Atomically thin van der Waals magnets are widely seen as the ultimately compact media for future magnetic data storage and fast data processing. Controlling the magnetic state of these materials in real-time, however, has proven difficult. But now, an international team of researchers led by Delft University of Technology (TU Delft) has managed to use light in order to change the anisotropy of a van der Waals antiferromagnet on demand, paving the way to new, extremely efficient means of data storage.
The gut and the brain communicate with each other in order to adapt satiety and blood sugar levels during food consumption. The vagus nerve is an important communicator between these two organs.
Prenuptial agreements, or "prenups," can be difficult to talk about. But a recent study offers insights into how people can discuss this often taboo subject. One approach? Use metaphors.
"Many people view prenups as being negative, and argue that they indicate a lack of faith in the marriage from the outset," says Lynsey Romo, corresponding author of the study and an associate professor of communication at North Carolina State University. "By the same token, we know from other research that open communication about financial issues contributes to successful relationships.
RUDN University chemists proposed a new way to synthesize catalysts for the conversion of ethyl alcohol. The obtained materials are promising catalysts for the selective conversion of ethanol, which is an important stage in the development of an alternative technology for obtaining valuable chemical synthesis products based on plant raw materials. The results of the study are published in Catalysis Today.
An international team of astrophysicists led by the Stellar Astrophysics Group of the University of Alicante (UA), the Instituto de Astrofísica de Canarias (IAC), and the University of Valparaíso (Chile) has discovered a massive cluster of stars of intermediate age in the direction of the Scutum constellation. This object, which has been named Valparaíso 1, lies some seven thousand light years away from the Sun, and contains at least fifteen thousand stars.
They studied the extent to which cirrus clouds caused by aircraft occurred during the global hard lockdown between March and May 2020, and compared the values with those during the same period in previous years. The study was led by Johannes Quaas, Professor of Theoretical Meteorology at Leipzig University, and has now been published in the renowned journal "Environmental Research Letters".
The number of specialty behavioral health establishments, their workforce and their wages have increased steadily between 2011 and 2019, according to a new study by Indiana University and University of Michigan researchers.
The largest increases were found in the number of outpatient establishments and the size of their workforce, as well as an increase in the average wage at residential health establishments.
In the universe's earliest moments, particles existed in an unimaginably hot plasma, whose behaviour was governed by deeply complex webs of interaction between individual particles. Today, researchers can recreate these exotic conditions through high-energy collisions between heavy ions, whose products can tell us much about how hot, strongly-interacting matter behaves. Yet without extensive, highly coordinated collaborations between researchers across many different backgrounds, studies like this simply wouldn't be possible.
The myriad processes occurring in biological cells may seem unbelievably complex at first glance. And yet, in principle, they are merely a logical succession of events, and could even be used to form digital circuits. Researchers have now developed a molecular switching circuit made of DNA, which can be used to mechanically alter gels, depending on the pH. DNA-based switching circuits could have applications in soft robotics, say the researchers in their article in Angewandte Chemie.
It's strawberry season in many parts of the U.S, and supermarkets are teeming with these fresh heart-shaped treats. Although the bright red, juicy fruit can grow almost anywhere with lots of sunlight, production in some hot, dry regions is a challenge. Now, researchers reporting in ACS' Journal of Agricultural Food and Chemistry have identified five cultivars that are best suited for this climate, which could help farmers and consumers get the most fragrant, sweetest berries.
Oncotarget published "A high-content AlphaScreen™ identifies E6-specific small molecule inhibitors as potential therapeutics for HPV+ head and neck squamous cell carcinomas" which reported that the incidence of human papillomavirus-positive head and neck squamous cell carcinoma has increased dramatically over the past decades due to an increase in infection of the oral mucosa by
Researchers have demonstrated "giant flexoelectricity" in soft elastomers that could improve robot movement range and make self-powered pacemakers a real possibility. In a paper published this month in the Proceedings of the National Academy of Sciences, scientists from the University of Houston and Air Force Research Laboratory explain how to engineer ostensibly ordinary substances like silicone rubber into an electric powerhouse.
ABERDEEN PROVING GROUND, Md. - A new formula from Army scientists is leading to new insights on how to build an energy-efficient legged teammate for dismounted warfighters.
In a recent peer-reviewed PLOS One paper, the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory's Drs. Alexander Kott, Sean Gart and Jason Pusey offer new insights on building autonomous military robotic legged platforms to operate as efficiently as any other ground mobile systems.
SMU Office of Research & Tech Transfer - Short selling often gets a bad rap because it is a type of trade that bets against the success of a firm. In essence, short selling allows investors to borrow stock from a broker to sell into the market with the hope of buying the stock back at a cheaper price, thus, profiting on the difference between the sell and buy prices. Because of this practice, short selling is sometimes seen as a controversial tactic.
The quantum Hall effect traditionally only plays a role in two-dimensional electron systems. Recently, however, a three-dimensional version of the quantum Hall effect was described in the Dirac semimetal ZrTe5. It has been suggested that this version results from a magnetic field-induced Fermi surface instability that transforms the original three-dimensional electron system into a stack of two-dimensional electron systems.
