Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they've found one. In a pair of papers, researchers at the University of Maryland's (UMD) Quantum Materials Center (QMC) and colleagues have shown that uranium ditelluride (or UTe2 for short) displays many of the hallmarks of a topological superconductor … [Read more...] about Unconventional superconductor acts the part of a promising quantum computing platform: If it looks like a duck, swims like a duck and quacks like a duck, then it probably is a duck

A football is not a quantum particle. There are crucial differences between the things we know from everyday life and tiny quantum objects. Quantum phenomena are usually very fragile. To study them, one normally uses only a small number of particles, well shielded from the environment, at the lowest possible temperatures. Through a collaboration between the University of … [Read more...] about Quantum movements of small glass sphere controlled

Electronic circuits that compute and store information contain millions of tiny switches that control the flow of electric current. A deeper understanding of how these tiny switches work could help researchers push the frontiers of modern computing. Now scientists have made the first snapshots of atoms moving inside one of those switches as it turns on and off. Among other … [Read more...] about Scientists take snapshots of ultrafast switching in a quantum electronic device: They discover a short-lived state that could lead to faster and more energy-efficient computing devices

Each fingertip has more than 3,000 touch receptors, which largely respond to pressure. Humans rely heavily on sensation in their fingertips when manipulating an object. The lack of this sensation presents a unique challenge for individuals with upper limb amputations. While there are several high-tech, dexterous prosthetics available today -- they all lack the sensation of … [Read more...] about Liquid metal sensors and AI could help prosthetic hands to ‘feel’: Study first to use liquid metal sensors and machine learning on a prosthetic hand

Many of us swing through gates every day -- points of entry and exit to a space like a garden, park or subway. Electronics have gates too. These control the flow of information from one place to another by means of an electrical signal. Unlike a garden gate, these gates require control of their opening and closing many times faster than the blink of an eye. Scientists at the … [Read more...] about Opening the gate to the next generation of information processing

Sharing ideas in an online learning environment has a distinct advantage over sharing personal details in driving learner engagement in massive open online courses, more commonly known as MOOCs, says new research co-written by a University of Illinois Urbana-Champaign expert who studies the intersection of marketing and digital environments. Online learning engagement can be … [Read more...] about Idea sharing increases online learner engagement

When there is a gas leak in a large building or at an industrial site, human firefighters currently need to go in with gas sensing instruments. Finding the gas leak may take considerable time, while they are risking their lives. Researchers from TU Delft (the Netherlands), University of Barcelona, and Harvard University have now developed the first swarm of tiny -- and hence … [Read more...] about Swarm of autonomous tiny drones can localize gas leaks

More and more companies are using chatbots in customer services. Due to advances in artificial intelligence and natural language processing, chatbots are often indistinguishable from humans when it comes to communication. But should companies let their customers know that they are communicating with machines and not with humans? Researchers at the University of Göttingen … [Read more...] about Trust me, I’m a chatbot

Researchers have found evidence for an anomalous phase of matter that was predicted to exist in the 1960s. Harnessing its properties could pave the way to new technologies able to share information without energy losses. These results are reported in the journal Science Advances. While investigating a quantum material, the researchers from the University of Cambridge who led … [Read more...] about New evidence of an anomalous phase of matter brings energy-efficient technologies closer

The concept of interoperability describes the ability of different systems to communicate. This is a major challenge in biomedical research, and in particular, in the field of personalised medicine, which is largely based on the compilation and analysis of numerous datasets. For instance, the COVID-19 pandemic has shown that even when the technical, legal and ethical … [Read more...] about How to make biomedical research data able to interact?
