PLoS Biology : Publishing science, accelerating research A Peer-Reviewed, Open Access Journal Current Issue PLOS Biology is a peer-reviewed, open-access journal featuring research articles of exceptional significance in all areas of biological science, from molecules to ecosystems. Brief Answers to Cosmic Questions Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? Acrylic on Flesh Alexa Meade is a Washington D.C. artist who paints real people to look like a two-dimensional canvas.

Biomedical engineering Example of an approximately 40,000 probe spotted oligo microarray with enlarged inset to show detail. Biomedical engineering (BME) is the application of engineering principles and design concepts to medicine and biology for healthcare purposes (e.g. diagnostic or therapeutic). This field seeks to close the gap between engineering and medicine: It combines the design and problem solving skills of engineering with medical and biological sciences to advance healthcare treatment, including diagnosis, monitoring, and therapy. Biomedical engineering has only recently emerged as its own study, compared to many other engineering fields. Such an evolution is common as a new field transitions from being an interdisciplinary specialization among already-established fields, to being considered a field in itself.
www.lib.utexas.edu/thermodex/ Select PROPERTIES you are looking for: About ThermoDex | List of Titles Indexed | Finding Thermodynamic Infomation (Guide) | Library Catalog ThermoDex contains records for selected printed and web-based compilations of thermochemical and thermophysical data for chemical compounds and other substances. You can select one or more compound types and link them to one or more property terms, and ThermoDex will return a list of handbooks that could contain these data. Due to copyright and technical considerations, the actual data are not contained in ThermoDex. ThermoDex is based primarily on the holdings of the Mallet Chemistry Library at the University of Texas at Austin.
The BBC Teaches Kids About Rocks Rocks & Weathering is a great animated site produced by the BBC. The site using interactive animations to teach students all about rocks. The site illustrates and explains how sedimentary, igneous, and metamorphic rocks form. In each stage of the site, students can "create" rocks and "inspect" rocks with a virtual magnifying glass. Students "create" rocks by compacting sediment or by adding water to cool lava. High-Efficiency Photovoltaic Cells Developed The Micro- and Nanotechnology Research Group of the Universitat Politècnica de Catalunya (UPC) has produced silicon photovoltaic cells with a conversion efficiency of 20.5%, the highest level achieved in Spain using this material. This figure is comparable to results obtained by leading research groups in the field at the international level. The cells developed by the UPC researchers have surpassed the 15% barrier -- the average efficiency of the most common photovoltaic cells. Specifically, a conversion efficiency (of incident light to electric power) of 20.5% has been achieved, which means the energy produced per unit of area can be increased by one third. For example, thanks to the high efficiency of this new cell type, only 4.8 m² of photovoltaic panels would be needed to meet one family's annual energy needs (an average of about 4 kWh per day). This compares to an area of 6.5 m² for traditional cells.
Hands-on Activities for Teaching Biology to High School or Middle School Students by Drs. Ingrid Waldron and Jennifer Doherty, University of Pennsylvania The expression "hands-on, minds-on" summarizes the philosophy we have incorporated in these activities - namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts. Many of our activities are explicitly aligned with the Next Generation Science Standards, as indicated by (NGSS) in the descriptions below and the links to the right.
Defining life: the development of an artificial cell Last year’s artificial cell was created by J. Craig Venter and colleagues using a "top-down" approach: they replaced the genome of a bacterium, Mycoplasma genitallium, with a synthetic DNA sequence they designed to contain the minimum set of genes required for life. It was an amazing feat, but all of the machinery necessary to make the cell work was already present within the bacterial shell. They simply hijacked it with their synthetic genome. How to Grasp Size, Scale and Temperature with Three Giant Infographics Jun 10, 2010 Here are three fantastic inforgraphics that will blow your mind. While the visuals help explain the sheer size, depth and temperature of things on our planet and in our Universe. You might feel slightly less significant :) Relatively speaking…
