Free space communications also have the advantage of a group velocity of c, rather than c / 1.5. This may not seem like much a difference, but it's enough that there is a considerable amount of research going into air-core fiber (although air-core is also promising for high power due to lower non-linearity).
Thermometers. They don't make them out of Mercury any more, due to toxicity. Most analog thermometers are now alcohol based, but Gallium is used in quite a few.
I won't even bother listing all the uses for pumps and pressure gauges. This article is clearly trolling.
Ultimately, Earth is a dead end. There will very likely be another extension level event before the sun engulfs the Earth. If we want to survive either, we need to colonize other planets. It may turn out to be infeasible, but it's certainly not impossible.
There's an argument to be made there, but in order to make that system (a welfare state) work in the long term you need to strictly control population growth in the welfare class, and maintain a productive middle class. High technology doesn't maintain itself.
Of course this is ignoring limited resources which demand eventual improvements in technology, or a decrease in population.
Statistical analysis of software failure is valid and necessary when there are inputs with random variation, as in this case. Accomidating for variance in SW isn't all that different from adding tolerances to HW. Thus, we could reasonably expect the same sorts of analysis techniques to be useful.
Violence against one another is about the only threat to our future, we have technology of such a state that we are otherwise pretty well situated for centuries of continued growth.
Continued growth at the current rate is not possible with any energy source for more than about 2 centuries. In 275 years, we would have to collect 20% of all the sunlight falling on earth. If we used local fusion reactors, we would very rapidly heat the earth beyond habitability. If we want to survive as a species, we'll have to transition to a steady state society in relatively short order.
What was the detector? 24 wafers isn't as absured as it may sound, for a one off prototype. Developeding a high yield process takes a lot of time and money, especially if it's a relatively new material system.
Yes, water shields alpha, beta, and gamma radiation. That's why radioactive waste is stored in water.
Fusion is not fission. One results in helium and some neutrons, a tiny fraction of which will be captured by the containment vessel. The other results in the generation of tons of radioactive waste every year. Although, even fission reactors could be made to be far more safe and to generate far less waste, using Gen 3 and Gen 4 designs.
There's likely more radioactive carbon released by the burning of coal than radioactive waste that would be generated by the equivalent fusion power source (if and when fusion becomes economically viable).
Or you could publish the method/algorithm in a journal. Nothing already published qualifies for a patent. Having your name on (high quality) journal articles also can't hurt your job prospects.
First, this really is one of the most promising qubits, although possibly not using this material system. Their resilience to first-order scattering processes has the potential to make them far more to robust to decoherence. Second, true quantum computing (as apposed to quantum cryptography) is unlikely to ever work at room temperature. That does not, however, imply it won't be an important tool for research. Super computers already require large buildings to house them. A quantum super computer would be far more efficient as certain tasks.
As far as the summary/article goes, this journalist is clearly confused. This isn't a fundamental particle, its a "quasi-particle", which is a fancy word for an ensemble property. Phonons, for example, are a quasi-particle used to model quantization of crystal lattice vibrations.
It is difficult to imagine how graphene could replace silicon CMOS when the best lab MOSFETs can't even compete with mass produced Si MOSFETs. High mobility doesn't matter when the off-state leakage current is a couple orders of magnitude higher than in Si. There are interesting theoretical proposals for bi-layer graphene switches which could compete (e.g. BiSFET), but no experimental demonstration that I'm aware of.
Graphene exhibits very high thermal conductivity in plane, but that doesn't help much with getting heat out of a chip, into a heat-sink and then into the air.
Graphene as a switch makes very little since (the lack of a bandgap leads to high leakage/poor modulation depth), but there is a chance it will replace or augment metallization in silicon chips. The push to smaller metallization lines has caused several reliability issues which are still not completely solved. Graphene has shown some promise in this area.
Oculus's software uses a ball-stick model of the head, so that turning also produces a translation. Don't knock it till you've tried it (I'm assuming here you haven't tried it), they've almost completely solved the nausea problem, even for sensitive people.
How could this be used to remotely exploit a CGI-running Apache server? The exploiter would have to have access to the command line or write access to a CGI script, and then why use the exploit in the first place?
Don't confuse the more ancient tribal and pagan customs and beliefs of the people in the region with islam. The former is often falsely attributed to islam. Islam, like christianity, did not completely displace nor eradicate some of the old tribal/pagan stuff. Some, but not all, of the crazier stuff comes from the tribal/pagan days.
This seems a bit like a No True Scotsman fallacy. As far as I understand, ISIS is simply implementing their interpretation of the Koran. If that's not Islam, what is? That interpretation just happens to be atrocious to people and societies that value individual freedom.

Wouldn't that effectively be mob rule?

I think you mean longhorns, not Aggies.
Gallium causes almost all metals to corrode on contact.
Mostly just Aluminum. It also forms room temperature eutectics with other metals, but that's the only commonly used one.
On a related note, it's illegal to bring gallium onto an airplane, due to corrosion concerns.

When you're a politician, everything looks like a tax source.

Just watched it. Very interesting. Thanks for sharing.

Not with an efficiency at or above unity. Hence, no.
Do the math.

Yeah, another good example Bell Labs. What ever came out of there? /sarcasm

Until a blight decimates the monoculture, and we all freeze to death.
Of course we're still discovering it. The problem is that we've been consuming it faster than we're discovering more since the mid 80's.

Just installed homebrew's bash, and it's still showing as vulnerable:
$ /usr/local/bin/bash :;}; echo vulnerable' bash -c "echo this is a test"
$ env x='() {
vulnerable
this is a test
What am I doing wrong?
