Is the molecule in the computer?

The Molecular Graphics and Modelling Society began life as the Molecular Graphics Society. It’s hard to imagine a time without computer graphics, but yes, it existed. The MGS was formed by the pioneers who made molecular graphics commonplace.

In 1994, the MGS organized an Art and Video Show (Goodsell et al., 1995), and I submitted some of my own work. One of the other images — inspired by Magritte‘s “Ceci n’est pas une pipe”, depicts a molecule with a remarkable similarity to a pipe — and to a molecule… It was submitted by Mike Hann (of GSK):

“Ceci n’est pas une molecule”, image by Mike Hann, 1994.

I Prompt, Therefore I Am: Is Artificial Intelligence the End of Human Thought? 

Welcome to a slightly different blog post than usual. Today I am sharing an insight into my life at Keble College, Oxford. I am the Chair of Cheese and Why?, which is a talk series we host in our common room during term. The format is simple: I provide cheese and wine, and a guest speaker provides the “why”—a short, thought-provoking talk to spark discussion for the evening.

To kick off the series, I opened with the question of artificial intelligence replacing human thought. I am sharing my spoken essay below. The aim of a Cheese and Why? talk is to generate questions rather than deliver answers, so I hope you’ll forgive me if what follows doesn’t quite adhere to the rigorous structure of a traditional Oxford humanities essay. For best reading, I recommend a glass of claret and a wedge of Stilton, to recreate the full Oxford common-room experience.

Nanobodies® galore in Utrecht

At the end of September, I had the opportunity to present at the 4th Single-Domain Antibody (sdAb/VHH) Conference hosted in the city of Utrecht. The sdAb conference is a biennial event, and was held for the first time in Bonn (2019), then in Brussels (2021) and Paris (2023), before coming to the Netherlands this year.

This was the first time I’d attended a VHH-focused conference, and I was taken aback at just how large the community is; the Jaarbeurs ‘Supernova’ event hall was completely sold out, with over 400 researchers in attendance (pictures below courtesy of the organisers). The buzz reflects the ever growing interest in sdAbs as tools to discover new fundamental biology, vectors for diagnosing disease, and as prophylactic or curative therapeutics. Most every disease indication was represented at the conference, from anticancer and antiviral sdAbs to antivenom sdAbs (both for use in lateral flow tests to diagnose the snake that bit you, and as quick ‘epipen’-like therapeutics accessible even in the most remote parts of the world).

Using Node-RED as a front-end to your software

Node-RED is an, open-source, visual programming tool that lets you wire together hardware (such as sensors), APIs (such as REST/POST) and custom functions. However, its custom functions aren’t simply the JavaScript you write, they can also be containers!

This can provide an intuitive front-end to otherwise difficult software. For example, you’ve written your magnum opus, you’ve even documented it (though no-one will ever read it) and to ensure maximum compatibility for the widest possible audience, you’ve containerised it. But it’s still a command-line driven application. Using node-RED you can make this accessible to an inexperienced audience.

Out of the box, node-RED’s quite pretty, you can string together nodes to perform functions that are useful. In this case, it’s for monitoring a log file, if the log doesn’t grow, something’s gone wrong, so email me to take a look at it.

Fragment-to-Lead Successes in 2023

Back in 2021, I highlighted the annual fragment-to-lead (F2L) success stories from 2019 [Blog post] [Paper]. This is one of my favourite annual publications, and I’m delighted to see that it’s still going strong. In this post, I’ll discuss the 2023 edition that was published in at the start of 2025 [Paper].

Are you addicted to dopamine? 

Ever since the pandemic my attachment to screens and media has slowly crept up on me, and I suspect that’s the case for many of us. It hit me when I started panicked after leaving my flat without headphones, thinking “how could I ever walk around with just my thoughts?” I decided to significantly reduce my technology usage and I keep getting the sense that I’m experiencing some kind of withdrawal from the constant media and dopamine hits, but I was curious just what’s going on, and how bad it is. 

What does dopamine actually do and is “dopamine addiction” scientifically accurate?

Human Learning in the age of Machine Learning

Source: Venus Krier

Oxford University has recently announced that its students will receive free access to a professional-level subscription of ChatGPT Education. This decision is more than just a perk, it’s a signal. One of the world’s leading universities is openly acknowledging that generative AI will be central to the academic experience of its students. But what does this mean for learning? For education? For scholarship itself?

To frame this question, it is worth beginning with a macro view: Mary Meeker’s AI Trends Report (2025) argues that AI is accelerating the transformation of knowledge work, pushing tasks once reserved for experts into more automated or semi-automated regimes. In her framing, AI is less a standalone innovation than a “meta-technology” that amplifies other domains.
