Cutting a photon in two creates an infinite swarm of particles

By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway ...

Biohybrid microrobots repair spinal cord by combining stem cells with magnetoelectric nanoparticles

Spinal cord injuries can have devastating consequences for those affected. Nerve cells in the spinal cord rarely regenerate naturally, while scarring often prevents the regrowth of nerve fibers. Modern therapies attempt to ...

Why the most massive galaxies in the early universe stopped forming stars prematurely

Astronomical observations show that the most massive galaxies in the early universe formed approximately three to four billion years after the Big Bang and stopped producing stars very early in cosmic history, around one ...

The solar wind's secret hammerheads and what they tell us about heat in space

The proton sharks showed up on a Friday. In a routine data calibration meeting for NASA's Parker Solar Probe in 2020, a small group of scientists were scrolling through visualizations of their data showing solar winds. Suddenly, ...

Spin wave signals used in computing boosted more than 5,000 times in Z-shaped path approach

A research team from Tohoku University, Shin-Etsu Chemical Co., Ltd., and École Polytechnique Fédérale de Lausanne (EPFL) has invented a new way to efficiently guide spin waves around sharp corners with minimal loss—representing ...

Is my brain wired to never see a ghost? A psychologist on three factors that make a paranormal experience more likely

Around 1 in 5 Americans say they've seen a ghost. I'm not one of them, and I probably never will be. I blame my brain.

Researchers push back fundamental limit on energy transfer between particles without 'spilling' radiation

Researchers at TU/e have demonstrated that energy transfer without loss via light or heat can occur over much greater distances than previously thought possible thanks to vibrations in microscopic gold rods. They succeeded ...

Metamaterials enable control of heat transfer at nanoscale, potentially transforming energy and electronics

Heat behaves in predictable ways: a hot cup of coffee cools, a laptop warms your hands, the sun heats Earth. But at scales thousands of times smaller than a human hair, those rules begin to break down, and scientists are ...
