A study analyzing data from nationally representative dietary surveys and mortality data from eight countries (Australia, Brazil, Canada, Chile, Colombia, Mexico, United Kingdom, and United States) shows that premature deaths attributable to consumption of ultraprocessed foods (UPFs) increase significantly according to their share in individuals' total energy intake. The new study, appearing in the American Journal of Preventive Medicine, published by Elsevier, reinforces the call for [...]

In 2017, a tragic incident unfolded in a Nevada hospital. A woman, admitted for pneumonia, tragically succumbed to multiple organ failure and sepsis. The culprit? A strain of bacteria that had developed resistance to a staggering 26 different antibiotics. These superbugs, or antibiotic-resistant bacteria, stand as one of the most pressing public health threats globally. Joining the effort to fight these deadly pathogens, researchers at Texas A&M have now shown that curcumin, the compound [...]

A formulation developed by Brazilian researchers proved effective in tests involving mice

The use of nanometric optomechanical cavities as bridges between superconducting circuits and optical fibers The ability to transmit information coherently in the band of the electromagnetic spectrum from microwave to infrared is vitally important to the development of the advanced quantum networks used in computing and communications. A study conducted by researchers at the State University of Campinas (UNICAMP) in Brazil, in collaboration with colleagues at ETH Zurich in Switzerland and [...]

Publication of a new map showing all the above-ground biomass in the Brazilian Amazon is good news in the context of the severe crisis afflicting the world’s largest contiguous tropical rain forest. Using airborne laser scanning and satellite imagery calibrated by field forest inventories and integrated by heavy-duty computer processing and machine learning, the map reflects the world’s largest survey of tropical forest biomass ever conducted. Results of the study are [...]

HOUSTON, TX — Materials with enhanced thermal conductivity are critical for the development of advanced devices to support applications in communications, clean energy, and aerospace. But in order to engineer materials with this property, scientists need to understand how phonons, or quantum units of the vibration of atoms, behave in a particular substance. “Phonons are quite important for studying new materials because they govern several material properties such as thermal [...]

Some wasps and bees are able to recognize sick nestmates by smell and can prevent their entry into the nest to avert infection of the entire colony, assuring its survival and that of the species in the long run. A study supported by FAPESP and described in an article published in the journal Environmental Science and Pollution Research shows that this recognition does not happen in paper wasps of the species Mischocyttarus metathoracicus infected by a [...]

Researchers at the Center for Development of Functional Materials (CDMF) describe in the Journal of Molecular Liquids the development of a sensor that detects metronidazole in organisms and the environment. Metronidazole is an antibiotic used in human and veterinary medicine. Accumulation of this drug in the body can result in various health problems, and levels in blood, water, meat, and milk, among others, need to be monitored. The sensor combined magnetic fluorescent multi-functional [...]

An article by researchers at the Center for Development of Functional Materials (CDMF) in Brazil describes a successful strategy to mitigate charge capacity loss in vanadium redox flow batteries, which are used by electric power utilities among other industries and can accumulate large amounts of energy. The article is published in the Chemical Engineering Journal. CDMF is a Research, Innovation and Dissemination Center (RIDC) funded by FAPESP and hosted by the Federal University of [...]
