Graptolites come to life
Article Abstract:
A pterobanch found in New Caledonia is believed to be a descendant of the now extinct animals called graptolites. The new species called Cephalodiscus graptolitoides has a long spine on its skeleton called nema which is very similar to that found in the extinct animals. The main debate on the relationship between graptolites and pterobanchs now focuses on the issue of how the nema is grown.

Electrical solitons come of age
Article Abstract:
Modern digital communication systems use optical fibers or individual packets of light energy known as optical solitons, for fast transfer of data. The quest to find more routes for data transfer led electronic solutions, which are simpler to produce than optical fibers, as they can be manufactured by standard integrated-circuit technology.
