Ukraine’s Clashing Atomic Fuel Dilemmas
Last Friday Ukrainian transmission grid operator Ukrenergo marked one year of war with a hopeful milestone—two straight weeks without rolling blackouts. For sure, some cities at the front suffered outages. But the big picture was clear: Power engineers had delivered the grid through the worst of the winter and Russia’s onslaught, including hundreds of missiles…

It exists after all — ScienceDaily
An international team of researchers under the leadership of Dr Florian Peißker at the University of Cologne’s Institute of Astrophysics has discovered a very young star in its formation phase near the supermassive black hole Sagittarius A* (Sgr A*) at the centre of our Milky Way. The star is only several tens of thousands of…

Super-fast insect urination powered by the physics of superpropulsion — ScienceDaily
Saad Bhamla was in his backyard when he noticed something he had never seen before: an insect urinating. Although nearly impossible to see, the insect formed an almost perfectly round droplet on its tail and then launched it away so quickly that it seemed to disappear. The tiny insect relieved itself repeatedly for hours. It’s…

Liquid nitrogen spray could clean up stubborn moon dust — ScienceDaily
A liquid nitrogen spray developed by Washington State University researchers can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts. The sprayer removed more than 98% of moon dust simulant in a vacuum environment with minimal damage to spacesuits, performing better…

Study reveals new details about the universe’s chemical formation — ScienceDaily
Using data from the James Webb Space Telescope’s first year of interstellar observation, an international team of researchers was able to serendipitously view an exploding supernova in a faraway spiral galaxy. The study, published recently in The Astrophysical Journal Letters, provides new infrared measurements of one of the brightest galaxies in our cosmic neighborhood, NGC…

Will future computers run on human brain cells? Breaking ground on new field of ‘organoid intelligence’ — ScienceDaily
A “biocomputer” powered by human brain cells could be developed within our lifetime, according to Johns Hopkins University researchers who expect such technology to exponentially expand the capabilities of modern computing and create novel fields of study. The team outlines their plan for “organoid intelligence” today in the journal Frontiers in Science. “Computing and artificial…

Astronomers discover metal-rich galaxies in early universe — ScienceDaily
While analyzing data from the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell University astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy — one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at…

The device could help workers locate objects for fulfilling e-commerce orders or identify parts for assembling products. — ScienceDaily
MIT researchers have built an augmented reality headset that gives the wearer X-ray vision. The headset combines computer vision and wireless perception to automatically locate a specific item that is hidden from view, perhaps inside a box or under a pile, and then guide the user to retrieve it. The system utilizes radio frequency (RF)…

The rediscovery of an ethereal fairy lantern brightly illuminates their mysterious past — ScienceDaily
Green leaves and photosynthesis were once considered key features of plants. However, some plants have since abandoned this process, obtaining their nutrients from other organisms. One such plant is the genus of Thismia, commonly known as fairy lanterns, which is characterised by its unusual appearance, elusiveness, and lack of photosynthesis. Fairy lanterns are rare and…
