Essential Science: Transparent wood can transmit light

Technologists have developed a transparent wood that has grabbed attention as a future material for green construction. The material is also remarkably energy efficient, in terms of its ability to release heat, thereby lowering energy costs.

Electron tunneling for new light emitting devices

San Diego - Researchers have applied solution-based chemical synthesis techniques in order to improve light emitting devices. The new technique could assist with the development of more advanced electronic devices.

Controlling the speed limit of smart technology gadgets

Understanding why there is a speed limit on how fast the properties of light can be changed is the way forward for the next generation of consumer electronics including smart watches, screens and glasses, according to new research.

A boost for graphene-based light detectors

Graphene functions as a light-sensitive material, which makes it suitable for light detectors. These devices can offer significant improvements over current materials presenting future possibilities for optics.

Physicists create new form of light

Physicists have demonstrated that photons can be made to interact with each other, creating what is, in effect, a new form of light. This development could help with the creation of quantum computers.

Dim light makes us dimmer

Michigan - As research questions go, it's an interesting on: "Does dim light make us dumber?" By this researcher have studied the effects of spending too long in dimly lit rooms on brain structure and memory.

Pulses of light to protect cryptocurrencies

Technologists have successfully used pulses of light to encrypt data. This technology could be used to protect the security of cryptocurrencies.

Daylight saving connected with stroke risk

A new study suggests that turning the clocks backwards and forwards, to match the changing seasons, affects the internal body clock to the extent there is a possibility of the risk of stroke.

Street lights linked with poor sleep pattern

There are various causes of insomnia, ranging from stress and worry, to social habits like the use of e-readers. However, there could be another reason — street lighting.

Developers of 'original night mode' app f.lux respond to iOS 9.3

A new feature in Apple's latest iOS update, iOS 9.3,made headlines this week. Night Mode automatically shifts the brightness and temperature of the display to reduce blue light at night. It is similar to established app f.lux, recently blocked on iOS.

Essential Science: Why some rainbows are completely red

Rainbows containing only a limited fraction of the light spectrum can form. This happens as the sun drops lower in the sky. New research has found the presence of rainbows that are primarily red.

How nanoparticles can magically change colours of stained glass

A new process for linking metal nanoparticles could lead to new color displays made of light-scattering nanoparticles. The process will allow the user to switch colors by flicking a switch.

'Li-Fi' could be coming soon — Wireless 100x faster than Wi-Fi

Developments in wireless networking over the past few years have seen Wi-Fi become faster and more reliable than ever. It's still far from perfect though, and now new tech known as 'Li-Fi' threatens to supersede it, boasting 100 times greater performance.

Super accurate stopwatch made from graphene

Dresden - In a new application of the "super material" graphene, researchers have used ultra-thin flakes of graphene to construct a very fast and very accurate stopwatch.

Shining a light on global development

This year is the International Year of Light and Light-Based Technologies, backed by the United Nations. The objective is to raise global awareness of the social, economic and developmental role of light and optical technologies.

MIT's new camera sensor could erradicate photo overexposure

Researchers at the Massachusetts Institute of Technology are working on a new way of capturing light with camera sensors that could put an end to overexposure in photos without having to enable HDR or alter the shot in post-processing.

Ant cooling mechanism avoids desert sun

Ants found in the Sahara have a novel way of keeping cool from the intensity of the sun’s rays. The small, silver-colored hairs on the ant’s body are able to reflect heat back, stopping the insect from becoming too hot.

Scientists overcome the major issue of large fibre optic networks

Scientists have discovered a way to keep data moving at high speeds over very long fibre optic networks by preventing the signals from weakening. It removes a key limitation of fibre today and could make future networks faster and significantly cheaper.

Bring the sun into your home with the Silk smart lightbulb

A new smart LED lightbulb aims to improve your health, wellness and sleep patterns by providing you with light that is more akin to that of the sun. It slowly shifts from blue to red in the day, allowing your body's circadian rhythm to operate normally.

World's thinnest ever light bulb produced

By taking advantages of the properties of graphene, scientists have created the thinnest light bulb ever. The bulb is the size of a silicon chip.

Researchers develop light-emitting paper for flexible displays

Chinese researchers have successfully created a sheet of light-emitting, transparent and flexible paper with a new eco-friendly manufacturing technique. The paper could be used to create truly flexible displays for bendable gadgets of the future.

Mystery deepens over light spots on surface of dwarf planet Ceres

The mystery of the two strange light spots on the surface of the dwarf planet Ceres has deepened. New infrared images from the Dawn space craft are giving contradictory information, which has left scientists baffled.

Gold nanoparticles used for unique energy storage

Scientists have devised a way to capture and store energy using gold nanoparticles. This is by using gold atoms at a level just below gold metal. The findings could help with future medical instruments.

New traffic light tech reduces congestion by turning lights green

A new device fitted to the windows of cars that is being trialled in the UK aims to reduce traffic congestion and pollution in city streets by enabling vehicles to turn traffic lights green as they approach.

LG G4 to have a 5.5-inch, extra bright QHD display

LG has released details of the display that is likely to be used on its upcoming G4 Android flagship smartphone. The 5.5-inch unit looks set to be one of the best displays ever fitted to a phone with exceptional brightness and contrast improvements.

Graphene light bulb headed for shops, cuts energy use by 10%

The first commercially viable consumer product to be built from graphene is to go on sale before the end of the year. The dimmable light bulb will use 10% less energy than other bulbs but will last longer because of graphene's increased conductivity.

Scientists find new way to control light for next gen computing

Scientists have created a device reminiscent of a bee's honeycomb that can twist beams of light around tighter curves than has ever been witnessed before. This could become a powerful way of transmitting data on circuit boards in next gen computers.

Windows 10 for phones to include notification LED support

New leaked screenshots of an unreleased build of Windows 10 for Phones revealed last night that the operating system will feature support for notification LEDs. Just a day later, such an LED has been found hidden inside Microsoft's Lumia 735.
