----------FEATURES---------
SHOCKED INTO LIFE
There is no doubt that asteroid impacts have an immediate
devastating impact on life. But in the long term, it is now
believed, they could be responsible for creating it. As impact
craters cool down, they become ideal spots for life to re-emerge,
and this has led researchers to ask if impact craters on the early
Earth provided the environment for life to evolve in the first
place. After all, they can provide the most important components of
a hydrothermal system in which Archaea-thought to represent the
earliest forms of life-thrive. Gordon Osinski, a geologist at the
University of New Brunswick in Canada takes up the story …

LET'S GET PERSONAL
What makes you the way you are? For centuries, philosophers,
artists and scientists have been trying to get to the bottom of
human personalities and why they vary so much. In recent years,
psychologists have got in on the act. And there is an awful lot
riding on something so poorly understood: your career,
relationships, happiness and health. Now it is the turn of molecular
biologists and neuroscientists. They believe they are starting to
discover the basic biological differences that create variations in
personality…

FRACTURED MINDS
We all have conflicting thoughts and feelings from time to time. We
experience mood shifts, and have ideas and desires that change from
moment to moment. Yet we mostly have a sense of a single, continuous
"me". Where does this come from? And how does it differ for people
who experience multiple selves? Rita Carter, author of
Consciousness, asks what these strange conditions reveal about our
sense of self…

PLAY IT LIVE
Are you the kind of person who can't bear fingerprints on your CDs?
Then don't lend your collection to Cameron Jones. He is a
mathematician at the Swinburne University of Technology in
Melbourne, Australia, who likes nothing better than to smear yoghurt
on CDs. He lets them dry and then sticks them back in the machine
and presses play. His bizarre methods could provide the newest tools
in musical composition and graphic design…

IN BRIEF
SLIMMING JAB
FAT people lose weight after injections of a naturally occurring gut
hormone called PYY3-36. In research published last week, 24
volunteers given a 90-minute infusion of PYY3-36 ate one-third fewer
calories than people given a placebo irrespective of whether they
were obese or not (The New England Journal of Medicine, vol 349, p
941). PYY3-36 is produced after eating, and acts on a part of the
brain called the hypothalamus to reduce appetite. It has already
been shown to help obese rats slim (New Scientist, 9 August, p 38)

Chris is on the Picture Desk. He arrived there from a photo library
and after doing freelance picture research for educational and
scientific book publishers. The job has changed enormously in the
last few years in that obtaining pictures is now virtually all done
via the web. He joined New Scientist in 1987.
----------PATENTS----------
STAR TEST FOILS FORGERS
An artistic pattern that conceals a subtle test could foil forgers
who copy the security print used on concert tickets, rail passes and
CDs (US 2003/0157305). Nigel Abraham, the British inventor who
dreamed up the idea, says the pattern contains several dozen small
stars, some with 30 points and others with 31. The brightness of the
stars also varies slightly in a way that encodes information about
which have fewer points. These differences are subtle and so cannot
be copied conventionally using digital scanning or photocopying. A
special scanner picks up the encoded information and also counts the
points on selected stars. If the results don't match the encoded
data, the item is a fake.

NO GOING BACK
Forget about that excellent adventure where you visit the ancient
Greeks or give your great-grandfather the fright of his life. The
idea of travelling through time is suddenly beginning to fall apart…
LAST OF THE LIONS
If people can't learn how to live with lions, we might well have to
live without them. We tell the sorry tale of the disappearing
predator
POWER FROM THE WAVES
In a unique test site off the Scottish coast, rival wave machines
will compete head to head as they feed electricity to the grid. We
report on big plans to lift marine energy off the drawing board
BETRAYAL OF INNOCENCE
People who deliberately harm their children to get the attention of
doctors are clearly sick. But is this controversial condition too
easily misdiagnosed? We investigate
