The study offers new dating for the site, estimating it was active between 1,300 and 500 years ago, rather than the previously thought 1,170 to 900 years ago. Contrary to previous beliefs, the sambaqui builders at the Galheta IV archaeological site [...]ver notícia -
Taxpayer-Funded Research Investigated How “Populist” Politicians Spread “Misinformation” During the Covid Pandemic
Publicado em 10 maio 2024(DCNF)—The federal government funded a multilateral research project investigating how “populist” politicians allegedly sowed disinformation and eroded public trust during the COVID-19 pandemic. The National Science Foundation (NSF) paid out a grant to support research investigating “how populist politicians distorted COVID-19 pandemic health communication to encourage polarized attitudes and distrust among citizens,” which made the public “more vulnerable [...]ver notícia -

The Large Magellanic Cloud isnt Very Metal
Publicado em 01 abril 2024The Large Magellanic Cloud (LMC) is the Milky Way’s most massive satellite galaxy. Because it’s so easily observed, astronomers have studied it intently. They’re interested in how star formation in the LMC might have been different than in the Milky Way. A team of researchers zeroed in on the LMC’s most metal-deficient stars to find out how different. The LMC is about 163,000 light-years away and about 32,000 light-years across. Even though it’s that large, [...]ver notícia -
We’re Swimming in Glitter: Over 8 Million Metric Tons of Tiny Plastics Found in Oceans
Publicado em 10 outubro 2023Festive glitter, a common ingredient in makeup, greeting cards, and holiday decorations, may have a darker side than its shiny surface suggests. Researchers from the University of São Paulo (USP) in Brazil have found that glitter can negatively impact aquatic organisms vital to underwater ecosystems, with several million metric tons winding up in the oceans. Popular in various products, from nail polish to Carnival costumes, glitter’s persistence isn’t [...]ver notícia -

Taurine Supplements Could be the Key to Reversing the Aging Process
Publicado em 22 julho 2022A specific nutrient could be the secret ingredient in a new anti-aging therapy. Researchers from the University of São Paulo have discovered that the amino acid taurine can help to combat the aging process. The human body produces potentially toxic byproducts called “free radicals” when cells process oxygen and food. Even though some of these molecules carry out functions essential to the body, too many free radicals can damage the cells’ internal structures, [...]ver notícia -
Researchers Create Ingredients to Produce Food by 3D Printing
Publicado em 05 dezembro 2020Food engineers in Brazil and France developed gels based on modified starch for use as “ink” to make foods and novel materials by additive manufacturing. It is already possible to produce food with a 3D printer, potentially delivering products that suit consumer preferences regarding taste, texture, cost, convenience, and nutrition. In the near future, it will be possible to produce food with personalized shapes, textures, flavors, and colors considered attractive and healthy for [...]ver notícia
