Another first: Webb identifies frozen water in young star system

Another first: Webb identifies frozen water in young star system

Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system.

Photonic chip design offers simpler solution for one-way light flow in optical circuits

Photonic chip design offers simpler solution for one-way light flow in optical circuits

To improve photonic and electronic circuitry used in semiconductor chips and fiber optic systems, researchers at the McKelvey School of Engineering at Washington University in St. Louis tinkered with the rules of physics that govern the movement of light over time and space. They have introduced a new way to manipulate light transmission, opening possibilities for advanced optical devices.

Shifting pollution abroad may help democratic nations appear more environmentally friendly than non-democratic countries

Shifting pollution abroad may help democratic nations appear more environmentally friendly than non-democratic countries

Democratic countries tend to be rated "greener," or more environmentally friendly, compared to other countries—but this may be because they more often outsource the environmental impacts of their consumption to other nations, according to a study published in PLOS Climate by Thomas Bernauer and Ella Henninger from ETH Zurich, Switzerland and Tobias Böhmelt from the University of Essex.

Durable catalyst boosts efficiency of high-temperature CO₂ conversion

Durable catalyst boosts efficiency of high-temperature CO₂ conversion

We've all heard that carbon dioxide (CO2) emissions need urgent solutions, but what if we could turn this greenhouse gas into useful chemicals or fuels? Electrochemical CO2 conversion—the process of transforming carbon dioxide into valuable products—is a promising path toward greener energy and reducing emissions. The catch? Existing methods either don't last long or consume too much energy, limiting their real-world use.

Ancient climate patterns help refine predictions for South Asian monsoon changes

Ancient climate patterns help refine predictions for South Asian monsoon changes

The South Asian Summer Monsoon (SASM) is the world's most significant monsoon system, providing approximately 80% of the region's annual rainfall—influencing agriculture, water security, and the livelihoods of more than a billion people across the Indian Peninsula, the western Indochina Peninsula, and the southern Qinghai-Tibet Plateau.
