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 / 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 ...
