Impact of natural light on growth and biopigment profile of cyanobacteria Spirulina platensis.

Cyanobacteria are economically important microorganisms and good source of natural pigments such as chlorophyll, carotenoids and phycobilliproteins. The present research work showed the optimum combination of photophase and scotophase of Spirulina platensis on biomass and chlorophyll-a, carotenoids, phycocyanin, allophycocyanin, and phycoerythrin contents. The study revealed that among all six light conditions tested, the cultures placed at west facing window, receiving natural day light at temperature 30°C showed extremely significant higher biomass (O.

Role of institutional climate in fostering diversity in biomedical research workforce: a case study.

This article reviews the barriers to diversity in biomedical research and describes the evolution of efforts to address climate issues to enhance the ability to attract, retain, and develop underrepresented minorities, whose underrepresentation is found both in science and medicine, in the graduate-school biomedical research doctoral programs (PhD and MD/PhD) at Mount Sinai School of Medicine. We also describe the potential beneficial impact of having a climate that supports diversity and inclusion in the biomedical research workforce. The Mount Sinai School of Medicine diversity-climate efforts are discussed as part of a comprehensive plan to increase diversity in all institutional programs: PhD, MD/PhD, and MD, and at the residency, postdoctoral fellow, and faculty levels.

Diversity in the biomedical research workforce: developing talent.

Much has been written about the need for and barriers to achievement of greater diversity in the biomedical workforce from the perspectives of gender, race, and ethnicity; this is not a new topic. These discussions often center around a "pipeline" metaphor that imagines students flowing through a series of experiences to eventually arrive at a science career. Here we argue that diversity will only be achieved if the primary focus is on (1) what is happening within the pipeline, not just counting individuals entering and leaving it; (2) de-emphasizing the achievement of academic milestones by typical ages; and (3) adopting approaches that most effectively develop talent.
