University of California - Riverside RIVERSIDE, Calif. — Researchers at the University of California, Riverside, have used a nanoscale synthetic antiferromagnet to control the interaction between magnons — research that could lead to faster and more energy-efficient computers. In ferromagnets, electron spins point in the same direction. To make future computer technologies faster and more energy-efficient, spintronics research employs spin dynamics — fluctuations of the electron spins —...

Climate Change Has Now Invisibly Shifted Earths Axis, New Data Reveal 26 APRIL 2021 Humanitys impacts on our planets climate are so profound, we have for decades been unwittingly shifting the very axis upon which Earth spins around, scientists say. In a new study, researchers examined the phenomenon of polar wandering, in which Earths magnetic north and south poles drift around the surface of the planet, restlessly roaming from the anchored positions of their geographic counterparts.   This ...

Chinese Academy of Sciences The Sun is not as quiet as it seems, and large or small solar activities caused by solar magnetic field occur every moment. Up to now, all measurements related to the solar magnetic field have been polarization measurements. Based on the principle of the Zeeman effect, the magnetic field strength can be simply obtained by measuring the Zeeman splitting of a magnetic sensitive spectral line. However, this is almost inapplicable for visible light and near-infrared spec...

The Missing Submarine Is Feared Lost With All Hands Officials said it would have enough oxygen to last until around just 3 p.m. ET Friday. The missing submarine may be out of air. The Nanggala-402 with crew on the deck. Wikimedia Even military aircraft from the U.S. had joined the search for Indonesias missing KRI Nanggala-402 submarine on Friday, as the hours counted down to 3:00 PM EDT — when Indonesian officials said the vessel would exhaust its oxygen supply. While the search has yet to ...

Chinese Academy of Sciences Supramolecular transformations within coordination-assembled architectures have attracted great attention over the past two decades because fundamental biomolecules are found to be capable of achieving biological functions through conformational changes. Well-controlled interconversion between topologically complex superstructures may lay the foundation for achieving a variety of functions within a switchable system. The size, shape and nature properties between inte...

A Buried Chunk of Alien World Could Be Behind a Weak Spot in Earths Magnetic Field AYLIN WOODWARD, BUSINESS INSIDER Earths suit of geomagnetic armor has a chink, and its growing. A weak spot in our planets magnetic field, located above the southern Atlantic Ocean, has been increasing in size over the last two centuries, and its starting to split in two.   For those of us on the ground, this isnt cause for concern: The protective field continues to shield the planet from deadly solar radiat...

The metamaterial market was valued at USD 305 million in 2021 and is projected to reach USD 1,457 million by 2026. It is expected to grow at a CAGR of 36.7% during the forecast period. The variety in design functional...

Date Time Joyful Screams Perceived More Strongly than Screams of Fear or Anger The human scream signals more than fear of imminent danger or entanglement in social conflicts. Screaming can also express joy or excitement. For the first time, researchers at the University of Zurich have demonstrated that non-alarming screams are even perceived and processed by the brain more efficiently than their alarming counterparts. When a person screams out in pleasure, other people perceive this more strong...
