We work on humans with @antoniocbscosta.bsky.social @marcoromanato.bsky.social @wyartlab.bsky.social predicting effects of #DBS in Parkinson's Disease patients. Yet, understanding cellular & circuit mechanisms underlying behaviour require model organisms 🎏🐭🪱🪰 & cannot be done in humans nor organoids

Chronic back pain affects most of us eventually, and ageing discs are often to blame. But cellular senescence may not be irreversible.

This Insight Article explores how platelet-derived growth factors could help revive ageing disc cells.

Senescence: Returning aging cells to productivity

Platelet-derived growth factors can restore the proliferative potential of senescent cells taken from the degenerated intervertebral discs of aged humans.

Dear #izfc2025 participants, if anyone of you are interested in how transcription control defines mRNA fate and translation in zebrafish development, there are/will be several PhD and postdoctoral positions (funded by the Wellcome Trust) for this research. Please find me if interested.

NIH suspending or terminating grants with a very broad definition of dangerous gain of function research (which appears to include standard safe laboratory procedures)

www.science.org/content/arti...

Exclusive: NIH suspends dozens of pathogen studies over ‘gain-of-function’ concerns

Trump executive order leads to pauses on U.S.-funded research into TB, influenza, COVID-19, and other diseases, dismaying some scientists

V cool work from @ebriefer.bsky.social et al on how selection for sociability alters vocal signals (in sheep!) bit.ly/40AHKTd

1. Isolation but not feeding calls distinguish 🐑 selected for high vs low sociability

2. More selection for sociability ➡️ Less vocal individuality

#prattle 💬 #bioacoustics

Figure 1: Acoustic differences in isolation bleats (left side of panel) and in pre-feeding bleats (right side of panel) according to the ‘line’ (S+, S- and intermediate not selected when considering the isolation calls). A: Spectrogram of calls of one representative S+ female and one representative S- female according to the context of recording (FFT wl = 2048 pts, ov=90%, frequency sampling=44.1 kHz, amplitude range from blue to red color scale: -70 to 0dB). B: Averaged mean-spectrum (and standard deviation in shade) over the total amount of calls analyzed per line and contexts (Number of isolation calls: N=322 from S+, N=67 from S-, N=899 from not selected females; Number of pre-feeding calls: N=262 from S+, N=257 from S- females). C: Acoustic parameters explaining the Acoustic Score computed using a LDA on ‘line’ within
each context of recording (isoLD for isolation and pre-feedLD for pre-feeding). For isolation calls, the predictions of isoLD for calls recorded in non-selected females and comparisons (groups with different letters illustrate statistical differences, see supplementary statistical tables S3 for model estimates and pairwise comparisons).

Introducing warpfield, an open source Python library for GPU-accelerated non-rigid 3D registration. Warps and aligns gigavoxel volumes within seconds (not hours). For 3D microscopy, region-to-region and cell-to-cell matching.

It took us many years to improve idtracker.ai in both accuracy and tracking time. Here it is.
