Sunspots 538

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

Computing: Jotti is an on-line site that lets you submit a possibly dangerous file for checking. The site checks with several malware detection processes, and gives you a report.

Education: Wired asks if speed reading is really possible.

Difference Between is a web site that posts -- what else -- the difference between lots of things, such as Greek and regular yogurt, Oxycodone and Oxycontin, after and afterward and a lot more. Searchable.

Politics: National Public Radio discusses why Donald Trump appeals to some on the religious right, even though he doesn't have evangelical Christian credentials.

Science: Christianity Today (!) has a splendid display of photos of plankton, near-microscopic organisms that are suspended in the ocean in vast numbers, and in a great variety of species.

Wired tells us that scientists are learning a lot about individual brain cells by making them light-sensitive. Really.

Wired also reports on cochineal, a substance derived from scale insects, which is an important food coloring.

And Wired reports on the largest insects in the world. They live in New Zealand.
