... when a gene called smedwi-2 is silenced in the adult stem cells of planarians...
That doesn't mean the gene has anything to do with it's regeneration.
If you silenced a gene in me that allowed me to produce red blood cells would you then say you had found the gene responsible for me being able to respirate (live)?
A common problem in trying to count the number of servers running an OS is defining what a 'server' is. Most Linux servers I've seen run ten times the number of virtualhosts that Windows servers do. Do you count a Linux server running 1000 sites as 1 server or 1000?
I wouldn't be surprised if there were more physical servers running Windows, but if you count virtualhosts instead there would be far more sites using Linux.
Yes the problems in the browser need to be fixed.
This might not be a "solution" but until they fix it I think people should know about it. SessionSaver wasn't created for this purpose (it's actually a very useful extension, and despite what you say it still great).
Almost all of the crashes or memory leaks I've had in Firefox are related to third party proprietry extensions that Mozilla has no say over. Sure it shouldn't be able to crash the browser but they can't be stopped from leaking memory. If the Flash plugin gets memory from the system, it's up to Flash to give it back. The plugins for IE (and IE based browsers) are far more mature and have fewer bugs.
Get SessionSaver.
It will restore your open tabs on startup or after a crash. It is also great for when one of the plugins (flash, java, or maybe just Firefox itself) makes the browser slow down over time; after a lot of usage you can just close it and reopen Firefox -- with all your tabs but a fresh start on memory usage. This extension has almost entirely eliminated the need for bookmarks for me too.

Faster DNA Testing

Normal hairs you shed off don't contain a usable DNA tag; contrary to what most believe.
Not always (unless a root is intact), but Mitochondrial DNA can still usually be found. mDNA, while more expensive to test and not as conclusive, is still useful and I think it's been used in some high profile murder cases.
It's a huge jump to say that a single-celled fungi's life can be improved to saying it can also be done for a mammal with thousands of different kinds of cells and billions of cells in total. A lot of our physiology actually relies on cells having a short lifetime. I doubt those mice will even live one day.
Windows programs generally have no dependancies, so a project like this is not really needed. It has been tried before, and there are various projects still taking a stab at this, but I don't think they'll get anywhere.
I think you have misunderstood the way this works.
The arguments passed to this program are the initialization vectors for the algorithm, not a hash to generate collisions for.
No. This only helps you find collisions in two randomly generated strings.
It is still very difficult to produce a colliding file given a pre-existing file on the network.
It should also be noted that edonkey splits a file into 9500KB chunks, and then into smaller chunks again, and hashes each one. It would be far more difficult to produce a chunk that causes collisions on all three levels.
Anyway, I expect an eMule extension will come out soon to allow for sharing of SHA1 hashes between clients (if it doesn't already exist).
Just because collisions can be generated doesn't mean that MD5 is dead.
It might only take minutes to calculate two random strings with the same hash, but it would still take a very long time to calculate a second string that collides with a pre-existing string. So even though it is now cryptographically weak, it can still be used effectively to check the integrity of files.
Just because Steve Jobs is offering OS X for free now, doesn't mean that these people will get OS X for freeif they one day decide to buy a new computer or upgrade. If people in these countries become dependant on an OS that costs money and particularly hardware that they can't manufacture themselves (Apple hardware), they will be at the mercy of multinational corporations and US export taxes etc.

Maybe I've missed something big, but I didn't know such amazing vocal support was built into MIDI formats. I guess I could always put the lyrics in and let Microsoft Sam (tm) sing it for me, but I'd rather die a horrible, horrible death.
Since each device is in parallel, the amount of current each one draws is dependant on it's resistance, ie, it would only draw as much current as needed. There is no reason this wouldn't work.
I thinks it's a really good idea.
If there were several pins, many different voltages would be possible, and a device could even use more than one voltage from one plug (eg, it could draw 2V for a relay, 4V for a power indicator, and the standard AC for the actual thing it's powering.)
By not having to have transformers and big resistors inside all the household devices, there would be huge savings in power, things wouldn't get so hot, wouldn't need such big heatsinks, there would be far less electromagnetic radiation around the place (which is probably responsible for a lot of people getting sick etc), and it's safer too (devices that only need a small DC power source won't electrocute you when you drop them in some water.)
I think that if AJAX picks up and starts to be used everywhere, we should standardize a system so that optionaly, a web browser can inform the server that it has the option to connect to it using an open port on that system. It would really help things if the browser didn't need to connect to the server every few minutes to check for new data. That way, instead of my browser connecting to Gmail's servers every 60 seconds to check for new mail, Gmail's servers can connect to my browser and tell me only when I have new email. This saves processing and bandwidth and increases usability.
This turns AJAX into more of an actual internet protocol, and I think it would really improve things.
To give you an idea, in this scenario, the spacecraft will be able to move the asteroid by a huge 6.35m in 20 years time. I'm sure that a large nuclear power reactor would be able to sustain it's engines (it doesn't have to do much acceleration at all).
If instead of using this totally insane idea of using gravity, which is a very weak force, ten 100 megaton nuclear devices were designed to transfer all of their energy into pushing the asteroid to the side without blowing it to bits (completly theoretical), it would move the asteroid by 192 thousand km in 20 years. That would be more than enough.
When dealing with approximately spherical objects (such as this asteroid), the entire thing can be treated as though it is a point mass in the center (As long as the second mass is not INSIDE the first one, then you get problems). As for the ship, it's too small to matter how it's shaped in this scenario.
For a 20000kg object, and a 9e19kg object (Hygiea), with a distance of 205km between them (1 km away from the asteroid, but the distance between is the centre of masses is much greater, Hygiea has a radius of 204km), the force is 2870N. In comparison, the force of gravity from the Earth will be that much 3.53e12 km away (471 times the distance of Pluto from the Sun at it's farthest point in orbit). It's just more than the gravitational force of four 70kg people standing on the ground. In other words, if a big asteroid comes at us, we are royally boned.

It's a query language.
Yeah. The SQL query language.

More importantly, hopefully this data will bring us one step closer to habitating Earth effectively.

I will simply not download that podcast. I have better things to do with my time than listen to DRM'd podcasts, and I'll let the podcaster know that.

Actually the force is much less than that.
