Despite the problems, many scientists still look to the future with
confidence, speaking optimisticly of major discoveries and breakthroughs
that will surely come in the years ahead.

The International Hearld Tribune reports :
The best hope for true breakthroughs, many scientists say ,
is biotechnology, the manipulation of hereditary material in liveing cells.

Scientists at biotech firms hope to create cells that produce germ-killing
substances , that is, a new generation of genetically engineered antibiotics.

There is , however, a dark side to this. Genetic engineering has made it
possible to insert genes into a harmless virus so that the virus can deliver
the genes to people.

This technology can be used beneficially, perhaps actually...
makeing possible the production of so-called genetically engineered antibiotics.

But this technology may also be used for sinister purposes....
