There's also a "nature is neutral" law that says any clump of matter has to be neutral. It's just not quite as strict as the colourless law. When you heat up neutral matter enough, all the individual charged particles can go swimming around as if they were free, in a state of matter called a plasma. The plasma as a whole is still neutral though, and the particles aren't really free -- if they try to go too far away they get sucked back, but the plasma behaves as if the individual charged particles were free. A quark-gluon plasma is the same idea, except with colour charged particles roaming around instead of electrically charged ones. The plasma is still colour neutral, but the quarks aren't bound into pairs and triads anymore.
You know, it seems like every single comment I've read has made some allusion to puking, heat, fear of flying or otherwise assuming the transparent plane would be transparent all the time. I realize this place has somehow developed a culture of not reading the article, but did nobody even go see if they had a picture?
Airplane bathrooms strictly limit the size of mile high club members. You have to be small enough to fit two of you with enough room to get their clothes off enough, put all the bits in the right places, and move enough to call it sex.
Which brings up a question... what exactly do the people who require two seats do when they have to go to the bathroom?
The teens I know cam send a lot more than seven an hour and do other things at the same time. It's an average too. Maybe fifty one hour and only a few the next six.
Unless you're using a properly constructed one time pad, which the poster is not, encrypted data is distinguishable from random. The more of it you have, the more distinct it is. With a good encryption algorithm it's not easy, and investigators would probably use other techniques, but it is possible.
The GPS is probably only that expensive because it's a special system. It's not like regular GPS is expensive, and the more sophisticated receivers only cost more because they're not mass produced in the same way.
The did have a real driver run the course first. On the other hand, it's unlikely you'd want the production system to actually RACE.
It doesn't have to be a tree farm, just a managed forest. For example, in my country (Canada) the forested are has increased for at least the last few decades because whenever any forest is cut, more new trees are planted than were taken. I think the situation is similar in most modern foresting countries.
Maybe, but they're probably not getting too far. Humans are a PITA as lab animals. They eat a lot, they're a pain to keep and they take forever to get to reproductive age, or even useful testing age.
"In the context of TFA, a gene that makes mice "dumber" doesn't mean that the gene provides a hidden advantage that has a better tradeoff, and it doesn't mean that being dumb provided a big advantage. All it means is that being dumb wasn't a disadvantage. Or, at least, wasn't a disadvantage strong enough to hurt the mice's reproductive chances."
Since it's a single gene, it's pretty likely that mice without that gene would have arisen at some time. Probably more than once. Assuming we don't usually see mice without the gene, that means that having the gene makes the mice more fit than not having the gene. So it does mean that, probably, having that gene is an advantage over not having it, whether because dumb mice are better than smart ones, or the gene does something else as well.
GP claimed that there are negligible useful materials aside from carbon stored in many plant parts. Whether that's true or not, your reply didn't even address it.
By planting appropriate nitrogen fixing plants you could probably wind up with a net improvement in soil fertility while still removing carbon.
There are lots of ways to avoid releasing methane. You can bury it deep enough, bury it somewhere cold, or create biochar. Probably lots of other ways too.
If you do end up with some methane it's awfully handy for things like heating homes and generating electricity.
I've been telling people for years if they want to help the environment, to stop recycling paper. It makes some people angry. It makes other people think.
I don't know. I bet most people in China and India see themselves as major industrial powers of the world. You've got a good start towards "most people" right there.
Because a wing generates most of it's lift at the front, and most if it's drag at the back, the efficiency of a wing is related to it's aspect ratio, which is the ratio of the wing's length to it's breadth. A high aspect ratio wing is very long and skinny. The ideal wing would be infinitely long, infinitely skinny, and would fly without requiring any energy.
A high efficiency plane needs high efficiency wings. Flying wings are not high aspect ratio. The reason you associate high aspect ratio wings with gliders is that to achieve the best possible glide ratio, gliders have wings with the highest aspect ratio (most efficient) they can achieve with given materials.
A satellite wouldn't get a whole lot more power from the sun than a plane at 60,000 ft. There's not a whole lot of atmosphere to get in the way at that altitude.
Sometimes it is not. Besides the American revolution, it's hard to find examples of violence that actually led to lasting change of the kind desired. The end of slavery (in the US) isn't a good example because slavery was ended legally. The violence was, among other, more important, things, an attempt to reverse that political decision. And it failed.

Let me be more specific - you can also receive and send texts from/to multiple other people at the same time about different topics.
Let's see how many friends you have after you try that one with conference calling.
Perhaps if you didn't sleep ten hours a night....
The teens I know cam send a lot more than seven an hour and do other things at the same time. It's an average too. Maybe fifty one hour and only a few the next six.
You can also receive texts from multiple senders at once. My cousins are rarely testing only one person at a time.

Sure, the article isn't particularly well thought out (it's written by a newspaper production planner), but the concept isn't a bad one.
TFA is almost always full of errors and over simplifications.

Wow. Way to not even read his post.

Sure, NOBODY has thought of that.

It takes more energy to recycle it, apparently.
We probably don't need to consume more of it, but we could certainly stop recycling the huge amounts of paper we currently use.
I suggested not recycling paper on Slashdot before. It really pissed people off. ;)

Propellers are much more efficient than jet engines. And why should a propeller not last five years?

I suppose they might sell some to people who don't want to have a phone AND a tablet, and don't mind walking around with a giant phone.
For everyone else, if you want to type standing up you use your phone. If you want a bigger screen you use your tablet.
Ah, but it's a cell phone, so you'll be able to get it for cheap. With a multi-thousand dollar cell phone contract and locked down, of course.
I suspect newspapers pay more than 30-40% for printing and distribution right now. Possibly a very good deal for them.
