Neutrinos are one of the most enigmatic particles in the standard model. The main reason is that they’re so hard to detect. Despite the fact that 400 trillion of them created in the Sun are passing through a person’s body every second, they rarely interact with normal matter, making understanding anything about them difficult. To help solve their mysteries, a …

MIT physicists have proposed a way to make a super sci-fi-sounding device: a neutrino ‘laser,’ which could help us probe the mysteries of the Universe. Neutrinos are the most abundant particles that have mass, but in a cruel irony, they’re extremely elusive, earning them the term ‘ghost particle’. Although there are trillions of them zipping through your body at any …

Located 700 meters underground near the city of Jiangmen in southern China, a giant sphere—35 meters in diameter and filled with more than 20,000 tons of liquid—has just started a mission that will last for decades. This is Juno, the Jiangmen Underground Neutrino Observatory, a new, large-scale experiment studying some of the most mysterious and elusive particles known to science. …

MIT physicists propose a “neutrino laser,” a quantum-driven burst of neutrinos that could revolutionize communication and medical technology. Credit: Jose-Luis Olivares, MIT; Adapted by SciTechDaily.com Super-cooling radioactive atoms could create a laser-like neutrino beam, potentially opening a new avenue for studying these elusive particles and even enabling novel forms of communication. Every instant, torrents of neutrinos pass through our bodies …

Neutrinos are exceedingly common in the Universe, with billions of them zipping around us throughout the day from a variety of sources. Due to their extremely low mass and no electric charge they barely ever interact with other particles, making these so-called ‘ghost particles’ very hard to detect. That said, when they do interact the result is rather spectacular as …

In February 2023, a cosmic particle detector housed deep in the Mediterranean Sea recorded the arrival of a neutrino with approximately 20 to 30 times more energy than any other neutrino documented previously. Labelled KM3-230213A, the particle had a calculated energy of 220 petaelectronvolts (PeV), far greater than the 10 PeV of the previously most energetic neutrino. The finding generated …

Neutrinos are strange little things. This tiny, enigmatic particle with no charge exists in virtually every corner of the universe, but without powerfully sensitive, sophisticated instruments, physicists would have no way of knowing they exist. In fact, trillions are passing through you every second. Physicists devise all sorts of ways to coax neutrinos into the detection range. But IceCube—which celebrates …
