After powerful earthquakes rumbled in Ridgecrest, California, NASA and Caltech researchers released four ballons into the air to detect the aftershock’s sound waves. (Image Credit: NASA/JPL-Caltech)   Sometime between July 4th and July 6th, 2019, powerful earthquakes struck near Ridgecrest, California, setting off over 10,000 aftershocks. Taking advantage of this event, researchers from NASA’s Jet Propulsion Laboratory and Caltech flew high-altitude balloons mounted with instru ...
Roboscientific’s team claims that their newly-developed system can detect COVID-19 in the air with 100% accuracy. (Image Credit: Roboscientific)   I’m sick today. My immediate thought − is it covid19? Temp checks, symptom lookups, frantic worry I'll get my family sick. I wish something like this was omni-present in all our homes.   British scientists at Roboscientific developed a sensor with COVID-19 detection capabilities. Once deployed in an indoor environment, it ...
This Partula hyaline snail rested on wild red ginger leaf with an M3 system. (Image Credit: Inhee Lee)   After introducing predatory snails to Tahiti in the 1970s, 56 tree snail species became extinct, but the Partula hyalina remained. University of Michigan scientists and biologists outfitted a P.hyalina with an M3 computer to determine how it survived such an onslaught. These white-shelled snails can withstand more sunlight, allowing them to endure sunlight forest edge habitats. The worl ...
(Image Credit: Marko Blažević)   Back in 2012, IBM announced a prediction of 1 trillion connected IoT devices by 2015, a staggering number that was not reached at the time. During that same year, Ben Calhoun and Dave Wentzloff, MIT graduates, co-founded “Everactive” and collaborated to develop power-efficient circuits. They realized that managing 1 trillion IoT devices would be very challenging since the sensors need batteries to collect, transmit, and analyze data. To face thi ...
This project shows how to use the Analog Discovery Studio's Oscilloscope to measure the natural electrical potential generated by the heart (ECG). As the measured signal is of very low amplitude, it first needs to be amplified with external circuitry, which can be built on the Breadboard Canvas and supplied from the Analog Discovery Studio Power Supplies. With the help of WaveForms, the received data is sent to LabVIEW, where the postprocessing is done.   Analog Discovery Studio is a ful ...
The team used magnets on a plane and a three-axis magnetic sensor to track a magnet's position.  (Image Credit: ACM SIGCHI)   Researchers from Ochanomizu University and other institutions created FieldSweep, a 2D tracking system on a plane that utilizes permanent magnets and a smartphone. Their technique tracks the smartphone's position while it slides above the magnets. The three-axis magnetic sensor measures the plane's magnetic field, which was produced by the permanent magnets. It ...
