Reviewing the top physics stories of 2012 with Ian Durham; searching for time's arrow in the string multiverse; & looking for the fundamental building blocks of space and time.

Experiments testing the limits of wave-particle duality; connecting time's flow to the illusion of the enduring self; & Jim Al-Khalili on his new book "Paradox".

Photon experiments raise uncertainty about Heisenberg's Uncertainty Principle; the lowdown on FQXi's new $3 million Physics of Information grant round; casting the universe as a hologram to discover when time began; & art meets physics at the Jiggling Atoms exhibition.

Questioning the parallel beliefs of quantum many-worlds supremo Everett; history of the Higgs with it's co-inventor Gerry Guralnik; quantum computing rewritten; & faster than light cosmology with Joao Magueijo.

Taking particle physics to Ghana in our Higgs update; Julian Barbour explains why time does not exist, shapes are fundamental and the connection between consciousness and quantum gravity; and the psychology of mental time travel.

Gruber Prize for Cosmology goes to WMAP ; searching the sky for "cosmic textures"; predicting the end of civilization; and the quantum fuel for time travel.

Did the universe--the multiverse, the cyclic universe, & the "cosmic egg"--have a beginning?; tips for winning the FQXi essay contest; the quantum art of gravity & linguistics; sniffing out a quantum theory of smell; and we put *your* questions about string theory & sound to our physicists.

Splitting the electron into two quasiparticles, the orbiton and spinon; how the brain perceives time—and how to fool it; and a table-top test of quantum gravity.

A radical rethink of quantum mechanics suggests time can flow backwards; Frank Wilczek discusses not-so-speedy neutrinos; and string theory, religion and music collide in two physics operas.
