Actually, I think it would be cheaper than going all the way to the moon despite needing the same high exit velocity.
A moon-orbit shot would require the supply ship to carry its own moon-orbit-insertion deceleration reaction mass at take-off, whereas no such thing is required when we're "handing over the hamburger on the highway" both going in the same direction at the same speed.
Which, incidentally, is not such a big deal as you're making it out to be - they do technically similar problematic rendez-vous in orbit all the time, albeit at lower speed.
The great thing about not carrying deceleration reaction mass all the way up is that the same amount of propulsion gets you much more load capacity as all fuel/extra-stage engines you don't take along can be replaced by useful cargo mass. Or you need _exponentially_ less takeoff fuel if you simply take up the same cargo mass, and leave the deceleration mass/engine stage out.
Nope. You're right in saying that the title is wrong - no building cells from scratch here - but the article describes printing growth factor (differentiation factor proteins, in fact) on monolayers of stem cells. The idea here is to force the cells to differentiate into different cell types within the same culture dish, which would be required for building complex tissues from stem cells.
Research materials supplier Bio-Rad has had a "Gene Gun" using this method for eons. While not intended for clinical use like the sleek PowderJect device, at least it looks SciFi-ish cool (see http://www.biorad.com/images/gene_gun1.jpg).
As has been pointed out by many others here already, the PowderJect device is hardly new as well.
NO it's not fake. Really. I thought it was a really really early April Fool's joke so:
1. I opened http://money.cnn.com/2003/05/13/news/economy/twent y/ (thanks Google) and saved the front and back of the new 2004 20$ bank notes to my local HDD
2. Started up Photoshop CS
3. Went and had coffee while it started
4. Had another
5. Tried to open the saved image, and got the error, as advertised.
Big Brother may be 20 years late, but he's here at last. I'm only left wondering if the next version of Photoshop will use my broadband connection to "phone home" to Adobe and the Feds to alert them of my special hobby printing project if I pull this stunt more than once...
Surely the exact progression of cell division in the womb must be fairly chaotic.
Embryonic development is not chaotic; it's a cat, not a cancer. In fact, for a small animal such as C. elegans, the history is every single cell in the animal is known. This is not so for larger animals for practical reasons (ie. size, lack of transparancy, growing in womb etc), but that doesn't imply chaos.
Please do tell us how re-installs in Windows are going to help us get replacements for hardware that's broken on delivery. Especially when the "support line" you're supposed to call is so overburdened I can't get past the busy signal for weeks on end,, and the company in question won't accept e-mail troubleshooting.
I do helpdesk/network support for a small workgroup, and have been exposed to many supplier's idea of "support", mostly regarding hardware failure within warranty period. Apple, IBM and HP have been absolutely great so far.
I recently bought a Canon scanner, which didn't work out of the box (scanhead's jammed). E-mail support acknowledged straight away that I had done all that's humanly possible to get it to work software-wise, and referred me to phone support line to get an exchange. We're now more than three (3) weeks further down the road, and I still haven't been able to get anyone on the line: perpetual busy signal. I did manage to get through in the weekend once, calling from home, but the support person insisted the e-mail support isn't authorised to make exchanges, and wanted to talk me through troubleshooting the scanner - which I didn't have at home of course, knowing there's no point in re-installing the drivers/what have you not they make newbies go through before admitting it's really their hardware that's the problem.
My conclusion: there's still some companies providing decent support. But buying Canon? Never again.

A/. reader with a enough critical sense to get the joke... amazing! Congratulations! Now there's two of us, plus of course the guy seeing his server load go ballistic, who are laughing.
finally someone on Slashdot who's not a Linux zealot, just may be older than 16 and has a clue about what matters to a business versus hobbyists with too much time on their hands.
Finally someone with sense. Of course Jobs won't go near PC's. Too much hardware to support. And most importantly: too dangerous to piss off Gates. Microsoft software and money is what keeps Apple alive. Also, Apple makes it's money selling hardware, not software. (How many Mac people you know are using Claris instead of MS Office??) Switching Apple Inc. into a software-income based business is like starting a new proprietary OS/PC hardware company, like Be did (and BeOS = business disaster. No income. No users. No prospects beyond future hardware no one knows is going to buy, but this is clearly beyond the topic here) Why don't more of you Linux groupies stop ranting about your wishful thinking and think economics for a minute?
BRAVO! Finally a Slashdotter with enough common sense to get it. Apple is a *hardware* company that makes software to sell the boxes. They just have to ask accounting: the money is made shipping boxes, not software. Jobs knows this - hell, everyone should know this by now. By confronting Microsoft with an alternative OS Bill Gates might withdraw Office from the Mac; that would leave the Cupertino gang only the graphical design sector to sell to again. And who knows what they will do once Adobe gets their tools running at serious speed on 64bit Intel CPU's.
"Linux needs more device drivers". "Linux needs to have better autodetect and configuration tools". All you guys are right right, but you're forgetting that, at least from the users' viewpoint there's only a single Windows. They look alike and can be relied on to work somewhat similarly as long as you're not a system administrator (yeah right Mr. Cynic: blue screen all the way). This is what makes it attractive. With Linux there's too many disparate distro's out there to make newbies (and IT managers) feel comfy. RedHat is becoming a de facto standard to some, and to some extent I hope they will. But even RH includes two KDE and Gnome. NOT good! In order to achieve corporate and non-techie desktop "world domination" two distro's would be the max: one resource-friendly highly configurable and open web/mail/file etc. server edition, and one feature-rich, multimedia and overly helpful (=non-configurable, black-box type) desktop edition.
A clone is a genetically perfect duplicate of the original - no more, no less. How can we be clones from aliens if we're all genetically diverse (excluding identical twins)? And if we're allowed to breed freely nowadays (as opposed to the ancient true alien clones), why would aliens have cloned us from them in the first place? Might as well have dumped a few kids of their own here, since the next generation wouldn't have been identical any more. Conclusion: these Raelians are clueless about their 'science', or their aliens were too dumb for us to bother about. IMHO this is Yet Another Dumb New Age Rip-Off Scheme(TM).
Can't we just stick to the point here, please? This man, with or without academic title, obviously has no clue what he's talking about. Yes, there's evolution. No, molecular biology in no way implies everything 'is too complex' to have evolved step-by-step. No, nobody has ever convincingly showed quantummechanics to have ANY influence on DNA, neurons,... (fill in your favorite). This is just one more of those (pseudo-)scientist types hoping to make a fast buck off New Age/Sci Fi afficionados.

Still, I wouldn't mind learning what your comment has to do with DIY style FC?
Byte me, you commie scum!

BRAVO! Finally someone else who actually READS the article. Come on people: it's barely longer than the /. posting itself.
I know reading is no longer fashionable, but this is really pushing it.

Menlo Park, Palo Alto and Stanford remain unaffected as yet. Nothing the matter as far as I can tell. Vaporware news.

Please keep the source code small on these decoders people; the court might wants to save on paper when printing it as "exhibit A" for our attention.
