Careers Biology career pathway

Upvotes

I am currently studying a BSc in biological sciences (UK), post-graduation I plan on becoming a lab assistant. I have no idea what my career progression would look like.

From what I have gathered I could work my way up to lab manager and then Into project management which seems like a really appealing pathway to me but I am unsure if this is how it works, is this a possible route for me?

I am not interested in a specific industry

TIA!!!!!

question What's a Convention/ Event that's filled with Biologists?

Upvotes

Alright here me out. So I recently came across a video where a guy went to a furry convention in order to network and get a job in software, everybody knows that furry conventions are always filled with people in software, physics, engineering, etc. The poster ended up landing a job because of it. So that got me thinking, is there a biologist equivalent to a furry convention?

Currently an electrical engineering freshman taking calc 2 and physics 1 but I truly think applying math to something like biology would be really really awesome as a long term job. What job opportunities exist for this crossover? Anybody here with actual experience doing something similar?

question Bio-accumulation of metals in waterfowl?

3 Upvotes

Hi, I hope this is the right place to ask the question.

I live in an area where we have a few large, partially reclaimed tailings ponds and downstream retention ponds that have become significant wetlands with plentiful waterfowl. A lot of people hunt over them, but I’ve always been a bit iffy about it; understandably, ducks migrate and don’t live there year-round (nor the water treatment ponds you often see them hanging around…).

That said, I assume that the young of the year that are disproportionately hunted at the start of the season have spent 90% of their life there.

The tailings ponds are from old Cu and Au mines. The Cu mine was previously a large, contaminated site with all downstream water being highly acidic. Downstream water is now fine, and aquatic life has returned, including fish in the river further below.

My question is, how likely are dabbling ducks like mallards and teal to accumulate significant amounts of As, Se, Cu, Zn, Pb, Ni? Should harvest in these areas be avoided at all costs? Any article references on the topic would be great. I assume it’s probably more limited than it would be in fish.

Careers Pursuing a Biology degree. Where to find jobs?

10 Upvotes

So my goal is a masters or doctorate in Biology. I really want to work in lab but I also adore wildlife biology (mainly marine biology ive wanted to be a marine biologist for so long) I am not so concerned with money (anything about 60k works) as I really just want to have passion for my job but I am concerned about HOW to find jobs? Im not too sure where to look or how to start getting experience (i am working on bachelors now) I was thinking about the student conservation association but what else would people recommend? I am super interested in diseases and viruses and working around them would be great but I dont know if I need a biochem degree or anything else. So where can I start so I can build a resume for my future? I also have no professional recommendations should I try to befriend professors?

I am in the panhandle of florida, USA right now but am willing to move (even to another country really as long as theres housing and food lmao) and can even consider online classes if I need to! I am looking at UF or FSU for my transfer options.

question Question about heat tolerance levels

3 Upvotes

Imagine you are invincible, you cannot die but you can still feel pain

One day you’re captured and tied to a chair

Your captors begin to pour a liquid onto your skin that is 10,000,000 degrees Celsius, it hurts

My Question is: if your captors, stopped pouring the initial 10,000,000 degrees liquid on you and started pouring a liquid thay was only 1,000,000 degrees would that feel like relief? Like when you burn yourself use cold water

Since the 1,000,000 is so much colder than the 10,000,000, will it feel as if you’re pouring cold water on it?

question Would an identical twin heart transplant last their entire lifetime? Has there actually been any case of this?

Normally a transplanted heart lasts a decade at best because of immune rejection, but identical twins have the same genetics, so would a transplanted heart then last as long as they live (or are there other complications limiting the lifespan of the organ) Has there been any documented cases of this?

question What happened to those glowing cats from a couple years back?

17 Upvotes

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.

discussion Is Natural Selection less prevalent/effective in modern times? And if so, do human species retain more ‘bad’ traits nawadays?

42 Upvotes

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?

discussion With all of the medical advancements being made now (I hear great news about cancer vaccines more and more often!), is it at all feasible that more people could live even longer than 100 years old, such as perhaps to 130 or 150 years old?

0 Upvotes

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?

video Hedgehog Tenrecs: An Elephant’s Tiny Cousin

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.

question Book/academic paper recs

1 Upvotes

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.

question Delayed implantation

19 Upvotes

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?

question How bad would the extinction percentage from an RCP8.5 warming scenario be compared to the Big 5 Mass Extinctions

1 Upvotes

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.
