Children’s toy an ideal modifier for interparticle adhesion and mechanical properties Credit: Tokyo Metropolitan University Tokyo, Japan – Researchers from Tokyo Metropolitan University have studied the properties of mixtures of silicone-coated “magic sand”, a popular kid’s toy, and normal sand. Silicone-coated sand particles were found to interact with each other only, and not with other […]

Load-reducing backpack powers electronics by harvesting energy from walking
Credit: Adapted from ACS Nano 2021, DOI: 10.1021/acsnano.0c07498 Hikers, soldiers and school children all know the burden of a heavy backpack. But now, researchers have developed a prototype that not only makes loads feel about 20% lighter, but also harvests energy from human movements to power small electronics. The new backpack, reported in ACS Nano, […]
Solving complex physics problems at lightning speed
Credit: Illustration: Andreas Ekström and Yen Strandqvist/Chalmers University of Technology A calculation so complex that it takes twenty years to complete on a powerful desktop computer can now be done in one hour on a regular laptop. Physicist Andreas Ekström at Chalmers University of Technology, together with international research colleagues, has designed a new method […]
A professor from RUDN University developed new liquid crystals
Credit: RUDN University A professor from RUDN University together with his Indian colleagues synthesized and studied new dibenzophenazine-based liquid crystals that could potentially be used in optoelectronics and solar panels. The results of the study were published in the Journal of Molecular Liquids. Liquid crystals are an intermediate phase between a liquid and a solid […]
How to train a robot (using AI and supercomputers)
UT Arlington computer scientists use TACC systems to generate synthetic objects for robot training Credit: [William Beksi, UT Arlington] Before he joined the University of Texas at Arlington as an Assistant Professor in the Department of Computer Science and Engineering and founded the Robotic Vision Laboratory there, William Beksi interned at iRobot, the world’s largest […]
Hubble pinpoints supernova blast
Credit: NASA, ESA, and J. Banovetz and D. Milisavljevic (Purdue University) The NASA/ESA Hubble Space Telescope has observed the supernova remnant named 1E 0102.2-7219. Researchers are using Hubble’s imagery of the remnant object to wind back the clock on the expanding remains of this exploded star in the hope of understanding the supernova event that […]
Transition metal ‘cocktail’ helps make brand new superconductors
Concept of high entropy alloys provides a discovery platform for new superconductors Credit: Tokyo Metropolitan University Tokyo, Japan – Researchers from Tokyo Metropolitan University mixed and designed a new, high entropy alloy (HEA) superconductor, using extensive data on simple superconducting substances with a specific crystal structure. HEAs are known to preserve superconducting characteristics up […]
Tiny wireless device sheds light on combating obesity
Texas A&M researchers have designed a device that stimulates the endings of the vagus nerve, which is responsible for the regulation of food intake Credit: Texas A&M University College of Engineering Gastric bypass surgery is sometimes the last resort for those who struggle with obesity or have serious health-related issues due to their weight. Since […]
Entangling electrons with heat
Quantum entanglement is key for next-generation computing and communications technology, Aalto researchers can now produce it using temperature differences Credit: Aalto University A joint group of scientists from Finland, Russia, China and the USA have demonstrated that temperature difference can be used to entangle pairs of electrons in superconducting structures. The experimental discovery, published in […]
Preserving workers’ hearing health by improving earplug efficiency
Work carried out by researchers from ÉTS and the IRSST Credit: ÉTS Noise exposure accounts for 22% of worldwide work-related health problems. Excessive noise not only causes hearing loss and tinnitus, but also increases the risk of cardiovascular diseases. To provide protection, workers normally wear earplugs. However, commonly available earplugs are often uncomfortable, since […]
