[ad_1] This staggering performance is made possible through 189 sensors, known as charge-coupled devices (CCDs) that each measure 16 megapixels. The CCDs are packaged into units called “rafts,” which make up the camera’s focal plane. There are 21 rafts, plus four specialty rafts not used for imaging. Altogether, the focal plane contains 3.2 billion pixels. […]

Alphabet’s Loon balloons are helping scientists study gravity waves
[ad_1] In between beaming internet to people in developing countries and sometimes passing for UFOs, Alphabet’s Loon balloons have been busy helping scientists study how our planet works. A team led by Stanford professor Aditi Sheshadri recently published a report on gravity waves, ripples created by gravity when it pushes down on air forced up into the Earth’s upper […]
NVIDIA’s chief scientist developed a low-cost, open-source ventilator
[ad_1] The ventilator can be assembled in just minutes, attached to a simple display and packed into a Pelican carrying case. Dally built the prototype using off-the-shelf components for about $400. Produced in quantity, it could cost less than $300, and using open-sourced, 3D-printed parts, the price might drop below $100, he says. According to […]
Stanford, Scripps and Fitbit try using wearables to detect infections
[ad_1] The smartwatch on your wrist might one day be key to containing the spread of viruses like the one behind COVID-19. Stanford, Scripps Research and Fitbit have unveiled an initiative that, if successful, would use wearables to catch the early signs of infection. They’re developing algorithms that would look for the elevated heart rates […]
Stanford moves classes online to deal with coronavirus outbreak
[ad_1] Final exams will still take place when possible, but they’ll have to be take-home exams. If a remote class or exam isn’t an option, Stanford will let professors look for alternatives to those methods or even submit grades based on work to date. The campus itself will remain open, although Stanford is encouraging remote […]
Stanford’s new tech-laden hospital includes pill-picking robots
[ad_1] The pharmacy will include robots that pick pills and pack them in backs, with other robots delivering them to dispensing stations. This frees up the humans for more involved tasks. Another 23 automated guided vehicles, meanwhile, help with delivering laundry and taking out the trash. Sensors track both equipment and staff in real time […]
Sticker sensor monitors your body using wireless power
[ad_1] The antenna proved to be the main challenge. They only had to screen-print metallic ink on a rubber sticker to create the antenna, but its signals could weaken as the body moved. The scientists had to develop a novel RFID system that could reliably send signals despite the constant changes. The receiver itself is […]
Researchers create eye-tracking glasses that auto-focus where you look
[ad_1] The authors note that, over time, our ability to refocus at near distances worsens as the lenses in our eyes stiffen. The condition, called presbyopia, typically kicks in at around age 45 and it affects more than a billion people. It’s a key factor as to why many of us need to start wearing […]
Stanford students’ robot dog does backflips for (relatively) cheap
[ad_1] It’s tiny, but it’s also more powerful than you might think. As it’s both very light and dense, it can jump as high as 3.5 feet in the air. This isn’t the most sophisticated robot. It requires manual control, and it’s not about to hold the door for you. The relatively affordable off-the-shelf parts […]
Playing ‘Pokémon’ as a kid may have rewired your brain
[ad_1] Scientists already knew that humans have specific areas of the brain used to recognize faces, words, numbers and even celebrities like Jennifer Aniston, Bill Clinton and Kobe Bryant. Those areas of the brain are often in the same place for large groups of people. A recent study by Harvard Medical School found that for […]
