variation

To tackle this challenge, scientists are turning to vast radio telescope networks designed to map subtle variations in cosmic radio intensity.

"For me, you're picking a spinner in every side because the variation changes the tempo of the game," he said earlier this month.

Some of the variation is the result of relatively low food availability, requiring the clever creatures to figure out unique ways of finding and retrieving food.

Another variation was for two companies to buy products or services from each other: higher sales for both, but no profits for either.

Because chromosome compaction can also be influenced by a cell's size and shape, the researchers are now exploring how variations in those features affect the structure of the genome and in turn, gene regulation.
