Not so green

CUTTING grass pollutes the air even if a hand mower is used, claim researchers in Colorado. Volatile organic compounds such as acetone and formaldehyde escape from freshly mown grass within seconds, and even more are released as it dries, according to Ray Fall of the University of Colorado in Boulder. Fall and his colleagues measured …

It's violent out there

Feedback

OUR ITEM about the motion-sensing lighting that plunged a conference into darkness when nobody moved (6 March) provoked a response that reveals a disturbing social problem. Two readers have been brave enough to tell us about their encounters with automated lighting in public toilets. Their stories are identical and may well be typical of many …
