Truly green paper battery is algae-powered

The batteries that power our everyday devices, from laptop computers, to mobile phones, watches, toys and flashlights, are a major source of pollution. The average household in the Western world uses about 20 batteries a year, resulting in hundreds of thousands of tons of discarded batteries that end up in landfills. When the battery casing corrodes, toxic heavy metals like mercury and cadmium can leak out and pollute soil and ground water.

A spotless record

The sun has gone quiet

IT IS almost exactly 400 years since Galileo turned his telescope on the sun and saw it to be an imperfect orb covered in spots, quite unlike the teachings of Greek cosmology. If his observations had been made four centuries later, he would have drawn a different conclusion. The sun has recently shed its spots, prompting sceptics to renew their claims that climate change is not anthropogenic but rather heliogenic.

Fighting it out

Can a computer be programmed to be cunning yet fallible?

IF A computer could fool a person into thinking that he were interacting with another person rather than a machine, then it could be classified as having artificial intelligence. That, at least, was the test proposed in 1950 by Alan Turing, a British mathematician. Turing envisaged a typed exchange between machine and person, so that a genuine conversation could happen without the much harder problem of voice emulation having to be addressed.
