Red dwarfs are the most abundant stars in the Milky Way, making up 70% of all stars.

A yearlong study examining ethnic and racial diversity in forensic science has found that the varying disciplines, which frequently work closely with law enforcement, are also generally whiter than the U.S. population it serves.

Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and "antimatter"—particles that are matter counterparts but with opposite charge. But then, as space expanded, the universe cooled. Today's universe is full of galaxies and stars that are made of matter. Where did the antimatter go, and how did matter come to dominate the universe? This cosmic...

The brain is arguably one of the most complex structures in the known universe.

Higher high tides, supercharged by rising sea levels, could flood all or parts of an estimated $34 billion worth of real estate along the nation's coasts within just 30 years, a new report concludes.

For most of his career, David Hondula worked as a professor and environmental science researcher at Arizona State University studying the impact of the changing climate.

The remains of a female "vampire" have been unearthed by archaeologists at a cemetery in Europe, Polish researchers announced this week.

It is sometimes said that science is about truth, while engineering is about compromise.

Supplementing the feed of dairy cattle with enzymes from two fungi simultaneously has a positive effect on the animals' lactational performance, according to Penn State researchers, who studied the concept in an experiment with cows.

Shale oil, a type of crude oil similar to petroleum, is found between layers of organic-rich shale. It can be refined into petrol, diesel, and other products, making it a sought-after resource. The Qingshankou Formation in the Gulong Sag of the Songliao Basin in China is a large geological body of shale deposits formed at the bottom of an ancient lake. These deposits contain about 15.3 billion...

Recent advances in imaging technology have made it possible to visualize intracellular dynamics, which offers a better understanding of several key biological principles for accelerating therapeutic development. Fluorescent labeling is one such technique that is used to identify intracellular proteins, their dynamics, and dysfunction. Both internal as well as external probes with fluorescent dyes...

A Penn State-led team of interdisciplinary researchers has developed techniques to improve the efficiency of CRISPR-Cas9, the genome editing technique that earned the Nobel Prize in 2020. While CRISPR-Cas9 is faster, less expensive and more accurate than other gene-editing methods, according to project leader Xiaojun "Lance" Lian, associate professor of biomedical engineering and biology at Penn...

Just two weeks after announcing the development of a mouse embryo model, complete with beating hearts and the foundations for a brain and other organs, from mouse stem cells, researchers in the laboratory of Magdalena Zernicka-Goetz, Bren Professor of Biology and Biological Engineering, have published new findings about another mouse embryo model reaching similar developmental stages, but created...

Charging and discharging a battery cell transforms its electrode material into a "super" material.

Researchers have developed a thin lens with a continuously tunable focal length. The new lens could one day make visual fatigue from augmented and virtual reality (AR/VR) devices a thing of the past.

Researchers at the University of São Paulo (USP) and the State University of Campinas (UNICAMP) have conducted the most comprehensive genetic analysis ever of the American bullfrog (Aquarana catesbeiana) in Brazil, concluding that there are two populations of the species here, living on frog farms or invading local ecosystems. Bullfrogs are considered the world's main invasive amphibian.

Greece has ratified a complex deal for the return, over coming decades, of 161 striking ancient Greek artifacts from a U.S. billionaire's collection after Athens conceded it had no evidence they'd been illegally excavated and exported.

States are acting to decriminalize possession of most or all controlled substances, according to updated data released today by the Temple University Center for Public Health Law Research on LawAtlas.org that provide a high-level overview of legislation seeking to decriminalize personal drug possession.

Membrane technology is widely applied in water treatment for removing suspended particles, colloids, and organic pollutants from polluted water. As a typical representative of inorganic membrane with advantages such as high flux and chemical resistance, ceramic membrane has massive potential value in the treatment of surface water, municipal wastewater, and drinking water.

During the COVID-19 pandemic, Latinas left their jobs in large numbers as they were forced to shoulder an unequal share of household and child care responsibilities, and most haven't reentered the workforce despite an economic rebound, according to a report published today by the UCLA Latino Policy and Politics Institute.

Solid-aqueous interfaces are ubiquitous and essential in a diverse range of natural and man-made systems and processes, from mineral formation, rock weathering and metal corrosion, to the intricate functioning of biological membranes and ion channels.

Stable isotopes in precipitation are important indicators for studying changes in the Earth's water cycle and reconstructing the paleoclimate history. Previous studies have shown that the precipitation stable isotopes in Asia recorded in stalagmites and other sediments have prominent periodic change patterns on the 10,000-year scale (orbital scale) in geological periods, but in the scientific...

When the COVID-19 pandemic swept the globe, many people turned to online sources to find health information. That was also largely the case for racial and ethnic minority populations in the United States, and a new study from the University of Kansas found they faced many of the same challenges such as encountering misinformation online, but also unique factors such as harassment, hostility and...

A review paper by scientists at Zhejiang University summarized the development of continuum robots from the aspects of design, actuation, modeling and control. The new review paper, published on Jul. 26 in the journal Cyborg and Bionic Systems, provided an overview of the classic and advanced technologies of continuum robots, along with some prospects urgently to be solved.
