Researchers from Basel, Bochum and Copenhagen have gained new insights into the energy states of quantum dots. They are semiconductor nanostructures and promising building blocks for quantum communication. With their experiments, the scientists confirmed certain energy transitions in quantum dots that had previously only been predicted theoretically: the so-called radiative Auger process. For their investigations, […] More
One way that scientists seek to bring to Earth the fusion process that powers the sun and stars is trapping hot, charged plasma gas within a twisting magnetic coil device shaped like a breakfast cruller. But the device, called a stellarator, must be precisely engineered to prevent heat from escaping the plasma core where it […] More
As scientists work to determine why some of the latest climate models suggest the future could be warmer than previously thought, a new study indicates the reason is likely related to challenges simulating the formation and evolution of clouds. The new research, published in Science Advances, gives an overview of 39 updated models that are […] More
The rapid politicization of the COVID-19 pandemic can be seen in messages members of the U.S. Congress sent about the issue on the social media site Twitter, a new analysis found. Using artificial intelligence and resources from the Ohio Supercomputer Center, researchers conducted an analysis that covered all 30,887 tweets that members sent about COVID-19 […] More
A team at Bristol has challenged the idea that touchscreens are limited to 2D and rectangular shapes by developing an interactive display that can be sprayed in any shape. Inspired by the way an artist creates graffiti on a wall and using a novel combination of sprayable electronics and 3D printing, the technique, called ProtoSpray, […] More
Artificial intelligence (AI) is an important innovation in diagnostics, because it can quickly learn to recognize abnormalities that a doctor would also label as a disease. But the way that these systems work is often opaque, and doctors do have a better “overall picture” when they make the diagnosis. In a new publication, researchers from […] More
Cyberbullying — bullying online rather than face to face — is linked to various types of post traumatic stress disorder (PTSD) symptoms, both for victims and perpetrators, suggests the first study of its kind, published online in the Archives of Disease in Childhood. Their findings prompt the researchers to suggest that asking about cyberbullying should […] More
A University of Texas at Dallas study of 100 mobile apps for kids found that 72 violated a federal law aimed at protecting children’s online privacy. Dr. Kanad Basu, assistant professor of electrical and computer engineering in the Erik Jonsson School of Engineering and Computer Science and lead author of the study, along with colleagues […] More
