In an online seminar hosted by FAPESP and the U.S. National Science Foundation, researchers presented on initiatives aimed at promoting equity in science, technology, engineering and mathematics (STEM).
As described in Scientific Reports, the study involved analysis of blood samples from volunteers infected by Plasmodium vivax, which produces forms that lie dormant in the host and can be reactivated months after treatment. The findings will help detect and diagnose these forms, with significant potential to enhance control and treatment of the disease in future.
Developed by researchers at the University of São Paulo in Brazil, the system used the port city of Santos as a sample space, and could enhance the efficiency of civil defense activities in the context of extreme weather events.
Bacteria, fungi and archaea that live in soil act as a methane sink, among other ecosystem services, but deforestation can reduce their functional diversity, Brazilian, British and American researchers warn in the journal Trends in Ecology and Evolution.
New analysis of an archaeological site near the town of Laguna refutes the theory that the ancestors of the Southern Jê replaced the people who built shell middens and burial mounds known as sambaquis for more than 5,000 years on the coast of Santa Catarina state. The results are reported in PLOS ONE.

Experiment with the semiconductor silver phosphate revealed an unprecedented mechanism for the formation of reactive oxygen species – toxic molecules that can cause the death of pathogens.
The use of photobiomodulation and an antioxidant drug called idebenone strengthened the regenerative capacity of muscle fibers in an experimental model, a study conducted at the State University of Campinas shows.
A study conducted in a medium-sized city in São Paulo state (Brazil) found that chikungunya, which has caused major epidemics in several countries, can also circulate silently in a community, with few infections for years. The researchers produced a new profile of this arbovirus, underscoring the importance of disease surveillance to predict and prepare efficiently for epidemics.
An analysis of scientific papers published in a 15-year period on molecular methods to identify elasmobranch species shows that better detection of illegal trade has not enhanced protection.
With simple audio messages and images, the Viva Vida program produced significant improvements in over-sixties living in a major city in metropolitan São Paulo (Brazil). An article on the study is published in Nature Medicine.
After 48 hours of exposure to the pesticides imidacloprid, pyraclostrobin and glyphosate, stingless bees of the species Melipona scutellaris exhibited morphological and behavioral alterations that could weaken colonies, impair pollination and adversely affect food security.
For two weeks, scientists from the University of São Paulo collected specimens of poraquês and other fish of the order Gymnotiformes aboard the vessel Comandante Gomes. The Agência FAPESP report followed the work in the field.
Historic drought in the Negro River basin and a possible inaccurate description of the distribution of Iracema caiana may be reasons why the species was not found by the DEGy Negro River Expedition. The episode describes the first collections.
The low severity of the injury, rapid medical attention and appropriate care meant that the researcher was able to return to work on the same day he was stung by a venomous fish. In the Amazon, cases often get worse because a lack of specialized care.
In preparation for the expedition down the Negro River in search of fish of the order Gymnotiformes, researchers gather more than 200 kilos of equipment and supplies for detecting, collecting and storing specimens.
The last episode of the series of reports takes stock of the journey of a group of researchers from the USP Museum of Zoology, who spent two weeks traveling along the Negro, Preto and Jauaperi rivers in the states of Amazonas and Roraima.
