ALIENS are now no longer confined to our childhood fancy. Early last year, they were found floating some 41 kilometres above the Earth's surface - an area devoid of life. What's more, the aliens - a kind of fungus and two species of bacteria - are similar to commonly found soil microbes. These are the findings of a recent analysis of the organisms conducted by scientists from the Inter University Centre for Astronomy and Astrophysics in Pune, India, and the University of Sheffield in Britain, the UK.
Excess CO<sub>2</sub> in air retards plants growth
Issue Date: Feb 15, 2003
an unprecedented study may force certain countries to do some soul searching. Contrary to what a few policy makers advocate, the study reveals that high levels of atmospheric carbon dioxide (co2) can retard plant growth.
Is Asia polluting the US?

industrial emissions of Asia, particularly China, are a major source of mercury in rainwater that falls along the California coast of usa. So says a new study by researchers from the Santa Cruz-based University of California (ucsc). However, the researchers acknowledge that mercury in rainwater is not a health threat.

Issue Date: Jun 15, 2002
a new computer model by National Aeronautical and Space Administration (NASA) can now indicate exactly where rain or snow originate across the world. The model simulates water movement in the atmosphere around the world and traces it from the places where it evaporates to the places where it falls back to the Earth.
Deep impacts
Issue Date: May 15, 2002
over the past half-century, Earth's entire surface or the lithosphere has warmed up significantly and is gaining energy at approximately the same rate as the atmosphere and cryosphere (the portion of Earth's surface where water is in solid form such as sea ice, snow cover, glaciers, ice caps and permafrost). This was discovered during a recent study carried out by researchers from the St Francis Xavier University, Canada, and University of Michigan (u-m), Ann Arbor, usa.
Packing more power

scientists in Italy have discovered a new form of oxygen. In addition to the two well-known forms -- ozone and the oxygen molecules in air -- there is a third, they say, in which oxygen atoms are grouped in fours. If these results bear out then we might have a better fuel source for the future.
