Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and uncertainty both surpassing the 10⁻¹⁹ level, meaning the clock would lose or gain less than one second over roughly 30 billion years. Go to Source […] For the first time, physicists have demonstrated that a material’s superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team led by Itai Keren at Columbia University show how quantum properties can be deliberately engineered by bonding carefully chosen materials together—without applying any external light, pressure, […] In physics, the mesoscale lies between the microscopic and the macroscopic. It is not just the domain of tiny living creatures like small larvae, shrimp, and jellyfish, but also where physics equations become extreme. While the macroscopic realm is governed by inertia and the microscopic by viscosity, the mesoscale is both and neither, requiring a […] Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard University showed how extremely weak light signals could be detected across a fiber link spanning more than 1.5 km—possibly paving the […] Look up on a clear night and you’ll see the streaks of our new space age. What you don’t see is the growing fallout for the atmosphere that keeps us alive. Go to Source The two men had entered an icy marsh to locate a dog but were unable to get out; Onondaga County Sheriff’s Office deputies rescued them with air support Go to Source Under the new bill the state commission could remove sheriffs who have felony convictions, are prohibited from owning guns or have not served in LE for the required five years Go to Source Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets we’ve found so far—which in turn makes them interesting for astrobiological surveys. However, there’s a catch—astrobiologists aren’t sure the light from these stars can actually support oxygen-producing life. A new paper, available on […] About 15% of asteroids near Earth have small moons orbiting them, making binary asteroid systems common in our cosmic neighborhood. Go to Source Life’s capacity to survive in simulated lunar and Martian soils has been explored in two papers published in Scientific Reports. Treating simulated lunar soil with both symbiotic fungi and worm-produced compost can significantly improve the likelihood of reproduction for chickpea plants growing in the soil, indicates one study. A separate paper suggests that some microbes […] Superconductivity is a quantum state of matter characterized by an electrical resistance of zero and the expulsion of magnetic fields at low temperatures below a critical point. Superconductors, materials in which this state occurs, have proved to be highly advantageous for the development of various technologies, including medical imaging devices, particle accelerators and quantum computers. […] Ever since physicist Freeman Dyson first proposed the concept in 1960, the “Dyson sphere” has been the holy grail of techno-signature hunters. A highly advanced civilization could build a “sphere” (or, in our more modern understanding, a “swarm” of smaller components) around their host star to harvest its entire energy output. We know, in theory […] Italian astronomers have performed extensive spectroscopic monitoring of a recently discovered nova known as Vulpeculae 2024, also known as V615 Vul. Results of the new observations, presented in a paper published in the Astronomy & Astrophysics journal, shed more light on the nature of Vulpeculae 2024, suggesting that it represents a rare class of hybrid […] Video shows Taunton Police officers aiding residents out of the home and working to dig fire hydrants out of deep snowbanks Go to Source Four years ago, NASA purposely smashed a spacecraft into a small asteroid to see if they could deflect it—a test to prove humanity could protect Earth from threatening space rocks.
