As researchers investigate reasons for America's persistent gender wage gap, one possible explanation that has emerged in roughly the last decade is that women may be less competitive than men, and are therefore passed over for higher-ranking roles with larger salaries.
Scientists may have made a giant leap in fighting the biggest threat to human health by using supercomputing to keep pace with the impressive ability of diseases to evolve. A new study by an international team, co-led by Dr Gerhard Koenig from the University of Portsmouth, tackled the problem of antibiotic resistance by redesigning existing antibiotics to overcome bacterial resistance mechanisms.

An NUS study revealed strong positive correlation between domestic electricity use and newly reported cases in Singapore at the height of the pandemic in 2020. This can be useful for policymakers to assess people’s willingness in embracing risk-reduction behaviours.
Sustainability is a 21st century buzzword, but a new interdisciplinary study shows that some communities have been conducting sustainable practices for at least a thousand years. Published in the Proceedings of the National Academy of Sciences and coauthored by University of Oregon archaeologist Scott Fitzpatrick, the study integrates data from archaeology, history and paleoecology to gain new insight into human-environmental interactions in the deep past. Focused on tropical island archipelagoes including Palau in Micronesia, the interdisciplinary data suggest that human-driven environmental change created feedback loops that prompted new approaches to resource management. The data from Palau point to human impacts on marine ecology beginning about 3,000 years ago, impacts that affected fish populations and therefore one of ancient Palau’s most important food sources.
Glaciologists at the University of California, Irvine and NASA’s Jet Propulsion Laboratory have examined the dynamics underlying the calving of the Delaware-sized iceberg A68 from Antarctica’s Larsen C ice shelf in July 2017, finding the likely cause to be a thinning of ice melange, a slushy concoction of windblown snow, iceberg debris and frozen seawater that normally works to heal rifts.

A phase II, randomized clinical trial found that the optimal period for intensive rehabilitation of arm and hand use after a stroke should begin 60 to 90 days after the event. The study, conducted by Georgetown University and MedStar National Rehabilitation Network (NRH) researchers, published September 20, 2021, in PNAS.
Researchers measured the potassium isotope compositions of Martian meteorites in order to estimate the presence, distribution and abundance of volatile elements and compounds, including water, on Mars, finding that Mars has lost more potassium than Earth but retained more potassium than the Moon or the asteroid 4-Vesta; the results suggest that rocky planets with larger mass retain more volatile elements during planetary formation and that Mars and Mars-sized exoplanets fall below a size threshold necessary to retain enough water to enable habitability and plate tectonics.
A study led by UT Southwestern dermatologists suggests that a common inflammatory skin condition may stem from poorly regulated sex hormones. The finding, published this week in PNAS, could offer an unexpected new target to fight this condition.

Even with federal provisions aimed at protecting workers, instances of sick people being unable to take time off tripled during the pandemic and fewer than half of workers were aware that emergency COVID-19 sick leave was available, new research from Cornell University professor Nicholas Ziebarth has found.
In an effort to understand how these states influence the brain’s decision-making processes, scientists at the Icahn School of Medicine at Mount Sinai analyzed the data from a previous pre-clinical study. They found that two of the brain’s decision-making centers contain neurons that may exclusively monitor the body’s internal dynamics. Furthermore, a heightened state of arousal appeared to rewire one of the centers by turning some decision-making neurons into internal state monitors.
From small committees to national elections, group decision-making can be complicated — and it may not always settle on the best choice.

A groundbreaking study from U-M reveals several drug contenders already in use for other purposes—including one dietary supplement—that have been shown to block or reduce SARS-CoV2 infection in cells.
People born blind have never seen that bananas are yellow but Johns Hopkins University researchers find that like any sighted person, they understand two bananas are likely to be the same color and why. Questioning the belief that dates back to philosopher John Locke that people born blind could never truly understand color, the team of cognitive neuroscientists demonstrated that congenitally blind and sighted individuals actually understand it quite similarly.

The technology has been patented and is receiving interest from industry.
Microbes have played a key role in our food and drinks – from cheese to beer – for millennia but their impact on our nutrition may soon become even more important.
An untapped trove of desirable drug-like molecules is hidden in the genomes of Streptomyces bacteria — the same bacteria responsible for the first bacterial antibiotics to treat tuberculosis back in the 1940s. Isolating them, however, has proved challenging. Now, biologists at Washington University in St. Louis are using comparative metabologenomics to try to uncover what may be “silencing” Streptomyces and preventing it from producing desirable compounds encoded by its genes.
