A team of scientists from the Center for Innovation in New Energies (CINE), working at the State University of Campinas (UNICAMP) in Brazil, has developed a new method for purifying materials used in green hydrogen production. The process is described as simple, low-cost, and environmentally friendly, and has significantly improved the performance of a key material used in hydrogen generation, reports Agencia FAPESP. The material in focus is mullite-type bismuth ferrite (Bi₂Fe₄O₉), [...]

In a discovery that could dramatically increase the efficiency of biofuel production, Brazilian researchers have identified a new enzyme that makes it much easier to break down cellulose, the main component of plant cell walls. This breakthrough could pave the way for large-scale production of second-generation ethanol, a cleaner alternative fuel made from agricultural waste like sugarcane bagasse and corn stalks, reports PHYS ORG. The research, led by the Brazilian Center for Research in [...]

WASHINGTON: 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 [...]

There’s something deeply unsettling about walking through a modern supermarket aisle. Shelf after shelf is lined with brightly packaged, ready-to-eat goods that promise convenience, taste, and even nutrition. But hidden behind the flashy labels and seductive flavors is a bitter truth: these ultraprocessed foods, or UPFs, are slowly but steadily becoming one of the biggest threats to global health. And it’s no longer just a theory, it’s now backed by strong, sobering [...]

Difficulty finding words or the habit of substituting them with others that are similar semantically, such as knife and cutter, or phonologically, such as knife and wife, are usually the first symptoms of a type of dementia known as primary progressive aphasia (PPA). Another sign is a subtle difficulty in forming sentences, evidenced by verbal and nominal agreement errors that have never been made before, or reversal of word order, for example. Writing errors (dysgraphia) and reading [...]

Washington DC: 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 [...]

A recent study, published in the American Journal of Preventive Medicine, has highlighted a disturbing trend linking the consumption of ultraprocessed foods (UPFs) to a significant rise in premature deaths across eight countries: Australia, Brazil, Canada, Chile, Colombia, Mexico, the United Kingdom, and the United States. The research reveals that as the share of UPFs in individuals' total energy intake increases, so does the risk of dying prematurely. This study, which analyzes data [...]

One of the earliest signs of a dementia variant called primary progressive aphasia (PPA) is trouble finding the right words or unintentionally swapping them with others—either similar in meaning (like "knife" and "cutter") or in sound (such as "knife" and "wife"). Individuals may also begin to struggle with sentence structure, making grammar mistakes or reversing word order in ways they hadn't before. As the condition progresses, reading [...]
