Phys.org / Social media use soars as kids drop sports, reading and the arts
In striking new statistics, experts warn of social media's growing grip on young people, with use among children and teens soaring by more than 200% since before COVID and showing no sign of decline.
Phys.org / How most of the universe's visible mass is generated: Experiments explore emergence of hadron mass
Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, nature's fundamental building blocks bound together by gluons, their masses are much larger than the ...
Phys.org / Disputed Jordan codices reveal age variations under ion-beam scrutiny
Scientists have delivered the most detailed assessment yet of a set of disputed lead books known as the Jordan codices. With debate centered on whether they could date back to the early Christian period, a study led by the ...
Phys.org / Enzyme-free approach gently detaches cells from culture surfaces
Anchorage-dependent cells are cells that require physical attachment to a solid surface, such as a culture dish, to survive, grow, and reproduce. In the biomedical industry, and others, having the ability to culture these ...
Phys.org / Stars forge elements in new, uncharted ways: Experimental physicist discusses the 'i-process'
All around us are elements forged in stars, from the nickel and copper in coins to the gold and silver in jewelry. Scientists have a good understanding of how these elements form: In many cases, a nucleus heavier than iron ...
Phys.org / New cable design mitigates flaws in superconducting wires
When current flows through a wire, it doesn't always have a perfect path. Tiny defects within the wire mean current must travel a more circuitous route, a problem for engineers and manufacturers seeking reliable equipment.
Phys.org / Wine grape still carries molecular memory of its ancestry after 400 years, study finds
About 400 years ago, a cross between cabernet franc and sauvignon blanc gave birth to cabernet sauvignon. Today, cabernet sauvignon is the world's most-planted wine grape, dominating vineyards from Napa to Bordeaux. New research ...
Phys.org / Physicists drive antihydrogen breakthrough at CERN with record trapping technique
Physicists from Swansea University have played the leading role in a scientific breakthrough at CERN, developing an innovative technique that increases the antihydrogen trapping rate by a factor of ten.
Phys.org / Ancient and colonial legacies continue to shape Amazon forest biodiversity today
Human influence across centuries continues to define biodiversity and carbon storage in the world's largest rainforest, according to a new international study published in the Proceedings of the National Academy of Sciences ...
Phys.org / CT scans reveal hidden details of ancient copper smelting in early Iran
About 5,000 years ago, people living in what is now Iran began extracting copper from rock by processing ore, an activity known as smelting. This monumental shift gave them a powerful new technology and may have marked the ...
Phys.org / Sharper MRI scans may be on horizon thanks to new physics-based model
Researchers at Rice University and Oak Ridge National Laboratory have unveiled a physics-based model of magnetic resonance relaxation that bridges molecular-scale dynamics with macroscopic magnetic resonance imaging (MRI) ...
Phys.org / How bacteria 'feel' surfaces: Fluorescent probe visualizes and quantifies membrane tension
In natural environments, bacteria rarely live as free-swimming cells but are attached to surfaces as biofilms in medical devices, mobile phones or human tissue. The bacterial behavior, how they attach and grow, group together ...
