Phys.org / Space telescopes track nearby quasar's dramatic X-ray state transition
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 ...
Phys.org / Astronomers find evidence for three subpopulations of merging black holes
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 ...
Phys.org / After Artemis II, NASA looks to SpaceX, Blue Origin for moon landings
With Artemis II successfully completing its historic lunar mission on Friday, NASA is banking on billionaires Jeff Bezos and Elon Musk for the next step: landing astronauts on the moon.
Phys.org / Scientists turn 'mess' into breakthrough: Chaotic design unlocks next-generation optical devices
Researchers from the Monash University School of Physics and Astronomy have flipped a long-held assumption in optics, showing that deliberately introducing controlled disorder into ultra-thin optical devices can dramatically ...
Phys.org / AI trained like a Rubik's Cube solver simplifies particle physics equations
For years, Rutgers physicist David Shih solved Rubik's Cubes with his children, twisting the colorful squares until the scrambled puzzle returned to order. He didn't expect the toy to connect to his research, but recently ...
Phys.org / Street green space can help cool cities, but it will not be enough on its own
A new IIASA-led study finds that expanding street green space can reduce urban heat stress in cities worldwide, but even ambitious greening efforts are unlikely to offset a significant share of the additional heat expected ...
Phys.org / Heat from traffic is contributing to rises in city temperatures, study finds
Scientists at The University of Manchester have developed a new way to measure how traffic contributes to rising urban temperatures, revealing that everyday vehicle use can play a measurable role in making cities warmer. ...
Phys.org / Water conservation works, but climate change is outpacing it: Phoenix, Denver and Las Vegas show the future
When a drought turns into an urban water crisis, a city's first step is often to limit lawn watering and launch a campaign to encourage everyone to conserve. It might raise water-use rates or offer incentives for installing ...
Medical Xpress / As RSV evolves, a two‑pronged antibody cocktail aims to stay ahead
Scientists in China have developed a two-antibody cocktail to treat respiratory syncytial virus, or RSV, that in laboratory studies prevented the virus from developing drug resistance—a persistent problem with current therapies ...
Phys.org / Hackers meet their match: New DNA encryption protects engineered cells from within
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 ...
Phys.org / Advanced mirror technology now powers a breakthrough X-ray telescope
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 ...
Dialog / Scientists build arsenic-lined crystal pore framework to boost rhodium catalyst performance
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, ...
