What leech gut bacteria can tell us about drug resistance

These microbes were exposed to surprisingly tiny amounts of antibiotics By Leah Rosenbaum BLOODSUCKER Medicinal leeches like this contain bacteria in their guts that can be transferred to humans. In some cases, it only takes a small exposure to antibiotics for those bacteria to become drug resistant. KARL RAGNAR GJERTS...

Paralyzed mice regain movement in their legs with new treatment

The drug reactivates nerve pathways in partially severed spinal cords. Most people with spinal cord injuries are paralyzed below the injury site, even if the cord is only partially severed. Researchers dont know why the nerve pathways that are still intact also stop working. A new study provides a promising answer and ...
