How far the Milky Way's disk extends has long been difficult to define—it doesn't end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of astronomers has identified the edge of the Milky Way's star-forming disk by studying the
An Iranian propaganda video depicts Donald Trump, Netanyahu and Satan as Lego figurines, the White House combines real footage of airstrikes with clips from films and video games, and the American president shares AI-generated videos of himself as a fighter pilot. It sounds
When supermarkets choose the right strategy for surplus food, they can both reduce food waste and improve their bottom line. An analysis from the University of Copenhagen shows that it is often more profitable to donate surplus food than to throw it away. In many cases, doing
Perovskite quantum dots are considered promising materials for LEDs, photocatalysis, and future quantum light sources. Researchers at LMU Munich have managed to master two major hurdles in working with these quantum dots: their stability in solution and precise control of their
Diamond is among the hardest naturally occurring substances on Earth, but if you shrink it down to the nanoscale, it is surprisingly elastic. And that could be useful for a host of applications such as quantum computing. In a paper published in the journal Physical Review X,
Following the recent successful test flight of NASA's Artemis II mission around the moon, NASA rolled out the core stage, or the largest section, of the agency's SLS (Space Launch System) rocket that will launch the crewed Artemis III mission in 2027. The stage departed from

Marburg virus disease (MVD) is a severe and often fatal hemorrhagic disease in humans caused by the Marburg virus. It is carried by Egyptian fruit bats and can spread to people after exposure in caves or mines where they live. So imagine the surprise of researchers when they
As more families and small enterprises enter the egg market and more consumers buy local food, the stakes around backyard egg safety are growing. A single outbreak linked to small producers could pose a setback to public confidence in locally sourced food at a critical moment
Researchers from Bar-Ilan University have successfully recreated key features of black hole physics in a laboratory setting using an innovative optical system that mimics how black holes behave after violent cosmic events such as collisions or mergers.
Tiny dinosaur fossils that puzzled scientists for over 20 years have finally revealed their true identity. Rather than belonging to a miniature species, they are actually baby ankylosaurs—some less than a year old, including a possible hatchling. By studying bone growth
Melbourne home sellers and landlords lost up to $55 million a week as sales prices and rents declined after the second severely restrictive COVID-19 lockdown (July 2020) to attract buyers and renters who were relocating to less restrictive lockdowns outside the city, a QUT-led
This announcement from the FBI came after President Donald Trump highlighted the recent deaths of several scientists and government workers who may have had access to sensitive information
Deep inside planets like Uranus and Neptune, scientists may have uncovered a bizarre new state of matter where atoms behave in unexpected ways. Advanced simulations suggest that carbon and hydrogen, under crushing pressures and scorching temperatures, can form a strange hybrid
For decades, scientists have worked to improve predictions of El Niño-Southern Oscillation (ENSO), a climate powerhouse that can cause droughts, flooding, marine heat waves, and more around the world. Researchers from the University of Hawai'i at Mānoa have published a study in
Floatable beads made from chitosan and cellulose acetate and enhanced with bentonite have been engineered to effectively clean oil from water. The beads showed good oil adsorption capacity while remaining easy to collect from the water surface.
Journalist Kevin Hartnett chronicles how code-checking tools and AI are being used to tackle difficult math problems.
A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical patterns without expensive manufacturing tools. Scientists even etched a
A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains. This occurs because resistant
Scientists have unveiled a breakthrough imaging method that can capture the hidden details of events unfolding in trillionths of a second. This new technique doesn’t just track how bright something is—it also reveals subtle structural changes that were previously invisible, all
Invisible "dark matter"—what cosmologists call the mysterious glue that holds everything together—is estimated to make up more than a quarter of the universe. In chemistry, dark matter refers to the thousands of small molecules in bone and tissue that can't be identified using
Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as it ultimately allows them to represent binary digits (i.e., "0" and "1") when
A quantum spin liquid is a phase of matter in which the magnetic moments in a material do not align or freeze, even at temperatures close to absolute zero (i.e., at 0 K). The experimental realization of this highly dynamic state could have important implications for the
