pipeworks ASKED: hi i saw your post from last christmas in the population genetics tag on this here website and I was wondering if you had any resources for studying the subject? i'm taking a class in it next semester but i don't feel terribly prepared for it so I was hoping maybe there was some books/articles I could read ahead of time to help prep me for the class? thanks for any help you can offer!

thejunglenook:

I have included a few links and websites below for you to peruse. While it’s lovely that you are taking the initiative in preparing for your class, I would like to point out that it is ok for you to not be well versed in this subject. After all, if you were an expert you wouldn’t need to take the class!
Professors generally spend the first day (or even week) reviewing base information to make sure all the students are on the same page before breaking out the nitty gritty new stuff. So as long as you remember a few basic genetics definitions, I’m sure you’ll be off to a solid start.

That being said, if you have any questions about the information in the links below, in your class, or just about Biology in general, please don’t hesitate to ask. Genetics is a pretty awesome sub-field and I’m always happy to nerd out with you all. 

Suggested Reading (not a complete list!):


(xkcd)

Note: There are some pretty cool computer (FREE!) programs you can use for population genetics analysis (e.g. studying hybridized zones between populations, estimating pop. allele frequency, etc.) but let’s save that adventure for another day.

Although unnoticeable to those who pay attention to “the news"….we’re living in a pretty spectacular era of human history.

Seth Shostak - Senior Astronomer at SETI (Search for Extra Terrestrial Intelligence) - posed a submission that we, the human race, will detect an extraterrestrial civilization amidst the cosmos within the next 24 years. He’s so confident of this, he’s bet everyone (all 7+ billion of us) a cup of coffee on it.

It’s very easy to make fun of this, just like it also would have been funny to make fun of Magellan before he sailed around the world," Seth Shostak, a senior astronomer with SETI, told Congress. "We looked in particular directions at a few thousand star systems—the fact we haven’t found anything means nothing. This is like asking Christopher Columbus two weeks out of Cadiz if he’d found any new continents yet. We have to look at a few million star systems to have a reasonable chance." [Motherboard]

The reality is, we’re on an unprecedented exponential growth curve fueled by Moore’s Law, whereby advancements across multiple fields of science and technology are yielding new and transformative achievements, propelling us into a future of faster data processing at the helm of many disruptive technologies. A universal Rosetta Stone may not be attainable regarding our ability to generally decode transmissions from everywhere (and in any form) amid the past/present universe, but we certainly do have the tools for deciphering messages as we have from our ancestors’ hieroglyphics and artifacts.

With this in mind, read the referenced Motherboard article, and be sure to browse NASA’s newly published ebook by Douglas A. Vokoch, Archaeology, Anthropology, and Interstellar Communications.

The question I continue to submit when this topic is brought up, however: if we detect it, what will we do, and will we care?

We no longer live in a world where today’s news is tomorrow’s headline. News now is relative to weather…always fluctuating…when the storm is over, we go back outside. If it’s bitterly cold, we complain until it warms up. When we’re warm, the complaints pour in that it’s too hot. And similarly, when “breaking news” becomes breaking news, it ends up at the bottom of our news feeds and online dashboard threads.

Our society is plagued with alarmist tendencies. As X Prize Co-Founder Peter Diamandis reminds us, “the news media preferentially feeds us negative stories because that’s what our minds pay attention to. And there’s a good reason for that. Every second of every day, our senses bring in way too much data that we can possibly process in our brains. And because nothing is more important to us than survival, the first stop for all that data is an ancient sliver of the temporal lobe called the amygdala….our early warning detector, our danger detector. So given a dozen news stories, we will preferentially look at the negative news." This has more to do with how little attention we pay to how fast the technologically driven world is moving and how tremendous of a time we’re living, but it’s a worthy comparison to how we process that information to our advantage as a species which belongs to the cosmos…and to with whom we share this cosmic neighborhood.

Some may rush to say that we would plan some kind of hostile takeover. However, it’s unlikely we will detect a neighbor close enough to visit, let alone “shout across the street.”

So again, I wonder: what will humanity’s response be to the detection of intelligent life elsewhere in the universe?

Differences between male and female skulls.

Some of this stuff overlaps into ancestry as well but it’s a good quick guide 

In GENERAL, males have more pronounced, robust cranial features. It is important to remember that there is a lot of overlap in reality, and many skulls are ambiguous or have a percentage of uncertainty!

MD Lab: Hello, yes, is the CDC 

CDC: Uh, yes. 

MD Lab: Listen, I don’t want to alarm you, but we found some small pox this morning. 

CDC: Wait— wait what? You found smallpox. Like a person infected with smallpox? How and what. 

MD Lab: No, no, no. Not a person. Just a vial of it. Well, Carl found it. Erm, a few vials. Multiple vials of smallpox are in play here. 

CDC: I’m trying to get past the “found” smallpox here. How do you “find an eradicated disease 

MD Lab: Yes, Carl found it. He was cleaning out an old storage room and he discovered a literal box of smallpox. We assume it’s been there for a while. Honestly, I didn’t even know that room existed until we found it while moving some cabinets the other wee— 

CDC: Is the threat contained? Did Carl follow your lab’s procedure on discovering potentially hazardous material? 

MD Lab: Erm. He sorta just…chucked it onto my desk. But it didn’t break! 

CDC: You’re telling me a lab worker threw a box of smallpox at you. 

Carl? What? No, he’s Bill in accounts’ son. He’s been cleaning here all summer

CDC: ….ffs. Who runs this lab 

MD Lab: …uhhhh, the FDA. 

I actually work for one of those agencies and got a reassuring email from the Commissioner this morning. It was an FDA lab inside an NIH facility, and the CDC cleared everybody, no contamination risk and it’s all locked up again!

oxidoreductase ASKED: I've had male friends in engineering/computing sciences tell me tell me that I went into biology because it's the "softest" science and that I couldn't do what they do.

adventuresinchemistry:

anndruyan:

shychemist:

Ugh.

Its sad that this kind of attitude is still so prevalent. The concept of a field of science as more manly or that could be only done by a man needs to be destroyed. Gender roles make me upset. :(

I try my best not to think like this, but I’ll admit this mindset slips through once in a while. I try not to think like this because it happens in almost every STEM field.

I’ve even considered switching to pure physics instead of going for an astrophysics undergrad degree because I’ve had male colleagues tell me astro is popular among women for being the easiest physics. Screw that.

I just ignore that mindset and remember that “easiness” is subjective, and while there are “hard” and “soft” sciences and even though I’m considered to be in a “hard” science I can’t for the life of me remember biological concepts.

I hate the way that a lot of people dismiss biology as a “soft science,” which I think is at least partially because there are a lot of women in biology. Like women end up there because it is somehow easier than other fields, which is ridiculous, it’s just different than other fields. Because the all the various STEM fields are different from one another and use different methodologies. 

I tend to think that more women end up in the life sciences because there are more women in them. A lot of women gravitate towards fields where we feel safe, and I think that a component of that is having a substantial number of other women available as mentors and colleagues. Which is not to say that the life sciences are exempt from misogynist shitfuckery, because there is still plenty of that around, but its easier being a woman in a class with a substantial number of other women, rather than being in a class with only a few other women. So if you have any interest at all in bio you end up there out of sheer self preservation. Or at least that’s been my experience as a woman in both chemistry and biology.

I read somewhere (so feel free to question what follows) that (many) women want to pursue a career where they feel like they are helping or contributing to something. Which means they want a career where they are either directly working with people or where what they do will have an impact on people’s lives. Biology, more so than physics/chem/geosciences, allows for those career paths.

Also, the field of “biology” is so wide-ranging, that a basic undergrad degree preps for almost any grad degree program. There are way more options with biology - especially options that people know about - than there are with other fields. If anything, the other fields have a PR problem because when we imagine physicists and chemists, we imagine them exclusively working in labs doing esoteric work. People who pursue biology understand that there is a huge range in lab/field/in between work. It is easier to envision what a biologist does/can do and what they research.

In that regard, biology is more accessible, which is probably why bio programs at university are often so much larger than the rest of the science department.

Just a reminder:the natural diet of these birds is BONES. Not just bone marrow; actual bone shards. They pick up huge freaking bones from carcasses and drop them onto rocks until they get spiky pieces and then they swallow them. Their stomach acid dissolves bone.

look me in the eye and tell me that’s not a fucking dragon

And they aren’t naturally red like that. That’s self-applied makeup. They find the reddest earth they can to work into their feathers as a status symbol.

And they don’t scavenge other parts of carcases, just the bones. 85-90% of their diet is exclusively bone. Hence why it’s only a myth that these birds would just pick up whole lambs and carry them off. It’s not true, but in German they’re still called Lämmergeier as a result.

So metal
