Those “spines” are called papillae, for anyone wanting specifics.

Crankenstein@lemmy.worldto Science Memes@mander.xyz•Hertz, showing the difference between science and engineeringEnglish6·15 days agoThose practical methods would never have existed if not for Hertz’ experiments. Those were 25 years of other scientists, having seen that this new concept exists, refining his contraption into what eventually would become the machine that we know as a radio.
Crankenstein@lemmy.worldto Science Memes@mander.xyz•Hertz, showing the difference between science and engineeringEnglish29·15 days agoI absolutely detest the equivocation of “benefits society” and “marked for profit”.
Plenty of things have been discovered to have practical applications which can benefit society yet are shelved or have its implementation frustrated because it cannot be exploited for profit or threatens the profits of a preexisting application which it would replace.
I expected a lot of travel for the career, I just was naive in expecting that travel to be reimbursed as it’s a condition of the job. Nope, gotta foot the bill yourself.
I have passion for this career in conservation but, unfortunately, I also have to be able to afford the cost of living.
Crankenstein@lemmy.worldto Science Memes@mander.xyz•Eating shit is for alphas, am I rite guiseEnglish42·20 days agoHaving met a few nut jobs who are all about pseudoscience like homeopathy, crystal healing, and other forms of ‘natural alternative medicines’, this is exactly the type of shit I would expect them to say with a straight face.
Satire needs to be exaggerated to the point it is clear no one would actually say something so outlandish. This misses that mark.

Me with a degree in wildlife conservation!
Yet finding work is almost fucking impossible and dealing with the bureaucracy of job hunting is so overwhelming, my unmedicated AuDHD ass cannot keep up.
Unfortunately I have no hope of this happening in our lifetime. Maybe the lifetime of the next generation, but with climate change on the horizon, I have little hope for that as well.
Crankenstein@lemmy.worldto Science Memes@mander.xyz•Curious minds want to know!!English16·20 days agoThis was fun researching and theorizing. Thanks for asking.
We experience brain freezes when a sharp temperature drop comes into contact with the roof of the mouth and back of the throat, causing the blood vessels to constrict, which in turn causes the arteries in the brain to expand. It isn’t exactly clear where the “pain” comes from though; it is theorized that the arterial wall’s expansion triggers the trigeminal nerve (relays sensory info between face and brain) and is registered as a pain sensation.
Shark anatomy is entirely different in structure, such as they don’t have the same complex nervous system. Also, considering they are ectotherms, their body responds in completely different ways to changes in temperature than we do.
So considering what we know about shark physiology and the current theory on the mechanics behind “brain freezes”, probably not.

Crankenstein@lemmy.worldto Science Memes@mander.xyz•Curious minds want to know!!English20·21 days agoYou know how human teeth have those prong bits that anchor into the gums, the “root”? Inside those are the nerve canals: spaces filled with a pulp that nerve endings run through.
Shark teeth don’t have these canals in their root. Their teeth aren’t anchored into the gums and don’t connect to any nerve endings.
Still consuming it; so just “feeding” it in a different sense.
Needs some yellow.
This is one of those “if you cut a hole in a net, it then has less holes than before” type arguments and I’m all here for it.
More a biology lesson. It’s the scientific word for the appendage. Human’s — I believe all mammals as well — have them lining our lower intestines. They help us absorb nutrients by increasing surface area.
The word itself, papillae, just means “a small, rounded part which protrudes from an organ/ nipple” from Latin.
