The Driving Force of Biomimicry

April 22, 2013 11:38 am | by Cynthia Fox | Articles | Comments

It already has its own peer-reviewed journal, its own economic index and its own institute. As Earth Day dawns, it is clear the 15-year-old field of “biomimicry” is robust. Peer-reviewed articles have doubled every two to three years to some 3,000, and there has been a tenfold expansion in biomimicry over 12 years.

Scientists Decode DNA of ‘Living Fossil’ Fish

April 17, 2013 2:42 pm | by MALCOLM RITTER - AP Science Writer - Associated Press | News | Comments

The African coelacanth is closely related to the fish lineage that started to move toward a major evolutionary transformation, living on land.


Melanoma-prone Fish Get DNA Decoded

April 16, 2013 10:37 am | News | Comments

Scientists have decoded the genome of the platyfish, a cousin of the guppy and a popular choice for home aquariums. Among scientists, the fish are meticulously studied for their tendency to develop melanoma and for other attributes more common to mammals, like courting prospective mates and giving birth to live young.

190M-Year-Old Dino Bones Hold Development Clues

Bedbug-trapping Leaves May Lead to Pest Control

April 10, 2013 10:48 am | News | Comments

Inspired by a traditional Balkan bedbug remedy, researchers have documented how microscopic hairs on kidney bean leaves effectively stab and trap the biting insects, according to new research. Bedbugs have made a dramatic comeback in the U.S. in recent years, infesting everything from homes and hotels to schools, movie theaters and hospitals.

The neighborhood looks exceedingly normal: single-family homes and apartment buildings packed together, dogs barking from postage-stamp-size lawns, parents hustling down narrow sidewalks to fetch their children from school. But something with very dangerous potential lies below the surface.

Dilution Effect Linking Biodiversity, Disease Challenged

March 20, 2013 10:10 am | News | Comments

More than three quarters of new, emerging or re-emerging human diseases are caused by pathogens from animals, according to the World Health Organization. But a widely accepted theory of risk reduction for these pathogens– one of the most important ideas in disease ecology– is likely wrong, according to a new study.

High Cesium Level Found in Fish by Fukushima Plant
