Eco-friendly plastic crystals take the gas out of refrigeration

Scientists led by the University of Cambridge have developed a way to replace the organic gases used in most conventional refrigerators with plastic crystals. By using crystals of neopentyl glycol under pressure, it may be possible to build safer, greener, and more efficient cooling systems.

Portable ECG is aimed to be hands – or feet – above others

We've already seen a few portable electrocardiographs that let users monitor the electrical activity of their heart, wherever they may be. Researchers from Spain have just developed a system of their own, however, which offers something that most others don't.

Scientists get more mileage out of discarded tires

When we hear about tires being recycled, it's usually their latex content and/or their steel fibers that are being harvested. They also contain fabric, which hasn't been nearly as useful. That may now be changing, however, as scientists have created a building material using tire fabric.
