Steinernema silvaticum sp. n. is described from woodland soil near Berlin, Germany. The species is quite common in European woodlands, being found in forest soil all over Germany, in Belgium, the Czech Republic, The Netherlands, Sweden and the UK. It was previously reported as Steinernema sp. 'B' in Germany and the Czech Republic, and as Steinernema sp. 'B3' in UK, Belgian and Dutch surveys. Third-stage infective juveniles are mainly characterised by a straight body of medium length (means = 700–900 μm), lateral fields with eight equal ridges (with appearance of nine parallel, equally spaced lines under light microscope), rather broad, flatly rounded and continuous cephalic region, excretory pore at level of mid-pharynx and average hyaline tail portion constituting ca half total tail length; males with mucronate tail, yellowish spicules of ca 50 μm length and wide manubria; females with short conoid tail with pointed non-mucronate tip. According to the ITS rDNA sequences, S. silvaticum sp. n. belongs to the 'feltiae-kraussei-oregonense' group of Steinernema species, although it is closest to S. kraussei. The new species shows a high level of nucleotide differences in ITS rDNA sequences from other steinernematid species and can be easily distinguished from S. kraussei, S. feltiae, S. oregonense, S. weiseri and S. jollieti by morphological characters of the infective juveniles and males.

The article presents an abstract of the research paper "Molecular Functions of Neurofascin, a Member of the LI Subgroup of Neural cell recognition molecules." It will be presented in the joint meeting of the International Society for Neurochemistry and the European Society for Neurochemistry that will be held in Berlin, Germany from August 8-14, 1999. Neurofascin is glycoprotein that belongs to the immonoglobulin superfamily.

The article reports on the research conducted by Klaus-Viktor Peinemann and colleagues on the sizes of membrane pores in Germany. Researchers found that the polymer in which the chain-like molecules have a hydrophobic and a hydrophilic end allowed the solvent solution to evaporate, thus forming into connected cylinders with hydrophobic and hydrophilic parts of different molecules coming together. When it was plunged in water, the nascent membrane moved through the hydrophilic cylinders, opening it up and creating identical and aligned pores. Picking other polymers with hydrophobic and hydrophilic parts allow the development of membranes with uniform diameter pores of various sizes.
