New quantum gravity sensor could someday peel away the surfaces of other worlds

To find features like groundwater under Earth‘s surface — or under the surface of another world — scientists can sense the subtle marks those features leave in the planet’s gravitational field. But those measurements aren’t easy to get; you need very sensitive instruments, and even the slightest vibrations can throw off the measurements. Now, a … Read more

New Quantum Gravity Sensor Can Look Under Earth’s Surface in Unprecedented Detail

Scientists would be able to discover much more about what lies underground if our planet could be sliced open and viewed as a cross-section – but as that’s not really possible, they have to rely on a variety of other methods instead.   One new approach has just been proven in the field: A recently … Read more

New Sensor Tells You How Well Your Mask Is Working

Researchers have developed a lightweight, reusable sensor that clips onto a mask to monitor how well it’s working. The device, called FaceBit, senses leaks and records wear time while continuously measuring a wearer’s heart and breathing rate. Its developers hope it will aid research and help health care workers and others who wear face coverings … Read more
