This video explains how LEDs (Light Emitting Diodes) work and why they’ve become one of the most important components in modern electronics. Found in phones, TVs, headlights, indicators, and even ...

The researchers’ custom near-infrared LED heating system activates SnOx nanoflakes that heat and neutralize cancer cells (green: live cells; red: cells killed by photothermal therapy). Credit: ACS ...

LG’s attempts to prove that it’s much more than just an OLED TV brand have taken their most spectacular turn yet with the launch of a new 136-inch Micro LED display targeted at home cinema fans that ...

An international team of researchers has, for the first time, comprehensively assessed the state of the art of commercial UVC LEDs and summarized the findings in an open-access review. These compact, ...

Waveshare’s RP2350-Matrix is a Raspberry Pi RP2350A-powered LED matrix board featuring 64 RGB LEDs (8×8 RGB matrix), a built-in 6-axis IMU, and a Dout pin in case the user needs even more LEDs. The ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

HACK Lab HackLED Pro is an Adafruit Sparkle Motion-like LED controller that runs a custom version of WLED and supports both WS2812 and RGBCW LEDs, making it ideal for DIY lighting projects, smart home ...

Dozens of machine learning algorithms require computing the inverse of a matrix. Computing a matrix inverse is conceptually easy, but implementation is one of the most challenging tasks in numerical ...

We present a novel tactile sensor based on a matrix of light emitting diodes (LEDs). Unlike previous optical-based tactile sensors this approach relies on only one matrix of elements to perform the ...

Dr. James McCaffrey from Microsoft Research presents a complete end-to-end demonstration of computing a matrix inverse using the Newton iteration algorithm. Compared to other algorithms, Newton ...

“Using an at-home mask is like going to the gym,” says Shereene Idriss, MD, a board-certified dermatologist and founder of Idriss Dermatology in NYC. To truly see any skin care benefit, you need to ...
