A novel road safety intervention in Guangzhou, China, has shown the potential for significantly increasing the use of seat belts among drivers and front seat passengers in motor vehicles.

1 of life's most common compounds causes allergic inflammation
The beetle's back and the crab's shell owe their toughness to a common compound called chitin that now appears to trigger airway inflammation and possibly asthma, UCSF scientists have found.

Study links faulty DNA repair to Huntington's disease onset
Huntington's disease, an inherited neurodegenerative disorder that affects roughly 30,000 Americans, is incurable and fatal.

First demonstration of muscle restoration in an animal model of Duchenne muscular dystrophy
Using a new type of drug that targets a specific genetic defect, researchers at the University of Pennsylvania School of Medicine, along with colleagues at PTC Therapeutics Inc. and the University of Massachusetts Medical School, have for the first time demonstrated restoration of muscle function in a mouse model of Duchenne's muscular dystrophy (DMD).

Motile Cilia go with the flow
Cilia, tiny hair-like structures that propel mucus out of airways, have to agree on the direction of the fluid flow to get things moving.

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place
