Breaking down the barriers p863

Many Japanese researchers are concerned that they don't compete on a level playing field when it comes to international science. Language and cultural barriers may be partly to blame. But the perception is more forbidding than the reality.

Neuroscience: Addicted p872

"When you are addicted, there is no euphoria when you shoot up," explains Christian. "You only want heroin. Food and sex are not interesting. You are capable of being aroused, but you have no desire." Can neuroscientists explain why addicts feel this way? Alison Abbott investigates.

Japanese universities: Independence days p875

Japan wants to reform its university system, in part to match the competitive and entrepreneurial spirit of US academia. That won't be easy, says David Cyranoski.

Animal behaviour: When it pays to waggle p885

The waggling dance of honeybees conveys navigational information about where food is to be found. But it seems that the information is valuable only in certain circumstances.

Astronomy: Relic of the dawn of time p886

Elements heavier than helium are synthesized in stars. But could there be stars, created soon after the Big Bang, that contain almost no heavy elements? The discovery of such a star gives new clues to this early time.

Materials science: Nanomaterial advantage p887

Materials may be strong or ductile, but rarely both at once. The processing of copper into a nanostructure possessing different-sized grains produces a material that retains its high strength and ductility under deformation.

These are interesting times for those who study RNA. The latest curious discovery is that some messenger RNAs have sequences that sense small molecules directly, so controlling translation of the RNA into protein.
