aptamer sensors patched up My astrobiology co-author Kevin Plaxco has been pioneering the development of biosensors based on aptamers (the artificially generated DNA equivalent of antibodies) for many years now and every once in a while I write about the progress in this fascinating field. Now the work has reached its first clinical trial, so I wrote a news story for Chemistry World to help spread the word. The news story is out now: World first for clinical trial of skin patch to monitor therapeutic drugs in real time Chemistry World 5.2.2026 Source: © Marsilea A Booth et al/Springer Nature America 2026 Previous episodes in this serie are listed here.

Our ChemRxiv article keeps moving; thanks #ChemistryWorld for covering the debate. Critics say it’s “too early” for conclusions, yet mixing principles are grounded in 100+ years of science. Read and make up your own mind.

Here is our @chemrxiv.org article: chemrxiv.org/engage/chemr...

carbon ring hooked up I don't write about real chemistry very often these days, but it's always great to hear about the creative (supra)molecular architectures and new allotropes of carbon developed in Harry Anderson's lab here in Oxford. The latest news from his lab, published in Science magazine this week, is the first molecular carbon ring stable enough to be investigated in solution by normal spectroscopy methods. Previous carbon rings were produced by atom manipulation on solid surfaces, a method requiring extremely low temperatures (see here and here). I wrote a news story for Chemistry World about this new work, which is out now: Ring of pure carbon stabilised by its catenane connections Chemistry World 15.8.2025 I believe it is freely accessible as long as you haven't used up your monthly quota of free articles from CW. The three macrocycles helped to stabilise the C48 molecule, allowing the first isolation in solution of this class of molecule. Image source: © Yueze Gao et al 2025

Some bacteria and archaea make nitrous oxide during ammonia oxidation to nitrite in well-oxygenated waters, whereas denitrifying bacteria produce it during reduction of nitrate in oxygen-poor waters. None of these, however, could fully explain the observed increase. ‘It was just this weird conundrum that in many cases the mechanism that was being used to explain most of these emissions didn’t seem to be there,’ says Jennifer Glass at the Georgia Institute of Technology in Atlanta, US.

Scott Wankel of Woods Hole Oceanographic Institute in Massachusetts believes that the ‘exciting’ findings could solve a key mystery: ‘For a long time we’ve known that whatever nitrous oxide was getting out into the atmosphere was made in the upper [ocean] layer, and we thought that was nitrification by ammonia-oxidising bacteria and archaea – but they don’t like light,’ he says. ‘Here all you need is for the upper metre of seawater to have some organic matter in it, and the nitrous oxide will be quickly released to the atmosphere … it really could be driving the entire bus of the oceanic flux of nitrous oxide to the atmosphere, or at least a very large part of it.’

I am truly amazed by the reception our discovery has received in the scientific community 🥰🥰🥰
