To STEM or not to STEM? That is not the question [PDF]
Cypriot Journal of Educational Sciences, 2018 The aim of this study is to identify the faults in Science, Technology, Engineering and Mathematics (STEM) education and to provide an approach to how these deficiencies can be eliminated. The STEM approach can provide students with an interdisciplinary point of view to gain creativity, critical thinking, high-level skills of thinking and problem ...

Stemming vision loss with stem cells [PDF]
Journal of Clinical Investigation, 2010 Dramatic advances in the field of stem cell research have raised the possibility of using these cells to treat a variety of diseases. The eye is an excellent target organ for such cell-based therapeutics due to its ready accessibility, the prevalence of vasculo- and neurodegenerative diseases affecting vision, and the availability of animal models to ...

Science, 2007 Two converging events took place on 9 August that ought to have the scientific community scratching its collective head. One of these is an anniversary: On that date in 2001, President George W. Bush signed an Executive Order banning any use of federal funds to support research on stem cells (save, of course, for those 78 preexisting cell lines, only ...

Stemness, cancer, and cancer stem cells [PDF]
Cell Cycle, 2008 The ability of cancers to grow indefinitely has fueled the idea that cancer and stem cells may have common underlying mechanisms. Detailed gene expression maps have now shown the diversity and distinctiveness in gene expression programs associated with stemness in embryonic and adult stem cells. These maps have further revealed a shared transcriptional

Cancer Cell, 2009 Despite great advances in our understanding of tumor initiation and progression, the identity of the "cell of origin" of cancer remains elusive. Two recent publications provide experimental evidence that normal intestinal stem cells are the cells of origin of intestinal cancer in the mouse.

Stemming on STEM: A STEM Education Framework for Students with Disabilities
Journal of Science Education for Students with Disabilities, 2016 There has been increased attention paid to science, technology, engineering, and mathematics also known as STEM. The focus on STEM has been both educational and occupational. Unfortunately, students with disabilities perform below their peers without disabilities in math and science.

Hematopoietic stem cell metabolism and stemness
Blood Science, 2019 AbstractHematopoietic stem cells (HSCs) are considered to originate from the aorta-gonad-mesonephros, migrate into fetal liver for a rapid expansion, and eventually reside into a unique hypoxic bone marrow niche, where they maintain their homeostasis throughout their life span.

Cells, Stem Cells, and Cancer Stem Cells [PDF]
Seminars in Reproductive Medicine, 2013 The stem cell field owes a great deal to the previous work conducted by embryologists and researchers devoted to reproductive medicine. The time is coming when this emerging field will pay off in the reproductive sciences by offering new avenues of understanding gametogenesis and early embryonic development.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...
