Physicists shine new light on an old quantum optics problem about collective behavior
When atoms interact with each other, they behave as a whole rather than individual entities. That can give rise to synchronized responses to inputs, a phenomenon that, if properly understood and controlled, may prove useful for developing light sourc.....»»

High-end Intel CPUs have seen issues with crashing over the past several months, but we might have some settings that can mitigate the problem......»»
States sue to block U.S. rules curbing tailpipe emissions in cars, light trucks
Republican attorneys general from 25 states on Thursday sued the U.S. Environmental Protection Agency to block rules intended to reduce planet-warming emissions from cars and light trucks and encourage electric vehicle manufacturing, arguing the agen.....»»
Tagging project sheds light on the elusive white shark
Researchers have discovered new white shark behaviors by attaching smart tags and cameras to their fins, revealing never-before-seen details of the lives of the elusive creatures......»»
Research reveals a surprising topological reversal in quantum systems
In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both lack a hole—in contrast to.....»»
NASA gives green light to mission to send car-sized drone to Saturn moon
NASA’s Mars helicopter mission is now officially over, but following it is an even more complex flying machine destined to explore Saturn’s largest moon......»»
Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mystery
Coffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in everyday life, it represents.....»»
NASA"s Roman space telescope"s "eyes" pass first vision test
Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA's Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct.....»»
Dual-beamline photoelectron momentum microscopy upgrade advances valence orbital analysis
The world's first dual-beamline photoelectron momentum microscope has been developed at the UVSOR Synchrotron Facility, Japan. This innovative experimental station brings breakthroughs in studying the behavior of electrons in materials governing mate.....»»
How to make Apple Music more private by turning off "Discoverable by Nearby Contacts"
Apple Music has a setting that automatically opts users into sharing your musical tastes with contacts by default. Here's what the problem is, and how to keep what you listen to a bit more private.Apple Music playlistsLike many other streaming servic.....»»
Surrogate otter mom at aquarium is rehabilitating pup "better than any human ever can"
Millie, a fatigued mother of an infant, was ready for a nap. So she grabbed her baby, flipped it around, threw it on her belly and started grooming its tail—a soothing behavior......»»
Light pollution affects coastal ecosystems, too—this underwater "canary" is warning of the impacts
In the early 20th century, canaries were used as early warning systems in coal mines to alert miners to rising levels of carbon monoxide......»»
Coffee grinder, old tires spur creation of sulfur-free oil
Using a coffee grinder, a freezer and a furnace, researchers have discovered a chemical synergy between scrap tires and polystyrene can be harnessed to create sulfur-free, light oil......»»
Fairy-wrens are more likely to help a mate in the harsh of winter, ornithologists find
Monash University ornithologists have shed light on the intricate relationship between social structure, environmental conditions, and cooperative behavior in superb fairy-wrens (Malurus cyaneus)......»»
Sink to source: Does what we put into our plumbing end up back in the water supply?
When you see an advertisement for a detergent promising to brighten your clothes, something called a fluorescent whitening compound, or optical brightener, is probably involved. Such material absorbs UV light and emits visible blue light via fluoresc.....»»
Marine plankton behavior could predict future marine extinctions, study finds
Marine communities migrated to Antarctica during the Earth's warmest period in 66 million years long before a mass-extinction event......»»
Plant sensors could act as an early warning system for farmers
Using a pair of sensors made from carbon nanotubes, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have discovered signals that reveal when plans are experiencing stresses such as heat, light, or attack from i.....»»
Silver-based micromotors that eliminate bacteria can move freely in aqueous media
Researchers at ICIQ in Tarragona have developed a simple technique to produce microscopic crystals that activate in the presence of light, releasing silver ions with antimicrobial activity......»»
Plumbing problem at Glen Canyon Dam brings new threat to Colorado River system
Plumbing problems at the dam holding back the second-largest reservoir in the U.S. are spurring concerns about future water delivery issues to Southwestern states supplied by the Colorado River......»»
Second-biggest black hole in the Milky Way found
May help explain why we see so many of these monsters colliding. Enlarge / The star's orbit, shown here in light, is influenced by the far more massive black hole, indicated by the red orbit. (credit: ESO/L. Calçada) As.....»»
