Herbivore drool defeats fungal defence

A report in Biology Letters shows that the drool of herbivores might help defeat the toxic fungal defences of the plants they graze on.

Grazing or cutting some plants induces a noxious chemical to be produced which deters hungry plant-eaters from revisiting them. The chemicals, called alkaloi... Read More

Viral relics show cancer's 'footprint' on our evolution

Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.

Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses th... Read More

New analysis of 'swine flu' pandemic conflicts with accepted views on how diseases spread

The most detailed analysis to date of the spread of the H1N1 2009 pandemic influenza virus, known informally as ‘swine flu’, has found that short-range travel was likely the primary driver for the 2009 pandemic in the United States, in contrast with popularly accepted views on the way diseases s...
