Some disturbing posts and behaviour being seen on this site recently. Don’t let what happened to Twitter happen here.

Report and block.

I won’t engage with such nonsense.

She explained to her husband, who was there to help host the event, that she knew me when I was a “bay doctor”. He thought she meant I was a neonatologist back then. But no, she very very junior 👶🩺🍼

Quite simply, the disinformation spread by RFK Jr and his fellow charlatan’s will hurt more and more children until the burden of misery cannot be ignored by the policy / lawmakers - and the electorate that empowers them.

Enjoyed talking with the Papworth Mesothelioma Social Group (patients, families, carers) about some of our most recent mesothelioma discoveries

Lovely to catch up with the great Lavinia Magee who was a senior meso nurse at @royalpapworth.bsky.social when I was a trainee

Whoops Apocalypse, 1986

An Iranian leader falls, world powers blunder, Russia threatens

A Labour gov faces an aggressively posturing US administration

I’m really not sure why this 1980s political comedy, in which the world nearly ends by mistake, came to mind

Diversity should be a strength. We think differently, behave uniquely, contribute individually

But populists target difference. They identify a small, weak group—they wouldn’t pick on strong billionaires—and encourage the majority first to fear, then to hate them

Don’t be manipulated by populism

Her work was v important. She used her chemistry knowledge to alter the pharmacokinetics (PK = how the body handles a drug) of chaulmoogra oil, which was available for leprosy but limited by its PK. We still don’t know how the oil works, but her advance was to turn it into water‑soluble ethyl esters

Researchers praise ‘stunning’ results of new prostate cancer treatment Early trials of the drug VIR-5500 showed it shrinking tumours in some patients

VIR‑5500 shows strong activity in advanced prostate cancer in phase 1 trial with minimal toxicity. Many showed tumour shrinkage, incl. complete resolution of liver mets in one case. Not yet peer‑reviewed; larger trials planned.

One of my lovely PhD students has a place medical school in the US after she finished here. As a thank you for helping her prepare for interviews* she had this mug made with my favourite NHS quote on it

*I would say she got in _despite_ my help. I can’t believe my lefty views would have helped her😆

A welcome U-turn

Hopefully a sign RFK’s antivaccine faction is being marginalised

FDA political appointee Prasad had first overruled FDA scientists. Then POTUS reported to have pressured FDA Commissioner Makary. Next, FDA agreed to review the application

A lot of people, including me, were wondering how an IRB could ever approve this study.

The answer is that no IRB did. The person who “signed off” on approval from the only ethics board that reviewed it had resigned three years earlier. His signature was used without his knowledge.

All the pupils were terrific

It can be nerve wracking to give a scientific talk to a packed room of fellow students and some university professors

Here they’re getting certificates from Julian Rayner, our head of department

School pupils Noor and Zarah spent a few days in our lab at @thecimr.bsky.social over half-term as part of the ISAC/M programme. Their mini projects had them studying cellular senescence & antitrypsin polymerisation respectively

Their talks at @stcatharines.bsky.social today did us proud 🥹🔬🧬

It’s part of a series of actions the agency has taken under Secretary Robert F. Kennedy ...

The webpage warning chlorine dioxide & raw camel milk are NOT cures for autism (they can kill you) has disappeared, courtesy of 🧠🪱 & co.

The throughline of flipping facts, & cozying up to quack cures persists; this all makes Americans less safe & less healthy.

🆕 We’re excited to announce the launch of a new government campaign urging parents and guardians to get their little ones vaccinated to protect against serious illnesses such as measles.
