I was shocked to read the @irishtimes.com report on the biased judgment of Judge o’Donohue this morning www.irishtimes.com/crime-law/co...
His hypocrisy outlined by @irishcycle.com ⬇️ on top of the lack of objectivity is unbelievable

This is the saddest day of my professional life.
Today is not only the final recording of the latest series of The Infinite Monkey Cage, it is my last ever Monkey Cage.
I never thought that I would have to leave the show. I always imagined going on until | dropped dead under the studio lights due to a brain aneurysm caused by my final attempt to understand notions of quantum gravity or the shock of being told about fly maggot infestations in the sacks of macaque monkeys.
I resigned in September, after sixteen years of dedication to the show,
A show that I named and helped develop over all those years.
Unfortunately, my opinions outside the BBC have been considered problematic for sometime, whether it has been voicing support for the trans community, criticism of Donald Trump, numerous other outlandish opinions, including once gently criticising Stephen Fry.
These things were considered to conflict with being a freelance BBC science presenter

In a recent meeting where BBC Studio executives again voiced problems with me, I realised my choices.
Obedience and being quieter to remain making Monkey Cage, or 'Resign and have the freedom to speak out against what I believe are injustices'.
•
I chose the latter.
It broke my heart.
I love this show and I love the audience, and it is because of the audience in particular, that this decision was so difficult to make.
I kept thinking about all the extremist voices promoting hate and division. They are being given so many platforms, while voices that represent kindness, open mindedness, empathy seem to be scarcer and scarcer.
I felt I couldn't pamper myself with the luxury of silence.
One of my many privileges is that I am able to resign and I can speak out even if it is to the detriment of my career.

I have thought a lot about my heroes, Sinead O Connor, James Baldwin, Audre Lorde, and so many more.
I think of Sinead's words, "the job of an artist is to be themselves at any cost".
James Baldwin said prejudice was really just a word for cowardice.
Audre Lorde, viewing her life, wrote that her only regrets were her silences.
I think of my father as I resign, he brought me up to believe in fairness , justice and kindness.
Though my heart is broken, it is also full of fire.
I apologise to our incredible listeners for my departure, your love of the show means a great deal.
I am so sorry to let you down.
I hope that you can understand my reasoning.
I have to accept that I am not what the current
BBC expects of their freelance presenters.

Despite this I should add that I have always worked far more than my contracted hours to try and ensure the show was always the best it could be, as well as making myself accessible and responsive to the audience wherever and whenever I met them. Every night, we have recorded, I have been filled with determination to make the best show possible. This was not
"just a job"
I hope that with my departure I can be a better ally to the LGBTQ community, to the neurodivergent community, to activists fighting against those who aim to brutalise society, to those currently in prison on hunger strike, and to all those who fight for a more inclusive world.
From many conversations, I know there are many Monkey Cage listeners who support these communities and activists too.
The strawberry is dead.

Very sad that I felt I had no choice but to resign from The Infinite Monkey Cage - a victory for the transphobes and other bigots - I did it because so much of the media has chosen to believe the kind and empathetic people are a fiction - they are real and so often unrepresented.

A fantastic revelation of an additional, inadvertent, positive impact of vaccine:

“…older adults (aged 79–80) who had received the shingles vaccine were 20% less likely to develop dementia by 2020, compared to those who hadn’t been eligible to receive it.”

Health Covid raised risk of heart issues in children more than vaccination

A recent study of 14 million children in England reported in the @newscientistnl.bsky.social shows children that were vaccinated against Covid had a two-fold *lower* risk of myocarditis than after Covid infection. There was also reduced risk of inflammatory conditions such as Kawasaki syndrome 🧪

I find it really hard to believe that that charlatan in Killaloe is still on the go
Over 20 years ago, he requested a massive fee to treat a friend with a brain tumour that would’ve required a house re-mortgage.
He has absolutely no scruples.

Landscape format in ink line, watercolours and other water media on mixed media paper. View of terrace of single-storey cottages from inside a park showing grass lawn in foreground and a scots pine tree at both the left and right edges, rendered in dark greens, blues and purples, and a little brown, with sparse dark green foliage. Between them is a small baby leafless brown tree and behind the trees we see through black railings to the houses. Each cottage has a Georgian door with a fanlight above and a single narrow window to its side. From left to right the doors are red, black, grey, lilac, and blue, and each of them is up a set of stairs so we can see the top of a basement below. Their slate roofs are rendered in blue with cream chimneys that have orange pots. Sky is left blank white. A white car and a black car are parked in the right half of the picture on the road in front of the houses facing right. Signed bottom right in black ink, Liam Daly

#painting "Harold's Cross" was done on location as the sun was setting and my hands getting colder. I'd sketched in town earlier that day then cycled around Dublin 6 and its impressive houses before sitting in the tiny sliver of a park I'd always wanted to go to. #ArtYear #SpeirGhorm #UrbanSketching

The Global Sumud Flotilla is showing the world the effectiveness of strategic nonviolent activism in forcing a political crisis over Israel's genocide in Gaza. They are putting Israel in a corner and forcing states to get involved. These brave people deserve our full attention, solidarity & support.

The reason I'm concerned about Maria Steen being on the ballot isn't that she will win (she won't).

My worry is that if she is nominated, it will mean a month of national airtime for a hate campaign against vulnerable groups, carried by a media too scared of being sued to call it what it is
