Decades of experiment records were also lost when rising water fried lab computers' circuitry.
Decades of experiments in rebuilding China's political and educational systems followed.
To the Editor: After decades of experiments using chimpanzees, researchers around the world have realized that this approach is not the answer.
Fusion — the process by which hydrogen bombs explode and stars shine — could potentially mine cheap, limitless energy from atomic nuclei, but after decades of experiments and numberless careers, it still doesn't work and still nobody quits.
Ms. Jones is working in two areas that classical music is, after decades of experiments, still getting accustomed to: the use of video and projection technology in live performance and the introduction of a visual element to instrumental concerts.
Despite huge demand, and even though the ingredients for success are clear after two decades of experiment, extending charters' successes to the other 96% will take a long time.
Meanwhile, decades of experiments in "phage therapy" — the use of phages in lieu of antibiotics to control infections — took place in Tbilisi, Georgia, behind the Iron Curtain and out of Western scientific sight, and were then more or less neglected when the Cold War came to an end.
Yellow warblers can also distinguish foreign eggs from their own, decades of experiments since the 1980s by the University of Manitoba's Dr. Spencer Sealy and his students have revealed.
More than 2 decades of experiments have indicated that in certain circumstances neurons in the motor cortex are active even when an animal isn't moving.
Most, however, hinder a molecule's ability to survive or reproduce, and decades of experiments and theoretical models show that in a simple chemical solution, these bad mutations would accumulate over time and inevitably snuff out reproduction.
