Neutrinos are among the most abundant particles in the universe, but they are also among the most elusive. Nearly massless, they are produced by nuclear reactions in the sun, exploding stars, particle accelerators and even the decay of radioactive elements on Earth. They interact so weakly with ordinary matter that trillions pass through each person every second without leaving a trace. Studying these ghostly particles could help answer some of the biggest questions in physics, from the nature of dark matter to why matter exists at all. https://phys.org/news/2026-10-spine-machine-trail-ghost-particles.html General Physics Tue, 27 Oct 2026 15:10:01 EDT news712330469 For the first time, a team of physicists in the U.S. has clearly demonstrated a "helicon current drive" in a nuclear fusion experiment. Led by Jeff Lestz at General Atomics, San Diego, the team took advantage of the latest advances in tokamak technology to show that radio waves steered to travel around the donut-shaped device can be absorbed by its confined plasma, driving an electric current inside it. https://phys.org/news/2026-10-radio-fusion-plasma-current-reactors.html Plasma Physics Tue, 27 Oct 2026 07:20:01 EDT news712244375 Producers, consumers, and decomposers play different roles in today's ecosystems. Thinking about these familiar roles led me to a question: Could their differences partly reflect the different physical and chemical environments in which early life developed? I wondered whether the organization of ecosystems might offer a useful starting point for thinking about life's beginnings. https://phys.org/news/2026-10-ecological-roles-clues-life-began.html Ecology Mon, 26 Oct 2026 17:40:16 EDT news712234886 Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In plasmas, slight disturbances can grow due to instabilities, and energy is transferred between structures of various sizes due to turbulence. These phenomena give rise to structures ranging from very small to large, which significantly influence the overall motion and energy flow of the plasma. https://phys.org/news/2026-10-ray-pulse-reveals-plasma-nanostructures.html Plasma Physics Sat, 24 Oct 2026 15:00:06 EDT news711645235 Do cosmic radiation doses near the moon differ significantly from those received by astronauts in low Earth orbit?

The dip appears in data tracking collision-by-collision variations in the momenta of particles emerging from collisions between gold nuclei at RHIC, near RHIC's lowest collision energies. These collisions create the highest-density nuclear matter and may indicate that something interesting is happening in that dense region of the phase diagram.
