Result draws on 50-year-old theorem from quantum field theory to make entanglement measurement more efficient.
Liquid crystal is a state of matter that exhibits properties of both liquid and solid. It can flow like a liquid, while its constituent molecules are aligned as in a solid. Liquid crystal is widely used nowadays, for example, as a core element of LCD devices.
The magnetic analog of this kind of material is dubbed the “spin-nematic phase,” where spin moments play the role of the molecules. However, it has not yet been directly observed despite its prediction a half-century ago. The main challenge stems from the fact that most conventional experimental techniques are insensitive to spin quadrupoles, which are the defining features of this spin-nematic phase.
But now, for the first time in the world, a team of researchers led by Professor Kim Bumjoon at the IBS Center for Artificial Low-Dimensional Electronic Systems in South Korea has succeeded at directly observing spin quadrupoles. This work was made possible through remarkable achievements over the last decades in synchrotron facility development.
Personal growth and success require a focus on emotional intelligence, individualized practices, and a shift away from material desires and instant gratification.

Berkshire Hathaway said on Tuesday it has shed its holdings in General Motors and Procter & Gamble, and trimmed its stake in Amazon.com, as the conglomerate controlled by billionaire Warren Buffett boosted its cash pile to a record $157.2 billion.
In a regulatory filing detailing its U.S.-listed stock holdings as of Sept. 30, Berkshire reported no holdings in GM and P&G, after reporting stakes of $848 million and $48 million in June, and said it reduced its stake in Amazon by 5%.
Berkshire also appeared to have shed what had been a $621 million stake in Celanese, a specialty materials company.
Researchers question whether an AI-controlled lab assistant actually made any novel substances.
Ferroicity and multiferroicity
Ferroic materials are those that exhibit a spontaneous ordering of their electric, magnetic or structural properties. The best-known example of ferroicity is ferromagnetism, in which the magnetic moments of a material all point in one direction, but other types of ferroic ordering are possible. In ferroelectricity, for example, it is the electric polarization that spontaneously orders itself, while ferroelastic materials display spontaneous strain.
Multiferroicity occurs when several properties of a material have their own individual preferred states. For example, a magnetic multiferroic material might have magnetic moments that point in one direction, and electric charge that also shifts in a certain direction. Importantly, the two phenomena are independent of each other.
Results of study from Ryugu samples.
Micrometeorites originating from icy celestial bodies in the outer Solar System may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system. That discovery was published today in Nature Astronomy by an international team of researchers, including University of Hawai’i at Manoa scientists, led by Kyoto University.
Nitrogen compounds, such as ammonium salts, are abundant in material born in regions far from the sun, but evidence of their transport to Earth’s orbital region had been poorly understood.
Tesla’s new Cybertruck launch and next generation vehicle will be game-changing, with innovations in materials, manufacturing processes, and affordability.

When electricity flows through a battery, the materials inside it gradually wear down. The physical forces of stress and strain also play a role in this process, but their exact effects on the battery’s performance and lifespan are not completely known.
A team led by researchers at the Department of Energy’s Oak Ridge National Laboratory developed a framework for designing solid-state batteries, or SSBs, with mechanics in mind. Their paper, published in Science, reviewed how these factors change SSBs during their cycling.
A single strand of fiber developed at Washington State University has the flexibility of cotton and the electric conductivity of a polymer, called polyaniline.
The newly developed material showed good potential for wearable e-textiles. The WSU researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas, detailing their findings in the journal Carbohydrate Polymers.
“We have one fiber in two sections: one section is the conventional cotton: flexible and strong enough for everyday use, and the other side is the conductive material,” said Hang Liu, WSU textile researcher and the study’s corresponding author. “The cotton can support the conductive material which can provide the needed function.”
