Simply engineer a heat shield for the warhead that is ablative and outgasses enough to provide a protective layer around the object. The advantage of this over a mirror is that the laser's heat is carried away by the emitted gas.
For countries with MIVR'ed ICBM's, the dummy vehicles can be replaced with some sort of defensive weapon. In the case of Russia, you could have two warheads with four defensive vehicles per warhead on each ICBM, or the US could have 3 warheads with 3 defensive vehicles each per ICBM. Since they can be independently targeted, the defensive vehicles could arrive ahead of the warhead between the line of site of the laser and the trajectory of the active warhead. A nice thick cloud of opaque smoke could do the trick. And be cheaper than reflective/ablative armor.
This headline is misleading. We don't yet know what caused the crash, so it's a leap to say PTC could have prevented it.
From one of the articles I read a few days ago, it wouldn't have mattered if the system was in place and turned on. According to the article the train involved in the crash was an older one that wasn't compatible with that system. I don't know if that's true, or not, but if so, the headline is very misleading.
Cats kill at least an order of magnitude more birds than windmills do.
Yes, but the majority of those cats eat the birds. I haven't seen a windmill that can do that.
Perhaps we should start a new market by composting the bird carcasses and selling the fertilizer to farmers. I wonder if windmill ground bird compost will be acceptable for organic farms. If so, it sounds like a win-win.
What makes you think that the autonomous truck will hit the car just like a manned truck? I'd think that with the sensors on the truck tied directly into the autonomous control systems the autotruck could react thousands of times faster and more effectively than a human being truck driver.
It may be able to react much faster, but due to inertia, the stopping distance for something as heavy as a loaded truck is considerably longer than that of a car. And when a car suddenly swerves in front of the truck and immediately brakes, a slightly improved reaction time is only going to help so much. A train is an even more extreme case. Those can take miles to come to a stop do to all of the inertia.
There is no consistent approach and due to various changes, even the historical usage varies considerably
No kidding. My Corvette is usually only manned by me, and occasionally one other person. It has no armament, and scares the hell out of me when it gets off the ground, let alone leaves the atmosphere. And it might as well be parked, even at top speed, when compared to the slowest space faring vehicles.
Yeah, you best hope a stent doesn't cause a clot either, or you don't react poorly to the clot medication, or get yourself hurt while on it...
Restenosis is going to occur with any stent. The endothelial cells that keep plaque from accumulating are long gone by the time we can detect the issue. Until a vessel is 90% stenotic, it will effectively flow the same. You can postpone restenosis with drug eluting stents, which have been in use for a long time now. The elution distance is not very far, so this type of treatment does not cause systemic issues with blood not clotting like taking oral medications.
If the electronics in this stent can give flow information, then it also has the advantage of the patient not needing to go back into the Cath lab to have a catheter fished through their femoral artery to verify it. Which carries it's own set of risks. In the last few years, it has become possible to use CT to check this, but there is the radiation exposure, and a margin for error involved with that. Plus I don't know if that's become something insurance will pay for.
Considering bio-soluble stents have been around for several years, I don't think the stent structure itself is going to be a problem. The electronics, I wouldn't know. I didn't RTFA, but perhaps they remain lodged in the plaque that caused the stenosis to begin with. As far as causing another blockage, it has been well known for some time that restenosis will occur in a standard stent. Once endothelial function becomes impaired, plaque will accumulate. Drug eluting stents can postpone this, but there is no way to avoid it permanently.

Get the cyborg cockroaches to scavenge for parts and start converting other cockroaches into cyborgs too. Once you have enough, you demand "One Billion Dollars" from the governments of the world, or risk being invaded by terminator roaches.
The government argued that a laptop was simply a "container,"
They x-rayed it and it obviously wasn't full of explosives and it's not a liquid container of 3 ounces (or less) in a "one quart sized, clear plastic bag".
If they can prove that the files on the computer can somehow explode and be an imminent threat to the flight he was on, I might agree with the TSA. Otherwise I hope this judges decision is upheld. It would be a nice baby step toward having our constitutional rights restored.
By now all of the air would have leaked out of the tires.
Done be silly. In the neighborhood they parked it, it's probably sitting on blocks because someone stole the rims. Just think how cool those 32's look on a BMW 325.
Ive dated a lot of women who it turns out are looking for the "cowboy" type or the "biker" type or the "go chiefs" type. And are unhappy with me because i havent subscribed to any of these store-bought personality templates.
I prefer to just be who i am. A multifaceted individual with a wide variety of interests and hobbies.
Women HATE that.
Here's the thing. Women are just as screwed up as men. However, in a slightly different way.
Most women are initially attracted to 'the "cowboy" type or the "biker" type or the "go chiefs" type'. Though I'm not sure if it's an inherent thing, or learned. But they almost never want you to actually be that way long term. They want to turn you into that "multifaceted individual", not actually be that way from the start.
Don't get me wrong, as men, we're just as screwed up as to what we're attracted to and what we want too.
I don't take much stock in this story due to such a small sample size, limited history, and that the numbers over the history of it don't even show a trend at this point.
Still, the "mystery" of IT has been diminishing for years as most people are at least familiar with computers now. The days of the BOFH are more or less over. So most people have a hard time accepting "I can't do what you want because digital Zeus says it can't be done". Everyone needs their own phone, OS, program, or whatever.
The younger generations are also always lazier than the older ones. It was true when the baby-boomers were young, then gen-x, and now millenilals. In some ways it's true. It takes a few years to develop a good work ethic. But it's often that the newest generation just has a different way of doing things because they view the world differently.
I got my wife a Roomba vacuum robot 6 or 7 years ago. She admitted to me that at first she thought it was a waste of money. But after using it for a day or two, she changed her mind completely. We set it up to clean the first floor of our house at night. We just got a Neato BotVac series one this week. It's a big improvement over the older Roomba.We still run the upright vacuum cleaner every couple of weeks. But in a house with three large dogs, it would be a daily chore w/o the robot vacuums. It's not Rosie the robot, but they are a time saver for us.
I think my daughter was a little disappointed. She was expecting to be able to have a conversation with the Roomba one. Or at least R2D2 level of responses.
Like I said, it may never happen. But if it comes to pass that rotten dinosaurs are no longer a viable option, we may launch big fucking computer tracked magnifying glasses into orbit to focus enough energy to make it possible. Or use orbital solar powered lasers, or microwave transmission. We could do the same from the ground, it's probably less likely to cook the general population if it's coming from the ground.
Powered flight in heavier than air craft wasn't possible 150 years ago. Just look at all of the advances there have been in that time. Who knows what the next 150 years will bring.
And that's why I finished my post with the following: "It's probably not a practical solution currently. But as efficiencies increase, it's at least feasible it may be at some point in the future."
Battery tech has also been improving recently. There's no reason that it may become much lighter in the future and a combination of PV and batteries may become practical. It's also entirely possible that PV will never reach the necessary efficiencies and batteries don't reach the energy density necessary. That's why I said "may" in both cases.
I would think it also depends on when the plane is flying. If it's entire trip is during daylight hours, and it's above the clouds as most larger aircraft flights are, then you may be able to use solar panels in place of the majority of the batteries. Plus you won't have to carry the weight (as much) in fuel.

You do reallze you just included all medical research that respects the confidentiality of human subjects?
As someone who has been involved in several hundred medical research projects (at various institutions), I'm calling BS on this. While some multi-center studies may receive data with patient identifiers, they will either be rejected or scrubbed of these identifiers prior to being added to the database and being analyzed. If an institution is too incompetent to do this, then I'd question the validity of their results anyhow.

Thanks for the correction. It doesn't surprise me as details on this crash seem to change from one report to the next.

Perhaps you haven't looked at windmills up close recently but there isn't exactly a pile of dead birds sitting below them.
Did you happen to hear that whooshing sound? It wasn't from a windmill.;-)
Cats kill at least an order of magnitude more birds than windmills do.
Yes, but the majority of those cats eat the birds. I haven't seen a windmill that can do that.

Why does everything have to do with weed?
Probably because if you zoom in on the third one to the left of center you can see Tommy Chong trying to spark it up. ;-)
