Catalysts are indispensable for many technologies. To further improve heterogeneous catalysts, it is required to analyze the complex processes on their surfaces, where the active sites are located. Scientists of Karlsruhe Institute of Technology (KIT), together with colleagues from Spain and Argentina, have now reached decisive progress: As reported in Physical Review Letters, … [Read more...] about Catalyst research: Molecular probes require highly precise calculations

A smart ring that generates continuous temperature data may foreshadow COVID-19, even in cases when infection is not suspected. The device, which may be a better illness indicator than a thermometer, could lead to earlier isolation and testing, curbing the spread of infectious diseases, according to a preliminary study led by UC San Francisco and UC San Diego. An analysis of … [Read more...] about Wearable sensor may signal you’re developing COVID-19 — even if your symptoms are subtle: Smart ring may flag early illnesses, study shows

Researchers in Japan and Italy are embracing chaos and nonlinear physics to create insectlike gaits for tiny robots -- complete with a locomotion controller to provide a brain-machine interface. Biology and physics are permeated by universal phenomena fundamentally grounded in nonlinear physics, and it inspired the researchers' work. In the journal Chaos, from AIP Publishing, … [Read more...] about ‘Chaotic’ way to create insectlike gaits for robots: By using small networks of Rössler systems, a locomotion controller enables a brain-machine interface for a six-legged antlike robot.

A team of researchers from the Technical University of Munich, the Walther-Meissner-Institute of the Bavarian Academy of Sciences and Humanities, and the Norwegian University of Science and Technology in Trondheim has discovered an exciting method for controlling spin carried by quantized spin wave excitations in antiferromagnetic insulators. Elementary particles carry an … [Read more...] about Information transport in antiferromagnets via pseudospin-magnons

In the transition toward clean, renewable energy, there will still be a need for conventional power sources, like coal and natural gas, to ensure steady power to the grid. Researchers across the world are using unique materials and methods that will make those conventional power sources cleaner through carbon capture technology. Creating accurate, detailed models is key to … [Read more...] about Carbon capture’s next top model: Research analyzes modeling techniques for carbon capture technology

Getting computers to "think" like humans is the holy grail of artificial intelligence, but human brains turn out to be tough acts to follow. The human brain is a master of applying previously learned knowledge to new situations and constantly refining what's been learned. This ability to be adaptive has been hard to replicate in machines. Now, Salk researchers have used a … [Read more...] about Teaching artificial intelligence to adapt: Simulated system could help develop better artificial intelligence, treatments for brain disorders

The spread of the Internet is shaping migration in profound ways. A McGill-led study of over 150 countries links Internet penetration with migration intentions and behaviours, suggesting that digital connectivity plays a key role in migration decisions and actively supports the migration process. Countries with higher proportions of Internet users tend to have more people who … [Read more...] about How the spread of the internet is changing migration: Team of international researchers trace digital steps along the migration path

Is it possible to read a person's mind by analyzing the electric signals from the brain? The answer may be much more complex than most people think. Purdue University researchers -- working at the intersection of artificial intelligence and neuroscience -- say a prominent dataset used to try to answer this question is confounded, and therefore many eye-popping findings that … [Read more...] about Researchers uncover blind spots at the intersection of AI and neuroscience: Findings debunk dozens of prominent published papers claiming to read minds with EEG

Methods currently used around the world for predicting the development of COVID-19 and other pandemics fail to report precisely on the best and worst case scenarios. Newly developed prediction method for epidemics, published in Nature Physics, solve this problem. "It is about understanding best and worst-case scenarios -- and the fact that worst case is one of the most … [Read more...] about New approach can improve COVID-19 predictions worldwide

Scientists often look to nature for cues when designing robots -- some robots mimic human hands while others simulate the actions of octopus arms or inchworms. Now, researchers in the University of Georgia College of Engineering have designed a new soft robotic gripper that draws inspiration from an unusual source: pole beans. While pole beans and other twining plants use their … [Read more...] about Engineers develop soft robotic gripper: Inspired by twining plants, it has a variety of possible applications
