One of the key marketing points of the Apple AirTag is “Precision Finding,” which shows you the precise location ...

The Johns Hopkins men's track and field team combined for seven top-10 and 15 top-25 finishes Saturday at the Tufts Cupid Challenge and the Widener ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This project presents a portable Arduino-based digital instrument for railway track inspection that measures super elevation (cant), track gauge, and rail temperature. Built around an Arduino Nano, ...

A recent study published in The Astrophysical Journal Letters has provided the most precise distance to the Coma Cluster of galaxies yet — and also has deepened a crisis in cosmology. The problem is ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets seem to have been knocked out of their orbits, floating through space free ...

Most planets spend their lives orbiting a star, but some are destined for exile. According to a study published in Science on Jan. 1, 2026, astronomers have successfully measured the mass and distance ...

Have you ever wondered how a robot navigates a cluttered room or how a drone maintains its altitude with pinpoint accuracy? The secret lies in the tools used to measure distance, an often-overlooked ...

Hamamatsu Photonics is pleased to introduce the G15978-0020P, an exciting new InGaAs Avalanche Photodiode that redefines the possibilities in compact sensor technology. Designed specifically for ...
