Solar Storm
Warning: You Have a Year to Prepare
Posted by Harry Fuller
The federal government now
predicts a new cycle of solar storms will start in March 2008.
Those storms are expected to peak around the end of 2011. That's
the conclusion of some scientists at NOAA.
Solar storms lead to violent eruptions on the sun's surface.
There'll be solar flares and explosions sending highly charged
matter toward Earth's atmosphere. This jolts Earth's geomagnetic
field and ionosphere. That can lead to disruption of electric
grids and communications systems.
Sunspot predictions for this coming storm cycle run from 90 to
140. There were different prediction models among the scientists
and that led to disagreement over how strong the next solar
storm cycle might be. Stick around, we'll find out.
Machine May Help
Shed Pounds Without Sweating
Turbosonic Only 10
Minutes To Burn Fat
by Christine Chang, 7 News Anchor
Sweating off the pounds might be a
thing of the past with a new machine that promises to shed
pounds simply by standing on it.
"You can stand on this machine for
10 minutes and it's equal to 45 minutes to 60 minutes of typical
exercise," said DeepTone instructor Jennifer Ament.
Ament said TurboSonic uses sound
waves that produce frequencies to stimulate your cells. She said
a person can burn up to 300 calories in 10 minutes, and that's
why people shouldn't be on it for more than that.
"It's equal to 60 minutes of
exercise so you'd be just overdoing it," said Ament.
"I lost 9 pounds, a pants size,
which is very exciting and I noticed my face tightening," said
Kelly Walton.

British Team Grows
Human Heart Valve From Stem Cells
by Alok Jha, Guardian Unlimited
Tissue for transplants could be
available within three years if trials are successful
A British research team led by the
world's leading heart surgeon has grown part of a human heart
from stem cells for the first time. If animal trials scheduled
for later this year prove successful, replacement tissue could
be used in transplants for the hundreds of thousands of people
suffering from heart disease within three years.
Sir Magdi Yacoub, a professor of
cardiac surgery at Imperial College London, has worked on ways
to tackle the shortage of donated hearts for transplant for more
than a decade. His team at the heart science centre at Harefield
hospital have grown tissue that works in the same way as the
valves in human hearts, a significant step towards the goal of
growing whole replacement hearts from stem cells...

Report Details
Global Biological Change
Associated
Press, Live Science
From the micro to the macro, from plankton in the oceans to
polar bears in the far north and seals in the far south, global
warming has begun changing life on Earth, international
scientists will report next Friday.
"Changes in climate are now affecting physical and biological
systems on every continent,'' says a draft obtained by The
Associated Press of a report on warming's impacts, to be issued
by the Intergovernmental Panel on Climate Change (IPCC), the
authoritative U.N. network of 2,000 scientists and more than 100
governments.
In February the panel declared it "very likely'' most global
warming has been caused by manmade emissions of carbon dioxide
and other greenhouse gases.
Animal and plant life in the Arctic and Antarctic is undergoing
substantial change, scientists say. Rising sea levels elsewhere
are damaging coastal wetlands. Warmer waters are bleaching and
killing coral reefs, pushing marine species toward the poles,
reducing fish populations in African lakes, research finds...
