Standard Temperature and Pressure

Want to keep your eye on the sky in 2025? Here's a look at the best space launches you can watch from the comfort of home.

Water fluoridation is still up for debate in the US. According to experts, here are the facts.

Blue Ghost and New Glenn started off the year right. Many more launches are on the way, and many can be watched online.

The benefits outweigh the risks

Nuclear-powered rockets could one day enable faster space travel.

An exotic molecule stabilized by intense pressure found in the icy depths of Neptune and Uranus could help explain a long-standing mystery.

Dimethyl-ether is a single molecule that can be produced from a wide range of renewable feedstocks. It can be blended with LPG and used in existing applications. It is chemically similar to propane and butane, and is a gas at room temperature and pressure. Like LPG it is easily transported as a liquid in pressurized

"Small nuclear reactors may be coming to Texas, boosted by interest from Gov. Abbott" was first published by The Texas Tribune, a nonprofit, nonpartisan media organization that informs Texans — and engages with them — about public policy, politics, government and statewide issues.Sign up for The Bri...

Contemporary American artist Richard Serra, known for his massive yet minimalist steel sculptures, died Tuesday at age 85, U.S. media reported.His strikingly large pieces are installed all over the world, from Paris museums to the Qatari desert, and have sometimes sparked controversy over their impo...

The retro "drinking bird" is making a surprising comeback — as the inspiration for a clean-energy generator that could one day power your watch and phone.

Refractory organic pollutants, including phenols, perfluorinated compounds, and antibiotics, are abundant in various industrial wastewater streams such as chemical, pharmaceutical, coking, and dyeing sectors, as well as municipal and domestic sources. These pollutants pose significant threats to ecological well-being and human health.

Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique developed by a team of international scientists could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing…

Following a flurry of replication attempts, the claim that LK-99 perfectly conducts electricity at room temperature and pressure is looking unlikely to hold up

This is what a historic wave of general-purpose technologies looks like

Two Trailblazing Companies Team Up to Create World's First Fire Extinguisher Solution for Global Crisis

Flexible spheres of the biomolecule chitosan, made from shrimp waste, can be used for catalysts that generate hydrogen gas from borohydride salts. In a paper in Green Chemistry, a research team at the University of Amsterdam (UvA) shows how the spheres can "breathe out" hydrogen bubbles without breaking. This is an important step towards practical and safe hydrogen storage and release units.

UChicago researchers hope "islands" of exciton condensation could pave the way for new discoveries. Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Meanwhile, just outside their window, trees are absorbing sunlight and converting it

Researchers have demonstrated a new material for single-molecule electronic switches, which can effectively vary current at the nanoscale in response to external stimuli. The material for this molecular switch has a unique structure created by locking a linear molecular backbone into a ladder-type structure. A new study finds that the ladder-type molecular structure greatly enhances the stability of the material,…

There are benefits of studying certain biological processes under microgravity, but whether those advantages outweigh the costs of getting experiments off Earth remains to be seen.

People in Washington, D.C., and Virginia were rattled Sunday by an explosive sound later confirmed to be a sonic boom caused by jets flying overhead.
