Researchers develop liquid form of DNA
...ermine what will happen if they make the molecules shorter or change their shape. They also would like to figure out how different DNA sequences can provide different electrical signals. That knowledge could enable them or others to create novel circuits capable of storing and moving electronic information.......al valve opening in rats receiving parvalbumin was shorter than in control rats. Parvalbumin restored normal cardiac relaxation rates in an experimental animal model with the same type of slow relaxation found in human heart failure. "This was a proof-of-principle, short-term study," Metzger says.

Because faster muscles are less economical, and because the muscles of smaller animals have to exert larger muscle forces relative to body ...Ancient origins found in arabidopsis genome

Unlike many previous designs, the Swedish-made microrobots can function in salty broths, blood, urine, cell-culture medium and other liquids, suggesting a host of biotechnology uses.
