Another prop for Moore’s Law has appeared. An international science team has built a diode from a single molecule, making the component nearly 1000 times smaller than its current equivalents found in computer processors – which means hardware and gadgets can carry on shrinking as well.

As a child, Ronald Mallett wanted to travel back in time to try to prevent his father’s death, and hence went on to study physics. Despite now believing that the present cannot be affected by meddling with the past, he has announced his intention to build a ‘time machine’ based around circulating laser beams, using equations based on Einstein’s work on realtivity. The project is in need of financial backers, but he reckons he can have the desktop device made and ready to confirm (or falsify) his theory within a decade. Stop giggling at the back.

Chevy’s decided to get all “viral” on us by recruiting users to mix advertisements for its new Chevy Tahoe. Thing is, there’s nothing saying the ads have to be complimentary. (The linked ads are kind of lame — but the concept’s worth a giggle.)

There’s nothing like inflammatory rhetoric to get the blood flowing, but holocaust doesn’t actually seem such an inappropriate term to describe widespread deaths of coral reefs in the Caribbean and Indian and Pacific oceans. In the Caribbean, sustained record water temperatures weakened the coral, and a disease called “the white plague” dealt the death blow.
