Caecilians are limbless amphibians that, to the untrained eye, can be easily mistaken for snakes. Though caecilians are only distantly related to their reptilian cousins, researchers in a study appearing July 3 in the journal iScience describe specialized glands found along the teeth of the ringed caecilian (Siphonops annulatus), which have the same biological origin and possibly similar function to the venom glands of snakes. If further research can confirm that the glands contain venom, [...]

A protein derived from the saliva of the tick Amblyomma sculptum has been successfully used by researchers at the Butantan Institute in São Paulo, Brazil, to treat skin cancer (melanoma) in horses. The results of the study are described in the journal Scientific Reports. The principal investigator for the project is Ana Marisa Chudzinski-Tavassi, who leads the Center of Excellence in New Target Discovery (CENTD), an Engineering Research Center (ERC) established at the Butantan Institute [...]

The firm plans to produce ELISA kits that will detect antibodies against the novel coronavirus in blood serum. Researchers at Biolinker, a biotech startup based in São Paulo, Brazil, are developing a low-cost high-performance COVID-19 diagnostic test using only locally sourced inputs. Biolinker is incubated at the University of São Paulo’s Center for Innovation, Entrepreneurship and Technology (CIETEC), jointly run by the University of São Paulo (USP) and the [...]

In a review article published in the American Journal of Physiology, Brazilian researchers present scientific evidence on the impact of short periods of inactivity on the cardiovascular system and recommend exercise to stay fit at home during the pandemic The adverse side effects of the social isolation measures implemented to combat COVID-19 include an increase in sedentary behavior and physical inactivity, which can contribute to a deterioration in cardiovascular health even in the short [...]

Researchers at São Paulo State University (UNESP) in Araçatuba, Brazil, have developed a computational tool that acts like a "COVID-19 accelerometer," plotting in real time the rate at which growth is accelerating or decelerating in more than 200 countries and territories. Available free of charge online, the application automatically loads the most recent notified case numbers from the European Center for Disease Prevention and Control (ECDC), updated daily, and [...]

The international trade in timber, tobacco, cocoa, coffee and cotton accounts for a high proportion of malaria risk in exporter countries, according to a collaborative study by scientists in Brazil and Australia published in Nature Communications. A paper recently published in Nature Communications is the first to show a connection between demand from certain developed countries for agricultural commodities and the growing risk of malaria in the countries that supply those goods. The study was [...]

Exposure to ultraviolet (UV) radiation is a risk factor for skin cancer and other diseases. The risk increases when sunlight, the natural source of UV radiation, is combined with artificial sources such as UV lamps for medical therapy, among others. Detecting and measuring UV exposure in different environments was the scope of a research project conducted in Brazil at the São Paulo Federal Institute of Education, Science and Technology (IFSP) in collaboration with the University of [...]

Created at the University of São Paulo’s Engineering School, the machine costs approximately 7% as much as a conventional ventilator and can be freely manufactured by companies that obtain approval from the national health surveillance authority A group of researchers at the University of São Paulo’s Engineering School (POLI-USP) in Brazil have developed a mechanical ventilator that costs only approximately 7% as much as a conventional ventilator. Called Inspire, it [...]

The same procedure will be extended to the entire Atlantic Rainforest biome, remnants of which are located on the coast of 17 Brazilian states The Atlantic Rainforest has been so savagely clearcut and burned over several centuries that only approximately 12% now remains. Nevertheless, it is still one of the planet’s largest repositories of biodiversity, and counter to a process that appeared irreversible, forest cover in the biome has begun to grow back in recent decades. To confirm [...]
