Researchers have discovered a faster, cheaper method for the diagnosis of tuberculosis (TB). A major barrier in TB prevention, especially in developing countries, is that diagnosis is slow and costly. Dr Olivier Braissant ...

Fighting antibiotic resistance with 'molecular drill bits'

In response to drug-resistant "superbugs" that send millions of people to hospitals around the world, scientists are building tiny, "molecular drill bits" that kill bacteria by bursting through their protective cell walls. ...

Leading bugs to the death chamber: A kinder face of cholesterol

Cells of our immune system kill pathogens by enclosing them in a compartment called the phagosome. The phagosome undergoes programmed maturation, where the pathogen is degraded. Intimately linked to this degradation is active ...

City living helped humans evolve immunity to TB

New research has found that a genetic variant which reduces the chance of contracting diseases such as tuberculosis and leprosy is more prevalent in populations with long histories of urban living.

In India: A search for more effective tuberculosis drugs

Rajesh Gokhale has created a compound in his lab in India that stops tuberculosis in its tracks. In a test tube, the molecule hits four of the bacterium's crucial metabolic pathways at the same time, weakening and ultimately ...
