Electrode technology achieves 86% efficiency for converting CO₂ into plastic precursors

Japan's space agency, JAXA, has been knocking it out of the park with small-body exploration missions for decades. They had historic successes with both Hayabusa and Hayabusa2, and they are going to visit the Martian moons soon with the Martian Moons eXploration (MMX) mission. But after that, they are aiming for something much more pristine and arguably more difficult—a comet. The Next Generation Small-Body Return (NGSR) was recently described in a paper presented at the Lunar and Planetary Scie

A recent study by Dr. John Moretti of the University of Texas and local caver John Young uncovered the remains of Ice Age megafauna, revealing an entirely new ecosystem that once thrived on the Edwards Plateau. Among the finds were a genus of giant tortoise (Hesperotestudo) and a large armadillo-like pampathere (Holmesina septentrionalis). The work is published in the journal Quaternary Research.

On August 19, 2022, solar astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui caught the fading remnants of a C-class solar flare. Their observations showed something unusual: very strong spectral fingerprints of calcium II H and hydrogen-epsilon lines.

For decades, astronomers were only able to study the universe's very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the most compelling evidence to date for these ancient "Population III" stars, finding them clustered around a small companion object that formed just 400 million years after the Big Bang.
