Scientists have discovered a new phase of water — adding to liquid, solid and gas — know as “superionic ice.” The “strange black” ice, as scientists called it, is normally created at the core of planets like Neptune and Uranus. In a study published in Nature Physics, a team of scientists co-led by Vitali Prakapenka, Read more about Scientists discover new phase of water, known as “superionic ice,” inside planets[…]

No one knows why some people age worse than others and develop diseases -such as Alzheimer’s, fibrosis, type 2 diabetes or some types of cancer- associated with this aging process. One explanation for this could be the degree of efficiency of each organism’s response to the damage sustained by its cells during its life, which Read more about Researchers design antibodies that destroy old cells, slowing down aging[…]

Daily exposure to phthalates, a group of chemicals used in everything from plastic containers to makeup, may lead to approximately 100,000 deaths in older Americans annually, a study from New York University warned Tuesday.

The fight against malaria, one of the world’s worst diseases for decades, is likely to get much easier as the World Health Organization has endorsed the wide use of a malaria vaccine developed by GlaxoSmithKline, the first ever to win such approval. The vaccine will be recommended for children in sub-Saharan Africa and other high-risk Read more about WHO Endorses ‘Breakthrough’ Childhood Vaccine For Malaria[…]

Carlene Knight’s vision was so bad that she couldn’t even maneuver around the call center where she works using her cane. But that’s changed as a result of volunteering for a landmark medical experiment. Her vision has improved enough for her to make out doorways, navigate hallways, spot objects and even see colors. Knight is Read more about CRISPR Gene-Editing Experiment using direct injection Partly Restores Vision In Legally Blind Patients[…]

A relatively new type of computing that mimics the way the human brain works was already transforming how scientists could tackle some of the most difficult information processing problems. Now, researchers have found a way to make what is called reservoir computing work between 33 and a million times faster, with significantly fewer computing resources Read more about Scientists develop the next generation of reservoir computing[…]

When two substances are brought together, they will eventually settle into a steady state called thermodynamic equilibrium; examples include oil floating on top of water and milk mixing uniformly into coffee. Researchers at Aalto University in Finland wanted to disrupt this sort of state to see what happens—and whether they can control the outcome. […] Read more about Physicists make square droplets and liquid lattices[…]

An enormous randomized trial of communities in Bangladesh seems to provide the clearest evidence yet that regular mask-wearing can impede the spread of the covid-19 pandemic. The study found that villages where masks were highly promoted and became more popular experienced noticeably lower rates of covid-like symptoms and confirmed past infections than villages where mask-wearing Read more about Masks Lead to Less Covid-19, Massive Study Finds[…]

Reddit has finally cracked down on COVID-19 misinformation following growing calls to act, although it probably won’t satisfy many of its critics. The social site has banned r/NoNewNormal and quarantined 54 other COVID-19 denial subreddits, but not over the false claims themselves. Instead, it’s for abuse — NoNewNormal was caught brigading en masse (that is, Read more about Reddit offers a non-response to uproar over COVID-19 misinformation[…]
