The discovery could provide a natural alternative to artificial colourants, and a solution to the long-standing blue dye challenge facing the food industry.

The sensor functions based on colour-changing gold nanoparticles, which reflect infrared light when an infrared reader is used.

Researchers have developed a biodegradable plastic derived from organic fish waste that would otherwise be thrown away.

An Israeli company is using kenaf, along with hemp, to derive materials such as thermal insulating plaster, masonry blocks and walls.

Researchers have developed a device that can harvest daylight and relay it to underground spaces, reducing the energy cost of lighting them up.

The cable that holds the drone in place provides connectivity as well as power.

A simple manufacturing process generates biomass-based plastics from the wood powder typically found at lumber mills.

The water produced from the device has a freshwater purity of 95 per cent, and so is able to increase production of crops such as rice and wheat.

Using solar power to split water molecules creates hydrogen without the vast amount of usual carbon dioxide emissions.

Engineers have developed a way to turn polyethylene into wearable fabric with a low environmental footprint.

When combined with water, the fire suppressant cuts the amount of time and water needed to extinguish peat fires by 40 per cent.

Researchers have developed a way to use wood to generate electricity via a chemical process that removes lignin from wood cells.
