Scientists take steps to make weak TB drugs strong again

Biophysicists have discovered why the bacteria that cause tuberculosis (TB) are naturally somewhat resistant to antibiotics known as fluoroquinolones. Their findings, based on mapping the detailed three-dimensional structure ...

Ultrashort-pulse lasers kill bacterial superbugs, spores

Life-threatening bacteria are becoming ever more resistant to antibiotics, making the search for alternatives to antibiotics an increasingly urgent challenge. For certain applications, one alternative may be a special type ...

Calcium bursts kill drug-resistant tumor cells

Multidrug resistance (MDR)—a process in which tumors become resistant to multiple medicines—is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that ...

Nanotech drug smugglers

Tiny capsules of carbon are invisible to the chemical gatekeeper that flushes potentially harmful substances out of our bodies' cells, according to research published in the International Journal of Computational Biology ...
