Just in time for life to spread under the protection of a stronger magnetic field.

Bush’s fault.

Until sciences next pull it out of their arse guess

[MUDDOG]

this flow of energy should keep the Earth's magnetic field going for another billion years or more.

That's reassuring.

[ClearCase_guy]

I think the standard estimate for the age of the Earth is 4.5B years.

So Earth was formed first, and then 3B years later, the core formed?

What?

[max americana]

Great. Send every liberal there.

"...is a likely indication..."

As usual, it's a theory that will be changed by some other study. I've so grown to distrust scientific studies that are often found incorrect.

Here's some examples from some of the greatest minds:
The world is flat;
The Sun revolves around the Earth;
Disease is spread by Satanic forces;
Aids will kill everyone;
Apple pesticides with Alacar were going to kill us;
Ozone hole over the antartica was the end of humankind;
World Population Bomb was going to kill humanity;
The next Ice Age portends the end of humanity;
Higher levels of cholesterol cause heart failure. Now it's saturate fats. No, now it's tri-glycerides;

Drinking a glass of wine a day is good for the heart, but drinking a glass of spirits is not. NOW, drinking any alcohol dilutes the thickness of blood which can cause blood clots;
Jogging is good for the heart. Oops, low impact exercise is now better:
Mars has no liquid water. Uh, now those experts claim Mars has liquid water.
Physicist claim the universe just poofed into existence from the "singularity". They have no idea how the singularity came to be.
Human caused global warming will flood low-lying areas because of melting glaciers and increase the overall temperatures of the planet along with increased hurricanes and such;
Human caused global warming will cause our next Ice Age;

My best example how wrong science can be is the 70's claim there is NO difference between male and female children. They claimed it was all NURTURE vs nature. It was on the cover of Time magazine. Recently, they discover there is a difference in the brain between males and females. Hell, anyone who raised a boy and girl saw the difference when toddlers - too young to influence. Even before this recent study, I saw an experiment back in the late 80's that had the Moms on one side of a short fence (think pingpong net on the ground) and the toddler boys and girls separately responding. The girls would cry when they reach the short fence because they couldn't get to Mom. Most of the boys would try to climb over it to get to Mom.

So now, the ever knowing Phd's tell us that there IS a difference between male and female. Thanks guys for your brilliant studies. I know I'm forgetting quite a few. Feel free to add to the above list where "scientists" were wrong.

"This increased magnetic field is a likely indication of the first occurrence of solid iron at Earth's centre and the point in Earth's history at which the solid inner core first started to "freeze" out from the cooling molten outer core."

Sounds like fusion to me.

[Up Yours Marxists]

This is all fine and dandy when scientists erroneously assume time is constant. As they always do.

It’s Settled Science™, after all.

[ought-six]

I remember that. It seems like just yesterday.

...1.5 billion years ago...

September 3, to be exact.

[capt. norm]

Not too sure about it being 1.5 billion years ago, but I do know it was on a Tuesday.

Hillary was wearing those gawd awful capris at the time, too.
