Magnetic shielding for particle detectors
Particle physicists who hunt for neutrinos, cosmic-rays and other charged particles rely on sophisticated instruments that detect very faint bursts of light given off when incident particles interact with a medium. The most common such instruments, c.....»»
Volcanic eruption: Scientists perform volcanic scenarios to develop response plan
What would happen if a volcano were to erupt tomorrow in New Mexico? How prepared as we as a society for an event like this to occur? When volcanic unrest occurs, both academic and government agencies need to have advanced fundamental understanding o.....»»
X-rays reveal all the differences between authentic AirPods and counterfeits
Counterfeit Apple products are a real problem. Earlier this year we saw US officials seize over a thousand fake AirPods and Apple Watches. And Apple has a dedicated team for dealing with illegal knockoffs. While good counterfeits may look very convin.....»»
Supermassive black hole found only half a billion years after Big Bang

One of California"s riskiest volcanoes is very active. Is an eruption coming?
One of California's riskiest volcanoes has for decades been undergoing geological changes and seismic activity, which are sometimes a precursor to an eruption, but—thankfully—no supervolcanic eruptions are expected......»»
What caused the volcanic tsunami that devastated a Greek island 373 years ago?
Kolumbo underwater volcano's 1650 eruption killed 70 people on Santorini Island, Greece. Enlarge / This view from an international volcano monitoring system shows the Kolumbo volcanic crater on the seafloor. (credit: SANTORY ).....»»
How close is too close to a kilonova?
Cataclysmic events happen in the universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of others. Most of them happen in distant galaxies, so they pose no threat to us. But there are a few that could affect life on.....»»
Sable Island"s shifting landscape offers insights into groundwater loss globally
Almost 200 kilometers off the coast of Nova Scotia sits a slender, crescent-shaped spit of land known for mythic wild horses that roam its dunes, seals that dot its low-slung shores and hundreds of shipwrecks still populating its watery depths......»»
New study shows Hunga-Tonga Hunga-Ha"apai eruption depleted ozone layer
A large team of atmospheric specialists has found that when the Hunga-Tonga Hunga-Ha'apai volcano erupted last year, it took part of the ozone layer with it. Their findings are published in the journal Science......»»
Realizing vertical ultraviolet-B semiconductor laser diodes for high optical output
Ultraviolet (UV) rays are electromagnetic waves with wavelengths ranging from 100 to 380 nanometers (nm). These wavelengths can be classified into three regions: UV-A (315–380 nm), UV-B (280–315 nm), and UV-C (100–280 nm), with the latter two c.....»»
Scientists present the first set of global maps showing geographic patterns of beta-diversity in flowering plants
Beta-diversity serves as a crucial metric for gauging shifts in species composition over spatial or temporal scales, bridging the spectrum between localized (alpha) and broader regional (gamma) diversity. In the fields of ecology, biogeography and co.....»»
