Combination of drugs produces promising results in combating cancer and will be clinically trialed in Europe
Brazilian researchers innovated by stimulating tumor cells so much that they became stressed and could survive only by behaving like healthy cells. The results of the study were so promising that the researchers plan to hold clinical trials with patients, to be conducted in the Netherlands before the end of 2024.

Orion will be the world’s first maximum biosafety lab linked to a synchrotron light source
Scheduled to start operating in 2028 at the Brazilian Center for Research on Energy and Materials (CNPEM) in Campinas (São Paulo state), the lab will enable researchers for the first time in Latin America to study viruses classified as class 4, the highest category of biological risk.

Important region of marine ecosystem in Southwest Atlantic is shallower than expected, study finds
Researchers at the Federal University of São Paulo determined for the first time the vertical limits of the subtropical ocean region off the South American coast. They found that the upper limit of the mesotrophic zone, previously assumed to be 30 meters below the surface, was in fact in much shallower waters.

Novel nanomaterial keeps more phosphorus available in soil than commercial fertilizer
The novel compound was developed in the lab but can be produced with technology already used by the industry, facilitating scale-up. It fixes phosphorus in the soil for future crop cycles and requires fewer applications. The researchers are seeking partners to mass-produce it for use in large-scale experiments.

Mild COVID-19 can cause long-term cognitive losses
A study involving 302 volunteers showed that although the damage caused by SARS-CoV-2 was most intense among those who had severe COVID-19, some exhibited memory loss and attention deficit more than 18 months after being infected, even though they had not needed to be hospitalized.

Study proposes changes to simplify legislation on Atlantic Rainforest biome and enhance conservation
Lack of a method to classify forest succession stages in the applicable legislation allows for destruction of forest areas that provide important ecosystem services. The authors propose changes to make measurements more accurate and eliminate a step in permit applications that is ineffective and costly for landowners.
