We got a sample of what I can only describe as "alien hamburger" from XEDRA-40 today.
They say the probe was being chased by some kind of enormous creature in 079XE.
It managed to get an appendage through the portal, but they shut it down and it was sliced off.
The bit of claw that remained on this side rapidly degraded to mush.
We haven't been able to ascertain exactly why, but Melchior helped us model molecular coherence with the physical laws applying in 079XE: this has yielded the working hypothesis that in 079XE, it is possible for nitrogen groups to form a stable durable bond akin to a disulfide bridge.
These bonds might have been critical to holding the thing together, and when the became less stable in our world, the creature collapsed.
