Research published in the journal Scientific Reports shows that a peptide (molecule derived from a protein) developed by Brazilian scientists, called Rb4, was effective in combating the progression of cancer in an animal model —especially severe melanoma—, being a promising agent for the treatment of drug resistant tumors. In preclinical, in vitro and in vivo phases, the work provided evidence that Rb4 triggers necrosis in murine melanoma cells (from mice). In addition, the [...]

Light-based therapies, such as ​​, combined with techniques such as laser and negative pressure are showing good results in the rehabilitation of patients with post-Covid-19 sequelae, including those who had muscle, joint, neurological, dermatological and pulmonary injuries. The promising data were presented in an article published in the journal Laser Physics Letters. The research is being conducted by groups from the Optics and Photonics Research Center (CEPOF) and the National [...]

Together, in 2021, the institutions graduated 5,600 masters and 3,623 doctors, in a total of 9,223 degrees, the lowest number in the last ten years — in 2011, there were 9,925. USP, Unicamp and Unesp are responsible for training almost a third of the masters and doctors in Brazil. Although there are no national figures available on the total number of graduates in other educational institutions in the last two years, the drop in the three most representative universities alerts us to a [...]

There is a correlation between coping with Covid-19 and environmental disasters in Brazil, and that is not good. A study carried out by a researcher from the National Center for Monitoring and Alerts for Natural Disasters (Cemaden) showed that, in addition to the discontinuity of resources, there is still a basic problem regarding the need for policies for urban development that reduce the spatial distribution of vulnerability. The data were presented in the journal Sustainable Cities and [...]

A study carried out in the city of Manaus showed that, through a chemical process known as oxidation, small aerosols expelled by factories or car exhausts, for example, grow very quickly, reaching size up to 400 times larger. And this interferes with the formation of raindrops. “Understanding the mechanisms of cloud formation and rainfall in the Amazon is a major challenge due to the complexity of non-linear physical-chemical processes in the atmosphere”, explains Paulo Artaxo, a [...]

EllaLink, a fiber optic cable that directly connects Fortaleza, Ceará, to the city of Sines, on the coast of Portugal, was inaugurated at the end of August by the BELLA scientific consortium. As part of the opening procedures, the team from the São Paulo Regional Analysis Center (SPRACE), a project linked to the Scientific Computing Center of the São Paulo State University (NCC-Unesp), conducted a series of experiments to demonstrate the potential of the new cable , which [...]

A Brazilian study published in Communications Earth & Environment magazine reveals how fires interfere with the formation of rain clouds in the Amazon. According to the authors, the small solid or liquid particles released into the atmosphere by the flames – also known as aerosols – make it difficult to freeze cloud droplets when the atmosphere is humidified, but they can also favor freezing when the atmosphere is drier. This alters the natural functioning of clouds and their [...]

A vaccine in the form of an easy-to-apply, low-cost nasal spray, long-lasting protection even against variants and capable of blocking the action of the new coronavirus even in the nose, where infections begin. This is the objective of a project being developed by a group of researchers from the University of São Paulo (USP), in partnership with the Federal University of São Paulo (Unifesp) and the Oswaldo Cruz Foundation (Fiocruz). The new immunizing agent, still in the early [...]

An international study carried out in ten cities, including São Paulo, reveals that a relatively short period in places with a high concentration of pollution is enough to expose car drivers and passengers to significant doses of fine inhalable particles – those that, due to their smaller diameter. that 2.5 millionths of a meter (PM2.5) can reach the pulmonary alveoli and cause even more damage to the body. According to the study, therefore, spending too little time in bottling [...]
