So all the nanofibre is doing is holding the survival signalling molecule (PDGF) in place. Without the the nanofibre the signal gets carried away in the blood. Unfolded nanofibre is mixed with the signalling molecule in the lab. The solution is injected to the "injury" site. The nanofibres change shape when put into a different chemical environment(the animal's body). At the injection site fibres form. Trapped within the fibres is the signalling molecule. The molecule gives survival signals to the target cell continuously without being swept away by the blood. More survival signal equates to...you guessed it' more survival.

My good man. Seems as if you haven't been fortunate enough to come accross one of these. http://www.exceldryer.com/Products/xlerator.asp It says right on the machine "Feel the power!" and it doesn't lie. I'd actually take it over paper towel.
Once they've got the gene(s?) into bacteria making more of the substance becomes very easy. Grow a whole bunch of the transgenic bacteria and extract product. Cost will vary with application. For everyday uses (running shoes) it'd be cheap but for implants into humans it needs to be a lot purer as to not trigger an immune response. Even small bits of leftover bacteria is a very bad thing. Pure typically = $$.
To summarize this link http://volcano.und.edu/vwdocs/Gases/climate.html its the sulphur dioxide reaching the stratosphere that blocks solar radiation. Man released SO2 doesn't typically make it all the way up to the stratosphere.
Unfortunately intentionally cranking this stuff into the upper atmosphere isn't a solution to global warming since SO2 leads to ozone breakdown.
..all they money from lost hours of Slashdoters reading the constant barrage of space elevator "news" went towards building the damn thing. Hell, if we included lost time/$$$ due to dupes we could throw in a Mars colony while we're at it.
From TFA: At first they're not even marketing to average joe. They're going after major consumers like the CN (railway) that spends $11 billion a year on fuel. 10% of 11 billion is a lot.
Presumably if/when this works for the big guys the company will have more money to throw around. Economy of scale will kick in and bring the device to the average consumer at a lower price.
Maybe they're going after that last group of buyers that are still afraid to give out their credit card number out on the internet. Calling someone to give a number seems safer to some, even if the call technically is over the internet. But at least its free. Nobody is going to call long distance to give out a CC number.
Seems like that'd be a good place to test the system out. While talking with extraterestrials would be pretty awesome, having a chat with a dolphin would be pretty cool too. Remember: "The second most intelligent [species] were of course dolphins"
It seems like the major breakthrough is in the tumor's interactions with the cells surrounding it. The math showed that although cells will divide exponentially in the lab, in the body there is competition with other cells. This competition slows the growth of the tumors. The rate at which the tumor actually grows depends on the interactions at the boundary normal and tumorous cells. Some possible influences on the interaction are 1) the ability for the non-tumorous cells to resist the microacidic environment reduce cell death surrounding the tumor. Less dead cells = less space for the tumor to expand into. The note that neutrophils (a type of white blood cell) are resistant to acidic environments. If these cells can be recruited (I think thats what they did) then the tumor can be somewhat encapsulated. 2) the ability of the tumor to break down proteins in the extracellular matrix. This is basically all the junk that helps hold cells together. Digesting these proteins again gives more space for expansion. When normal cells lose some of these bonds they can also become succeptable to removal by the immune system. I suppose there are drugs that target the enzymes that degrade the matrix proteins.
Math shows growth patterns and describes which system(s) are in play and how best to treat.
Well thats my best guess after skimming the paper.
Anybody know why they'd have to specify that as being ok? At one point somebody thought terrorists could smuggle aboard destructicons and then build devastator??
I seem to remember phones having some sort of feature that allowed programming in numbers. They had buttons specifically for each emergency number. They even had pretty pictures on them. Can the police etc no longer be contacted in a non-911 manner?
For anyone concerned with their family's well being surely reading the phone's manual on how to program numbers doesn't seem to be a particularly unreasonable task.
Two days ago something happened that could have caused some major problems. It didn't. Oh and be sure to catch the auroras yesterday. They sure were great. Thanks for the heads up;)
They are very popular articles. Just look how many replies they get. Sometimes they even more than the original article. Not only that but there is an outpouring of emotion. So much anger is spawned from just a few clicks of the keyboard (ok maybe they just copy paste from the original post. I really dunno) Most importantly though it is the one subject that ALL Slashdotters can agree upon. Dupes are TEH Suck.
Just a thought. How about the next obvious dupe that comes along nobody reply. See if we can it to get off the front page without a single reply. It'll never happen but a man can dream.
Slashdot Mirror
That made things a lot clearer.
Who'd of thought your knowledge would pay off so soon?
Ok. So the human genome is ~ 3.2 billion base pairs long.
In helical form every 10 base pairs is 3.32nm long.
so 3.2e9 bp / (10 bp/turn) * 3.32e-9 m = 1.06m
since we have 2 genome copies in us double that number to 2.12m
now there's ~50 TRILLION cells in the human body. This number seemed to vary a lot.
2.12m * 50e12 = 106e12m
=106e9 km
so 106 billion km by my count or approximately 4 light DAYS!
Naw, its because prosecutors get their movies just like everyone else.

None of those people ended up with their lappy because some guy bought them all online while the mob was busy crushing strollers.
Thanks. You just made my day.
Anybody else smell a Mythbusters episode in the works? We all know how well Adam does with vacuums.
Yah that and 53% of all statistics are made up on the spot.

"Developed with the help of the British Aerospace wind tunnel engineers"
If by "developed" they mean they ripped out the wind tunnel fan and called it a day, then yes.
Anybody know why they'd have to specify that as being ok?

This one has a nice map of where auroral activity is taking place and shows relative intensity.

just multiply atoms per second
Forgive me and my lack of physics background but isn't knowing the rate of atoms -> ion + e- the same thing as knowing current?
