A four-stroke engine for atoms
If you switch a bit in the memory of a computer and then switch it back again, you have restored the original state. There are only two states that can be called "0 and 1.".....»»
Spin-controlled generation of a complete polarization set with randomly interleaved plasmonic metasurfaces
Optical metasurfaces are finely crafted two-dimensional artificial nanostructures composed of meticulously designed arrays of ultrathin artificial atoms. These surfaces possess capabilities beyond natural materials, enabling multifunctional control o.....»»
Researchers create entangled quantum magnets with protected quantum excitations
When different quantum states combine, new collective states of matter can emerge. In the quantum realm, combining components such as atoms that possess quantum effects can give rise to macroscopic quantum states of matter, featuring exotic quantum e.....»»
Using atomic excitations to measure the rotation of spacetime
How would atoms behave near a supermassive object? We know how atoms behave in extremely weak gravity like that at the Earth's surface: They can be excited from a lower energy level to a higher one when an electron absorbs a photon or a nucleus absor.....»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
First visualization of valence electrons reveals fundamental nature of chemical bonding
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the interactions between atoms are governed by the valence.....»»
Arm-mounted haptics could make future iPhone notifications more discreet
Even silent alerts can be audible if an Apple Watch haptic engine is too powerful, but Apple has plans to make notifications entirely private.Detail from the patent. Notice the armband and possibly an Apple Bracelet tooYou're at a meeting and it's ti.....»»

Rocket engine explodes during test at UK spaceport
A rocket engine exploded during a test launch at Britain's new spaceport in northern Scotland, officials said Tuesday, in a setback for the UK's fledgling space sector......»»
An Apple search engine might happen, but probably won’t
The court ruling that Google is no longer allowed to pay Apple $20B+ a year to be the default search engine raises the question: What now? One potential answer being suggested is that the iPhone maker create its own Apple search engine. But much a.....»»
Ford recalls more than 90,000 police Explorers over engine fire risks
Immediate cause of failures remains unclear; Ford expects to have remedy parts by 2025......»»
Stellantis idles Michigan engine plant for a week
The Trenton Engine Complex, which makes V-6 engines for the Jeep Wrangler and Ram 1500 Classic, is shutting down for a week to balance supply with demand, Stellantis said......»»
Microsoft fixes 6 zero-days under active attack
August 2024 Patch Tuesday is here, and Microsoft has delivered fixes for 90 vulnerabilities, six of which have been exploited in the wild as zero-days, and four are publicly known. The zero-days under attack CVE-2024-38178 is a Scripting Engine Memor.....»»
Research team uses tunable laser to develop straightforward broadband spectroscopy method with Hz-level precision
Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser technology have further enhanced its capabilities. Th.....»»

Apple losing Google’s $20B+ would be just a blip in its Services trajectory
Google has for years made billions of dollars worth of payments to Apple in return for being the default search engine on Apple devices. A court ruling yesterday appears to have declared those payments illegal under antitrust law. But while that w.....»»
Google’s $20B default search deal with Apple violates antitrust law, judge rules
A federal judge today ruled that Google’s deals with Apple and other companies to be the default search engine violated antitrust law. As reported by Bloomberg, Judge Amit Mehta concluded that these agreements reduced competition in the search indu.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Researchers discover graphene flakes in lunar soil sample
A study, published in National Science Review, reveals the existence of naturally formed few-layer graphene, a substance consisting of carbon atoms in a special, thin-layered structure......»»
