'f've got squads of boffins waiting by phones the world over. They'll answer anything - recently they've made light work of the tyre pressure on the space shuttle, the smell of wet leaves and The Theory of Relativity. So get your thinking cap on, keep the question short, and have a bash at foxing a boff with a poser on a post- card. The address is on page 551. The world's longest tunnel >

Called a vertical axis turbine, the machine has been developed by Reading professor Peter Musgroven!Pt works a bit li3f an anemometer — those cups that whizz round to test wind speed — but has blades that can alter their angle instead of cups. It will be built in Wales, but Prof. Musgrove hopes versions will eventually be built at sea.

Boring the tunnel was a very hard job. It runs through0lbny different sorts of ground — some little more than mud — in an area prone to earthquakes. The Channel Tunnel, in comparison, would be a piece of cake. But Japan's amazing new tunnel could well be a spectacular waste of lives and money. It can carry a bullet train and a normal one at the same time — but critics say there is not enough demand from travellers to justify this. And there may not be t(— vast sums of money available now to finish off t(— tunnel. Getting the wind up >

DROPPING IN ON THE SHUTTLE Scientists on the space shuttle Chall- enger have carried out some successful experiments, despite faulty lasers, fuses, and plumbing. Crumbling rat food and flying droppings from the on-board mini-zoo have also caused problems. But NASA is still hailing the mission as the shuttle's most important science jour&—y ydt. It has filmed the Southern Lights, grown crystals, and done a host of other things. Baffle a Boffin > Kids Index - 407 Tea Time Quiz - 559 CARS FOR SALE 496 RECRUITMENT 498 PROPERTY FOR SALE 497

Neptu.j has a ring — or, at least, a ring with gaps in. Astronomers have been studying Neptune ever since the accidental discovery of rings around Uranus. But conflicting evidence from observatories around the world had just confused them. Now it seems that some telescopes spotted rings and others didn't because there were gapsn!And the partial rings — called arcs — could be moons in formation. Voyager 2 will pass nearby in 1989 and shed new light on the discoveries. Shuttle > Kids Index - 407 Tea Time (ziz - 559 CARS FOR SALE 496 RECRUITMENT 498  PROPERTY FOR SALE 497
