Having a panic attack? Keep calm and get a move on. Panic attacks — sudden, overwhelming feelings of fear that trigger physical symptoms — are quite common. Over 28% of adults will experience at least one of these episodes at some point, with 2% to 3% of the US population having panic attacks often enough that they are believed to have panic disorder. Panic disorder is typically treated with cognitive behavioral therapy (CBT) and/or antidepressants. Now, researchers in Brazil [...]

A study conducted in Brazil by researchers at the Federal University of São Paulo (UNIFESP) and the ABC Medical School (FMABC) warns that the prolonged use of proton pump inhibitors (PPIs) can impair nutrient absorption. PPIs are a class of drugs that includes medications such as omeprazole, pantoprazole, and esomeprazole. They are used to treat gastric disorders. Using them inappropriately for periods longer than recommended by physicians can cause nutritional deficiencies, such as anemia, [...]

Using the skin of an Amazonian fish known as tambatinga as the raw material, researchers at the University of São Paulo (USP) and EMBRAPA Pecuária Sudeste—a decentralized unit of the Brazilian Agricultural Research Corporation (EMBRAPA) located in São Carlos, São Paulo state—have developed a biofilm that can be used in food packaging. A sustainable source of biopolymer collagen The tambatinga, the result of crossbreeding the female tambaqui (Colossoma macropomum) and the male [...]

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 relatively simple statistical analysis method can more accurately predict the risk of landslides caused by heavy rain, according to a study coordinated by Brazilian researchers affiliated with the Institute of Mathematical and Computer Sciences at the University of São Paulo (ICMC-USP) in São Carlos and the National Institute for Space Research (INPE). The researchers have validated their strategy based on a real event. In February 2023, the municipality of São Sebastião, on the [...]

The chytrid fungus (Batrachochytrium dendrobatidis), or Bd for short, is considered one of the causes of the worldwide decline in amphibian populations. In recent years, researchers have identified different genetic strains of the fungus that causes chytridiomycosis in various parts of the world. This has already led to the decline of at least 500 species of anuran amphibians, including toads and frogs. The global spread of the fungus is attributed to the trade of bullfrogs (Aquarana [...]

Longevity experts have discovered why so many people in Brazil live past the age of 110, making them super-centenarians. Scientists studying Brazil's unusually high number of supercentenarians – people who live far beyond the age of 100 – have made a remarkable discovery about how their supercharged immune systems help keep them healthy into extreme old age. Brazil is home to a disproportionate number of people who live past 110, making it a uniquely valuable setting for longevity [...]

A research team led by Chalmers University of Technology, Sweden, has presented a new way to produce hydrogen gas without the scarce and expensive metal platinum. Using sunlight, water and tiny particles of electrically conductive plastic, the researchers show how the hydrogen can be produced efficiently, sustainably and at low cost. The work of exploring how hydrogen can be produced both efficiently and environmentally sustainably—without platinum—has been led for several years by [...]

A Viewpoint published in Genomic Psychiatry by Dr. Mayana Zatz and colleagues at the Human Genome and Stem Cell Research Center, University of São Paulo, examines why Brazil represents one of the most valuable yet underutilized resources for understanding extreme human longevity. The synthesis draws upon the team's ongoing research with a nationwide cohort of long-lived individuals while contextualizing recent advances in supercentenarian biology. Where genetic diversity meets [...]
