(Case Western Reserve University) A team of theoretical and experimental physicists, with participants from Case Western Reserve University, have designed a new black hole simulator called BlackMax to search for evidence that extra dimensions might exist in the universe.

| • | Isolation and Some Properties of New Xylanase from the Intestine of a Herbivorous Insect (Samia Cynthia Pryeri) |
| Xylan the major portion of the hemicellulose of plant cell walls are heterogeneous polysaccharides. Xylanases are enzymes obtained from different species of microorganisms that degrade the xylosidic linkages of xylans backbone producing xylose with other monoresidues. In this study, xylanase producing strains were isolated from intestine of a herbivorous insect at Rajshahi University Campus. The strains were isolated on xylan agar media and screened by -xylanolysis method. Zymogram analysis was confirmed the xylanolytic activity. The strains was identified to be Aeromonas sp. and xylanase enzyme was detected in the culture supernatant of the strain. Xylanase enzyme was purified from culture supernatant of Aeromonas sp. by ammonium sulfate precipitation, gel filtration on Sephadex G-100 followed by ion exchange chromotography on DEAE-cellulose. In DEAE cellulose column chromatography, three protein peaks F-1a, F-1b and F-1c were appeared. Among these peaks, only F-1b showed xylanase activity and the degree of purification attained 64.54 fold. The purified enzyme gave single band on SDS-polyacrylamide gel electrophoresis indicating its homogeneity. The enzyme gave maximum activity against xylan as substrate at pH 7.0 and temperature at 55C. The Km value of xylanase was found to be 0.91% using the oat spelt xylan as substrate. The xylanase hydrolyzed strongly oat spelt xylan and birch wood xylan but didnot hydrolyze cellulose, carboxymethyl cellulose and starch. Xylose was detected as the hydrolysis products of oat spelt xylan by the xylanase. | |

| • | Does codon bias have an evolutionary origin? |
| Background: There is a 3-fold redundancy in the Genetic Code; most amino acids are encoded by more than one codon. These synonymous codons are not used equally; there is a Codon Usage Bias (CUB). This article will provide novel information about the origin and evolution of this bias. Results: Codon Usage Bias (CUB, defined here as deviation from equal usage of synonymous codons) was studied in 113 species. The average CUB was 29.3 ± 1.1% (S.E.M, n = 113) of the theoretical maximum and declined progressively with evolution and increasing genome complexity. A Pan-Genomic Codon Usage Frequency (CUF) Table was constructed to describe genome-wide relationships among codons. Significant correlations were found between the number of synonymous codons and (i) the frequency of the respective amino acids (ii) the size of CUB. Numerous, statistically highly significant, internal correlations were found among codons and the nucleic acids they comprise. These strong correlations made it possible to predict missing synonymous codons (wobble bases) reliably from the remaining codons or codon residues. Conclusion: The results put the concept of "codon bias" into a novel perspective. The internal connectivity of codons indicates that all synonymous codons might be integrated parts of the Genetic Code with equal importance in maintaining its functional integrity. | |
