Tissue culture is defined as the propagation of plant and animal cells through the placement of small amounts of tissue in an artificial environment. Given the appropriate conditions, most kinds of plant and animal cells will live, even multiply and...

For a variety of purposes, plant cells, tissues, organs, and whole plants can be grown in labware containing a medium composed of defined molecules. Tissue culture media provide water, minerals, vitamins, hormones, carbon sources, and antibiotics...

Tissue culture involves growing cells (see CELL) taken from multicellular animals (rather than just cultivating single-celled animals) in vitro in the laboratory. While there is little to be gained from such studies of a psychological or behavioural...

Tissue culture is the growth of tissues and/or cells separate from the organism. This is typically facilitated via use of a liquid, semi-solid, or solid growth media, such as broth or agar. Tissue culture commonly refers to the culture of animal cells...

Adam Zaretsky once spent 48 hours playing Engelbert Humperdincks's "Greatest Hits" to a dish of E.coli bacteria to determine whether vibrations or sounds influenced bacterial growth. Watching the bacteria's antibiotic production increase, Zaretsky decided that perhaps even cells were annoyed by constant subjection to "loud,...

John Gallagher pinches a pod from the long-stemmed plant in the greenhouse next to his office, cracks it open and pops the BB-sized seeds into his mouth."They're not going to compete with peanuts, but they're good," said Gallagher, a University of Delaware researcher studying the...

When David Milarch first visited Northern California in 1968, he thought he would see avenues of coast redwoods 100 miles long. What he found instead was a "moonscape," he said. Nearly 40 years later, the Michigan arborist has returned to the region to realize his...
