Researchers found the rate of virus exposure among Black and Hispanic women to be five times higher than among White and Asian women.

A way of shrinking the devices used in quantum sensing systems has now been developed.

From 1995 to 2017, work that was awarded a Nobel Prize in Medicine, Physics, or Chemistry clustered in just a few scientific disciplines.

Alarming results from a 2019 survey of well-known archaeological site Ageröd reveal drastic bone and organic matter deterioration since the site's initial excavations in the 1940s, suggesting action is needed to preserve findings from Ageröd and similar sites, according to a new study.

Geological evidence suggests the known dinosaur groups diverged early on, supporting the traditional dinosaur family tree.

How does water leave a sponge? In a new study, scientists answer this question in detail for a porous, crystalline material made from metal and organic building blocks -- specifically, cobalt(II) sulfate heptahydrate, 5-aminoisophthalic acid and 4,4'-bipyridine. Using advanced techniques, researchers studied how this crystalline sponge changed shape as it went from a hydrated state to a...

A new study confirms that while the eastern and western butterflies fly differently, they are genetically the same.

Air conditioning and other space cooling methods account for about 10% of all electricity consumption in the U.S., according to the U.S. Energy Information Administration. Now, researchers have developed a material that cools the wearer without using any electricity. The fabric transfers heat, allows moisture to evaporate from the skin and repels water.

Researchers have solved a 20-year-old problem in quantum information theory on how to calculate entanglement cost -- a way to measure entanglement -- in a manner that's efficiently computable, useful, and broadly applicable in several quantum research areas.

In a pilot study of people living with HIV or high levels of cholesterol, researchers found that a six-week course of a cholesterol-lowering medication improved the function of the coronary arteries that provide oxygen to the heart.

A typical recycling process converts large quantities of items made of a single material into more of the same. However, this approach isn't feasible for old electronic devices, or ''e-waste,'' because they contain small amounts of many different materials that cannot be readily separated. Now researchers report a selective, small-scale microrecycling strategy, which they use to convert old...

Extensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts of stored magnetic energy due to changes in the magnetic field of the sun's outer atmosphere - something that until now has eluded scientists' direct measurement. Researchers...

An aurora sightseeing tour leader in Alaska, was lucky enough to photograph a 'eruption' of brilliant pink light in the night skies one night in February.

Research may provide new insights into wound healing, scarring and how cancer spreads.

Even short, single antibiotic courses given to young animals can predispose them to inflammatory bowel disease (IBD) when they are older, according to new researchers. The study provides further evidence supporting the idea that the use of antibiotics in children under 1 year old disrupts the intestinal microbiota - the trillions of beneficial microorganisms that live in and on our bodies - that...

A study details the changes that occurred in the Arctic in September of 2018, a year when nearly 10 million kilometers of sea ice were lost throughout the summer. Its findings give an overview of how sea ice has receded over the 40 years of the satellite era and show how the summer's extensive decline is linked to global atmospheric processes as far south as the tropics.

Steady progress in reducing the rates of premature cardiac death in the US began slowing in 2011, largely due to rising rates of out-of-hospital premature cardiac deaths, especially among younger adults. County-level disparities in premature cardiac death rates across the US have widened over the past two decades.

Research gives possible answers to increase pollinator populations on farms.

Per- and polyfluoroalkyl substances (PFAS), found in many household products and food packages, have raised concerns because of their persistence and possible toxicity to people and wildlife. Because the compounds don't break down naturally, they have become environmental contaminants. Now, researchers have studied the transport of 29 PFAS into and out of the Arctic Ocean, detecting a newer...

The largest and most complex CRISPR system has been visualized by researchers in a new study. The system may have potential applications in biomedicine and biotechnology, the researchers believe.

Once found in bottles, food containers, cash register receipts and electronics, bisphenol A (BPA) has been phased out of many products because of health concerns and government regulations. As a result, the production and use of BPA analogs, which are unregulated and poorly understood, have increased. Now, by analyzing urine samples and wastewater, researchers report how human exposure to...

Mussels secrete sticky plaques that help them attach to wet surfaces, such as rocks on the beach. These adhesive structures are rich in iron, which is thought to help make the attachments strong yet flexible. Now, researchers have shown that mussels form weaker attachments in iron-deficient seawater, revealing a possible consequence of altered iron bioavailability in oceans.

Grassroots knowledge from indigenous people can help to map and monitor ecological changes and improve scientific studies, according to new research. The study shows the importance of indigenous and local knowledge for monitoring ecosystem changes and managing ecosystems. The team collected more than 300 indicators developed by indigenous people to monitor ecosystem change, and most revealed...

Nanoengineers have developed a new method to fabricate perovskites as single-crystal thin films, which are more efficient for use in solar cells and optical devices than the current state-of-the-art polycrystalline forms of the material. Their fabrication method -- which uses standard semiconductor fabrication processes -- results in flexible single-crystal perovskite films with controlled area,...
