A new species of living bovid from Vietnam
Article Abstract:
The Vietnam World Wide Fund for Nature, in Ha tinh province, discovered three sets of long straight horns of a new bovid species. Subsequent surveys in Nghe province showed some partial specimens. Out of the 20 specimens examined, three have complete upper skulls and dentitions, two have lower jaws and dentitions, and three complete skins have been retrieved. Only two bovid genera are identified, and the rest are distinct species in appearance, morphology and DNA sequence.

The arrangement of the three cone classes in the living human eye
Article Abstract:
Human colour vision depends on short (s), medium (m) and long (L) wavelength sensitive cones which are interleaved in a single mosaic. The human L and M cone submosaics have been resistant to analysis. Adaptive optics and retinal densitometry have been combined to obtain images of the arrangement of S, M and L cones in the living human eye. In two male subjects, each with normal colour vision, the mosaics had large areas in which either M or L cones were absent.

For the living there is hope
Article Abstract:
The use of living polymerization techniques in the preparation of high-molecular-weight polypeptides and block copolypeptides is an exciting development in biomedical engineering. A variety of applications such as drug delivery will benefit from the research. The synthesis of polypeptides by ring-opening polymerization of N-carboxy-alpha-amino-acid anhydrides, involving block copolymers, is illustrated and described.
