However, a pool that is 1.36 square miles, 1 milk-jug deep does actually does put it into perspective quite well, especially compared to the volume of the ocean.

They get clickstream data from the big ISPs. In theory, if the samples are large enough and their models are appropriately calibrated, this ought to be a reasonable way to do it.

This also means that compression for on-line files is enjoying a bit of a renaissance.

I have trouble explaining the difficulty of stuff to myself.

Indeed. Why do people insist on calling things "Genomes" or talking about the "DNA" of concepts that have no relationships with the meanings of such terms?

While this sounds like a fun project, if you want a cheap PCR machine, why not buy a used one for a few hundred bucks? Getting molecular biology to work is going to be hard enough without trying to reinvent the wheel and re-do the relativel

It sounded like the problem affected one 96-well plate. I doubt that it was directly related to the increase in volume. This sort of mix-up can happen very easily - for example, if you load a plate into a machine backwards. They (or rathe

I was about to say that it is very useful material to learn. But looking at the syllabus link, I realized that I took the AB course (long ago), which has apparently been discontinued. The course I took was a pretty solid basic introduct

PEG is the abbreviation for PolyEthylene Glycol. Just a chemical they add that makes the transformation work more efficiently. DNA, as you probably know, is a double-stranded molecule, and the strands have complementary sequences. When th

It's not clear to me whether they are simply banning the insertion of paid tweets via the API, or they're saying that you can't put ads (which are not tweets) in the same area of a UI in which a timeline of tweets is being displayed.

Bacteria will often take up DNA from their environment, and this ability, called "competence" is widely used in molecular biology. In this case, they treated the cells with a chemical called polyethylene glycol, which increases the efficie

The field actually does typically call itself "synthetic biology," rather than "artificial life".

Honestly, what's getting old is a small, vocal, paranoid, patronizing minority blowing things way out of perspective while hundreds of millions of people go about their lives in the same world that not long ago had both water-coolers and te

What ever happened to FOAF? The way to do this is to build it on the web, not to try to create some new peer-to-peer system.

Part of the motivation for putting 'like' buttons all over the web is to gather more granular behavioural data on users, which is eventually going to enable much better targeted ads. They aren't stupid. That said, I'm still mystified by t

I don't doubt it, but $99 << $2000. The technologies are going to continue to improve over the next few years until we all get cheap whole-genome sequencing, so just expect to re-do your analysis a few times as the cost drops and c

You'd have to build it, but how about model rockets?

That photosensitive paper that lets you make 'photographs' of objects (like leaves and rocks) was pretty fun.

This is extremely useful just to be able to see rates across different areas and skillsets.

Unless they start auditing source code and everyone's entire development process, there are lots of ways in which such a rule could be violated that would be completely undetectable (and some cases that would be easily detectable too).

It seems absurd and unenforcable; I mean, applications are originally written in my head.

In principle, couldn't any of these translation layers be converted to code generators that would produce compiled Obj-C that would fall within the rules? Surely they aren't saying that all code has to be entirely hand-written? If so, then
