In a study of mice, where animals breathed air as polluted as the air in New York City, researchers showed that urban pollution may be as dangerous or even more dangerous than breathing second-hand smoke.

Seasonal flu epidemics are seeded by viruses that originate in East and Southeast Asia and then migrate around the world, research shows. By focusing on new flu strains emerging in Asia, scientists may be able to improve their forecast of seasonal flu strains and develop better vaccines, researchers say.
Researchers have developed a new drug that protects animals' bone marrow and gastrointestinal cells from being destroyed by radiation therapy, without reducing radiation’s effectiveness against tumor cells. Although radiation is an important weapon against cancers, drugs that limit radiation’s devastating effects on healthy cells are needed to reduce the potentially severe side effects of the therapy. The new drug CBLB502, tested in mice and monkeys, works by activating a well-known molecular pathway that some cancer cells use to stave off cell death, the researchers say.
Science Bacteria living on antibiotics.
Researchers have found that some bacteria don't drop dead when they encounter antibiotics, they actually thrive.
