In early 2024, laboratory-grown neurospheres (i.e. clusters of neural stem cells) were sent to the International Space Station (ISS) to be exposed to microgravity. The return trip was delayed several times due to bad weather in the landing zone. As a result, the cells were outside controlled culture conditions for longer than anticipated—beyond the limit of what they were expected to survive.
Evidence for hypernovae, theorized to be the most powerful explosions in the universe, has been disputed in two papers by University College London (UCL) researchers.
Former Ladue Police officer Julia Crews has maintained that she believed she had her TASER in her hand when she fired a shot into the back of a fleeing shoplifting suspect
The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple times. Using the Gemini North telescope, an international team co-led by Ilaria Caiazzo, assistant professor at the Institute of Science and Technology Austria (ISTA), captured the most detailed view yet of Pa 30, revealing striking new features of the remnant associated with a historical supernova witnessed nearly 850 years ago. The findings are published in The Astrophysical Journal.
After the gunfire exchange, the man abandoned the vehicle and attempted to carjack an occupied vehicle; Hartford officers shot the suspect, rendered medical aid and took him into custody
Earth seems like a troubled place right now, but at least our cosmic surroundings appear peaceful. This is not universally true, as explosions, collisions and other dangers lurk in other places and times.
Global positioning systems are a key feature in everyday life for much of the world’s population. Whether it’s ensuring a ship delivers its goods safely or helping you avoid a road closure on your commute home, GPS can help.
A research team led by the University of Osaka has directly observed, for the first time, an unusual heavy-fermion state forming at the boundary between a one-atom-thick material and a metal. Such states are closely linked to exotic quantum phenomena, including unconventional superconductivity, and the finding opens new possibilities for designing quantum materials through their interfaces.
Black holes, despite their extreme nature, are described by surprisingly few basic parameters: their mass, charge and spin. Two black holes may have formed for completely different reasons and passed through very different histories, yet still end up in the same final state. John Wheeler summarized this idea with the famous phrase “black holes have no hair.”
Francis Halzen wins Nobel Prize in physics for work on high-energy neutrinos of astrophysical originFrancis Halzen won the Nobel Prize in physics on Tuesday for his contributions to the IceCube Neutrino Observatory and his discovery of high-energy neutrinos of astrophysical origin.
Galactic black holes are cosmic mitochondria, powerhouses of the universe. Most of the energy these supermassive black holes produce comes from the material surrounding them: superheated plasma in their accretion disks interacting with tremendous magnetic fields. But there is a more direct way to extract energy from a black hole. It’s known as the Penrose process, and a new study asks whether we could discover a signature of this process.
The universe may be trapped in its own comfort zone, and a researcher in the College of Engineering and Computer Science has helped explain why it cannot seem to leave. A new study suggests the universe could be locked into its current state by the same kinds of quantum effects that scientists study when trying to preserve fragile information inside a quantum computer.
Like Earth, most planetary bodies circle their star in stable, detached orbits. These companionable systems can suddenly change when a planet comes too close to its star. In such a close encounter, a star can pull the planet in and swallow it whole.
The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material’s average crystal structure remains centrosymmetric, a study from Institute of Science Tokyo has found. Researchers demonstrated this in CuCrP2S6, a van der Waals material that transitions from a noncentrosymmetric to a centrosymmetric average structure. The finding challenges the conventional view of BPVE and suggests a new strategy for enhancing photoelectric conversion.
