New way to fight antibiotic-resistant bacteria: Target human cells instead

January 10, 2014 12:07 pm | News | Comments

As more reports appear of a grim “post-antibiotic era” ushered in by the rise of drug-resistant bacteria, a new strategy for fighting infection is emerging that targets a patient’s cells rather than those of the invading pathogens. The approach involves looking at a class of proteins called phosphatases that is crucial for bacterial but involves the use of the host cell’s machinery.

A Synthetic Solution Saves Lives

January 9, 2014 2:24 pm | by Lindsay Hock | Articles | Comments

In the 2nd century BC, Indian surgeon Sushruta used autografted skin transplantation in nose reconstruction, also known as rhinoplasty. This was the first reasonable account of organ transplantation recorded. The first successful human corneal transplant was performed in 1905 in the Czech Republic, and the first steps to skin transplantation occurred during World War I. The first successful kidney transplant happened in 1962 in the U.S.
