I’m an award-winning mathematician. Trump just cut my funding. The “Mozart of Math” tried to stay out of politics. Then it came for his research.

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...

Morphine analogues kill pain with fewer negative side effects Redesign of the potent painkiller's core prevents breathing suppression and reduces addiction-related behaviours in mice

A simple skeletal edit produces a morphine analogue that kills pain but has fewer negative side effects.

Enough of the billionaires and their big tech. ‘Frugal tech’ will build us all a better world | Eleanor Drage Titans like Musk would love us to believe innovation means top-down solutions that only enrich the wealthy. In fact, we all have the power, says Eleanor Drage, research fellow at Cambridge University

This is well worth a read.
Some glad someone is championing that most impactful technology is cheap and easily obtainable.

"Physics writes equations, humanities talk about emotions. But the world is one” says Carlo Rovelli.
Sean Carroll's Bayesian approach relies on computer scientist and philosopher Judea Pearl's breakthrough that taught AI systems to distinguish correlation from causation.

I was explaining to my Ukrainian colleague the phrase ‘There’s no such thing as a free lunch’. She told me the equivalent in Ukrainian is ‘The only free cheese is in the mousetrap’ - which is so much better

Getting good at human tasks 'What do you mean you had to lock the NMR with an oscilloscope and shim the magnet by hand?'

Just as scientists no longer have to spend time shimming NMR magnets or inserting samples by hand, thanks to autoshim routines and autosamplers, one day we will look back at the things we do by hand now and marvel at how far we've come. #ChemSky #ScienceSky

Best flight ever !! 😂🐕

The Phage Collection Project will be at the #SummerScience Exhibition this coming week, visit the Royal Society to find out more about the world of phages and play your part to tackle antimicrobial resistance: www.phage-collection.org

Wonderful event, great to see and interact with so many amazing talented technicians and the rest of the @ucl.ac.uk community.
Also gained a new appreciation for how nice a setting UCL East has in the Olympic park.

Part one of today's UCL Open Day. Big crowds. very busy. We have six demonstration stations to talk about ocean acidification and carbon dioxide, fluorescence, magnetism and superconductivity, use of microwaves in synthesis, and the smells of organic compounds.
Fun for all the family. #chemistry

Andy Stewart and Luna Jiang pictured, but the stand was showcasing #electronmicroscopy work from UCL faculties of Life Sciences, Brain Sciences, Medical Sciences, Engineering, MAPS and Social and Historical Sciences.

Royal Society prize winner returns award in protest over Elon Musk Andrea Sella is latest scientist to express dismay over UK science academy’s refusal to criticise tech billionaire

Amazing colleague performing amazing acts while others are too afraid to act or speak.

This tiny device can shrink dangerous blood clots. It’s called the ‘milli-spinner’ and its invention was partly an accident…

Andrea’s principled stand reveals once again the failure of @royalsociety.org to stand by its own principles. They really have misjudged to moment – and the momentousness of Musk’s damage to the fabric of US science.

While diving into this beautiful topic is important to remember that ADPs are neither 'thermal parameters' nor 'thermal ellipsoids' (as implied in the acronym ORTEP): they model displacements in the averaged structure without discriminating between thermal and static contributions #crystallography

Another great day in Erice. I encourage all crystallographers and those wishing to learn about crystallography to attend a course here.

UK government announces 10-year budgets for R&D Policy details to be announced at next spending review

The UK government has announced plans to set 10-year budgets for R&D funding. It is hoped the new approach will provide long-term certainty for UK scientists and industry to enable them to tackle key challenges such as antimicrobial resistance.

Campaign launched to get Lego periodic table playset out there Spanish scientist wants people to vote for his spiral table to get Lego to bring it to life

Heinrich Baumhauer’s 3D periodic table from 1870 may soon come to life as a Lego playset, if a Spanish scientist's 'Periodic Tower of Elements' bid comes to fruition. #ChemSky
