How Venture Capitalist Peter Thiel Plans To Live 120 Years
The paleo diet might end up being silly, but just once I'd like to see this discussion without the kneejerk "20-30 year life expectancy".
If you made it to 15 years of age or so in a hunter-gatherer society, you might reasonably expect to survive to 60. As an infant, you are highly likely to fall prey to disease or poor care, pushing the life expectancy at birth way down on average even though those deaths usually had nothing to do with the diet of a mature adult in the community. Adults didn't usually drop dead at 30 from poor nutrition.
Study: Body Weight Heavily Influenced By Heritable Gut Microbes
Diet doesn't really change the microbes.
That is not what recent science indicates at all.
"Diet rapidly and reproducibly alters the human gut microbiome", Nature 505, 559–563 (23 January 2014) doi:10.1038/nature12820
"Here we show that the short-term consumption of diets composed entirely of animal or plant products alters microbial community structure and overwhelms inter-individual differences in microbial gene expression. "

Ask Slashdot: Finding a Job After Completing Computer Science Ph.D?
This assumes you're getting hired at a consultant position in an MBB (McKinsey, Bain, BCG) style firm because that's what the GP was suggesting. By "consultant" he means management consulting; the major firms in that field actively recruit Ph.D's, and definitely not for the sales skills.
It's a very distinct suggestion from being a consulting computer scientist, which the GP was never suggesting.
The Last Three Months Were the Hottest Quarter On Record
The ozone layer is regenerating because the use of CFCs was regulated. If we had continued to pump more, it would overcome the sun's rate of production. Therefore I'm not sure of the point you're making; it's a success story for regulation. If we just forgot about it and didn't regulate, it wouldn't be regenerating fast enough.
Marvel's New Thor Will Be a Woman
Neither of those examples are gimmicks. A gimmick would be an extraordinary occurrence just for the sake of having a female character. If it's an ordinary replacement and it happens to be female I don't see how it's a gimmick.
In the former, it's been established that the "Robin" position gets passed around frequently. There's half a dozen of them. What's gimmicky about one of them being female?
In the latter, Peter Parker was replaced in the Ultimate universe because he *died*. This might be gimmicky in the normal Marvel Universe, where the status quo remains forever, but in the Ultimates universe, iconic heroes die all the time and stay dead. Beast drowned, the Wasp was eaten by the Blob, and so on. Spider-Man wears a mask and is easy to impersonate, what's gimmicky about any random kid with spiderish powers taking up the name?
Predicting a Future Free of Dollar Bills
Actually, can you explain to me the benefits of a $1 coin to the user? Fine, it's more durable; I don't really care, I rarely accidentally destroy $1 bills, so that benefit accrues solely to the mint.
I get the odd comment from European friends about how silly the dollar bill is, which I don't understand. In practice, my experience in the Euro area and in the UK is that my pocket gets so frigging heavy and awkward. Meanwhile I can get a weightless stack of $1s as change in the US. Sure, they could make the dollar coin tiny, but now it will be confused with a dime or nickel, requiring an entire reset of the whole coin system relative sizes and weights.
Continuous System For Converting Waste Plastics Into Crude Oil
I'm all for eliminating waste, but if the net effect is that we're removing plastic from landfills and emitting it as CO2, that's not terribly different from digging up crude oil and emitting it as CO2.
Now, I'm sure there's some sort of multiplier here that makes it a bit better - perhaps the plastics are a cleaner source and less energy will be used to process it - but currently this carbon is sequestered in an inert if unattractive form whose dangers are mostly localized.
Strange New World Discovered: The "Mega Earth"
A little bit pedantic, but it certainly matters as they vary as different powers of the radius. Having 2.3 times the radius would be almost 12.2 times the volume. If the volume was only 2.3 times the Earth's volume, then the radius would only be 1.32 times larger.
'The Door Problem' of Game Design
Let me guess, you only ever play sandbox games?
The summary questions are essential questions to answering what kind of game you want to design, and you explained the consequences of ignoring them perfectly in your commentary. A game is a combined experience and challenge. That experience needs to fundamentally be finite, if only because you have finite designer time. What you have to do is make the experience finite without throwing arbitrary restrictions at the player when possible. Yet I wouldn't want EVERY game to be set in a featureless canyon rather than a city just because I can't open every door.
Sandbox games aren't bad, per se; it's a good design challenge. Frankly though, I've never played a sandbox game that didn't feel a little soulless (Nethack, GTA, Minecraft, etc.). I prefer games with some narrative thread or plotline, and that inherently will mean balancing the experience and interactivity you want to provide. If I can't open a door that I think I should be able to open, that is a failure, but it's not simply that they shouldn't have put a door there or built a room.
Is Germany Raising a Generation of Illiterates?
I don't think you need to be torn between the two. Even though in many cases strict grammar isn't necessary, where would we be without formal rules to provide a sliding scale?
If I fail to communicate effectively in some context, grammar provides a clear standard I can return to in order to iteratively improve my communication. If everyone had conflicting standards, I'd have no shared toolbox to use. Two mathematicians may be perfectly able to talk about their work in common vernacular; if it starts getting miscommunicated, though, they have a shared formal grammar of logic within which to make things clearer.
Doctors Say New Pain Pill Is "Genuinely Frightening"
This seems a little better than that, if I'm understanding it correctly. The drug would never be mass-produced if its approval is revoked, and it's doubtful that the company would let its production method out AND that it would come to someone with the capabilities of producing it illicitly.
It's hard to have a black market if no one makes the drug for any legal use.
How Voter Shortsightedness Skews Elections
Let me play devil's advocate here. While we can ascribe that to "dumb voter shortsightedness", wouldn't it also be true to say that if you can ascribe economic performance to a president at all, their effect on things would be much more heavily weighted towards the recent past anyway?
Early term performance would likely be out of their hands, and my assumption would be that they want to get reelected and would try hard to eke out some benefit before election season. If you can't bring out the big performance before the election, perhaps you don't have anything to offer.
Of course, imagining that your choice of president has a greater effect on your wellbeing than state and local elections or larger economic trends is a bit weird to me anyway.
How Farming Reshaped Our Genomes
This is just my take. The average intake of the American consumer has increased steadily, I believe. However, weight gain happens at the margins. If you eat 2200 calories a day and burn 2000, you are gaining weight twice as fast as someone who averages 2100 with the same burn rate, even though your intake is less than 5% higher.
As the average intake passes the burn rate, a little exercise helps. However, with a small percentage-wise increase in your intake, you can double or triple the amount of exercise required to get back to equilibrium. My guess is that in the 60s and 70s, adding exercise worked for many people. Now, the necessary exercise is much, much higher and caloric restriction is necessary in a way it wasn't for the average person 30 years ago.
The "Triple Package" Explains Why Some Cultural Groups Are More Successful
What you described at the end is exactly sample bias, so I'm confused that you don't consider it so. The claim is roughly that you can look at "successful groups" and determine what makes them culturally superior by assuming their differences account for their success.
Yet if you included a full sample size of that culture from the origin country, the distribution may be (and probably is) no different than a randomly chosen cultural group in the U.S. while still sharing the cultural traits that were assumed to make them superior. Thus an incorrect correlation has been made from a biased sample.
Who Makes the Best Hard Disk Drives?
If they are fairly fault tolerant, a reasonable Seagate discount percentage would overcome that higher failure rate, even allowing for installation costs. They can spread that failure out. An individual cannot, therefore I appreciate that they released the statistics.
Why We Think There's a Multiverse, Not Just Our Universe
I disagree that he's only defined causally disconnected regions; this story actually has a definition of multiverse beyond regions outside of our lightcone. Note one of his later images: a single level 1 universe contained multiple regions which are not causally connected yet are part of the same clump that moved from the false vacuum to dumping energy into matter and radiation.
Any grouping like that is fundamentally isolated because the boundary region that remains in the false vacuum continues to exponentially expand, quickly isolating the clump. Even if the clump itself triggers a conversion of the false vacuum around it, it sounds like the isolation proceeds so much faster that it will be forever isolated by expanding false vacuum regions. With time, we could reach places that are not currently causally connected. It doesn't sound like we could overcome this expansion so easily.
Metal-Free 'Rhubarb' Battery Could Store Renewable Grid Energy
I think the reality is that "renewable" is a code word for many things to many people. To some it means local, to others it just means creating an economic incentive for cleaner power *somewhere*, as the credit system would.
For instance, I wouldn't support the allowance for hydroelectric power most of the time because of the tendency to screw up ecosystems more than some solar panels will, but it's still renewable.
Oil Train Explosion Triggers Evacuation In North Dakota
That's not true at all. If you are considering *passenger* rail, then yes, it's terrible. But we don't really use much passenger rail. That chicken and egg problem aside, US freight rail is pretty good.
For instance: http://www.economist.com/news/business/21576136-quiet-success-americas-freight-railways-back-track
"Even the American Society of Civil Engineers, which howls incessantly (and predictably) about the awful state of the nation’s infrastructure, shows grudging respect for goods railways in a recent report."
Oil Train Explosion Triggers Evacuation In North Dakota
Given your experience, I actually had a question about the pipelines. It would seem most of the failures are caused by a combination of pressure and time. Assuming that you have to operate on a sliding scale of perfect safety for infinite cost and reasonable safety for much lower cost*, is there a way to build pipelines with specific failure points such that you avoid failures at costly points? Something like a fuse in an electrical circuit; you certainly don't want it to blow, but it's there to blow so that worse places don't burn. I've always been a little surprised that discussion of running pipeline through sensitive areas didn't involve a compromise where you just build in a costly but agreed upon sigma of reliability into the region at issue by shunting the risk to an area you're prepared to clean up.
