The strategy was tested at the Federal University of São Carlos. The conversion took place under ambient temperature and pressure conditions, which could enable methane, a potent greenhouse gas, to be used to produce fuel.

Brazilian researchers have developed an algorithm to identify the protozoan Trypanosoma cruzi in photographs of blood samples taken with a mobile phone camera. The low-cost method is described in the journal PeerJ and can be reproduced

The Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT) has just launched Melisa chatbot, an artificial intelligence system that provides agro-climatic forecasts. Available on Whatsapp, Facebook and Telegram, Melisa chatbot can be found and added as a friend on these social networks. Through the chat, members can ask her about what the weather will be like in the coming months, how much it will rain, and rice and corn crop yields - depending on the day the crop is sown and the variety of seed used.

Cell culture trial shows interaction between cellular protein PCNA and SARS-CoV-2 protein M. Human protein PCNA migrates from cell nucleus to cytoplasm in the presence of protein M

There was currently no specific risk algorithm for this region, so this development will allow greater accuracy in identifying people at high risk of cardiovascular disease in clinical practice.

A research group at the State University of Campinas proposes treating the solid waste produced by breweries with ultrasound before submitting it to the process of digestion by microorganisms. The strategy obtains larger amounts of methane, which can be used by the brewery itself to generate electricity and heat. The final waste can be used as crop fertilizer

There are certain skills that once we acquire them, we rarely have to relearn them, like riding a bike or looking both ways before crossing a street. Most studies on learning and long-term memory in the wild focus on a handful of animal species. Now, in a publication in Current Biology, researchers working at the Smithsonian Tropical Research Institute (STRI) share the first report of long-term memory in frog-eating bats (Trachops cirrhosus).
