Just a comment about spinning fur. Wool can be spun very easily - even without a spindle - because the wool fiber is neither straight nor smooth. Fur is generally both straight and smooth. It can be spun but it requires much skill and is not work for beginners. I rather doubt that the art of spinning developed locally based on rabbit fur.

The LHC is a good many weeks away from reaching the point in their in their testing where they might be producing black holes. Right now they are running only one of the two beams at a time. So there's nothing to collide with. Sort of like clapping with one hand.

This same doomsday question has been asked before each and every step up in power: the first atomic reactor, the A-bomb, the H-bomb, and nearly every new accelerator including the predecessor to this one. The answer, each time, has been that nature has already run the high energy test. There are very few really high energy cosmic rays, but with billions of years to wait for one the test has al

This sentence needs one word added at the end: "economically"
We know how to make fusion work but we need to find out how that can be done economically.

The authors write: "Although there’s no direct way to measure ancient oxygen levels, some geochemical data suggest that levels have risen to as high as 35 percent and dropped to as low as 10 or 12 percent for significant intervals." Now I can't speak to the low level but the suggested high level of 35% is way too high.
Many moons ago I used to run a standard test called oxyg

I've seen suggestions that the younger Dryas was the result if a HUGE lake, encompassing all of the Great Lakes and then some, flushing down what is now the St. Laurence River. It was proposed that the fresh water floated on the top of the N. Atlantic salt water and shut down the heat engine that now keeps Europe so warm. That scenario is, of course, abrupt.

There is insufficient uranium in any building stone to be of any harm over your lifetime. BUT, if it really bugs you, use limestone or marble which usually have too little uranium to even measure.

The melting of floating ice sheets will NOT raise the level of the ocean. Therefore the melting of the Arctic ice is not a problem in and of itself. (Polar bears would probably disagree.) Nor is the melting of the Antarctic and Greenland ice sheets a problem for the same reason.
But, for example, it is postulated that the recent breakup of the floating ice sheet in the west antarctic will

Accidental explosions have not been a problem. See this large posting:
The principle advantage of geothermal vs solar or wind is that geothermal is available 24/7 like hydro. But as I said above, it is relatively dirty and you must have a place to dispose of the brine from the cooler.

Actually this is a lot of BS. Technically it is true, but the process is relatively dirty (brine disposal) and hard on the machines. Also there are few spots with their own volcano.
Wind power is also effectively unlimited and that technology has been advanced nicely in northern Europe but, as we have seen recently, a useful wind tower could go in YOUR backyard. And Americans are almost un

I suppose my comment might be considered political, but if there are few jobs for possible husbands, this might seem to the girls to be their best chance to become independent of their parents. Welfare in MA seems to be relatively generous.

I do not think this is real. If you can train bugs to make crude oil, seems to me that you should be able to modify the strain (or process) to yield diesel fuel directly and save the energy inefficient cracking and distillation steps.
Also note that there has been no publication in a refereed journal.

As far as I can see, the believers are claiming (in various ways) to have discovered fusion with NO byproduct radioactivity. Sorry but that is too big to swallow whole.

I don't know much about iodine deficiency but I do know that it is extremely rare in people living near an ocean. There is iodine in the fish, iodine in the herbs and grasses, iodine in the animals that eat the herbs and grasses and so on. Living on a small island they might be able to inhale enough iodine for their needs. If they are discussing an inbred genetic problem they should speci

For one thing, it sounds almost as if he is proposing to repeal the second law of thermodynamics. When he does that, he won't need little bugs to make energy. But I suppose he plans to use energy from the sun.
So a second point is that we already have life forms that turn CO(2) to fuel using energy from the sun...we call then plants usually.
