Green tea has long been valued for its medicinal and antioxidant qualities. It has been extensively investigated for its role in metabolic health, particularly in conditions such as obesity and type 2 diabetes. Recent research supported by FAPESP (19/10616-5, 21/08498-4 and 23/11295-3) has provided new insights into how green tea works and showed that treatment with the beverage lowered body weight and markedly improved glucose sensitivity and insulin resistance in obese mice. These findings [...]

Researchers employed a novel approach to analyze data from a large sample of residents across four state capitals in different regions of Brazil, contributing to the development of preventive strategies for this type of tumor. Sugar added to food may be the “villain” in the relationship between stomach cancer and an unhealthy diet, while salt increases the risk of tumors even in individuals with otherwise healthy eating habits. This conclusion comes from a study conducted in [...]

The Brazilian Atlantic Rainforest is filled with the ear-piercing 'screams' of a tiny amphibian in distress, but until now, we humans have been oblivious to their cries. For the first time, researchers have recorded South American frogs crying out at a frequency that totally bypasses the human ear – but which would be quite unpleasant to animals with the right kind of receivers. The leaf litter frog (Haddadus binotatus) is the most abundant species of frog in the forest [...]

The large size variation among cetacean species, including dolphins, whales, and porpoises, is largely explained by the activity of specific gene regions, according to a recent study by scientists from Brazil's University of Campinas Institute of Biology (IB-UNICAMP). Blue whales (Balaenoptera musculus), for example, can grow up to a giant 30 meters (98 feet) long while the bottlenose dolphin (Tursiops truncates) usually doesn't get longer than 3.5 meters. Not only does the new [...]
