Boron nitride is a technologically interesting material because it is very compatible with other two-dimensional crystalline structures. It therefore opens up pathways to artificial heterostructures or electronic devices built on them with fundamentally new properties.
About a year ago, a team from the Institute of Physics at Julius-Maximilians-Universität (JMU) Wuerzburg in Bavaria, Germany, succeeded in creating spin defects, also known as qubits, in a layered crystal of boron nitride and identifying them experimentally.
New York, NY--April 6, 2021--The digital revolution is built on a foundation of invisible 1s and 0s called bits. As decades pass, and more and more of the world's information and knowledge morph into streams of 1s and 0s, the notion that computers prefer to "speak" in binary numbers is rarely questioned. According to new research from Columbia Engineering, this could be about to change.
The global movement of goods and people, in its modern form, has many unwanted side effects. One of these is that animal and plant species travel around the world with it. Often they fail to establish themselves in the ecosystems of the destination areas. Sometimes, however, due to a lack of effective management, they multiply to such an extent in the new environment that they become a threat to the entire ecosystem and economy. Thousands of alien species are currently documented worldwide. A quarter of them are in highly vulnerable, aquatic habitats.
LAWRENCE -- An international trade law expert at the University of Kansas argues in a pair of new articles that human rights and trade are now inextricably linked, as evidenced by U.S. and international reactions to actions in China, and asserts that approach is an appropriate use of trade.
Ann Arbor, April 6, 2021 - New data from the Centers for Disease Control and Prevention (CDC) show that one in four adults with HIV in the United States has experienced intimate partner violence (IPV), which disproportionately affects women and LGBT populations. Further, people with HIV who experienced IPV in the past 12 months were more likely to engage in behaviors associated with elevated HIV transmission risk, were less likely to be engaged in routine HIV care and more likely to seek emergency care services and have poor HIV clinical outcomes.
Sea urchins receive a lot of attention in California. Red urchins support a thriving fishery, while their purple cousins are often blamed for mowing down kelp forests to create urchin barrens. Yet for all the notice we pay them, we know surprisingly little about the microbiomes that support these spiny species.
Philadelphia, April 6, 2021 - Since the discovery of leptin in the 1990s, researchers have wondered, how does leptin, a hormone made by body fat, suppress appetite? Despite tremendous gains in the intervening three decades, many questions still remain. Now, a new study in mice describes novel neurocircuitry between midbrain structures that control feeding behaviors that are under modulatory control by leptin.
Biophysicists from Ludwig-Maximilians-Universitaet (LMU) in Munich have shown that a phenomenon known as diffusiophoresis, which can lead to a directed particle transport, can occur in biological systems.
As part of an international collaboration, researchers from ELTE Eötvös Loránd University developed a new animal model to study a rare genetic disease that can lead to blindness at the age of 40-50. The new model could open up new perspectives in our understanding of this metabolic disease and will also help to identify new potential drug candidates, according to the recent study published in Frontiers in Cell and Developmental Biology.
The universe is expanding at an ever-increasing rate, and while no one is sure why, researchers with the Dark Energy Survey (DES) at least had a strategy for figuring it out: They would combine measurements of the distribution of matter, galaxies and galaxy clusters to better understand what's going on.
During the early phase of the pandemic, approximately 40% of the COVID-19 literature was shared as preprints - freely available manuscripts that are shared prior to peer-review.
A new large-scale study led by UC Davis Health and UC San Francisco researchers assessed the risks of leukemia in children with Down syndrome. It pointed to stronger than expected associations between Down syndrome and acute myeloid leukemia (AML), one type of blood cancer.
Tweets about Russia by Donald Trump during his presidency caused short but noticeable depreciations of the rouble. Meanwhile, the introduction of new sanctions, upon which the president did not comment, had no such effect. This was the finding of a group of researchers, which included Elena Fedorova, Professor of the Faculty of Economic Sciences of HSE University.
"On a scale of one to 10, how much pain are you in?"
In a recent study published by the Journal of Pain, co-authored by Elizabeth Losin, assistant professor of psychology and director of the Social and Cultural Neuroscience lab at the University of Miami, researchers found that a patient's pain responses may be perceived differently by others based on their gender.
