Surveys conducted in the Cerrado since the 1990s show falling biodiversity as the agricultural frontier advances in the vicinity of Emas National Park. Species with biotechnological potential are dwindling and even disappearing.

Researchers at São Paulo State University tested the action of nanoparticles loaded with antibiotics and other antimicrobial compounds on cells infected by the bacillus that causes tuberculosis. The results suggest the strategy can overcome multidrug bacterial resistance.

The map is derived from a study conducted by researchers at Brazil’s space research institute and collaborators, and combined airborne laser scanning, satellite imagery and forest inventories. The results will support planning, conservation and sustainable management decisions.

The study is the first-ever demonstration of the anatomical substrate for the cardiac arrhythmias that occur in human yellow fever. The YF virus affects the liver most of all; other organs besides the liver, however, are also affected, including the kidneys, brain, lungs, spleen, pancreas and heart.

In the global push for nature-based solutions to mitigate climate change, forest restoration in the tropics often takes the spotlight, but a new study shows the complexity behind it, and how smart economic solutions are critical.

Brazilian researchers analyzed air pollution in metropolitan São Paulo in 2019-20 when mobility restrictions and social distancing applied in the southern hemisphere’s largest city. Even so, the daily average exceeded the World Health Organization’s air quality standard on 75 days.

A study conducted at the University of São Paulo’s Optics and Photonics Research Center in Brazil showed a change in the bacterium’s sensitivity after five applications.The research group analyzed patient samples containing Staphylococcus aureus, a bacterium that causes a range of diseases from skin infections to pneumonia.
