Ancient brew masters tapped antibiotic secrets:
A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer. The finding is the strongest evidence yet that the art of making antibiotics, which officially dates to the discovery of penicillin in 1928, was common practice nearly 2,000 years ago. The study finds that it's likely this prehistoric population was using empirical evidence to develop therapeutic agents.

New evidence that fat cells are not just dormant storage depots for calories:
Scientists are reporting new evidence that the fat tissue in those lower belly pooches -- far from being a dormant storage depot for surplus calories -- is an active organ that sends chemical signals to other parts of the body, perhaps increasing the risk of heart attacks, cancer, and other diseases. They are reporting discovery of 20 new hormones and other substances not previously known to be secreted into the blood by human fat cells and verification that fat secretes dozens of hormones and other chemical messengers.
