    Motor proteins such as kinesin help to haul cellular cargo along microtubules, and they are mechanically programmed to move in one direction only -- towards either the rapidly growing plus ends, or the static minus ends. But what determines the direction of movement? To address this question, a chimaera has been created in which the head of a minus-end kinesin is attached to the tail ofa plus-end kinesin. And the chimaera moves in the opposite direction to the minus-end heads.

    How do people make decisions? A standard answer (not the only one) runs as follows: every individual first ranks all alternatives open to them, and then chooses the top of the list. This model had not been validated by econometric studies, but now a simple realization has changed that situation: two people don't act the same way as one. Indeed, the buying patterns of couples conform toentirely different sets of equations.

    When proteins are secreted from the endoplasmic reticulum (ER) to the Golgi apparatus, they are packaged into vesicles that travel to and fuse with the tubular network at the cis face of the Golgi. But what happens if the ER is a long way from the Golgi? An elegant new study using green fluorescent protein shows that the vesicles fuse to form a vesicular-tubular network, which travels down microtubules to fuse with the cis-Golgi network.

    Satellite monitoring of the extent of sea ice in the Antarctic began only in theearly 1970s: before that there are few other data to go on. An innovative study of the records of whalers, who made many of their kills at the ice edge where whales congregated to feed, now concludes that there was a large reduction in Antarctic summertime sea-ice coverage between the 1950s and 1970s. The cause of this inferred decrease is unknown. But it is a matter of considerable interest, as the sea-ice cover of the polar oceans is an important component of the Earth's overall climate system.

    A few weeks ago,Nature reported the sequence of Helicobacter pylori, which is present in up to one in three people and causes peptic ulcers. But many other chronic diseases or cancers are also thought to be caused by infectious agents. Weight is now lent to this theory by two studies that link coronary heart disease to the bacterium Chlamydia pneumoniae, and the implications of these findings are discussed.

    Sunspots are relatively cool regions of the solar disk where bundles of magneticfield lines break through the surface. A puzzling phenomenon was first noted by J. Evershed in 1909: spectroscopic observations of sunspots show a flow of material streaming across the face of the spot, only to perform a mysterious vanishing act at its outer edge. It turns out that the material is dragged back under the solar surface along closed loops in the magnetic field.

    With political parties in some countries moving ever closer in their policies, Daedalus suggests abandoning the pretence that party and policy are connected atall. A sophisticated polling system will gauge the will of the people, and parties can compete for votes solely on the basis of their bids to carry out those policies for the least tax.
