First Global Estimates of Long-Term Fine Particulate Matter Concentrations Show High Impact on Air Quality in Many Regions

A study published 16 March 2010 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP) finds that many developing countries have high long-term levels of aerosol air pollution. The study is the first to use satellite data to estimate long-term fine particulate matter (PM2.5) concentrations across the entire globe.

Keeping Up with the Neighbors Speeds Vaccine Use

Researchers at the Johns Hopkins Bloomberg School of Public Health conducted an analysis of worldwide use of Haemophilus influenza Type b vaccine (Hib) to determine what factors influenced a nation’s adoption of the vaccine.

Proton-Pump Inhibitor Plus Clopidogrel Is Less Likely to Cause Bleeding Ulcers

Heart patients who took a stomach acid-suppressing proton-pump inhibitor along with clopidogrel – a drug that prevents blood clots – were only half as likely to be hospitalized for upper digestive tract bleeding than those who used clopidogrel alone.

Generic Drug for Type 2 Diabetes Passes Next Clinical Hurdle

Salsalate, an anti-inflammatory agent, shows encouraging results in preliminary trial led by Joslin Diabetes Center.

Urged on by Urchins: How Sea Lilies Got Their Get-Up-and-Go

Nature abounds with examples of evolutionary arms races. Certain marine snails, for example, evolved thick shells and spines to avoid be eaten, but crabs and fish foiled the snails by developing shell-crushing claws and jaws.

U-M Researchers Solve a Molecular Mystery in Muscle

The muscle-building abilities of hormones known as insulin-like growth factors (IGFs) are legendary. Just do an online search and you'll find not only scientific papers discussing the effects of IGFs on the cells that give rise to muscle tissue, but also scores of ads touting the purported benefits of IGF supplements for bodybuilding.
