Scientists uncover new clues to limb formation (AND LOSS) IN SOME SEA MAMMALS
Researchers from the Northeastern Ohio Universities College of Medicine have revealed the genetic basis behind one of the best-documented examples of evolutionary change in the fossil record: how whales lost their hind limbs
Super-sized cassava plants may help fight hunger in Africa
In a recent study, genetically modified cassava plants produced roots that were more than two-and-a-half times the size of normal cassava roots

Researchers create new proteins by recombinig the pieces of existing proteins
An ongoing challenge in biochemistry is getting a handle on protein folding-that is, the way that DNA sequences determine the unique structure and functions of proteins, which then act as "biology's workhorses".
How odors are sensed:a complex system clarified
Yale scientists have systematically plotted the responses of the entire Drosophila (fruit fly) olfactory system, providing the first multi-dimensional map of the range of odorants sensed and the regions of the brain that are stimulated
Biochemists discover bacteria's achilles' heel
Researchers at the University of California, San Diego have determined what factors turn on protein production in bacteria, a finding that provides new targets for the development of antibiotics
Chemist discovers secret behind nature's medicines
MIT scientists have just learned another lesson from nature. After years of wondering how organisms managed to create self-medications, such as anti-fungal agents, chemists have discovered the simple secret
Nature's strongest glue could be used as a medical adhesive
A bacterium that lives in rivers, streams and human aqueducts uses nature's strongest glue to stay in one place, according to new research by Indiana University Bloomington and Brown University scientists
Power in the blood
How can we build up the adult stem cells that build your blood? Bring up the subject of stem cells, and Stuart Orkin brings up Martians

Scientists strengthen case for life on Earth more than 3.8 billion years ago
Ten years ago, an international team of scientists reported evidence, in a controversial cover story in the journal Nature, that life on Earth began more than 3.8 billion years ago—400 million years earlier than previously thought. A UCLA professor who was not part of that team and two of the original authors report in late July that the evidence is stronger than ever

Cellulose fiber formation trached for the first time
Cellulose—a fibrous molecule found in all plants—is the most abundant biological material on Earth
Mapping the foundation of human development
: Embryonic stem cells may one day provide a means to treat disease, but according to two new reports, they are already revealing remarkable insights into the mysteries of human biology
Movement of chromosome in nucleus visualized
The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around
Unraveling the mysteries of poison
If you get bitten or stung by snakes, spiders, or scorpions, you could die. They release poison - toxins - into your body, and these attach to ion channels in cell membranes. Until now, scientists did not understand exactly how this happens
