The Nobel Prize in Physics 2022 was awarded jointly to Alain Aspect, John F. Clauser and Anton Zeilinger "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science"
Penn State researchers found that the maximum wet-bulb temperature humans can endure is lower than previously thought — about 31°C wet-bulb or 87°F at 100% humidity — even for young, healthy subjects. The temperature for older populations, who are more vulnerable to heat, is likely even lower.
MIT researchers created a portable desalination unit that can remove particles and salts simultaneously to generate drinking water. The user-friendly unit, which weighs less than 10 kilograms and does not require filters, can be powered by a small, portable solar panel.
These multicellular, cross-kingdom assemblages were more resistant to antimicrobials and removal and caused more extensive tooth decay than their single-species equivalents, according to research led by School of Dental Medicine scientists.

Our Expanded Access Program study site at Sage Integrative Health in Berkeley, California, began screening participants for MDMA-assisted therapy for PTSD in early March. Our multi-site expanded access study site for MDMA-assisted therapy for patients with treatment-resistant PTSD at the Pearl Psychedelic Institute in…
The diminished power of the immune system in older adults is usually blamed on the aging process. A new study shows that decades of inhaled particulates due to air pollution also take a toll.
Neuroscientists often use neural networks to model the kind of tasks the brain performs, in hopes that the models could suggest new hypotheses regarding how the brain itself performs those tasks. But a group of MIT researchers urges that more caution should be taken when interpreting these models.
Does explicitly acknowledging bias make us less likely to make biased decisions? A new study examining how people justify decisions based on biased data finds that this is not necessarily the case.
Holy mackerel! Could eating salmon, cod, tuna, herring or sardines keep our brains healthy and our thinking agile in middle age? New research makes this connection. Contact: Will Sansom, (210) 567-2579, sansom@uthscsa.edu SAN ANTONIO (Oct. 5, 2022) — Eating cold-water fish and other sources of omega-3 fatty acids may…
New research suggests the invasive but relatively harmless Joro spider could colonize the entire East Coast.
A new Pitt study shows that the gut microbiome of mice influences their preferred diet. The results, researchers say, could apply to humans, too.
Age-related declines in stem cell function can be reversed by a 24-hour fast, according to a new study from MIT. Biologists found fasting dramatically improves stem cells’ ability to regenerate, in both aged and young mice.
Explore how biologist John Calhoun's controversial mouse experiments sparked debates about overpopulation, urban life, and human society's future.
If you’ve ever been given a can of Diet Coke or Diet Pepsi and it tastes a little off, or way off, you probably just toss it out. Why does this happen and what can you do about it? Many diet soft d…
Researchers at the Department of Neurology of the University of Bern and University Hospital Bern identified how the brain triages emotions during dream sleep to consolidate the storage of positive emotions while dampening the consolidation of negative ones. The work expands the importance of sleep in mental health…
The tandem solar cell converts 32.5% of the incident solar radiation into electrical energy. This value is now officially certified and included in the NREL chart.
Our office chair, the air we breathe, the stars in the night sky: they are all made of atoms, which in turn are composed of electrons, protons and neutrons. Electrons are negatively charged; according to current knowledge, they have no expansion, but are point-like. The positively charged protons are different …
Actually no, the results will probably not surprise you.
A new study by MIT engineers shows how shaving can damage blades. Human hair, 50 times softer than steel, can chip away a razor’s edge, the engineers found.
Intestinal flora plays an important role in health – including mental health. Researchers from the University of Basel and the University Psychiatric Clinics Basel (UPK) have shown that probiotics can support the effect of antidepressants and help to alleviate depression.
