I guess the trick with these will be how to change in from a WORM drive to a write many drive.
These drives still seem Victorian to me (notion stolen from Gibson) and seem prone to mechanical breakage. What's the storage density attainable by other forms of memory systems (What else is there - Bubble memory? What else can we use for storage? - an improved non moving CD-ROM type of gagdet)
Nanotech is cool, but moving parts seem like a dead-end to me....
Hopefully they will avoid the NexGen script flaw of inventing some technology (magic) to save the ship and wrap up the plot in the last 5 minutes. The Original series (TOS) I liked beter because it was more about the people solving the problem instead of the easy way out as previously mentioned. (How much does everyone hate the HoloDeck?!!)
Anyway, what I want to see is more battles - let's face it, watching the enterprise kick butt is alot of fun - TOS vs Klingons, NextGen vs Borg that's what males 12-60 want to see. But please more money on good interesting scripts and less on special effects - Dr. Who stayed around for like 30 years because of that
There has been alot of work using computer genetic algorithyms modeling of diesel engines. Engines with these later designs have 50% reduced emissions and 15% increased fuel efficiency over todays best engines. See

The coral is dead and cleaned up/sterilized...
It, as well as cadaveric(dead people) bone can be commonly used as substitute/filler bone when there are large holes that need to be filled (i.e. traumatic experience).
The coral provides a scaphold for your bodies own osteoclasts and osteoblasts to produce new bone - but it takes a long time to do incorporate - months/years..
I typically avg 90-110and in a crunch time hit 130+ (Yeah that's right 130 hours in a 168 hr week)
I work in a major East cost city - I'm an Orthopaedic Surgery resident.
- crunch time is-
-when a gang war breaks out
-bad weather
-sunny days
-Fri night after the welfare checks get cashed
Sleep is an option.Recognize me by the white plaster in my nails and the black circles under my eyes. I can flash gang signs - strong as a bull and half as smart..
These guys have burned thru 13 million dollars.How will they recoup this loss-charging companies?
How many linux users are there in the USA/worldthat use Ximian/Eazel a million? they'll have to charge some serious moolah to stay solvent..
I think it was Nature's subscription fees (or one of the other "big" journals) that acted as the last straw to break the camels back. Journal fees to libaries are outrageously expensive (thousands$$/year) and to the scientists/engineers several $ hundred/year. This is true in both general science and in medicine (When I finish my residency I can count on paying $250 per year for a monthly must have journal - that's >$20 per issue!)
These journals are usually chock full of advertisements too - which can't be cheap. Publishing costs can't possibly be as high as a regular newstand magazine - scientific journals are udually pretty low demand - lots of text with a few pictures (Black and white usually) or graphs. And they don't pay the authors!!
We bust our balls to write these papers and then get screwed! It's about time that somebody realized that we scientists should ultimately have the power and control over our work.
The journals should be pandering to us - not the other way around. As far as the issue of typos or misquotes - it's alot easier to correct online. Paper journals have to issue an erratum - which subsequent readers might never see.
Greenstick fractures only occur in kids who almost NEVER have a prob healing bone.
This device and other bone stimulators mostly work by increasing cancellous bone mass.
Structurally, bone has basically 2 components. It has a hard, dense outer shell (cortical) and a spongier inside stuffing (cancellous). The bone density devices mostly work on the inside stuffing part (cancellous bone) and not much on the outer shell (cortical)
Shin splints and stress fractures are a cortical problem (outer shell) and don't respond so well to these devices. Rest/activity modification is still the best way to heal these.
Bone deformation induces a pizeoelectric charge on bone (neg on the compressed side I think) and the micro electric environment induces the osteoblasts to lay down more tissue (bone, cart).
Current bone stimulators for people who have trouble healing fractures rely on this principle (pulsed electric fileds or ultrsonic noise).
The frequency selected by the vibrating platform guy was no accident - it's the same one that the pulsed electric field devices work best.
LVAD (Left Ventricular Assist Device) is what he's talking about. They're usually used, as you would guess, on pretty sick people, or during/after a cardiac bypass to help out. It's basically a fancy inflating/deflating balloon in the aorta (main blood veessel coming out of the heart). They make a cool wssst -pssssht noise.
The problem with the artificial hearts was blood clots. This remains to be a problem with any artificial valve used today and so people need to take coumadin (warfarin, aka rat poison) to thin their blood.
Transplants still work the best. I dont think that engineers have come up with any pumps with a MTBF of approx 70 years and 2.7 BILLION cycles.
Mother nature+Evolution = still the best..
YES, and there shouldn't be much to say about it either. Common sense should apply and no arguments
about riduculous extreme situations (reductido ad absurdium).
-US needs oil
-Alaska doesn't supply nearly enough oil to US
-Russia has lots o' oil and no way to ship it
Sooo...
I imagine that they're thinking that they can hook their pieline in our ALREADY BUILT pipeline. Nice neat solution. The USA can slow down drilling in Alaska (environmentalists (me) say Yeah!)
I find it hard to believe that Russia can come up with the capital to finance the project by themselves, since they can't even afford to keep MIR in the sky at a very small fraction of that cost. However, if this is built, this railway line should be immensely profitable! I imagine that Russia will need and seek outside investors to help fund this.
Possible profit scenarios that I can see are:
1 Russia get a new "port" - I imagine that the amount of cargo coming across wil be VAST (spped cost benefits of rail vs shipping)
2 Russia's recently discovered new petroleum fields have had trouble exporting their product. I know that Russia hasn't been able to build their pipeline down to the Mediteranian Sea due to the fighting in the intervening countries. A pipeline thru the tunnel will benefit both Russia and the USA - they have oil, we NEED oil and want to be less dependent on mideast oil.
3 Tourism - drive your own car/RV in RUSSIA!
Technologically this shouldn't be anymore difficult that the Chunnel in terms of digging the tunnel itself, although I imagine that joining the two sides will be a bitch!! (unless they can receive GPS signals underground)
US security protest should be nill - very easy to defend and Rusia can profit if we want to send large amounts of troops thru the tunnel to the mid east areas
I dunno - are there any serious objections to building the tunnel that I haven't though of? - (I imagin that isolationist idiots like Jesse Helms will raise protests.)
If you read the article or looked up Nefopam, then you would know that it has other uses. Most likely someone was using it for some pain study and a few patients said.."Hey, my hiccups stopped" and thus another use was found. ALOT of medicine/science works that way. Not all side effects are bad..
Haldol is supposed to work to a limited extent - I've had 2 patients with intractable hiccups and it kinda worked in 1 guy for a couple of weeks only. It's always dissapointing to try and tell someone that there isn't a drug for something as simple and annoying as hiccups.
Nefopam is related to diphenhydramine (active ingred in Benadryl). It is a CNS analgesic with an unknown mech of analgesic action. It prevents neuronal re-uptake of 5-HT, dopamine and to a lesser extent noradrenaline. It also has anti-cholinergic properties and some sympathomimetic action.
Orthopaedics....we know more than just bones, we just pretend we don't.
usually it's an irritation of your epiglottis or one of the nerves that inervates it.
As far as changing your blood pH by drinking some OJ...won't happen since your blood has a pretty strong buffering system (Bicarb CO2/HCO3- @pH 7.4)
Most sugars (including table sugar) are electrically neutral in solution. They do not change you blood pH except in special cases ( shock).
Nefopam is a central nervous system analgesic with an unknown mechanism of action. It has anti-cholinergic/sympathomimetic actions. It's analgesic properties probably quiet down the irritated nerve that is producing the hiccups.
Well, I am a doctor (Orthopaedic surgery resident). We use quite often a PEMF (pulsed electromagnetic field generator) device to help heal fractures which haven't healed well or are healing too slowly. It seems that the EM field induces an electric charge on the bone. Bone responds to a neg electric field and is induced to grow more bone, thus improving healing times.
Here's a link to EBI medical systems - they're one of the makers of bone stimulators.
An interesting side note - ultrasonic sound has also been used to the same effect. It's proported mechanism is the same as above and possibly that it induces more blood flow into the area which is always beneficial to (bone) healing.
Thus it's not unreasonable that the LEDs might locally increase blood flow and aid in healing.
Photochemistry is still a rather largely unexplored area of chemistry/medicine. The ATP explanation I saw in another post whereby ATPs energy is released by IR light is highly unlikely and doesn't make sense, biochemically speaking, as to why that would help - it's energy has to be directed at a process/reaction.
Anecdotally I do remember that some summer sunlight would always clear up my zits as a teenager - your guess as to the reason is as good as mine.
This is a great idea! Many people have more than a passing interest in science and space - just look at the number of people on Slashdot and SETI@HOME. Projects like these have been done before with large numbers of participants (grade schoolers looking at plant genetics, people identifying and counting birds, etc) and have generally had good, robust results.
Pros 1-large number of interested people - should be easy to get stats on whether everyonne agrees that this is a type A or B crater.
2 the human eye/brain is by far the best pattern recognition tool ever seen - i.e facial differences are relatively minor, yet everyone looks different and is uniquely identifiable.
3 interesting project - inexpensive too!
4 Data is "blinded" to the judges - no one knows where these craters are, thus if alot of people see water effects in many craters in one area a reasonable conjecture can be made.
Cons 1 possible high "noise" level (first post effect) - this can be defeated by introducing a training session which should weed out the first posters
2 possible poor inter-observer correlation -always a more of a problem with complex or more judgemental analysis - I see this in orthopaedics when looking at x-rays of bone fractures. Simpler systems work best!

It would be nice to be able to see these videos.
Anyone know of a way to view Quicktime stuff on Linux??
No, you need oxygen molecules (O2) which there wont be much of down in the hole..In an inert atmosphere you can boil gasoline safely
Looks like you were thinking about Sulphur S, which can form those greenhouse gasses. Sulphur is NOT usually a large component in most rock.
Maybe the explosion of the vaporization will be strong enough to act like a blow gun and just shoot the sand and other debris out.
This isn't going to work in our vast countryside, but maybe in the cities this could be used.
I think the other post explains how potholes aren't caused by plows.
using Mozilla and they look blurry to me. Used Netscape and the evolution was unreadable.
They seem harder on the eyes to read. I'm using a screen resolution of 1024x 768 (or whatever it is).
Not a fan so far - any comments/suggestions to change my mind?

Sorry..
mass and inertia still apply. strap the person to a vibrating heavy platform and they'll still bounce up and down - gravity or no gravity.
sorry, 2 different processes there.
Bone deformation induces a pizeoelectric charge on bone (neg on the compressed side I think) and the micro electric environment induces the osteoblasts to lay down more tissue (bone, cart).
