<jats:p>The crisis at the stricken Fukushima Daiichi nuclear power plant is far from over. Some 100,000 residents who were evacuated will not return home until the reactors are firmly under control.</jats:p>

<jats:p>High-tech analyses of Japan's March earthquake overturn long-held views of fault behavior and warn that another disaster may be looming.</jats:p>

<jats:p>Failing at quake prediction, seismologists tried making fuzzier forecasts, but Japan's megaquake is only the latest reminder of the method's shortcomings.</jats:p>

<jats:p>As cryptic manuscripts and centuries-old labware yield their secrets, scholars are coming to realize that medieval "chymists" were real scientists after all.</jats:p>

<jats:p> Su <jats:italic>et al</jats:italic> . claim guanine-cytosine (GC) content variation can largely explain the observed tyrosine frequency variation, independent of adaptive evolution of cell-signaling complexity. We found that GC content variation, in the absence of selection for amino acid changes, can only maximally account for 38% of the observed tyrosine frequency variation. We also uncovered other mechanisms acting to reduce tyrosine phosphorylation that further support our previous proposal. </jats:p>

<jats:p> Tan <jats:italic>et al</jats:italic> . (Reports, 25 September 2009, p. 1686) argued that loss of tyrosine residues from proteins in metazoans was driven by positive selection to remove potentially deleterious phosphorylation sites. We challenge this hypothesis, providing evidence that the high guanine-cytosine (GC) content of metazoan genomes was the primary driver in the loss of tyrosine residues. </jats:p>
