Issue 15 is complete! On the cover: When echinoid (ed) mutant clones (white) and wild-type twin clones (red) are generated in the developing Drosophila eye (right), the mutant tissue is eliminated. See Research Article by Spitzer et al. journals.biologists.com/dev/article/...

My PhD work from @hariharanlab.bsky.social is finally out in @dev-journal.bsky.social! We investigated an interesting paradox: how can reduced function of the adhesion molecule Echinoid (Ed) cause seemingly opposite phenotypes—overgrowth and elimination—in different contexts? (1/8)

Today is the 136th birth anniversary of the amazing mathematician Srinivasa Ramanujan - celebrated as National Mathematics Day in India. Maybe every country should have their own National Mathematics Day.
