Animal welfare | Nuclear fusion | Atomic waste | Managing investments | What’s in a name?
While I am, of course, concerned about the risks posed to the UK’s delicate biosystem by the inadvertent importing of harmful fauna and flora from foreign countries, your article (Colombian tree frog found by Sheffield florist highlights invasive species threat, 17 January) left a vital question unanswered.

• Intrigued to read about the government promising a record investment in nuclear fusion (Ministers pledge record £410m to support UK nuclear fusion energy, 16 January). Reminds me of the old joke: fusion, for the last 70 years, has always been 20 years in the future – perhaps an experiment to prove time doesn’t exist in nuclear physics?
