We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to ...

How the Kisan Mitra Chhadi works, from its 5 to 15-metre detection range to the vibration alert that could help farmers avoid ...

The new electronic intervention called ‘Kisan Mitra Chhadi’ is intended to reduce the many lives lost to snake bites in rural ...

The ESP32 does everything a Pi Pico does, but costs less and lasts 100x longer on batteries ...

Think about how easily you recognize a friend in a dimly lit room. Your eyes capture light, while your brain filters out background noise, retrieves stored visual information, and processes the image ...

Researchers have built new photonic computing chips that allow neural networks to learn using light instead of electronics. The technology could improve autonomous vehicles and help robots learn ...

A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, ...

You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

Thanks to modern LED bulbs, light is cheaper than ever to make—except for one particular kind. Three University of Chicago scientists have announced an innovative way to create infrared light, which ...

Dark matter will help explain not only how our universe was made, but also its components. It will help people understand fundamental physics and how additional particles and forces exist. The ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...

If you ever built a line following robot, you’ll be nostalgic about [Jeremy’s] light-seeking robot. It is a very simple build since there is no CPU and, therefore, also no software. The trick, of ...
