Global schemes to fight climate change may miss their mark by ignoring the "fundamental connections" in how food is produced, supplied and consumed, say scientists in a new paper published in the journal Nature Food.

Brazilian researchers found the level of uric acid in saliva to be a good indicator of body fat percentage in a study designed to identify reliable biomarkers that can be used to develop quick noninvasive tests for early detection of chronic diseases.

Researchers Butantan Institute succeeded in reducing the toxicity and potentiating the analgesic effect of crotoxin by encapsulating it in nanostructured silica. The results of tests in an animal model of neuropathic pain are promising.

Astrocytes are neural cells with many important functions in the nervous system. The inflammation of these cells occurs in brain infections and neurodegenerative disorders, a process called astrogliosis. Aware of this fundamental process for the prevention of diseases and improvement of current treatments, a team led by researchers at the D'Or Institute for Research and Education (IDOR) and other five Brazilian Federal Universities published one of the first studies to categorically observe this inflammatory reaction in human astrocytes created in the laboratory.

Thanks to the use of high-resolution microcomputed tomography, a cross-border research collaboration was able to study the only three known specimens of Tembeassu marauna, held at the University of São Paulo's Zoology Museum.

Only about 1% of marine plastic debris is recovered at the ocean's surface, meaning the other 99% likely either sinks or is consumed by marine organisms

Compounds based on palladium, a metal belonging to the same group as platinum, have been developed by researchers from Brazil, the UK and Italy. In vitro tests show action against tumor cells that are resistant to treatment currently used.

Few studies have identified the effects of zika virus infection on astrocytes, as well as their association with developmental alterations, including brain malformations and microcephaly. Published in Scientific Reports, a new article sought to unravel the virus reactions on laboratory-created astrocytes, comparing them to the same cells present in the brain tissue of animals and fetuses infected with Zika.

The most common groups of soil protists behave exactly like Pac-Man: moving through the soil matrix, gobbling up bacteria according to a new article in Science Advances.
