Given how people look things up and the state of many of our tools to look things up with, I'm wondering if annually and manually updated printed reference handbooks will start to make a comeback.

Does my Speak-n-Spell feel pain when I type O-U-C-H? The jury is out. Philosophers and neuroscientists say that's fucking stupid, but I called a guy from the Center for Pretending that Household Electronics Are Sentient and he said there's no way to know for sure.

I cannot tell you what absolute fiction this is. AI is heading for a crash and this cackhanded Terminator narrative is being engineered to save them. The fact that the unsubstantiated testimony of a former employee has been the top story on BBC News all day is absurd and irresponsible.

Our BrainSaw serial-section 2-photon platform acquires whole-organ datasets automatically and requires minimal tissue processing. It has a growing international install base and has contributed to 35 publications. Learn more at: swcmicroscopy.com/brainsaw/ #microscopy #neuroscience
A BrainSaw serial section 2-photon system. This particular example was modified from an TissueCyte 1000 commercial system. Others have been built from scratch or were modified from in vivo multi-photon systems. Each BrainSaw is unique, but all run BakingTray serial section 2-photon acqusition software that plugs into ScanImage. Somatostatin tdTomato transgenic mouse imaged on BrainSaw serial section 2-photon. Full res images acquired at around 1 micron/pixel. Top images derived from 10 micron/voxel isotropic 3D stack. Detail from a BakingTray acquisition obtained from a BrainSaw serial section 2-photon microscope. Image shows three AAV injections leading to expression of fluorescent proteins (mCherry, GFP, and BFP) in layer 5 neurons of mouse primary visual cortex. Imaged at 780 nm.

Das alles fühlt sich zunehmend wie ein „Don‘t look up“-LARP an. 🫤
Das mitunter deprimierendste am Umgang mit der Klimakrise ist: Wenn man mit Umweltökonomen spricht, sagen die: "Das wäre alles locker machbar, wenn der politische Wille da wäre". Auch ohne große Einbußen für den Wohlstand. Einfach nur ordentlich besteuern & regulieren.
Aber je länger wir warten oder gar zurückrudern, desto drastischer werden in Zukunft die Maßnahmen sein müssen. Und irgendwann ist es halt zu spät. Das ist alles so unnötig, dass es weh tut.

The apical dendrite looks great, and does wonders in a slice. What does it do in the living cortex? It depends on the cell. A causal spatial role for apical dendrites in the cortex www.biorxiv.org/content/10.6... by @anyiliu.bsky.social with @kenneth-harris.bsky.social and @fedrossi.bsky.social
A cartoon providing a graphical summary of the paper. It is divided in 3 rows.

The top row shows a pyramidal cell and its apical tuft, and shows the two experiments that we ran: optical dendritic pruning (chopping off the apical tuft), and synaptic imaging done in the same neurons where we do somatic imaging. 

The middle row shows the results pertaining to neurons that prefer large stimuli (this is visual cortex): pruning reduced their responses, and the receptive fields of apical synapses are far away from the that of the soma. 

The bottom row shows the results pertaining to neurons that prefer small stimuli: pruning seemed to do nothing to the responses, and the receptive field of apical synapses are right around that of the soma.
