Phys.org / A new type of LED light could bring significant efficiency gains
Researchers at Lund University have developed a new type of light-emitting diode based on thin, branched nanowires that could offer significantly higher efficiency and lower production costs than current technology. By controlling ...
Phys.org / Away from grand temples, a recycled Bronze Age burial mound became the focus of a Roman religious complex
The Romans were master engineers, building sprawling road networks, towering aqueducts and arenas across their empire. They were also good at recycling. New research has revealed that they turned the remains of a 4,000-year-old ...
Phys.org / Sorry, this neutrino laser won't work, physicists say
Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second. The elementary particles are often described as "ghostly" for ...
Medical Xpress / End of free school meal program led to increased stress and hunger, poorer diets and reduced focus, say teachers
How did students' diets and behavior change after the expiration of a pandemic-era universal free school meal program in 2022? Researchers asked teachers for their observations of the impact on students and found that teachers ...
Phys.org / One unexplained event could hint at heavy dark matter
An unexplained signal detected by the world's most sensitive dark matter experiment could mark a major breakthrough in the hunt for the elusive substance, according to an analysis involving scientists from the University ...
Medical Xpress / Energy-hungry tissues expand cleanup crews to clear worn-out mitochondria
The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture) and brown fat (for heat production) each require a lot of energy and make a lot of waste. That waste needs to be managed.
Phys.org / Small molecular substitutions reshape energy pathways behind aggregation-induced emission
Certain chemical substances, broadly called luminogens, have an inherent ability to emit light. Most fluorescent molecules emit light in solution but lose their emission in the solid state, where the molecules aggregate.
Phys.org / Physicists finally put Feynman's path integral to the test
For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.
Phys.org / Geomagnetic superstorm shook GPS accuracy across the US—its timing may have averted agricultural losses
On Nov. 11, 2025, Earth experienced a severe geomagnetic storm triggered by solar flares and coronal mass ejections from an active sunspot region. While this kind of storm brings beautiful auroras admired in many areas around ...
Phys.org / Weak sea-surface temperature gradients may fuel stronger tropical cyclones
The fact that the ocean gets colder as you go deeper is fairly intuitive, but a similar gradient exists along the surface of the ocean, even at scales of 1 kilometer to tens of kilometers. A new study, published in the Proceedings ...
Medical Xpress / Cancer drug tames atherosclerosis inflammation and plaque in animal models
A new Yale study has identified a promising therapeutic avenue for atherosclerosis, a condition caused by inflammation and plaque buildup in arteries. Martin Schwartz, Ph.D., Robert W. Berliner Professor of Medicine (Cardiology) ...
Medical Xpress / Smoking's social myth challenged as 50,000-person study links it to loneliness
Smoking is not social and leads to increased loneliness, according to a large Europe-wide study presented at the European Respiratory Society (ERS) Congress in Barcelona, Spain.
