I’m currently looking for a post-doc in the UK, particularly to work on projects that employ in-vitro reconstitution and quantitative #microscopy approaches to study #cellbiology processes (esspecially #membranetraffic) + would be grateful for sign-posting towards openings! #academicchatter

Congratulations to the top 3 images from the Node–FocalPlane image competition!

1. "Cell-estial bloom" by Özge Özgüç

2. "Dancing actinotroch" by Allan Carrillo-Baltodano

3. "Who’s active?" by Julia Peloggia de Castro

"Cell-estial bloom" Image from Özge Özgüç:
A ‘Cell-estial bloom’ of human induced pluripotent stem cells (hiPSCs) flourishes on a micropatterned island. This image presents a colony of live hiPSCs, with fluorescently labelled Lamin B delineating the nuclear lamina within each cell. Acquired with a Zeiss LSM 880 Airyscan microscope, this maximum intensity projection is enhanced with depth-coded coloring to reveal the captivating three-dimensional landscape.

"Dancing actinotroch" by Allan Carrillo-Baltodano:
Actinotroch larva of a phoronid worm with phalloidin shown in yellow and acetylated tubulin in magenta. Imaged with a Zeiss LSM 800 at 10 x magnification.

"Who’s active?" by Julia Peloggia de Castro:
The image depicts a zebrafish embryo at 9 hours post-fertilisation on a lateral view. Cells are stained with MitoTracker, which labels active mitochondria, and cell membranes are labelled in cyan with a EGFP transgenic membrane tag. Image was taken using a 20x objective on a spinning disk confocal microscope.

(04 Apr) We have the first video of a plant cell wall being built

Plant cells without a cell wall are fragile, so it’s hard to image its construction.

Welcome to the new edition of #nakeddiefriday everyone. The guest today is the famous ESP8266EX by Espressif, a SoC loved by many in the electronics world.

Unfortunately, the digital section is fully covered by two topmost metal layers carrying power. We do have a glorious analog/RF section though.

ESP8266 overview shot, a mixed-signal SoC. About one half of the die is taken by the analog section.

Alright, let's get the #nakeddiefriday going.

Today's exhibit is AR9281 by Atheros, a very classic Wi-Fi chip found in many devices. Comes in very pink hues. A short thread with highlights follows.

A thought I've had a few times lately: my current setup is far from sufficient for this, but in the future I think it might be fun to try livestreaming a bit of microscopy. Would anyone actually wanna watch such a thing?

I'm not saying it would happen anytime soon (or ever), but I may start looking into what upgrades it would take to make a livestream feasible if there's any interest. Poll below if you think that sounds neat ig

and as a thank you for reading this whole thing, check the replies for a low-quality cystidia pic

83%Yes, I'd watch a mushroom microscopy stream
17%No, not interested

Hello and welcome to this week's installment of #nakeddiefriday !

The guest of today is the TIBPAL16R4 by TI, a programmable array logic chip made with bipolar logic. The die has 2 metal layers, its maskwork produced in 1985. A short thread follows.

How do other microscopists / photmicrographers cope with the prospect of wading through almost a years backlog of collected images and video, approx 250GB of HDD space or a quarter of the whole HDD - to decide what to keep and what to delete. Any Advice?
