  Tree of life

A global evolutionary map reveals new insights into our last common ancestor

In 1870 the German scientist Ernst Haeckel mapped the evolutionary relationships of plants and animals in the first 'tree of life'. Since then scientists have continuously redrawn and expanded the tree adding microorganisms and using modern molecular data, yet, many parts of the tree have remained unclear. Now a group at the European Molecular Biology Laboratory [EMBL] in Heidelberg has developed a computational method that resolves many of the open questions and produced what is likely the most accurate tree ever. The study, which appears in the current issue of the journal Science, gives some intriguing insights into the origins of bacteria and the last common universal ancestor of all life on earth today.

  Knowledge and Information Visualization

Editors’ Note:
"Until now, knowledge visualization and information visualization investigated the question of visualization from different perspectives.
However, as there are some common areas of interest, synergy effects can be expected. In an international workshop titled “Visual Artefacts for the Organization of Information and Knowledge. Searching for Synergies” held in May 2004 at the Knowledge Media Research Center in Tuebingen (Germany), leading-edge researchers tackled the problem of looking for synergies.
This book explores the approaches of most of the workshop participants, as well as other invited experts. The intention of the book is to advance current research and development in the fields of knowledge and information visualization, to push the borders of what is now feasible and applicable to develop synergistic approaches that may represent both knowledge and information in a comprehensive manner."

  NewsMap

Newsmap is an application that visually reflects the constantly changing landscape of the Google News news aggregator. A treemap visualization algorithm helps display the enormous amount of information gathered by the aggregator. Treemaps are traditionally space-constrained visualizations of information.
 
  Buzztracker

The "Buzztracker" is a visualization of current world news. It visualizes frequencies and relationships between locations in the Google world news directory. You can view the most active areas of news in the world at a glance.

There is also a widget for mac here.

  Figurative system of human knowledge


"Systême Figuré des connoissances humaines"

A cartography of the "figurative system of human knowledge", sometimes known as the tree of Diderot and d'Alembert, was a tree developed to represent the structure of knowledge itself, produced for the Encyclopédie by Jean le Rond d'Alembert and Denis Diderot.

The tree was a taxonomy of human knowledge, inspired by Francis Bacon's Advancement of Knowledge. The three main branches of knowledge in the tree are: "Memory"/History, "Reason"/Philosophy, and "Imagination"/Poetry.

  Processes that pop out

New article from the digital magazine of InfoVis.net:

"One of the reasons why visualisation can be so powerful has its roots in the fact that there's a series of identification and recognition operations that our brain performs in an "automatic" way without the need to focus our attention or even be conscious of them. Managing properly the elements that are "pre-attentively" processed can make a difference in a user interface. "
