Novel salamander robot crawls its way up the evolutionary ladder
03-08-2007 · EurekAlert!A group of European researchers has developed a spinal cord model of the salamander and implemented it in a novel amphibious salamander-like robot. The robot changes its speed and gait in response to simple electrical signals, suggesting that the distributed neural system in the spinal cord holds the key to vertebrates’ complex locomotor capabilities.

- Which came first, the chicken genome or the egg genome?
10-08-2007 · EurekAlert!
Researchers have created the first evolutionary history of the duplications in the human genome that are partly responsible for both disease and recent genetic innovations. This work marks a significant step toward a better understanding of what genomic changes paved the way for modern humans, when these duplications occurred and what the associated costs are - in terms of susceptibility to disease-causing genetic mutations.

- Scientists look at those in evolutionary race who don’t make it 'out of the gate'
01-22-2008 · EurekAlert!
In the race of evolution, scientists until now have only looked at winners and losers. Now, they've come up with a way to look at the contenders who never made it out of the gate.It's the organisms that die early in life, before scientists can assess what they might bring to the reproduction game, and that have gone uncounted in the effort to quantify genetic fitness. This group has been dubbed the "invisible fraction."

- Diversity promotes cooperation among microbes
10-23-2006 · EurekAlert!
Understanding how cooperation evolves and is maintained represents one of evolutionary biology's thorniest problems. New research using the bacterium Pseudomonas fluorescens has identified a novel mechanism that thwarts the evolution of cheats and broadens our understanding of how cooperation might be maintained in nature and human societies.

- MGH researchers describe new way to identify, evolve novel enzymes
08-15-2007 · EurekAlert!
The creation of totally new enzymes can help improve the synthesis of chemicals and pharmaceuticals, devise new tools for molecular biology research, and develop new therapies. In the Aug. 16 issue of Nature, two Massachusetts General Hospital researchers describe a way of creating novel enzymes that, for the first time, does not require prior understanding of exactly how the enzymes work.

- 'Jekyll and Hyde' bacteria offer pest control clue
12-19-2007 · EurekAlert!
New research at the University of York has revealed so-called 'Jekyll and Hyde' bacteria, suggesting a novel way to control insect pests without using insecticides. Scientists in the University's Department of Biology studied the relationship between plant-dwelling insects and the bacteria that live in them -- and discovered an unexpected interaction.

- Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause
03-12-2007 · EurekAlert!
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when the Isthmus of Panama was formed. They concluded that extinctions resulting when one ocean became two were delayed by 2 million years.
