Out of all the mammals other than humans, I find myself most fascinated by the porcupine. Out of all the mammals, it's probably the one where if I didn't know about porcupines and someone described it to me I would think it was a made-up animal like a unicorn or a jackalope.

>>8706681
I was curious so I looked it up and turns out the animal can actually regrow the hoof from that state, with a bit of help.

>>8707239
yes but it also works for behaviours and logical schemes, kinda registers a "plan of action" be it a motor act or everything about planning.
for movement is probably the reason we can do such complex reactions on istinctive level, differently from most wild animals that only have a very limited number of istinctive reactions (run, jump, bite, etc)
i find very appealing that it works on behaviours too, and on logical thinking, making problem solving something istinctive

What the other anon sais. It's a pretty cool phenomenon. You can basically see it as a very rudimentary nervous system. What he described was chemotaxis, there are other ways of ortienting yourself, for example, to light and that's called phototaxis then.

I wish I had the photos on me but I'm not at my laptop right now. The attached image isn't the actual patients blood smear but a very similar picture was seen. I know the photo is bad, I had to steal it from my textbook but I literally could not find another photo like this online.

We had a woman come into our hospital with her 3 and a half year old child claiming that the it had the flu and was constantly sleeping. Child was crying incessantly, had fainting spells, etc. Cerebral spinal fluid was drawn to rule out possible bacterial infection (meningitis).

A microscope smear was made and this is was what was seen.

The first tech that saw this thought that it was a bad stick by the doctor and that they had wiggled the needle or tried multiple times and thus the sample was bloody from that.

But that's not what the answer is.

Can you guess what you're looking at with the child's symptoms in mind?

The red blood cells present in CSF is already an indicator that bleeding is occuring. We can guess we're probably at 400x or 1000x magnification and we're already seeing what looks like three neutrophils at the top and far left of the image (they're distorted due to this being a cytospin smear). But all that foamy looking stuff in the center doesn't quite look cellular. It's actually brain tissue. That entire center of the field is a large chunk of brain matter that has broken off and was collected when aspirating CSF.

The child had shaken baby syndrome something awful. Severe brain damage had already occurred and hence why we were able to visualize brain tissue. The only time I've ever seen this happen before has been with severe head trauma patients but even then its very rare.

>>8709436

Did it die?
And why do you avoid saying the kid's gender?

I'm unsure what happened. I suspect he likely died. I do know that social services were called and he was separated from his mother.

It wasn't pertinent I guess. I get used to speaking like that since I don't want to divulge too much patient information. It was however a boy.

I think the idea is more that the wasps learned to recognize the smell of the plant being in distress and go take advantage of the easy meal. Not that weird or implausible.

Guys i have a question about GMOs
now here me out i'm not some kind of green peace "GMOs KILL!" type of faggot. If all of our food products are GMOs, there are a chance that a super virus can knock out all the crops like the banana extinction back in the 60s. So my question is: Is there a way to make GM products but make it so they have biological diversity among themselves i.e. a crop of corn being biologically diverse and not all of the plants die to the virus.

Those are legit questions if it isn’t some kind of Christfag YEC meta-bait. But let’s assume you’re sincere.

There are a lot of books on evolution that answer those questions a lot better than I ever could. But here’s my two cents anyway.

First off, if a creature evolves to have a particular trait (camouflage, talons, a big bright tail) it can only evolve to have that trait within the confines of its own embryology. The trait has to “fit” in the developmental procedures the species goes through each generation.

Second, everything costs something. Economy -as in the allocation of limited resources- is a big deal. A big bright tail may win you all the females (and get you laid!) but you pay for it. Maybe by having a smaller body overall or by being less agile in flight.

Third, natural selection can only “work” on the random mutations that occur. It might be cheaper and better to evolve a poison or a bad taste to defend against predators, but if no mutations occurs that can lead to the development of a poison than it will never happen. So chance plays a big roll too.

There’s lots more and a lot of it is more complicated and ingenious than you might think. So pick up one of those books.

Arthropods feel pain far more vividly and intensely than any other organisms, but people pretend that they don't in order to not feel bad about smashing them or boiling them alive.

Fuck these captcha's about store fronts

>>8710556
Wait which bird are you talking about? Because the small one doing the chasing clearly has talons.

The big ones don't have them because they wouldn't have a use for them 99% of the time unless they were fighting, which is a base they can cover with their beaks, which they actually use often in order to get the food they eat.

A lot of them can spend brief stints on land, and a few can go for hours. They feed on stuff that thrives in tidal pools, so they are one of those species aiming at a water->land transition.

tfw future generations might have to deal with future octopi rummaging through their trash... Less dangerous that bears, I suppose, but a lot more icky.

Not likely to get very far into space without some genetic modifications, so show some love to those greasy grimy biology guys.

Cybernetic enhancements you mean

>>8714091
Well, that works too, I suppose, or some combination thereof, but cybernetics involves some serious biology.

how does he not get stunged?

>>8714422
Armor, and not wandering into the nest. Other bee tried to sting him, and became the second course of his meal.

More impressive when wasps do it - fuggers actually dig inside with hundreds of bees stinging them and just dieing. Apparently immune to the venom, in addition to the armor.

Although, some bees have developed an interesting defense against such hornets, cook them:

Evolution is just a process of the things that don't die before they reproduce passing on their genes. Sometimes that stuff that doesn't die isn't necessarily the best, it's just good enough.

Wow, a guy fucking a girl I'll never fuck just like every other porno, except this time his original dick was 70% the size of the fake one instead of 50%, and he has dark skin. Truly, this upsets me more than anything else in the world. If only some people didn't have slightly larger dicks than me and darker skin, my life would be better.
