Don't we all?

That pic is valid because it's a lab in Australia. Sheesh! Use some common sense.

If you hold the picture upside down the dna spirals the right way.

Even if we assume that he's wearing a ladies shirt for a moment... Why does he have that stethoscope? Is this what doctors do when the patient is waiting in the exam room?

You can tell what type a base pair is by listening to the tone it makes, but it's very quiet so you need a stethoscope.

I once saw a shutterstock photo of someone using a large soldering iron on a motherboard, holding it like a pen (so holding the hot part). Stuff like this is so poorly done and fake, it's at the level of porn acting.

Here is the sacred tome you refer too m'lord wiggle;
Seriously though, is this the one you were thinking of?
I'm fairly sure this is the original I saw; But searching for "woman, soldering iron" results in many copycats, so it's hard to say if this is actually the one from back when, or if my mind just misremembers it as such.
- Saw her at the range the other day
- Not OP, but I've seen this one years ago. Defo the one.

Most useful stethoscope ever

That's clearly a selfie made with iPhone, which is why it's mirrored...

You see both his hands. So someone else would have to use the selfie camera but also make sure they are not in frame. I mean, it's not impossible, but it's highly unlikely. As much as I would like to blame Apple products, it's more likely this is not a mirrored image but human stupidity. Seeing what's happening in the world these days, I always assume everything is human stupidity unless there's proof it's a technical error or something. Although everything Apple related is also human stupidity.

It's obviously some smoothed Z-DNA

"That's it, Dr Scientist, you're not taking this seriously. YOU'RE FIRED!"

"Good! I'm a maverick, I don't play by your rules! Fuck you, here's my badge and my gun!"

"Wait, why do you have a badge and a gun!? We didn't issue you those... You work in a lab!"

Wow, okay racist

Flip it horizontally?

You could flip the image but the thing about a spiral is that it’s the same no matter you turn it around in space.
- If you physically spin it, yes, it wouldn’t change its direction, but I was talking about flipping the image horizontally.
