A team led by Professor Malcolm McConville from the Bio21 Institute, University of Melbourne developed a new analytical method which can be used for many infectious parasites and bacteria. The technique has revealed which metabolic pathways are essential for the parasite's survival, down to the particular atoms it uses as a food source.

This is a radiograph of adult Arikara specimen. Researchers at Johns Hopkins found that use over time and not just genetics informs the structure of jaw bones in human populations. The researchers say these findings may be used to predict the diet of an ancient population, even if little evidence exists in the fossil record. It can also make it easier for scientists to pinpoint the genetic relationship between fossils.

A Purdue University scientist is urging federal officials to decide whether genetically engineered salmon would be allowed for U.S. consumption and arguing that not doing so may set back scientific efforts to increase food production.
