Maternal effects are defined by mutations that affect the next generation when they are maternally inherited. To date, most indepth studies of maternal effects in plants have attributed their origin to genomic imprinting that restricts expression to the maternal allele. The DNA glycosylase DEMETER (DME) removes methylated cytosine residues, causing transcriptional activation of the maternal all...

We propose a new theory to explain developmental aberrations in plant hybrids. In our theory, hybrid incompatibilities arise from imbalances in the mechanisms that cause male sterility in hermaphroditic plants. Mitochondria often cause male sterility by killing the tapetal tissue that nurtures pollen mother cells. Recent evidence suggests that mitochondria destroy the tapetum by triggering stan...

The past two decades have seen the growing importance of statistical thought in providing practical solutions to real-world problems. The engineer, the scientist, the medical researcher, the business and public policy-maker all want the statistician as a partner in the effort to address vexing issues of practical significance. At play are multiple levels of statistical expertise – that of the e...

Research has found that children possess a broad bias in favor of teleological--or purpose-based--explanations of natural phenomena. The current two experiments explored whether adults implicitly possess a similar bias. In Study 1, undergraduates judged a series of statements as "good" (i.e., correct) or "bad" (i.e., incorrect) explanations for why different phenomena occur. Judgments occurred ...

The New York City Clinical Data Research Network (NYC-CDRN), funded by the Patient-Centered Outcomes Research Institute (PCORI), brings together 22 organizations including seven independent health systems to enable patient-centered clinical research, support a national network, and facilitate learning healthcare systems. The NYC-CDRN includes a robust, collaborative governance and organizationa...

Human bone marrow is a fascinating and complex organ. Its major function is to produce and sustain normal haemopoiesis, and in a normal adult this entails the production of more than 10 cells/day. The marrow contains most of the multipotent haemopoietic stem cells, and provides an environment for these cells to diVerentiate into each of the well recognised peripheral blood cells (erythroctes, l...
