Phys.org / Webb unveils nature of distant ultraviolet-luminous galaxy CEERS2-588
Astronomers from the University of Tokyo in Japan and elsewhere have employed the James Webb Space Telescope (JWST) to observe a distant ultraviolet-luminous galaxy known as CEERS2-588. Results of the observational campaign, ...
Phys.org / US to scrap cornerstone of climate regulation this week
President Donald Trump's administration is expected to finalize this week its repeal of a foundational scientific determination that underpins the US government's authority to regulate greenhouse gas pollution.
Phys.org / Nature's 'engine is grinding to a halt' as climate change gains pace, says study
Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats ...
Phys.org / Promise the Earth: Why real climate action means restraint
A new book by a Cambridge engineer and an Oxford theologian argues that our faith in technology to solve the climate crisis is distracting us from the uncomfortable truth: that saving the planet is neither a task for future ...
Phys.org / The 'Little red dots' observed by Webb were direct-collapse black holes
The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the universe has evolved ...
Phys.org / Pulsar timing hints at a nearby dark matter 'sub-halo'
A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar neighborhood. Reporting their findings in Physical Review Letters, a team led by Sukanya Chakrabarti ...
Phys.org / Scientists discover 'levitating' time crystals that you can hold in your hand
Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create commercial or industrial ...
Phys.org / Building blocks of life discovered in Bennu asteroid rewrite origin story
Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA's OSIRIS-REx mission. How those amino acids—the ...
Phys.org / Escape from Fukushima: Pig-boar hybrids reveal a genetic fast track in the wake of nuclear disaster
A new genetic study examines an unusually large hybridization event that followed the Fukushima nuclear accident, when escaped domestic pigs bred with wild boar. The research shows that domestic pig maternal lineages sped ...
Phys.org / Leading AI models struggle to solve original math problems
Mathematics, like many other scientific endeavors, is increasingly using artificial intelligence. Of course, math is the backbone of AI, but mathematicians are also turning to these tools for tasks like literature searches ...
Medical Xpress / Why working out may not help you lose weight
According to conventional wisdom, a great way to lose weight is to do some exercise. While being active is beneficial in many ways for our health, it may not be very helpful if you want to shed a few inches off your waistline. ...
Medical Xpress / Lucid dreaming could be used for mental health therapy, new study says
Lucid dreaming (LD) is one of the most fascinating parts of human consciousness, where you realize you are actually dreaming while you're still asleep and, in some situations, can decide what happens next. There is a growing ...
