Measuring earthshine: How new terra data are improving weather and climate forecast models

A sensor aboard NASA’s Terra satellite is helping scientists map how much sunlight the Earth’s surface reflects back up into the atmosphere, and this new detailed information should help to greatly improve weather and forecast models. The Moderate Resolution Imaging Spectroradiometer (MODIS) now routinely provides daily global and local measurements of albedo, or the total amount of light reflected from Earth’s surface out to space. These precise data may allow scientists to better understand and pr

Diabetes treatment linked to increased blood pressure in animal study

A report in the July issue of the Journal of Clinical Investigation has found that a group of drugs currently under development for the treatment of Type II diabetes caused both increased heart rate and elevated blood pressure in animal studies. These new findings regarding glucagon-like peptide (GLP-1) receptor agonists suggest that the brain’s GLP-1 system has the ability to affect autonomic function, leading to changes in heart rate and blood pressure. A naturally occurring

Virus in babies may cause asthma later on

While most scientists believe that allergies cause asthma, researchers at Washington University School of Medicine in St. Louis are uncovering a second potential cause for this common respiratory illness. Their new model suggests that a viral infection in the first years of life may leave a lasting mark on the immune system, causing chronic respiratory problems later on. “While the allergic response may increase during an asthma attack, our research suggests that the anti-viral response also

Unique feeding behavior discovered for snakes

Field Museum scientists describe “loop and pull” in Nature Snakes are known to swallow their prey whole, which limits the size of what they can eat. But now scientists have discovered that a species of snake can tear apart its prey. This snake loops its body around a crab to hold one end while using its mouth to pull off legs or rip the crab’s body into pieces. This “loop and pull” method allows a snake to eat crabs that are relatively huge – far too large to swallow whol

Study finds common knee surgery no better than placebo

Patients with osteoarthritis of the knee who underwent placebo arthroscopic surgery were just as likely to report pain relief as those who received the real procedure, according to a Department of Veterans Affairs (VA) and Baylor College of Medicine study published in the July 11 New England Journal of Medicine. The researchers say their results challenge the usefulness of one of the most common surgical procedures performed for osteoarthritis of the knee. “The fact that the effecti

Long-term interruption of HIV treatment may be safe in certain patients

Interrupting anti-HIV treatment for an extended period and then re-initiating therapy might be safe in some patients, according to a study by Northwestern University infectious disease experts. Chad Achenbach, M.D., and co-investigators from The Feinberg School of Medicine presented data from their research today at the XIV International AIDS Conference. In an observational study, 25 HIV-infected patients with viral suppression for at least six months while receiving highly active a
