The largest genetic study on anxiety disorders to date reveals new biological mechanisms behind anxiety. It can help to find new ways to develop more precise therapies. People with an anxiety disorder usually have a hard time with this. (Image: Fandom / Adobe Stock / KI-generiert) Around one in four people suffer from an anxiety disorder at some point in their lives. These include panic disorder with sudden, severe anxiety attacks, generalised anxiety disorder, in which sufferers [...]

A team of researchers at the State University of Campinas (UNICAMP) has found a simple yet effective way to boost the performance of low-cost materials by deliberately introducing structural defects. In a recent study published in Electrochimica Acta, scientists from the Center for Innovation on New Energies (CINE) significantly enhanced the efficiency of inexpensive catalysts by engineering vacancies, or “defects,” into their structure. The approach offers a cost-effective route to [...]

Despite greater muscle mass of transgender women 1-3 years after hormone therapy Evidence is of variable quality, but doesn't back inherent athletic advantage theories Transgender women might have more muscle mass than cisgender women 1 to 3 years after hormone therapy, but their physical fitness is comparable, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine. While the current body of evidence is of variable [...]

Many post-surgical heart injuries go unnoticed, but cardiologist input can change outcomes. In a recent study published in the European Heart Journal, researchers analyzed data from more than 1,000 patients who developed perioperative myocardial injury to explain the potential mortality benefits of including a cardiologist in non-cardiac procedures, particularly for high-risk patients. Study findings revealed that cardiologists can substantially improve outcomes, with patients who [...]

Brazilian researchers who have pooled together past research on the topic say that, despite larger muscle mass, transgender women have comparable physical fitness levels to those of cisgender women. Previous studies suggested that hormone therapy might alter body composition in transgender people and, as a result, change their functional performance and physical advantages, but the authors of this new study suggest that this may not be the case. The team says that, while transgender women had [...]

Transgender women might have more muscle mass than cisgender women 1 to 3 years after hormone therapy, but their physical fitness is comparable, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine. While the current body of evidence is of variable quality, and doesn't look at the potential for any advantage at the elite athlete level, it doesn't back up prevailing theories about the inherent athletic advantage of [...]

Brazilian researchers have developed a synthetic compound that has the potential to treat malaria and block its transmission. The new molecule acts during three phases of the disease cycle, eliminating the asexual form of the parasite from human blood and liver, and preventing transmission to mosquitoes. This multi-stage approach is a more comprehensive strategy for combating the disease. "An important difference with this compound is its effectiveness against Plasmodium vivax, the [...]

A multidisciplinary team of Brazilian researchers argues in an article published in the British Medical Journal that health systems in the Brazilian Amazon must be redesigned in light of climate change, extreme weather events, and food insecurity. The researchers propose that this redesign take into account traditional knowledge and the specific needs of local communities. With COP30 taking place in the Amazon and the recent development of a national health and climate plan by the [...]

Breakthrough USP Genetic Study Illuminates Brazilian Supercentenarians' Longevity Secrets Brazilian researchers at the University of São Paulo (USP) have made headlines with a pioneering publication that delves into the genetic and immunological underpinnings of extreme human longevity. Published on January 6, 2026, in the journal Genomic Psychiatry, the viewpoint article titled "Insights from Brazilian Supercentenarians" highlights why the country's diverse population offers [...]
