The Fukushima battle to remove contaminated water, and related issues.

Not going so well...the battle to remove water, that is.  Appears they're starting to lose some ground (pun not intended).

Separately, an April 7 quake was stronger than what a Miyagi (Onagawa) nuclear plant was designed for.

Of course, design strength of buildings isn't typically based on the failure point of materials, but rather, on a safety limit that is slightly higher than that, which is to say, that one would not expect failure unless the stress was much greater than the design strength.

Nonetheless, this revelation should be making Japanese people nervous, considering these aftershocks will last for years, though they are supposed to dissipate over time.

No surprise either, that radiation in fish caught off Fukushima coast, far exceeds Japan's legal limits (25x higher).

And this talk about the situation under control at Fukushima?  TEPCO announced yesterday that the temperature at the #4 reactor has risen to 90 degrees Celsius.  That's higher than the 84 degrees Celsius on March 14th, the day a fire broke out at the reactor.  Doesn't seem like they've really got the situation under control.
