STORIES FROM 6 MARCH 2004 ISSUE

BEWARE THE ECOTOURIST The massive growth in ecotourism has biologists
worried. There is growing evidence of increased stress and changes in social
behaviour in many animals, which shows they do not react well to humans in
their backyards. In the long term the industry could endanger the survival
of the very wildlife the ecotourists want to see. Pages 6-7, and editorial

MEDICAL EDITORS TO TAKE TOUGHER LINE Editors of medical journals, who sign
up to a new British code of conduct, would be obliged to blow the whistle on
dubious or unethical research submitted for publication. They would be
expected to do more than merely reject the papers-for instance, inform the
research institutions where the research was undertaken. Page 11, and
editorial 

DNA CHIP WILL CATCH BEEFED UP CHICKEN A food ID chip which has been
developed in France can ensure meat products contain what they say they do,
and don't contain anything they shouldn't. Pages 12-13

THYROID RADIATION DOSES ARE 'MUCH TOO HIGH' Millions of people with thyroid
disease are being given excessive doses of radiation that could increase
their risk of contracting cancer. The Swedish Radiation Protection Authority
warns that doctors using radioactive iodine-131 to treat 
Graves disease-where the thyroid gland produces too much hormone-often
employ methods 
which overestimate the necessary dose. Page 10

CHEAP 3D SCANNER COMING SOON A British company has come up with a simple,
cheap device that generates 3D computer representations of any object it
scans. The company hopes the scanner will appeal to gaming fans who could
scan their favourite possessions and download them into the games they are
playing. Page 25

GRIEF ON THE REEF The Great Barrier Reef is on the verge of a massive
outbreak of coral bleaching as sea temperatures rise to high levels for the
third time in six years. Researchers in New York blame global warming, and
predict that this bleaching "will be the worst yet". Page 4

STRAIGHT AND LEVEL (short story) If its artificial horizon system fails, an
aircraft's autopilot should still be able to keep it level by sensing the
contrast between the darker land and lighter sky. Australian researchers
have developed a system to do just that. Page 25

THE MASTER SWITCH In theory, almost any brain disorder can be treated using
the brain's primary neurotransmitter, glutamate, as it is at the heart of
almost every central nervous system circuit. But for years researchers have
avoided drugs that target glutamate because they usually lead to horrendous
side effects. Not any more. There could be a medical revolution in the
making. Pages 34-37

ANTIPODES: THE SPOILS OF RESEARCH Ian Lowe looks at who profits from the
work of university scientists, and also at the hazards of volcanoes. Page 49

CELEBRITY "FRIENDS" KEY IN TEEN DEVELOPMENT Celebrity worship may play an
important part in growing up, a British study suggests. See also... Off
chasing comets; The oldest galaxy yet found; Superbug deaths on the rise.
