Is Quantum Theory About Reality or What We Know?
Does the quantum state ultimately represent some objective aspect of reality, or is it a way of characterizing something about us, namely, something about what some person knows about reality? By James Owen Weatherall.

Can Many-Worlds Theory Rescue Us From Boltzmann Brains?
Boltzmann’s theory leads to a paradox, where the very scientific assumption that we can trust what we observe leads to the conclusion that we can’t trust what we observe. By Brian Koberlein.

Violations of energy conservation in the early universe may explain dark energy
Physicists have proposed that violations of energy conservation in the early universe, as predicted by certain modified theories of quantum mechanics and quantum gravity, may explain the cosmological constant problem, which is sometimes referred to as “the worst theoretical prediction in the history of physics.” By Lisa Zyga.

Verlinde's new theory of gravity passes first test
A team led by astronomer Margot Brouwer has tested the new theory of theoretical physicist Erik Verlindefor the first time through the lensing effect of gravity. Brouwer and her team measured the distribution of gravity around more than 33,000 galaxies to put Verlinde’s prediction to the test. She concludes that Verlinde’s theory agrees well with the measured gravity distribution.

Scientists present the most accurate time measurements of quantum jumps to date
When a quantum system changes its state, this is called a quantum jump. Usually, these quantum jumps are considered to be instantaneous. Now, new methods for high-precision measurements allow us to study the time evolution of these quantum jumps. On a time scale of attoseconds, their time structure becomes visible. It is the most accurate time measurement of quantum jumps to date.
