Ten Recent Advances in Evolution By Carl Zimmer Posted 10.26.09 NOVA To celebrate the 150th anniversary of the Origin of Species, here's a list—by no means exhaustive—of some of the biggest advances in evolutionary biology over the past decade. These advances include not just a better understanding of how this or that group of species first evolved, but insights into the evolutionary process itself. In some cases those insights would have given Darwin himself a pleasant jolt of surprise. Ten significant leaps forward in evolution research in the past decade, as chosen and described by noted science writer Carl Zimmer Enlarge Photo credit: (Earth) © NASA; (text) © WGBH Educational Foundation Darwin envisioned natural selection acting so slowly that its effects would be imperceptible in a human lifetime. If he were alive today, Darwin would be astonished at the pace and nature of discoveries being made in evolutionary biology, including the witnessing of evolution in action.

Cancer Resources A major component of cancer progression is the loss of normal controls on cell proliferation (disruption of normal cell cycle regulation and cell signaling), in addition to other changes involving angiogenesis, cell adhesion, invasion and metastasis.

educreations teacherswithapps Educreations Interactive Whiteboard, by Educreations, Inc, is an incredible, yes that’s right, INCREDIBLE app. This newly released app comes with the huge bonus of being FREE! We think this app has the edge needed to push education in the right direction and to begin modernizing teaching as we know it. Educreations is not the first app using the whiteboard concept, but it is the first one geared specifically for the classroom. Educreations Inc had the wherewithal to realize the need to add the option to use multiple pages for the same lesson; this is another feature that makes this app a standout. This revised Bloom’s Taxonomy pyramid shows classification of levels of intellectual behavior that is important in the learning process. It is obvious that the developers in this new start-up company spent much time and consideration while incorporating user-friendly features into this app.
