The ABCs of ammonia

Sydney, August 12: AMMONIA is a colourless, highly irritating gas with a pungent, suffocating odour.

Eighty per cent of ammonia produced by industry is used in agriculture as fertiliser.

Ammonia is also used as a refrigerant gas, which was the case in yesterday’s incident in Tanjung Karang where six people died after a leak at a refrigeration facility.

Other uses of ammonia are to purify water and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals.

It is also found in many household and industrial-strength cleaning solutions.

Universe’s first black holes kept to a strict diet

Washington, August 11: A new supercomputer simulation designed to track the fate of the universe’s first black holes has found that the mysterious cosmic objects couldn’t efficiently gorge themselves on nearby gas, and thus had to keep themselves on a strict diet, starving in the process.

Ice cap melting fast

Tuktoyaktuk, August 10: The Arctic Ocean has given up tens of thousands more square kilometres of ice in a relentless summer of melt, with scientists watching through satellite eyes for a possible record low polar ice cap.

Warding off computer viruses requires serious sleuthing

Berlin, August 09: Ideally, every computer should have an anti-virus programme installed and every computer user should be vigilant about using and updating it.

But, it’s not a perfect world, which means people need to rely on early warning signals should something go awry with their computer.

Unfortunately, that approach is also starting to lose its effectiveness as modern computer viruses become even more pernicious.
