It looks like there might actually be some kind of link between cell phone RF emissions and rare gliomas.
Any thoughts on a mechanism? Personally, I'm betting on some kind of blood-brain-barrier disruption that makes it slightly more permeable to carcinogenic compounds, which would explain the low incidence of the tumors in humans.

Idk but I'm guessing since it's non-ionizing radiation DNA damage is out of the question
and so the misinformation and lies begin
>>8103745
or how about not a large enough sample size
Anyone on /sci fool around with arduino? Make anything worthwhile? Is it worth getting into?
>>8103647
That's a /g/ thing. They even have a arduino general, sometimes.

Thanks, didn't know that

This is the stupidest thing I have ever read.
did you read the bible

Is that that book that they stole the Big Bang Theory from?
What cause time to stop in refrigerator from the relativistic point of view?
What would happen if I took an entire bottle of melatonin pills?

Nothing. It's not a drug, it's a diet supplement, you would piss it out in an hour or two.

don't do it senpai
Which private company or research institute has the most advanced AI to this day?
AI isnt real
its a scam by the Illuminati funded by bush
Bumping this thread, want to know.
>>8103408
My guesses:
Google Deepmind
Acxiom
Tesla
Is it true that
>top student spends 2 hours studying, learns almost all content
>you spend 6 hours studying, retain like 10%
>>8103333
No. Just fucking take notes and read your textbook dammit
yes
they're just more efficient and accomplish things in bursts rather than continuously.
>>8103333
Yes and no, depends on the person. I know a few bio majors who are like what you described. However a friend of mine has been top of the class and he studies like a champ. 5-7 hour sessions of reviewing notes, re-watching lectures, and re-reading textbook chapters over and over.
If you aren't naturally gifted then you get out what you put in. If you do shit all study expect shit grades.
Congratiulations, 'murrica!
Recently a so called "superbug" was found. This is a bacteria resistant to the antimicrobial drugs typically used to kill them, each year about 700,000 die from superbugs.
Why are superbugs a thing? Because there are more and more antibiotic agents each year. Say thanks to factory farming, say thanks to industrial farming where it's all about profit.
Basically with every new stuff we spray on them we exponentially speed up their evolution.
And now we face the challenges of a future where a simple...

The solution is really, really simple:
Mix multiple antibiotics together so that bacteria can't simultaneously evolve resistance to all of them. Crisis averted.
Also it doesn't make sense to stop prescribing antibiotics because you're afraid that the antibiotics you're not allowed to use might lose effectiveness.
Go to any local doctors office or hospital. There will be at least one infographic directed at patients or doctors urging the sparing use of broad-spectrum antibiotics. The Healthcare community recognizes the risk and is working to slow it with targeted antibiotics, for instance.

>Mix multiple antibiotics together so that bacteria can't simultaneously evolve resistance to all of them. Crisis averted.
Hahaha, no.
That's exactly what they do.
That's exactly why the crisis is coming.
Also nobody said we shouldn't use antibiotics at all. It's about the many places where antibiotics could easily be avoided.
Multiresistant bacteria are not caused by antibiotics, but by the excessive use of them.
Example:...

Hey /sci/ is the universe logical?
It's as logical as /sci/, op.

Nice trips
no it is probalistic
Do you think that psychopathy is linked with nature or nurture?
I do not believe that something so prevalent and well documented over hundreds of years could result from a (nearly even) combination of the two since differences between cultures, standards within individual cultures, quality of life, and parenting styles are always different and constantly changing.
>>8103078
You can have a genetic predisposition to psychopathy, but experiences during development can trigger a break with reality. There are cultural differences, of course. Look up rates of schizophrenia in first and third world countries. Yes its both.
I think it's definitely a combination of things, but nature is definitely a factor. I think our greater capacity for imagination and knowledge over the other animals which is also our curse. The more connections and complex a brain, the more ways it can go wrong. Just the slightest misalignment can lead to all kinds changes.
>>8103078
psychopathy is a myth.
Psychology is not a science.
I'm trying to calculate something but I don't know exactly how to set up the equation because I don't normally work in this field and I'm pretty new to STEM in general, only just half way through with my BA in chem.
Anyways, I'm trying to figure out what the effect of trump's wall getting too tall would be on the center of gravity of planet earth.
Let's take F to be the approximate height of the wall as originally intended.
However, the real height of the wall will not be expressed simply as a function of F because every...

Make wall inflatable, fill it with helium, it can now go up to space changing earth's CoM by fuck all.
Negligible.
>>8103026
But what if somebody popped it? wouldn't the entire wall come down?
To all the dumb physicists in here trying to give ontological character to their mathematical discourse (which is only descriptive of relational properties):
"But hitherto I have not been able to discover the cause of those properties of gravity from phænomena, and I frame no hypotheses. For whatever is not deduc’d from the phænomena, is to be called an hypothesis; and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy." -Isaac Newton

/sci/ is there ANY food, drugs or drinks that can help increase your intelligence? I'm doing those brain puzzle games but I think I hit a plateau.

Nice try memer.
Caffeine and amphetamines can give you a small boost, but there is not magic compound to make you smarter. Use sparingly of course.
So I made a hypothetical planet called "Cerza" which I think would be just great for life, try and find any flaws in it.
Cerza is a water planet with an average global temperature of 500 degrees Celsius, so I guess steam planet is better. It's 2 times larger than Earth and its atmosphere of water vapor is 10 time denser. Its home star is the same size as ours so to achieve its heat it would be about 3 times closer to its star than ours. The dense atmosphere would act as a sort of buffed up ozone layer for the planet, defending it from harmful radiation...

Yeah, because fuck proteins, let's jump directly to autobots.
>>8102768
> average global temperature of 500 degrees Celsius,
It's completely sterile, and inhabited by nothing larger than carbon dioxide molecules.
>>8102768
Ever thought about the fucking temperature, pressure and gravity making a whole lot of chemical processes necessary for biological processes to be fucking impossible to achieve?
I mean if you want a giant petri dish where you can just grow some retarded version of a single celled organism then yeah, why not?
I have an idea to make ionocraft pic related practical, but I don't want to accidentally an hero fiddling around with high voltages.
whats some free physics simulation software that has good electric field and fluid dynamics support.
>>8102607
ayy lmao
can't be done, use a propeller boy.
>>8102607
High voltages mean jack shit. A simulator like that is expensive as fuck and there are no cracked versions. Besides that, you would need a little beast to crunch that shit.
Just do it, and respect ohm's law for your own security.
>>8102771
>Your listed concern proves that you don't know your shit, so just do it and be safe.
I just got done with learning C++ this past semester, but I'd like to get better at coding by practicing. It's just that I don't have any inspiration.
What are some simple project ideas I could work on?
PS: No "Project Euler" stuff. That's good practice, but it's useless once I'm done with it.
