Scientists at Gladstone Institute of Virology and Immunology have solved a long-standing mystery about HIV infection–namely how HIV promotes the death of CD4 T cells. It is the loss of this critical subset of immune cells that leads to the development of AIDS. Most immune cells that die during H... Read More

In the highlands of East Africa, malaria transmission has skyrocketed over recent decades. New research suggests rising temperatures are at least partly to blame.
A mathematical model of malaria transmission developed by Howard Hughes Medical Institute (HHMI) scientists showed that warming co... Read More
China had an estimated 1.3 million new cases of tuberculosis (TB) in 2008, of which 112,000 were multi-drug resistant (MDR-TB). Over the period 2001, TB was the second largest cause of death among China's 39 notifiable communicable diseases. In a Policy Forum, published in this week's PLoS Medic... Read More
Researchers funded by the BBSRC Crop Science Initiative have made a discovery that could instigate a paradigm shift in breeding resistance to late blight (Phytophthora infestans) - a devastating disease of potatoes and tomatoes costing the industry £5-6Bn a year worldwide.
By studying the in... Read More
Traditional virus diagnostic tools such as ELISA and polymerase chain reaction (PCR) remain strong diagnostic options, but they require significant infrastructure and sample preparation time.
