| | Astronomy: Twenty-five Years of Rocket and Satellite Astronomy 181
On October 10, 1946, a V-2 rocket, instrumented by the Naval Research Laboratory, was launched from White Sands, New Mexico, and carried an ultraviolet spectrograph above the ozone layer to photograph the solar ultraviolet spectrum. After twenty-five years of rocket astronomy, it is therefore appropriate to trace some of the history of astronomy from space platforms.

| | Genetics: Genetic Analysis of Developmental Mechanisms in Drosophila
187
The fruit fly Drosophila is being increasingly used in embryological experiments. Because of its well known genetics, and the ease with which the larvae can be manipulated in a variety of ways, it provides an ideal system for following such processes as cellular determination during differentiation, and cloning in morphogenesis.

| | Molecular Biology: Reverse Transcriptase, the DNA Polymerase of Oncogenic RNA Viruses 194
The excitement aroused by the idea that transformation of cells by RNA tumour viruses might depend on the activity of a reverse transcriptase enzyme(s) specific to the virus has stimulated much research since the enzyme was discovered in 1970. But the questions of the physical identity and catalytic activities of the enzyme(s), its function in transformation and whether it is unique to RNA tumour viruses remain unanswered.
