Spintronics is an emerging area of research that aims to develop devices that transmit, process and store information leveraging the intrinsic angular momentum of electrons, known as spin. A key objective of spintronics studies is to identify strategies to use magnetic insulators to achieve the transport of signals over long distances.

The interstellar medium and combustion systems contain polycyclic aromatic hydrocarbons (PAHs) as fundamental molecular building blocks that form fullerenes and carbonaceous nanostructures. However, researchers have yet to investigate and understand aromatic molecules carrying five-membered rings that form the essential building blocks of nonplanar polycyclic aromatic hydrocarbons (PAHs), which eventually lead to the formation of interstellar grains or carbonaceous cosmic dust. In a new report now published in Science Advances... Читать дальше...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an interesting extrasolar planetary system consisting of a K-dwarf host star, a Jupiter-sized planet and a white dwarf. The finding and parameters of the system, designated TOI-1259, were presented in a paper published January 7 on the arXiv pre-print repository.

A team of researchers affiliated with several institutions in China has used drones to create a prototype of a small airborne quantum network. In their paper published in the journal Physical Review Letters, the researchers describe sending entangled particles from one drone to another and from a drone to the ground.

University of Virginia Darden School of Business professor Anthony Palomba is an expert in media management, an interdisciplinary academic discipline that examines how audiences consume media and entertainment products and services, as well as how entertainment companies compete amid shifting consumer preferences.

NUS physicists have developed a method to induce the transition of a rare-earth nickelate from their native perovskite form to infinite-layer structures. This allowed them to build a complete phase diagram of this nickelate superconductor.

Gentoo penguins are benefiting from a newly enlarged no-fishing zone (known as a No-Take Zone NTZ) around the sub-Antarctic island of South Georgia following British Antarctic Survey (BAS) tracking research commissioned by the RSPB.

Muscle structure and body size predict the athletic performance of Olympic athletes, such as sprinters. The same, it appears, is true of wild seabirds that can commute hundreds of kilometers a day to find food, according to a recent paper by scientists from McGill and Colgate universities published in the Journal of Experimental Biology.

In addition to containing many firsts, new research from the University of Otago's Centre for Irish and Scottish Studies provides comprehensive insights into the identity of Irish people in Aotearoa New Zealand.

Over the past century, global sea level has been rising at an increasingly rapid pace. That means the damage done by storm surges will be more severe, coastal erosion will accelerate and flooding will become more frequent and more expensive.

Two giant radio galaxies have been discovered with South Africa's powerful MeerKAT telescope. These galaxies are thought to be amongst the largest single objects in the Universe. The discovery has been published today in Monthly Notices of the Royal Astronomical Society .

How cells respond in the face of stress is a critical component of maintaining homeostasis and preventing disease, but its mechanisms are poorly understood. New research out of the University of Chicago has fit together another piece of the puzzle by identifying a key protein, Sis1, involved in the rapid activation of the heat shock response, which allows cells to respond in the face of temperature changes that can lead to misfolded proteins. This has implications for conditions where changes in... Читать дальше...

Habitat destruction by logging and agriculture is pushing parrot species towards extinction, while current protected areas are failing to mitigate these effects, according to new research.

Glasses have a liquid-like disordered structure but solid-like mechanical properties. This leads to one of the central mysteries of glasses: Why don't they flow like liquids? This question is so important that it was selected by the journal Science in 2005 as one of 125 key, unanswered scientific questions, and one of 11 unsolved important physical issues.

LGBTQ professionals' pride in their science, technology, engineering, and math work is not reciprocated, say researchers.

Why is studying spin properties of one-dimensional quantum nanowires important?

After an injury to the spinal cord, patients often remain paralyzed because damaged nerve tracts do not regrow due to the formation of scar tissue. Scientists from the Max Planck Institute for the Science of Light in Erlangen, together with colleagues from Dresden and Athens, have now been able to identify important cells and molecules in the scar, using zebrafishes as a model organism.

NASA's images of the sun's dynamic and dazzling beauty have captivated the attention of millions. In 2021, the US Postal Service is showcasing the sun's many faces with a series of sun Science forever stamps that show images of solar activity captured by NASA's Solar Dynamics Observatory, or SDO.

Durable, high-performing perovskite solar cells also require durable, high-performing charge-transporting layers. Scientists have developed the first organic hole transporter that does not need a dopant to attain high charge mobility and stability. According to the study published in the journal Angewandte Chemie, this novel hole-transporting layer outperforms reference materials and protects the perovskite organic cell from air humidity.

Researchers from Tokyo Metropolitan University have discovered that fruit flies with genetic modifications to enhance glucose uptake have significantly longer lifespans. Looking at the brain cells of aging flies, they found that better glucose uptake compensates for age-related deterioration in motor functions, and led to longer life. The effect was more pronounced when coupled with dietary restrictions. This suggests healthier eating plus improved glucose uptake in the brain might lead to enhanced lifespans.
