Last week's resignation of Dr David Baltimore is a sad business. His obstinate defence of a research paper may have been the chief cause, but others must shoulder some of the responsibility.
Soviet science is on the verge of collapse. That is the message from Moscow in the past few days. The gloomy news is plausible. The rest of the world must do what it can to help, but with discrimination.
British and US institutions have separately challenged the notion that the nucleotide sequences of the human genome should be an open book; have they also signalled the end of the age of innocence for the new biology?
How will the world cope with the rash of new nations? Israel's tentative scheme for the West Bank, which proposes separate governments and separate taxes in the same land, will not often work.
Next month's meeting of European governments at Maastricht is billed as being the gateway to a more coherent European community, but it will be only if governments can suppress their ill temper.
A scientific panel of the US National Research Council has shown that too little of what passes for environmental clean-up meets the test of scientific rigor, while a US court overturns a ban on asbestos.
The Soviet Academy of Sciences has opted for allegiance to the Russian Republic rather than to what is left of the central government, but that by itself will not put things to rights.
