Taking on characteristics from another, younger stage in its life-cycle, a newly named fossil crab species was able to adapt to new conditions.

A genetic and computational analysis of birds suggests that the Andean and Atlantic tropical forests, which are now almost a thousand kilometers apart, were connected via the Cerrado in the distant past.

Less than one hour of brain training with neurofeedback leads to a strengthening of neural connections and communication among brain areas. This is the main finding of a new study conducted at D'Or Institute for Research and Education (IDOR), published today in Neuroimage. According to the authors, the study may pave the way for the optimization and development of therapeutic approaches against stroke and Parkinson's, for example.

Method developed by scientists in Brazil and Canada can prevent transmission of diseases to organ recipients. The number of transplants could be higher if organs could be decontaminated.

Researchers at the International Center for Tropical Agriculture (CIAT) have shown that Brachiaria grass species can reduce greenhouse gas emissions from cattle and increase productivity -- and breeding improved varieties can potentially augment the environmental and economic benefits. A breakthrough on Brachiaria's complex genome may make breeding much more efficient, and potentially increase the speed with which new grasses begin benefiting cattle farmers and the environment.

Giant Magellan Telescope (GMT), in Chile's Atacama Desert, will help to obtain answers on the formation and evolution of these exotic environments, as well as the possibility of life there.
