If you want to understand the origins of black holes, Yale astronomers say, you need to look beyond the centers of galaxies and start searching in the nooks and crannies. That’s where you’ll find the “wanderers”—black holes whose journeys may tell the story of how the first black holes formed. Go to Source […] Studying exoplanets has given astronomers insights into the characteristics that could help them find life beyond Earth. For years, astronomers thought an exoplanet’s location in a star’s habitable zone was enough to make it an Earth-like world. But some stars are more active than our sun, exposing planets in their habitable zones to far more […] A three-point sling on the AR-15 that the deputy was using to drill a support-side shoulder transition became caught on his ear muffs, causing him to lose control of the rifle, the suit claimed Go to Source The L.A. Board of Police Commissioners approved a three-month pilot program with Axon Enterprise that will outfit some city-owned street lights with ALPR cameras at no cost to the city Go to Source Asteroids don’t come with a warning label that they might one day hit Earth. While we don’t know of any currently on course to do so, we are finding thousands of new ones each year, and there’s always a chance that one could. Go to Source Conditions on early Earth may have become stable enough to sustain the chemistry associated with the origins of life around 4.33 billion years ago, according to new research co-led by Planetary Science Institute senior scientist Oleg Abramov. Go to Source Broward County commissioners voted unanimously not to renew the Sheriff’s Office fire-rescue agreement after 2028, returning roughly 900 employees and oversight of the department to the county Go to Source Switching to modern silicon solar cells could cut the cost of powering satellites by as much as 90% based on beginning-of-life (BOL) performance, according to a review led by the University of Surrey. The switch to silicon cells could also halve the weight of the solar cells needed on a spacecraft, freeing mass for fuel […] A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to particle-antiparticle formation on a quantum simulator, among the first such observations in quantum physics. Go to Source Unlike electric charge, as far as we know all mass is positive, and positive masses attract one another. Could negative mass exist, and if so, what would be the ramifications? Go to Source Go to Source Britain announced Wednesday that it will launch a new military space squadron to defend the country’s satellites, the latest move as countries race to develop military space capabilities. Go to Source A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird’s magnetic sense depends on exactly that: Turning through Earth’s magnetic field would produce tiny electrical signals inside its ears. However, a theoretical study suggests that this miniature generator cannot supply directional information fast enough to work as […] Creating a perfect crystal sounds straightforward: Arrange identical building blocks into a repeating, orderly structure. At the microscopic scale, though, even subtle biases in how particles interact can push them in preferred directions, making it harder to form uniform crystalline materials. Go to Source A team led by University at Buffalo physicists has found a mathematical solution that shows how a frustrated quantum magnet can transition from ultraslow behavior to ultrafast, highly entangled behavior resembling that of a black hole.
