The surprising new particle that could finally explain dark matter

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but remain undetectable due to their scarcity. With detectors like JUNO and DUNE, researchers now have a chance to spot their unique signal, a breakthrough that could link particle physics with gravity.

The phantom heat of empty space might soon be detectable

A Hiroshima University team has designed a feasible way to detect the Unruh effect, where acceleration turns quantum vacuum fluctuations into observable particles. By using superconducting Josephson junctions, they can achieve extreme accelerations that create a detectable Unruh temperature. This produces measurable voltage jumps, providing a clear signal of the effect. The breakthrough could transform both fundamental physics and quantum technology.

Ordinary ice found to have shocking electrical powers

Scientists have discovered that ordinary ice is a flexoelectric material, capable of generating electricity when bent or unevenly deformed. At very low temperatures, it can even become ferroelectric, developing reversible electric polarization. This could help explain lightning formation in storms and inspire new technologies that use ice as an active material.

Neutrinos may be the hidden force behind gold and platinum

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, showers of radiation, and even the building blocks of gold and platinum. Now, new simulations from Penn State and the University of Tennessee Knoxville reveal that elusive particles called neutrinos—able to shift between different “flavors”—play a crucial role in shaping what emerges from these cataclysmic events.

First identification of a heavy element born from neutron star collision

For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars. The detection confirms that the heavier elements in the Universe can form in neutron star mergers, providing a missing piece of the puzzle of chemical element formation.

World record acceleration: Zero to 7.8 billion electron volts in 8 inches

To understand the fundamental nature of our universe, scientists would like to build particle colliders that accelerate electrons and their antimatter counterparts (positrons) to extreme energies (up to tera electron volts, or TeV). With conventional technology, however, this requires a machine that is enormously big and expensive (think 20 miles long). To shrink the size and cost of these machines, the acceleration of the particles — how much energy they gain in a given distance — must be increased.
