Rediscovery of the wild pig Sus bucculentus

Article Abstract:

A species of wild pig from Indochina, the Sus bucculentus, has been rediscovered in the Annamite Range in Laos, where new and previously undescribed large mammals have also been discovered. A partial skull of a juvenile male of the species was obtained from local hunters in Ban Ni Ghiang, a village on the Nam Gnouang, in Jan 1995. A comparison of a 327-base fragment of the 12S ribosomal mitochondrial gene and material from a local wild S. scrofa and a local domestic pig showed that the latter two differed at 24 sites from the S. bucculentus specimen.

Superfluidity in the picture

Article Abstract:

Experiments reveal that strongly interacting atomic Fermi gases, which make up atomic nuclei and the matter in neutron stars, enter a superfluid state at low temperatures. Some of the most fundamental processes in the Universe, including superfluidity in neutron stars, hydrodynamics in a quark-gluon plasma and string-theory predictions of minimum viscosity in any generalized system can be modeled using these experiments with precise control of spin populations and precision thermometry.

Rediscovery of the world's leggiest animal

Article Abstract:

The millipede species Illacme plenipes, an extremely rare species, comes the closest to having its namesake's mythical 1,000 legs and was not sighted since 1926. The arthropod class Diplopoda contains some 10,000 described species and is one of the most ancient groups of terrestrial animals and the rediscovery of I. plenipes at a time when sophisticated microscopes are available has revealed the fine-scale structure of a creature whose morphology is intricate.
