Angela Rayner accidentally pays less tax than she should have, resigns, and the media gives her hell.

Nigel Farage deliberately pays less tax than he should have, and the media gives him a free pass.

That, right there, is the problem.

It was interesting to talk with Darren Orf recently about the opportunities and challenges of wireless power beaming. www.popularmechanics.com/science/ener...
Wireless Electricity Is on the Horizon—And It Could ‘Beam’ Power Right to Your House
Power beaming could allow an orbiting space-based power station to deliver one gigawatt of solar power, enough to power about 1 million homes annually.

Withdraw the state visit invitation to Trump.

Offer one to Zelensky instead. With bells and fucking whistles.

I think this is the closest many of us have ever got to seeing the real Trump. The only consistent thread in his entire unhinged rant was the love & praise for Vladimir Putin. Zelensky has more courage & dignity in his little finger than every member of Trump's regime & fan club combined.

Great article on th risks inherent in US Scientific Institutions staying quiet in the face of Trump's assaults on EDI. Please read. 👇
I have run out of patience with the apparent silence of most US science institutions (and not just US) in the face of Trump & Musk's rampage. There are of so many facets of that, but in this column for @chemistryworld.com I talk about the assaults on inclusion.

Scientific institutions have a long history of anticipatory obedience
Societies should learn from this and speak up to support inclusion

Many congratulations to Aidas Baltušis who successfully defended his PhD thesis: “Developing a Time-resolved Photoluminescence imaging system using a compressed sensing approach.” Many thanks to the National Physical Laboratory (NPL) and EPSRC for supporting his project.

If you’d asked AI to write a piece of Russian propaganda in the style of Donald Trump, this is what you’d get. Well done America, you’ve elected a Russian asset as your President.

The world's richest man - perhaps the richest man who has ever lived - gloating about shutting down aid for the world's poorest people. All while posing as the champion of the common man.

The great lie of populism in its most naked and morally putrid form.
