The experimental demonstration of topological dissipation in photonic resonators
So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast with dissipative system.....»»
Uganda Ebola outbreak tops 100 cases, 30 deaths; cases growing in capital
Officials say they will test three experimental vaccines in the coming weeks. Enlarge / Red Cross workers don PPE prior to burying a 3-year-old boy suspected of dying from Ebola in 2022 in Mubende, Uganda. (credit: Getty | Luke Dray).....»»
ESA plans for low-orbiting navigation satellites
Satellite navigation is headed closer to users. ESA's Navigation Directorate is planning an in-orbit demonstration with new navigation satellites that will orbit just a few hundred kilometers up in space, supplementing Europe's 23 222-km-distant Gali.....»»
A faster way to find and study topological materials
Topological materials, an exotic class of materials whose surfaces exhibit different electrical or functional properties than their interiors, have been a hot area of research since their experimental realization in 2007—a finding that sparked furt.....»»
A Supersmeller Can Detect the Scent of Parkinson"s, Leading to an Experimental Test for the Illness
This Scottish woman’s hypersensitive nose picked up a chemical signature of Parkinson’s disease that has been used to develop a skin-swab diagnostic.....»»
Researchers Use Quantum "Telepathy" to Win an "Impossible" Game
A new playful demonstration of quantum pseudotelepathy could lead to advances in communication and computation.....»»
Seals have a sense of rhythm
Rhythm is important for human music and speech. But are we the only mammal with a sense of rhythm? In an experimental study published in Biology Letters, a team of researchers led by the Max Planck Institute for Psycholinguistics in Nijmegen and Seal.....»»
Compact and flexible fiber design ensures efficient focusing and razor-sharp images thanks to 3D printing
An interdisciplinary team of researchers from Korea, Australia, Great Britain, and Germany—with participation of Leibniz Institute of Photonic Technology (Leibniz IPHT)—were able for the first time to optimize an optical glass fiber in such a way.....»»
An artificial polariton neuron as a step towards a photonic system that mimics the operation of the human brain
Scientists from the Faculty of Physics at the University of Warsaw and the Polish Academy of Sciences used photons to create a spiking neuron, the basic element of the future photonic neural network processor. The results of their work are published.....»»
These artists found out their work was used to train AI. Now they"re furious
In just months, millions of people have flocked to text-to-image AI systems and they are already being used to create experimental films, magazine covers and images to illustrate news stories. An image generated with an AI system called Midjourney re.....»»
Busting the anti-work myth: Most people actually like their bosses
Do you work for a five-star boss? If quiet quitting—a demonstration of work-to-rule where employees do no more than the minimum work required by their contract—is really a thing, I'd expect more employees to be vocal about disliking their bosses......»»
Topological materials become switchable
A donut is not a breakfast roll. Those are two very clearly distinguishable objects: One has a hole, the other does not. In mathematics, the two shapes are said to be topologically different—you cannot transform one into the other by small, continu.....»»
Twitter rolling out ‘Edit’ button for Blue subscribers, but only if you live in these countries [U: Now in the US]
Earlier this year, Twitter confirmed that it is finally working on the long-awaited “Edit” button. After a brief public demonstration of how this feature will work, Twitter is now rolling out the option to Twitter Blue subscribers to edit tweets.....»»
New cleaning technique boosts electronic and photonic prospects of aluminum nitride
A group of researchers led by Cornell is unlocking the full potential of aluminum nitride—an important material for the advancement of electronics and photonics—thanks to the development of a surface cleaning technique that enables high-quality p.....»»
The Nobel winners who helped prove quantum "spooky action"
Physicists Alain Aspect, John Clauser and Anton Zeilinger developed experimental tools that helped prove quantum entanglement—a phenomenon Albert Einstein famously dismissed as "spooky action at a distance"—is real, paving the way for its use in.....»»
Tesla just shocked everyone with its Optimus robot prototype
Tesla gave an impressive robotics demonstration, proving that the Optimus robot is a serious effort that might change the way work is done in the future......»»
New superconducting qubit testbed benefits quantum information science development
If you've ever tried to carry on a conversation in a noisy room, you'll be able to relate to the scientists and engineers trying to "hear" the signals from experimental quantum computing devices called qubits. These basic units of quantum computers a.....»»
New algorithm could reduce the effects of long-term drift in fiber Bragg-grating temperature sensors
Photonic thermometers—which measure temperature using light—have been around in optical fiber form for decades. These devices, called fiber Bragg gratings, are embedded in commercially available fibers thinner than a human hair, similar to the on.....»»
Spiral dislocation gives 3D topological photonics a robust edge
Crystals have enthralled humans for thousands of years with their visual beauty and elegant symmetrical shapes, and, more recently, with their numerous technological applications. Fundamentally, these materials are based on a highly regular arrangeme.....»»
SNES Star Fox now runs at a silky 60 fps thanks to a new hack
20 fps original is smoothed out without ruining the original pacing. A demonstration of the hacked, 60 fps version of Star Fox released this week (though this demo doesn't get much above 30 fps, as noted in the bottom-left corner). If you.....»»
