>Erlich and Zielinski stored six files into 72,000 DNA strands, each 200 bases long. The files included a full computer operating system, a 1895 French film, an Amazon gift card, a computer virus, a Pioneer plaque, and a study by information theorist Claude Shannon.

Does anyone know what the fuck operating system they're referring to? I looked all over and couldn't find which one in particular it was.

How fucking retarded are Americans? Like fucking seriously?

In other countries it's not even a fucking question, it's simply a problem.

We often talk about how dumb the brainlets are because it makes us feel better, but how about we talk about common misconceptions that even highly-educated researchers often hold? Here's a Nature news article examining five science myths that refuse to die:
http://www.nature.com/news/the-science-myths-that-will-not-die-1.19022

TLDR:
Myth: Screening for cancer saves lives, and we need to push for more screening
Reality: For the vast majority of screening programs, there was no decrease in mortality provided by screening. The decrease in mortality seems limited to fairly small at-risk groups.

Myth: Antioxidants Good; Free Radicals Bad
Mice genetically engineered to over-produce free radicals lived just as long as normal mice. A study in humans showed that anti-oxidant supplements actually DECREASE the positive benefits of exercise. Regardless of the documented effects of free radicals at a cellular and molecular level, at a dietary level, antioxidants appear mostly useless.

Myth: The human brain is large in proportion to body size
Fact: The human brain/body ratio is in line with what you would expect looking at other mammals. Textbooks often round the number of neurons to 100 billion, when it's closer to 86 billion.

Myth: Individuals learn better when taught in their preferred learning style
Fact: One-size-fits-all approaches to learning have been empirically verified to be more effective than 'learning style' approaches.

Myth: The human population is growing exponentially, and Earth is overpopulated (or will soon be overpopulated).
Reality: The human population is not growing exponentially, and is now growing at just half the rate as it was in 1965. There is also enough food, but it is distributed poorly because surpluses of cereal grains are used for fuel and for feeding livestock. Water is not scarce on a global scale either.

What do you guys think? I admit that the free-radicals one was a bit of a surprise to me, even though I am a cell biologist.

Lung cancer fag here, I went back and saw a new doctor today as I'm sitll highly concerned despite the clear x-ray if but he wouldn't refer me for a chest Ct scan on the NHS, and I can't afford to go private. He said I don't fit the criteria even though I have a persistent pleghmy throat now on top the loss of appetite for 7 months. He said he didn't believe I could have a loss of appetite as I have put on some weight (but this is only due to inactivity and binge eating on junk food out of depression over the way I'm feeling) and the X-ray was clear, he wanted to prescribe me antibiotics, I don't know what to do now, I'm still getting headaches too. I feel like I'm going to have to feign more severe symptoms or family history to get investigated.

in order to cleanse this board of brainlets and pop sci faggots, everyone post your favorite non-trivial formula for pi.

i'll start:
[math]\pi = \left[\frac{2\sqrt{2}}{9801}\sum_{k = 0}^{\infty}\frac{(4k)!(1103 + 26390k)}{(k!)^4396^{4k}}\right]^{-1}[/math]

This one's cool because its pretty obscure, and you only have to evaluate 2 (two) terms to get 16 (sixteen) digits of accuracy

Sup /sci/
I'am stupid, and english is not my native, so try to ignore my grammatics.
Question is:
Can we build [spoiler]for popularization of science and space exploring[/spoiler] on the moon a giant spotlight pointed to earth, and blinking somthing like "Make love, not war" in morse code?
Exactly:
1. How much illumination we need for our light source to be visible from earth? At least at new moon.
2. Can we create apropriate light source by modern technology?
3. Does it exists a power source for supplying that ligh source? I think about RTG.
4. If this installation can be created, can we bring it to moon with ony one flight with Saturn-V/SLS/Falcon Heavy?

Is deep learning and neural networks a meme?

Will it provide significant advances in AI and unraveling 'intelligence'?

Isn't it essentially just a fancier algorithm? Deep Mind and AlphaGo takes in inputs, uses them randomly and assesses it according to a defined (by a human) expected output. It then assesses how far away it is from that expected output and adjusts the 'weight' it places on certain inputs which is signified by a number value. That's literally all it does. In what way does this replicate human thinking?

Also, what do you think of Google's recent attempts and goals to 'oragnize the world's information and make it "accessible" (kek)'?

>literally scanning every book in the world (even against the wishes of the copyright owner) to "feed" to its AI (im not too sure how this works admittedly)
https://techcrunch.com/2013/05/08/google-book-search-and-the-world-brain-book/

>they expect this AI to have the most accurate prediction powers because it will essentially consume all available information which will help its parameter assessment

Do you think this is a realistic and feasible goal or all pipedreams?

Does it solve the Chinese Room experiment?
