(EMBARGO: NOT FOR PUBLICATION BEFORE 06:00 AEST THU 10/02/2005)


DO THE LOCOMOTION Segway, the two-wheeled scooter launched in 2002, didn't
exactly revolutionise city transport, but it has had a serious impact on
robotics. Robot engineers have been learning from Segway's ingenious sense
of balance. Pages 34-37

LIGHT-EMITTING LINE REELS IN THE BIG FISH Anglers will soon be able to check
their fishing line for any sections close to breaking point by examining it
under UV light. The new line, developed by American researchers, contains a
type of polymer which fluoresces under UV light. Crucially, when the
material has been under excessive stress it glows green. Page 22

AND NOW FOR THE PODCAST Podcasting is a new piece of software that
automatically downloads audio files newly posted on the Web to your iPod or
MP3 player. Its UK-based creator says it saves you from sitting at a PC
manually downloading tracks and transferring them to your player. It can
even download for you while you're asleep. Page 24

VISIBLE MEMORY (short story) When you take a memory card out of a digital
camera there is no way of knowing how much free space is left on it. Kodak
has come up with a new breed of memory card which includes a liquid crystal
display on top showing that information. Page 23 

SELLING OUT American education researcher Jennifer Washburn says we should
be far from pleased that universities are increasingly business-minded. The
openness of university of life is suffering, curiosity-driven research is
being pushed out of the way, and disciplines are being sorted into haves and
have-nots. Page 19

THE HARD DOPE ON THAT RUSH OF BLOOD Marijuana really does give you a
headrush. Blood flows faster through the arteries of the brains of frequent
users than of non-users. A US research team says this might explain why the
drug affects short-term memory. Page 17, and New Scientist's free public

TB VACCINE HOPE An experimental DNA vaccine against tuberculosis developed
in South Korea speeds up recovery when given to mice alongside existing
treatments. It also prevents relapse and greatly reduces the severity of the
disease if animals are reinfected. Page 16, and New Scientist's free public

FOXES MAKE BETTER DOGS THAN WOLVES (short story) Man's best friend could
easily have been a fox. They are as readily tamed as dogs, according to an
international study, and just as good, if not better, at understanding human
cues. Page 17 

THREE IS THE MAGIC NUMBER ALPHABETS HAVE IN COMMON (short story) The scripts
of most languages demand an average three strokes per character, say two US
researchers who studied 115 different alphabets.  Three is also the biggest
number our brains can recognise without counting. Page 16

MENAGERIE OF MUMMIES UNWRAPS ANCIENT EGYPT A new collection of mummified
creatures-cats, birds, baboons, crocodiles-could help unravel some of the
mysteries surrounding ancient Egyptian society, say British researchers. New
