nanotech in medicine realized

Under the direction of Professor Sylvain Martel, holder of the Canada Research Chair in Micro/Nanosystem Development, Construction and Validation, and in collaboration with researchers at the Centre hospitalier de l'Université de Montréal (CHUM), the Polytechnique team has succeeded in injecting, propelling and controlling by means of software programs an initial prototype of an untethered device (a ferromagnetic 1.5- millimetre-diameter sphere) within the carotid artery of a living animal placed inside a clinical magnetic resonance imaging (MRI) system.

human/sheep chimeras

Scientists have created the world's first human-sheep chimera - which has the body of a sheep and half-human organs.

He has already created a sheep liver which has a large proportion of human cells and eventually hopes to precisely match a sheep to a transplant patient, using their own stem cells to create their own flock of sheep.

But the development is likely to revive criticisms about scientists playing God, with the possibility of silent viruses, which are harmless in animals, being introduced into the human race.

Dr Patrick Dixon, an international lecturer on biological trends, warned: "Many silent viruses could create a biological nightmare in humans. Mutant animal viruses are a real threat, as we have seen with HIV."

Hexagon on Saturn

I think it's a scouting station, until They come.

 It is pretty damn cool though.

scientists playing God

Well, if they're playing God at a game of dice ... yeah, Science is in trouble.

twister is a much better choice.

Plus, I forgot Einstein told us in no uncertain terms that God doesn't play dice.

Sometimes S/He plays a mean game of billiards using asteroids and comets; if you wanna know how mean, I suppose you need to ask a dinosaur.

As in, ask a dinosaur

Might not play dice, but he's a whiz at Scrabble.

Last night I read my kid a bit from one of his books which says that the current big bang theory says that the universe started off the size of a marble before it exploded. I know this might stray into theology, if we're not careful - but what are your all favourite scientific theories of what was there before the big bang, where did the marble come from and why did it explode?

Answers on a postcard, please....

Magic.

The dinosaurs got wiped out for conducting cloning experiments? But, but, I thort the dinosaurs were walking around with man. After all the earth is only 6000 years old, right?

I thought there was only one theory which is that there really was nothing. But the idea of nothing is quite hard to get one's head around because it involves not just no stuff, but no space for the stuff to exist in, or time in which it could exist from and 'til.

Interestingly this is the one area where I think science and theology are equally clueless as I can't imagine a sensible answer to the questions 'What was there before God?' or 'So who created God?' except 'he's always existed, which suggests the further question 'So why did he decide to create everything when he did and not before?'.

damn I could make a lotta money if that actually existed!

It came from the place that stray paperclips and lint comes from.

Real answer, it came from nowhere, and there just isn't any "why." The thing is itself.

I always assumed the material in the 'marble' was the remains of the past universe. All the stars had burnt out and turned to black holes that all compressed into each other until it exploded again.

thats the circular universe theory or constant colaspe and expand theory,

though it has been marginally discounted as currently the stars are heading outwards too fast and far to allow for a collapse (which sorta sucks as it was my favourite theory too).

yeah, cos it would be a wild ride to see stars collide!

But who's to say a few stars on the edges don't burn out early, turn into black holes, start reining things in from the edges, slow things down, just enough for other stars to collapse, more black holes to form in the middle, center, and things start pulling back?

Honestly, I've never given much thought to this, whether science or in my theological thinking (as this isn't an important religious question for me) but I've never heard of this circular universe theory, and I think it's interesting I think it still begs the question of who started the yo-yo bouncing, or where the yo-yo came from in the first place, but the idea that this could just be one of countless/endless cycles of expansion and collapse, and for us this is our reality, but that it's all been done before, differently (or not), is very intriguing. I'm rambling. It's too early and too little coffee yet this morning for this

Yeah JP the theories of the Big-bang or start of universe do share one thing in common:

There is no "start" it is a human concept based on our own world experience, from what i've learned regarding quantum mechanics, you have to try to discard the whole "start" idea.

In that either the big bang happened and it wasn't a start so much as a happening or some such thing, its all a bit over my head to be honest.

But yeah with the circle/cyclical universe thing, there would be no start or end just cycle upon cycle.

. . .

And how is it that I'm the one who'd be accused of using a tautology if I said how I though the universe began?
