How does low-impact development help manage stormwater?

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."

Rethinking indoor air chemistry

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...

Laser melting: Fewer unknowns in the laser nanosynthesis of composites

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...

Fatty acid feedstocks enable a highly efficient glyoxylate‐TCA cycle for high‐yield production of β‐alanine

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...

New study suggests lacustrine shale reserves can bolster China's energy independence

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...

School wellness centers: An innovative response to student stress and suicide

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.

Improving foam stability in disinfectants with high ethanol concentrations

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.

Global analysis identifies at-risk forests

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.

Researchers propose new framework for regulating engineered crops

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.

Experiment IDs influence of antibiotics, isolation on host bacteria

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.

How will the Inflation Reduction Act affect US environmental policy?

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.
