Phys.org / AI systems could identify math anxiety from student inputs and change feedback
Math anxiety is a significant challenge for students worldwide. While personalized support is widely recognized as the most effective way to address it, many teachers struggle to deliver this level of support at scale within ...
Phys.org / Supermassive black holes sit in 'eye of their own storms,' studies find
Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists ...
Phys.org / Cosmic radiation brought to light: Researchers measure ionization in dark cloud for the first time
Where starlight doesn't reach, new things are born: For the first time, an international research team has directly measured the effect of cosmic radiation in a cold molecular cloud. The observation shows how charged high-energy ...
Phys.org / Physicists achieve near-zero friction on macroscopic scales
For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led by Quanshui Zheng at ...
Phys.org / Ozone-depleting CFCs detected in historical measurements—20 years earlier than previously known
An international research team led by the University of Bremen has detected chlorofluorocarbons (CFCs) in Earth's atmosphere for the first time in historical measurements from 1951—20 years earlier than previously known. ...
Phys.org / JWST discovers a new extremely metal-poor dwarf galaxy
Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. ...
Phys.org / Solid, iron-rich megastructure under Hawaii slows seismic waves and may drive plume upwelling
Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science Advances, takes a deeper ...
Phys.org / Ultra-thin metasurface can generate and direct quantum entanglement
Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a variety of tasks. An ongoing ...
Phys.org / Did we just see a black hole explode? Physicists think so—and it could explain (almost) everything
In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe capable of producing such ...
Phys.org / How play and social connection may help some dogs understand words
Some dogs are seemingly more talented than others. So-called gifted word learners (GWL) are rare canines that can rapidly learn the names of toys, a skill that most dogs don't possess. To understand why this is so, researchers ...
Phys.org / New mineral sunscreen reduces white cast by using tetrapod-shaped zinc oxide
UCLA researchers have developed a mineral sunscreen formulation that significantly reduces the white, chalky cast that keeps many people from wearing sun protection daily. For decades, dermatologists have urged people to ...
Phys.org / Maps offer neighborhood-level insight into American migration
California's most devastating wildfire—the 2018 Camp Fire, which killed 85 and destroyed nearly 19,000 structures—forced nearly half of all residents living within designated fire perimeters to relocate within a year.
