The 2023-24 El Niño brought simultaneous extreme heat and drought to 75% of tropical forests for months on end. Now, a new study indicates that those conditions may have been a preview of annual norms for future tropical forests just a couple of decades away, even under moderate-emissions scenarios, and even outside of El Niño years.

During the 2023–2024 El Niño, about 75% of the world's tropical forest areas experienced at least six months of unprecedented simultaneous drought and heat. According to a study due to be published in the October 7 issue of the journal Earth's Future, this scenario offers more than just a snapshot of an extreme event; it offers a preview of the "new normal" for the next two decades if greenhouse gas emissions are not reduced. The Amazon is the region that is most vulnerable to [...]

Sao Paulo [Brazil], October 1 (ANI): Brazil is expanding the use of biological control technologies in agriculture, with the Advanced Research Center on Biological Control (SPARCBio) in Piracicaba developing solutions aimed at managing pests and diseases in tropical farming. The centre, supported by the University of Sao Paulo's Luiz de Queiroz School of Agriculture (ESALQ/USP), the Sao Paulo Research Foundation (FAPESP) and biological control company Koppert, focuses on developing [...]

Molecules known for their anti-cancer activity have proven effective in combating Plasmodium falciparum, the parasite that causes malaria. Researchers at the University of São Paulo's School of Pharmaceutical Sciences (FCF-USP) in Brazil also investigated how differences in the structure of these molecules affect their impact on the parasites. This research paves the way for the development of more effective drugs. According to estimates by the World Health Organization (WHO), malaria [...]

When it comes to balancing hormonal changes during the transition to menopause, less can be more. Researchers at the University of São Paulo (USP) in Brazil demonstrated this when testing an alternative strategy to conventional therapy. Rather than replacing estrogen entirely, the team activated only one type of estrogen receptor in the cells. This approach achieved a broad and beneficial metabolic effect without stimulating the growth of reproductive tissues, such as the uterus and breasts. [...]

You have been lifting weights for weeks, and the scale still has not budged. A new animal study points to a possible explanation. The fat cells themselves may already be shrinking, even when body weight has not changed. Researchers at the State University of Campinas (UNICAMP) in Brazil put obese mice through seven days of strength training. The team tracked visceral fat, fat cell size and the proteins that break fat down. The study in Life Sciences found all three shifted, while [...]

Brazilian researchers have developed a biodegradable, starch-based sensor that changes color when moisture enters food packaging. Thanks to the addition of cobalt chloride, the smart device changes color from blue to pink as moisture levels rise or fall. This technology enables consumers and manufacturers to easily monitor the quality and crispness of foods, such as cookies, with the naked eye or via a cell phone screen, eliminating the need for complex equipment. The research was led by [...]
