Brilliant, inspirational, fascinating, inspiring, brain ageing shoot done. The Californian adventure wouldn’t have been half as much fun without the talented and delightful Ben Derico.

Bit of an effort to get a selfie with a squirrel. Just imagine filming with them. Was out with Fauna Bio in Emeryville California, finding out what humans can learn from 🐿️ hibernation.

How beer becomes leather, and much more tech, on this weekend’s @bbcclick. On the telly and BBC iPlayer this weekend.

Sometimes it’s important to remember what we built AI for. So much talk of risk and worry, but AI in healthcare is bringing phenomenal change. On ITV Lorraine this morning we talked colon cancer diagnosis as part of the No Butts campaign.

Will we be jetting off on hydrogen planes any time soon? I investigate on this week’s @bbcclick (great work from Yasmin Morgan-Griffiths behind the scenes - even making it look like I could throw a ball properly). bbc.co.uk/iplayer/episod…

When Bryan Johnson /dd pops you in the oven then starts pressing some buttons. And no, it’s not a sunbed. He suggested the infrared may be good for an energy boost. In reality I was filming, so was only in there long enough for my metal jumpsuit buttons to get rather hot!

A gold 3D printed model of my brain awaited me at my shoot at University of Southern California. Was there to discuss the latest research in brain ageing through imaging.

Back in California making a brain ageing documentary, also featuring some Bryan ageing (or not). Thanks Bryan Johnson /dd for the fascinating chat and experiments, brilliant fun as ever.

Today’s filming AI drug discovery at Ochre Bio. Many companies in this space, but what’s unique here is that it’s testing on actual human livers being kept “alive” in an “ICU” lab.

Busy start to the day talking AI (and Willy Wonka) on ITV Lorraine this morning, ahead of tomorrow night’s Wonka doc on Channel 5 where I look at how easy it is to create AI content.

Leather alternative made from the grain left over from brewing beer… today’s @bbcclick filming adventure.

Could hydrogen planes be the future of air travel? I’ve been to ZeroAvia to see how it’s been retrofitting and testing aircrafts for more sustainable travel.

Fascinating day spent LabGenius. Great conversation on the future of cancer treatment, and the role of machine learning and automation in drug discovery. Whilst results won’t come overnight, at least optimism lies ahead.

Best of luck Martin Lewis on your debut This Morning presenting this morning... you'll be brilliant, can't wait to watch!
