Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously elusive subatomic particles.

Scientists at MIT discovered that chaotic laser light can spontaneously form a highly focused beam instead of scattering—if the conditions are just right. This “pencil beam” enabled them to image the ...

For more than half a century, the search for extraterrestrial intelligence has been built on the assumption that if aliens exist and try to communicate, their signals will be faint, scattered, and ...

MIT researchers discovered a paradoxical phenomenon in optical physics that could enable a new bioimaging method that's faster and higher-resolution than existing technology. They discovered that, ...
