Sunspots 300

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

Science: The DNA of the water flea, Daphnia, has been sequenced, according to a report on NPR.

That marcescence is the term applied to deciduous trees that do not shed their leaves in the fall, such as the beech.

Politics: Wired discusses attempts to count large gatherings, like those in Cairo. They say that Tahrir Square will only hold about 225,000 people.

(or something) A newly discovered Brazilian tribe has probably had no contact with "civilized" people, ever. Wired shows photos, taken from the air. There are perhaps 100 such tribes around the world.

Computing:  Gizmo's Freeware reports on Prey, a free program, running on Windows, Mac, and Android, that allows you to order a missing smart phone to send you a map of where it is, and/or take photos showing its surroundings.
