Moths and light bulbs: nature’s greatest love story? Not quite. 💔💡
Turns out, for moths lamp is not life and artificial light is quite disruptive to their routine.

Hi there

We are having Biology Innovation Project(for Robotics) and me and my team were looking through some issues in Biology and we came across freshwater acidification. We want to figure out ways to neutralize this without affecting marine life, without releasing Co2, and should not cause some chain of chemical reaction. We looked at Magnesium Hydroxide but we noticed that all hydroxides cause a sudden jump in PH. Do you guys have any ideas?

Thank you in advance!

There has been a lot of talk recently on bioweapons.
And it got me thinking, how likely is it that a country right now is developing a supervirus/superbacteria with the explicit reason inflict as much death as possible?

If there is one being developed, how deadly can a genetically engineered weapon theoretically get?

Im referring to this cambridge interview question https://www.youtube.com/watch?v=I44rE02W0m0&t=585s

My question is

1. What do they mean when you are upright your ribs are sloped at an angle?

How does that cause the front to back diameter to increase?

Im a little confused on the dogs part, ribs are horizontal to your spine, so movement of ribs isn't going to help your chest diameter, so whats the point of the ribs? part. Why woudl movement of ribs not help chest diamter? Im really lost from 7:30 - 9:30 part.

Anyone got a simpler explaination, or can point me to some i.e youtube models that show it in action?

https://ibb.co/Rkm4Yvjw - is this drawing semi accurate, aside from the angles bit?

Hey!

I recently came across the fact that spotted hyenas have really difficult births because of their anatomy, and now I'm curious to learn more about it.

Does anyone know any good resources on this, or would anyone who's familiar with the topic be up for discussing it? I'm also curious if there are other wild animals that have similarly difficult births.

Thanks!

Cause it said KIDney, so like a kid comes from there.

It also didn't help that the kidneys sort of looked/shaped like a foetus.

I thought in women it got like fertilised and then it got bigger and when its time for birth it'll just fall off like an apple from a tree and move downstairs.

And it was dormant in men, cause they can't get pregnant.

I also thought that twins are born when both kidneys are fertilised.

This was when I was younger btw.

The human brain operates through electrochemical processes. Plants also use chemical and electrical signals to sense their environment, process information, and respond.

We call one system capable of consciousness and generally assume the other isn't.

But if both operate through physical and chemical processes, what exactly separates complex chemistry from conscious experience?

I'm not claiming plants are conscious. I'm questioning whether we actually understand where consciousness begins — or whether we're defining it by what resembles ourselves.

Not sure if its a worm or a caterpillar couldn't see if it has a tiny clwas .. it kinda moves fast which shock me I didn't realize it was on my foot setting in a public place.. and found other ones which wasn't there when I arrived.

A POLAR BEAR

New question also related to the project from yesterday’s question. Like did the ancestor to the Portuguese man o’war already have the specialized zooids for the sails, the tentacles, and the mouth? (As well as others) or did they have to evolve to have the different zooids being different?

Bonus question, do each zooid have a “stem cell” stage where it’s undifferentiated? And if so, how does it know which one to become?

I live in Maryland, Baltimore county area and graduated with a Bachelor's (concentrated in molecular and eco/evo) back in May. I've been applying since. I've been trying to get into some basic lab work as a research assistant, QC/QA or lab tech but I often never get a response or I don't get the job. It doesn't help that I have no drivers license so I'm pretty limited to what's reasonably commutable.

I really wanted to build up some proper lab experience before I go back to school for a Master's or PhD since I want to do research.

I dont have any professional lab experience and never got to do summer research programs. The most I did was environmental work, like garden maintenance, invasive plant removal, trail clearing and deer cage clean up, which was followed by an internship with the environmental department of my school. As much as I would like to do more Eco/Environmental stuff in the future, my focus is getting my foot through the laboratory door.

But I have no idea how to actually standout as an applicant. When I'm competing with other applicants that actually have experience or have higher degrees than me.

I just passed out from an IV. something that will directly help me, why? Is my body stupid or something?

I've been thinking about evolution, and I realized I don't have an answer to how life went from bacteria and such to multicellular bodies. It doesn't make any sense that a single cellular organism would evolve more cells, so I was wondering if there's a straight answer to this. I googled it, but I didn't get a clear answer, so I'm asking Reddit about it.

Hello! I am a freshman in college and I’m a biology major! In my lab classes I am struggling with my goggles fogging up every 5 minutes. I sweat a lot due to a medicine I am on, so I suspect that is why they keep fogging up. I’m looking to buy a good pair of goggles that are glasses friendly and anti fog to help this issue, any suggestions? Thank you for your help!

middle aged adult drop out back in academia after years being out. I am doing my Biology 12 and my Midterm is next Friday. PLLEASE HELP, I really could use some resources to memorize definitions and just all around be more ready for my test.

I was chatting with my friend who is themselves an med student and we were talking about biology I have kind of an free amateur armchair level of knowledge I was really fascinated by genetics in high school and early uni before I went off to Art School. Anyway we got into a conversation about sex like biological sex and I had always been told that sex is made up of your chromosomes but I had also heard from that it was a lot more complicated and there was several other properties so I thought I'd ask. My friends said it's true that sex is comprised of multiple other things but before we could continue talking they had to leave so I wanted to ask for a more of a explanation of it that's okay

So, let’s say there’s a species of starfish, OK? Now we consider adult starfish to be radially symmetrical, right? But let’s say this species starts to evolve a peak at the center. This peak slowly but surely evolves to be pretty long, and now they move around like a worm. They’re still radially symmetrical in their plane of origin, but if you orient them to how they usually are, they obviously aren’t anymore. Would that still be considered radially symmetrical?

Hey everyone!

I’m hoping to find someone with a background in biology, ecology, evolutionary science, or a related field who enjoys speculative evolution and might be interested in helping me with a personal creative project.

For some context, I’m building a science-fiction universe called Project: Damocles, which I’m currently working on turning into a comic series.
Something I’ve always wanted to achieve with this universe is a certain level of scientific credibility. I don’t expect everything to be possible according to our current understanding of science, especially considering the setting takes place far in the future and involves extraterrestrial life. However, I do want the things I create to follow understandable principles instead of relying entirely on artistic freedom.

That brings me to the reason I’m posting here.
I’ve been developing various alien species, creatures, and environments, and while researching their biology myself has been incredibly interesting, I’ve also realized just how much there is that I simply don’t know.

I’d love to exchange ideas with someone who understands how living organisms function and evolve, particularly when it comes to things like anatomy, biomechanics, environmental adaptations, food chains, and the relationships between organisms.

I’m especially interested in exploring how life might develop under conditions different from those on Earth. Different gravity, atmospheric composition, climate, and evolutionary pressures could potentially produce some fascinating organisms. Finding out which ideas are plausible, which need adjustments, and which would be outright impossible is exactly the kind of feedback I’m hoping for.

I already have several designs and concepts that could serve as starting points, so this wouldn’t involve creating an entire biological world from scratch.

What I’m looking for isn’t someone to do the work for me. I’d mainly appreciate having someone to discuss ideas with, challenge my assumptions, point out mistakes, and occasionally help me find more scientifically reasonable solutions.

A little transparency regarding the project: this is an independent passion project without a budget for consultants, so unfortunately I can’t offer financial compensation. I’m aware that scientific expertise is valuable, and I completely understand if that makes the opportunity unappealing.

There also wouldn’t be any deadlines, assigned tasks, or obligation to participate regularly. I’m simply hoping to connect with someone who enjoys this kind of subject and wouldn’t mind the occasional discussion.

Naturally, I’d be happy to acknowledge any meaningful contributions in the comic’s credits and other relevant material as a scientific or biological advisor, if that’s something you’d like.

If this sounds interesting, you’re welcome to leave a comment or send me a message. I’d gladly share some existing creature designs, information about their environments, and a little more about the universe itself.

And even if you aren’t personally interested in getting involved, recommendations for useful resources or communities focused on speculative evolution would be very welcome!

Thanks for reading, and I hope this is an appropriate place to ask. :)

Im a student and im trying to remember the reactions.

i’m a freshmen taking organisms biology with a zoology concentration in the hope of working with or studying animals, i’ve heard it’s difficult to get permanent positions but i’ve also heard it’s difficult to get internships, experience, research studies, etc.

any advice i could get from people in this field

Hi everyone! I’m in the San Antonio area and have a bachelor’s degree in Biology. I’m currently working at Walmart, but I’m trying to finally get my foot in the door somewhere that actually uses my degree and gives me an opportunity to build relevant experience.
I’m completely open to starting at the entry level. I’ve been looking at positions like lab technician, laboratory assistant, research assistant/technician, specimen processing, microbiology, clinical research, environmental testing, and similar roles.
My biggest issue is getting that first professional biology/lab opportunity when so many positions seem to want previous experience.
Is anyone here working in biology, biotech, research, healthcare/laboratory science, environmental science, or clinical research in the San Antonio area? I’d really appreciate any advice on employers I should look at, job titles I may be overlooking, or places that are genuinely willing to train someone with a biology degree who is trying to break into the field.
I’m not expecting someone to hand me a job. I’m mainly hoping to hear from people familiar with the San Antonio science/biomedical job market who can point me in the right direction.
Thank you!
:)

I realize we've been breeding them for thousands and thousands of years, but even with other animals that may not have been bred for quite as long are no where near as physically different than dogs. It really is quite amazing that a Pomeranian and an English Mastiff are the same species. There are many breeds of things like sheep, cattle, and even cats. But again, none of them are as drastically different physically as dogs are.

I dont want sound too metaphysical, but its always been so peculiar to me that out of every species on earth, we're the only one with our level of consciousness. And it just so happens that our biggest companion animal happens to be the only one who can be shaped and morphed into pretty much whatever we need it for, even if it is certainly because of our doing. So why is it that we're able to do it with dogs so easily but not others?

Your brain may have once been two separate organs! 🧠

Scientists long thought the whole brain grew from a single group of embryonic cells. But a new study of mouse embryos found it actually develops from two, one forming the forebrain and the other the hindbrain. Similar trends in chickens and zebrafish suggest that over 500 million years ago, evolution may have brought two separate nervous systems together to form the brain.

That's the question
