Unless I'm mistaken, scientists still have no definitive answer for the exact composition of the Earth's core, so I can't help but hold reservations for the accuracy of this experiment.
Of what value is this research? How does the strength of the core relate to more meaningful topics, like shifts in the earth's magnetic fields, or the periodic flipping of the North/South "polarity"?
Is there any long-term value to this work, or just something to do that's interesting to these two?
So what do the findings of this research mean for humanity?
Just because you don't see the relevance (or anyone necessarily, at this point) doesn't make this science less valuable. It's more information than we had before. Maybe it come in handy some day, or maybe it's just more we know.
"Of what value is this research?"
That's what they asked Ben Franklin while he was flying his kite. After all, everybody knew that electricity was just a toy and always would be.

> Earth's core is surprisingly weak
A really unscientific term "weak"? What does it mean? Weak in what way ... more plastic, softer, more viscous? Huh? If you are going to bother reporting on this why not have something to say that says something? If it is weak in some way - what does that mean to us?

This is a brief report about a Stanford press release. Who, what, how, why, and a short quote. It's a reminder of how physical science is done and that our neighbors are doing it. Theorists make the educated guesses and experimentalists figure out ways to make the measurement. These comments pose thoughtful questions and should encourage researchers to make their work more accessible. Many federal grants or contracts mandate that a certain small percentage goes to K-12 or public outreach.
I found the press release at Web Link
It's a bit more illuminating and has a link to their recent article in "nature" (full pdf available for a price).
CrescentParkAnon on the right track -- I think it's the shear stress required to cause plastic flow, kind of like yield strength where something bends so far that it won't spring all the way back; in this case where hexagonal close packed iron crystal begins to creep by lattice dislocation. The experiment apparently shows the iron deforms much more easily than expected, putting a new constraint on theoretical models of how the solid part of the earth core evolved.
Maybe it's important, maybe not. In most people's daily lives it doesn't really matter whether the world is round or flat. Traffic is bad regardless.
What about that movie "Armageddon"? Is there any research to support the findings from the movie?
@Joe, yes there is! The findings were that Bruckheimer et al could turn a $140 million budget investment into $554 million in worldwide box office receipts.
All I care about is my office decor. It is so lovely. I have the most beautiful interior in all of Palo Alto. Our clients love our decor. As for the core of our planet....it might be weak like our competition.
