Team designs nitride-reinforced NbMoTaWHfN refractory high-entropy alloy
A new generation of refractory alloys with excellent high-temperature performance is urgently demanded for aero-engines, gas turbines, and nuclear power plants. As the service temperature of their hot-ends is reaching 1800 °C or even higher, traditi.....»»
Colorado has a new plan to reduce greenhouse gases. Critics say it fails those most impacted by air pollution
Colorado's air regulators have approved a new rule that will require the state's 18 largest manufacturers to reduce their greenhouse gas emissions, but the plan is receiving pointed criticism from environmental advocates who say loopholes will allow.....»»
Gases from Philippine volcano sicken dozens of children, prompting school closures in nearby towns
Smog containing gases from a restive Philippine volcano sickened dozens of students and prompted 25 towns and cities to shut their schools on Friday as a health precaution, officials said......»»
Researchers reveal origins of zirconium nitride"s superior performance
A group of researchers have unraveled the mysteries behind a recently identified material—zirconium nitride (ZrN)—that helps power clean energy reactions. Their proposed framework will help future designs for transition metal nitrides, paving a p.....»»
Research finds ponds release more greenhouse gas than they store
Though human-made ponds both sequester and release greenhouse gases, when added up, they may be net emitters, according to two related studies by Cornell researchers......»»

Diesel exhaust gases found to harm insects: Animal ecologists study the effects on bumblebees for the first time
The decline of insects threatens many ecosystems worldwide. While the effects of pesticides are well researched, there has been a lack of knowledge about the effects of other anthropogenic pollutants. Animal ecologists at the University of Bayreuth h.....»»
NASA"s new greenhouse gas detector moves closer to launch
A state-of-the-art imaging spectrometer, which will measure the greenhouse gases methane and carbon dioxide from space, moved closer to launch this month after being delivered to a clean room at Planet Labs PBC (Planet) in San Francisco......»»
Novel device combines nanopores with electronic signals for disease detection
In living organisms, cells have a very high capacity to process and communicate information by moving molecules or ions through tiny channels that span the cell membrane. UC Santa Cruz Professor of Electrical and Computer Engineering Marco Rolandi's.....»»
International report confirms record-high greenhouse gases, global sea levels in 2022
Greenhouse gas concentrations, global sea level and ocean heat content reached record highs in 2022, according to the 33rd annual State of the Climate report......»»
Researchers reversely trap isolated atoms in high oxidation to accelerate oxygen evolution reaction kinetics
Single-atom catalysts (SACs), representing the ultimate high atom utilization efficiency and specific activity, have arguably become the most active new frontier in heterogeneous catalysis. The technology of atom trapping based on support effects is.....»»
Zimbabwe"s climate action plan: A win for the environment, health and energy
The dumping of billions of tons of carbon dioxide and other greenhouse gases into the atmosphere yearly is already having a devastating impact around the world. This includes widespread flooding and droughts, raging wildfires, heat waves and record t.....»»
Study quantifies link between greenhouse gases, polar bear survival
Polar bears have long symbolized the dangers posed by climate change, as rising temperatures melt away the Arctic sea ice they depend upon for survival......»»
Idaho"s Silver Valley is still at risk 50 years after mine fire caused largest lead-poisoning case in US history
On Sept. 3, 1973, a fire swept through the baghouse of the Bunker Hill mine in Idaho's Silver Valley. The building was designed to filter pollutants produced by smelting, the melting of rocks that separates metal from its ore. The gases produced in t.....»»
Greenhouse gases are changing air flow over the Pacific Ocean, raising Australia"s risks of extreme weather
