Electrically tunable nonlinear polaritonic metasurface for THG. Credit: Light: Science & Applications (2024). DOI: 10.1038/s41377-024-01517-y A recent study has unveiled a transformative nonlinear optical metasurface technology. This new technology, characterized by structures smaller than the wavelength of light, paves the way for significant advancements in next-generation communication technologies, including quantum light sources and medical diagnostic … Read more

Stepwise assembly of the 20S proteasome is mediated by multiple chaperone interactions. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52513-0 Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell’s recycling process for obsolete and misshapen proteins—known as proteasomes—are formed. “Proteasomes are absolutely essential for health,” said Jianhua Zhao, … Read more

Credit: CC0 Public Domain Earth will capture a miniature, “second moon” this week, according to NASA scientists. The new moon is actually a tiny asteroid dubbed 2024 PT5. It will start orbiting the planet in a horseshoe path and stick around for a little less than two months before escaping Earth’s gravitational pull and going … Read more

The Amazon River in Leticia, Colombia. The Amazon River has seen its levels in Colombia reduced by as much as 90 percent, a government agency said Thursday, as South America faces a severe and widespread drought. The river—the world’s biggest by volume and which also flows through parts of Brazil, Peru, Bolivia, Ecuador, Venezuela, Guyana, … Read more

Flow chart outlining the determination of flood generating mechanisms for each flood event. Mechanisms include: Snowmelt (Melt), rain‐on‐snow (ROS), short‐duration, high‐intensity rain with different soil antecedent moisture conditions (AMC): dry (SR− ), normal (SR), wet (SR+), and long‐duration, lower‐intensity rain classified by AMC: dry (LR− ), normal (LR), and wet (LR+).

Developing cumulus clouds. Credit: Yang Gao As global warming continues, convective weather events are becoming more frequent. The early stage of these storms, known as convective initiation (CI), can be monitored using geostationary satellites. However, detecting CI accurately remains a challenge. The current detection methods still have a high rate of false alarms and missed … Read more
