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.

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.

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.

A nonlethal dose of insecticide clothianidin can reduce honeybees' life span by half; once combined with the fungicide pyraclostrobin, it alters the behavior of worker bees to the point of endangering the whole colony.

With the aim of enhancing the quality of Brazilian space research output, scientists investigated the accuracy of different satellite data collections.

Without significant global reductions in greenhouse gas emissions, Colombia will have 60% less land suitable for rice production by the 2050s. Due primarily to increased temperatures and decreased rainfall -- as opposed to sea-level rise, which is the driver of projected change to rice production in some Asian countries -- the research shows suitable conditions will need to be found at higher elevations when low-altitude fields are too hot or dry for irrigated rice.
