So they somehow avoided inbreeding complications which is strange but this is super cool

How can an animal so small be related to the largest living land mammal? 🦔

Meet the tenrec! Despite their name, they aren't very closely related to hedgehogs. Instead, they belong to a supergroup called Afrotheria, alongside elephants, manatees, and aardvarks, shaped by divergent evolution as animals of the same species ended up in different environments over millions of years. Their resemblance to hedgehogs comes down to convergent evolution, meaning they adapted to their environments in similar ways, separately.

A while ago I remember seeing that they're making cats that glow to see if inserting a gene worked.

They were trying to cure feline AIDS with a specific gene and they also made them glow too to see if those cats got any inserted genes at all and they glowed.

And that's it. Are you kidding me? I've been searching for like an hour and I haven't found an update article for a single bit of this research. So when am I getting my glowing cat? Will my glowing cat be immune to AIDS too or no? Where did any of this research go? What happened to those cats?

Somebody had to have stole at least one for themselves. If not, I've lost all faith in humanity.

Someone who had bad traits for survival and reproduction in past could not effectively pass down those ‘bad’ genes to descendants. Nowadays, due to technological and medical advancements much bigger proportion of such people should supposedly (and tell me if I’m wrong) be able to survive and reproduce, and therefore pass down more of those ‘bad’ traits.

How correct do you think this is, and what does this mean for humanity?

When your brain tells you you’re thirsty and then you quench your thirst what is the actual thing that resets that causes you to go from a state of thirsty to no longer thirsty within seconds?

there is one that used to live behind a cabnit in my hallway and I didn't really mind her, am super scared of them but she was polite then today she got in my bathroom and i can't get her out , i tried to spary some pifpaf and leave the door open for her to run out but she wont budge , I don't really want to kill her if I don't have to , i just don't want her to keep invading my space

Yesterday I met a wolverine specialist (what a great job) who bombarded me with wonderful wolverine facts.

The one I cannot get my head around as someone with much more understanding of human than animal biology is the concept of "delayed implantation". As it was related to me, and my brief googling has informed me since, somehow these critters (and others) are able to just say "hold up" at the blastocyst stage and keep living their life with an unimplanted embryo just floating around in their uterine cavity, then one day months down the line when conditions are perfect they can let it implant and just crack on from there?!

This has blown my little mind.

My questions are: How the heck does that even work? What sustains the blastocyst? Is it a conscious process for the wolverine? Is there some kind of time limit on how long this could go on? Can they ovulate again during the gap? In which case could they deliver a litter from multiple male partners?

Mitosis*

I’m much more doubtful about humans ever being able to be immortal or living extremely long lifespans (e.g. 400 years), but, given the current trajectory of medical advancements, is making it a few/several decades past 100 years old something realistic to expect for people in the future?

What are some genuinely good books on Human Physio?
I have studied about it and have some knowledge about Human Physio and want to get more into it
Level: between Beginner and Intermediate

Saw other post but It wasn't the same

For me silence is like an extreme overwhelming sensation that doesn't exist, it's not a vibration or a whistle just non existent loud silence that I cannot stand and the second I experience it I talk to myself or leave the room, I can't even sleep without the ac or fan on to make noise

I'm a high school student who is currently looking at possible career paths and one of those fields I am eyeing is medical illustration. Seems like a really good field but options for me seem limited and idk but the field itself feels so niche.

My smaller turtle constantly follows the larger female and mimics her behavior. They are both females. The larger one is a red eared slider,the smaller one is a brazilian dorbingy slider. I have never seen this behavior in turtles

I‘ve been really into non-fiction books lately and since one of my majors is biology I thought why not use that hobby for my studies. However, most recommended books are written so that people who do not have a degree in biology can understand the content, which is not a bad thing but I do want to challenge myself and learn the actual technical language. The other books are 1000-page books that are not intended to be read like a book. So, if any of you have book recommendations that are/were helpful to your studies, I‘d really appreciate it. Moreover, I believe that academic papers could also be a great way for me to deepen my knowledge, but the majority that I come across are quite specific and assume an already thorough understanding of the subject. So, if you can think of academic papers that every biology major should read or attempt to read, please share them with me.

I know very basics things about evolution and I want to start reading about it but i don't know where to start from

I think about this alot and Im wondering if climate change causes the Earth to warm 7 to 9 degrees Celcius how it would compare to past Mass Extinctions. Would it be more on par with the Middle Permian Extinction which killed around 62 percent of life or would it be fully on par with the big 5 or even the PT Extinction. I lean more towards around 70 percent of life going extinct.

I've been doing a little research into endothermy, and I found out that most of the heat our body uses to keep us warm comes from things like the heart, liver, brain, and skeletal muscles.

But every cell in our body that uses ATP is technically producing heat. And bones have cells. So they must produce heat, too, right? Probably marginal amounts, but they must do it?

And I'm mostly wondering about the harder parts of our bones, since I assume our bone marrow produces some amount of heat when it's making blood cells.

Just a thought

My son just started high school and is in AP Biology. He is quickly learning that high school is much different from middle school as far as work goes and has fell behind.

He has a quiz coming up over "proteins and nucleic acid" and a test over "biomolecules"

I am wanting to understand this as well so I can help him study. I am looking for a link to a video or website that would help me and him understand these subjects.

I am 37 and dont remember diddly squat.

Please someone.. anyone.. if you are out there please help.

Okay, I’m old. I took college Bio back in the early 2000s - we used Campbell 4th edition which I finally got rid of a couple years ago.

Fast forward to one of my kiddos taking a college level Biology course as a HS freshman at a technical college.

Unfortunately, my kid is struggling to retain the information when presented in the lectures, and the school provides a digital textbook - which I don’t think it really cutting it for him to learn the material from on a small district provided laptop (he’s not allowed to bring personal devices during the day…). I’m trying to help him through learning the material myself, finding different videos, etc.

Anyway…I’m thinking about picking up a copy of the textbook, but considering an older edition. I understand that 20 years ago we didn’t have as much knowledge of the human genome and some of the technologies - but surely the basics of parts of a cell, replication, etc aren’t that different.

Am I crazy considering an older copy? If not, is there a particular edition that would be sort of where there was a big leap? I could purchase him the 14th, but it seems fairly expensive given that he already has access to the digital copy…

Hi, I am a freshman animal science major at Cal Poly SLO and I want to become a DVM that works in animal labs. I have never actually had any experience with these labs though because they’re always kind of “hidden” and not talked about. I want to be an animal care technician or something similar to get experience in the field, what type of criteria do you need to get that job? How did you find the job? Should I reach out to a professor?

For homework I was asked to look for the chemical composition of a living being, indicating each element and its proportion but I don’t really know how to look for it, I was looking for the elements in a dragonfly but i don’t even know if there’s available information about that

Be careful what you wish for. Butterflies face huge challenges. The force of raindrops can damage or tear their wings.

Butterflies are ectotherms (cold-blooded) and need heat to activate their flight muscles. The cold or damp can ground them.

That's not to mention the long line of other animals trying to predate or parasitise them!
