No flu vaccine link to Guillain-Barré syndrome found
A massive study of millions of people in China finds no association between receiving the 2009 H1N1 immunization and developing the rare nervous system disorder.

Bioengineering better blood vessels
Durable conduits made with a tough protein produced by living cells might improve options for some patients who need heart bypass surgery or kidney dialysis, a new study finds.
- Psychology
Sometimes, happiness is for bozos
Despite its benefits, happiness and its pursuit has risks, as writer Bruce Bower describes in a humorous report from the recent meeting of the Society for Personality and Social Psychology.
- Humans
Early cow’s milk consumption may cut breast-cancer risk
Research studies paint a muddy picture of milk’s malignant threat. Some have linked consumption of cow’s milk with a heightened breast-cancer risk. Others have suggested milk drinking might be protective. A new animal study suggests those data may not be quite as contradictory as they at first seemed.

In tough economy, PhD appears to help
U.S. residents holding PhD’s in science, health and engineering were considerably more likely to be employed during late 2008 (the most recent period for which data are available) than were Americans generally, according to a just-released National Science Foundation report.
