Ever since the 1986 discovery that copper oxide materials, or cuprates, could carry electrical current with no loss at unexpectedly high temperatures, scientists have been looking for other unconventional superconductors that could operate even closer to room temperature. This would allow for a host of everyday applications that could transform society by making energy … [Read more...] about First study of nickelate’s magnetism finds a strong kinship with cuprate superconductors

In a critical next step toward room-temperature superconductivity at ambient pressure, Paul Chu, Founding Director and Chief Scientist at the Texas Center for Superconductivity at the University of Houston (TcSUH), Liangzi Deng, research assistant professor of physics at TcSUH, and their colleagues at TcSUH conceived and developed a pressure-quench (PQ) technique that retains … [Read more...] about The pressure is off and high temperature superconductivity remains: Development of a new pressure-quench technique demonstrates superconductivity in iron selenide crystals sans pressure

If a virtual world has ever left you feeling nauseous or disorientated, you're familiar with cybersickness, and you're hardly alone. The intensity of virtual reality (VR) -- whether that's standing on the edge of a waterfall in Yosemite or engaging in tank combat with your friends -- creates a stomach-churning challenge for 30-80% of users. In a first-of-its kind study, … [Read more...] about Researchers record brainwaves to measure ‘cybersickness’

Though writing by hand is increasingly being eclipsed by the ease of computers, a new study finds we shouldn't be so quick to throw away the pencils and paper: handwriting helps people learn certain skills surprisingly faster and significantly better than learning the same material through typing or watching videos. "The question out there for parents and educators is why … [Read more...] about Handwriting beats typing and watching videos for learning to read

When you pour cream into a cup of coffee, the viscous liquid seems to lazily disperse throughout the cup. Take a mixing spoon or straw to the cup, though, and the cream and coffee seem to quickly and seamlessly combine into a lighter color and, at least for some, a more enjoyable beverage. The science behind this relatively simple anecdote actually speaks to a larger truth … [Read more...] about Simulations of turbulence’s smallest structures

When gravitational waves were first detected in 2015 by the advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), they sent a ripple through the scientific community, as they confirmed another of Einstein's theories and marked the birth of gravitational wave astronomy. Five years later, numerous gravitational wave sources have been detected, including the first … [Read more...] about Scientists use artificial intelligence to detect gravitational waves

An interdisciplinary team of Cornell and Harvard University researchers developed a machine learning tool to parse quantum matter and make crucial distinctions in the data, an approach that will help scientists unravel the most confounding phenomena in the subatomic realm. The Cornell-led project's paper, "Correlator Convolutional Neural Networks as an Interpretable … [Read more...] about Machine learning tool sorts the nuances of quantum data

Psychologists from UNSW Sydney have developed a new face identification ability test that will help find facial recognition experts for a variety of police and government agencies, including contract tracing. The Glasgow Face Matching Test 2 [GFMT2] targets high-performing facial recognition individuals known as super-recognisers, who have an extraordinary ability to memorise … [Read more...] about Face off for best ID checkers

A new report that could help improve how immersive technologies such as Virtual Reality (VR) and Augmented Reality (AR) are used in healthcare education and training has been published with significant input from the University of Huddersfield. Professor David Peebles, Director of the University's Centre for Cognition and Neuroscience, and Huddersfield PhD graduate Matthew … [Read more...] about New report aims to improve VR use in healthcare education

In the United States, low-income and minority students are completing college at low rates compared to higher-income and majority peers -- a detriment to reducing economic inequality. Double-dose algebra could be a solution, according to a new study published in roceedings of the National Academy of Sciences of the United States of America (PNAS). The paper, "Effects of … [Read more...] about For many students, double-dose algebra leads to college attainment
