The recent marriage of evolutionary biology with developmental biology has resulted in the birth of a new field, evolutionary developmental biology, or "evo-devo." Evo-devo scientists study the mechanisms that produce evolutionary changes in body plans over time. As one of the fields creators, Indiana University Bloomington biologist Rudolf Raff brings new understanding to the evolution of humans and other organisms by uniting fossil data and information about the genes that control development.
Major historical questions about the origin of multicellular animals, the Cambrian radiation and the origins of animal larvae can now be addressed using evo-devos mechanistic tools. Last month, the National Academy of Sciences chose Raff as the winner of its 2003 Elliott Medal for his role in founding evo-devo. Raff and IUB colleagues Loren Rieseberg, Thomas Kaufman, Michael Lynch and Jeffrey Palmer lead the largest concentration of evo-devo biologists in the nation.
In a presentation at the meeting of the American Association for the Advancement of Science titled "The Quick and the Dead: Developmental Genetics Meets Extinct Organisms," Raff will discuss how evo-devo will expand our understanding of the fossil record. He will show how and why some complex features in animal development may have evolved much more quickly than expected.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...
Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
