The ionosphere is of great importance to shortwave radio transmissions, since it allows radio waves to be refracted and ...

Working with multiple sensors on an Arduino can unlock richer, more interactive projects. By integrating motion, light, distance, and environmental readings, you can create systems that respond ...

A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using classical sensors alone. Such quantum sensors are currently being used to study ...

MIT researchers have created a quantum sensor that can measure multiple physical quantities at high-resolution. The sensor is made from so-called nitrogen-vacancy centers in diamonds, where a carbon ...

Scientists at the University of Maryland have created Smart Underwear, the first wearable device designed to measure human flatulence. By tracking hydrogen in flatus, the device helps scientists ...

Congress took steps on Wednesday toward blocking changes to D.C.’s local tax code, even as District officials warned it could wreak havoc on tax season and smash a hole in the city’s budget. The House ...

AI is already having a seismic impact on how software is written, with much of the grunt work of programming now performed by swarms of agents and subagents. But as developers experiment with new ...

Amid ongoing tension between its members, the West Covina City Council voted unanimously to add a “Code of Conduct” to its municipal code. The measure requires a second reading before adoption. The ...

SEATTLE — The Pacific Northwest Seismic Network (PNSN) announced their upcoming collaboration with the Seattle Seahawks and Lumen Field to measure ground motion during the 2026 NFL Playoff Games. On ...

Quantum sensors are transforming how we measure and navigate, offering levels of precision far beyond classical systems. By exploiting atomic superposition, cold atom interferometers, and diamond NV ...

Before every shot, every golfer makes the same decision: they judge distance. In the fairway, range finders, GPS devices and even the occasional sprinkler head help calculate the distance to the flag.

PCWorld explains how to create an affordable CO2 air quality monitor using a Raspberry Pi and MH-Z19C sensor for under $40. This DIY project helps monitor indoor air quality since high CO2 levels ...
