How animals repurpose genes to develop both limbs, eyes

The last common ancestor of cephalopods and vertebrates existed more than 500 million years ago. In fact, a squid is more closely related to a clam than it is a to a person. Even so, the two lineages independently evolved ...

Fingerprint patterns are linked to limb development genes

In the most comprehensive analysis to date, researchers found that the shapes of fingerprints—whether they are circular, wavy, or winding—are influenced by the genes responsible for limb development instead of skin patterning. ...

Scientists identify essential factors for limb formation

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), working in partnership with researchers at the Institut de Recherches Cliniques de Montréal (IRCM) in Canada, have identified Meis transcription ...

Gene enhancers important despite apparent redundancy

Every cell in the body has the same DNA and genes, so a cell's properties and functions are determined by which genes are turned on. That's why it is critical to understand enhancers, short sections of non-coding DNA that ...

Discovery of why emus are grounded takes flight

Researchers from Monash University's Biomedicine Discovery Institute have helped solve the mystery of how emus became flightless, identifying a gene involved in the development and evolution of bird wings.

John Nhial was barely a teenager when he was grabbed by a Sudanese guerrilla army and forced to become a child soldier. He was made to endure weeks of walking with so little food and water that some of his fellow captives ...

New signal involved in limb growth found in flies

Many of the secrets of life, such as terminal size and shape, have been uncovered in studies performed over a century involving animal models such as the fruit fly Drosophila melanogaster. Now, IRB Barcelona researchers headed ...
