A new spintronic phenomenon: Chiral-spin rotation found in non-collinear antiferromagnet
Researchers at Tohoku University and the Japan Atomic Energy Agency (JAEA) have discovered a new spintronic phenomenon—a persistent rotation of chiral-spin structure......»»
A new way to identify chiral molecules with light could vastly improve detection efficiency
Chiral molecules are those that have two versions that are mirror images, like our right and left hands. These molecules have the same structure but different properties when they interact with other molecules, including those inside our bodies. This.....»»
Mars keeps spinning faster every year, NASA InSight data says
Radio signals from the lander help us track Mars' spin as it slowly shifts. Enlarge / A self portrait of InSight's hardware on the red planet. (credit: NASA/JPL-Caltech) To say Mars is a bizarre planet might be something.....»»
How El Nino could impact health, food and the economy
The El Niño weather phenomenon is just warming up, according to scientists, potentially paving the way for higher temperatures and extreme weather events in a year that has already seen plenty of both......»»
The Last Voyage of the Demeter review: Dracula by way of Alien
Adapting just a few pages of Bram Stoker's novel, The Last Voyage of the Demeter puts an entertaining new spin on the most famous vampire of them all, Dracula......»»
Biologists find what colors a butterfly"s world
As butterflies flit among flowers, they don't all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. University of California,.....»»
Model with an extraordinary glass-forming ability expected to approach the ideal glass state, if it exists
Humans have been entranced by the unique beauty and physical properties of glass, producing jewelry, containers, and tools from the material for millennia. However, the physics underlying the phenomenon of glass formation remains surprisingly complex.....»»
NASA InSight study finds Mars is spinning faster
Scientists have made the most precise measurements ever of Mars's rotation, for the first time detecting how the planet wobbles due to the "sloshing" of its molten metal core. The findings, detailed in a recent Nature paper, rely on data from NASA's.....»»
Scientists observe first evidence of "quantum superchemistry" in the laboratory
A team from the University of Chicago has announced the first evidence for "quantum superchemistry"—a phenomenon where particles in the same quantum state undergo collective accelerated reactions. The effect had been predicted, but never observed i.....»»
Florida corals in hotter water than first thought. Scientists blame "weird phenomenon"
Entire reefs in the Florida Keys are ghost towns, victims of an unseasonably early and severe marine heat wave that likely won't end anytime soon that's already bleached and killed thousands of corals......»»
Unveiling the anomalous dynamics of non-collinear antiferromagnets
Researchers at Tohoku University and Massachusetts Institute of Technology (MIT) have unveiled a representative effect of the anomalous dynamics at play when an electric current is applied to a new class of magnetic materials called non-collinear ant.....»»
Cyclist takes watchOS 10’s Bluetooth bike accessory support on Apple Watch for a spin
Apple packed watchOS 9 with advanced run tracking features for runners. watchOS 10 brings that same level of emphasis to cycling workouts on Apple Watch. more….....»»
Disney reportedly wants to team up with Apple to expand ESPN distribution
While Bob Iger has said that Disney doesn’t currently plan to spin ESPN off, the company is actively looking for “strategic partners” that could help with things like distribution and content. A new report from the New York Post this week says.....»»
Improving wildfire predictions with Earth-scale climate models
Wildfires have shaped the environment for millennia, but they are increasing in frequency, range and intensity in response to a hotter climate. The phenomenon is being incorporated into high-resolution simulations of the Earth's climate by scientists.....»»
Millimeter-scale meron lattices that can serve as spin injectors for LEDs
Merons, topological structures based on in-plane magnetized magnetic materials, could have numerous valuable applications, particularly for carrying information or storing magnetic charge. Most past realizations of these structures, however, were lim.....»»
Acer Chromebook Spin 714 review: A sub-$700 laptop with great battery life
The Acer Chromebook Spin 714 has above-average battery life, a decent keyboard, a stylish chassis, a 1440p webcam — all for under $700. What’s not to love?.....»»
Study reveals how delayed Antarctic melt season reduces albedo feedback
The ice-covered continent of Antarctica is not free from climate change. On the contrary, a rise in temperatures at high latitudes is much stronger than that in global mean temperatures, a phenomenon known as the polar amplification effect......»»
Study reveals structures of six states of a rotary sodium ion pump
Six structures exhibited by the rotating sodium ion pump were reconstructed in 3D using cryo-electron microscopy. This analysis revealed that the rotor exhibits non-uniform rotation behavior due to partial structural interference with the stator comp.....»»
Some alloys don"t change size when heated, and we now know why
Nearly every material, whether it is solid, liquid, or gas, expands when its temperature goes up and contracts when its temperature goes down. This property, called thermal expansion, makes a hot air balloon float, and the phenomenon has been harness.....»»
On-chip infrared circular polarization detector with ultrahigh discrimination
Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ellipticity) detection is essential for chiral mole.....»»
New study reveals remarkable impact of intrinsic spin shielding in platinum-rare earth alloys on electrocatalysis
The oxygen reduction reaction is a crucial step in the performance of fuel cells, determining their efficiency and overall applicability. However, sluggish kinetics in the ORR, particularly at the cathode, pose challenges due to its slow and energy-i.....»»
