Pain relief
One of the best ways to stop pain is to get stressed. According to
scientists at Harvard Medical School the hormone noradrenaline which is triggered by a streesful encounter has a direct
effect on how the brain processes pain to produce analgesic - a painkiller. Tests revealed that noradrenaline was a
powerful suppressor of pain by activating specific parts of the brain.
Global warming
The tropics have expanded by 280 km in the past 25 years because of global warming. Researchers
claim. The change has happened much more quickly than scientist had predicted - previous estimates says the growth would
not happen until the end of this century.
Gas Alert
A device that can detect pollution and set off an alarm has been created by students at the University
of Glasgow. The biosensor acts like coal mine canaries, which used to warn workers of gas leaks. A microbe detects
gas, creating a chemical that makes a fuel cell generate electricity to trigger a warning sound. The device will be
able to spot leaks at oil pipelines, factories and landfill sites.
Thin Twins
Men who have a twin sister could be more likely to suffer from anorexia, a new study suggests.
The findings back the theory that exposure to female sex hormones in the womb may raise the risk of developing the eating
disorder, which is known to affect ten times more women than men. A British and Canadian team analysed data from a 33-year
study of twins.
Egg Yolk
The chemical that gives rotten eggs their foul smell could hold the key to a longer life.
In tests of nematode worms those exposed to hydrogen sulphide lived eight times longer than untreated worms. US scientists
hope the findings could lead to the creation of drugs that could delay the onset of age-related diseases in humans.
