A new class of magnetism called altermagnetism has been imaged for the first time in a new study. The findings could lead to the development of new magnetic memory devices with the potential to increase operation speeds of up to a thousand times.
Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists at the University of California, Davis have identified new clusters of cells with…
University of Liège researchers discover a new planetary system around a particularly small and cool star.
Researchers from Inserm and Université de Rennes recently identified a new bacterial toxin which they transformed into potent antibiotics active against various bacteria responsible for human infections.
Multisystem inflammatory syndrome in children (MIS-C), believed to be linked to COVID-19, damages the heart to such an extent that some children will need lifelong monitoring and interventions, said the senior author of a medical literature review published Sept. 4 in EClinicalMedicine, a journal of The Lancet. Case…

For some time, I’ve argued that a common conception of AI is misguided. This is the idea that AI systems like large language and vision models are individual intelligent agents, analogous to human agents. Instead, I’ve argued that these models are “cultural technologies” like writing, print, pictures, libraries…
By trapping light into tiny crevices of gold, researchers have coaxed molecules to convert invisible infrared into visible light, creating new low-cost detectors for sensing.
Running a biotech company is capital intensive, and this can make it intimidating to get started. Founders sometimes face a chicken and egg problem: how do you make progress without millions of dollars in funding, and how do you raise millions of dollars in funding without having made progress? However, it is quite…
Engineers used the flow of water over a crystal plate to generate a stable ring of plasma without a vacuum chamber or electromagnetic fields to contain it.
A club for Meccano enthusiasts in London, holding four meetings each year and a public Meccano Show in Falconwood.
If you're working on serious projects there are often serious risks. A lot of these can be mitigated by preventative measures and safety ge...
Media Advisory: Press Conference at ESO HQ Announcing Unprecedented Discovery
A dual-mode ramjet was developed and tested in less than 11 monthsTesting demonstrates a threefold increase in airflow compared to previously flight-tested hypersonic technology
New analysis finds tests for new doctors can measure what matters — the life and health of patients
A team mapping radio waves in the Universe has discovered something unusual that releases a giant burst of energy three times an hour, and it’s unlike anything astronomers have seen before. The team who discovered it think it could be a neutron star or a white dwarf—collapsed cores of stars—with an ultra-powerful…
Study implicates changes to way DNA is organized, regulated rather than changes to genetic code
A figure from the study showing rock dripping from the craton. The researchers hypothesize that the dripping is caused by…
In a world first, a team led by researchers at Penn State used two-dimensional materials, which are only an atom thick and retain their properties at that scale, unlike silicon, to develop a computer capable of simple operations. The advancement, published in Nature, represents a major leap toward the realization of…
