RADIO EXTRA STORIES FROM 8 MARCH 2003 ISSUE
 
RISKY TYPES OF HRT ARE IDENTIFIED Women taking particular forms of hormone
replacement therapy are at greater risk of developing breast cancer, a huge
study of Swedish women has confirmed. The greatest risks are posed by
"combination therapies" containing progesterone as well as oestrogen. Page 8
 
PHANTOM MENACE RIPS COSMOS APART 22 billion years from now the Universe
could come to 
a far more violent end than anyone dared to imagine, according to a British
scientist. He says a mysterious dark energy, called phantom energy, will
cause the runaway expansion of the Universe ripping apart galaxies, planets
and even atomic nuclei. Pages 14-15
 
JOJOBA IS MORE THAN A PRETTY FACE As well as being a popular base for
cosmetics, jojoba may be an excellent alternative to diesel fuel. Tests in
Egypt show jojoba-fuelled engines match diesel for power, but produce less
pollutants and run more quietly. Page 18
 
GLOBAL WARMING PUTS FREEZE ON REINDEER Climate change could be responsible
for reindeer deaths. Researchers in Seattle have found that warming causes
more rain to fall onto snow-laden pastures. The rainwater seeps through the
snow to form an ice crust over the soil surface, and reindeer and other
ungulates can't break through it to feed. Page 24
 
GENETIC TINKERING TURNS ONE SPECIES INTO ANOTHER By swapping chunks of DNA,
British researchers have turned one species of yeast into another, providing
the ultimate answer to the question of "the origin of species". Page 15
 
DEEP IMPACT How do you attack underground bunkers storing enemy biological
and chemical weapons? The Pentagon has the go-ahead to develop a new nuclear
bunker buster bomb, 80 times 
as powerful as the one dropped on Hiroshima. But surely there are
alternatives to the nuclear option? Pages 38-41
 
A SLICKER WAY TO CLEAN UP OIL SPILLS An engineer from the United Arab
Emirates has designed a tanker to recover oil lost at sea. It not only helps
to reduce environmental damage, but also produces a saleable product. Page

CUT SUGAR TO BATTLE OBESITY, SAYS REPORT UN experts say the best way to
tackle growing global obesity is to encourage people to limit sugar intake
to less than 10 per cent of their diet. New Scientist's free public website

SPAMBUSTERS Spam now accounts for 40 per cent of all email, so the battle is
on to find new ways to block it. At last somebody has had success in solving
the problem and he's calling for hackers to join him in the front line.
Pages 42-44
 
VIRTUAL WORKOUT BEATS THE BOREDOM FOR STROKE PATIENTS People who have
suffered a partial loss of arm or hand control after a stroke might soon be
able to log on to the Internet and run through rehabilitation exercises
designed by their doctor. Page 20
 
GLOBAL POPULATION FORECAST FALLS Falling birth rates and rising AIDS deaths
are stifling the population explosion-and could lead to a decline in global
population in the second half of the 21st century, according to UN
demographers. New Scientist's free public website at
