Abstract: This invention relates to partially ordered and ordered oxynitride perovskites of the general formula ABO2N that are polar insulators. A comprises one or more cations or set of cations that sit in sites derived from the A-site in the perovskite structure. B comprises one or more cations or set of cations that sit in sites derived from the B-site in the perovskite structure. C comprises oxygen, O, with optionally some nitrogen, N, and D comprises N, with optionally some O. The total valence of the cations A+B is equal to the total valence of the anions 2 C+D. Also disclosed are methods of producing such oxynitride perovskites and uses of such oxynitride perovskites.
Abstract: The invention encompasses methods for improving the level and/or sustainability of expression for a target nucleic acid in a eukaryotic cell comprising: (a) modifying the target nucleic acid to introduce or to comprise signals that limit or constrain the positions of nucleosome cores, and (b) introducing the modified target nucleic acid into the eukaryotic cell, wherein the modified target nucleic acid has improved levels and/or sustainability of expression compared to original unmodified nucleic acid.

Abstract: The invention provides fusion proteins comprising at least two fluorescent proteins, with the fluorescent proteins emitting different wavelengths of light from one another, at least one plant hormone binding domain that changes three-dimensional conformation upon specifically binding to a plant hormone, and two linker peptides, with the first linker linking the first fluorescent protein to the N-terminus of the plant hormone binding domain and the second linker linking the second fluorescent protein to the C-terminus of the plant hormone binding domain. The invention also provides for methods of using the fusion proteins of the present invention and nucleic acids encoding the fusion proteins.
Abstract: The present invention relates to a systems and methods of using expression of one or two luminescent proteins in a plant root cell to visualize plant root structure as well as to determine how stressors affect gene expression in plant roots while maintaining the natural soil habitat
Abstract: A process is provided of introducing an RNA into a living cell to inhibit gene expression of a target gene in that cell. The process may be practiced ex vivo or in vivo. The RNA has a region with double-stranded structure. Inhibition is sequence-specific in that the nucleotide sequences of the duplex region of the RNA and of a portion of the target gene are identical. The present invention is distinguished from prior art interference in gene expression by antisense or triple-strand methods.

Abstract: A method to measure the metabolic rate or rate of glucose consumption of cells or tissues with high spatiotemporal resolution using a glucose nanosensor is disclosed. The method generally includes providing single cells or cell populations, cells in suspension or adherent, in a cell culture, a tissue culture, a mixed cell culture, a tissue explant, or in animal tissues in vivo for the measurement of glucose metabolic rate; expressing a glucose sensor in individual cells; calibrating the sensor in controlled conditions; disrupting the steady-state of glucose entering the cell; recording the output from the sensor and calculating the corresponding glucose concentration at different times; and determining the glucose metabolic rate. The method can be applied for the screening of molecules with pharmacological potential, determination of glucose rate of cancerous cells, tissue physiology and biochemistry research.
