Position of flask on magnetic stirrers can drastically affect reproducibility of experiments Comprehensive examination reveals improper siting of reaction vessels can affect catalyst formation, alter nanoparticle formation and change yields

New research shows that simply changing how a reaction vessel is positioned on a magnetic stirrer can significantly change a reaction's speed and product quality, influencing the reproducibility of results. #ChemSky #ScienceSky #EduSky

Epigenetic editors enter clinical trials New wave of precision medicines amplify or silence genes, without altering genetic code

Epi editors change the activity of individual genes without altering genetic code, and could help treat many diseases. To learn more, I spoke with scientists from four companies at the cutting edge of this entirely new type of medicine 🧪 #chemsky

Mercury-free electrochemical lithium isotope separation could fuel a fusion future Vanadium oxide pores selectively sequester sieve lithium isotopes

The new approach uses a porous vanadium oxide compound that acts as an isotope-sensitive filter, sequestering the lighter lithium-6 isotope while allowing lithium-7 to pass through faster. #ChemSky

I think it's important to reach out to your own community and explain what the funding cuts mean in practice.

The Tumultuous Birth of Quantum Mechanics The creation of modern quantum mechanics was a messy business in which many of the participants did not grasp the significance of their own discoveries.

To mark the launch of the International Year of Quantum Science and Technology today, I wrote this historical piece for the APS.

James Fraser Stoddart obituary: chemist and nanotechnology pioneer who built molecular machines An early love of construction toys led the Scottish chemist to thread molecules together, opening up a new field of chemistry.

Thanks for spotting that!

Computer simulations shed light on how material can shrink when heated New theory offers insights into the origin of the very low and negative thermal expansion observed in cordierite

When heated, cordierite shows very little overall expansion and negative thermal expansion along one direction. New molecular and lattice dynamics simulations are helping us understand why.

‘Stamp out paper mills’ — science sleuths on how to fight fake research A group of scientists who are experts at spotting fraudulent research outline five essential steps to combat industrialized scientific misconduct.

I'm delighted to share our opinion on #papermills published in Nature. Science is flooded with papers from paper mills.Certain steps can be taken, but this is a challenge that neither universities nor journals are ready to face.Some use paper mills to their advantage.

Today we report a new compendium of human gut microbiomes with >168,000 samples

By analyzing this massive dataset, we discovered distinct microbiome patterns across the globe, and show we can predict where a person lives just from their gut bacteria

Now out in Cell:

Finland downgrades MDPI and Frontiers – will others follow suit? Decision to downgrade 271 journals on quality and operating model concerns sparks debate

At the same time, Finland is downgrading several MDPI journals to its lowest rating. These two headlines couldn’t be more different.
