Researchers have developed a new computational method to explore the neutron matter inside neutron stars at densities higher than previously studied.
This method provides insights into the behavior of neutrinos during supernova explosions, enhancing the accuracy of simulations and potentially improving our understanding of such cosmic events.

Researchers from City University of Hong Kong (CityUHK) and local collaborators have made a groundbreaking discovery of a new vortex electric field, poised to revolutionize future electronic, magnetic, and optical devices. This research holds immense promise for significantly enhancing the performance of various devices, particularly by improving memory stability and accelerating computing speeds.
SACRAMENTO — A magnitude 5.5 earthquake that struck in a remote area of Nevada on Monday afternoon sent shaking throughout Central California, including the Sacramento area.
In Sacramento, one person saw ornaments on a Christmas tree sway, as did some blinds for less than a minute. Water sloshed in a swimming pool, another person said. In Davis, a computer swayed for just a few seconds and a desk chair was jolted, while a young man reported feeling his bed sway and an unnerved poodle sought comfort.
In Reno, about 50 miles northwest of the quake’s epicenter, someone at KTVN-TV captured a video of the star on the newsroom’s Christmas tree still quivering — barely — as staffers scrambled to cover the earthquake. One person could be heard saying they hadn’t felt anything.
We tie our shoes, we put on neckties, we wrestle with power cords. Yet despite deep familiarity with knots, most people cannot tell a weak knot from a strong one by looking at them, new Johns Hopkins University research finds.
Researchers showed people pictures of two knots and asked them to point to the strongest one. They couldn’t.
They showed people videos of each knot, where the knots spin slowly so they could get a good long look. They still failed.

Biobanks are an obvious use case for DNA data storage. “With this technology, you could convert a biobank that is the size of a football field into something that can fit with everything in the palm of your hand,” says Banal. With encapsulation technologies, the DNA samples can be stored at room temperature. Compared to storing samples in freezing conditions in conventional biobanks or data centers that require extensive cooling, this has significantly lower energy consumption.
Until recently, scientific and medical applications were the sole drivers behind storing data in DNA. New research could broaden its scope to cryptography and nanotechnology. Another interesting development is the emerging intersection of DNA data storage and DNA computing. Indexing methods for DNA data retrieval mentioned earlier are an early example of that. Today, one of the most pressing commercial drivers of the technology is the data centers.
As researchers and startups chip away at its limitations, DNA data storage is becoming a viable commercial solution for storing all kinds of data at scale. The DNA Data Storage Alliance, a consortium founded in 2020, counts legacy data storage giants such as Western Digital and Seagate among its members.
Scientists at UCL and the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology) have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of “smart tattoo” with a range of potential uses.
The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos. That is, the OLEDs are fabricated onto temporary tattoo paper and transferred to a new surface by being pressed on to it and dabbed with water.
The researchers, who described the process in a new paper in the journal Advanced Electronic Materials, say it could be combined with other tattoo electronics to, for instance emit light when an athlete is dehydrated, or when we need to get out of the sun to avoid sunburn. OLEDs could be tattooed on packaging or fruit to signal when a product has passed its expiry date or will soon become inedible, or used for fashion in the form of glowing tattoos.
Currently, dark matter detection requires specialized laboratories with costly equipment. ODIN has the potential to overcome this limitation.
“ODIN’s sensitivity is primarily dependent on phonon density rather than target volume, in contrast to existing systems. This feature may enable compact, low-cost detectors, with the ability to perform lock-in dark matter detection by periodically depopulating the phonon mode,” the study authors explain.
Moreover, the proposed device design features only one optomechanical cavity. Instruments with multiple cavities could result in more exciting results.
