Neurons and white blood cells differ greatly in shape, function, and location within the body. However, researchers at the University of Sao Paulo (USP) in Brazil discovered that certain genes are equally dysregulated in both cell types in people with depression. This finding not only reinforces the systemic nature of depression, which has repercussions that extend beyond mental health, but also paves the way for future blood tests that can identify the type and severity of depression. The [...]

A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI2) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit information in the terahertz frequency range. Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM), in partnership with colleagues from the University of Lille (France) and other international institutions, have studied this technology and [...]

According to research published in Nutrition and Cancer, a team at São Paulo State University investigated whether vitamin D supplementation could support chemotherapy in breast cancer patients. The study, backed by FAPESP, followed 80 women aged over 45 undergoing pre-surgical chemotherapy at a teaching hospital in Brazil. Instead of focusing solely on clinical outcomes, the researchers also underscored the accessibility of the intervention, noting that many therapies designed to [...]

Something exciting is brewing in the skincare world. A new study suggests that a byproduct of beer production could make sunscreens more effective at blocking harmful ultraviolet B rays, which are responsible for sunburns. The finding could be significant, as studies have shown that many products on store shelves don’t deliver the level of protection they claim. Just last week, a Consumer Reports analysis of more than 100 sunscreens found that a majority delivered average Sun [...]

A study shows that small doses of the antibiotic minocycline may help treat panic disorder. Experiments conducted at São Paulo State University (UNESP) in mice and at the Federal University of Rio de Janeiro (UFRJ) in humans showed that minocycline has a similar effect to clonazepam, the most commonly prescribed anti-panic medication and best known by its brand name, Rivotril. The study is published in the journal Translational Psychiatry. The antibiotic doses required to treat panic [...]

A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus that causes COVID-19. The work is published in the journal Scientific Reports. Why this Brazilian tree was chosen The species was chosen because the research group led by Jairo Kenupp Bastos, a pharmacist and professor at the Ribeirão Preto School of Pharmaceutical [...]

Tropical forests are among the world's most important carbon sinks. A new study by the Technical University of Munich (TUM), the University of Vienna, and Brazil's National Institute for Amazonian Research suggests that even small understory trees can temporarily store more CO₂ as atmospheric CO₂ levels rise. However, their long-term capacity to sequester carbon may be constrained by nutrient limitations, potentially reducing this ability. The Amazon forest is one of the tipping [...]

A study conducted on an animal model by researchers at the Federal University of São Paulo (UNIFESP) in Brazil demonstrated that swimming is more effective than running in promoting healthy heart growth and improving the strength with which the heart muscle (myocardium) contracts. "Swimming and running are two excellent ways to improve cardiorespiratory health and protect the heart muscle, but we wanted to know if one could be even more beneficial than the other. We found that, although [...]

Swimming may do more for your heart than running, according to new research. But there’s an important catch: the findings come from animal studies, not humans. In a recent study published in Scientific Reports, researchers found that mice that swam regularly showed greater improvements in heart structure and function compared to those that ran. The study was led by scientists at the Federal University of São Paulo and supported by the São Paulo Research [...]
