Science & Mathematics - 16 December 2006

I just watched the Denzel Washington movie 'Deja Vu' one of the scientists in it said a process involving time travel was PHYSICALLY IMPOSSIBLE - even theoretically - and yet it worked because the two men believed in God.

Have any scientists witnessed any miracles in the lab with physical laws being broken down? I think maybe all we need to do is pray and God will rescind all physical laws for decent white christian folk. Any miracles in the lab been observed?

When you consider that they absorb chemicals through their
roots and all the crud that's in the soil, how is it possible that
they can survive?

I mean can anyone answer this without sending me to a math site, so that I can understand the best and easiest way to teach and learn this in just a few minutes or a short time? Are there any good tricks to it that I can use to help me learn it? I will also take good sites for learning this and other kinds of math as well, so if you have any to submit here that is fine and great too. I just want it simple so my kid can read this and learn it something you'd let your kid read it if you had one so they would learn it. If you are a kid that knows graphs and integers how did you learn them and how would you teach it to another student in your room that was having a problem understanding it?

I think it would be common in archeology and perhaps synonymous with a tell. I saw this word used as I read about the treasures from Afghanistan on display in Paris .

Massive discovery. Stunned scientists cure diabetes in mice overnight!
Quote

Diabetes breakthrough
Toronto scientists cure disease in mice

Font: * * * * Tom Blackwell, National Post
Published: Friday, December 15, 2006
In a discovery that has stunned even those behind it, scientists at a Toronto hospital say they have proof the body's nervous system helps trigger diabetes, opening the door to a potential near-cure of the disease that affects millions of Canadians.

Diabetic mice became healthy virtually overnight after researchers injected a substance to counteract the effect of malfunctioning pain neurons in the pancreas.

"I couldn't believe it," said Dr. Michael Salter, a pain expert at the Hospital for Sick Children and one of the scientists. "Mice with diabetes suddenly didn't have diabetes any more."

The researchers caution they have yet to confirm their findings in people, but say they expect results from human studies within a year or so. Any treatment that may emerge to help at least some patients would likely be years away from hitting the market.
