Opening a new window into quantum physics

A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement.

Novel LEDs pave the way to cheaper displays

OLEDs are already used in the displays of smart phones or digital cameras today. They offer an especially bright image with high contrast, but come with a serious drawback: typically, only one quarter of the electrical energy invested in running the device is actually converted into light.

Geodesic dome constructed out of 4,800 plastic bottles and LEDs

I love art that plays tricks on my eyes, making me see something that isn’t there but is. The upcycled ‘Rising Moon’installation created for last month’s Mid-Autumn Festival in Hong Kong is just such a piece of art.

Cheaper, "greener'" lighting with inkjet-printed hybrid quantum dot LEDs

We all know It's not exactly easy going green. For home lighting applications, organic light emitting diodes (OLEDs) hold the promise of being both environmentally friendly and versatile.

FIPEL lights could replace LEDs

The lighting, based on field-induced polymer electroluminescent (FIPEL) technology, also gives off a soft, white light, rather than the yellowish tone of fluorescents or LEDs' bluish tinge.

Fish scale research could improve optical devices

A trick used by fish to overcome a basic law of physics could lead to improvements in the efficiency of LED lights.

Sony's new TV based on six million LEDs

Sony's shown off a new type of LED television which uses six million tiny light-emitting diodes to create an image.

'Eco' lights could cause cancer

LEDs are one of the few types of lighting that actually give you enough light to see by, while still being good for the environment... or maybe not.
