As the HIV/AIDS epidemic approaches its fourth decade, each year brings promising news of pioneering research to alleviate the scourge. Now scientists report a rapid method to access new molecules that could inhibit the virus that causes AIDS.

A major new insight into how hepatitis B virus works could pave the way for new drug treatments for the infection which is the major cause of liver cancer worldwide, report scientists.

A small and preliminary clinical trial has found that injecting a common cold-like virus into the eyes of age-related macular degeneration (AMD) patients - one of the leading causes of blindness in the US - can halt and even reverse the progression of the disease.

Slap it in front of a unit of concentration, such as molar, and it means that something exists in an extraordinarily small amount—think one part per quintillion. That’s the realm of SHERLOCK, a new diagnostic system that can detect attomolar levels of viruses in a sample and also distinguish Zika from its close relative, dengue. This exquisitely sensitiv...
