Maintaining connections between natural habitats may support beneficial microbes that help wildlife defend against disease. In a new study of tropical amphibians, a team led by Penn State biologists found that amphibians in connected natural forests and aquatic habitats were more likely to host beneficial skin microbes that inhibit a deadly fungal pathogen. But when these habitats become spatially separated due to planted crops, infrastructure development or other human land use, those [...]

The accumulation of fat in the abdominal region, especially visceral fat (fat that accumulates between organs), significantly increases the risk of stress urinary incontinence in women. A study conducted at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, and supported by FAPESP (projects 13/00798-2 and 22/16910-5 ), identified this region as the one most strongly associated with involuntary urine leakage, surpassing total body fat. The results [...]

On March 27, 1938, Italian physicist Ettore Majorana vanished without a trace at the age of 31. Intellectually brilliant yet emotionally conflicted, Majorana was considered a genius. His professor, Enrico Fermi, winner of the 1938 Nobel Prize in Physics, placed him on the same level of greatness as Isaac Newton (1642–1727). The previous year, in 1937, Majorana published the article "Teoria simmetrica dell'elettrone e del positrone." It was one of the few texts by Majorana that survived [...]

A Brazilian study based on postmortem toxicological analyses found that 53% of violent death victims had alcohol or drugs in their systems shortly after death. The study examined 3,577 cases in Belém (North), Recife (Northeast), Vitória (Southeast), and Curitiba (South), representing the four regions of the country. "The goal was to produce standardized and comparable data on the role of psychoactive substances in deaths from external causes in Brazil," says Henrique Silva Bombana , a [...]

A study conducted at the University of São Paulo (USP) in Brazil reveals that tissues such as the tonsils and adenoids can serve as hiding places for the rhinovirus, which causes the common cold and is responsible for most respiratory infections worldwide. Using samples from 293 children who underwent surgery to remove these tissues, the study showed that the pathogen can infect immune cells known as lymphocytes and remain there for long periods without causing symptoms. This allows the [...]

A breakthrough sugarcane protein may soon protect teeth like natural saliva—even when the body can’t. Summary: Scientists have created an artificial saliva using a sugarcane protein that can protect teeth and fight bacteria. The key ingredient, CANECPI-5, binds directly to enamel, forming a shield against acids that cause decay. Early tests show it works even better when paired with fluoride and xylitol, significantly reducing damage to teeth. The innovation could be especially [...]

A study conducted at the Institute of Science and Technology of São Paulo State University (ICT-UNESP) in São José dos Campos, Brazil, shows that Moringa oleifera, also known as moringa or white acacia, has the potential to remove microplastics from water. The study was published in the journal ACS Omega, published by the American Chemical Society. Moringa is native to India and well-adapted to various tropical countries. It is used for a variety of purposes, such as food, through [...]
