Presently, orthopedic surgeons use screwed-in metal plates to hold unstable broken bones together. There may soon be a less problematic, more customizable alternative, though, which incorporates a light-cured composite material.

Scientists at Sweden's KTH Royal Institute of Technology have produced a completely renewable version of see-through wood thanks to the addition of a fruit peel extract, which also happens to make it more translucent than previous versions.

Disposable diapers are not eco-friendly, not only because of their plastic outer shell, but also due to their petroleum-based absorbent inner layer. There could soon be a sustainable alternative to the latter, though, and it's made from wheat gluten.

However useful a drug may be, it’s a problem if it has adverse effects on healthy cells. Now researchers have shown a way to keep drugs on target, by wrapping them in a transport that can only be unlocked by a certain RNA sequence unique to cancer.

Heating and cooling systems are huge consumers of energy, so passively cooling buildings and electronics could help the environment. A new photonic film could be just the ticket, made with a micro-structure inspired by a beetle that likes it hot.

Although we have seen "morphing" structural materials before, they typically incorporate solenoids, pumps or motors. Now, however, scientists have developed a carbon fiber composite that shifts shape with a simple shot of electricity.

Scientists at Sweden's KTH Royal Institute of Technology have developed a new film they say can be layered over the top of solar cells to capture infrared light, boosting their efficiency by as much as 25 percent.

A new way of bending X-rays raises the prospect of smaller, more powerful X-ray space telescopes. Based on technology originally developed for medical imaging machines, the new design replaces conventional mirrors with a network of micro-engineered plastic prisms.

Wearable health-monitors are everywhere, from Fitbits for the health conscious to continuous glucose monitors for diabetics, but most are limited in what they can tell us, and there are issues around accuracy, calibration and reliability. Researchers in Sweden are working to change that.

Three years ago, we heard how scientists from Sweden's KTH Royal Institute of Technology had created transparent wood – it could serve as a cheaper alternative to the silica-based glass used in windows and solar cells. Now, the material is additionally able to store heat and later release it.

​Given that they're applied to items such as furniture and home insulation, it would really be best if flame-retardant coatings didn't emit toxic fumes. That's why scientists from Texas A and M University have developed a non-toxic alternative, made from natural renewable materials.

​In an effort to spare diabetics the pain of performing daily finger-prick blood glucose tests, various groups have developed continuous blood-sugar monitoring systems. Swedish scientists now believe that they may have improved on such technology, utilizing a skin patch that sports a tiny needle.
