I am in Atlanta. Mizuno called me from the ACS conference in Salt
Lake City to say hello. He is going to present this afternoon.
He says there are many people attending the sessions, including young
people. He says Kitamura et al. independently replicated Arata, and
will report on his findings today. They used better calorimetry than
Arata did. The abstract is here:

We have started a series of deuterium (and hydrogen) gas charging
experiments with Pd nano-powders to study possible heat evolution and
D (or H)-loading characteristics by using a revised Arata-type twin
system. The twin system is made of identically designed A1 and A2
systems, in each of which an inner gas-charging cell with flow
calorimeter and an outer vacuum chamber are set up. The A1 system is
used for D-gas foreground run, and the A2 system is for the H-gas
blank run. Our first data with two commercially available Pd powders
(0.1 micron Pd particles and Pd-black) are already meaningful.
Experiments with Pd-black sample gave 2.6 kJ/g-Pd excess heat for the
second phase of 1,300 minutes operation and D/Pd=0.85 for the first
phase (about 100 min interval from start) with zero D-gas pressure.
No excess heat with H-gas charging was seen with H/Pd=0.78.
Experiments with 0.1 micron Pd powders gave D/Pd =0.45 for the first
phase and much less excess heat for the second phase. We are
extending experiments for nano-fabricated Pd samples to be reported
at the meeting. In situ radiation monitors are for neutron and
gamma-ray. Elemental analysis of "before/after" samples is done by
PIXE. He detection will be also tried.
Here is a recent paper from this group about an Iwamura replication:
