Radio waves don’t travel well through water, which is why devices such as ROVS (remotely operated vehicles) have to be linked to their operator via a communications cable. According to a new study, however, solar panels may soon allow for practical und… Continue reading Solar cells used to boost wireless underwater communications
Having your blood pressure measured via an inflatable arm cuff can be stressful, potentially causing that pressure to be higher than normal when the reading is taken. A new finger clip device, however, is promised to make the process quicker and easier… Continue reading Finger clip could find use in less stressful blood pressure tests
Bubble lights are mesmerizing things to watch, up there with lava lamps as one of the nicer aesthetic creations of the mid-20th century. [Tech Ingredients] decided to head into the …read more Continue reading Bubble Lights Made From Scratch
Because nanoscale objects are so incredibly small, they don’t reflect enough light for even the best microscopes to discern details such as their color. A new lighting system, however, addresses that problem by acting as a tiny spotlight.Continue Readi… Continue reading Nano-spotlight used to capture first color photos of carbon nanotubes
As we age, our eyesight naturally declines but a new study has found exposing our retinas to short bursts of deep red light can help deteriorating vision. The research shows just three minutes of exposure to 670-nanometer (long wavelength) deep red lig… Continue reading Brief exposure to near-infrared light improves deteriorating vision
Blind corners have long troubled drivers, but they might not pose such a hazard for much longer. Researchers at Northwestern University have developed a new holographic camera technology that can peer around corners by reconstructing scattered light wa… Continue reading Holographic camera reconstructs objects around corners in milliseconds
Ordinarily, if you want to check if two plants of the same species come from genetically different populations, you have to analyze their DNA. A new study, however, has found that an analysis of the reflective qualities of their leaves is a much quicke… Continue reading Leaf-reading tool could replace DNA analysis for plant identification
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… Continue reading Wireless power transmission tech demo uses lasers to run 5G station
Linear transforms — like a Fourier transform — are a key math tool in engineering and science. A team from UCLA recently published a paper describing how they used deep …read more Continue reading Fourier Transforms (and More) Using Light
Although solar-powered devices are now fairly common, Swedish scientists have created something a little different. They’ve built tiny “metavehicles” that are mechanically propelled and guided via waves of light.Continue ReadingCategory: ScienceTags: L… Continue reading Microscopic metavehicles are pushed and steered by light
