Eh, not so much generation as different way people think. I'm not old, have multiple laptops, desktops and smart phones. More often than not, when I need to seriously think about a paper I print it out and annotate the margins, under

A minor note: the LightSail team says the perigee is lowering due to atmospheric drag not due to the sun slowing it down: > The perigee, or low point of its orbit, has dropped by a similar amount, which is consistent with pre-flight ex

I left a reply on the OP (before seeing this), which links to NIH, CDC and a review of the subject: https://news.ycombinator.com/item?id=20511244 It's not that the symptoms don't exist. It's that the symptom

"Chronic Lyme" is notoriously difficult to diagnose because there is very little evidence that it is a real illness. While there is some research on the subject, the medical community still widely believes that chronic lyme is No

Because enough people will believe it when they see an asteroid looming towards them on CNN, Fox, whatever. There are plenty of people that deny climate change because it's convenient, either politically or economically. There are co

There is a real difference between a singular event like an asteroid, and a slowly boiling frog like climate change. You can point at an asteroid and say "That thing. It's going to melt half the planet." I'd like to th

It's especially tragic because any attempt to fix the situation implicitly crushes nations that are presently bootstrapping themselves into industrialization. E.g. major "developed" countries got a free ride on cheap, dirty

Mars is a radically different planet and has its own climate. It doesn't have anything to do with the sun getting warmer though, e.g. we can't blame the sun for the Earth warming up just because Mars is also warming up. A few of

Except that, from the article, the only way to really use IPFS for pretty names is to use DNSlink and not IPNS. Because IPNS is unusably slow. So IPFS might not theoretically rely on DNS, but it seems that it does practically rely on DNS i

Yeah, folks, don't do this. Some drugs are relatively benign to quit cold turkey (a sizable percentage of people may run into irritating side effects like nausea, etc) but it won't kill you. Other drugs like benzos can be fatal to

I don't think this is fair for several reasons. First, cancer treatment drugs are tested heavily in-vitro first, where the only significant metric is reduction of tumor mass. Clinical trials for cancer treatments are different from o

Frankly, a lot of this is the patient's fault too. The vast majority of people _do not_ want to change their lifestyle. They don't want to quit smoking, drinking, eating fried food and leading a sedentary life. They don't

Not quite the same as pure vertical farming, but greenhouse + aquaponics + high levels of automation seems to work well for certain varieties of vegetables that naturally vine. E.g. like the Houwelings tomato farm: http://www.ho

While that's true, the OP's solution is one way to help promote thicker stems if your lighting is sub-par. E.g. more light is best, but failing that for some reason (budget, space, whatever), stimulating the stems is a reasonable

FWIW, CRISPR isn't a great analogy. It's a well understood mechanism, and not really all that different from standard genome editing techniques like restriction enzymes, zinc-finger nucleases, etc. It's new and flashy and s

This gets thrown around a lot, but has two major problems. First, it's unlikely that comparable funding will also be transferred from NASA to NOAA. E.g. NASA will be told to stop earth science research and have it's budget cut a
