How would you do if someone spun you around every few seconds all day long? Marine algae repeatedly get tossed about in coastal surf, and they cope quite well. Researchers want to find out how. The latest set of experiments has revealed built-in machinery that helps these single-celled creatures thrive amid the turbulence.

The March 1998 Impact article"Cloning - What is It and Where is It Taking Us?" discussed the procedure of cloning by somatic cell transfer. In that procedure, the nucleus from a cell derived from an embryo, a fetus, or tissue of an adult is inserted into an egg from which the nucleus has been removed.

Researchers at the University of Aarhus in Denmark noticed something odd when they examined seafloor sediment that had been left for a few weeks in glass tubes—foul-smelling hydrogen sulfide had been removed from the top centimeter of the mud. This could not happen so quickly by oxygen passively diffusing down into the sediment, so they set out to find what was expediting the chemistry.

Nowadays, many folks (including some with leashed dogs) are taking walks in their neighborhoods, keeping six feet away from other walkers who are not family members (“social distancing”).
