Scientists Finally Created A White Laser -- And It Could Light Your Home

Lasers have been advancing science and threatening move characters since the 1960s, but you may have noticed they always have a distinct colour. Now, a team of scientists has developed the world’s first white laser.


Beautiful Video Explains How Light Has Been Harnessed For Communication

Whether you have fibre supplying Internet access to your home or not, you use optical systems to send and receive information every single day. This stunning video takes a look at the scientists and engineers that have enabled light to be used for human communication.


Scientists Can Turn Human Cells Into Working Lasers

How about this for a bright idea: A team of researchers from Harvard Medical School has developed three different ways to turn individual cells into functioning lasers that emit light when they’re excited.


This Tiny Light-Emitting Device Flashes 90 Billion Times A Second

This may look like a piece of abstract art, but you’re actually looking at the cutting-edge of optical technology. Using a branch of physics known as plasmonics, this microscopic set-up can pulse light on-and-off a bewildering 90 billion times per second.


Your Yard Is A Firefly Meet Market, And You Can Help Scientists Study It

The twinkly flashing lights of fireflies are a classic sign of summer, but the insects aren’t blinking for your aesthetic benefit. They’re courting in an absolutely cutthroat meet market, and some scientists are afraid that human activities could be making it harder for them to succeed.


This Is How Valve's Amazing Lighthouse Tracking Technology Works

Valve’s virtual reality demo at GDC was nothing short of magical — it used fancy emitter technology to let us actually walk around a demo room. It felt so real. Valve calls the tech Lighthouse, and it’s kind of genius.


Clever Short Film Is Made Completely With Light Paintings

Video: Light painting is usually used to snazz up still photographs in an awesome ‘how they do that’ kind of way but this is even cooler. Darren Pearson made this entire video of moving light paintings by hand drawing over 1000 light paintings and capturing them with long exposure at night to create the effect as if the light was alive and characters in a movie.


Colour -- Not Just Light -- May Affect Our Body Clock

It’s well-known that our body responds to light and dark to help set its circadian rhythms. But new research suggests that our bodies may also respond to colour in order to keep internal time.


Tech Startup Aims For 52-Megapixel Cameras In Phones By 2016

I think we can all agree that the situation with cameras and megapixels has reached maddening heights. DSLRs are expected to have insane resolutions, but mobile phones? No one was really asking for 50+ MP shooters in their iPhones and Galaxys by the end of 2016, but it’s looking possible thanks to a new startup called Light.


You Need To Spend More Time In The Dark To Sleep Better

Today most people do not get enough sleep. The Centers for Disease Control and Prevention (CDC) has called insufficient sleep an epidemic. While we are finally paying attention to the importance of sleep, the need for dark is still mostly ignored.
