Researchers demonstrate way to control tree height

...ich plants such as rice or wheat were created that directed less energy to height growth and more to development of stout stems and plentiful seed. In orchards, semi-dwarf fruit trees produce more fruit that is easier to harvest. The improvements in cereal yields have been credited with preventing the starvat...

3-D ultrasound scanner provides in-depth view of the brain

... member Srinivasan Mukundan of Duke Medical Center directed a needle into a particular region of the animal's brain, as is required in surgeries to drain cerebrospinal fluid and relieve pressure on the brain. In a second animal, the researchers made use of dyes to enhance ultrasound images of blood vessels in...

Surprising origin of cell's internal highways

...und that microtubules originating at the Golgi are directed toward the cell "front," or the leading edge, of motile cells. Since such an orientation is needed for directional migration, Kaverina hypothesizes that this subset of microtubules may influence cell motility by facilitating the transport of proteins...
