Sad to hear that David Baltimore passed away recently. He had an amazing intellect. First met him when I was a graduate student in Australia. Here is a photo of the two of us taken during a game of cricket in the Australian bush.

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/...
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. However, if wild-type twin clones are removed so that most eye tissue is mutant (left), the ed mutant cells survive and the eyes overgrow. See Research Article by Spitzer et al.

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)

The cell-adhesion molecule Echinoid promotes tissue survival and separately restricts tissue overgrowth. Read this #OA Research Article by Danielle Spitzer @dspitzer.bsky.social , William Sun, Anthony Rodríguez-Vargas, and Iswar Hariharan: journals.biologists.com/dev/article/...
Fig.3. echinoid clones are generated and then die, especially when more wild-type tissue is present. (A-F) Wing discs containing GFP-marked clones expressing either UAS-w-RNAi (A,C,E) or UAS-ed-RNAi (B,D,F). Heat shocks of 12 min (A,B), 15 min (C,D) and 30 min (E,F) generate clones at progressively higher density.  Scale bar in H applies to H-K. Scale bar in A applies to A-F.

This alarm clock cannot be adjusted for the time change! Good thing is that when she tries to wake me up tomorrow it will already be 6.30 am and not 5.30 am.

After walking one mile up a steep street this morning, this sign struck a chord.

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.
