Phys.org / Tiny objects swimming in a superfluid of light move against the flow
Superfluids are intriguing states of matter in which particles behave like a giant collective wave, allowing them to flow without any friction. When this fluid flows past a fixed obstacle at a velocity below a specific threshold, ...
Phys.org / Younger adults overlook nearby biodiversity as species names fade from memory
Many young adults are familiar with common species such as dandelions or sparrows. In contrast, plants and birds typical of fields, meadows and other agricultural habitats are significantly less well known. This is shown ...
Phys.org / The Sun may not engulf Earth after all, scientists say
Need some good news on a Friday after a long week? The Earth may not be engulfed by the expanding fireball of the dying sun, which has long been assumed to be our home planet's ultimate fate, according to scientists.
Phys.org / New JWST images of abnormally well-developed galaxy cluster open up the 'cosmic noon' frontier
A stunningly concentrated and hefty galaxy cluster, from a time in the universe's history when such massive structures aren't expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of ...
Phys.org / Bullet Cluster observations reopen dark matter debate with MOND-compatible explanation
The Bullet Cluster has so far been considered evidence of the existence of dark matter. An international team of researchers has now analyzed new data and current images from the James Webb Space Telescope (JWST). According ...
Phys.org / Plant hormones in mammals challenge view of cytokinins as purely botanical
In biology, cytokinins were long considered regulators exclusive to the plant kingdom, where they control, among other things, growth and responses to stress. Until now, little research has been conducted into whether these ...
Phys.org / Palm oil, coconut and soybean drive more species extinction than previously thought
Oils from crops such as coconut, palm oil and soybean are used in a range of applications, from cosmetics and makeup to margarine and spreads, and from medicines to animal feed. These oil crops, as they are known, are increasingly ...
Phys.org / Student makes first recorded sighting of a microwhip scorpion in the Daintree Rainforest
A James Cook University Ph.D. student's late-night solo survey has led to the first recorded sighting of a microwhip scorpion in the Daintree Rainforest. JCU entomologist and taxonomist Matthew Connors works at the university's ...
Phys.org / How H5N1 bird flu hid unrecognized for weeks in dairy cattle
When H5N1 bird flu first began infecting U.S. cattle in early 2024, diagnosis was elusive because, in cows, the disease looked completely different. Instead of affecting the lungs, as H5N1 does in other mammalian species, ...
Phys.org / Arabian Sea humpback whale's long-distance trip further highlights species' unique ecology
Off Oman's coast lives a small population of just over 80 Arabian Sea humpback whales (ASHWs). They are classified as endangered and are thought to be the only humpback whale population that doesn't undertake seasonal migrations ...
Phys.org / Hidden underground, fungi drive carbon storage, crop health and ecosystem stability
Fungi are key constituents of the soil microbial community, playing a major role in moving carbon and energy through the soil food web. A recent analysis carried out by Professor Matthias C. Rillig from Freie Universität ...
Phys.org / A new way to control tiny quantum light sources by twisting atomically thin layers of hexagonal boron nitride
In a paper published in Science Advances, researchers at the University of Technology Sydney (UTS) in collaboration with the University of Minnesota and Kyung Hee University have found a new way to control quantum light sources, ...
