Doing even the most cursory of searches on gallium and reading through the Wikipedia entry (http://en.wikipedia.org/wiki/Gallium) would suggest that gallium is not chemically intert, may not be non-toxic to humans, and given that extremities can easily get cold enough to drop below the freezing point of gallium, I'd have to say that it might rather well leave a residue, forget about the stickiness others have reported.

Yea, that'd be great: inject liquid metal, have it thicken and solidify in your feet and fingertips because you step outside on a brisk day, giving you the equivalent of massive frostbite. No thank you.

There are growing numbers of Chinese researchers in my field (neuroscience) and their results always need to be taken with an extra-large grain of salt. It looks like the same is true here.

Did anyone read the Wikipedia entry?

"Hemerythrin and myohemerythrin are essentially colorless when deoxygenated, but turn a violet-pink in the oxygenated state."

Since much of our skin tone (for lighter colored skins) comes from blood, this is going to make for some VERY interesting looking people!!!

If time is an emergent phenomenon, then how does the first event happen? If time does not yet exist, then there is no was to distinguish an event. By the parent's suggestion, time can only be propelled forward when already in motion, by the contribution of each new event. The very ideas of "first" and "new" presuppose the existence of time, and thus despite this likely significant scientific work, we continue to have a tautology until an instantiation somehow starts things off.

We are still, also, a long way away from understanding what causes wavefunction collapse, since the notion of observation is clearly ludicrous: there are no observers in the center of the sun, or on the far side of Jupiter, as two minor examples.

Indeed, especially since the skills of programming a mechanical engine go many eons farther back with, I believe, the invention of the loom. The result was somewhat different (a woven pattern, rather than a scalar value), but the idea of a set of sequentially executed instructions with loops, counting variables, and exceptions, started a long time before Babbage. Knitting and crocheting is rather quite similar, and embodies similarily pre-existing art, as well.

Terminology. Seems like the parent poster and a lot of other respondents are picking apart the use of the word "meeting" when used as a synonym for scientific conference. Frankly, I've never seen anyone do that before with such misdirected certainty. The OP clearly shows that this is a scientific meeting ("NASA's Lunar Science Forum became the largest scientific gathering..."). In my neck of the world, we have 35,000 people scientific meetings that are also called conferences and even congresses. The smaller ones are called symposia or workshops. I organize one that meets every two years (we explicitly emphasize the more informal interaction phase of such gatherings, which our participants appreciate greatly). Everyone understands that, in that context, "meeting" is a synonym for "conference".

So why all the nit-picking from conflating a scientific meeting with a business meeting? These two beasts are different kinds of events with different goals, different structure, and different levels of participation.

If you read the article, you'll realize that there is a separate laser accelerator necessary BEFORE this chip, and then a second high-power IR laser necessary to drive the chip.

More-or-less, they've increased the efficiency of laser-based electron acceleration. Good on them, but the solution isn't, as the summary suggests by omission, just a small chip alone and nothing else.

More importantly for the parent (I know, I know, don't feed the trolls), the presented accelerator only accelerates electrons, and is intended as a gamma and x-ray source. That's very different from accelerating electrons and positrons to nearly the speed of light, or protons, or atomic nuclei, etc. To do high-energy physics, you need big, big accelerators. The device to accelerate a single subatomic particle to levels where it carries as much energy as a brick dropped on your foot, isn't going to be a crystal a few millimeters on a side.

I run a scientific research lab in a Big University You Have Heard Of. I had a conversation with an intern and a post-doc earlier this week where we talked about figures that could be added to a review paper the intern is working on. I swear I used the words, "I'll make up a figure ..." to describe the actions of collecting the necessary supporting data to create a figure for the paper that my post-doc suggested would be instructional. "Make up" in this case meant, "construct," and wholly lacked nefarious, subversive, or deceptive connotations.

And I speak English as my mother tongue.

The so-called conspiracy to commit fraud here is a bunch of hooey. The only thing the authors are guilty of is not submitting a fully completed manuscript.

Your order-of-magnitude higher ID than the parent poster suggests an explanation.

Myself, I like Courier. But then, I'm in the lower 10x of that equation.

And please, if you're going to criticize someone's choice of font, take a moment to do it with precision and figure out what the name of the font is.

Given that Orwell got so very much right about the future, why exclude 1984 from the list? Just to make an interesting discussion that would have been largely already well-hashed-out otherwise?

Yeah, they should have implemented a more continuous system such that if, for example, two addresses had no words in common, they'd be quite distant, one word, within a large region, two words, a small region. Then, on top of that, put in alphabetic sorting so that elephant.reciprocity.meander is pretty close to elephant.reciprocity.nominate and really close to elephant.recapitulate.meander.

Double plus good if they had made the three words subject-verb-object sentences (but maybe there aren't enough English words for that).

While the current approach is an unfortunate miss from the human usability aspect, at least they managed to put short descriptors in urban areas, leaving longer ones for the middle of big bodies of water.

Exactly. The outside of a piece of mail is considered public. There is no expectation of privacy. That's, after all, why there is an envelope in the first place! Stuff inside the envelope is considered private, and protected. The outside? No.

Personally, I've long suspected that the Post Office was doing something like this because they've displayed an ability to trace a given piece of mail when requested, despite not having purchased a tracking service, albeit with substantial latency. How can they tell that a bit of mail from my Aunt Mabel did or didn't come through my local post office in the last two weeks without making some kind of record of every piece?

Actually, we hit pretty close to exactly proportional representation: the gender breakdown of our speakers is nearly identical to the gender breakdown of our general attendance (excluding invited speakers). But we have to work super hard to get even that because, as described above, everyone else is also inviting the few qualified female speakers. It would be impossible to get 50/50, as there just aren't enough qualified female researchers in our field.

I run an international conference in a relatively small field, that is, one with only a few thousand researchers all told. We do pretty well at gender balance in our invited speakers, but it is MUCH HARDER to invite qualified female speakers than male ones.

Why?

Because there are fewer of them, so they are in higher demand, since all of the conference organizers want them to speak. Our conference typically has about a 90% acceptance rate for our invitations, for male speakers. For female speakers, it's closer to 50%.

There's a very serious question for privacy/security-minded folks that need to figure out --- What was the encryption used on this hard drive that the police were able to crack it?

Many times I'd like to see my password in clear text (like when entering new passwords, to make sure they're correct). It would be convenient to have some way to temporarily turn off asterisk masking.
