By repeatedly flipping how atoms push and pull on each other, physicists in Innsbruck say they created a 'fractional Fermi sea', an excited yet ordered state that breaks a standard theory. The experiment still awaits peer review.

In a randomized trial of 283 adults with type 2 diabetes not using insulin, wearing a continuous glucose monitor lowered HbA1c by 0.9 points more than routine care and added about five hours a day in the healthy range.
