Strange Science: Dinosaurs and Dragons Despised in the West and revered in the East, dragons have a long history in human mythology. How did the myth start? No one knows the exact answer, but some myths may have been inspired by living reptiles, and some "dragon" bones probably belonged to animals long extinct — in some cases dinosaurs, in others, fossil mammals. Starting in the early 19th century, scientists began to find a new kind of monster, one that had gone extinct tens of millions of years before the first humans evolved.
Is big data radiology's answer for the future? The term big data has been around for decades — and it's become a buzzword across many industries in recent years. Although health care has been slow to catch on, compared to other areas of health care, medical imaging lags even farther behind in using data analytics to improve efficiency and drive value. But experts agree this has to change. Molecular Expressions Microscopy Primer: Interactive Java Tutorials - Virtual Microscopy: Magnification Interactive Java Tutorials Magnification Module This interactive Java tutorial explores the effect of increasing magnification (equivalent to changing microscope objectives) on the ability to resolve features in a sample.
Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. The Other Fly Room: J. T.

E-mail: email@example.com Profiles of microorganisms: the microbial world We should note a technical point about this tree: the comparison of ribosomal RNA gene sequences can show the possible relatedness of organisms, but other information is needed to provide the root of a tree. One of the principal modes of evolution is thought to involve gene duplication followed by divergence. The original gene retains its vital function, while the copy can change and ultimately can encode a new function. If these paralogous gene pairs can be identified by sequence similarity, then the original gene should be present in all organisms whereas the new version will be present only in the more recently derived organisms. The root for the tree in the diagram above was determined by using paralogous genes for translation elongation factors involved in synthesis of protein chains on the ribosomes. Domains and Kingdoms
How Do You Create A Culture Of Innovation? This is the third part in a series by Scott Anthony, author of The Little Black Book Of Innovation. It sounds so seductive: a “culture of innovation.” The three words immediately conjure up images of innovation savants like 3M, Pixar, Apple, and Google--the sorts of places where innovation isn’t an unnatural act, but part of the very fabric of a company. It seems a panacea to many companies that struggle with innovation. But what exactly is a culture of innovation, and how does a company build it? While culture is a complicated cocktail, four ingredients propel an organization forward: the right people, appropriate rewards and incentives, a common language, and leadership role-modeling.
