It came from the sea: 'Monster' crabs evolve a bug's nose

...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...

BGSU biologist trying to crack microscopic code

... Bowling Green State University biologist wants to crack the communication code of proteins, especially the ones whose "talking" aids and abets disease. "Proteins interact; they 'talk' to each other," the associate professor says. "It's how they know what to do, and it's how most of the things that need ...

Scientists crack the genome of the parasite causing trichomoniasis

...edicine, the team of scientists took four years to crack the surprisingly large genome of the single-celled parasite Trichomonas vaginalis. They published the draft sequence of the parasite's genome in the Jan. 12, 2007, issue of the journal Science. "It is a nasty bug," says Dr. Carlton. For example, in...
