Lasers are one of the tools physicians can lean on to tackle plaque buildup on arterial walls, but current approaches carry a risk of complications and can be limited in their effectiveness. By bringing ultrasound into the mix, scientists at the University of Kansas have demonstrated a new take on this treatment that relies on exploding microbubbles to destroy plaque with greater safety and effic
High-powered lasers have a hand in everything from manufacturing to deep space communications, and the ongoing development of more powerful versions calls for a rethink on the components responsible for steering their beams of light. This has a team of Harvard engineers turning to one of the strongest known materials in diamonds, which they've used to form a new mirror that can endure laser beams
A team of European researchers has suggested that the Moon’s orbit could be used as a gigantic detector for gravitational waves – ripples in the very fabric of spacetime itself. These waves, much smaller than those that existing detectors can pick up, could originate from the early universe.Continue ReadingCategory: Physics, ScienceTags: gravitational waves, Astronomy, Moon, Earth, LIGO, Laser, U
Wireless power has the potential to be very useful, but range is a major hurdle. In a new proof-of-concept project, Ericsson and PowerLight Technologies have demonstrated a technique called optical beaming, using a laser to transmit power to a portable 5G base station.Continue ReadingCategory: Energy, ScienceTags: Electricity, Electric, Energy, Wireless, Wireless Charging, Wireless Power Transmis
Even though it's now possible to 3D-print foods into millimeter-precise shapes and forms, cooking those printed foods is still a fairly inexact process. Scientists are trying to change that, by using lasers to cook foods to specific optimized standards.Continue ReadingCategory: ScienceTags: Columbia University, 3D Printing, Laser, Cooking, Food technology
Alphabet's floating internet venture Project Loon may have been deflated, but its legacy looks set to live on through a new effort called Project Taara. The team has salvaged the technology to deliver internet connectivity with lasers, demonstrating the viability in a new test between two cities separated by the Congo River.Continue ReadingCategory: Telecommunications, TechnologyTags: Internet, C
Airtext has released a simple laser altimeter for small aircraft to make approaches and landings safer. The app-controlled Land-DAR (Land Distance and Ranging) is configured through an iOS or Android app and calls out altitudes as the aircraft descends.Continue ReadingCategory: Aircraft, TransportTags: Aircraft, Navigation, Safety, Flight, LIDAR
Scientists at the University of Nottingham have developed a first-of-its-kind imaging sensor designed to be deployed inside the human body to build 3D maps of cellular structures. The prototype device, which combines lasers and sound waves in an optical fiber no thicker than a human hair, could be used in conjunction with standard endoscopes to reveal abnormalities in cells indicative of cancer.C
Whether you're a farmer tending to expansive crops that you depend on for your livelihood or a hobbyist gardener trying to keep your tomatoes in check, weeds can be a time-consuming and relentless problem. Startup Carbon Robotics has wheeled out an autonomous machine that has these pesky plants in its cross hairs, using a combination of computer vision and high-powered lasers to comb fields and t
Judging how ripe a piece of fruit is can be a frustrating process for everyone from farmers to shoppers. Now, researchers at Shibaura Institute of Technology (SIT) in Japan have developed a new high-tech way to check, without touching or damaging soft fruit like mangoes. All it takes is a laser and some plasma shockwaves.Continue ReadingCategory: ScienceTags: Food, Fruit, Laser, Food technology is a social bookmarking place where you can share, find & discuss the best news around on most topics.
