Gravitational Aharanov-Bohm Effect
The eerie quantum Aharanov Bohm effect, in which a particle is influenced by a field, even when it does not directly feel a force, has been demonstrated for the first time for gravity. Physicist Mark Kasevich describes his experiment to Zeeya (extended interview).

About Time
A new FQXi review covers the physics and neuroscience of time. Science journalist Kate Becker talks to Zeeya about quantum and relativistic conceptions of time, the arrow of time, and how our brains process temporal notions.

Choices Curve Spacetime
Quantum gravity expert Giovanni Amelino Camelia is searching for hints that observers may be able to act on spacetime, not only by their physical properties, but also by their choices--as he explains to reporter Sophie Hebden.
