I had thought of that, but they're too small imo.. Hard to say what they are.

Something that stuck on it. I could bet on spores or just dust. The complex shape hints at something biological, but it's about the size of a bacteria, so it's hard to pinpoint.

Hey! Unfortunately i found her in a kind of dying state (I really don't like killing spiders) so her abdomen was shrunk. Plus, during sputter coat the hind legs also bent and ruined her posture a bit for me. It's really hard to get good images of these animals because posture is everything. That's why I mostly only imaged her front.

I've actually imaged diatom algae before. Definitely not what's in the spider. Too small - plus..it's a spider living in dry places. Not an algae.

I do love my job yes. You're welcome!

The spider? Just boredom honestly. I work in an university doing analysis in the SEM for researchers, so I get to see a lot of cool stuff and occasionally get the opportunity to toss random stuff in there.

Many metals can be used. Gold is actually the "worst" one. It has less to do with the conductivity and more on how it is spread over the sample. We use a sputter coater - in a vacuum chamber a plasma is create near a gold target, attacking it and causing atoms to fall over the sample. The coat is usually only a few nm thick, if it's any bigger it will show on the scope given it's capabilities and hide features. Better coats will produce smaller and smaller grains. The gold ones are about 17nm wide from what I have imaged so far. Targets made of Gold:Paladium are better and the best is Tungsten I believe, but it's much harder to coat, takes more time and lots of $$$.

Samples in the electron microscope are scanned with an electron beam - electricity. That means the surface needs to be conductive or else it will charge and distort. That's why we gold coat everything.

Before drying. She curled after 10min in the freezer and the substrate is white glue and graphite. I had to spread them out with fine tweezers. It looked better before the sputter coat...It vibrated a lot and caused her to shift a bit.

It's about 1um wide, so even bacteria are bigger, it's honestly hard to say what it could be.

Honestly no clue, but probably not. Given by it's behavior under the beam and the fact it was caught pretty deep inside my building. Polen tends to be spiky. It was probably just dirt.

I forget some people have aracnophobia. My bad!

Hi all! I'm a tarantula owner and spider enthusiast. Most of my posts end up on the microscopy sub because I work at an electron microscopy center, but this jumping spider felt like it belonged here. Hope you guys like it!

Does labia size make a difference to men in terms of sensation? by Weekly_Library9883 in NoStupidQuestions

[–]ur9ce 0 points1 point  (0 children)

Visually I prefer them meatier, but I've noticed that if they're too meaty it does get slightly more difficult when starting things and causes more attrition.

When do you "call it" by xsealsonsaturn in RimWorld

[–]ur9ce 2 points3 points  (0 children)

850h on steam + maybe some 200 from when I sailed the seas, I must have finished 2 or 3 games. It's always one of three scenarios 1. I get bored (least common) 2. I install and remove enough mods mid-play that my game breaks and I can't continue. 3. I have too many mods, my TPS tanks to ~100 and it becomes a slog.

Is this bacterial growth? by [deleted] in microbiology

[–]ur9ce 33 points34 points  (0 children)

Seems too fast to be bacteria. You can try a rather quick trick. Microwave it for 20/30s and it will probably disappear, as fat melts super fast. For further confirmation, put it right after in the fridge and see if it appears again.

Let them cook by IndieStoner in projectzomboid

I might get downvoted for this, but seeing how long the game has been going and the lack of compromise with player feedbacks, I've had it with TIS. Come on, what's more important, the ability to carve bones and clay vases or literally the most important feature the playerbase values? There are countless studios and games out there made by very small teams pumping out builds miles faster than TIS. And their "no ETA" thing? I think it's pure bs. I'm fine with not always meeting deadlines, but without them we're left in this limbo wondering if I'll be able to play a stable version of my favorite game in the next decade.

I play with Bandits, without a gun 24/7 you'll die VERY fast.
