not sure what area we are looking at as it is zoomed in so close - is there something that has come loose to the left (circled in yellow)??
That's the radiator that is loose. The camera view is on the back of what looks like the S1 Truss

From ISS On-Orbit Status Report for 05/06/2010:

Following up on the earlier detection of metal shavings in the new MRM-1, CDR Skvortsov was to perform an inspection of the MRM-1 hatch screen, taking photographs for subsequent downlink and cleaning the screen with the vacuum cleaner if shavings or foreign materials were found.

SM Reboost Update:
As per plan, a one-burn ISS reboost was conducted this morning at 3:20 AM GMT using the SM’s two main engines. Performance was nominal. Burn duration: 4 min 7 sec; delta-V: 4.5 m/s/14.76 ft/s (predicted 4.36 m/s/14.30 ft/s). Mean altitude gain: 7.79 km/4.21 nmi (predicted 7.55 km/4.07 nmi). Purpose: set up orbital phasing for both Soyuz TMA-19/23S & Progress M-06M/38P launch/dock conditions.

Progress Reboosts:
Two more reboost maneuvers, one orbit apart, will be conducted by Progress M-05M/37P to fine-tune phasing for both Soyuz TMA-19/23S & Progress M-06M/38P launch conditions.
Reboost 1: TIG (Time of Ignition) = 11:55 PM GMT Mon. 07/06; burn duration: 9m 40s; delta-V: 0.8 m/s.
Reboost 2: TIG = 1:26 AM GMT Tue. 08/06; burn duration: 7m 15s; delta-V: 0.6 m/s.
Mean altitude increase after both burns: 2.55 km/1.38 nmi.

From ISS On-Orbit Status Report for 08/06/2010:

In the new MRM-1, with BITS2-12, VD-SU control mode and power supplies turned off, CDR Skvortsov uninstalled and removed electronics equipment (ABU SSVP, BUP-2, TA082/BNU) of the automatic control system used by MRM-1 during the approach & docking phase.

Reboosts Update:
Two single-burn reboost maneuvers were performed successfully this morning as scheduled, executed by the four Progress M-05M/37P mid-ring thrusters, one orbit apart, to fine-tune orbital phasing for both Soyuz TMA-19/23S & Progress M-06M/38P launch conditions.
. Reboost 1: TIG – 12:10 AM GMT; burn duration: 9m 40s.
. Reboost 2: TIG – 1:45 AM GMT; burn duration: 7m 15s.
. Total delta-V: 1.42 m/s (4.66 ft/s) [predicted: 1.4 m/s (4.6 ft/s)].
. Mean altitude increase after both burns: 2.45 km (1.32 nmi) [predicted: 2.41 km (1.30 nmi)].

From ISS On-Orbit Status Report for 09/06/2010:

CDR Skvortsov & FE-3 Kornienko continued their tear-down work in the new MRM-1, uninstalling & removing no longer needed electronic equipment. [Today the focus was on two boxes (TA082 & UDPK-24) of the BNU signal conditioning subsystem of the SBI onboard measurement system (discarded in Progress M-05M/37P), and the KL-108M-M transmitter of the Klest television system (temporarily stowed in MRM-1).]

Later in the day, Kornienko outfitted MRM-1 with an air duct (VD, vozduchovodiy), installing it with its adapter on the moduleís BVN air heater fan.

FE-2 Caldwell-Dyson had about 2 hours set aside for troubleshooting the OGS (Oxygen Generator System) delta-pressure sensor, and her labors proved to be successful. [In Part 1 of the procedure, FE-2 removed the degraded recirculation pump ORU and installed a new pump ORU for an electrical verification of the new pressure sensor by MCC-Houston. Since the new sensor indicated a healthy recirculation loop pressure (i.e., negligible dP), Tracy completed the installation of the new ORU as per plan. If the recirculation loop pressure had remained bad with the new sensor, the original ORU would have been re-installed.]

From ISS On-Orbit Status Report for 10/06/2010:

All three crewmembers performed the mandatory 60 minute New Module Delta Emergency Procedure drill, intended to familiarize the station residents with changes associated with the arrival of a new module (MRM-1) to be conducted no later than 7-10 days after arrival of the new module.

IWIS Thruster Firing:
With the protective shutters of the Lab, JPM & Cupola windows closed earlier by Caldwell Dyson, the US SAs (Solar Arrays) maneuvered to SARJ park position and feathered, and the station in TEA (Torque Equilibrium Attitude), a ground-controlled SM thruster firing test performed the SA 4A DTF (Dedicated Thruster Firing) for IWIS (Internal Wireless Instrumentation System) structural dynamics measurements during the firings for the current ISS configuration. [To obtain quiescence for the Solar Arrays, the station went into free drift at 2:00 PM GMT for 200 sec, followed by the 5 thruster firings from 2:03 PM-2:16 PM GMT, followed by another 200 sec of free drift. Attitude control authority returned to US Momentum Management at 2:55 PM GMT after ISS had maneuvered back to duty attitude. The goal of these periodic DTOs (Detailed Test Objectives) is not to excite the Arrays by direct plume impingement like in tests in the past but to excite the Arrays from their base via mechanical loads. The on-orbit data will be utilized to correlate math models utilized by structures & mechanism specialists.]

From ISS On-Orbit Status Report for 11/06/2010:

FE-2 Caldwell-Dyson supported ground-commanded troubleshooting of the OGS (Oxygen Generation System) by double-checking & photographing the electrical connections (W308-P23, W310-P24) of the newly installed OGS Pump ORU. [After the Pump R&R on 09/06, the Pump yesterday failed to spin up upon activation. Tracy’s inspection today was to rule out the Pump connectors as culprits. The OGA (Oxygen Generation Assembly) is currently not working].

From ISS On-Orbit Status Report for 12/06/2010:

Elektron Failure:
The Russian Elektron O2 generator failed unexpectedly last night at 9:44 PM GMT (under investigation). With a current ppO2 (partial pressure O2) of 159.75 mmHg, nominal crew metabolic rates (1.77 mmHg/day ppO2 decay for 3 persons) and ISS volume of 820 cubic meter (28,959 cubic feet), ppO2 would be at 148.9 mmHg at Soyuz TMA-19/23S hatch opening (minimum flight rule limit = 146 mmHg). After Soyuz TMA-19/23S hatch opening, the 146 mmHg limit would be reached after another ~19 hours (18/06 @ 9:00 PM GMT). Besides stored oxygen, there is also a large supply of SFOG on board (Russian: TGK).

From ISS On-Orbit Status Report for 13/06/2010:

In Node 3, FE-2 Caldwell-Dyson prepared the OGS (Oxygen Generator System) in the ARS (Atmosphere Revitalization System) rack for tomorrow’s planned R&R of the recirculation pump ORU, opening the ARS's right access door to allow for 24 hour thermal equalization, and disconnecting the O2 outlet hose from the N2 purge ORU. [The decision has been made to re-install the original (degraded) pump in the OGS since the temporary replacement of the pump with a spare did not fix the OGS problem.]

Elektron Update:
After its overnight failure on 11-12/06, the Russian Elektron oxygen generator was successfully reactivated by TsUP-Moscow and the crew yesterday morning and restored to service.

From ISS On-Orbit Status Report for 15/06/2010:

FE-3 Mikhail Kornienko had 2.5 hours set aside to continue cargo removal & transfers from the new MRM-1. [This involved removing interior panels (302, 304, 306, 102, 104, 107), unscrewing tie-down bolts, cutting cargo straps, detaching storage frames and retrieving 7 Russian & 9 US cargo bags from the frames for stowage in MRM-1 or handover to Caldwell-Dyson for stowage in the USOS.]

OGS Pump ORU Update:
The R&R of the OGS (Oxygen Generation System) water recirculation pump in the ARS (Atmosphere Revitalisation System) rack reported yesterday had to be deferred since the necessary equalization of cabin temperature with the OGS temperature had not been accomplished. The R&R has been re-scheduled for tomorrow.

Elektron Shutdown Update:
The automatic shutdown of the Russian Elektron O2 generator on 11/06 evening was commanded by the controlling software due to a high temperature reading from the KOB-1 internal thermal control loop. After TsUP-Moscow switched the Elektron to KOB-2, the system returned to nominal function in 32 Amp mode.

Vozdukh Test Update:
For today and tomorrow, the Vozdukh CO2 (Carbon Dioxide) scrubber is being assessed by ground specialists for its efficiency in removing CO2 from the ISS atmosphere. The US CDRA will remain deactivated for the duration of the test and will be reactivated either tomorrow (16/06) or if CO2 levels reach flight rule limits or the crew reports symptoms.

From ISS On-Orbit Status Report for 16/06/2010:

FE-2 Tracy Caldwell-Dyson successfully re-installed the old OGA (Oxygen Generation Assembly) water recirculation pump ORU in the ARS (Atmosphere Revitalisation System) rack. [OGA will be activated on Friday (18/06). Since the dP (delta-Pressure) sensor remains failed, ground teams are working to ensure that all software inhibits are in place to operate with sensor inhibited.]

Spending several hours in the new MRM-1, FE-3 Mikhail Kornienko continued tearing down no longer needed electronic equipment, today uninstalling & removing two Power Switching Units (BSK-1V, BSK-5B), a BSK-5B switch for the high-gain antenna, and a KSR Matching Resistor Switching Unit. Also planned was the removal of two SNT-50 boxes with their cables, but this task was deferred to a later date. [The removed equipment was required only for the flight, approach & docking phases of MRM-1. With the module now permanently linked to ISS at the FGB Nadir port, the equipment can be recycled and the volume taken up by it in the module freed for other uses.]

Oxygen Supplies Update:
Without OGA but with Elektron running, there is enough O2 in the cabin atmosphere of the ISS to support a six-person crew until late next week. There are sufficient quantities on board to support the full crew through September before reaching the "reserve" line without resupply. With the arrival of Progress M-06M/38P, an additional month would be gained.

Vozdukh Capacity Test Update:
While ISS has a three-person crew, engineers are using the opportunity to test the Vozdukh CO2 (Carbon Dioxide) removal system by not operating the US CDRA. After almost 72 hours without CDRA, CO2 level is at 5.5 mm Hg as measured by the dependable MCA (Major Constituent Analyzer). The crew has experienced no symptoms. CDRA will be activated again this afternoon to drive CO2 levels down again prior to tomorrow's docking.

I don't understand what is written here. KOBs loops are part of STR (thermal regulation), what is the link with Elektron ?

I think Elektron was shut down either because it got too hot, or because it was introducing too much heat into the overloaded KOB-1 loop.
