Hundreds of firefighters endured triple-digit temperatures Thursday battling against a wildfire along a major highway, as the western United States bakes under a fearsome heat dome.

YouTube was more likely to recommend videos about election fraud to users who were already skeptical about the legitimacy of the 2020 U.S. presidential election, shows a new study examining the impact of the site's algorithms.

A Duke research study is preparing to blast off to the Moon with NASA on Artemis I.

Cities can have many benefits when designed well, including reducing carbon imprints. Another way cities can improve their environmental impact is by using "low-impact development" with regard to water management. It is also called "green stormwater infrastructure."

People typically spend 90% of their lives inside, at home, at work, or in transport. Within these enclosed spaces, occupants are exposed to a multitude of chemicals from various sources, including outdoor pollutants penetrating indoors, gaseous emissions from building materials and furnishings, and products of our own activities such as cooking and cleaning. In addition, we are ourselves potent mobile emission sources of chemicals that enter the indoor air from our breath and skin.

Composite particles with submicron sizes can be produced by irradiating a suspension of nanoparticles with a laser beam. Violent physical and chemical processes take place during irradiation, many of which have been poorly understood to date. Recently completed experiments, carried out at the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, have shed new light on some of these puzzles.

This study is led by Dr. Yong Tao (Institute of Microbiology, Chinese Academy of Sciences), Dr. Weifeng Liu (Institute of Microbiology, Chinese Academy of Sciences) and Dr. Bo Liu (Microcyto Co. Ltd.,). Fatty acids are promising alternative feedstocks to glucose and can be easily obtained from various sources, including waste oil, crude oil, and oil by‐products. In recent years, Prof. Yong Tao 's group has been committed to develop economically and ecologically competitive bioproduction processes using alternative biomass. Читать дальше...

Shale oil exploration has rapidly expanded since the beginning of the 21st century, particularly in North America. Since 2010, the production of marine shale oil has increased at an average rate of more than 25% annually, making the US the global leader in production with total recoverable resources pegged at approximately 20.7 billion tons. Developing shale oil resources has significant potential to shape energy security and geopolitics. In addition to marine shale oil, countries have also begun utilizing lacustrine basins for oil production.

The wellness center at Utah's Westlake High School is a port in the storm of adolescence. With comfortable couches, soft lighting, nature sounds, healthy snacks and an array of sensory activities like Buddha Boards and puzzles, the wellness center offers overwhelmed students a place to relax and refocus, practice healthy coping mechanisms or talk with a counselor.

Since the outbreak of COVID-19, the importance of wearing masks and disinfection of items has become paramount. As a result, there is now a greater need for effective, potent, and simple-to-apply disinfectants. Foam-type disinfectants are a leading candidate in this regard since they do not drip, keep the disinfected area visible, and are less likely to reach the user's eyes.

Forests are engaged in a delicate, deadly dance with climate change, sucking carbon dioxide out of the air with billions of leafy straws and hosting abundant biodiversity, as long as climate change, with its droughts, wildfires and ecosystem shifts, doesn't kill them first.

A Policy Forum article published today in Science calls for a new approach to regulating genetically engineered (GE) crops, arguing that current approaches for triggering safety testing vary dramatically among countries and generally lack scientific merit—particularly as advances in crop breeding have blurred the lines between conventional breeding and genetic engineering.

An insulin-suppressing protein may be the fountain of youth for ants and provides clues about aging in other species, according to a study led by New York University researchers.

Bacteria regularly develop and deploy new antibiotics in a never-ending arms race to kill other bacterial species that compete for mutual resources. Humans have capitalized on that evolutionarily honed capability by administering antibiotics to strike at harmful bacteria that invade and infect their bodies.

New research shows that lemurs and their food trees are tightly linked in ecological networks, and that the extinction of lemurs will have cascading effects on ecosystem functions.

Harmful algal blooms (HABs) are phytoplankton colonies that may harm aquatic ecosystem and human health. The fish die-offs, shellfish closures and reluctance among consumers to eat seafood often caused by these blooms costs the U.S. an average of $4.6 billion annually.

Astronomers from the University of Exeter have led the effort to capture the first-ever direct image of an exoplanet using the pioneering James Webb Space Telescope.

Greenhouse gas concentrations, global sea levels and ocean heat content reached record highs in 2021, according to the 32nd annual State of the Climate report.

If NASA is to boldly go where no man has gone before, the federal agency might have Tampa to thank for it.

Don Fullerton is the Gutgsell Professor of Finance at the Gies College of Business at the University of Illinois Urbana-Champaign and a senior scholar at the Institute of Government and Public Affairs. Fullerton, an expert in energy and environmental policy, spoke with News Bureau business and law editor Phil Ciciora about the environmental impact of the Inflation Reduction Act of 2022.

The synthesis and study of radioactive compounds are naturally difficult due to the extreme toxicity of the materials involved, but also because of the cost and scarcity of research isotopes.

Sick of sweltering summer heat? Well, you are in luck, because fall starts Thursday, at least according to meteorologists.

Tens of tons of extraterrestrial solid material collide with Earth daily. Most of this material is small enough that it burns up in the atmosphere, but some fragments are large enough to cause quite a predicament. In 2013, a 20-meter-diameter body exploded over Chelyabinsk, seriously injuring more than 1,500 people.

A collaborative team of researchers in the Texas A&M College of Agriculture and Life Sciences Department of Horticultural Sciences and the Department of Biology has developed a unique system of identifying host plants of crapemyrtle bark scale, an insect that destroys plants by feeding on their sap.

There is no "I" in team … but there is a "me."
