    Notes: [Auszug] THE determination of ever longer tracts of nucleotide sequences of viral and ribosomal RNAs has created as many questions as it has answered. The most striking achievements so far have centred on the RNA of the small phages of the R17 group. Adams, Spahr and Cory (Biochemistry, 11, 976; 1972) have ...

    Notes: [Auszug] THE space shuttle won its first test of Congressional opinion last week with considerable ease: a move to defer funding for the.-enterprise picked up only eleven supporters and 103 opponents when it was put to the test in the House of Representatives. The occasion was a debate on the authorization ...

    Notes: [Auszug] COST overruns on NASA's next planned solar physics satellite may have put the satellite in jeopardy, and NASA officials will decide in the next few weeks whether or not to cancel the main contract for the project. If the satellite is scrapped, it will probably signal the end of the orbiting solar ...
