Phys.org / Gravitational waves reveal hidden structure of galactic centers
A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The ...
Phys.org / Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST ...
Phys.org / Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to ...
Phys.org / Largest known Mesozoic crocodyliform egg clutch discovered in Brazil
In a study published in the Journal of Vertebrate Paleontology, researchers Dr. Giovanna M. X. Paixão and her colleagues analyzed the fossilized remains of three Upper Cretaceous egg clutches. One of these clutches, totaling ...
Phys.org / Many scientists now use AI but fail to disclose it, study finds
When scientists employ generative AI tools like ChatGPT to help with tasks such as editing and translation for their academic writing, many journals now ask them to disclose this assistance. The rules are intended to maintain ...
Phys.org / A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest
Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and develop quantum technologies, ...
Phys.org / Material previously thought to be quantum is actually a new, non-quantum state of matter
Magnetic materials in a quantum spin liquid phase are of great interest in the pursuit of exotic state of matter and quantum computation. But in the quantum realm, things are not always what they seem. A study, published ...
Phys.org / Stars like our sun may maintain the same rotation pattern for life, contrary to 45 years of theoretical predictions
Researchers at Nagoya University in Japan have conducted the most detailed simulation of the interior of stars and disproved a theory scientists have believed for 45 years: that stars switch their rotation patterns as they ...
Phys.org / New study reveals differences between 'Demon Slayer' bamboo muzzle and actual bamboo
In storytelling, even small visual details can become unforgettable. In the globally popular anime "Demon Slayer," one such detail is the short bamboo muzzle worn by a central character. It looks simple and believable, just ...
Phys.org / Simultaneously decoding the transcriptome, epigenome and 3D genome within a single cell
The origin of many diseases begins at the cellular level and involves multiple molecular interactions. However, previous methods have struggled to accurately observe changes in individual cells. Analyzing average values across ...
Phys.org / What's inside neutron stars? New model could sharpen gravitational-wave 'tide' clues
Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of any known objects, surpassed ...
Phys.org / Water-window X-rays without a synchrotron: How graphite flakes could shrink bioimaging tools
Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the "water window." This new method holds promise in making bioimaging ...
