Dielectric mirror fibres
19 April 2002
Polymeric fibres exhibit excellent mechanical properties and are inexpensively
processed but controlling their optical properties is difficult. On the other
hand, dielectric mirrors can manipulate light in high-performance optical
applications but their fabrication is limited and costly. Researchers have now
combined these two systems and fabricated polymeric fibres with exterior
multilayer diele |

root and the CNS--the so-called dorsal root entry zone.
The study by Ramer shows that specific neurotrophic factors can inflence

blocks of flanking heterochromatin. However, the inner centromere of
Drosophila chromosomes is associated with blocks of nucleosomes that contain

Performance enhancement: Superhuman athletes
Enhancements such as doping are illegal in sport — but if all restrictions
were lifted, science could push human performance to new extremes.

Code breaking
Gene doping — enhancing performance by adding or modifying genes — has
been the subject of locker-room gossip for the past ten years. There are
plenty of natural mutations for which to wish. The Finnish cross-country
