A new antimicrobial suture material that glows in medical imaging could be a promising alternative for mesh implants and internal stitches.

In a study published in Combustion and Flame, researchers investigated the impact of non-thermal reaction chemistry on the propagation of combustion fronts for a H2-CH4 fuel mixture burning in air within a bounded domain, representing an idealized engine cylinder.

The construction of the Fred Young Submillimeter Telescope (FYST) being developed by CCAT Observatory Inc., an international consortium of universities led by Cornell, is drawing to a close.

A team of researchers from the National Library of Medicine (NLM) and collaborating academic research institutions have developed a computational pipeline to identify and better understand viroids and viroid-like covalently closed circular RNAs (cccRNAs, also referred to simply as circular RNAs). This is a type of single-stranded RNA, which unlike linear RNA, forms a covalently closed, continuous...

Postdocs—the Ph.D.s who do much of the labor of science—are notoriously underpaid. But the problem has intensified over the past year as postdocs struggle to get by amid soaring inflation and professors report problems recruiting Ph.D. graduates to fill positions. Several institutions and states have recently implemented policies to increase their pay. But these...

Mars, the fourth planet from the sun, fascinates people in many ways. For atmospheric researchers it is an interesting subject as Mars is the most Earth-like planet of our solar system. Since 1976, probes landed on Mars have collected information on its dynamic weather phenomena.

In a new study, scientists with the University of Florida have found that a combination of silver nanoparticles and antibiotics is effective against antibiotic-resistant bacteria.

Peritoneal cancer is difficult to treat and has a poor survival prognosis. But a new and effective nanomedicine delivery system is offering some hope.

In medieval Europe, before the rise of oil paintings, fresco was a popular religious painting technique. Many artworks across Europe, hundreds of years old, utilize this method and constitute an important part of cultural heritage. Michelangelo's famous Sistine Chapel ceiling and Fra Angelo's Annunciation in Italy are perhaps two of the most well-known examples of frescoes. But how exactly does...

A research group of the Department of Electrical and Electronic Information Engineering at Toyohashi University of Technology—consisting of Hirotada Gamo, a doctoral course student; Kazuhiro Hikima, assistant professor; and Atsunori Matsuda, professor—has elucidated the decomposition behavior of electrolytes in the cathode composites of all-solid-state lithium-sulfur batteries (ASSLSB).

Global warming is an increasingly worrying problem. Although the greenhouse effect is a necessary process to maintain living conditions on Earth, our current societies are increasing the emission of greenhouse gases into the atmosphere and increasing its temperature by retaining more heat than necessary. Nature is trying to counteract this situation: plants are able to capture energy from sunlight...

A study led by the Institute of Environmental Assessment and Water Research (IDAEA) and the Mediterranean Institute for Advanced Studies (IMEDEA CSIC-UIB), both belonging to the Spanish National Research Council (CSIC), has shown that injecting billions of tons of atmospheric CO2 (carbon dioxide) underground has a low risk of leakage back to the surface.

Scientists say the bright green comet will be visible in the night sky for almost a month.

Cyanobacteria are single-celled organisms that derive energy from light, using photosynthesis to convert atmospheric carbon dioxide (CO2) and liquid water (H2O) into breathable oxygen and the carbon-based molecules like proteins that make up their cells. Cyanobacteria were the first organisms to perform photosynthesis in the history of Earth, and were responsible for flooding the early Earth with...

Nearly all the chemical energy available to Earth's lifeforms can be traced back to the sun. This is because light-harvesting (LH) supramolecules (two or more molecules held together by intermolecular forces) enable plants and some types of bacteria (typically at the base of the food chain) to leverage sunlight for driving photosynthesis. For these supramolecules to be effective, they need to have...

Soil can store carbon. Therefore, there is also an increasing focus on soil organic carbon content and how to either increase or maintain it. This is because soil can also lose carbon in the form of climate gases from microbial decomposition, in which case soil suddenly contributes to climate change rather than mitigating it. But to maintain or even increase the amount of carbon, farmers need to...

Environmentalists say the Brazilian navy's plan to abandon a massive aircraft carrier is a disaster for marine life.

Almost all of Africa's maize crop is at risk from the devastating fall armyworm pest (Spodoptera frugiperda) according to new research published in the journal Frontiers in Insect Science.

For thousands of years, crops have been shaped by domestication processes. Farmers cross-breed and select new varieties, adapted to constantly changing environments. Although efficient, this process is time consuming. Moreover, the desired trait must be present somewhere within the diversity of the species to be improved.

Many hospitality organizations see the benefits of engaging in corporate social responsibility (CSR), which can take many forms. Researchers at Surrey aimed to investigate the impact of hiring individuals experiencing houselessness on customers' behavioral intentions, attitudes toward an organization, and perceptions of CSR actions.

Cornell University researchers have found that white-tailed deer—the most abundant large mammal in North America—are harboring SARS-CoV-2 variants that were once widely circulated, but no longer found in humans.

At a time when climate change is making many areas of the planet hotter and drier, it's sobering to think that deserts are relatively new biomes that have grown considerably over the past 30 million years. Widespread arid regions, like the deserts that today cover much of western North America, began to emerge only within the past 5 to 7 million years.
