Physicists examine the gravitational pull between two tiny masses, and how fossil lampreys could shake-up the field of vertebrate evolution.
This week, researchers have captured the smallest measurement of gravity on record, by measuring the pull between two tiny gold spheres. This experiment opens the door for future experiments to investigate the fundamental forces of nature and the quantum nature of gravity.

The larval stage of lamprey growth has long been thought to resemble the kind of early animal that all vertebrates evolved from. However, new research looking at the fossils of lamprey species suggests that this popular hypothesis may be incorrect.
