Phys.org / Webb spots possible early-universe supernova just days after it happened
The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-forming galaxy at a redshift of 5.017 and was ...
Phys.org / New spectroscopy method enables direct comparisons of nuclear sizes across heavy elements
The size of a nucleus (nuclear charge radius) is an important physical quantity that reflects the arrangement of protons and neutrons within the nucleus. Particularly in deformed nuclei, such as those of rare-earth elements, ...
Phys.org / Newly discovered viruses reveal an evolutionary missing link
Researchers at the University of Miami have identified a group of previously unknown viruses that bridge an evolutionary gap between viruses and cellular protein compartments, a discovery with implications for both biotechnology ...
Medical Xpress / Ethnic inequalities in stroke explained by differences in stroke risk factors
Stroke risk is primarily linked to differences in traditional stroke risk factors, like diabetes and high blood pressure, rather than ethnicity, according to findings from a new south London study conducted at King's College ...
Phys.org / Rabbits were a medieval royal luxury in England—until the Black Death made them commonplace
The European rabbit is a common sight in the British countryside today. Yet it was not always so. They are not native to the British Isles and are one of the most devastating invasive species.
Phys.org / A distant supercluster of galaxies points to self-interacting dark matter
Seven billion light-years from Earth, there is an unexpected cluster of galaxies. It has two regions in the process of colliding with each other with a combined mass of more than two quadrillion solar masses. Given its mass, ...
Phys.org / New sensor uses slowed light to detect gravitational pull of tiny objects
Gravity, the attraction between objects with mass, is the weakest of the four fundamental forces governing physical processes. Detecting the tiny gravitational pull of objects that are just a few millimeters in size and have ...
Phys.org / Your dog may link sounds with shapes, just like you do
Sounds have shapes. That might sound strange since sound waves are invisible, but a famous psychological experiment in the 1920s showed that our brains naturally link spoken sounds to visual forms. According to new research ...
Medical Xpress / Changing signal rhythms shifts balance of cell types in miniature gut models
A study conducted at the Hubrecht Institute reveals that the intestines use the rhythm of a signal to decide which cells to make. Researchers from the Sonnen group discovered that chemical signals oscillate at different rhythms ...
Phys.org / AI turns scrap impurities into useful ingredients for stronger recycled iron
About 2 billion metric tons of metal are produced worldwide every year to meet the demands of industry, infrastructure and the energy sector. Much of this production still relies on primary raw materials, contributing to ...
Phys.org / Mushroom-derived peptides boost saltiness by up to 70%, offering a path to low-sodium foods
Scientists have found a way to make salt taste saltier without increasing its sodium content, a welcome development in the culinary world. Salt is a powerful flavor enhancer, drawing out the subtle flavors of a dish while ...
Tech Xplore / AI is coming for every company, Nvidia boss says
Artificial intelligence will ultimately become a key aspect of all companies, the head of AI chip giant Nvidia said during a visit to Stockholm, where he urged Europe to ramp up its AI industry.
