Phys.org / Quantum semiconductor design could expand search for dark matter
Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that ...
Phys.org / JWST discovers a new barred spiral galaxy
An international team of astronomers reports the discovery of a new massive barred spiral galaxy. The newfound galaxy, designated M1149-BSG-z5, was identified using the James Webb Space Telescope (JWST). The finding was detailed ...
Phys.org / Researchers recreate a lost Ming Dynasty goldworking technique to make replica royal jewelry
Chinese goldsmiths working during the Ming Dynasty were masters of their craft, capable of creating intricate and elaborate jewelry pieces. The evidence is there in the abundance of finds in royal and noble tombs across Hubei ...
Phys.org / Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy measure
Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, ...
Phys.org / Solar storms leave their mark on cosmic rays that reach Earth
A new study has revealed an unexpected link between solar storms and the flux of high-energy cosmic rays arriving at Earth. The findings, made using one of the world's largest cosmic ray detectors, could open up a new way ...
Phys.org / The universe is less uniform than we thought—cosmology may need a radical rethink
Modern cosmology rests on a simple assumption: If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle.
Phys.org / Europe's deadly heat wave scorches east, Slovakia hits record
Europe's most severe heat wave on record set new temperature records in eastern parts of the continent on Monday and forced Ukraine to order power cuts to cope.
Phys.org / Natural born killers—tracking immune cells as they cluster around cancer
There is a constant war going on in your body. Working against you are viruses and cancer cells growing uncontrollably, threatening your tissues and organs. Fighting on your side are immune cells such as lymphocytes, a type ...
Medical Xpress / Ovaries may take on job in immune system after their tenure as reproductive organs
For most women, the body begins to change dramatically in their 40s or 50s. This transition, known as menopause, is defined as 12 consecutive months without a menstrual period, marking the end of the reproductive years. While ...
Phys.org / Songs play a greater role than plumage color in limiting bird hybridization, study suggests
When trying to attract and recognize potential mates, animals are known to rely on various signals, traits and behaviors. In the case of birds, these signals can typically include a wide range of sounds—such as trills, whistles, ...
Medical Xpress / 1 in 5 adults make health decisions based on what they see on social media despite widespread mistrust
Every few scrolls, another health expert appears on the screen. While some are genuinely qualified, others simply sound convincing enough to pass as one. With AI-generated content flooding feeds, avoiding such advice is becoming ...
Science X / Cleaner skies, sizzling summers: How falling pollution may amplify Europe's heat
Cities from Paris to Prague have sweltered under record-breaking heat waves in recent years. In fact, Western Europe's average summer temperature has climbed by roughly 2.3°C since 1980, about triple the 0.8°C global rise. ...
