Researchers may have just solved a 300-year-old riddle.
As part of a study to determine the direction in which Earth’s core spins, scientists in the United Kingdom and Switzerland analyzed seismic readings from earthquakes from the past few decades.
But, instead of finding out whether the planet’s center rotates eastward or westward, the team discovered a surprising answer to the question that’s evaded scientists for centuries: It’s both.
“The link is simply explained in terms of equal and opposite action,” lead researcher Dr. Philip Livermore, of the University of Leeds, said in a released statement. “The magnetic field pushes eastwards on the inner core, causing it to spin faster than Earth, but it also pushes in the opposite direction in the liquid outer core, which creates a westward motion.”

If the idea that matter can be organized in a way that’s similar to binary code seems implausible, get ready for a shock: It can. An MIT team has created a milli-motein — a tiny device made of millimeter-sized components with a motorized design inspired by proteins. Milli-moteins can naturally fold themselves into almost any shape imaginable.
Researchers at MIT’s Center for Bits and Atoms have created milli-motein — a manifestation of raw digital data that could create transformable robots. However, instead of pop-culture robots that can transform into giant cars or airplanes, these could result in material changes that might one day transform the world.
