Sodium’s high-pressure transformation can tell us about the interiors of stars, planets
2023-12-29
Travel deep enough below Earth’s surface or inside the center of the Sun, and matter changes on an atomic level.
The mounting pressure within stars and planets can cause metals to become nonconducting insulators. Sodium has been shown to transform from a shiny, gray-colored metal into a transparent, glass-like insulator when squeezed hard enough.
Now, a University at Buffalo-led study has revealed the chemical bonding behind this particular high-pressure phenomenon.
While it’s been theorized that high pressure essentially squeezes sodium’s electrons out into the spaces between atoms, researchers’ quantum chemical ...
Endocrine Society applauds Ohio governor veto of state ban on gender-affirming care for minors
2023-12-29
WASHINGTON—The Endocrine Society, the world’s oldest and largest professional medical society devoted to the study and treatment of hormone-related conditions, applauds Governor Mike Dewine’s veto of a proposed Ohio law that would have banned gender-affirming care for minors. The bill he vetoed contradicts mainstream medical practice and scientific evidence and would have taken medical decision-making out of the hands of families and their physicians and instead relied upon government officials.

Molecules exhibit non-reciprocal interactions without external forces, new study finds
2023-12-29
Researchers from the University of Maine and Penn State discovered that molecules experience non-reciprocal interactions without external forces.
Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are attracted to each other or are repelled by each other. In our everyday experience, however, interactions don’t seem to follow this reciprocal law. For example, a predator is attracted to prey, but the prey tends to flee from the predator. Such non-reciprocal interactions are essential for complex behavior associated with living organisms. ...

In coastal communities, sea level rise may leave some isolated
2023-12-29
COLUMBUS, Ohio – Amid the threat of dramatic sea level rise, coastal communities face unprecedented dangers, but a new study reveals that as flooding intensifies, disadvantaged populations will be the ones to experience some of the most severe burdens of climate change.
While accelerating sea level rise will result in widespread intermittent flooding and long-term inundation in many coastal communities, the paper, recently published in Nature Communications, showed that when these levels increase above 4 feet, minority populations will be disproportionately at risk of isolation.
Rising sea levels could lead to isolation by disrupting transportation ...

New perspectives on treating gallbladder inflammation
2023-12-28
Ischaemic cholecystitis is a form of gallbladder inflammation that occurs without gallstones or another form of external compression. It is caused by poor perfusion to the gallbladder tissue.
This new research is important because it helps to better understand the cause of ischaemic cholecystitis and to develop more effective treatments for this condition.
A team of researchers from the University of California, San Francisco, conducted a study investigating the cause of ischaemic cholecystitis. They found that the gallbladder is particularly susceptible to ischaemia ...
Brain health after COVID-19, pneumonia, heart attack, or critical illness
2023-12-28
About The Study: The findings of this study including 345 participants suggest that post–COVID-19 brain health was impaired but, overall, no more than the brain health of patients from 3 non–COVID-19 cohorts of comparable disease severity. Long-term associations with brain health might not be specific to COVID-19 but associated with overall illness severity and hospitalization. This information is important for putting understandable concerns about brain health after COVID-19 into perspective.

Future labor losses due to heat stress in China under climate change scenarios
2023-12-28
Climate change is the biggest global health threat in the 21st century, and the rising temperatures have undermined the health and safety of the working population, as well as caused labor losses, which are closely tied to social-economic development. Although the future temperatures increase in China has been forecasted by state-of-the-art climate change projections, to what extent the influence on labor has not been well studied. In a paper published in Science Bulletin, a Chinese research team presents evidence of future labor losses due to heat stress in China under climate change scenarios. This study was led by Cunrui Huang, a professor at the Vanke School of Public ...
Acellular players in the high cryosphere: diversity, function and activity of the global supraglacial DNA viruses
2023-12-28
Supraglacial environments mainly consist of four main types of habitats for microbes and viruses, including snow, ice, meltwater, and cryoconites (the granular sediment on glacier surfaces). The paper revealed that there were more than 10,000 viral species in global supraglacial environments. This is a 15-fold expansion of DNA viral genomic inventory ever known. These viruses mainly belong to bacteriophages, viruses infecting bacteria. Liu et al., also found the viral communities showed a clear regional and habitat distribution pattern, with polar glacier samples separated from mountain ...
A carbon-lite atmosphere could be a sign of water and life on other terrestrial planets, MIT study finds.
2023-12-28
Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers’ best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the presence, of a chemical feature in their atmospheres.
The researchers propose that if a terrestrial planet has substantially less carbon dioxide in its atmosphere compared to other planets in the same system, it could be a sign of liquid water — and possibly life — on that planet’s surface.
What’s more, this new signature is within the sights of NASA’s James Webb Space Telescope (JWST). While scientists have proposed ...
