He has been writing some articles about:
Quantum Fluctuations and Their Energy
Naturalness
The Hierarchy Problem Although this one isn't particularly new, he posted it in 2011.
These are 3 of the biggest problems facing physicists. He gives a pretty good explanation of what the problem is in each case. He doesn't have good answers, there aren't any yet.
