Also, if you're "in bed with flu", it's almost certainly Covid.

After a long pause, I've just done another England Covid & NHS update as we head into the autumn/winter season.

TLDR: we're in a significant Covid wave now, the NHS is stretched, get boosted if you're eligible.

Waning immunity. A significant Covid wave in England. No new variant.
Thanks Prof Pagel for highlighting and contextualizing

New #ScienceSignaling experiments in mice show how the enzyme SPEG prevents the leakage of calcium ions in skeletal muscle cells—a finding that could inform research into diseases associated with mutations in the calcium-releasing channel RYR1. https://scim.ag/3KKfpEG
Phosphorylation of RYR1 at Ser2902 decreases Ca2+ leak in skeletal muscle and susceptibility to malignant hyperthermia and heat stroke
Reducing Ca2+ leak through mutant RYR1 prevents pathological heat production in skeletal muscle.

Die deutsche Blick auf Grossbritannien ist von jeher durch Mythen, Kitsch und Sentimentalitäten verstellt. Auch deshalb weil die Engländer sich gerne selbst so sehen.
Die Realität sieht ein wenig anders aus.

Bluesky, I am pleased to present to you the main product of postdoc work, published in @science.org ☝️

As it turns out, the very quality control mechanism that can remove mutant mtDNA copies is the one that maintains high mutant burden, or heteroplasmy levels
High heteroplasmy decreases mitochondrial ubiquitination

How can mitophagy be an effective quality control mechanism if mtDNA mutations reach high enough levels to cause disease?

This question led us into a dark path, full of concepts of evolutionary genetics, germline stem cell biology and mito-nuclear compatibility.

Ubiquitin-mediated mitophagy regulates the inheritance of mitochondrial DNA mutations
Mitochondrial synthesis of adenosine triphosphate is essential for eukaryotic life but is dependent on the cooperation of two genomes: nuclear and mitochondrial DNA (mtDNA). mtDNA mutates ~15 times as...

We got solar panels installed about a month ago, and we’re running at about 75% energy independence. In autumn. In Ireland. This is not some unsolvable quantum physics problem for god’s sake 🤦

~40% of the ENTIRE corn crop of the US is used to make ethanol. This gets blended with gasoline to power well under 10% of our vehicle miles. If we converted 100% of our vehicles to EVs installing solar on a small fraction of the land this corn is grown on would power them all.
US domestic corn use graph from 1980 to 2020. The orange bar representing "Alcohol for fuel use" (aka ethanol) starts growing in early 2000s, explodes before 2010 and stays huge through the graphs 2022 end. This explains most of the increased corn production in the US.

As an STV voter in both N & S Ireland I always felt my vote had more influence over the outcome, than in 30 years in (until 2024) a safe Tory seat in GB. (It also keeps out fringe parties that don’t reach a quota in any constituency, and keeps a constituency link to MPs unlike a list system)

Adoption of PR for all elections has to become Labour Govt's top "system change priority" and critical by 2027 OR TOO LATE.
Sadly too many want to put all their chips on red, blinded by once in a lifetime 2024 result.
Otherwise 33% will beat 55% under current FPTP in 2029.
Keep up great feed Sandy!

E.g. The Met Office is the nation’s weather service AND a global climate change research centre. It is highly vulnerable.

Ministers fund its research, influence its priorities, and appoint its leaders. With no statutory basis, its priorities and funding could be changed with little oversight. 5/11

We found that the UK’s top scientific institutions, from the Met Office to the UK Health Security Agency, have inadequate institutional defences.

If an incoming government wanted to weaken the role of science and evidence in policy making, it could do so shockingly fast. 2/11

🧵🚨

The UK’s independent scientific bodies are highly vulnerable to politicisation - over the past 5 months I've been working with @martinmckee.bsky.social to map out their vulnerabilities and it's not good news.

Today our report is published!

UK’s arm’s length public bodies are highly vulnerable to politicisation
Seven in ten Britons say it is important for top scientific institutions to be independent in exclusive new polling.

Good to see the Conservative Party committed to keeping the deficit down by *checks notes* spending £2 billion giving tax breaks for private education, creating a massive new deportation force and pledging to maintain pensioner benefits.
