To his astonishment, as the ice containing the microbes thawed under a microscope, Hoover saw the rod-shaped
cells start swimming around--picking up where they'd left off 32,000 years ago.
In the case of dentin, long and narrow crystals of hydroxyapatite grow along rod-shaped
molecules of collagen, a particularly abundant structural protein in the body.
They get their nutrition by sending into the bone a tangle of green, rootlike coils containing rod-shaped
bacteria that break down the skeleton's complex organic compounds (SN: 7/31/04,p.
In a demonstration of the new material's capabilities, the researchers twisted a rod-shaped
sample into a spiral and exposed it to UV light, fixing the shape.
bacterium found in the intestines of people and many other animals, E.
For years, nanotechnologists have grown spherical and rod-shaped
crystals of semi-conductors only a few nanometers across.
residents of an animal cell provide the cell with energy, and each mituchondrion has its own DNA strand, which is distinct from the DNA in the chromosomes that dwell in the cell's nucleus.
Silica from the precursor molecules bound to the hydrocarbons and coated the entire DNA scaffolding, eventually forming a rod-shaped
silica structure about 1 micron long and tens of nanometers wide.
In the new sensing scheme, the lipids attach themselves to the rod-shaped
liquid crystal molecules, which lie perpendicular to the surface and appear dark.
organic molecule made of six thiophene units forms the basis for each type of material.
No one has been able to uniformly synthesize rod-shaped
polymers the size of viruses, says physicist Seth Fraden of Brandeis University in Waltham, Mass.
Hoiczyk and his colleagues counted about 250 nozzles encircling each blunt end of this rod-shaped
