Motor transport in bio-nano systems

Molecular motors are nanoscale engines which move along very thin rod-like filaments and, in this way, drive the heavy traffic of molecular cargo within biological cells. Both motors and filaments can be isolated from the cells and used to construct biomimetic transport systems. In order ...

Researchers discover why melanoma is so malignant

...ther cancers, melanoma is born with its metastatic engines fully revved. "Other cancers need to learn how to spread, but not melanoma," says Whitehead Member Robert Weinberg, senior author of the paper that will be published September 4 in the early online edition of the journal Nature Genetics. "Now, for ...

Sequencing our seas

...hey're small, these tiny microbial species are the engines of the biosphere, and in large part drive the cycles of matter and energy in the sea," said DeLong. Microbes near the ocean surface, for example, had more genes devoted to taking in iron, a major element necessary for growth in that zone. Genomes fr...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

...lucose) using machines similar to the two types of engines in a hybrid car. One machine, the mitochondrion, is an organelle that breaks down the glucose-using oxygen and produces ATP. The other does the same thing - albeit less efficiently - without using oxygen in a process called glycolysis. Like the hy...

UNC scientists solve mystery of how largest cellular motor protein powers movement

... dynein puzzle is similar to figuring out how auto engines make cars move. “You have an engine up front that burns gas, but we didn’t know how the wheels are made to move.?
