessing risks, says new CU-Boulder study

If you find yourself more concerned about highly publicized dangers that grab your immediate attention such as terrorist attacks, while forgetting about the more mundane threats such as global warming, you're not alone.
