Is there anything tough enough to sheild against these particle emissions?
And, as a side note, although a Faraday cage wouldn't apply to this case, might it be useful in another?
Bottom line - It's disturbing that they have uncontrolled sources of crazy amount of radweion hanging around like this, be it 3 days or 3 weeks. 3 Weeks just seems ABSURD. You'd think that with the absurd amount of documentation and planning that they have to do to handle potent stuff like this they'd have a plan for anything.
On the other hand, perhaps they got the robot so late because they had to go through 1283091284102934 requisition forms to get it.
First the "Robot Saves Troops" story and now this. Pretty cool how robots are actually helping us nowadays.
"By now, the robot had been in the radiation zone for 90 minutes. The team decided to regroup, but the robot's electronics had failed and it was rooted to the spot. Thankfully, the team had tied a rope around the machine, and it was hauled in, almost knocking over a radiation shield in the process."
This part sounds remarkably familiar...
"On the third day, and after three weeks of continuous warning sirens..."
Whoah. It took them THREE DAYS? I'm glad this wasn't (obviously) a really serious problem. If it were some sort of radiation based bomb, they'd get fried.
From reading these two articles, it seems that if we could somehow shield these robots from outside radiation, these jobs would be done in a flash.
Unfortunately, we need them to recieve radation because if they DON'T, we can't communicate with them.
Now, I'm not a physicist, but might a Faraday Cage (http://en.wikipedia.org/wiki/Faraday_cage) built with an appropriately sized mesh do the job? Just as a microwave lets some radiation out (we can see the burrito cooking inside) while keeping the harmful radiation in (we don't get toasted by the microwaves), couldn't this be used to do the reverse, that is, allow communication in while shielding the robot from radiation?
I realize that these cages must be in a specific shape to work correctly, but if the core components at least, can be shielded, this go a long way towards solving our problems.
Heck, the arms and stuff we can even make (god forbid) mechanical, perhaps in such a way that they won't get owned by the radiation at all.
Or both?
Presumably you already have the song, and downloading it off of the internet would just be like ripping a song off of a CD you already legally own. How is downloading a song that you own through iTunes different from ripping a CD?
Injecting growth factor (PGDF)* laced stuff** into the hearts of mice improves heart function more than just injecting the growth factor or the other stuff alone.
*"[Note: PDGF stands for "Platelet-derived growth factor" and is is one of the numerous proteins that regulate cell growth and division according to Wikipedia.]"
** Self assembling peptide nanofibres - I assume sort've like a bioligically based delivery/binding device for the PGDF, which would explain the synergystic effect.
The title of the article is rather confusing... but here's my take -
First of all, I doubt that this is going to be approved for human use any time soon, even IF they can prove a good success rate.
Speaking of which, what IS their success rate? As promising as this seems, I don't know if I want this if it's a save-you-or-kill-you sort of treatment. However, their study results show that, in mice, it seems to work just fine.
From TFA:
"A blinded and randomized study in 96 rats showed that injecting nanofibers with PDGF-BB, but not nanofibers or PDGF-BB alone, decreased cardiomyocyte death and preserved systolic function after myocardial infarction. A separate blinded and randomized study in 52 rats showed that PDGF-BB delivered with nanofibers decreased infarct size after ischemia/reperfusion."
"[Note: PDGF stands for "Platelet-derived growth factor" and is is one of the numerous proteins that regulate cell growth and division according to Wikipedia.]"
I'm not a doctor/biologist/etc, but is this something we want to be messing with? I mean, sounds like encouraging excessive cell growth in the heart wouldn't be a good idea at all. It's one thing if the patient is dying, but quite another if people are taking this so they're at a lowered risk of a heart attack later. TFA doesn't seem to mention side effects at all, much less potential side effects in humans.
I'm also not a statistician, but their sample size doesn't seem to be all that large, either.
I may be overanalyzing this, but I'll definitely want to see a LOT more research before I'll write this off as anything other than another group of scientists claiming a magic bullet.
If we're broadcasting a signal so strong that some random dude can pick it up at home with homemade equipment, isn't that an unnecessary amount of power being wasted on transmissions?
I don't know about the actual power consumption, but seriously, when your launch costs are in terms of millions (if not billions) of dollars, you shouldn't have this sort of ineffeciency.
Oh, that's what you think. I'm really a super-secret agent with a PhD. in Kicking Your Ass. And a Real doctor.
But uh, yea, I'm a good sheep. The computer I'm posting on is running XPSP2. That should at least buy me some time.
If it were F = MV, then MAYBE, but consider this: Once a bullet is done firing from a gun, it's DONE accelerating towards the target. The only accelleration is going to be in a direction down and against the target. Lighter mass, as you have shown, means more A. So this is bad, not good.
Being a/. reader with your own domain name, you're not the sort of "average customer" either company is trying to cater to... Well, maybe Macs, but definitely not MS.
(Nice site BTW;) )
Sure, but I think that people appreciate (or at least understand) that REAL science is what makes their everyday lives better. They're watching the Science chanel, Discovery, etc, on a television that was produced by real science... and you mentioned the SciFi channel... well that's the Science FICTION channel, and that should tell you something.
And if they DON'T undesrstand how important science is, well, these 'bogus' scientists are simply increasing human appreciation of science, and there's nothing wrong with that. Sure, I'd rather people watch documentaries on string theory or even simple newtonian mechanics, but people don't find that interesting. Whatever gets people interested in science, I suppose, can't be ALL bad.
Furthurmore, I doubt these scientists are going to be doing research at CERN (for example) as an alternative to what they're doing now.
Most of us DON'T use hybrid cars. The overall effeciency gain here would likely be an actual GAIN, instead of a loss. This is key for this idea to even be CONSIDERED.
Of course, then you bring up the (Quite legitimate) debate that, hey, what right does the state have to take my gas anyway?
I'm sure that these gamers' being safer drivers on cell phones will more than make up for the deaths in terms of fewer car crashes AND increased productivity.
Am I not the only one that finds this not only outrageous but terrifying? Not only are two federeal agents coming to the home of someone who simply requested a book (And not even like "Terrorism for Dummies", at that, just a book of quotes), but it's OUR tax money at work sponsoring this.
I wonder where the government reasonably bases this sort of decision on...
I'm sure writing a program to scan through files for a username/password type of entry wouldn't be difficult at all. Most of the important data (Email addresses, usernames, passwords, credit card numbers, etc) are in static format, so they're easy to distinguish from random typing (like this).
Most of the desktops that I know that run Win2k are run by schools, universities, etc. I haven't seen someone's PC running win2k yet. Also, these desktops (the ones run by schools, at the library, etc) are usually either (A) very secure or (B) no one expects them to be secure. So this could be worse, I think.
This could be a major problem if it infected SP2 computers.

Nah, they're just plasma-conduit miners sending odd data to our android.

On one hand, people will think "Gah, I don't want to buy a Mac, they don't have IE!"
But when they actually TRY safari/FF, they'll realize that these browsers are AT LEAST as good as IE, and switch over for sure.
Could go either way.

Read this as "Mafia Lights Explained"?
"Oh shit," I thought, "now that it's been explained to me, they'll come after me next!"
I'm sure we won't be hearing from the OP anymore.
Lights in distance probably headlights from far off cars! Populace of Marfa stunned! Physicists skeptical! Sensastionalists de-sensastionalized!
I've never heard of these "Marfa Lights," but I can't help making fun of them out of context...
