Windows will soon generate electricity, following solar cell breakthrough

Two square metres of solar window will do the same job as a standard rooftop solar panel, Australian researchers say.

Semi-transparent solar cells that can be incorporated into window glass are a “game-changer” that could transform architecture, urban planning and electricity generation, Australian scientists say in a paper in Nano Energy.

The researchers – led by Professor Jacek Jasieniak from the ARC Centre of Excellence in Exciton Science (Exciton Science) and Monash University – have succeeded in producing next-gen perovskite solar cells that generate electricity while allowing light to pass through. They are now investigating how the new technology could be built into commercial products with Viridian Glass, Australia’s largest glass manufacturer.

Cold War nuclear bomb tests reveal true age of whale sharks

The radioactive legacy of the arms race solves a mystery about the world’s largest fish.

Atomic bomb tests conducted during the Cold War have helped scientists for the first time correctly determine the age of whale sharks.

The discovery, published in the journal Frontiers in Marine Science, will help ensure the survival of the species – the largest fish in the world – which is classified as endangered.
