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 …

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 …

A SpaceX Falcon 9 rocket streaks away from Launch Complex 39A at NASA’s Kennedy Space Center to begin the USSF-36 mission with the X-37B spaceplane onboard. More than eight minutes after liftoff, the first stage booster, tail number 1092, landed with a sonic boom at Landing Zone 2.

Image by Valeria Blanc / Getty Images Researchers have come up with a potentially groundbreaking — and entirely laser-free — alternative to LASIK, a popular surgical procedure that uses high-power lasers to reshape the cornea to correct vision problems. During a meeting of the American Chemical Society, a team of scientists led by Occidental College chemistry professor Michael Hill showed …

Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal Scientific Reports. Per the authors, it’s the first example of a biolaser cavity within the animal kingdom. As previously reported, the bright iridescent colors in things like peacock …

Scientists at the European Space Agency used a laser to communicate with a spacecraft 165 million miles (265 million kilometers) away in deep space for the first time, marking a major step forward in their efforts to build optical communication systems for future missions to the Moon and beyond. Scientists at the Kryoneri Observatory near Athens, Greece, shot a powerful …
