Light

Imagine a glow-in-the-dark designer desk, or wooden fence posts that guide you home with their eerie light. Scientists in Switzerland have developed a way to make glowing wood, with the help of a fungus.

The first direct visualization of the shape of a photon has been created. These particles of light are impossible to photograph, but UK physicists have now calculated their wave function to produce an accurate image of a photon as it’s emitted.

People with photosensitive epilepsy could soon be able to watch TV without worry. Scientists in the UK have created glasses that can block out specific wavelengths of light known to cause seizures.

New York might be known as the city that never sleeps, but it turns out there's a lot less shuteye happening in smaller urban areas across the globe. And it's not because of nightlife, but artificial light emitted from buildings and infrastructure.

Cranking up the air conditioner keeps buildings cool, but it guzzles energy. Passive materials can regulate temperatures more efficiently, and now scientists have developed a new coating that keeps glass much cooler, while still being transparent.

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. If you manipulate a laser just right, then hit it side-on with another light source, it’s possible to create this bizarre optical effect.

Scientists at the University College London have set a new world record in wireless data transmission speeds, sending a blistering 938 Gigabits per second (Gbps) over the air through a combo of radio and light technology.

Many indoor plant enthusiasts know that mirrors can be used to direct more sunlight onto plants that need it. Scientists have now developed a method of applying that same principle to tree seedlings that are struggling to grow in shady forests.

Astronomers have watched a supermassive black hole take two bites of a star, and predicted when it might go back for a third. If it does, this should make for an intriguing stellar light show.

For babies born with a certain heart defect, implantation of a "shunt" is essential to their survival. A new type of shunt can be expanded using light after it's been implanted, potentially eliminating the need for more heart surgeries down the road.

Honeybee Robotics has outlined a plan to build a kind of power grid on the Moon, with a network of Statue of Liberty-sized towers containing solar panels and batteries that provide power and communications, and even act as streetlights.

It's ironic that in places where drinking water needs to be checked for microbes the most, labs that can perform the analysis are least likely to be present. A new "lensless" device could help, as it uses light to detect harmful microorganisms.
