25. Classical geometric resolution of the Einstein—Podolsky—Rosen paradox
I show that, in the geometry of a fiber bundle describing a gauge theory, curvature and parallel transport ensure and impose nonseparability. The “Einstein—Podolsky—Rosen paradox” is thus resolved “classically.” I conjecture that the ostentatiously “implausible” features of the quantum treatment are due to the fact that space—time separabil

26. No time loophole in Bell's theorem: The Hess–Philipp model is nonlocal
Hess and Philipp recently claimed [(2001) Proc. Natl. Acad. Sci. USA 98, 14224–14227 and 14228–14233] that proofs of Bell's theorem have overlooked the possibility of time dependence in local hidden variables, hence the theorem has not been proven true. Moreover they present what is claimed to be a local realistic model of the EPR correlations. If this i

27. POLYSACCHARIDE OF COCCIDIOIDES IMMITIS
Pappagianis, D. (University of California, Berkeley), E. W. Putman, and G. S. Kobayashi. Polysaccharide of Coccidioides immitis. J. Bacteriol. 82:714–723. 1961.—Soluble polysaccharide from mycelia or culture filtrates of Coccidioides immitis was found to consist mainly of mannose, but also included small quantities of galactose and another reducing sugar

28. Mutation of the gene encoding protein kinase C 1 stimulates mitotic recombination in Saccharomyces cerevisiae.
We have isolated a recessive allele of the yeast protein kinase C gene (PKC1) which promotes an elevated rate of mitotic recombination and confers a temperature-sensitive growth defect. The rate of recombination was increased between genes in direct repeat and at a series of heteroalleles and was dependent upon the RAD52 gene product. The mutant pkc1 allele

29. A polyoma mutant that encodes small T antigen but not middle T antigen demonstrates uncoupling of cell surface and cytoskeletal changes associated with cell transformation.
The hr-t gene of polyoma virus encodes both the small and middle T (tumor) antigens and exerts pleiotropic effects on cells. By mutating the 3' splice site for middle T mRNA, we have constructed a virus mutant, Py808A, which fails to express middle T but encodes normal small and large T proteins. The mutant failed to induce morphological transformation or gr

30. Organization of Enzymes in the Polyaromatic Synthetic Pathway: Separability in Bacteria
Ultracentrifugation in sucrose density gradients was employed to estimate the molecular weights and to determine possible physical aggregation of the five enzymes catalyzing steps two to six in the prechorismic acid portion of the polyaromatic synthetic pathway in six species of bacteria: Escherichia coli, Salmonella typhimurium, Aerobacter aerogenes, Bacill

31. Intron and upstream sequences regulate expression of the Drosophila beta 3-tubulin gene in the visceral and somatic musculature, respectively.
The morphogenetic programs involved in the differentiation of internal organs, such as the muscle system, during Drosophila embryogenesis have remained largely obscure. beta 3-tubulin has proved to be a good marker for mesoderm development as this tubulin isotype is detectable soon after mesoderm formation and during the process of mesoderm differentiation.

32. Extrachromosomal Element Delta in DROSOPHILA MELANOGASTER. VIII. Inseparable Association with Sensitive Second Chromosome
The presence of delta is always accompanied by a sensitive second chromosome in Drosophila melanogaster or vice versa. The separability of delta and the chromosome line was investigated in experiments designed to eliminate delta or to suppress its multiplication for a number of generations. Cy/Sb-5 males which transmit a minute amount of delta b (retained by

33. Glucose binding and transport proteins extracted from fast-growing chicken fibroblasts
Preconfluent or confluent fibroblasts grown in 5% serum medium yielded, without cell lysis, all the glucose-binding protein and most of the transport-stimulating activity in the cell wash fluid obtained with a 10 mM sodium octanoate-containing solution. For assay, octanoate was removed, and after the binding protein was labeled with [14C]glucose, the factors
