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 / 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 / How animals communicate to work together across species boundaries
An international team of researchers have published a new review in Animal Behavior revealing how communication enables cooperation between different animal species. The review, titled "The ecology and evolution of cues and ...
Phys.org / Powerful seismic waves from Japan's 2011 earthquake struck Earth's core and bounced back up, moving the island eastward
In 2011, Japan reeled from the effects of a devastating magnitude 9.0 earthquake. But unnoticed in the chaos resulting from the quake, its major aftershocks and the tsunami it caused, something strange happened. About 16 ...
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 / 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 / From birds to fish, how extreme heat causes wildlife to suffer
Like humans, wildlife is increasingly vulnerable as climate change fuels longer and more intense heat waves, disrupting feeding and breeding and, in extreme cases, proving fatal.
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 / AI reveals unexpected source of antibiotic candidates in prion proteins
New antibiotic candidates for drug-resistant bacteria may reside inside prions, misfolded proteins in the brain best known for rare and fatal degenerative brain diseases. Prion and prion-like proteins may hide short peptides, ...
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, ...
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 ...
