Reports oI close encounters with tlylng saucers, bug-eyed green aliens and giant sprouts lrom outer space have generally been taken with more than a pinch oi salt, but astronomers believe it’s likely that there are other living inhabitants at our vast universe. In ‘The Search Ior Extra-Terrestrial Lile’ (Wednesday 4 April, see listings) Archie Roy, tormerly a professor at Glasgow University, will describe our eltorts to resolve the mystery. He believes we should continue the search for tile even within our Solar System - and that Mars is the place to look.
Previous spacecratt landings have lound the Martians to be a little elusive, but there Is optimism that the manned expeditions planned by the Americans and Russians within the next fifteen years may tlnd evidence ol lite. ‘It's important to search tor lite on Mars simply because even it we lound a little piece at moss or lichen, it would be enough to tell us that tile had started on other planets, and is theretore almost certainly ten-a-penny throughout the universe.‘
Despite its heavenly name, Venus, our other neighbouring planet, is closer to a recreation oi hell. The planet’s scorching sulphurous heat is a result oi an atmosphere composed almost entirely oi the gases which are now producing the greenhouse ettect on Earth. ‘It’s conceivable that lite once existed on Venus. The runaway greenhouse ellect there, is perhaps a

salutory warning to us all.’
Farther away, the signs oi aliens are more dilllcult to detect, but any technological civilisation living on a planet orbiting one ot the several dozen stars closest to the Sun will know we are here because tor the last thirty to torty years, strong radio and television signals have been moving straight out from the Earth into space. ‘II there‘s a technological civilisation about thirty light-years away,’ says Roy, ‘lt’s picking up the iirst episodes oi Coronation Street.’
Roy believes they will understand our messages because any other civilisation is almost certain to be more advanced than us. ‘It the universe were one year old, then our last tour centuries ot science would have
occupied halt a second in that year‘. An I
allen society is likely to have had enough time to colonise the whole galaxy; they should be walking down the streets of every country In the world. Are they hiding from us or do they not get past the critical point In evolution when technology leads to destruction?
Perhaps they‘re just not very impressed with Coronation Street, but their own equivalent may soon receive our critical attention. Roy believes It may soon be possible tor our radio telescopes to detect the electronic ‘pollution’ oi other clvilisations In the universe. (Hazel Muir)

ll somebody were to compile a list ol overused scientitlc buzz words tor the Eighties, then superconductivity would appear tairly high upon it. Despite promises that it would revolutionise, amongst otherthlngs, power transmission, the only evidence most oi us have seen oi it are laboratory demonstrations oi weird and wonderful physical phenomena.
Prolessor Donaldson ot the Unlveristy ot Strathclyde’s department ot Pure and Applied Physics, sets out to explore some at their actual uses, and the possibilities tor the tuture, starting, oi course, with what superconductivity actually is (4 Apr, see listings).
Superconductivity can be used in large-scale electrical engineering projects tor the transport oi power, and also the storage ot energy in large magnetic lields. This can be easily demonstrated by a superconducting magnet producing a large field without external power sources. The energy held in this lield can be released in a controlled way, with many uses in relation to the storage and transmission ot power.
On a smaller scale, Protessor Donaldson has a demonstration ot SDID’S (possible buzz word tor the Nineties) which are used to detect magnetic tields in the human body. Whetherthis entails members ot the audience swallowing lumps ot superconductor, I am not sure, but luckily this technology is only used tor cardiology research at present. Other uses tor small-scale semiconductors include the development ot more powerful computers, although this will not be tor some years.
This promises to be an excellent general lecture in a lascinating tield which is at the cutting edge of science. It will be well supported by a series oi demonstrations supplied by Dxtord Instruments, so that the audience can witness tor ltselt some of the strange phenomena associated with this area at research.
