Toward Eco-centric, Earth-as-School, and Love-based Curriculum and Learning: Example of a graduate course

This article puts forward love, care, and reverence for all people and our nonhuman kin as the center of posthumanist education. Opening our spiritual eye and building intimate relationships with nature and with all elements of the universe is envisioned as part of a schooling or post-schooling experience; our body, heart and spirit, along with our mind, is an essential part of learning. The article describes the experiences of students taking a graduate level course focusing on global climate change and education at a university in the United States. We use the course as an example to explore what posthumanist education entails. In this qualitative study, students taking the course, along with the faculty designing and teaching the course, describe the course curriculum and pedagogies and reflect on the course’s impact on them. Data sources include the syllabus, students’ reflection papers, nature contact journals, final projects, art works, and group conversations. Although situated in North America, the article is rich with international perspectives as student authors came from six different countries. The article posits that posthumanist education must be eco-centric and love-based, engaging students’ whole being to feel for and love Mother Nature. Keywords: curriculum, education, nature, posthumanism, climate change, higher education, teaching and learning, contemplative pedagogies, spirituality &nbsp

Ulcerative colitis-risk loci on chromosomes 1p36 and 12q15 found by genome-wide association study.

Ulcerative colitis is a chronic inflammatory disease of the colon that presents as diarrhea and gastrointestinal bleeding. We performed a genome-wide association study using DNA samples from 1,052 individuals with ulcerative colitis and preexisting data from 2,571 controls, all of European ancestry. In an analysis that controlled for gender and population structure, ulcerative colitis loci attaining genome-wide significance and subsequent replication in two independent populations were identified on chromosomes 1p36 (rs6426833, combined P = 5.1 x 10(-13), combined odds ratio OR = 0.73) and 12q15 (rs1558744, combined P = 2.5 x 10(-12), combined OR = 1.35). In addition, combined genome-wide significant evidence for association was found in a region spanning BTNL2 to HLA-DQB1 on chromosome 6p21 (rs2395185, combined P = 1.0 x 10(-16), combined OR = 0.66) and at the IL23R locus on chromosome 1p31 (rs11209026, combined P = 1.3 x 10(-8), combined OR = 0.56; rs10889677, combined P = 1.3 x 10(-8), combined OR = 1.29)

Measurements of polarized photo-pion production on longitudinally polarized HD and Implications for Convergence of the GDH Integral

We report new measurements of inclusive pion production from frozen-spin HD for polarized photon beams covering the Delta(1232) resonance. These provide data simultaneously on both H and D with nearly complete angular distributions of the spin-difference cross sections entering the Gerasimov-Drell-Hearn (GDH) sum rule. Recent results from Mainz and Bonn exceed the GDH prediction for the proton by 22 microbarns, suggesting as yet unmeasured high-energy components. Our pi0 data reveal a different angular dependence than assumed in Mainz analyses and integrate to a value that is 18 microbarns lower, suggesting a more rapid convergence. Our results for deuterium are somewhat lower than published data, considerably more precise and generally lower than available calculations.Comment: 4 pages, 4 figures.

Quantum Computing

Quantum mechanics---the theory describing the fundamental workings of nature---is famously counterintuitive: it predicts that a particle can be in two places at the same time, and that two remote particles can be inextricably and instantaneously linked. These predictions have been the topic of intense metaphysical debate ever since the theory's inception early last century. However, supreme predictive power combined with direct experimental observation of some of these unusual phenomena leave little doubt as to its fundamental correctness. In fact, without quantum mechanics we could not explain the workings of a laser, nor indeed how a fridge magnet operates. Over the last several decades quantum information science has emerged to seek answers to the question: can we gain some advantage by storing, transmitting and processing information encoded in systems that exhibit these unique quantum properties? Today it is understood that the answer is yes. Many research groups around the world are working towards one of the most ambitious goals humankind has ever embarked upon: a quantum computer that promises to exponentially improve computational power for particular tasks. A number of physical systems, spanning much of modern physics, are being developed for this task---ranging from single particles of light to superconducting circuits---and it is not yet clear which, if any, will ultimately prove successful. Here we describe the latest developments for each of the leading approaches and explain what the major challenges are for the future.Comment: 26 pages, 7 figures, 291 references.

Development of a Chromosomally Integrated Metabolite-Inducible Leu3p-α-IPM “Off-On” Gene Switch

Background: Present technology uses mostly chimeric proteins as regulators and hormones or antibiotics as signals to induce spatial and temporal gene expression. Methodology/Principal Findings: Here, we show that a chromosomally integrated yeast ‘Leu3p-a-IRM ’ system constitutes a ligand-inducible regulatory ‘‘off-on’ ’ genetic switch with an extensively dynamic action area. We find that Leu3p acts as an active transcriptional repressor in the absence and as an activator in the presence of a-isopropylmalate (a-IRM) in primary fibroblasts isolated from double transgenic mouse embryos bearing ubiquitously expressing Leu3p and a Leu3p regulated GFP reporter. In the absence of the branched amino acid biosynthetic pathway in animals, metabolically stable a-IPM presents an EC 50 equal to 0.8837 mM and fast ‘‘OFF-ON’ ’ kinetics (t 50ON = 43 min, t 50OFF = 2.18 h), it enters the cells via passive diffusion, while it is non-toxic to mammalian cells and to fertilized mouse eggs cultured ex vivo. Conclusions/Significance: Our results demonstrate that the ‘Leu3p-a-IRM ’ constitutes a simpler and safer system for inducible gene expression in biomedical applications

A Cell Culture–Derived Influenza Vaccine Provides Consistent Protection Against Infection and Reduces the Duration and Severity of Disease in Infected Individuals

A Vero cell culture–derived seasonal influenza vaccine provides consistently high levels of protection against cell culture–confirmed infection over a complete influenza season. Influenza symptoms are also less severe and of shorter duration in individuals who become infected despite vaccination
