STORIES FROM 22 FEBRUARY 2003 ISSUE

 
US AIR FORCE PLANS NUCLEAR DRONES The US Air Force has decided to fund a
feasibility study into nuclear-powered versions of the uncrewed aircraft
successfully used in recent conflicts. A recent study showed that a nuclear
engine could extend the flight time of drones from hours to months. But 
the idea has raised serious concerns about the safety of flying radioactive
material over combat zones. Pages 4-5
 
X-RAY TRICK PICKS OUT TINY TUMOURS Tumour cells have a unique scattering
effect on X-rays, scientists at University College, London have discovered.
The team is using this telltale "signature" to develop a new type of
mammogram that detects tumours only 4 millimetres wide-as opposed to the
current 10 to 12-millimetre lumps. Pages 14-15
 

SPECIAL REPORT: SUNKEN OIL TANKERS One of more than 1000 wrecks from the
Second World War littering the floor of the Pacific Ocean ruptured in 2001
sending oil gushing to the surface, fouling beaches and polluting water. How
many more of these wrecks pose a similar threat to the environment,
including the Great Barrier Reef? Pages 12-13

 
OIL AND WATER DO MIX Oil and water will mix if you first remove any gas
dissolved in the water, according to a scientist at ANU. Chemists are
waiting to see if his work can be repeated. Page 17
 
MUNGO MAN HAS HIS SAY ON AUSTRALIA'S FIRST HUMANS A thorough analysis of the
burial site of Australia's oldest human remains could settle a dispute over
when humans first colonised the continent. The man from Lake Mungo in
southwestern New South Wales is now held to be about 40,000 years old, a
date which supports the "Out of Africa" hypothesis of how humans evolved and
spread. Page 15
 
WEIGH TO GO A kilogram is currently defined as the mass of a chunk of metal
kept in a safe in Sèvres, 
France. The CSIRO is heavily involved in the worldwide search to find a more
flexible replacement. Pages 32-35
 
PENGUIN DADS KEEP THEIR FISH FRESH To feed their chicks, male king penguins
keep undigested food in their stomachs for weeks. But how they do it has
always been a mystery. New analysis of stomach contents by a French team has
found the penguins keep food fresh by destroying spoilage bacteria in their
stomachs. Page 21
 
END COMPUTER RAGE WITH A MANUAL THAT MAKES SENSE The answer to
unintelligible software manuals is to use even more software, according to
CSIRO researchers in Sydney. They hope to revolutionise the standard of
instruction manuals by monitoring how people actually use software and solve
problems. Page 19
 
ANTIPODES: IT'S A SMALL WORLD Bob Johnstone tells the curious story of how
New Zealand and South Korea are collaborating in the field of
nanotechnology. Page 53
 
MOLECULAR SECRETS TO SPECIAL FORCES TOUGHNESS Special Forces soldiers are
more resistant to stress than usual because they produce more of a
particular compound in the nervous system, US researchers have found. See
