Comment Re:Marrow? (Score 4, Informative) 25

I'm not sure if I was clear enough.
The way similar things have been used previously is they are butted up against real living bone, so the real bone, including the marrow, grows into the portion of the implant that is left open for this to happen.

Having something the same strength, density and hardness as existing bone has a lot of advantages. Each time the recipient moves the implant flexes against other things and a very hard surface grinds away bone into tiny pieces which can confuse white blood cells enough that they attack attached bone as well as the fragments, which means eventually hard implants end up being very loosely attached and need to be replaced with ones going into fresh bone.

Taking notes at a materials science conference twenty years ago has finally paid off :)

The internet belongs to the NSA, GCHQ and NRO. No data flows domestically or as international data in or out without their tracking it.

Indeed, but from various leaks it appears the NSA at least can't find their arse with both elbows so while they have stuff on a disk somewhere what are they going to do with it? They couldn't even spot the "Arab Spring" happening until they saw it on Fox.

Trump is the lesser of two evils. Why?

I thought I was being very explicit that there is not much point making that comparison. It's about choosing someone suitable and not the lesser evil.

Hillary, on the other hand, is a skilled politician who would wreck this country if she managed to implement only a fraction of her stated agenda.

Yes, yes, women wrecking the joint and all that - even though I think she is slime unfit for office aren't you going a bit far beyond ridiculous with the "wreck this country" line?

Are you pushing the line of "Hillary is bad too so vote for Trump?" Yes or no?

Putin wins no matter who gets elected. Nobody is seriously considering getting in his way.

What is amusing is that Trump is getting finance from Russian banks because others don't trust him. Another thing that is more depressing than amusing is that Trump does not see Putin for what he is or just doesn't care.

They typically replace bones only when they are so completely destroyed that there's no hope of repairing them surgically, where the only options are grafts, transplants, other forms of bone replacement, metal plates, or amputation. I would assume that this would be similar, but less problematic than those other approaches.

Comment Re:uhm, these are standard on most factories (Score 1) 161

but didn't include the scrubbers? So this is exciting how?

Scrubbers are for the NOx and SOx while precipitators are for dust, smoke etc.

If they were standard, or also fitted on vehicles, there would not be such an air pollution problem.

What you see there is a "libertarian" set of rules about pollution. Until you put something in milk that obviously is killing kids it's fair game.

Batteries are pretty good these days and you can put a lot of them on a bike. I had some students in 2000 who took the frame of a 125cc motorbike, stuck lead-acid batteries everywhere, fitted a motor and that thing could go. With the batteries of today you could get a lot more range with something that doesn't have to be very big - a Vespa sized thing is going to get you up hills.
