Sunspots 468

Things I have recently spotted that may be of interest to someone else:


Christianity: We are less religious than we used to be, and National Public Radio reports on a study that says that the Internet is partly to blame.

Computing: Gizmo's Freeware recommends SeriesGuide, an Android app that gives information about upcoming TV shows, and more.

USA Today reports that cheerful posts on Facebook affect others positively, and the effect is unexpectedly large.

Are you storing your files in the cloud? Be careful out there, says NPR.

Wired on how the stock market is rigged in favor of traders with lots of resources, and access to superfast information feeds, and on what one man is doing about this.

Health: Studying the genetics of the whooping cough (pertussis) germ has led to an understanding of how it became a dangerous disease, according to a report by National Public Radio.

Humor: (or something -- this is real) Wired reports on 21st century California gold miners, who are doing things the old-fashioned way.

Science: Wired reports on the Absurd Creature of the Week, in this case an axolotl, which can re-grow limbs, and never outgrows its larval gills. We may learn how we can regenerate lost body parts by studying these animals.

New Scientist reports that pregnant mice with damaged hearts (artificially damaged) may be helped to recover with the help of fetal-derived stem cells. Interesting.

Why do we have stock markets?

Wired has a most interesting piece, mostly about why stock traders want to trade at as close to light speed as possible, and how that's being accomplished, but the article also raises a fundamental question, and gives a disquieting answer:

"High-frequency trading raises an existential question for capitalism, one that most traders try to avoid confronting: Why do we have stock markets? . . . Trading increasingly is an end in itself, operating at a remove from the goods-and-services-producing part of the economy and taking a growing share of GDP . . ."

I'm not an economist, but I'd suggest a small tax on each stock/commodity/futures/whatever transaction.

Definitely worth a read.
