Injecting Liquid Metal Into Blood Vessels Could Help Kill Tumors 111

KentuckyFC (1144503) writes One of the most interesting emerging treatments for certain types of cancer aims to starve the tumor to death. The strategy involves destroying or blocking the blood vessels that supply a tumor with oxygen and nutrients. Without its lifeblood, the unwanted growth shrivels up and dies. This can be done by physically blocking the vessels with blood clots, gels, balloons, glue, nanoparticles and so on. However, these techniques have never been entirely successful because the blockages can be washed away by the blood flow and the materials do not always fill blood vessels entirely, allowing blood to flow round them. Now Chinese researchers say they've solved the problem by filling blood vessels with an indium-gallium alloy that is liquid at body temperature. They've tested the idea in the lab on mice and rabbits. Their experiments show that the alloy is relatively benign but really does fill the vessels, blocks the blood flow entirely and starves the surrounding tissue of oxygen and nutrients. The team has also identified some problems such as the possibility of blobs of metal being washed into the heart and lungs. Nevertheless, they say their approach is a promising injectable tumor treatment.

That it has. The current gen are impressive machines, as are the old ones, and kids love seeing them. It is like a Tonka truck dream come true, or as my 3 year old put it shaking with excitement "They have a super dump truck and a super super dump truck!" when he first saw the 100 ton and 240 ton truck up in Virginia, MN.

I was just countering that somewhat implied point that they weren't using massive machine. At the time they were using the largest available but those don't hold a candle to the current monsters that are used in mining the largest ever removed ~220 cubic yards of material at a time. Or for an actual shovel instead of a dragline there are these electric monsters which I have seen similar ones in action.

Well at the time they were using the most massive equipment available to the point that a whole new class of steam shovels was created specifically for the project. They were rail mounted 105 ton (US tons and that is the vehicle weight not capacity) steam shovels. You can see one of the 6 prototypes for the project here. It has a 2 1/2 cubic yard bucket instead of the original 5 cubic yard one (changed because the iron ore was substantially denser) and was also converted to crawler tracks to run in the iron mines of northern Minnesota but is the only remaining one of the prototypes. While this shovel never worked on the Panama Canal the only other surviving example of this type of shovel that may have is in much worse shape and exists in upstate new york. They were built on a 40' railroad box car which houses the boiler with an additional 8' added on to the back for a coal hopper with the boom and arm attached to the front.

Using your groups the actual numbers would be more like .00001% of the people on the list are in group C, .00002% of the people on the list are in group B, and the vast majority 99.99997 fall into group A (these number are at least within a couple of orders of magnitude of the actuals). This isn't a list of terrorists, but people with ties to terrorism with what ever criteria the rather incompetent government uses for defining ties to terrorists. I would be willing to bet it assumes 2 degrees of separation at least so you know someone who knows someone type of thing means you have ties to terrorism.

That assumes that the general probability of any random person has a 50% chance of having ties to a terrorist (I leave it to the reader to figure out what in the hell that actually means). In reality depending on how having ties to a terrorist is defined the list is either phenomenally accurate (nice tight definition where 80% of the general population meets the definition).

Comment Re:High success rate or lots of unknowns? (Score 1) 256

Not quite. Remember this is supposedly a DB of people with connections to terrorism which means you know someone who knows someone kind of thing. I am not sure how many degrees of separation one needs to not be considered to have connections to terrorism. I am surprised the number is as high as it is given the governments previous statements on such things, since I figured using their normal methods of classifying people they could have just loaded the U.S. Census Bureau DB and then claimed that only 0.001% had no connections.
