As the climate changed over the past million years, areas of paramo around Andean peaks in Colombia grew and contracted, giving rise to species unique to this habitat. Today paramos continue to shrink, putting these species at risk.

In experiments with mice, Brazilian scientists demonstrated that a moderate training protocol reduced liver fat and made the organ more sensitive to insulin, even before loss of body weight occurred.

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.

Study shows that brain activity related to auditory perception parallels heart rate, offering new perspectives for the treatment of attention and communication disorders.

A study by the FAPESP-funded Research, Innovation and Dissemination Center shows that toxins produced by young female stingrays cause more pain, whereas toxins produced by adult stingrays cause tissue necrosis.

Better understanding agriculture and the food system's unique place in climate change -- as both drivers of climate change and victims of it -- is helping to increase support for climate action. Unfortunately, progress across the food system is lagging, according to a new analysis.

Animals first developed fever as a response to infections: the higher body temperatures primed their immune systems. At the time, 600 million years ago, virtually all animal species were cold-blooded. They had to spend long periods of time in warm areas of their habitat to achieve fever-range body temperatures. Michael Logan, a Tupper Fellow at the Smithsonian Tropical Research Institute in Panama (STRI), believes pathogens may be the reason why warm-blooded creatures first emerged.
