An anonymous reader quotes a report from TechCrunch: “We want to miniaturize accelerator technology in a way that makes it a more accessible research tool,” explained project lead Jelena Vuckovic in a Stanford news release. But this wasn’t designed like a traditional particle accelerator like the Large Hadron Collider or one at collaborator SLAC’s National Accelerator Laboratory. Instead of engineering it…

MIT Reveals First Ever Laser Ultrasound Pictures of a Human Body
Researchers from MIT have revealed the very first images of a human generated through a novel laser ultrasound imaging technique. Unlike conventional ultrasound, the new technique does not require any skin contact with the body, dramatically amplifying the range of uses for doctors in clinical environments. New Atlas reports: A new non-contact ultrasound method involving lasers has now been effectively demonstrated…
The BBC’s 1992 TV Show About VR, 3D TVs With Glasses, and Holographic 3D Screens
dryriver writes: 27 years ago, the BBC’s “Tomorrow’s World” show broadcasted this little gem of a program [currently available on YouTube]. After showing old Red-Cyan Anaglyph movies, Victorian Stereoscopes, lenticular-printed holograms and a monochrome laser hologram projected into a sheet of glass, the presenter shows off a stereoscopic 3D CRT computer display with active shutter glasses. The program then takes us…
Laser-based prototype probes cold atom dynamics
By tracking the motions of cold atom clouds, astronomers can learn much about the physical processes which play out in the depths of space. To make these measurements, researchers currently use instruments named ‘cold atom inertial sensors’ which, so far, have largely been operated inside the lab. In new work published in EPJ D, a team of physicists at Muquans and…
New laser technique images quantum world in a trillionth of a second
For the first time, researchers have been able to record, frame-by-frame, how an electron interacts with certain atomic vibrations in a solid. The technique captures a process that commonly causes electrical resistance in materials while, in others, can cause the exact opposite—the absence of resistance, or superconductivity. …
Tesla Wants To Clean Windshields With Laser Beams
Tesla “may be keen on replacing the humble windshield wiper with lasers,” reports CNET. In a patent application filed this past May and published with the United States Patent and Trademark Office on Nov. 21, Tesla describes a “pulsed laser cleaning” for “debris accumulated” on glass, specifically for automotive application. It also mentions this could be used for “photo-voltaic” applications. That’s…
Gamma-ray laser moves a step closer to reality
A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. …
New instrument extends LIGO’s reach
Just a year ago, the National Science Foundation-funded Laser Interferometer Gravitational-wave Observatory, or LIGO, was picking up whispers of gravitational waves every month or so. Now, a new addition to the system is enabling the instruments to detect these ripples in space-time nearly every week. …
Did this huge black hole swallow a star from the inside out?
A recently discovered black hole in a distant spiral arm of the Milky Way, 70 times as heavy as the sun, might have swallowed a star from the inside out, and scientists are baffled. Source: https://earthsky.org/space/did-huge-black-hole-lb1-swallow-star-from-inside-out…
Ask Slashdot: What Happened To Holographic Data Storage?
dryriver writes: In an episode of the BBC’s Tomorrow’s World broadcasted all the way back in 1984, a presenter shows hands-on how a laser hologram of a real-world object can be recorded onto a transparent plastic medium, erased again by heating the plastic with an electric current, and then re-recorded differently. The presenter states that computer scientists are very interested in…
