An analysis of 429 specimens belonging to 39 species representative of the diversity of Polistes in the Americas confirmed the inverse of Bergmann’s rule by pointing to larger body size for species occurring in or near the tropics compared with species inhabiting higher latitudes.

Researchers partnering with the City of Guarujá (São Paulo state) conducted a study that found a high level of contamination on Perequê Beach, with plastics and cigarette butts predominating. The results will be useful for policymakers to implement measures that can mitigate the problem.

A recent study conducted by scientists at ESPOL has unveiled the biotechnological potential of microorganisms from Antarctica. In this remote continent, where life thrives under extreme conditions, researchers isolated 77 microbial strains from 162 cultures, identifying 49 species, predominantly actinomycetes (66.23%). Sampling conducted at the Great Wall and Henryk Arctowski stations revealed a rich diversity of microorganisms, especially in areas covered with mosses and lichens, where organic matter appears to support their proliferation. 

Plant-based pigment with antioxidant and anticancer properties breaks down easily in the gastrointestinal tract and under adverse environmental conditions. To avoid the problem, researchers at the University of São Paulo inserted the compound into pectin-coated nanoparticles, enhancing its bioavailability.

The study was conducted at the Federal University of São Paulo and involved 144 diabetic patients, who were treated with monochromatic infrared light and physical therapy.

The inventory identified some 1,000 landslide points in São Sebastião (São Paulo state, Brazil). The research group is now using airborne laser scanning and other data inputs to create a methodology capable of more precise results.

The strategy developed at the University of São Paulo uses magnetic nanoparticles that bind to tiny plastic particles and permit their removal with the aid of a magnet.

This particular strain of Klebsiella pneumoniae had previously been detected in the United States. The bacterium frequently causes infections in hospitals, is not eliminated by any existing antibiotic, and is especially dangerous for people with low immunity.

There’s no cure for a fungal disease that could potentially wipe out much of global banana production. Widespread adoption of cement paths, disinfection stations, and production strategies could net 3-4 USD of benefits for each dollar invested in Colombia.
