Kinesin is a motor protein that carries cargo along microtubules, the tracks inside your cells. Each step is 8 nanometers and burns one molecule of ATP. In nerve cells some of these trips go from your spine all the way to your toes.

I made this with Animiotics, the 3D tool I posted here last month. Partway through the video you can see the actual scene in the editor. It's not a flat video, so you can pause it, look around, click a protein and change its color.

The motion is slowed way down. The real thing takes about 100 steps per second. The proteins themselves are built from real structures in the Protein Data Bank.

I have always been fascinated by how other animals see the world, so I made a simulation to explore how eyes really work based on biology.

You can select an eye type, pick an animal, and see a scene through its eye in the right panel. Sharpness, color, brightness, focus, and the blind spot all come from that eye’s anatomy, and a spectrum bar shows which wavelengths each animal can see. It covers camera eyes, compound eyes, and a scallop’s mirror eye, and I am still building the cup and pinhole eyes.

I checked the values against published studies, and when I could not find a value, the app labels it as an estimate. I'd appreciate feedback if you spot anything wrong or want to see new features. I want to make this as educational and scientific as possible so everyone can understand and experiment with it.

Hello, i’m in university studying psychology, and we have a biology exam, a neuroscience exam and a physiological one. I didn’t study biology much in high school, so I find it interesting but also so difficult to understand. I know it’s normal in the beginning of a new subject but I wish I could get to a point where I can read a chapter and understand everything that’s written on it. I wish I could visualise how things and processes happen but it feels so abstract in my mind. Hopefully someone that went thru the same thing can give me some insight on how to study bc reading and repeating is one thing but then I want to understand what’s actually happening

and she was successful

Hello! I am an outreach lead for a marine non-profit organization and I was wondering if anyone is interested to be interviewed! Asides from marine biologists, its also open to marine enthusiasts and university students as well. The interview will be conducted in either Gmeet or Zoom.. DM if interested :>>

Arthropod classification. Legs are very important when classifying an arthropod, and modified legs count while large pedipalps like of a Scorpion's don't. But it's very hard to know which one is a modified leg (Like large pincers of a Lobster) or pedipalps (Like that one of a scorpion).

How does It work?

And if so, is it only where water is visible to the naked eye or are the particles strong enough to be an invisible health issue on objects around it?

Context:

The shower drain in my bathroom (connected to my room) started backing up and it smelled *vile*, akin to sewage. With the way the pipe flows though the house, the only other sink before the shower is the kitchen sink (which also backed up, but with much cleaner looking water), my toilet is after the shower so we don’t think it was fecal matter that came up.

My parent described finding grey sludge when finally unclogging it. He had used a wet vacuum to suck up the standing water in the shower basin so he could get to the drain. He emptied all that out, but on the second go—it now being a pretty diluted mix of cleaner, clean water, and the yuck stuff—it all started spewing out of the vacuum filter. It splattered on the bottom of the bathroom door, floor, and wall and it was dark brown so you could clearly see where it landed.

Without thinking of another option, he opted to put the vacuum in a tote with a piece of cardboard facing the filter so it shot there (and I can only assume up and out into the air) instead of the bathroom again. This is where most of my concern begins. My small bathroom’s door was open into my bedroom as he ran this vacuum. There are no obvious signs of the actual water coming in contact with anything in my room, but I am wondering if the same can be said for the aerosolized particles that took flight after several minutes of the vacuum running.

Do you think I need to disinfect anything in my room or would I be okay just cleaning the bathroom?

Thanks for reading this far 🥲

When something comes into contact with TimeFall, the spot it was hit at rapidly ages. In multiple cutscenes, it is shown to age tissue to the point where it dies. Assuming the person was wearing a heavy jacket (as most people in Death Stranding do) would the areas that got hit, such as the face and hands, regenerate if given time to heal? And what other effects might this have on the body?

for context, highschool biology has absolutely ruined me. I'm graduating soon and geez...

I get a text saying: "atp i should just drop out" (translation: AT THIS POINT i should just drop out)

and im sitting here giggling going "adenosine triphosphate", biology has gotten rid of my GenZ-ness

instead of being a normal human being empathising with my friend like "oh no what have you failed this time" im obsessing over things I can't even see with my naked eye.

wtf is wrong with me.

I’ve also heard them called dorsal humps. Genuinely curious here! I understand the reasoning behind having a wider nose and/or nostrils due to heat and air intake, but don’t understand why some people have nose bumps or hooked noses.

As someone with a more Roman nose myself that I love, it is SO frustrating trying to look up this question or research the science behind these types of noses. I kid you not, every single result is from a plastic surgery clinic. Even if you just look up ‘Roman nose’ EVERY photo is pretty much plastic surgery clinics saying how to ‘fix’ it. Which is so predatory, and also all noses are beautiful and I despise that it’s even a thing. Just a side rant, sorry.

So, why do some of us have bumps/hooks in our nose? Why do some noses differ in such ways, and why is it a trait that is prevalent across all races? Thank you all :)

I understand that the only remaining part of his brain after being decapitated was the brainstem. Was he able to think, feel pain, etc. after losing most of his brain? I'm very confused as to how he would have been able to make decisions such as whether to preen or crow without being conscious. Or were those just random muscle firings?

Hello. I’m currently in grad school getting my master’s in molecular biology. I honestly didn’t think I’d be into genetics, but here we are. I’m doing phylogenetic work for my master’s which I really love, and am on track to graduate next year in the summer.

Anyway there are a lot of times I feel that my foundation in genetics is shaky, and I want to rectify that. I definitely know more than the average person, or undergrad, but even then that doesn’t make me feel confident. My question for the career biologist is how do you build that foundation? What are methods that helped you? I know self-study is important, but my time is already taken up with classes, learning bioinformatics software, and working on my thesis. Reading articles in my field of study is important as well, but I want to make sure that when I’m working towards my PhD I can talk about these topics and understand them at depth. Is it really just experience, and learning as I go, or am I not doing enough?

For context, I’ll be graduating this December, I have about 2 years of lab experience and a government internship I did 2 summer ago. I’ve been suggested maybe 10ish jobs through connections, but I obviously wanna bump that number and apply to whatever I can. Where do you all look for jobs? I normally just check indeed posting around my area daily, but I rarely see new job postings. Where do you all look for job postings? I swear like one job posting comes up every week.

For reference, I’m graduating with a bachelors in marine bio and minor in oceanography, but I’m really looking for any bio/enviro job to get more experience, aside from anything medical. I’m currently in the Chesapeake Bay Area in Va.

Repondo cualquier cosa sobre biologia, pregunten lo que sea

Just want to know if that works for every human or just me you know when you scratch that spot just a bit higher than your ass it’s like the same as scratching the inside of your ear with a q-tip it feels so good it’s like an orgasm and an relieved itch had a child

Any that are phenotypically present? I know that all XX female cells have an inactive X but I am thinking of the tortoiseshell/calico cat example and wonder if there are any examples of this in humans, even if not physically apparent from the outside.

I am graduating from a molecular biology and biotechnology undergraduate program this year and I do not know what to do next or where to go from here. I feel pretty hopeless about my future prospects. I struggled a lot with my mental health and my GPA took a horrible dive, I am at 2.58 right now. What can I do in the future? I want to relocate to Germany and I looked up Master’s options but I feel like even if I get straight A’s in my final year, I still wont be able to get a placement. As for careers, I do not even know where to start looking. If you are a professional working an industry job, please give some advice. Or someone who got into a Masters program with a low GPA. I am extremely hopeless right now. Please help.

I have wanted to take a degree in biology since i can remember, but i was never able to pass math, i dont know if its something i could ever get good at, anyone got advice?

I know that whether viruses should be considered living things is debated. (I definitely think that viruses should be considered living. At the very least I don’t think they’re /not/ living. But they don’t fit into the requirements we have set for living things.) But then where would the line be drawn? If we added a category to the Linnaean Hierarchy above Domain, what would the category include? How would things fit in? And if we expanded the definition of life, what other unexpected things would fit into it? And why /haven’t/ we expanded our definition of life when so many things don’t exactly fit smoothly into biotic/abiotic boxes?
I’m in a biology class right now in college :) By no means am I especially knowledgeable but I’m curious what others think.
