Cow Tools! We have lived alongside cows for nearly 10,000 years. We breed them and exploit them It is now, only now, that we have discovered THEY CAN USE TOOLS Here I describe our study (paper) www.sciencedirect.com/science/arti... in @currentbiology.bsky.social with @auersperga.bsky.social

“Uruguay did what most nations still call impossible: it built a power grid that runs almost entirely on renewables—at half the cost of fossil fuels. The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”

I love adding "Happy new year!" to emails in January. Even, or perhaps especially, this year with all kinds of strange and dark stuff going on in the big world out there.

Wednesday, even. Your Wednesday. 🙄

So how's your Tuesday going? I started mine out by knocking an entire urn of coffee over when trying to wheel a trolley a bit closer to my course participants. 5L of coffee all over the nice wooden floor. My frozen smile:

Well, the cold windy season has arrived in Aarhus, but that can't kill the warmth inside of being PROMOTED TO FULL PROFESSOR in Epidemiology from November 1st 2025 🥳🍀 Thank you to all you lovely colleagues, collaborators, and mentors who have been so important throughout 💚 @au.dk

One for you @felixthehauskat.bsky.social 💀

These missions' weakness is that many struggle to articulate how strategies for tackling societal issues will directly translate into urgent, immediate GHG reduction, or how they'll double the effect tomorrow. GHGs have a time value: 1 ton/year displaced today is far better than next year.

yeah we're into LLMs (Large Lamb-bridge Models)

🤔 Have you ever wondered "What do we actually know about legume consumption and liver/gallbladder health?" 🫘👩‍⚕️ No? Well, we did because we found some old reviews and animal studies that hypothesized better liver health would be at the expense of more gallstones. 1/3 academic.oup.com/nutritionrev...

hoping that when they say the LLM talks like a Ph.D.-level expert, they mean "holds indecipherable decades-long academic grudges expressed largely in the form of questions that are actually more of a comment"

Can Bluesky say every word in the dictionary? I dunno but I plan to find out! I made a website that tracks every single word said on bluesky (as of yesterday).

Some cities run on solar 95% of the time – cheaper than coal. With falling battery prices (-40% in a year), solar can run almost 24/7 in the sunniest cities. And 60% of the time in cloudy ones. This isn’t theory. It’s already happening. @carbonbrief.org

Jeg har strikket til mine døtre. DESVÆRRE har Sigrid (hende med hættetrøjen) mistet sin på baren Osborne på Nørrebro i København i fredags. Hun vil blive mega glad (og også moren, der så ikke skal strikke en ny 😌) hvis den dukker op igen. Vil I dele?

Happy days just before summer break! Two PhD students have had papers accepted on our work with sustainable diets and health! 🥳🥳 Stay tuned for more information...

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

✨️The application deadline has been extended to July 1st. ✨️ Open to all PhD students and junior researchers with an interest in nutritional epidemiology.

Looking lovely this evening, @au.dk

I min Claus Meyer Almanak fra 2010 står der "Hylden blomstrer fra sankthans og 2-3 uger frem". I dag har jeg sagt til mine drenge at hvis vi skal ud og sanke hyldeblomster, skal det være nu, for dem på vores eget træ er toppet. #klimaændringer

This thread really resonates with my anecdotal experiences with my 13 year old son, who I really really want to be like the reader I was as a child, and who absolutely adored Wimpy Kid and Captain Underpants. When he finds a novel that grabs him, he swallows it raw. But finding him that book...🥲

Cycling isn't just transport. It's a daily dose of movement that can improve cardiovascular fitness and support mental health. Investing in bike lanes keeps cyclists safe and supports active, healthy communities. #MedSky #EpiSky #AcademicSky

Congratulations to Christian Antoniussen for the excellent oral defense of his PhD thesis, "Longitudinal measures of alcohol consumption throughout adulthood and the risk of invasive breast cancer among postmenopausal women" last week! 🎉

Thinking of my dear mentor Kim Overvad, sadly recently deceased, as I comment manuscripts with "this is a proportion, not a rate" and "higher or lower risk when comparing two groups, not increased and decreased". #EpiSky

Do parental BMI and socioeconomic position interact in children's growth? Children with greater parental BMI had steeper BMI growth than peers, regardless of family SEP or social mobility. @christinadahm.bsky.social

I finally found a strategy that’s dramatically reducing greenhouse gas emissions from food, and it’s a hilariously simple strategy. I wrote about it for @canarymedia.com. www.canarymedia.com/articles/foo...
