"This megamaser is unusual because it is located at a very large distance. That means we are observing it from a much earlier time in the universe." When you purchase through links on our site, we may ...

Laser weapons have become super portable. Defense and security company NUBURU's Lyocon subsidiary has adapted industrial laser technology to create an anti-drone laser weapon small and light enough to ...

Bubbles in a 3-million-year-old ice core have allowed researchers to measure gases in the atmosphere during the late Pliocene for the first time. This epoch, when global temperatures are thought to ...

The consensus among the world's scientists is that greenhouse gases — including carbon dioxide and methane — are driving climate change, resulting in droughts, storms, heat and rising sea levels. It ...

An ant that can turn carbon dioxide in the air into dolomite stone in its exoskeleton may hold clues to how humans can sequester greenhouse gases to avert climate disaster. Fungus-farming ants forage ...

The headlines lately have verged on science fiction. A few weeks ago, my colleague Simon Shuster reported that the Ukrainian military had unveiled a new anti-drone laser weapon called the Sunray. On ...

Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring ...

PCWorld explains how to create an affordable CO2 air quality monitor using a Raspberry Pi and MH-Z19C sensor for under $40. This DIY project helps monitor indoor air quality since high CO2 levels ...

China has begun commercial operation of a power generation system that uses carbon dioxide instead of steam, marking the first real-world deployment of the technology. On Dec. 20, a supercritical CO2 ...

When two people book the same flight, they can get wildly different carbon footprints from online calculators. Many carbon calculators leave out big chunks of climate impact or rely on oversimplified ...

The engine in your car, truck, or SUV can run on either copper, platinum, or iridium spark plugs. You probably heard the hype around iridium plugs and how they manage to deliver solid sparks while ...

A team of physicists from the University of Innsbruck and Harvard University has proposed a fundamentally new way to generate laser light: a laser without mirrors. Their study, published in Physical ...
