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/...

"You cannot not communicate". Paul Watzlawick.

Highlights that all human interactions, even silence, are forms of communication and convey a message. Everything we do —or don't do — can be interpreted as communication by others. E.g. ghosting. There's no way out of being social.

Dear Reviewer #2, thank you for accepting to assess our revisions. After 60 days, the editor gave up, you never answered. The 1st author worked day & night to address your points, but you were too busy to even say no. The outcome is irrelevant, his disillusion isn't.

Review responsibly, it matters.

Success in academia often has more to do with luck, patronage and the job market than “hard work”.
Good academics acknowledge this.
I worked hard, but I was in the right place at the right time on occasion. Historians far more talented than I have fallen between the cracks.

75 days now of complete blockade/siege of Gaza. People are starving, babies elderly & sick already dying. Meanwhile Israel destroying what's left of Gaza so the living will have no place to return to. An atrocity for the ages and the world is so quiet.

🎉 Excited to share that our paper on FCDII is out today! 🙌🏻 Huge thanks to @sbaulac.bsky.social and @sara baldassari for bringing me on board and introducing me to the complexity of somatic mutations. Hope our work helps advance understanding of the disease mechanisms.

Shared Neural Codes for Emotion Recognition in Emoji and Human Faces
Facial expressions are critical social signals, essential for human communication. This study used EEG to investigate the neural dynamics of the processing of emotional expressions in real and emoji faces, using a data-driven approach. Across two experiments with identical paradigms, two separate sets of participants viewed facial expressions (happy, angry, sad, neutral) in real faces (4 female and 4 male identities, n = 24) or emojis (6 platforms, n = 25) while performing a two-alternative forced-choice emotion recognition task. Time-resolved multivariate classification and spatio-temporal searchlight analyses revealed robust decoding of emotional expressions within and across experiments. Consistent effects emerged early and peaked between 145-160 ms over posterior-occipital and parietal regions. Notably, robust cross-classification between real and emoji faces demonstrated that face-like emoji stimuli evoke neural responses comparable to those elicited by real faces, with more sustained effects over right posterior sites. These findings suggest that the brain uses overlapping spatio-temporal codes for naturalistic and symbolic facial expressions, providing new insights into the neural coding of social signals and the representational overlap between natural and artificial emotional expressions. ### Competing Interest Statement The authors have declared no competing interest.

Interesting study on cell-type-specific aging using single-nuclei transcriptomics in the human neocortex. Not clear to me based on this graph that pace of aging is striking different across cell types.

There are no ASD or ALS genes. Just like there are no ASD or ALS patients.
There are genes associated with these diseases, and people with them.
It's beyond semantics; it's about pleiotropy (genes) & individuality (patients). Denying complexity doesn't make a problem simpler to solve (tell POTUS).
