A mutant screening report identifies several female #Drosophila recessive sterile alleles that resulted from the insertion of the mdg4 retrotransposon into the OVO transcription factor gene locus. 🪰 Learn more about these sterile lines in #G3journal 🔗 buff.ly/Vn9cdYt

Sharing an image capture of Polytene Chromosomes from salivary glands of third instar Drosophila melanogaster larvae. Coolest Part? They are so massive that they are readily visible under a basic light microscope. #SciSky #Biology #Drosophila #Research #Microscopy #PolyteneChromosomes

SPARC mediates tumour–stroma intercellular communication through endosomal regulation of Delta and Notch signalling

Tumour progression relies on reciprocal communication between genetically altered cancer cells and surrounding stromal cells. While the genetic alterations that initiate tumorigenesis have been extens...

(1/4) How is the timing of cell death regulated? We have developed a #liveimaging system to follow the dynamic cell death of #Drosophila hepatocyte-like cells (oenocytes) in intact pupae throughout metamorphosis. Watch some beautiful videos from our #preprint in this thread! #DevBio #CellDeath

Hepatocyte-like cells die via steroid hormone and nuclear receptor E75-mediated apoptosis

Metabolic organs must sustain physiological function while retaining the capacity for timely cell death. Systemic hormones play a key role in coordinating this balance, yet how they regulate cell deat...

My first paper is up on bioRxiv! We asked a simple question: why are fruit flies smaller when they grow up in a crowded vial? #Development #Plasticity #Drosophila
Micrographs of two Drosophila melanogaster pupal cases. The left pupal case is slightly larger than the right. The left pupal case is marked uncrowded, and the right is marked crowded. A 1mm line is above the pupal cases for scale. Both are males reared on low nutrition; the left is from a vial with 50 larvae, the right is from a vial with 200 larvae.

Room to breathe: Nutrition and developmental oxygen modulate the crowding effect on size in Drosophila melanogaster https://www.biorxiv.org/content/10.64898/2026.07.02.736161v1

Two contributions from our lab at #ICS2026 - Kristína and her poster on #Drosophila glycans and Alba and her talk on #Dictyostelium glycans - in both cases some weird & wonderful structures - solved without databases, with much of the brain work done by Katharina Paschinger.

Final thought: development is not one fixed script. Evolution finds different mechanical solutions to the same morphogenetic problem. Or, more simply: when things get crowded, the beetle finds another dimension. 🪲 #EvoDevo #gastrulation #morphogenesis #development #Drosophila #Tribolium
