Antibiotic-resistant bacteria found in one of the deepest, most isolated caves in the world could mean good news in the battle against superbugs. Researchers from McMaster and the University of Akron have discovered a remarkable prevalence of such bacteria in New Mexico's Lechuguilla Cave, a place isolated from human contact until very recently.
The discovery that bacteria have developed defenses against antibiotics could indicate the presence of previously unknown, naturally occurring antibiotics that doctors could use to treat infections.
If you are an aging baby boomer and you've noticed it's a bit harder to drive to unfamiliar locations or to pick a new brand of olive oil at the supermarket, you can blame it on the white matter in your brain.

The move by the agency is intended to slow the indiscriminate use of the drugs in agriculture, which has made them increasingly ineffective in humans.
Patients with metabolic syndrome and diabetes are more likely to develop detectable levels of coronary artery calcium and to have greater progression of calcification than other patients, researchers found.
