Argues that much of what is used currently to teach about multiculturalism in art consists of art made "long ago" or "far away." Presents four contemporary art works incorporating elements of mass media, popular culture, and diverse artistic traditions. Includes four full-page color photographs of the art works. (CFR)

The first meetup for Computational Stem Cell Biologists was held at the 2020 annual meeting of the International Society for Stem Cell Research. The discussions highlighted opportunities and barriers to computational stem cell research that require coordinated action across the stem cell sector.

This list of audiovisual materials on educational testing and assessment has been compiled from a variety of sources; the primary source was the National Information Center for Educational Media's Index to 16mm Educational Films, 1977 edition. Although the items are annotated, no attempt was made to review or to endorse any of the materials listed. Each bibliographic citation includes the title, annotation, name and address of publishers/distributor, year of publication, type of media, and length--for example, 2-inch videotape, 30 minutes, color. The item's price (rental or purchase) is indicated in some instances. The four sections in this bibliography describe 5 videotapes, 28 audiotapes/records, 32 filmstrips, and over 50 films. Topics covered include intelligence testing; achievement tests; personality tests; testing of multiply handicapped students; college entrance examinations; and instructions for constructing, administering, taking, and interpreting a number of types of tests.

Somatic cell nuclear transfer and transcription-factor-based reprogramming revert adult cells to an embryonic state, and yield pluripotent stem cells that can generate all tissues. Through different mechanisms and kinetics, these two reprogramming methods reset genomic methylation, an epigenetic modification of DNA that influences gene expression, leading us to hypothesize that the resulting pluripotent stem cells might have different properties. Here we observe that low-passage induced pluripotent stem cells (iPSCs) derived by factor-based reprogramming of adult murine tissues harbour residual DNA methylation signatures characteristic of their somatic tissue of origin, which favours their differentiation along lineages related to the donor cell, while restricting alternative cell fates. Such an 'epigenetic memory' of the donor tissue could be reset by differentiation and serial reprogramming, or by treatment of iPSCs with chromatin-modifying drugs. In contrast, the differentiation and methylation of nuclear-transfer-derived pluripotent stem cells were more similar to classical embryonic stem cells than were iPSCs. Our data indicate that nuclear transfer is more effective at establishing the ground state of pluripotency than factor-based reprogramming, which can leave an epigenetic memory of the tissue of origin that may influence efforts at directed differentiation for applications in disease modelling or treatment.
