Knock on wood

AN ELECTRONIC woodpecker that can identify trees with hidden rot could save healthy trees from being damaged or felled. Foresters looking for rot normally have to drill a hole in the trunk and take a core sample. This damages the tree, so Geoff Lawday of Buckinghamshire Chilterns University College near London wanted to find a …

Switzerland, one of the more honest countries in Europe in terms of BSE, has been testing apparently healthy cows for the rogue prion that causes the disease, with a test fast enough …

Feedback

THE PRIZES that Feedback and the scientific establishment await each year with awe were handed out last week at Harvard University—the Ig Nobel Prizes, which reward dubious achievements that "cannot or should not be reproduced" in fields from peace to safety engineering. This year's festivities, sponsored by Annals of Improbable Research, highlighted the changing nature …
