Research indicates association between high consumption of ultra-processed foods and increased risk of dementia

(American Academy of Neurology) – People who eat the highest amounts of ultra-processed foods such as soft drinks, chips, and cookies may have a higher risk of developing dementia than those who eat the lowest amounts, according to a study published in the July 27 online issue of Neurology. Researchers also found that replacing ultra-processed foods in a person's diet with unprocessed or minimally processed foods was associated with a lower risk. The study does not...

Work at Ukraine grain ports resumes after deal, officials say

Ukraine says work has started at three ports aimed at forming "green corridors" to allow grain exports, the BBC reports. A spokesperson for the Odesa military administration said naval teams will build routes out of southern ports in Odesa, Chornomorsk, and Pivdennyi. Once the routes are established, "caravans" of ships led by Ukrainian naval vessels will sail through the Black Sea, Serhiy Bratchuk said. Kyiv and Moscow struck a deal to allow the grain exports last week. Under...

Mayo Clinic researchers pinpoint genetic variations that could help determine susceptibility to COVID-19

Researchers at Mayo Clinic's Center for Individualized Medicine have discovered key human genomic signatures that could help explain why COVID-19 is severe in some people and mild in others. After analyzing volumes of diverse worldwide DNA sequence data, the scientists identified mutations in two human proteins that might sway the course of SARS-CoV-2 — the virus responsible for COVID-19. Their study reveals that variants in the genes for ACE2 and TMPRESS2 can lead to an increase or...

Gazprom to make another deep cut in gas delivery to EU

Russian energy giant Gazprom says it will once again drastically cut gas supplies to the EU through its main pipeline due to maintenance work. Gazprom said stopping another turbine at the Nord Stream 1 pipeline would cut daily gas delivery to 20%, halving the current level of supply. The German government said there was no technical reason to limit gas supply. It is likely to make it more difficult for EU countries to replenish their stores of...

How to tell if AI is working the way we want it to

(Massachusetts Institute of Technology) – About a decade ago, deep-learning models started achieving superhuman results on all sorts of tasks, from beating world-champion board-game players to outperforming doctors at diagnosing breast cancer. These powerful deep-learning models are usually based on artificial neural networks, which were first proposed in the 1940s and have become a popular type of machine learning. A computer learns to process data using layers of interconnected nodes, or neurons, that mimic the human brain. As...

International study examines prevalence of long COVID in children

(Ann & Robert H. Lurie Children's Hospital of Chicago) – Nearly 6% of children who presented to the emergency department (ED) with COVID-19 reported symptoms of long COVID 90 days later, according to a study conducted in eight countries and published in JAMA Network Open.
