IT WAS the year of the Beijing Olympics and the US presidential election. For the first time, two astronauts on the International Space Station cast their votes from space. Fortunately they made their choice electronically, otherwise the ballot box might now be orbiting the Earth, along with their colleague's tool bag.

It was a mixed year for the forecasters who use mathematical models to peer into the future. First the good news. They got the presidential election spot-on. Now for the bad news. They failed dismally to foresee the collapse of the financial institutions that had made so many of their number rather wealthy. And when the price of crude oil soared past $130 per barrel, most of them expected it to continue on an upward spiral. It's clearly too early to throw out the chicken entrails.

However, things could be far worse. Imagine if the next US vice-president was someone who thought human activity had a trivial effect on global warming, made George W. Bush look as if he had a grasp of geography, and whose views on evolution gave rise to a scientific neologism - palintology.

So as we bid good riddance to 2008, here's the traditional New Scientist quiz - a gentle amble through the year's stories, big and small. All you have to do is to sift the crackers from the turkeys.

5. Why are 200-metre sprinters more likely to win if they are drawn in the inside lane?
