Opinion
US should back research cloning p103
The US Senate is expected to vote on legislation that would ban cloning by the end of this month. Supporting cloning for research is both right and in the national interests of the United States.

Biogeochemistry: A lowdown on oxygen p127
We can hope that the term 'palaeophosphatometry' won't catch on. The approach it describes has nonetheless delivered a plausible — if partial — answer to one of the main questions about Earth's history.
John M. Hayes

Cytoskeleton: Microtubules do the twist p128
As plant life diversified during evolution there would have been intense competition for light, making the ability to twist and climb advantageous. A subcellular filamentous network can create the twist seen in climbing plants.

Physiology: The pitfalls of power laws p131
The conundrum of how an animal's metabolic rate is related to its size continues to exercise biologists. A possible solution that takes into account differences during rest and exercise deserves attention.

Applied physics: Bridge for the terahertz gap p132
A device has been invented that produces radiation in the terahertz range. It is a considerable feat of semiconductor fabrication, and could be used in a wide range of applications.

Palaeoecology: Climate records spruced up p133
Pollen analysis is a valuable tool in helping to reconstruct past climatic conditions. Such studies can be informative on local as well as regional scales, as findings with fossil spruce pollen in Maine show.

Cell biology: Keeping the genome in shape p135
Chromosomes adopt their well-known form only at a certain phase in the cell-division cycle, just before they separate. But the proteins that help shape chromosomes also seem to be at work earlier on.
