...but how is this any different from a gene that's turned on or off?
From the article: A mutated gene can be put right by various mechanisms that are already known, but all require a correct copy of the gene to be available to serve as the template. The Purdue team scanned the DNA of the entire arabidopsis genome for a second, cryptic copy of the hothead gene but could find none.
They then go on to say they suspect RNA of holding the backup copy somehow. But (as the article mentions) RNA is unstable and unsuitable for holding data for any decent amount of time. IANAB (I will be one soon), but I suspect there is something they overlooked. For instance, when they 'scanned the genome', they probably scanned the online version (database). If they sequenced the genome of their particular plant, they'll find a backup copy.
Are you seriously saying that the truth of statements you make is not a valid defense to libel in parts of Australia?
Correct. In those states, a statement has to be true AND in the public's interest for it not to be considered libel.
So, you aren't allowed to put flyers up saying that so-and-so is a Nazi war criminal - even if it's true, it hurts him more than it benefits the public to know it.
Instead of NASA investing in one complex, expensive, reliable probe, what if they invested in a method of producing many smaller, less reliable probes? They could send six, or fifteen, or a hundred, depending on launch costs.
The cost of each probe would be cheaper because of (a) economies of scale (mass production), and (b) redundancy means they can use cheaper, less reliable parts.
You're right. I don't know why they bother coming up with an acronym - what's wrong with simply "Messenger"? The earlier probes (Galileo, Voyager, Mariner etc) didn't need a fancy acronym. I guess there's some beaurocratic reason...
Even so, $100k goes a LONG way in a country like Nigeria. You can't really criticise Rolex for that. Sure, someone in a developed country might have come up with something more innovative, but they probably don't need the money as much as this guy would.
I wonder how much $100,000 is compared to the money the Nigerian 412-scammers make...
I thought that logo looked similar. There was a company called Hop-On in Australia a few years ago that supposedly was going to offer free internet access (offset by advertising). The company disappeared before it started connecting users, AFAIK.
The website (www.hopon.com.au) is dead but the internet archive has a copy. That's obviously the same logo.
Firstly, the molecular weight of oxygen is 16, and hydrogen is 1. So water has a weight of 18 grams per mol.
Lets assume for simplicity that air is all nitrogen, N2, molar mass 38 (2*14). So, in terms of molar mass, water is lighter than air. But air is a gas, so 1 mol takes up ~22 litres (at the temperatures of the upper atmosphere) whereas liquid water is 55 mol/litre.
So liquid water is 1,210x more dense than gaseous N2.
Even though in clouds the water is in tiny droplets, it would still be far more dense than air, and is only held up in the sky by warm updrafts.
All you're doing really is relocating the pollution elsewhere or changing the form of the pollution.
True, but in the end it works out more efficient: because a large power plant is designed solely to produce power, it is much more efficient and cleaner at doing it than a small combustion engine is, even taking power transport into consideration.
We don't all have diesel generators in our back sheds to power our homes, because it is cheaper and cleaner to have a high-effeciency power plant supplying millions of homes.

Try NASA's WorldWind.
I can see the pyramids quite clearly with it, and the interface is more fun to use than Google Maps.

This addon is quite cool. It lets you copy files between two Super Shuffles. I've not seen this for iPod shuffle, has anyone else?

There may be something to this idea...

did you know that "gullible" isn't in the dictionary?
Really? wow!
Oh, wait...
