A concentrated beam of particles and photons could push us to Proxima Centauri
Getting to Proxima Centauri b will take a lot of new technologies, but there are increasingly exciting reasons to do so. Both public and private efforts have started seriously looking at ways to make it happen, but so far, there has been one signific.....»»
Synthetic fibers and tire abrasion found to have the strongest impact on corals
Corals feed on plankton that they catch from the seawater. Due to the increasing pollution of the oceans, they also ingest tiny plastic particles. Sometimes, the corals are unable to expel the microplastics from their bodies. Instead, they store it i.....»»
Scientists expand search for new particles at the Large Hadron Collider
Since the 1960s, scientists have discovered more than a dozen fundamental particles. They all have fit perfectly into the theoretical framework known as the Standard Model, the best description physicists have of the subatomic world......»»
Amazon hides cheaper items with faster delivery, lawsuit alleges
Hundreds of millions of Amazon's US customers have overpaid, class action says. Enlarge (credit: AdrianHancu | iStock Editorial / Getty Images Plus) Amazon rigged its platform to "routinely" push an overwhelming majority.....»»
An astronomer"s lament: Satellite megaconstellations are ruining space exploration
I used to love rocket launches when I was younger. During every launch, I imagined what it would feel like to be an astronaut sitting in the spacecraft, listening to that final countdown and then feeling multiple gees push me up through the atmospher.....»»
Unlocking quantum precision: Expanded superconducting strips for enhanced photon-counting accuracy
Using single photons as qubits has become a prominent strategy in quantum information technology. Accurately determining the number of photons is crucial in various quantum systems, including quantum computation, quantum communication, and quantum me.....»»
More grizzlies in Idaho? Federal proposal could make it happen as Republicans push delisting
U.S. Fish and Wildlife Service officials have moved forward with plans to consider restoring grizzly bear populations to a part of Idaho where they haven't been seen regularly in decades, all while Idaho's governor and congressional delegation contin.....»»
Neural network assisted high-spatial-resolution polarimetry with non-interleaved chiral metasurfaces
Polarimetry plays a key role in wide applications from remote sensing and astronomy to biology and microscopy. Traditional polarimetry systems are equipped with a set of polarizers, waveplates, beam-splitters or filters, making the systems bulky and.....»»
When nanoplastics are not what they seem: Release of oligomers from polyester textiles
Plastic household items and clothing made of synthetic fibers release microplastics, particles less than five millimeters in size that can enter the environment unnoticed. A small proportion of these particles are so small that they are measured in n.....»»
Beam me up: Using lasers to detect moth migrations
The year is 1941. The British military is installing new-age radar systems to detect German aircraft bound for Great Britain, intent on destruction. Fast forward to 2024. Researchers at North Carolina State University are installing advanced laser-ba.....»»
Apple Watch Ultra with microLED display rumored to have hit another roadblock
For the third year running, the rumor mill is saying that Apple has to push back releasing an Apple Watch Ultra with microLED display another year, this time until 2027.Apple Watch UltraFollowing the first two generations of the Apple Watch Ultra, it.....»»
How does car traffic influence airborne fungal diversity?
Microbial particles including fungi, bacteria, allergens, etc., are common natural components of air. In particular, fungi represent a large portion of the airborne microbes since they are among the most abundant, widely dispersed, and pervasive orga.....»»
How can I get ice off my car? An engineer who studies airborne particles shares quick, easy techniques
If you live somewhere that gets cold in the winter, you've probably seen cars parked outdoors covered in a thin layer of ice on a chilly morning. But what causes this frost, and how can you get rid of it quickly?.....»»
UAW says more than 30% of workers at Hyundai plant in Alabama sign union cards
In November, the UAW said it was launching a first-of-its-kind push to publicly organize the entire non-union auto sector in the U.S. after winning record new contracts with the Detroit 3 automakers......»»
Should you flush with toilet lid up or down? Study says it doesn’t matter
Pardon us while we go stock up on toilet tank disinfectant dispensers. Enlarge / Whether the toilet lid is up or down doesn't make much difference in the spread of airborne bacterial and viral particles. (credit: Peter Dazeley).....»»
New research shows how light propagates in integrated circuits on chips
The field of photonic integrated circuits focuses on the miniaturization of photonic elements and their integration in photonic chips—circuits that carry out a range of calculations using photons, rather than electrons as are used in electronic cir.....»»
A new wavelength of scientific exploration with single-photon detectors
From the minuscule bindings of molecules to the far reaches of space, we're exploring the universe around us by catching sight of the smallest particles of light......»»
Scientists develop antiviral color nanocoating technology
Since the onset of COVID-19, we've become accustomed to seeing antiviral films attached to elevator buttons and public transportation handles. However, conventional antiviral films are made by mixing antiviral metal particles with polymers. Due to th.....»»
DNA particles that mimic viruses hold promise as vaccines
Using a virus-like delivery particle made from DNA, researchers from MIT and the Ragon Institute of MGH, MIT, and Harvard have created a vaccine that can induce a strong antibody response against SARS-CoV-2......»»
Bessel-beam-based side-view measurement of seven-core fiber internal core distribution
Optical fiber, as the basic carrier of modern high-speed and high-capacity communication, is the key to the interconnection of the world. With the rapid development of the communications industry in recent decades, ordinary single-mode optical fiber.....»»
Research reveals quantum entanglement among quarks
Collisions of high energy particles produce "jets" of quarks, anti-quarks, or gluons. Due to the phenomenon called confinement, scientists cannot directly detect quarks. Instead, the quarks from these collisions fragment into many secondary particles.....»»
