Researchers have shown that it is possible to train artificial neural networks directly on an optical chip. The significant breakthrough demonstrates that an optical circuit can perform a critical function of an electron...

A new study reveals a single neuron is capable of encoding information from two different sounds by switching between signals associated with one sound to that of the other.

A new study reports when certain brain areas react more strongly to food rewards than financial rewards, children are more likely to overeat, even if they are not hungry or overweight.

Did DNA analysis of an "alien" mummy violate legal and ethical boundaries?

Nothing accelerates technological innovation like cash. Lots and lots of cash. More bucks means more Buck Rogers. More cash means more people building, experimenting, failing, and eventually driving breakthroughs. In Dec...

A GREAT deal rides on the accuracy of the gene-editing tool known as CRISPR-Cas9. Since its discovery in 2012 it has become popular for tinkering with genomes of all kinds, thanks to its ability to make editing cheap and...

IN DECEMBER 1989 Guido van Rossum, a Dutch computer scientist, set himself a Christmas project. Irked by shortcomings in other programming languages, he wanted to build his own. His principles were simple. First, it shou...
