does anyone have a ForumBiodiversity login? (registration closed.) can they repost the pictures?
has anyone seen other direct-to-consumer DNA test data from Australian aborigines?
>>7779069
Bump for interest.
>>7779696
There's very little published genomic data from Australians at present. Intredasting that the best fitting models were all Papuan + SE Asian. were there migrations into Australia that bypassed New Guinea?

Kek. Good luck with all of the writing you'll have to do.

I had the highest grade in my English class actually.

Writing a scientific paper on a topic you love is a whole lot different from writing a paper on some socialist propaganda in the form of a book which was shoved down your throat by a cultural marxist professor.

Would aliens create the same mathematics as us?
Probably not.
YES

different notation at the least
Place your bets, people.
Will it be delayed, blow up, crash on landing, or work perfectly.
Or, if the comments on NASA's facebook-page are true and space is just a carped made by the government to fool us for some reason and rockets dont work in vacuum, what will happen?

i shit you now, those comment sections are full of people rambling on about how everything from how Apollo was fake to the Van Allen belts being gods way of stopping people from leaving.

Why is the immune system so unbelievably retarded?
It's actually very complex, but microorganisms are too good at adapting.

Go back to /b/, someone already got the get. You can leave now.

No, I'm saying why is it so fucking stupid it attacks the body like ALL of the time?
I have several autoimmune diseases and holy shit evolution sucks if it can't figure this shit out.

Hello, I have a few questions about black holes
Me and a friend of mine, are working on a presentation about black holes.
We've thought of a few good questions we wanted to answer in our presenattion.
Most of them we could answer ourselves, but we're struggeling on anwsering the question:
What are the requirements for a star to become a black hole?
OP here, about the question, more detailed question: Why dont the stars become white dwarfs or neutronstars?
From what I've read, it needs to be a star several magnitudes larger than our sun with a massive amount of Iron at its core. This contributes to a point of density and describes an incredibly high pressure core during the super nova that can collapse into a black hole.
Our sin cant do this and in a few billion years, will die a white dwarf.
>>7778769
White dwarfs do become neutron stars, which are stabilised against further collapse by degeneracy pressure. However a white dwarf 3 times heavier than the sun will always collapse into a black hole (cf. Tolman–Oppenheimer–Volkoff limit).
Since a space elevator is out of the question, due to the fact humans suck at making materials strong enough to do it, why not make a space mountain?
Just build a mega mountain that reaches to or past the Karman line. Then people can WALK to space!
Imagine a 100km high man made mega mountain (Mount Everest altitude is only 29km high)
Edge and Base Cone Length 115.47km long (based on an equilateral triangle)
Volume: 349,000km cubed/83729.5527 miles cubed
Weight: 92.4 million megatons (0.0000015% of the weight of the Earth or 184.8 billion 'BelAZ 75710'...

Material science isn't simply there to build such an object.
Carbon nanotube production is still in its infancy. Metallic foams and programmable buckyballs is, again, still being worked on.
And despite ambitious attempts by billionaires to build arcologies, we don't have anything taller than what's sitting in Malaysia. We don't have best building practices down yet.

It is. You literally just pile shit up in the form of a giant mountain. The real problem is that it will sink. That is, make the entire Earth's crust sink in that spot. The more you pile, the more it sinks. The only way for it to work is to have a completely cold core in the Earth and everything be solid under the crust. You'd always end up with a Mount Everest-sized tip sticking up out of the crust regardless...

Two problems:
1) We can't build anything remotely that high. The square cube law (the same reason an ant can lift many times its own weight and you can't) applies to structures too. Mount Everest is already pretty close to the theoretical limit for how tall a mountain can be without collapsing under its own weight. That's why planets are round in the first place! If you built it out of some exotic material you could get higher, but not THAT high.
2) Even if you could, it wouldn't make space travel easier. Getting to space is about moving fast,...

Is there any possible way for a man to become sterile, in a short period, without developing cancer. For example using some kind of medicine
cut it off
>>7778740
what the fuck is that?
and yes, there are drugs which suppress testosterone production, which will make you sterile, amongst other things

Colostomy. That's what you intestines looks like when sewed to a hole in your abdominal wall.

Clarkson is obviously very intelligent I don't understand what point you're trying to make. Acting like a Jester is literally his job and he does it well.
Why do people used odds instead of probabilities? It just seems like a convoluted way to express a simple idea. It's not intuitive to me and I have to do calculation to get the probability so I can understand what they mean by the 'odds'.

How do I become a Botanist? I just watched The Martian and Matt Damon was really cool! :D It inspired me to become one. How do I do that?
Are you fucking retarded.
>>7778158
Either you are retarded or this is bait
Pursue an undergraduate degree in biology. If a school by you has an actual degree in botany, go for that. Take upper level plant biology courses and try to engage in some kind of plant research while there, if possible.
Pursue a PhD in Plant Biology, or another field of biology, using plants as a model system or an organism of interest.
You're welcome.

So I'm an Ausfag, 2016, year 11 in few weeks.High achiever, straight A's in all subjects. Next year doing Math b&c aswell as physics. I know the jump to year 11 is huge, what I want to know is, how hard is the calculus side of year 11? Australians Pease respond!
Please Aussies?
As far as I went (I did VCE) was differentiation, limits, and a bit of integration of simple functions. No trigonometric ones.
I'm going into year 12 this year. The difference between maths b and c in year 11 is insane, if you're any good you should be able to achieve close to perfect marks in maths b without study but in order to do well in maths c you'll need to work.
Are high energy electronic weapons like rail guns and lasers actually the future of warfare, or is that SciFi garbage?
Will chemically propelled weapons remain superior?

We already have functioning laser weaponry.
