The contrast is staggering. On one side of a narrow track is cool, moist rainforest, stretching northwest for hundreds of kilometers through the almost intact Xingu indigenous reserve. 

There are an estimated 20,000 to 30,000 proteins at work in cells, where they carry out numerable functions, says computational molecular biologist Roman Sloutsky at the University of Massachusetts Amherst. “One of the central questions in all of biochemistry and molecular biology,” he adds, is how their precisely-tuned functions are determined.

There is no effective vaccine available to prevent Lyme disease in humans, but researchers are one step closer to developing new vaccines and a hybrid approach that can deliver a one-two punch to the microbe that causes the disease and its tick carrier.

A new study, published in Science, which focuses on mapping biodiversity change in marine and land ecosystems shows that loss of biodiversity is most prevalent in the tropic, with changes in marine ecosystems outpacing those on land.

Predicting and controlling disease outbreaks would be easier and more reliable with the wider application of mathematical modelling, according to a new study.
