Novel way to manipulate exotic materials

Finding could revolutionize electronics, quantum computing

2023-06-20

(Press-News.org) An advance in a topological insulator material — whose interior behaves like an electrical insulator but whose surface behaves like a conductor — could revolutionize the fields of next-generation electronics and quantum computing, according to scientists at Oak Ridge National Laboratory.

Discovered in the 1980s, a topological material is a new phase of material whose discoverers received a Nobel Prize in 2016. Using only an electric field, ORNL researchers have transformed a normal insulator into a magnetic topological insulator. This exotic material allows electricity to flow across its surface and edges with no energy dissipation. The electric field induces a change in the state of matter.

“The research could result in many practical applications, such as next-generation electronics, spintronics and quantum computing,” said ORNL’s Mina Yoon, who led the study.

Such matter could lead to high-speed, low-power electronics that burn less energy and operate faster than current silicon-based electronics. The ORNL scientists published their findings in 2D Materials. — Lawrence Bernard

Research pilot sets the stage for better, more equitable aortic stenosis care

2023-06-20

DALLAS, June 20, 2023 — New research published today in Circulation: Cardiovascular Quality and Outcomes examines the pilot phase of the American Heart Association quality improvement program Target: Aortic Stenosis™. The program aims to lay the groundwork to more reliably measure performance on the quality of aortic stenosis (AS) care from diagnosis to treatment. The Target: Aortic Stenosis program focuses on closing care gaps for patients who are not appropriately diagnosed and referred for initial ...

Community spaces may promote healthy aging for rural Black, Hispanic adults

2023-06-20

UNIVERSITY PARK, Pa. — Millions of Americans over the age of 65 lack access to the social and emotional support they need for healthy aging, according to the Centers for Disease Control and Prevention. Non-white individuals in rural communities are especially susceptible. New research from Penn State found that the presence of social infrastructure — shared community spaces that are free or low cost to visit — in rural communities may help provide social and emotional support and promote healthy aging among older, ...

Concluding remarks & perspectives of Targeting Phage Therapy 2023

2023-06-20

The 6th World Congress on Targeting Phage Therapy 2023 that was held on June 1-2 in Paris, and gathered more than 150 attendees from 30+ different countries. Targeting Phage Therapy 2023 included more than 71 presentations between major talks, short orals, and posters. The Chairman of the scientific committee Dr. Marvin Edeas Université de Paris, Cochin Institute, France, and Dr. Domenico Frezza, University of Roma Tor Vergata, Italy, stated: “It’s wonderful to hear that the speakers at the Targeting Phage Therapy 2023 conference delivered excellent presentations on a variety of fantastic topics. The fact ...

Scientists unearth 20 million years of ‘hot spot’ magmatism under Cocos plate

2023-06-20

Ten years ago, Samer Naif made an unexpected discovery in Earth’s mantle: a narrow pocket, proposed to be filled with magma, hidden some 60 kilometers beneath the seafloor of the Cocos Plate. Mantle melts are buoyant and typically float toward the surface — think underwater volcanoes that erupt to form strings of islands. But Naif’s imaging instead showed a clear slice of semi-molten rock: low-degree partial melts, still sandwiched at the base of the plate some 37 miles beneath the ocean floor. Then, the observation provided an explanation for how tectonic plates can gradually slide, ...

When it comes to COVID-19, belly fat upsets the apple cart

2023-06-20

Researchers from Tokyo Medical and Dental University (TMDU) find that apple-shaped obesity is associated with cytokine storm and a higher risk of death in COVID-19 patients Tokyo, Japan – Eating an apple a day may keep the doctor away, but having an apple shape is not nearly as healthy. Now, researchers from Japan have shown that people who carry their weight in their bellies may be at greater risk of poor outcomes if they catch COVID-19. In a study published last month in Proceedings of the National Academy of Sciences (PNAS), researchers from Tokyo Medical ...

Company culture shapes willingness of workers to act sustainably, research shows

2023-06-20

Amidst rising concerns about the global climate crisis, Princeton researchers have uncovered the surprisingly large role that companies play in shaping sustainable behaviors among employees, as well as a link between eco-friendly behaviors and happier workers. In research published in Current Research in Ecological and Social Psychology, the Princeton team reported the results from a nationwide study of employees to understand the factors that influence whether workers take sustainable actions and incorporate the environment into their day-to-day decision making. The results ...

USF Health researchers show how the placenta protects fetus in the womb against viral infections

2023-06-20

Give credit to your dad’s gene for keeping you safe during those long months in your mother’s womb. Because without this genetic warrior, you might have succumbed to any number of viral infections that otherwise could be fatal to a fetus. A new paper published this week in the journal Cell Host & Microbe explains the mechanisms behind this anti-viral protection. “What’s unique about this gene is how it produces a form of defense for the baby in the womb,’’ said Hana Totary-Jain, PhD., associate professor of Molecular ...

Outcome indicators make quality of life after childhood cancer measurable

2023-06-20

Outcome indicators make quality of life after childhood cancer measurable A new measurement tool helps analyzing the survival rate of children with cancer, but also the quality of survival. Researchers at the Princess Máxima Center for Pediatric Oncology have worked with patients and survivors to develop a set of outcome indicators that measure health issues. By making the balance between survival and quality of life measurable, the outcome indicators help improve care for children with cancer. There are many types of childhood cancer, and the consequences ...
