Synthesis of (V0.2Cr0.8)2(Ga0.5Ge0.5)(C0.6N0.4), a Triple-Site Solid Solution MAX Phase MAX phases are an extremely versatile family of layered compounds that usually consist of an early to-mid transition metal (M-element), a main group element (mainly groups 13–15) or late transition me...

Quarter of UK university physics departments at risk of closing, survey finds Four out of five making staff cuts as physicists say findings are ‘great concern’ for UK’s leadership in important areas

This is really scary - I always thought physics was safe. It would be huge loss to see physics departments close across the country.

The SNSF urges against cuts In its statement on "Relief Package 27", the SNSF speaks out against the proposed annual cuts of 10 percent.

The Federal Council wants to cut costs in the ERI sector despite widespread objections. Cuts of over 10 percent per year are planned for the SNSF over the next few years. Above all, this plan jeopardises the innovation potential and competitiveness of the Swiss economy. ⤵️ www.snf.ch/en/9a7Fhnojt...

The SCS Fall Meeting 2025 has just been kicked off. Ready for a full day of interesting exchanges on chemistry in 🇨🇭 and beyond.

Computational discovery of novel oxide-based X-ray detectors at University of Birmingham on FindAPhD.com PhD Project - Computational discovery of novel oxide-based X-ray detectors at University of Birmingham, listed on FindAPhD.com

PLEASE REPOST: We have a 4-year, fully funded PhD studentship focussed on using computational chemistry to find new and improved oxides for X-ray detection, to start in October 2025. findaphd.com/phds/project.... This is open only to UK nationals.

New experiment uses levitated magnets to search for dark matter – Physics World Although it hasn’t detected dark matter yet, its developers say it offers an alternative path that is worth exploring

Two physicists from different disciplines met at a climate protest (as you do). They got to talking about their research (as you do). Within a year or so, they'd designed a new type of dark matter detector experiment (as you...wait, what?). First results here: 🧪⚛️ physicsworld.com/a/new-experi...

'Positive review only': Researchers hide AI prompts in papers Instructions in preprints from 14 universities highlight controversy on AI in peer review

My lab’s next paper is out in JACS!

Our electrode-orthogonal self-assembled layers can "self-heal" after degradation -- the key is a dynamic linkage we can molecularly tune! Hats off to Nico!

Breaking Kasha’s Rule to Enable Higher Reactivity in Photoredox Catalysis Nearly all photochemical transformations known to date follow Kasha’s rule, implying that reactions occur only from the lowest electronically excited state of a given spin multiplicity due to the fast...

We show how photoredox catalysis can bypass Kasha’s rule, enabling reactions from higher excited states.

This work, led by the exceptional @bjoernpfund.bsky.social, offers new insights into photochemical reactivity.

New Clue to How Matter Outlasted Antimatter at the Big Bang Is Found

CP violation, baryons, mesons, neutrinos, oh my!

America’s Brain Drain Could Become the World’s Brain Gain Research-funding cuts and immigration changes threaten some of America’s economic advantages.

The Atlantic's chilling secret: A century of data reveals ocean current collapse A century-old mystery of a stubborn cold patch in the North Atlantic is finally being unraveled. A new study links this anomaly to a long-term weakening of the Atlantic Meridional Overturning Circulat...

A study confirms what we have long argued: the spectacular Atlantic 'cold blob' is the result of a slowing of the Atlantic overturning circulation #AMOC, which transports warm waters into that region. That's the only part of Earth that resisted #globalwarming. 🌊

Keep this in mind when everything we do has to be PURPOSE driven. This is not how innovation works. It is often about curiosity. It can be silly.

Ocean Acidification: Another Planetary Boundary Crossed In this study, employing a detailed analysis of ocean carbonate system observations, models and biological assessments, we demonstrate that by year 2020, the average global ocean conditions had alrea....

Das hier ist die vielleicht wichtigste und doch wohl wenigst beachtete Nachricht des Tages. Eine weitere planetare Grenze ist überschritten. Wie üblich ist das Paper eher vorsichtig formuliert. Deshalb hier deutlicher: man muss über komplexe Systeme nur eines wissen: Ohne sie ist alles aus. Für uns.

🧪⚛️ There is a serious disagreement btw experiment and theory in understanding the ionization energy of a particularly excited state of helium. This is one to watch, though caution is always advised, as anomalies like this historically tend to go away. nanoscale.blogspot.com/2025/06/a-pr...

Plusieurs chapeaux représentant les rôles que les scientifiques peuvent jouer dans la société. L'Académie suisse des sciences naturelles (SCNAT) vient de publier un guide et de lancer un site web dédié à cette thématique.

🧢 Aujourd'hui, les scientifiques peuvent jongler entre différentes casquettes dans la #société. La @scnat.ch a mis en place un site internet pour inviter à la réflexion sur les différents #rôles qu'ils et elles devraient jouer ➡️ sciencesnaturelles.ch/roles_of_sci... #Science

"Google Scholar is manipulatable... we analyze over 1.6 million Google Scholar profiles and identify instances of citation manipulation to boost an author’s citation metrics. In many cases, this was done through a previously undocumented practice of 'citation purchasing' "

Graphs showing 25 years of budgets for the National Institute of Health, NASA, and the NSF. In all cases, the proposed budget for next year is far, far below any year of the previous quarter century.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
It's not just budgets but research, institutions, expertise, and training the next generation.
