#Lipids are fatty #molecules that play critical roles in cell function, including membrane structure, energy storage and nutrient absorption. Most lipids are made in a cell #organelle called the #endoplasmic reticulum, but specific lipid types are shuttled around to different parts of the cell depending on their purpose.

We are headed into the season of the Nobel Prize. Announcements of awards will begin on October 6, with the Physics Prize being announced on the 7th. This year, I decided to have some fun in the “fediverse” and try to tease some nuggets out of the wisdom of the crowd.

While crowds are, in fact, not always wise, it is nonetheless fun to use some of the tools of the open social web to prompt […]

Every Molecule Matters by Simon Cotton, 2025

Every Molecule Matters is a successor to the author’s earlier Every Molecule Tells a Story and tells the story of a wide range of molecules.

These range from the familiar odours that enhance the pleasure of eating (and the spices that add piquancy) to the vitamins vital to our survival, as well as the ways in which insects and plants use chemicals to protect themselves.

There’s controversy surrounding the compounds of chlorine, which encompass life‐supporting anaesthetics and natural antibiotics, as well as insecticides like DDT, which saved innumerable lives but became an environmental cause célèbre. Through the addictive power of nicotine, smoking tobacco transformed from a curiosity imported from the Americas into a megapound industry that has caused significant human illness and death. And how safe is vaping? Discover the painkillers that have become drugs of abuse, and smile at the smelly sulfur compounds that serve as unpleasant human odorants (and defence molecules for skunks), control natural cycles in the environment or act as flavourings in wine. You will discover them all here.
This book showcases the structures of hundreds of compounds used by humans, animals and plants. Some are beneficial; some are not. Find out here why you should be better informed about them.• This collection of molecules includes human issues, such as the chemistry of vaping, and drugs of abuse, including ‘spice’, nitazenes and fentanyl.• ‘Chemistry of Everyday’ includes vitamins and the molecules that give foods their aromas and appetizing appeal.• The chemistry of nature ‐ how plants and insects use chemicals to defend themselves against potential predators, whether humans, birds, animals or other insects.• Organohalogen compounds, encompassing the atmosphere-damaging CFCs and their replacements...

Oh, look! 💩 An article that's basically "Sewers: the new #gold mines?" As if Victor Hugo's wisdom-strewn pipes weren't enough, now Calum's here to convince us to excavate them for "vital #molecules." 🚽🧬 Because clearly, going down the drain is the future, folks!

« […] l’humanité aurait contracté une dette de toxicité du fait de l’accumulation de plastiques dans notre #environnement. Car en se dégradant progressivement sous l’effet du temps, ces minuscules débris relarguent des #molécules #chimiques et parviennent de plus en plus facilement à pénétrer à l’intérieur des tissus des #organismes vivants […] »

Глубокое обучение для квантовой химии. Часть II. Предсказание электронной плотности

Всем привет! На связи снова Константин Ушенин из AIRI, и мы продолжаем говорить о глубоком обучении в квантовой химии. В прошлом посте мы немного разобрались в том, что такое молекула, как её представлять в компьютере, и как работают графовые нейронные сети. В этот же раз я расскажу о том, какие результаты в этой области получила наша команда. Речь пойдет о новой архитектуре для предсказания электронной плотности LAGNet, про которую у нас недавно вышла статья в Journal of Cheminformatics [1] . Мы применили несколько интересных усовершенствований к модели DeepDFT, что позволило в 8 раз снизить требование к объёму необходимых данных и в целом сделало выучивание плотности более эффективным. Но обо всём по порядку.
