Two new chapters from my free online book in human genetics out this weekend!
These complete Part 3 of the book, on human population structure and history:
3.3: Human prehistory [separate thread]
3.4: Ancient DNA: a genetic time capsule [this thread]

This went under the radar but answers a fundamental question in Epigenetics...

From many hundreds of olfactory receptor genes, each neuron selects expression of only single one (near-randomly). How?

Outstanding work from Mathieu Boulard and colleagues

The transcription of a single olfactory receptor per neuron is enforced by epigenetic silencing of their enhancers
The ability to discriminate thousands of odors in our environment requires each olfactory neuron to express a single olfactory receptor from hundreds of available genes. The biochemical mechanism enfo...

There are many concepts which are useful and important in helping us make sense of biology, but which do not correspond to something real at a fundamental level. Species exist in our books and papers, but biology doesn't know about them.

Great science thrives on sharing knowledge across borders, and the EMBL Sabbatical Fellowship Programme helps make that possible.

We're excited to host Natalie Twine from CSIRO. Learn about her time at EMBL-EBI and the Sabbatical Fellowship Programme👇
EMBL’s Sabbatical Fellowship Programme is slowly growing, attracting participants from around the world with its collaborative insights and access to world-class technologies.

Chemists out there - learning about point group symmetries from my son - what is the point of pint group symmetries? Given the computational modelling now available for Raman etc … is this needed. It is … cute

New result: you can build a universal computer using a single billiard ball on a carefully crafted table!

More precisely: you can create a computer that can run any program, using just a single point moving frictionlessly in a region of the plane and bouncing off the walls elastically.

On a Wensleydale pilgrimage - geographically and back in time - to where and when epidemiology was about fieldwork (or practice) amongst real people in actual populations, and involved literally crossing fields … check out his beautifully written papers as a seasonal treat to yourself …

This headline is wrong and misleading, and the brief text below it is not much better. Whatever might constitute a full explanation of the differences between sapiens and other hominins, we remain confident that 'genes' will be central to it.

Genes don’t explain what made humans different
Tiny genetic variations between humans, Neanderthals and Denisovans might not be all they were cracked up to be.

Dear UK Energy transition experts on bluesky - I read that by the end of this year there should be enough synchronous condensers for the last piece of grid services to allow fossil free operation - does anyone know if this is true? In the inevitable christmas demand dip is this likely? Or foolish?

It’s out! Using cryo-ET in Dicty cells, we take a fresh in situ look at vaults. Surprisingly, we uncover vaults associated with ER and NE membranes, and find that many vaults enclose ribosomes in defined orientations, opening new avenues to their cellular function! www.biorxiv.org/lookup/conte...

Vaults. They are cell biology's greatest puzzle! This preprint from Martin Beck's lab shows them docked on ER membranes with a ribosome inside. What on earth is going on there??

The eukaryotic vault particle is a giant ribonucleoprotein complex that assembles into an iconic barrel-like cage. Its cellular function has remained elusive despite extensive characterization. Using ...

I missed this the first time and lovely to see it published from Rob Finn's group and Toby Spribrille's group on the complicated (so complicated!) world of Lichens. They are complex communities which... are sort of a bit like species. (but not)

The Australians are fundamentally better at Cricket than the Brits (at least at the moment). Ashes away is harder for the visitors but there is too big a gap. Sigh. Lots of talk for next test for avoiding the whitewash

Just a reminder that Large Language Models is just one type of AI. It is not synonymous with AI and indeed the key aspects which make LLMs work - big attention networks, very large embedding spaces - have many applications.
