Global study links consumption of ultraprocessed foods to preventable premature deaths
Publicado em 29 de abril de 2025
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 reinforces the call for global action to reduce UPF consumption, supported by regulatory and fiscal policies [...]

The Oldest Ant Ever Discovered Found Fossilized In Brazil
Publicado em 24 abril 2025A 113-million-year-old hell ant that once lived in northeastern Brazil is now the oldest ant specimen known to science, finds a report publishing in the Cell Press journal Current Biology on April 24. The hell ant, which was preserved in limestone, is a member of Haidomyrmecinae -- an extinct subfamily that only lived during the Cretaceous period. These ants had highly specialized, scythe-like jaws that they likely used to pin or impale prey. "Our team has discovered a new fossil ant [...]ver notícia -
Eight or more drinks per week linked to signs of injury in the brain
Publicado em 10 abril 2025Heavy drinkers who have eight or more alcoholic drinks per week have an increased risk of brain lesions called hyaline arteriolosclerosis, signs of brain injury that are associated with memory and thinking problems, according to a study published on April 9, 2025, online in Neurology ® , the medical journal of the American Academy of Neurology The study does not prove that heavy drinking causes brain injury; it only shows an association. Hyaline arteriolosclerosis is a condition that [...]ver notícia -
Recycled cements drive down emissions without slacking on strength
Publicado em 21 março 2025Giving a second life to construction materials after demolition, engineers at the University of São Paulo and Princeton have developed an approach for recycling cement waste into a sustainable, low-carbon alternative that is comparable in performance to the industry standard. In addition to lowering the carbon intensity of the cement and concrete industry, the process could enable new uses for construction and demolition waste, of which concrete is a significant component. In 2018 in [...]ver notícia -

AI to diagnose 'invisible' brain abnormalities in children with epilepsy
Publicado em 24 fevereiro 2025MELD Graph is an AI tool that could drastically change the care for 30,000 patients in the UK and 4 million worldwide with one cause of epilepsy, researchers say. The study, published today in JAMA Neurology by a team at King's College London and University College London (UCL), shows how the tool significantly improves the detection of focal cortical dysplasia's (FCDs) which is a leading cause of epilepsy. Researchers say the tool will speed up diagnosis times, get patients the [...]ver notícia -
Glass fertilizer beads could be a sustained nutrient delivery system
Publicado em 22 fevereiro 2025Agricultural fertilizers are critical for feeding the world's population, restoring soil fertility and sustaining crops. Excessive and inefficient use of those resources can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers reporting in ACS Agricultural Science & Technology have addressed those challenges with glass fertilizer beads. The beads control nutrient release, and the researchers say [...]ver notícia -
Warding Off Superbugs with a Pinch of Turmeric
