Quantum physical experiments exploring the motion of macroscopic or heavy bodies under gravitational forces require protection from any environmental noise and highly efficient sensing. An ideal system is a highly reflecting gravitational wave mirror whose motion is sensed by monochromatic light, which is photoelectrically detected with high quantum efficiency. A quantum optomechanical experiment is achieved ...
Having trouble hearing? Just turn up your shirt. That’s the idea behind a new “acoustic fabric” developed by engineers at MIT and collaborators at Rhode Island School of Design. The team has designed a fabric that works like a microphone, converting sound first into mechanical vibrations, and then into electrical signals, similar to how our ...
The first worlds beyond our solar system were discovered three decades ago. Since then, close to 5,000 exoplanets have been confirmed in our galaxy. Astronomers have detected another 5,000 planetary candidates — objects that might be planets but have yet to be confirmed. Now, the list of planets has shrunk by at least three. In ...
Researchers have developed a new method to display highly realistic holographic images using ‘holobricks’ that can be stacked together to generate large-scale holograms. The researchers, from the University of Cambridge and Disney Research, developed a ‘holobrick’ proof-of-concept that can tile holograms together to form a large seamless 3D image. 3D displays using ‘holobricks’ This is ...
Stem cell treatments are still in the experimental stage, with a lot more advanced research required before treatments make it into the mainstream. However, that hasn’t stopped American “stem-cell tourists” from traveling to unregulated clinics in Mexico, the Caribbean, and China searching for stem-cell treatments for just about anything, from heart treatments to facelifts. In ...
A brown dwarf is often referred to as a “failed star”; however, astronomers have discovered a 23-million-year-old dwarf that flashes brighter than the Sun’s most powerful flares. The research team from the University of Delaware, led by John Gizis, a professor in the Department of Physics and Astronomy, discovered the “ultra-cool” brown dwarf known as ...
The excavation of an abandoned mausoleum and silver extraction taking place on an industrial scale at a Roman site in rural Kent has left archaeologists with a 1,500-year-old mystery. Excavation found silver extraction on an industrial scale Archaeologists working on an excavation at Grange Farm, near Gillingham, discovered 15 kilograms of litharge — a material ...
In a mad rush to gain hits to their sites, media outlets are at it again with headlines such as: “SURPRISE: Earth has two moons” and “Earth now has a second moon” or even “Earth has a second mini-moon, says NASA.” So did NASA say anything about a moon? No. While headlines such as the ...
When two neutron stars spiral into one another and merge to form a black hole — an event recorded in 2017 by gravitational wave detectors and telescopes worldwide — does it immediately become a black hole? Or does it take a while to spin down before gravitationally collapsing past the event horizon into a black ...
A bold plan to synthesize an entire human genome has been scaled back, aiming at a more technically attainable near-term goal. Instead of synthesizing all of the human genome’s 3 billion DNA base pairs, the project will now attempt to recode the genome to produce cells immune to viral infection. What is the Human Genome ...
