🧵 As front-page headlines go, this has to be one of the most misleading I've seen in a long time It's an out-and-out lie But notice the trick they use to get away with it...👀 *They're* not lying - they're just quoting someone else who is👍🏻 In this case, the leader of the opposition🙄 1/33

Did you know the wasabi in most sushi restaurants isn't wasabi? Or that a chemical synergy between dried seaweed and raw fish enhances sushi's savoury flavours? Learn more about sushi science with this infographic, as requested by my sushi-mad seven-year-old 🍣 wp.me/s4aPLT-sushi #ChemSky 🧪
This infographic titled "Sushi chemistry: nori, wasabi and sticky rice" explores the science behind sushi. It features three main panels with illustrations, chemical structures, and explanations. The left section explains how amylopectin in rice creates stickiness and how acetic acid from vinegar aids gelatinisation. The middle panel covers umami flavours from glutamate, inosinate, and guanylate found in nori and raw fish, displaying their molecular structures. The right panel discusses allyl isothiocyanate in wasabi and horseradish, along with gingerol and shogaol compounds in pickled ginger (gari). Photos of six different sushi rolls line the bottom.

Working on an A.I. policy for my calculus classes. Decided to be upfront about the current situation with LLMs and to give a heartfelt explanation for why the course still matters.
Al policy

Context

Artificial Intelligence, or "A.l.," Is a broad term used to refer to several different kinds of technologies. The kind most relevant to this class are Large Language Models (LLMs), which use mathematics to analyze large amounts of human-produced text and then generate new text that simulates what a human might write in response to prompts or questions. Some examples of LLMs are OpenAl's ChatGPT, Anthropic's Claude, and Google's Gemini.Current LLMs can provide a solution to any calculus problem I give you. So why should we work on them, you might ask? Here's the thing: for the most part, the problems were already solved anyway. Calculus as a subject is nearly 400 years old. It has reached into virtually every modern scientific and economic field. And while I would like to believe that I have crafted a few new problems with some small amount of originality tailored to this class, for the most part I have curated a collection of exercises drawn from my years of teaching calculus. Those exercises come from textbooks, workshops, friends, and other fields of study, as well as my own invention.
And they nearly all have known solutions, often with fairly standard approaches.
Before A.I. became widely available, you could find those solutions in another textbook, or from a friend's notes, or through a repository on the internet.The point of this class is not necessarily to solve problems that have never been solved before. It is for you to develop habits of thinking that are used by mathematicians, scientists, and policymakers-to develop a sort of mental toolbox that can be applied to new problems. If along the way you happen to find a new way of solving one of the class exercises, that's great! I am constantly learning new things from my students. But you will be bereft of discovery if you rely on a LLM for solutions to the calculus problems before you. Here I mean the discovery of having your own realizations, crystallizing your own internal understanding, claiming the knowledge in a way that cannot be taken away from you.
That ownership is what I want for you, and that is what the course is built around.

In case you missed it: @chemicalscience.rsc.org now charges an APC of £2,850 per paper. It was previously free (diamond OA), and in my view it contributed greatly to the appeal and success of Chem Sci. Sad to see the RSC go that way…
For submissions from 1 July 2026 an APC will apply to all articles accepted in Chemical Science. Use our journal finder to check if your APC is covered by an institutional agreement with us. Note, if your institution has an agreement with us that covers APCs, you will be notified of this at article acceptance. Details of the APC and discounted rates are found here.

Get your manuscript submission ready with our submission checker tool. You can instantly check against Chemical Science's guidelines and requirements, and receive helpful hints to get you ready to submit.

Yes it could be argued that keeping up with world events is important but alternatively can I interest you in hugging an ancient mossy boulder that looks like a face and quietly listening while it tells you stories from centuries cloaked in mist.
A lovely mossy boulder with a face. I walked past this venerable stone gentleman on Dartmoor when I was beginning to write my first novel, Villager, and it whispered all 104,000 words of the book to me. So now I have to pay it all of my royalties. Unfortunately my ex-publisher stopped paying me royalties last year. Understandable, the boulder was not happy. But now I have a new publisher and the book has been republished. So remember if you purchase a copy you will be helping a boulder to eat, pay the rent on his riverside moss garden, and feed his boulder family.
