In the group of Prof. Karl Leo, physicists, material scientists and engineers are working jointly on the development of novel organic materials and devices for high performance, flexible and possibly even biocompatible electronics and optoelectronics of the future. Increasing the performance of organic devices is one of the key challenges in their research. It was only last year, when the team headed by Dr. Hans Kleemann announced an important breakthrough with the development of efficient, printable vertical organic transistors.
Active or voluntary learning is a major topic in education, psychology, and neuroscience. Over the years, numerous studies have shown that when learning occurs through voluntary action, there is a modulation of attention, motivation and cognitive control that makes the process much more effective. Consequently, memory is benefited. However, although the physiological processes underlying this reality had been identified in the brain of mice, their existence in our species had not been corroborated.
The first observations of a space hurricane have been revealed in Earth's upper atmosphere, confirming their existence and shedding new light on the relationship between planets and space.
Hurricanes in the Earth's low atmosphere are known, but they had never before been detected in the upper atmosphere.
New energy tariffs could leave people on bad deals even worse off despite the potential benefits for everyone, research has found.
The study, led by the University of Leeds, found new types of energy contracts designed for a low carbon future could benefit all types of customer, with opportunities to sell excess energy from solar panels or incentives for using energy at off-peak times.
Advances in wearable devices have enabled e-textiles, which fuse lightweight and comfortable textiles with smart electronics, and are garnering attention as the next-generation wearable technology. In particular, fiber electronic devices endowed with electrical properties, while retaining the specific characteristics of textiles, are key elements in manufacturing e-textiles.
TAMPA, Fla. - Advanced melanoma is one of the deadliest types of cancer, with a 5-year survival rate of only 27% for patients with distant metastases. Recent advances in targeted therapies and immunotherapies have greatly improved patient prognosis; however, many patients eventually develop resistance and disease recurrence. Researchers at Moffitt Cancer Center are investigating how to combine and sequence new therapies to improve survival.
A foundational study conducted by scientists at the National Renewable Energy Laboratory (NREL) shows for the first time that white-rot fungi are able to use carbon captured from lignin as a carbon source.
The research confirms a hypothesis from Davinia Salvachúa Rodriguez, the senior author of a newly published paper. Until now, scientists were unsure whether white-rot fungi--the most efficient lignin-degrading organisms in nature--actually consume the products generated from breaking down lignin.
Inherited retinal dystrophy is a common cause of blindness, with as many as two million people suffering from the disorder globally. No effective treatment is available for retinal dystrophies. Gene therapy is expected to offer a solution, but developing such therapies is possible only when the genetic cause of the disease is known. Related mutations have been identified in more than 70 genes so far, but the genetic background of the disease remains unknown in as many as half of the patients.
NEW YORK, NY--March 2, 2021--In March and April 2020, mental health claim lines for individuals aged 13-18, as a percentage of all medical claim lines, approximately doubled over the same months in the previous year. At the height of the spring wave of the COVID-19 pandemic, this rise in mental health claim lines amounted to 97.0 percent in March and 103.5 percent in April.
Optomechanical microcavities are extremely small structures with diameters of less than 10 micrometers (about a tenth of a human hair) inside which light and mechanical vibrations are confined. Thanks to their small size and to efficient microfabrication techniques that enable them to hold intense light energy and interact with mechanical waves, microcavities can be used as mass and acceleration sensors and in Raman scattering (a spectroscopy technique deployed to analyze materials, including gases, liquids, and solids).
The study gives the first detailed description of a volcanic eruption from Sierra Negra found on Isla Isabela - the largest of the Galápagos Islands and home to nearly 2,000 people.
The findings, published in Nature Communications, reveal how the volcano inflated and fractured before it erupted and captures a new level of detail for any eruption from a volcano on the islands.
Networks of ground-based seismic and GPS monitoring stations, and satellites, captured data for 13 years before Sierra Negra's eruption, in June 2018.
Resveratrol is a plant compound found primarily in red grapes and Japanese knotweed. Its synthetic variant has been approved as a food ingredient in the EU since 2016. At least in cell-based test systems, the substance has anti-inflammatory properties. A recent collaborative study by the Leibniz Institute for Food Systems Biology at the Technical University of Munich and the Institute of Physiological Chemistry at the University of Vienna has now shown that the bitter receptor TAS2R50 is involved in this effect.
CHICAGO, March 2, 2021 -- More than 70 percent of dentists surveyed by the American Dental Association (ADA) Health Policy Institute are seeing an increase of patients experiencing teeth grinding and clenching, conditions often associated with stress. This is an increase from ADA data released in the fall that showed just under 60 percent of dentists had seen an increase among their patients.
The amount of green space surrounding children's homes could be important for their risk of developing ADHD. This is shown by new research results from iPSYCH.
A team of researchers from Aarhus University has studied how green space around the residence affects the risk of children and adolescents being diagnosed with ADHD. And the researchers find an association.
Anorexia nervosa, bulimia nervosa and binge-eating disorder are the three main eating disorders that 4 out of in 10 individuals living in Western Europe will experience at some point in their lives. In recent years, studies on the genetic basis of anorexia nervosa have highlighted the existence of predisposing genetic markers, which are shared with other psychiatric disorders.
