The catch is, as with practically all "healthy food", that you need to squint at a certain way at very carefully selected data and interpretations to make it look beneficial. The moment you look for evidence for actual health benefits under realistic conditions it all turns into marketing smoke. 🧪

On day six, when circling behind the moon, the Artemis II crew will be further away from the rest of mankind than anyone ever before. Living the dream!

This falls under "Ask AI only things where you already know what the answer looks like."

Wow! 🤩

Love this image of astronaut Christina Koch in the Orion spacecraft looking back at Earth, especially the floating braids. 👩‍🔬 ⚛️ 🔭 🧪 🚀 🌔

How anybody can look at this image and think there are better options out there is entirely beyond me. The only planet with whales, and butterflies, and giant sequoias. Home.

The Martian Moons eXploration spacecraft has arrived at the Tanegashima Space Center! This was a TOP SECRET operation due to concerns that someone might steal MMX and head to Phobos 🤫🛰️ Although I do wonder if the truck could’ve been a shade more… covert... 🔭 JAXA 🧪🔗: www.isas.jaxa.jp/en/topics/00...

Lab Leakers: "SARS-CoV-2 can't infect bats, so it must have been made in a lab". Science: "Let's do the experiment". SARS-CoV-2 behaves exactly like one would expect in a reservoir species - low-level infection, no overt disease, etc. Elegant study from Sato Lab: www.biorxiv.org/content/10.6...

Toblerone chemistry actually is more complex than you might imagine...

Over at Mastodon I just learned that the most important part of a keto diet is toblerone. #chemsky 🧪

Pope Leo XIV has a degree in mathematics from Villanova university. To get where he is he has had to demonstrate a sound knowledge of original sin, but he will be the first pope to completely grasp original cos and original tan.

An abbreviation (ABB) in a journal article (JA) or Grant Application (GA) is rarely worth the words it saves. Every ABB requires cognitive resources (CR) and at my age by the time I'm halfway through a JA or GA I no longer have the CR to remember what your ABB stood for.

Today I learned that there is a deep-sea bacterium that apparently can do photosynthesis independent of the sun. It uses infrared light from hot hydrothermal vents. www.pnas.org/doi/10.1073/...

Today I wrote a short article about all the other goods that passed the Strait of Hormuz. Ir's not all about oil and gas. The gulf region is also an industrial hub that provides massive amounts of processed goods. There's LPG and diesel, for example, or sulfur and Helium. 1/

Many strange theories bouncing around about SARS-COV-2 BA.3.2. Many make claims about it preferentially infecting young children..... some come up with wild theories why. True? Probably not. 1/6

TIL: At least seven American airports are named after people who died in plane crashes. 😅 via @theatlantic.com

I have to correct myself: we are homotopic with a donut only when we have a really bad cold. Which also proves that viruses can change even our mathematical properties. Scary!

Mathematically speaking, eating a Donut is cannibalism.

This one made me actually lol: inpreparation.substack.com/p/jen-heemst...

There's talk of a very strong »Super El Niño« percolating throgh the media right now. I'm a bit unhappy about the reporting there, though. There are two issues that get little if any mention. One is that predictions right now are super uncertain. We are in a prediction gap. 1/

Viele Frauen hier haben intensiv die gestrige Diskussion verfolgt und mitgestaltet. Ich wundere mich ja immer noch, dass sich hier so viele wundern. Was mich besonders verwundert hat, ist die Verwunderung vieler Männer hier über folgende Tatsachen: 🧵 #Ulmen

Am 18. März macht der Weltrecyclingtag darauf aufmerksam, wie wichtig Recycling für Ressourcenschonung und Klimaschutz ist. PFAS sprengen dieses Erfolgsnarrativ: Sie wandern mit durch die Stoffkreisläufe. pfas-dilemma.info/aktuelles/10... #pfas #weltrecyceltag @fischblog.bsky.social

I have a joke about reaction kinetics but I lack the energy to start.

In case you missed it @elda-miramontes.bsky.social's new paper shows (with phenomenal imaging) how waves propagating within the water column (internal waves) shape the seafloor below the surface. 🧪🌊

Ein Planet, auf dem Menschen leben können - oder soll man es lassen? Trotz jahrelanger Medienkritik und verheerenden Auswirkungen auf öffentliche Debatte und Demokratie: Wer sich für eine fundierte Analyse mit diesem neuen Pro und Contra Meinungsstück interessiert, wird hier fündig. Ein Thread:

If you ask someone today to name the builder of Hadrian's Wall, they would give you a funny look. But historical memory is odd, and right up to the 1800s we forgot who built it. Until in 1840 John Hodgson, an obscure Northumbrian clergyman, published the LONGEST footnote in history... 1/22

There seem to be quite a lot of people who strongly believe that AI is smarter than they are. They are probably right.

March 11 marks the 15th anniversary of the 3rd-largest seismic event ever recorded, the magnitude 9.1 Tōhoku earthquake and tsunami. Recovery from this devastating event is still ongoing. Research into ways to make our society more resilient to nature's unpredictability continues.

Weil die EU nun mehr Atomkraft fordert und insbesondere Mini-Reaktoren fördern will: Es gibt da ein paar Probleme. Etwa extrem hohe Kosten, gerissene Zeitpläne, fehlende Investoren, Müll... meine Analyse für @zeit.de www.zeit.de/wirtschaft/2...

Yes, I keep repeating myself, but the term 'superfood' is still a reliable red flag for poor and misleading reporting. 🙄 There's a lot of dodgy food science and even more dodgy food reporting, but superfood stuff is consistently among the worst. No, I won't link to the latest offender.

Ich versteh das richtig, ja? Die CDU ist total empört, dass Özdemir nicht eigenhändig dem Hagel vor dem Wahlkampf den Mund zugenäht hat?

The connection between oxygen, carbon dioxide and sulfur is really fascinating. And I never heard about it until 10 minutes ago. #climate

Es ist total wichtig, sich immer wieder zu fragen: weiß ich wirklich, was ich zu wissen glaube? Die meisten Dinge wissen wir nur so ungefähr. Das ist ganz normal. Anderes Beispiel: was macht eigentlich eine Zentralbank? Klar, in etwa weiß man das. Aber könntet ihr es erklären? Ich spontan nicht.

OK, dann macht doch mal den Selbsttest: Wie funktioniert er denn, der #Treibhauseffekt? 😁 #Hagel Hint: es ist komplizierter als man denkt. Hier die Erklärung.

It's true that women's football often is a lot more likable and at times less cringe than the men's game. But it's still the same FIFA. You know, the one with the peace prize and the faint whiff of corruption you can smell from a mile off.

AI will replace people with radioactive wastelands. Oh well, on the positive side, a lot of people get to say "told you so" one last time.. www.newscientist.com/article/2516...

I'm feeling old... During the 2+4 negotiations, the big issue was precisely that everyone was uncomfortably aware the answer to this has generally been a resounding yes.

If there is one book that fits our times like no other, it's Stanislav Lem's Star Diaries.

If this goes on long enough we will eventually evolve not to trust statistical autocomplete software with medical decisions.

Welcome to the FAFOcene. www.theguardian.com/world/2026/f...

It's worth remembering that Europe had nearly 8000 cases in 2025. And about 33000 in 2024. Without proper vaccine coverage numbers can get very large very quickly.

Storytime! Recently at the office: So I came across this press release. It was about structural color in an unusual golden textile made from mussel byssus. I regularly write science news, and this one has everything: chemistry, gold, history and a physics effect most people never heard of. 1/

I don't think you all realise how amazing south east asian tectonics actually is. 😍 ⚒️ (yes, it's about the Borneo quake)
