Scientists have discovered one of the largest anomalous Hall effects (15,506 siemens per centimeter at 2 Kelvin) ever observed in the new compound, KV3Sb5. This material has a never-before-seen combination of properties: Dirac physics, frustrated magnetism, 2D exfoliatability, and chemical stability. Aside from future fundamental research studying the interplay of these ingredients, the unique...
A breakthrough in fertility science has shattered the universally accepted view of how sperm 'swim'.
A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing -- and potentially exploitable -- conductive properties. University of Texas at Dallas physicists are studying how the ability of twisted bilayer graphene to conduct electrical current changes in response to mid-infrared light.
Scientists have developed a new model that successfully predicted seven of the Sun's biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.
When we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example. High-res imaging shows the cerebellum is 80% of the area of the cortex, indicating it has grown as human behavior and cognition evolved.
When college students learn specific techniques for managing stress and anxiety, their well-being improves across a range of measures and leads to better mental health, a new study finds.
Researchers sought to determine whether a comprehensive and personalized program, designed to mitigate risk factors of Alzheimer's disease could improve cognitive and metabolic function in individuals experiencing cognitive decline. Findings provided evidence that this approach can improve risk factor scores and stabilize cognitive function.
A team has developed a new method of synthesis for three-dimensional nanocarbons, utilizing a catalytic reaction to connect benzene rings and create an eight-membered ring structure. This represents a breakthrough in the synthesis of these nanocarbons, which are expected to be valuable next-generation functional materials.
Miniscule plants growing on desert soils can help drylands retain water and reduce erosion, researchers have found.
Researchers have been able to dial up and down creatures' lifespans by altering the activity of proteins found in roundworm cells that tell them to convert sugar into energy when their cellular energy is running low. Humans also have these proteins, offering up the intriguing possibilities for developing longevity-promoting drugs.
Why is the sea surface temperature of the northern tropics in the summer months often lower than expected? New research shows that a short-term, wind-driven wave phenomenon provides very efficient vertical mixing and cooling of the upper water layer.
Researchers have demonstrated a record setting quantum protocol for sharing a secret amongst many parties.
Tungsten atoms are seen to come together in a way that is similar to an outer space ion. The finding suggests many more types of electron sharing between atoms could exist in nature.
A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like Jupiter.
