Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.

A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.

An AI-powered analysis of 25 years of satellite images yields the surprising finding that methane emissions in Turkmenistan, a former Soviet republic and major oil-producing region, actually increased in the years following the dissolution of the Soviet Union.

Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests those particles may be more harmful to health than particles exiting the tailpipe.

Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?

A new study finds that policies to reduce carbon dioxide (CO2) emissions from motor vehicles combined with investments in electric vehicles and public transportation would reduce air pollution and bring large benefits to children's health. They would also save money.

Scientists have found a new way to calculate the total carbon emissions consistent with the Paris climate targets of 1.5 degrees Celsius and 2 degrees Celsius of global warming.

For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'

A recent study showed that it is possible to discern the composition of a buried pipe by striking an accessible portion of it and monitoring the sound waves that reach the surface. This method could help water utility companies verify the location of lead water lines without having to break ground.

At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers have now succeeded in making new viscose -- from worn-out cotton sheets.

A type of nanoparticle called a metal organic framework (MOF) could be used to deliver vaccines and act as an adjuvant. Researchers find these particles provoke a strong immune response by activating the innate immune system through cell proteins called toll-like receptors.
