...n search of coconuts, which they later are able to crack
open with their massive claws. These crabs are fully adapted to a life on land and will actually drown if submerged in water. The robber crab's transition from sea to land has been accomplished through numerous, and in many cases far-reaching, adapta...

Protein helps regulate the genes of embryonic stem cells
...e research. Researchers five decades ago worked to crack
the genetic code, the nucleic acid sequence of As, Cs, Gs and Ts making up the DNA of genes. Today, Magnuson's team is trying to unravel a different, newly appreciated mode of inheritance: epigenetics. "Epigenetic inheritance is heritable information...
Studying glial cells in the roundworm may provide insight into human brain diseases
...netics. "This is the first paper to take a serious crack
at glial cells in C. elegans. It shows that the worm really is a great system in which to study glial cells, because we are able to get the kind of answers that could help us understand how they are functioning in the human brain." The story began 3...
Scientists crack code for motor neuron wiring
... technical advance that enabled the researchers to crack
this code. Using these antibodies, Dasen and colleagues pinpointed the pattern of expression of each protein within the set of motor neurons that project to limb muscles. "Once we had these reagents, we were able to obtain the high resolution maps of...

Algae's protein 'tails' create motion and aid munching
...R.I. -- When single-celled organisms such as sperm crack
their whip-like appendages called flagella, the beating sets them in motion. But in certain colonies of green algae, flagella also boost nutrient uptake, according to surprising new research. In the early online edition of the Proceedings of the Nati...
