Moon keeps Earth's tilt in check

Issue Date: May 15, 1993
WERE IT not for the Moon, the climate on Earth would be dramatically different, say French geophysicists who have studied the effect on climate of the Earth's obliquity. The term refers to the angle through which Earth's spin axis leans away from the perpendicular to its orbital plane. The obliquity influences the amount of annual solar radiation reaching the Earth's surface at a given latitude, and thus, its seasons.

STRUTTING and swimming through the Antarctic, some emperor penguins are working on a scientific mission: monitoring the sea resources of the polar region.

Computers set to conquer language barriers

Issue Date: Apr 30, 1993
EVEN AS European Community researchers are developing a powerful computerised translation system that promises to break through language barriers, scientists in Japan, Germany and USA are working on a telephone translation system whose implications for world trade are mind-boggling. Both systems are reportedly in the test stage.

Infant death linked to child-rearing habits

Issue Date: Apr 30, 1993
WESTERN infants are more likely to become victims of so-called crib deaths because they are far more frequently left alone to sleep than Asian children, a British study shows.

Helping addicts get through their withdrawal symptoms

Issue Date: Apr 30, 1993
MARIJUANA and heroin may be frowned on by parents and the police, but they do have a beneficial side for scientists.

Birth of a galaxy

Issue Date: Apr 15, 1993
THANKS to the Bubble Space Telescope, scientists can now actually see ancient galaxies being forI The instrument, unlike earthbound telescopes, can be aimed at galaxies 4 billion light years away. Because le the light that is picked up was emitted 4 billion years ago, it provides a view of the galaxy as it was then. Astronomers at USA's Carnegie Institution recently saw a galaxy cluster that was formed about 5 billion years ago, a third of the way back to the Big Bang, one of the theories used by scientists to explain the tic birth of the universe.
