As NASA's Artemis II mission completed its lunar flyby, the astronauts sent back a stunning image of the colorful Earth setting behind the moon. This breathtaking photo, called Earthset, draws inevitable comparisons with the original Earthrise photo from the Apollo 8 flight in 1968. [...]
Rhodium is one of the most powerful catalytic metals known to chemistry. Small amounts of it can drive reactions that produce millions of tons of useful chemicals every year. But getting rhodium to work well—quickly, selectively, and without degrading—depends heavily on the ligands surrounding it. [...]
Spiders are among Earth's most resourceful predators, nabbing prey by any means necessary. Orb weavers spin webs for capture. Wolf spiders ambush on the ground at night. Almost all spiders use venom when they hunt. [...]
Between 280 and 200 million years ago, a group of animals evolved which would eventually give rise to mammals, including humans: the therapsids. They were first described more than 150 years ago, based on fossils from South Africa. Since then, many more fossils have been discovered. [...]
Scientists in Japan have developed a high-resolution X-ray telescope sharp enough to distinguish an object just 3.5 mm wide from one kilometer away, by combining precision mirror-making technology with space astronomy. To test its performance, they built a first-of-its-kind evaluation system, capable of simulating starlight on the ground to measure the telescope's sharpness before its launch on the US-Japan FOXSI sounding rocket mission. The findings, published in Publications of the Astronomical Society of the Pacific, represent a landmark achievement for Japanese X-ray astronomy and pave the way for high-resolution X-ray observations on future smaller satellites. [...]
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 Science Conference (LPSC), and is under assessment as a large-class mission for the 2030s. [...]
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. [...]
Going by the headlines, the matter seems to be settled. El País announces that Neanderthal men "chose" sapiens women. Science journal speaks of a "partner preference." National Geographic is already imagining the "Romeos" of prehistory. The Telegraph suggests that Neanderthals "had designs on" sapiens women. [...]
DNA studies of 1,500-year-old skeletons have revealed that ancient Koreans lived in tightly knit family networks where marrying close relatives was common in some cases, from powerful elites to individuals chosen for human sacrifice. [...]
Artificial intelligence is rapidly learning to autonomously design and run biological experiments, but the systems intended to govern those capabilities are struggling to keep pace. [...]
In the process of converting carbon dioxide into useful chemicals such as ethylene—a key precursor for plastics—a major challenge has been the flooding of electrodes, where electrolyte penetrates the electrode structure and reduces performance. KAIST researchers have developed a new electrode design that blocks water while maintaining efficient electrical conduction and catalytic reactions, thereby improving both efficiency and stability. [...]
Mutations in a key protein make a yeast found in dogs with common outer ear infections more resistant to the topical antifungals used to treat it, veterinarians and pathobiologists at the University of Illinois Urbana-Champaign found in a new study. The work is published in the journal Veterinary Dermatology. [...]
We've spent decades scratching the surface of Mars trying to uncover life there. But we've been searching a barren wasteland bombarded by radiation and bathed in toxic perchlorates. The entire time, it's likely that it's been too hostile to harbor extant life. So if we want a better shot at finding currently living life on Mars, we need to go underground. That is exactly the purpose of Orpheus, a proposed Mars vertical takeoff and landing (VTOL) hopper mission put forth in a paper presented by Connor Bunn and Pascal Lee of the SETI Institute at the 57th Lunar and Planetary Science Conference (LPSC). [...]
By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed more light on the X-ray variability of this object. [...]
As the West faces increasingly destructive wildfires, land managers rely on mechanical thinning to reduce hazardous fuels and restore forest health. But one obstacle continues to slow this work down: Thinning costs are notoriously difficult to estimate from one project to the next. Uncertainty around those numbers raises concerns that outdated cost estimates may be holding critical restoration projects back. [...]
Artemis II astronauts expressed awe on Saturday over their record-setting lunar flyby mission, urging unity on Earth after witnessing the planet's isolation like a "lifeboat" in space. [...]
Research and innovation in Texas A&M University's biomedical engineering department often centers around clinical impact on patients. Beyond the lab, however, some faculty are finding breakthroughs in the classroom. [...]
A pervasive narrative has taken hold in education: generative AI (genAI) is an unstoppable force, and educators must adapt or be left behind. [...]
Have you ever wondered how mussels instantly glue themselves to rocks, allowing them to survive the crushing force of ocean waves? They complete this process in under 30 seconds. Yet, in a laboratory, replicating this process of molecular self-assembly, known as liquid-liquid phase separation (LLPS), typically takes dozens of minutes, if not hours. A research team of The Hong Kong University of Science and Technology (HKUST) has recently solved this long-standing puzzle using large-scale molecular dynamics simulation and theoretical analysis, revealing the secret to nature's incredible speed and providing implications for instant biocompatible surgical glues. [...]
It has been said that Persian Gulf countries are both blessed and cursed by their vast oil and gas reserves. Geologic forces over millions of years have meant the region is an energy-rich global flash point, as it is now with a war underway that's causing a global energy crisis. [...]
Engineered cells are a high-value genetic asset that is key to many fields, including biotechnology, medicine, aging, and stem cell research, with the global market projected to reach $8.0 trillion USD by 2035. Yet the only ways to keep the cells safe are strong locks and watchful guards. [...]
Frightening headlines predicting a Super El Niño or even a Godzilla El Niño amp up anxiety levels for farmers and residents of bushfire-prone regions. [...]
The discovery of the oldest ever dog DNA suggests they have been our best friends for nearly 16,000 years—5,000 years earlier than had previously been thought, new research said Wednesday. [...]
Tiny robots—around 50 times smaller than the diameter of a human hair—open up fascinating possibilities: they enable the controlled manipulation of objects far too small for human hands. This brings us closer to a long-standing dream—the direct interaction with the microscopic world. [...]
Long before we had modern antibiotics to rely on, people often turned to traditional medicines from plants to treat infections. [...]
Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their own characteristic masses, spin behavior, and merger rate that may be linked to different dominant formation mechanisms. The paper outlining their results was submitted to the preprint server arXiv on March 18. [...]
A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as photon leakage or the peak in energy deposition of a fast charged particle (Bragg peaks), have been used to detect this kind of ordering. Prior to this study, there had been no direct, high-resolution in situ imaging of cavity-induced density-wave order in ultracold gases. [...]
For decades, the strongest evidence for the earliest human settlement in the Americas came from a site in Chile called Monte Verde. [...]
