RADIO EXTRA: STORIES FROM 27 MARCH 2004 ISSUE


A MIRROR TO COOL THE WORLD Climate scientists are starting to take a very
serious look at various global "mega-engineering" technologies to stave off
global warming. The fastest way would be to reflect solar radiation away
from our atmosphere and back into space, perhaps using a giant mirror. Pages
26-29, and Editorial...see also GREENHOUSE GAS LEVEL HITS RECORD HIGH The
level of the major greenhouse gas, carbon dioxide, has hit a record high in
the Earth's atmosphere, US government scientists have reported. And the data
suggests the rate of increase of the gas may have accelerated in the past
two years. New Scientist's free public website at

IT'S LIFE JIM... If there is life on Mars-it's there because we put it
there. After studying whether organisms can survive sterilisation procedures
used on space probes, an American scientist says there's a chance that some
Earth bugs hitched a ride to Mars and might still be living there. Page 5

THE WEIRDEST LINK Many physicists are now using entanglement-the spooky
connection between two particles across the Universe-as a technological
tool. But it seems we have only just scratched the surface of the potential
of entanglement and the effects it has on materials-and it's about to get a
whole lot weirder. Pages 32-35, and Editorial 

GO FOR GOLD, NOT A BAD CASE OF SWIMMERS' ITCH Competitors at this August's
Olympic Games could return home with more than their medals. They are almost
sure to share their bugs, a British specialist in infectious diseases warns.
And the water sports are especially perilous. Page 9

3D ADS TO PUT VIRTUAL BEERS ON BARS Three-dimensional foaming glasses of
beer could soon leap out of TV screens and on to bars, to tempt customers
into buying drinks. A new American 3D imaging system makes images appear to
jump up to a metre in front of the screen, where they can be viewed with the
naked eye from an angle of up to 120 degrees. New Scientist's free public

RFID CHIPS WATCH GRANDMA BRUSH TEETH Tiny computer chips that emit unique
radio frequency IDs could be slapped on to toothbrushes, chairs and even
toilet seats to monitor elderly people in their own homes. New Scientist's

PSST, WANNA SAFE BET... If you're thinking of taking a punt on a
steeplechase, pick a horse that has already been round the course without
falling, says a British veterinary scientist. It is twice as likely to
finish the race as a horse that has never run the course before. Page 9

DID ANCIENT HUNTERS KILL OFF THE MAMMOTH? Mass killing of mammoths by the
ancient Clovis people of North America was unlikely to have driven them to
extinction, according to an American study. Scientists measured isotopes of
elements in fossil mammoth teeth from three old Clovis sites. The study
suggests the animals were all unrelated and killed over a long period of
time. Page 16

DID BUTTERFLIES FLUTTER AROUND T. REX Ancient butterflies exquisitely
preserved in amber hint that the group evolved far earlier than previously
thought. They may even have fluttered around the heads of dinosaurs, more
than 65 million years ago. Page 17, and New Scientist's free public website

TV YOU CAN CLICK ON (short story) Buying the same jacket as that worn by
your favourite singer may soon be simply a matter of clicking on it while
watching a concert on TV. A Russian company has developed software to turn
any object on screen into a clickable item. Page 22
