Spinning cells attract across long distances

Scientists have known for a long time that small particles of matter, from the size of dust to sand grains, can exert influences on each other through electrical, magnetic, or chemical effects. Now, this team has found a new kind of long-range interaction between particles, in a liquid medium, that is based entirely on their motions. And these interactions should apply to any kind of particles that move, whether they be living cells or metal particles whirled by magnetic fields.

 

The discovery, which holds for both living and nonliving particles, is described in a paper by Alfredo Alexander-Katz, the Walter Henry Gale Associate Professor of Materials Science and Engineering at MIT, and his co-researchers, in the Proceedings of the National Academy of Sciences.

 

Is it possible some particles in space are affected by this phenomenon, either quantum or macroscopic?

The effect required inert particles of equivalent size and composition between the spinners. In a film of clear water with no other similar non-spinning particles, there was no effect, it says.
