A New Look at Newton's Second Law Could Explain Away the Existence of
Dark Matter | Popular Science
"A team headed by Vitorio De Lorenci of the Federal University of
Itajubá, Brazi devised an experiment that could finally try to directly
test MOND. They discovered that certain points on a well-placed,
precisely-controlled spinning disc can cancel out the acceleration of
the Earth's rotation, its orbit around the sun, and the orbit of the sun
around the galaxy's center.

Canceling out all those interfering accelerations would allow for a
measuring device mounted on the disc's rim to work unimpeded. If
Newton's second law holds as usual, the device should not detect any
unusual force. But if MOND holds true, the device should feel a strange
kick."
