More and more papers are coming out about the upcoming Habitable Worlds Observatory (HWO). As the telescope moves from theory ...

What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool ...

NASA researchers identify optimal infrared wavelength for detecting carbon dioxide and methane on exoplanets, guiding the Habitable Worlds Observatory’s design and sensor specifications.

There is widespread recognition that efforts to meet global climate targets cannot be met by curbing new carbon dioxide emissions alone and will also require removing carbon from the atmosphere at ...

The sensor lineup includes smart plugs, air quality monitors, and motion detectors, and automatically connects to Sidewalk without a hub or Wi-Fi. I’m PCMag’s senior writer covering smart home and ...

This all-purpose presence sensor is a master at monitoring indoor activity and linking it to smart home features you already use. Tyler has worked on, lived with and tested all types of smart home and ...

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 ...

Patients are being warned to stop using some glucose monitors made by Abbott Diabetes Care after the company found malfunctioning sensors may be linked to hundreds of adverse events and several deaths ...

A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of carbon ...

Surging emissions from wildfires may have been behind the increase, which was the largest since modern measurements began more than half a century ago. By Raymond Zhong and Sachi Kitajima Mulkey The ...

GENEVA (AP) — Heat-trapping carbon dioxide levels in the atmosphere jumped by the highest amount on record last year, soaring to a level not seen in human civilization and "turbo-charging" the Earth's ...
