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......»»
Stressed rattlesnakes found to calm down in the company of a nearby "friend"
When a creature's stress levels decrease because of the presence of a companion, it is known as social buffering. In highly social animals, such as mammals and birds, this phenomenon is well studied. Now, researchers have examined social buffering in.....»»
How the internal clock of our cells is influenced by mechanical forces
Living organisms possess an internal biological cycle known as the circadian clock, enabling them to adapt to environmental changes arising from the Earth's rotation. This internal clock regulates vital physiological processes including sleep, metabo.....»»
New study reveals abrupt shift in tropical Pacific climate during Little Ice Age
An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years, will shape weather across the planet for the next year or more and give rise to various climatic extremes.....»»
First direct visualization of a zero-field pair density wave
In the field of superconductivity—the phenomenon in which electrons can flow through a material with essentially zero resistance—the "holy grail" of discovery is a superconductor that can perform under everyday temperatures and pressures. Such a.....»»
Mars has liquid guts and strange insides, InSight suggests
Wobbles in its rotation are difficult to explain without a liquid core. Enlarge / Artist's view of what InSight looked like after landing. (credit: NASA/JPL-Caltech) Mars appears to be a frozen expanse of red dust, gapin.....»»
The best shows on Amazon Prime right now (July 2023)
The story of Jack Ryan comes to an end this week with the fourth and final season that will wrap up the thrilling story; a spin-off is in development......»»
Chemists develop new method to create chiral structures
Some molecules exist in two forms, such that their structures and their mirror images are not superimposable, like our left and right hands. Called chirality, it is a property these molecules have due to their asymmetry. Chiral molecules tend to be o.....»»
Surface-enhanced vibrational circular dichroism for chiral mixture sensing
Chiral molecules can present different chemical properties. For applications like drug delivery and diagnosis, it is important to detect chiral signals in mixtures. Although electronic circular dichroism (ECD) spectroscopy has been reported many time.....»»
3D pattern generation via chemical vapor deposition of ceramic eutectic system for novel solid-state phosphors
The eutectic structure of metals and ceramics occurs when multiple solid phases solidify from a liquid phase, forming a three-dimensional (3D) pattern through a self-organizing phenomenon. Traditionally, it was believed that eutectic structures could.....»»
Flow of water on a carbon surface is governed by quantum friction, says study
Water and carbon make a quantum couple: the flow of water on a carbon surface is governed by an unusual phenomenon dubbed quantum friction. A new work published in Nature Nanotechnology experimentally demonstrates this phenomenon—which was predicte.....»»
How climate change fuels extreme heat
Heatwaves across Asia and beyond have already broken records this year, while the arrival of the El Nino climate phenomenon will mean even more extreme temperatures......»»
Direct photons point to positive gluon polarization
A new publication by the PHENIX Collaboration at the Relativistic Heavy Ion Collider (RHIC) provides definitive evidence that gluon "spins" are aligned in the same direction as the spin of the proton they're in. The result, just published in Physical.....»»
The SAT Problem That Everybody Got Wrong
The coin rotation paradox flummoxed SAT test writers even though we encounter this math problem every day.....»»
A new approach to controlling the properties of turbulence
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating it and controlling its pro.....»»
Complexity is a barrier to horizontal gene transfer, shows new study
The recognition of the phenomenon known as horizontal (or lateral) gene transfer (HGT/LGT) revolutionized our understanding of evolutionary mechanisms. Unlike the conventional vertical transmission of genes from parent to offspring, HGT involves the.....»»
Exploring gravity"s effect on quantum spins
A joint research group led by Prof. Sheng Dong and Prof. Lu Zhengtian from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), investigated the coupling effect between neutron spin and gravitational forc.....»»
Researchers demonstrate direct comparison of spin-squeezed optical lattice clocks at record precision level
Although today's best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from the spin statistics of the many atoms they interrogate, known as quantum projection noise (QPN). But by leveragin.....»»
We"ve pumped so much groundwater that we"ve nudged the Earth"s spin, says new study
By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study published in Geophysical R.....»»
Chinese Daigou shoppers represent a new type of entrepreneur
The Chinese practice of Daigou—to "buy on behalf of"—has grown from a seemingly disorganized practice associated with individuals cleaning out supermarkets of baby formula to a multi-billion-dollar phenomenon according to QUT researchers......»»
Quantum interference of light: Anomalous phenomenon found
A counterintuitive facet of the physics of photon interference has been uncovered by three researchers of Université libre de Bruxelles, Belgium. In an article published this month in Nature Photonics, they have proposed a thought experiment that ut.....»»
