Thanks, I thought host Lab was not a criteria as describe in the application note but I understand that some scientific strategy exist :-(
Good luck with oral presentation and the hard selection between all these smart candidates.

Sensation is dispensable for the maturation of the vestibulo-ocular reflex Vertebrates stabilize gaze using a neural circuit that transforms sensed instability into compensatory counterrotation of the eyes. Sensory feedback tunes this vestibulo-ocular reflex throughout life....

Big paper from @paigel.bsky.social in our lab:

Sensory feedback is always crucial for proper development, right? Wrong!

Crazier still, the motor system is the slowest part of a developing reflex circuit!

Interchromosomal contacts between regulatory regions trigger stable transgenerational epigenetic inheritance in Drosophila In some cases, non-genetic information can be inherited across generations. Fitz-James etΒ al. investigate the mechanism by which such epigenetic information becomes heritable in fruit flies. They show that physical contact between regions of DNA within the cell is able to trigger the histone modification H3K27me3 to become heritable.

Excited to share my new paper implicating the 3D genome in epigenetic inheritance. We show that chromatin contacts are able to trigger epimutation in Drosophila. I'm very thankful for the support of Giacomo Cavalli, @psarkies.bsky.social and to all others involved!

G3BP1 promotes intermolecular RNA-RNA interactions during RNA condensation Parker etΒ al. demonstrate that some proteins responsible for organizing ribonucleoprotein granules can chaperone intermolecular RNA-RNA interactions in addition to their role in scaffolding. These findings cement RNA-RNA interaction networks as a key component of granules, highlighting the need to further explore the regulation of RNA dynamics within granules.

@maikbischoff.bsky.social uses the fruit fly testis as a model of organ sculpting. The adult testis is a long spiral shaped tube encased in circumferential muscle, but at the start it is almost spherical without surrounding muscles. During pupation muscle precursors migrate onto the testis 2/n

Picture of a male (top) and female (bottom) zebrafish. Notice the male is more yellow and streamlined. The female is more white and appears larger as it carries oocytes/eggs.

Did you know #zebrafish can change sex as adults? Females that no longer produce oocytes can readily convert to a male, both phenotypically and behaviorally. #ZebrafishFunFacts πŸ§ͺ

I posted this some time ago on the abandoned platform, but maybe it’s worth advertising here as well:

I’m hiring a post-doc (18 months) for our newly established group at the Institute of Evolutionary Biology in Warsaw.

Apply by 15.12.2024.
