Last night Adam Kampff, the glue, the light, the catalyst, the builder, the smile, left us. He and his work transformed the lives of many labs, scientists, students. He inspired and was generous to his last transformation, working tirelessly to set up a foundation to continue the work.Thank you!

I doubt a new party is going to get 20% of the vote in any reasonable time frame. Certainly not by the next election, which it what we need to stop Farage.

1/ Mapping synaptic connectivity between individual neurons is extremely laborious. We developed BRISC, a new method that makes it possible to map inputs onto 100s of neurons in the same animal in a matter of weeks! Led by Alex Becalick and @antblot.bsky.social. 🧵

This won't kill it, it will just hurt people with lower incomes. It needs to be carefully dismantled by enlightened governments. We are a bit short on those however.

Many of us use 2p scopes to image 3D volumes of brain. But then we analyze the data plane by plane, resulting in duplicated neurons, missed neurons, and low s/n. Let's go 3D!

When I first joined here I remember there being a lot of posts about how the 'culture' of bluesky was to block liberally and starve the trolls.

I just hope people are still doing that!

Everyone who is able should be doing this. And growing as much of their own food as they can, and saving seed

But individuals can only do so much, and millions don't have the means to stockpile or grow

The government should be making appropriate plans NOW

I returned two objectives to Nikon with damaged front elements. It took several months to get them back and cost was about 50% of new. A different time I returned an objective that seemingly spontaneously started to produce a horrible PSF. Took many months but was never charged.
