Phys.org / Smartphone use cuts into school hours, with social media leading the way
University of California, San Francisco investigators measured smartphone app activity during school hours among US adolescents and reported an average of 1.16 hours of use, with social media apps taking up the most time.
Phys.org / Quantum-enhanced interferometry amplifies detection of tiny laser beam shifts and tilts
A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity.
Phys.org / Study offers possible solution to a gravitational wave mystery
Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave background.
Phys.org / Scientists use string theory to crack the code of natural networks
For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held that nature simply builds ...
Phys.org / The electrifying science behind Martian dust
Mars, often depicted as a barren red planet, is far from lifeless. With its thin atmosphere and dusty surface, it is an energetic and electrically charged environment where dust storms and dust devils continually reshape ...
Phys.org / Unexpected oscillation states in magnetic vortices could enable coupling across different physical systems
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states—so-called Floquet states—in tiny magnetic vortices. Unlike earlier experiments, which required energy-intensive ...
Phys.org / Deformable adjuvants can enhance immune activation in new vaccine design
Conventional vaccine adjuvants primarily rely on molecular binding and biochemical stimulation to activate immune responses, which often leads to limited efficacy in elderly or low-responsive populations. How to introduce ...
Phys.org / Simultaneous packing structures in superionic water may explain ice giant magnetic fields
Superionic water—the hot, black and strangely conductive form of ice that exists in the center of distant planets—was predicted in the 1980s and first recreated in a laboratory in 2018. With each closer look, it continues ...
Phys.org / Scientists solve longstanding mystery about diseases driven by uncontrolled cell growth
For the first time, scientists have answered a longstanding question in cell biology about a partnership of proteins called the "KICSTOR–GATOR1 complex" which operates as a control system inside our cells, telling them ...
Phys.org / Quantum phenomenon enables a nanoscale mirror that can be switched on and off
Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes, but also at the nanometer scale. Recently, physicists at the University of Amsterdam published ...
Phys.org / Sensor lights up to reveal scopolamine, a common substance used for sexual assault
A team from the Universitat Politècnica de València (UPV) has led the development of a new sensor capable of quickly and easily detecting scopolamine, one of the substances most commonly used in crimes of chemical submission, ...
Phys.org / Some dogs can learn new words by eavesdropping on their owners
"Honey, will you take Luna to the P-A-R-K?" Both parents and dog owners know that some words should not be spoken, but only spelled, to prevent small ears from eavesdropping on the conversation. At the age of 1.5 years, toddlers ...
