 RADIO EXTRA NEWSCIENTIST STORIES FROM 21 AUGUST 2004 ISSUE


PROTECTING COMPUTERS AGAINST 'EVIL' EMAILS A technique originally designed
to analyse DNA sequences is the latest weapon in the war against spam.
According to its developers at IBM in New York,
the algorithm named Chung-Kwei can catch nearly 97 per cent of spam. Page 23

HOW MINDS PLAY TRICKS WITH WORDS AND COLOURS Synaesthesia, a condition in
which a person has a mixing of the senses, may rely more on the plasticity
of the brain than on any genetic predisposition.
A study in the UK suggests that all of us are capable of having a
synaesthetic experience. Page 9

UNIQUE MOON MAY PARTNER SEDNA When Sedna was discovered in 1993, it was the
most distant object ever seen in the solar system and the largest since
Pluto was found. Now, British astronomers have calculated that if Sedna has
a moon, it must be more like a gigantic extinct comet than a planetary body,
and is possibly the darkest object in the solar system. Page 16

UK CLONERS TARGET DIABETES CURE Last week the UK granted its first licence
allowing scientists to try to clone human cells for research. Critics
denounced the plans as unethical and unnecessary. New Scientist reports on
the valuable insights such work could offer, for studies of diabetes and
other diseases. Pages 8-9

THE DOOMSDAY WRECK For 60 years the people of Sheerness in the UK have been
living next to a time bomb. A lethal mixture of unstable Second World War
bombs-equivalent to about 1400 tonnes of TNT-is in the rusting wreck of the
Richard Montgomery, a US cargo ship which lies half submerged in the Thames
estuary. If the cargo explodes, the blast will bring death and devastation
to a wide area. Pages 36-39

the inside of the nose may alleviate hayfever without the side-effects of
other remedies, say Russian and German researchers. New Scientist's free

COLOSSAL SURVEILLANCE NETWORK SHIELDS OLYMPICS An unprecedented array of
surveillance technology is being employed to protect the Athens Olympic
Games from terrorist attack. But some experts remain unconvinced the
measures are making the event any safer. New Scientist's free public website

HYDROGEN: SAVIOUR OR FATAL DISTRACTION Energy experts are bitterly divided
over whether developing a "hydrogen economy" should be the number one
priority, or if we should be investing in more immediate ways of cutting
carbon emissions, such as burying carbon dioxide. Page 12

SEXY MALES MAKE BIRD MOTHERS BETTER Female blue tits put in more parental
effort if the father of their chicks is attractive, a new Dutch study shows.
And the research team leader thinks the same might be true of humans. New

DATING WITHOUT DANGER A new system allows mobile phone owners to send
delayed text messages. If something should go wrong with a date, for
