Happy to lecture at the Institute for Studies of Science (ISoS) in Bielefeld. I will discuss how knowledge on the historical unfolding of chemistry turns fundamental to escape the dangers of the Anthropocene www.uni-bielefeld.de/zwe/isos/eve... #history #chemistry #Anthropocene

En este webinar hablaré sobre cómo diversas disciplinas pueden unirse para responder preguntas fundamentales para el futuro de la ciencia y la humanidad

Systematic attribution of heatwaves to the emissions of carbon majors - Nature Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

The former Soviet Union, China’s coal and cement industries, Saudi Aramco, Gazprom, ExxonMobil, Chevron, and several other companies are major contributors to the dramatic heatwaves www.nature.com/articles/s41... #climatechange

‘Alchemy still has a sort of cultural cachet; it just seems incredibly romantic’ In his latest book, award-winning science writer Philip Ball delves into alchemy and its place in the history of science and culture

I've long admired @philipcball.bsky.social's polished and prolific prose. It was great fun to talk to him about his new book on alchemy for @cenmag.bsky.social

‘Sex reversal’ is surprisingly common in birds, new study suggests Survey of five Australian avians finds numerous discordant individuals, including a genetically male bird that had laid an egg

An excellent biological example of how binary sex classifications can be problematic: a genetically male bird laid an egg. www.science.org/content/arti... #sex #biology

A real pleasure to share that I will start next year to do research at the Institute for Studies of Science at Bielefeld www.uni-bielefeld.de/zwe/isos/ through a research grant I got from the DFG #chemistry #sciencehistory #sciencesociology

Do ant colonies work like liquid brains? Check this great paper in @pnas.org led by @ceabcsic.bsky.social Pol Fernandez and F.Bartumeus that shows how to explain collective foraging by modelling ants as neural agents @jordipinero.bsky.social @frazambelli.bsky.social www.pnas.org/doi/10.1073/...

Industry and academic leaders urge UK government to recognise chemistry’s strategic importance Amid uncertainty in higher education, experts highlight subject's vital contributions

In the face of mounting financial pressures in higher education and industry, the UK government is being urged to take action to protect the chemical sciences. #ChemSky #ScienceSky

Excellent experience at S-DISCO Days in Gdańsk. Beyond the superb scientific programme, it was inspiring to witness the next generation of drug discovery scientists in action—what energy!

Bumble bees damage plant leaves and accelerate flower production when pollen is scarce Bumble bees manipulate plants to bring about earlier flowering.

Facing a scarcity of pollen, bumblebees will nibble on the leaves of flowerless plants, causing intentional damage in a way that speeds up the production of flowers, according to a Science study from 2020.

The Molecular Bond That Helps Secure Your Memories | Quanta Magazine How do memories last a lifetime when the molecules that form them turn over within days, weeks or months? An interaction between two proteins points to a molecular basis for memory.

Why can you still remember things that happened ages ago? You can thank a two-protein team in your brain.

A recent PNAS paper discusses the use of digital tools in historical research. I complemented the story by highlighting new questions that computational history enable us to ask (examples are provided). www.pnas.org/doi/10.1073/... #History #computers

How the Nobel Committee for Chemistry Has Shaped the Nobel Prize: Historical Trends Based on the Nobel Prize Nomination Archive The Nobel Prize in Chemistry is governed by the Nobel Foundation’s rules and managed by the Royal Swedish Academy of Sciences via its Nobel Committee for Chemistry. Despite 125 years of awarding these prizes and increased transparency from the Nobel Foundation, many aspects of the selection process remain obscure. Our analysis of the Nobel Prize Nomination Archive from 1901 to 1970 reveals that the decisions were heavily influenced by the personal and professional biases of the members of the Nobel Committee for Chemistry, who were not only responsible for inviting and assessing nominations but also for presenting recommendations to the Academy. Nobel laureates also significantly influenced the process due to their right to make ongoing nominations. The study suggests ways to improve the nomination and selection process to better reflect the evolving nature of chemistry in the 21st century.

The Nobel Committee for Chemistry has strongly shaped the outcome of the Nobel Prize in Chemistry, at least during its first 69 years. After all, it is an award that is difficult to decouple from our human biases and interests #chemistry #NobelPrize pubs.acs.org/doi/10.1021/...

Sulfenylcarbene-Mediated Carbon Atom Insertion for the Late-Stage Functionalization of N-Heterocycles Late-stage functionalization (LSF) is a crucial strategy in drug discovery, allowing the modification of complex molecules, including pharmaceuticals, to enhance chemical diversity in drug libraries. ...

A nice and clean methodology to add carbon atoms in the late stages of drug discovery processes. If widely adopted, this approach could significantly reduce the environmental impact of chemical research. #chemistry #drugdiscovery

AI drug development’s data problem The future of drug discovery may be artificial intelligence (AI), but its present is not. AI is in its infancy in the field. To help AI mature, developers need nonproprietary, open, large, high-qualit...

A recent Science paper www.science.org/doi/full/10.... discusses data challenges in AI-driven drug development. In an e-letter responding to the paper, I briefly complemented the authors by highlighting the importance of publishing negative results. #chemistry #drugdesign #AI

A nice piece by @chrisnsimms.bsky.social in the @newscientist.com featuring a few of my thoughts on fascinating new research uncovering forbidden electronic transitions — a development that could enhance atomic clocks and, in turn, our precise sense of time. #periodictable #chemistry #physics

It was a real pleasure. Thank you for reaching out, and congratulations on the excellent piece!

It would be very interesting to determine the minimal social 'circuit' that allows for cultural anticipation. Clues in that direction are addressed here for biological systems. Nice @ricardsole.bsky.social paper.
