Virus infections-it’s a zoo in there!

She highlights the interaction between HIV and two other viruses, human herpesvirus-6 and GB-virus-C. Infection with the first hastens HIV disease and infection with the second…
Did the dinosaurs die of malaria?
The other week I heard about a recently published book (‘What bugged the dinosaurs? Insects, Disease and Death in the Cretaceous‘, by George and Roberta Poinar) which argues that disease-transmitting insects played an important role in the extinction of the dinosaurs.

Omega-3 fatty acids – what have we learned?
Animal studies have suggested that a specific fatty acid, docosahexaenoic acid (DHA), plays a role in the development of cognitive abilities. So will taking extra DHA as a child make you cleverer?
The new HIV or just an outbreak of boils?
An aggressive and drug resistant version of the hospital superbug MRSA is spreading through the gay community in San Francisco.

Cryptosporidium and Giardia in drinking water: not just a problem for industrialised countries
Dr. Lucy Robertson, a speaker at the 8th Central American and Caribbean Congress on Parasitology and Tropical Medicine 2007, points out that as countries strive to improve their standards of public health, we should find it intolerable to accept the transmission of these infections via drinking water anywhere.

It is still an open question whether biofuel can meet a significant proportion of the world’s energy needs, say John Fike and co-authors in a paper in CAB Reviews
