Early embryonic development is a complex process where undifferentiated cells lose their pluripotency and start to gastrulate. During gastrulation, three germ layers form, giving rise to different cell lineages and organs. This process is regulated by transcription factors and epigenetic regulators, including non-canonical polycomb repressive complex 1s (ncPRC1s).

By making use of a Double-Headed-EP (DEP) transposon, a P element derivative made in our laboratory, we made an insertional mutagenesis screen in Drosophila melanogaster to identify genes that, when overexpressed, suppress the p53-activated apoptosis. The DEP element has Gal4-activatable, outward-directed UAS promoters at both ends, which can be deleted separately in vivo.

- Biofilms are dense communities of bacteria that grow on surfaces, and their growth is dictated by how they spread out horizontally versus growing vertically.
- The balance between horizontal and vertical growth affects the biofilm's expansion rate, which in turn influences its overall growth rate.
- Researchers found that the expansion rate of biofilms is influenced by the contact angle at the edge of the biofilm; this geometric factor, along with how quickly the bacteria double, plays a key role in determining how far and fast the biofilm spreads.
