I've recently realized the brain is a truly wonderous organ and I wanted to try to understand it - its structure, how neurons work together to control personalities and movement and memories. But it all seems so hard and overwhelming. Anyone know a good place to start?

Not sure if this fits the sub. This breaks the heart.

It happens only when I go to sleep and start making up fake scenarios in my head. They aren't about anything sexual or sexually arousing, just some random scenes about random situations. Only happens when I lay down and decide I'm not sleepy enough to already fall asleep, so I start making them up in my head and then the sneeze comes. I always sneeze precisely two times in a row and then that's it for that night.

Is there like some biology behind why that happens which is connected to my thoughts?

If I make the same scenarios up in my head during the day I don't sneeze, even if during the daytime I'm laying down, so is that somehow connected to it being nighttime?

ive recently gotten really into birds and ornithology, and id like to contribute something to the field while also contributing to scientific efforts in my region. a lot of specific middle eastern places are pretty neglected when it comes to detailed avian information, so i thought of writing a research paper that discusses the diversity of birds in southern saudi arabia by talking about all the species found there (according to avibase). would this make a good topic for a journal?

Hey everyone

Like many of you, my absolute passion is biology, and I really want to pursue it. My current plan is to go all the way to a Master’s degree, specifically focusing on biotechnology or bioinformatics.

However, seeing how frequently biology is cited as one of the most regretted degrees makes me very nervous. I don’t come from a wealthy background, so I don't have a financial safety net to just blindly "follow my passion" I need this degree to yield a stable, well paying career

Before I fully commit, I would love to get some honest insights from those already in the field:

- How difficult were your undergraduate and graduate studies? What is your biggest piece of advice for surviving the coursework?

- How is the hiring market looking right now? Do you predict things will improve or worsen over the next 5 years?

- Which specific field of biology is performing the best on the job market?

- Is the field stable? How much flexibility do you have regarding rwork, work life balance, or pivoting to other industries?

- Do you think it’s relatively AI-resistant?

I’m sorry about the amount of questions. I want to be 100% sure about my path, and if it doesn’t suit me I’ll stop looking into it now. I truly love biology, but I don’t wanna make it hard on my future self.
I appreciate any blunt, realistic feedback you can give me!

I've always found it frustrating that we explain complex biological mechanisms using static diagrams.

So I built Anima.

It's an open-source Claude Code skill that generates detailed, interactive figures covering neurobiology, pharmacology, anatomy and molecular biology.

One of the examples lets you switch between cocaine and amphetamine to see how their mechanisms differ at a dopamine synapse.

Another visualizes D1 and D2 dopamine receptor signaling with interactive controls.

It currently has six working examples, scientific references, interactive animations and optional WebGL/3D support.

The entire project is MIT-licensed, and the demos run directly in the browser.

Got a 91 on my bio test and last time I got a 69 which I was really sad about , knowing science is one of my f subjects. I just started high school and things are rough for me, but I am really proud and have improved since middle school and have all A’s.

Since cigarette smoking affects blood circulation, increases oxidative stress, and can damage hair follicles, could switching completely to vaping actually improve hair thickness or density?

I know nicotine still constricts blood vessels, but vaping eliminates many of the harmful chemicals produced by burning tobacco.

Is there a biological reason to expect thicker or healthier hair over time, or would the continued nicotine use prevent any noticeable improvement?
I’m mainly interested in the science behind this but also personal experiences.

Title says it all TvT

I love science, biology, zoology and ecology. Soooo when I heard there was a science fair a raised my hand immediately. There's going to be all sorts of college professors there looking at my work and it will be an awesome opportunity for my future.

One small problem... I have no clue what to do.

I've heard of all these kinds of highschool students making ground breaking discoveries for their science fairs but I dont know shit. My only plan was something ecology related but I have no clue what. Im good at art so no matter what bullshit I make it'll at least look cool but that's not gonna get the attention of college professors when they see my dorky looking ass. And, it's not like I could make some epic robot or do some crazy experiments, I'm broke!

Idk what to do or what I'm even expecting by posting this TvT

(Edit, it's due March 1st so I've got time :p)

Can someone explain what exactly urine culture does? is it possible to identify more than one organism? Why some people have to take two different antibiotics at the same time?

I am a Biology/Chemistry dual major within my University, and during my Sophomore year I took evolutionary Biology, which included some readings from Dawkins's work The Selfish Gene, which was extremely eloquent, and I enjoyed it greatly. I will admit that while reading Dawkins's work, I went down a bit of a rabbit hole in regards to the man himself, and discovered that he was once celebrated as a leading intellectual of the "New Atheism" movement and a very well-respected scientific communicator.

I attempted to look deeper into Dawkins's more recent work (as Selfish is from 1976, I believe), but it seems as if is scientific competence has become moreso as a 'science popularizer' than anything else, and he has been militantly spewing anti-religious rhetoric, which I personally have no problem with as I am not religious, but could be offensive to some individuals. I was then horrified by the man's recent alignment with more bigoted and hateful organizations and schools of thought, and saw that a lot of his comments on transgender people were quite disgusting considering his background and education.

All of this being said, do we still feel as though Dawkins's work (and his words) hold up? There are more than a few extremely important quotes from that perfectly summarize the fashion of science ("science is the poetry of reality"), and he has had some great contributions to the field of Biology, but is he still well-respected nowadays? I am curious because of how much I enjoyed his early work, and his thoughts on science.

Why are cancers so hard to treat? Because a tumour isn't a single enemy. It's a population of our own cells that keeps evolving, and every treatment we use is a selection pressure.

hi! i was wondering if anyone possibly had any input regarding a previous associate degree's credits and transferring those, and if anyone has some experience. i know this definitely depends on the college and classes, but just wanted any input or personal experience if possible!

i currently am on track to complete a criminal justice associate's degree in the spring, but have shifted to wanting to go to med school and complete a biology degree prior. originally, i planned to complete additional science and math classes to transfer for a biology bachelor's. however, upon further research i've found that miracosta community college has really good biology courses and professors. they also have a good transfer rate for uc san diego. my main question is if it would be a good idea to get another associate's degree and hope some credits transfer, or if i should apply to a 4-year instead of getting another associate's. i would prefer to attend a school in the san diego/oceanside area if possible, and have done minimal research since i'm a bit lost on what to do. any help is appreciated!

for context, i want to work as a dermatologist. i know this requires an extensive amount of schooling and is very competitive, so i'm looking for an option that offers good connections and education.

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.

I don't understand if Bio was shorter that maybe the contents will stick with me.

I don't like when ppl overexplains things....

Even calculus is easier that bio.

As the title says, i was reading about xenoestrogens and i cant find anything on phytoestrogens being toxic, whats so different between them and mycoestrogens?

I have been in research administration for 12+ years and I am currently an Associate VP for Research. One of the things I see constantly is that researchers at institutions without Pivot, GrantForward, or Cayuse subscriptions are on their own when it comes to finding funding. They manually check Grants.gov, NSF, NIH, DOE, USDA, foundation pages, and whatever newsletters they happen to be on. It is time-consuming and most of what they find is not relevant to their work.

I built a tool called CONVERGE to address this. It takes a researcher's profile, their field, prior funding, publication history, and research interests, and matches them against federal, state, and foundation funding opportunities. It delivers matched opportunities with a fit analysis so the researcher can see which ones are worth pursuing and which to skip.

I am posting here because biology faculty and postdocs, particularly at primarily undergraduate institutions, and smaller schools, are one of the groups most affected by this gap. NSF divisions across BIO, NIH institutes, DOE, USDA NIFA, and private foundations all post biology-relevant funding, but finding the right match is a weekly manual effort without institutional tools.

I would genuinely value feedback from working biologists. Does this kind of matching solve a problem you actually have? What would make it useful in your workflow? What is missing from how you currently search for funding?

The tool is live and free to try. Link in my profile. Happy to answer questions in comments or DM.

I got an essay to do about the anatomy and hygiene of the skeletal system. I've found a lot of stuff about the common conditions and diseases and whatnot, and they all describe the causes briefly, but I need a source "purely" about the factors that can affect the skeletal system, and I can't seem to find anything of the sort online. Can anyone help? Official verified sources, obviously. Thanks a lot in advance!

Okay I know i'm asking for homework help here but I want some cool topics for this class where we have to find a topic and come up with a proposal on how we would research it. Pretty please I have a few ideas down already: How is climate change altering the geographic range of Collared Pika, and what are the ecological consequences for the native species already living in that ecosystem?

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?

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!

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.

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.
