NewScientist 22 March Issue

DISMAY OVER CALL TO BUILD MORE DAMS Water experts have reacted angrily to
calls from the president of the World Water Forum to double the number of
large dams worldwide. They say such large-scale schemes will not serve the
poor who drink dirty water and have nowhere to get rid of their sewage. Page
11, and Comment and analysis, Page 27

COMPOSTING TOILETS KEY TO GLOBAL SANITATION, SAY SCIENTISTS Providing large
sewerage systems to communities in the developing world could be disastrous
for them and their environments. Sewerage systems are expensive, pollute
rivers, deprive farm soils of nutrients, and use a lot of drinking water,
say sanitation scientists. New Scientist's free public website at

GENE TESTS COULD SCUPPER BIOTERRORISTS A new gene-based technology may soon
allow exposure to mystery biological weapons to be identified within hours.
With such early detection the harm caused by biological weapons could be
substantially reduced, making them less attractive to terrorists. New

SYNAPSE CHIP TAPS INTO BRAIN CHEMISTRY Researchers in California say they
have created a silicon chip which can pump out a neurotransmitter to
stimulate nearby cells. The technique could open the way to implants which
interact with the nervous system, delivering drugs in a more precise way
than is possible now. Page 24

KYOTO CHANGES MAY DRIVE DEFORESTATION Proposed changes to the Kyoto Protocol
could cause widespread destruction of rainforest, according to Italian
researchers. The problem arises from allowing countries to meet their
greenhouse targets by planting forests on cleared land. Page 15

RISING CLOUD LEAVE FORESTS HIGH AND DRY Scientists have observed that over
the past 30 years, the base of the clouds that form over the north-eastern
US has been moving higher and higher. The change, due to deforestation and
urbanisation, could severely disrupt forest ecosystems. Page 18

'THERE WAS ZERO WE COULD HAVE DONE...' What will NASA do next time if a
future mission ends up in orbit, knowing that it cannot possibly land? There
are many things a crew can do to buy time for NASA to come up with a rescue
plan. Pages 34-37

CRYSTAL SWIMS LIKE A FISH TO ESCAPE FROM LASER LIGHT A stretchy liquid
crystal is intriguing physicists with its bizarre tendency to swim away from
light. Its unique property could be used to make robot submarines propelled
by light beams. Page 18

INTERNET TRAFFIC COPS COULD FOIL WEBSITE HACKER ATTACKS Microchip
manufacturer Intel says it can thwart denial of service attacks on websites
by means of an automatic response.

CAR CAM CATCHES CROOKS (short story) Engineers at electronics giant Philips
have suggested burying sensors in car bodies that will trigger wide-angle
web-cams to take pictures of those who dent or scratch parked cars. Page 21
