A Beautiful Image showing the Evolution of the Eye from Visual Capitalist

Someone said they're tadpoles, others said their mosquito larvae. Does anyone know what they are and why they're swimming like that?

Hey all, I made this app that helps you keep your information organised together, no matter the platform. I hope it has some use for you guys! Made it completely free to use, so do check it out if you're interested. I made a quick demo on youtube that now has 1000 views which is pretty cool, and also the App Store link is here for you to download! Feel free to ask any questions!

Just saw two pigeons getting it on on my windowsill. They were so sweet afterwards. They stood leaning on each other for a while and then took turns preening each other's neck and head feathers. I also know that intercourse is sth that the females of some species such as ducks or cats try to avoid and escape at all costs, so this scene made me genuinely curious: which species display affectionate and/or caring behavior right before, during or after mating? Are those also species that mate for life? Or are there also non-bonding animals who display this sort of behavior? (I understand that there will be exceptions to every rule, I'm asking about what is considered typical/default, unless you wanna tell me of a notable exception as trivia, which is also cool.)

Hello, I am about to graduate with a degree in biomedical science and I am interested in molecular biology and computational biology. The thing is I like conceptual thinking and creativity and dislike repetitive work, procedures and troubleshooting. Would computational biology be better for me?

As most of our body is made up of many different types of bacteria and microorgaisms, How do our immune system distinguish between 'good' and 'harmful' bacteria in our body?

From the prepesetive of the immune system, what consititutes as 'good' and what is considered as 'bad' bacteria?

I would think that as long as bacteria lying inside our body dosent do harm or damages our tissues and cells, the immune system considers them as 'good' bacteria, whereas if the bacteria does harm to tissues and cells, then the immune system would consider them as 'bad' bacteria?

Due to the semi-autobiographical nature of the novel, I can't tell if that's something the author actually witnessed or if it was a dramatization.

Edit to add the passage: "Right next to me a lance corporal gets his head blown off. He runs on for a few paces more with blood shooting up out of his neck like a fountain."

Basically create a organism, doesn't have to be a fungus really, could be anything, that is seperate but operates by taking nutrients from a host organism like a parasite, but produces a key nutrients someone is lacking, IE insulin, estrogen, ect as a byproduct of it being alive.

or even on another note, using fungi as a electric bridge for signals in the spine of patients with spinal injuries. or even to add extra space or preprogramed information that can directly "plugged in" into someone brain, like inserting a disk into a computer.

Meet C.C., a legless amphibian designed for burrowing and aquatic living. With tiny eyes covered by skin and a paddle-shaped tail, its underground lifestyle makes it seldom seen, leaving much about it a mystery to scientists.

I really hope this is allowed to be posted here, but I’m reading this problem and I truly do not understand the logic behind the answers. My professor mentioned that a=O, b=Z, and c=I, however, I don’t understand how he got that. I understand b=Z a little, but not the others. Anybody want to test their logic and knowledge skills and have a conversation about this? The “/“ on some of the symbols mean two seperate chromosomes so that’s where the cis/trans genes become a thing.

Bro, I just learned about how hot the pistol shrimp’s shot can be and that’s something I never wanna be around along with the two types of mantis shrimp Why are there so many types of shrimps that are so strong

Where does it get the information on what amino acid to put together so that the antigen can "fit" in the antibody.

I just saw a video of a hippo chewing a coconut and I noticed that even though it has teeth it just pressed on it with the top of its mouth instead of using its teeth. Why are the top of their mouths so hard? Why do they have teeth if they don't use them?

Hi, I'm want to study biology, so I was asking myself how much chemistry do I need to study biology? Thanks on advance

Margarine is promoted as a healthier alternative to butter as it contains polyunsaturated fat instead of saturated fat. Furthermore it also contains plant sterols, which compete with cholesterol for absorption across the intestinal cell membrane, leading to reduced cholesterol uptake, thereby improving cardiovascular health.

However, there has been a concern about trans fats in margarine for the past few years, and since then the manufacturers have made an effort to remove trans fat from them. But how do I know if there isn't any trans fat? Sure, the manufacturers do provide nutritional information which details any information about trans fat. But how credible are they?

Most mammals have babies and instinctively know exactly what to do once the babies are born.

Some instinctively prepare for their babies to be born well ahead of time by gathering nesting materials and building nests.

However, if a 12 year old boy and a 12 year old girl make a baby, then that's just as far as their thought process on that situation goes. There is no instinct involved except for maybe the sex part but even that doesn't seem like instinct and more of a result of social influences.

Hi everyone!

I have graduated with my Bachelors in Biology and I’m seeking some advice. I was originally pre-veterinary, but have changed my track and looking into Forensics now. Interested in helping people and seeking justice for those who have been wronged in life. I feel forensics would be very rewarding, thinking more of the lab side of things or even autopsy tech . But, I do know forensics entry level jobs can be hard to obtain and you may need a masters degree or move states away to find a job opening. I am currently in a general diploma program for forensics and almost done with it.

I’ve also considered maybe sonography program or MLS degree... So I am still using my bio degree towards my career and can further myself into another program. I would still do something rewarding and get to help people in some sense. I am 27, so I know that I am still young, but mentally feel I’m running out of time. I’m trying to keep my options open

I really want to get into a career track and would like to hear some personal stories of what you did, or if you have any suggestions for me based off my current interests what my best move would be. I’m 90k + in debt from just my Bachelors and want to make smart monetary decisions going forward in life.

Thank you for any advice or taking time to comment it means a lot!

Like I read somewhere where it said eradicating mosquitoes will be quite an achievement in the field of healthcare to eliminate certain diseases, and people are working really hard to accomplish it. But doesn’t it clash with the “preservation of biodiversity” principle? Who knows, the mosquitoes might be doing something else which is important to the ecosystem, and hasn’t been understood by us yet? Or maybe they just keep the human population in check?

Why do aging occurs if its detrimental to the survival of a species?

Isnt it counterintitive that evolution selects for aging when its clearly detrimental to the survival and reproductivity of a species?

Shouldnt evolution selects for genes against aging so that the speices remains strong and fertile throughout their lifespan greatly increasing their chances of survivial against diseaes and predators?

Hi… my dna test shows only one G (-/G) for MMP1 rs 1799750 ( I believe that means hemizygous? One allele missing?). My dna test blurb has given me implications for 1G/1G, but this would be incorrect as I only have one copy not two, but can’t find anything online to explain this!

How do we know the complimentary DNA sequence of the primer that attaches itself to the 5' end of the DNA template strand. We use Sanger sequencing to know the sequence of bases in a particular DNA strand, then how are we synthesising the primer in the first place without at least some of the sequence to create the primer which is complementary to the 5' end?

Hi!

I have a bachelors degree in biology, but I am currently looking into potential masters programs. I’m interested in both bioinformatics/statistics as well as genetic counseling, and I’m hoping for some insight to help make a decision. I would ideally also like to work from home in the future. Any opinions are greatly appreciated, thank you!
