How much exercise do you really need?

In contrast to the video I made on exercise, I also spoke to a researcher about how our brain makes it rewarding to put in a lot of effort! When you work hard, you get a reward. But how does your brain now you've been working hard? They looked at the mechanism which you can hear about here:

Why do lot thing, when few do trick? I've got a new film on the surprising benefits of little exercise presented once again by @lizziegibney.bsky.social. Based on a Feature by @marilenharo.bsky.social, it looks at emerging data from smart devices. Also I dress as an 80s man. youtu.be/jskktKzWfys

I stopped putting protein powder in my breakfast after making this video (with producer & extra extraordinaire @nickpetrichowe.bsky.social) It's based on this great story by @marilenharo.bsky.social from the end of last year🧪 www.nature.com/articles/d41... Do you need more protein? Watch & learn!

Watch this video if you want to: A) Find out how much protein you actually need 🍗 B) You want to see me dress up as a German Chemist from the 1840s 🧪 C) You're a fan of @lizziegibney.bsky.social's amazing presentation style 💃 D) All of the above

Funky shape changing molecules can change colour too! A cool advance inspired by octopuses.

Where I talk about an ancient mysterious boat and a preserved fingerprint...

Given the responses to the science songs we made, I'm casually adding 'musical director' to my CV.

all this is both foolish and unnecessary

Time for another science carol! 🎄 Some researchers stuck a duck to a rock, so we sang a song about it. As you do!

'Tis the season for some festive science songs. If you've ever wanted to hear someone sing about a dimunitive tyranosaur then now is your chance

In a gear change from my last few stories...by acting as a "mechanical fuse" this simple little slipknot, added to surgical thread, can radically improve how surgeons perform sutures & lead to better outcomes A lovely intersection of mechanics, geometry and medicine 🧪 www.nature.com/articles/d41...

Did you know there's lightning on Mars? There is! At least very small versions of it. AND YOU CAN HEAR IT. For more, check out my latest podcast for @nature.com

A very cool story by my colleague @lizziegibney.bsky.social about how some quirky physics of knots could help make surgery better!

About that exclusive, "closed-to-press" MAHA summit last week with RFK and JD Vance: I got in. Here's what I saw. 🧵 🧪 www.nature.com/articles/d41...

Do you wanna see a robot pick up a weird squishy bug? I may have just the video for you... youtu.be/FHW6eKvtcBw

Anyway, we need some joy, so here's the Egyptian foreign minister being given a Lego Pyramid by the Danish foreign minister.

Is Nanotyrannus a baby T. rex, or is it its own species? @shamini.bsky.social has been finding out!

Bowhead whales live a really long time! We may now know why. My latest for @nature.com

Nature is hiring a new Multimedia Editor, so if you want to work with me then this is a great opportunity. Who could say no to that? It's for verticals, so if you know your Toks from your Tiks, your ring lights from your Reels, and your shoots from your Shorts, then this might be the job for you!

Highly recommend, we're fun! Also a great chance to cover cool science.

Want some GOOD news, for once? This article will leave you feeling happy end positive about the future

I am honoured.

It's a very good moustache. You'll have to watch to see it.

No mice were devoured in the writing of this headline (or in this research for that matter).

Proof that climate change is real and horrible: www.bbc.com/news/article...

Fewer grad students means less science, but many STEM PhD programs in the US are cutting back on admissions this year due to federal funding uncertainties. Words by me for @nature.com: www.nature.com/articles/d41... @emsque.bsky.social @ucsdcooperlab.bsky.social @julieposselt.bsky.social 🧪

Astonishing when you see it like this.

Great new film from @nature.com youtu.be/BGT7kuaruZY?... @shamini.bsky.social and @nickpetrichowe.bsky.social knocked this one out of the park

Super close race in the technology Lovies category this year. Go and and give @nickpetrichowe.bsky.social a vote, and watch his excellent film on the AI surveillance pipeline while you're there vote.lovieawards.com/PublicVoting...

Here's a T. Rex bored to death trying to bite their own tail. My partner asked me to animate it in stop motion, after she watched a video about the very important topic of "could T. Rex chew its own tail like a dog". The puppet is still a work in progress 🦖

You've probably heard how a high percentage of #Nobel laureates are immigrants. The US in particular has benefited from the influx of bright minds. @jennaahart.bsky.social ran the data for this century's Nobel prizewinners — and shows more than 30% immigrated. 🧪 www.nature.com/articles/d41...

BREAKING: The Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret, and John M. Martinis "for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit" Stay tuned for more.

I may have found my defining quote. Pair this with my pinned post and you will see what I mean!

Really cool story - bird species from across the world make the same sound to warn against cuckoos, and they can even understand each other. Feeds into ideas Darwin had about the origin of language! www.newscientist.com/article/2498...

my gosh. truly an end of an era.

On National Poetry Day, the greatest poem I have ever read

I've been a bit rubbish at the ol' social media recently, as I've been making lots of cool things. A short thread.

This is just incredible. Someone made not just a computer, but an *entire working LLM* out of (438 million) minecraft blocks www.tomshardware.com/tech-industr...

I'm on @nature.com's podcast talking to @nickpetrichowe.bsky.social about the role that journalists can play in combating research misconduct. Honored to appear alongside @jamesheathers.bsky.social, @abalkina.bsky.social, @richvn.bsky.social and many others: www.nature.com/articles/d41...

I'm a deeply flawed individual, but I bring joy to the world.

Fusion energy has got a boost from some chemistry inspired by the controversial case of cold fusion! By using electrochemistry to trap deuterium in palladium, researchers boosted fusion rates by 15%. Hear about it here @nature.com www.nature.com/articles/d41...

Light-powered flying saucers, Victorian toys, and @danjfox.bsky.social animations. This video has it all! And they could help understand a weird part of the atmosphere known as the mesosphere, that's too thin for balloons and too heavy for satellites.

Me: I don't think I have much of an accent anymore. The internet:

So fun to be featured on this week’s @naturepodcast.bsky.social talking about the tree microbiome and could not be more thrilled to be following a story on rubber ducks.

If you're gonna test our your new sticky hydrogel then sticking a rubber duck to a rock must be in the top 10 best ways to do it.

I covered this on the podcast, but it really warrants seeing!

Researchers are trialling all sorts of inventive ways to root out errors. Scientists are human. So, sometimes mistakes slip through the cracks. To make science as robust as possible, though, they've created all sorts of methods to seal those cracks. I explore these in a new @nature.com podcast.
