Special microbes make anti-obesity molecule in the gut
You’ve probably heard of all sorts of diets, paleo, low-fat, low-carb, atkins, but now microbes may just be the next diet craze. Researchers have programmed bacteria to generate a molecule that, through normal metabolism, becomes a hunger-suppressing lipid (fat). Mice that drank water laced with the programmed bacteria ate less, had lower body fat and staved off diabetes — even when fed a high-fat diet — offering a potential weight-loss strategy for humans.
New antibiotic may help slow drug resistance
Antibiotic resistance, a hot topic lately here at the labs, as evidence by this recent post. So it is fortuitous that I stumbled upon this little bit of research that suggests scientists (using a “revolutionary” approach) have devised an antibiotic that may offset the mounting problem of drug resistance for decades… hopefully.
Outsmarting superbugs’ countermoves to antibiotics
With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades — such as pneumonia or urinary tract infections — are proving trickier to treat with standard antibiotics. New drugs are desperately needed, but so are ways to maximize the effective lifespan of these drugs.
Penicillin 2.0 – Reviving an Old Winner

Penicillin, it was one of the great feats of science and has saved countless lives. Antibiotics have been fighting the war on infections since before most of us were even alive. But since the 1960’s they have been fighting a losing battle, with the rise of new ‘super’ bugs penicillin and friends just doesn’t seem to cut it.
