Cell-extrinsic controls over neocortical neuron fate and diversity Cell-extrinsic cues are key for neocortical cell identity and diversity.

Ever wondered how robust cellular identity is to external perturbations? Here we disrupt cellular environmnent in vivo and in vitro, and find cell population specific sensitivities. Environment sculpts development yes, but not all cells are made of the same wood. www.science.org/doi/10.1126/...

Arctic glaciers face ‘terminal’ decline as microbes accelerate ice melt Scientists in Svalbard in race to study polar microbes as global heating threatens fragile glacial ecosystems

Interesting, well-written article from the Guardian.

Music to my ears. This is brilliant. Either 90% of us can claim to be better musicians than Beethoven or… maybe just maybe polygenic scores aren’t perfect?

Multigenerational cell tracking of DNA replication and heritable DNA damage - Nature A multigenerational single-cell tracking approach provides a framework to dissect phenotypic plasticity at the single-cell level, offering insights into cellular processes that may resemble early events during cancer development.

This ancient pathogen became deadlier when humans started wearing wool Ancient genomes reveal that a bacterial fever jumped from human-borne ticks to lice around the time wool textiles became common.

I never thought about wool as a possible route of infection.

On parle souvent de l'importance de la fluidité automobile au centre-ville. Pourtant, seuls 21% des déplacements vers le centre-ville se font en voiture. On devrait plutôt parler de comment améliorer le transport collectif (55%) et actif (23%) si on veut attirer les clients et travailleurs au c-v.

I’ll take it as a compliment today ☺️ maybe this retinol cream is working 😅

Getting mistaken for a student at my final exam ✅

Should I have pretended and write my own exam? 😁

This morning, teaching an undergraduate class in population genetics gave me hope and confidence for the future, those students are rocking it!!

Thanks your post made me realize how much I needed to hear that today ☺️

To the women in science. To the allies in science. To the ones who lift each other up.

I spend my life in science, constantly trying to figure out where I fit in. At times, it feels like pushing against an invisible force-one that questions, doubts, resists. But through it all, I am never alone. 🧵

Cephalopod sex determination and its ancient evolutionary origin Coffing et al. assemble a chromosome-level octopus genome assembly, revealing that the female octopus has just one sex chromosome (ZO karyotype), and males have two (ZZ karyotype). They conduct genomi...

Sex determination in cephalopods: hemizygosity (ZO) in females and ZZ males, and predates the radiation of the group 480 milions years ago. Fascinating work by Andrew Kern lab!

Our blood tests are interpreted by average reference values. That's missing a lot of rich information!
Each person has their own tightly regulated setpoints. One healthy person's complete blood count setpoint can be differentiated from 98% of other healthy adults.

that DeLorean though!

Would love to be included 😊

LoF and duplications correlated effects on phenotypes lead to an interesting paradox:

Predictive gene expression signature diagnoses neonatal sepsis before clinical presentation Despite appearing healthy at birth, neonates who later developed EOS already had distinct whole blood gene expression changes at birth, which enabled the development of a 4-gene predictive signature f...

Every year, >200K newborns die from sepsis.
Our team used machine learning to develop a set of genes that can predict neonatal sepsis risk using at birth blood samples.

Oh the answer key would be great indeed!

Awe thanks! Hope to cross paths soon again!
