"The most uncomfortable part for me is that I no longer think that scientific research will resolve the crises that we face."
"I keep doing research not because I think it will save us, but because it would be a form of surrender to stop seeking understanding."
"I keep doing research not because I think it will save us, but because it would be a form of surrender to stop seeking understanding."
Why do I continue to conduct research when it seems to me that it is likely to decline in the coming decades and therefore will not enable us to resolve the major crisis of the Anthropocene?

To me the chatbots pose zero interesting questions about the ‘nature of selfhood’ but dozens about the nature of manipulation. Here the Claude team pretends they are programming the robot for ethical responses but they land on one that is false and disingenuous.

San Franciscans were poised to walk out of workplaces & schools on Friday, flocking to Dolores Park to join the national "ICE Out" strikes.
A few hours before things start, the only visible signs were "ABOLISH ICE" stickers plastered over street signs.

Our lab will be boycotting biotech vendors that have contracts with ICE (e.g., Fisher, Agilent), and telling them why. If you google “vendorname usa spending”, you can see purchases for specific depts including ICE on usaspending.gov. Please talk to your labs and email your vendors!

This is all stupid bullshit but I remain pretty disgusted at how things like marriage and having children are treated like Xbox achievements instead of actually loving and caring for someone else. Yeah I’m going to work 70 hours a week but definitely need a spouse, her name is Beth or something idk

My sister-in-law's dad died last week, in hospice in the VA hospital in Minneapolis. I just learned Alex Pretti was part of his care team. They shot Alex less than 1/2 mile from my niece's house while doing the same observation work that my niece is doing. These are real people. Step up folks!

Chlamydomonas in lab have a new year's resolution to practice their interpretive dances even if a flagellum/cilium falls off. I hope you enjoy as much as I do even if this is potato quality compared to fluorescence. (50 seconds long video)
