Boil them, deep-freeze them, crush them, dry them out or blast them into space: tardigrades will survive it all and come back for more
Researchers developed a protocol to disrupt tardigrade gene functions by double-stranded RNA-mediated RNA interference (RNAi). They showed that targeting tardigrade homologs of essential developmental genes by RNAi produced embryonic lethality, whereas targeting green fluorescent protein did not.
The Goldtsein lab at the University of North Carolina at Chapel Hill is developing the water bear Hypsibius dujardini (hip-SIB-ee-us doo-zhar-DEE-nee) as a new model for studying evodevo as well as resistance to extremes.
A new tardigrade species was discovered by Roberto Buidetti from Italy's University of Modena and Reggio Emilia while visiting Victoria Island. They were found on lake-shore mosses within the Crater Cirque, a natural bowl hollowed out by ancient glaciers.
Laboratory tests have shown that tardigrades can endure both an utter vacuum and intense pressures more than five times as punishing as those in the deepest ocean. Even temperatures up to 300 degrees Fahrenheit and as low as -458 degrees F (just above absolute zero) won’t spell the creature's doom.
In 1933, the owner of a New York City speakeasy and three cronies embarked on a rather unoriginal scheme to make a quick couple grand: Take out three life insurance policies on the bar’s deepest alcoholic, Mike Malloy, then kill him.
