New LED Blue Lights Could Control Sleep Patterns With The Flick of Switch

Blue light from conventional LED lamps and displays can mess up your sleep patterns. These new lights aim to solve this.

Researchers create hi-tech, quantum-dot LED light using discarded rice husks

About 100 million tons of rice husk are produced every year. Why not use it to create new things?

LED-equipped fishing nets help protect wildlife from unintentional captures

The fish we want to capture aren't turned away by the lights.

Samsung may be on the brink of self-emissive QLEDs

The QLED TV sets you see on Amazon aren't actually the real deal. This is what genuine quantum dot-based displays might look like.

The LED sun: artificial sunlight mimics natural light

A natural skyline at the flick of a switch.

Novel material paves the way for atom-thin, invisible displays

The future is now!

New, cheap artificial photosynthesis scrubs the air and produces fuel

Currently only works with blue light, but they're working on fixing that.

Cheaper, brighter and easier to manufacture LEDs created from organic-inorganic hybrid class of materials

Florida Researchers have developed a new class of LEDs that may change the lighting and display industry of the future.

Blue visible light can be used as insect killer, research shows

Keeping insects at bay is more than eliminating a simple nuisance - in many some parts of the world, it's vital. Malaria, an infectious mosquito-borne disease kilss over 500,000 people every year, and the disease could be kept under control if the mosquito population was kept under control; this is where this study steps in.

Lightpaper prints LEDs and ink on incredibly thin surfaces

When I first heard about 3-D printing, I was completely stoked. The whole concept blew me away and changed forever what I thought of ‘printing’. We now also know about machines that print metals, food and even human organs, why not light too? While not a 3D printer, Rohinni’s Lightpaper technology can be credited as […]

Forget incandescent light bulbs, make way for quantum dot LEDs

Capable of illuminating in a wide array of pure colors and operating at high efficiency, quantum dot LEDs are set to become the future’s foremost illuminating medium. However, at this time, these fantastic quantum dot light emitting diodes are limited by a physical effect which triggers after a certain photon barrier is crossed, becoming highly […]

Natural brightness: fireflies inspire LEDs with 55% more efficiency

We’ve featured countless research here on ZME Science where important scientific and technological advancements were made after scientists sought inspiration from nature, be them  high-tech surfaces (butterfly) or robots (leaping lizard). Recently, researchers at Canada’s University of Sherbrooke managed to improve LED efficiency by 55% after they applied a coating etched with a profile similar to that […]

NASA to test sleep-aid coloured light bulbs

Space flight insomnia is quite a common issue, one for which space agencies don’t have a definite answer yet – but they’re working on it; one thing NASA plans to do is swap a fluorescent panel with a solid-state lighting module (SSLM) containing LEDs which produces a blue, whitish or red-coloured light depending on the […]

Curing jet lag with timezone adjusting LED glasses

Along with technology came a series of new afflictions that plagued mankind. Most of them are psychological, like internet addiction or the ever worrisome jet lag. The latter is a big problem for millions of people regularly traveling in different time zones, causing them to miss hours of sleep, feel extremely tired, not eat well […]

[ZME Contest] WIN solar charger and Rechargeable LED Work light

Hey, guys! We’ve received some great feedback from our previous contest, when we offered an awesome DNA portrait to one of our readers. Naturally, we’d like to follow with yet another giveaway and hopefully turn this into a frequent feature on ZME Science. It’s the least we can do for all your generous support you’ve […]

MIT engineers create LED that has 230% efficiency. Thermodynamics laws still in place

A group of researchers at MIT have successfully managed to create a light emitting diode (LED) that has an electrical efficiency greater than 100%. This might sound preposterous, and against everything you learned in physics, however the system is still governed by fundamental laws of thermodynamics. This extraordinary power conversion efficiency was obtained by a […]

MBE machine grows gadgets one atom at a time

Dubbed MBE, after the intricate molecular beam epitaxy process, this device developed by scientists at Sharp Laboratories in Oxford, England, can actually grow electrical components at a dazzling precision atom by atom. This is where razor sharp technology is at, as far as manufacturing goes, and this monstrous-looking device is capable of transferring atoms from […]
