RETINOPATHY A MARKER FOR COGNITIVE DECLINE. “One thing noteworthy here: the vascular system is incredibly important. If I had to choose just a few rejuvenation therapies out of a much larger set then one I’d be tempted to go for is a complete rejuvenation of the vasculature. Aging blood vessels do not deliver enough nutrients. They also rupture, causing dead of neurons in the brain. The damaging effects are manifold.”

ILYA SOMIN ON the politics of The Hunger Games. “The series is subject to such widely disparate interpretations in part because Collins’ world-building is relatively weak. We don’t learn very much about the political and economic system of Panem, and some of what we do learn is internally inconsistent.”

MARK TAPSCOTT: Is lefty “grassroots activism” just one Potemkin Village after another?

That seems like the way to bet, especially after seeing how they astroturfed campaign finance “reform,” and then bragged about it. But they’ve got this going for them: “It helps when so many journalists covering American politics desperately want to believe these Potemkin villages are reality.”

Related thoughts from Ann Althouse. “That sounds like Ravi was found guilty because he couldn’t disprove a motivation that was inferred based on Clementi’s subjective perception. And yet the defense was deprived of much of the evidence of Clementi’s subjective state of mind.”

FARHAD MANJOO: It’s the battery, stupid: The looming 4G smartphone crisis.

Whatever other features it may have, a phone’s battery is its limiting factor. If the battery doesn’t work, nothing else does. This week J.D. Power and Associates put out its 2012 smartphone customer satisfaction survey, and the results bear this out. The study shows that battery life is one of the most important factors in determining whether people love or hate their phones. Owners of 4G phones were less happy with their devices’ batteries than owners of 3G phones, mainly because 4G phones don’t live as long as 3G ones. What’s more, among people with 4G phones, battery life was the deciding factor in whether or not you’d be willing to buy the same brand of phone again. If you give your phone a 10 out of 10 for battery life, you’re definitely buying that same phone next time. If you give it anything less, you’re going to look elsewhere for your next device.

That underlines a looming problem in the smartphone business, one that will haunt every manufacturer and may undermine the post-PC revolution over the next few years: Every year, everything about phones keeps getting better—except the battery.

AMERICA’S FASTEST-SHRINKING INDUSTRY: Newspapers.

CROSS-CULTURE: Chinese Fish For Meaning In U.S. Carp Rampage. “To understand why Chinese netizens have taken such an interest in the story, it’s absolutely essential to know that the most popular dinner-table fish in seafood-crazy China is carp, bar none. Thus, news of America’s carp problem doesn’t set off alarm — it makes Chinese mouths water. Add the fact that Chinese covet wild carp — an expensive treat compared to cheaper, more common farmed carp — and poetry ensues. . . . The dominant thread in the ongoing discussion is this: The Chinese people, and their voracious appetites, are the solution to America’s carp woes.”

Instead of an invasive-species problem, let’s think of it as a solution to the trade deficit! It’s just a bigger version of my lionfish solution.
