A couple of recent science interviews by me.

Optogenetics: it’s not just for tiny mammals any more. At least, not if a group from Rhode Island which wants to apply the technique to larger primates is right. A while back I asked them how easy that’s likely to prove. They also decided to examine whether the technique actually works as effectively as some believe; and it seems it really does.

Also: spotting Salmonella from its distinctive laser scattering signature isn’t a new idea, but a device able to analyse the bugs directly on agar plates could cut out a lot of awkward wet chemistry. And it can tell the difference between different strains of the pathogen, which turns out to be pretty critical. Plus it’s called Bardot, so there’s that too.
