Traffic may drive some people to diabetes
Urban air pollution — especially the particles and gases emitted by heavy traffic — can increase a senior citizen’s risk of developing type-2 diabetes, according to a new German study. If confirmed, its authors say, pollution would represent a “novel and potentially modifiable risk factor” for the metabolic disorder.

‘Miracle’ tomato turns sour foods sweet
Pucker no more: That seems to be one objective of research underway at a host of Japanese universities. For the past several years, they’ve been developing bio-production systems to inexpensively churn out loads of miraculin — a natural taste-altering protein that makes sour foods seem oh so sweet. Their newest biotech reactor: grape tomatoes.

Chicken poses significant drug-resistant Salmonella threat
More than one-in-five retail samples of raw chicken collected in Pennsylvania hosted Salmonella, a new study found — twice the prevalence reported in a 2007 U.S. Food and Drug Administration survey. And where the bacteria were present, more than half were immune to the germicidal activity of at least one antibiotic. Nearly one-third were resistant to three or more.

Yet tom-toms — or at least the stretched animal hides on their heads — can sometimes spew toxic anthrax spores into the air. Indeed, the Centers for Disease Control and Prevention recently highlighted the case of a previously healthy 24-year-old woman who nearly died, last December, after attending a “drumming circle” in New Hampshire.
