You don't need to heat it up (although it helps). Water ice is an unusual solid in that it turns to a liquid under pressure, this is due to the fact that ice is less dense that liquid water. Therfore once you go deep enough under the surface any water found there must be in either liquid or gaseous form. This puts a physical upper limit on how deep the ice crust can be on Europa, allthough I have no idea what that limit is.
The really intriging thing about Europa's tidal heating is that it is strong enough to induce undersea volcanic plumes, which is where many people think life first arose on Earth.
Yes, and even without those problems you still have to get people to use it. A few years ago the CSIRO here in Oz had a wonderfull idea for purifying water in third world counties, simply mix crushed charcoal and clay and make it into a pot. The pot is pourous so when you put water in it, it seaps through and is collected in a traditional water tight pot below. The invention filters out parasites, solids, and even bacteria.
Someone comes in to the doctor's office overtired...
Yep, that was the only symptom my brother-in-law had, they gave him a general check up and found a large tumour on his prostrate. Luckily they cut it all out but it was a couple of months not knowing whether it had spread or not. His older brother didn't bother going to the doctor and is now terminal with prostrate cancer that has spread thru his body.
What you describe sounds like a money making scam as opposed to preventive medicine. They don't advertise "full body scans" here in Oz, but the UHC system does advertise to get people to go for prostrate checks and other types of simple* screenings, they also send doctors to give free check ups at the workplace because early diagnosis is both cheaper for the health system and less painfull for the patient.
*simple - because a finger up the bum isn't what I would call a "high tech" test.
There's a lot of distortion about oil reserves from the doomer crowd.
Of course there's no distortion from oil companies who's stock price is partially based on the size of the reserves they control. Nor is there any distortion from the Saudi's and other oil producing hell-holes, who's only leverage in international politics is the size of their reserves.
If a very attractive girl decides to strip naked and run around inside a men's prison should the girl not be at least partially responsible for anything that happens to her.
No, a stupid victim is not responsible for the immorality of their attacker. If think what you are trying to say is that Sony failed to apply due dilligence, which AFAIK is yet to be proven.
nothing had HOLES IN IT (or next to it or something), which sounds like a major stretch, but all of the scientific theories of the very early origins of the universe are pretty much of a stretch. It's something that's at least as falsifiable as any theory of the early Big Bang period.
It's a common misconception that the BBT says the universe came from nothing. It doesn't, it claims it came from a singularity. A singularity is not nothing, particularly when it has the entire universe compressed into it. Where the singularity came from is currently not part of the BBT, also the early part of the BBT relates to a time ~10e-37 seconds AFTER the singularity started to expand and is well established science compared to this idea.
When I was a kid I had to wait for the B&W TV to warm up, now I'm an old fart I have to wait just as long for the digital set top box to boot up. Somewhere in between I had a TV that came on instantly.
The reality of the situation is that, with vanishingly few exceptions, a biologist who is determined to do any work which does not presuppose the existence of evolution will quickly find himself an unemployed outcast. Students unwilling to presuppose the existence of evolution will have a very hard time graduating with an advanced degree relevant to the field.
you end up with mulitple stations broadcasting the same show
Yeah, last night the royal wedding was on almost every fucking station. I was going to watch the chaser's "uninformed and unconstitutional" coverage of it but then the royal family pulled the plug on their licence.
When the Boomers start dying off, traditional television as we know it will probably die with them.
I'm a boomer, and judging by your post I care a whole lot less about TV than you do. Same goes for my 77yo dad who spends most days in his garden and most evenings on his computer.
I'm not saying it can't be improved, I'm saying that the headline is bullshit. Science flourished during the last century more than any other time in human history and during that time information was under the same copyright regime and was significantly more difficult to access since it was only available in paper form up until the 1990's. I'm currently not affiliated with a university, but for a few bucks I could get hold of pretty much any paper you cited a lot easier, faster, (and often cheaper), than I could 30yrs ago where my only option would have been; a trip to the newsagent + a full subscription + a snail mail request for the specific back issue + a trip to the post office + a lot of waiting.
Despite the absurdiy of copyright laws, never in the 10,000yr history of civilization has information been more accessible to the masses than it is today. The major problem now is teaching the masses how to reasearch a subject so they can sort the shit from the clay themselves.
Somewhere back in the late 80's the right wing recognised the coal industry were facing extinction and have reacted by conducting a major disinformation campaign to convince their followers to act against their own best interest, it has worked spectacularly well. Somewhat ironically their hero Ronald Reagan was instrumental in creating the internation cap and trade system for sulphur emmission in order to reduce acid rain, that also worked spectaularly well.
What disappoints me is that these are consumption-only devices -- No User-Serviceable Parts Inside. This won't help students learn how computers work or how to write software.
30yrs ago I did all my own mechanical repairs on my car, I now have a vastly more sophisticated car and pay a qualified mechanic to maintain it. The detailed workings of all the different technology in the modern world will simply not fit inside a human brain, a broad knowledge of science, the ability to research a subject, and an expertise in a few specific sub-domains is the best anyone can hope for. In other words the vast majority of students will grow up to be computer users, only a tiny minority will grow up to be electronics engineeers or computer scientists.

If water is ubiquitous
Water is the third most common molecule in the universe.

Yes the BB continues to this day, that's how we know there was a big bang! Also time is relative, there is no universal timer tick.

Most skeptics reject everything outright
Those people are not skeptics.
"Flobbalob" reminds me of "Bill and Ben the flower pot men".

As a chemist, I often have to fight the urge to punch somebody in the face when they say "dihydrogen monoxide" or similar nonsense names for water.
Humourless and violent - nice combo.

Hardly. This practice is a minor parasite riding on the back of Science, it's been there for at least 100yrs.
Too many particles with no explanation why they should have this mass or spin, or whatever. No predictions, just observations.
You cannot explain the fundemental building blocks of the universe, if you could then they wouldn't be the fundemental building blocks. Also if the Higgs is not a prediction, then what is it?
I find it rather odd that Americans pay significantly less tax than most westerner's and spend significantly more time time complaining about it.
No. Yes (provided you are only interested in Americans). Don't know.
