Scientists found that blue tits, collared flycatchers and pied flycatchers can notice flickers as fast as 140 Hz. How would a speeding Usain Bolt look for them?
The overarching sense is that it is religious practice and use, rather than ecology, science or animal cognition, that is the shining light for subliminal but broad changes in our environmental policies.
One reason to expect the three genes used in transgenic mustard to be safe is that they aren’t new at all. They have been in the human food-chain for around two decades now.
The idea of a shared space is the best way to respect our histories, our traditions of peaceful engagement, the cultural geographies we inhabit — all with blurred and indistinct boundaries and interrelated contexts of meaning.
