CORONA Digital Atlas of the Middle East

From Wikipedia:


The Corona program was a series of American strategic reconnaissance satellites produced and operated by the Central Intelligence Agency Directorate of Science & Technology with substantial assistance from the U.S. Air Force.

The Corona satellites were used for photographic surveillance of the Soviet Union (USSR), the People's Republic of China, and other areas beginning in June 1959 and ending in May 1972.

The name of this program is sometimes seen as "CORONA", but its actual name "Corona" was a codeword, not an acronym.

The Corona program was officially classified top secret until 1992. 

On February 22, 1995, the photos taken by the Corona satellites... were declassified under an Executive Order signed by President Bill Clinton.

The further review by photo experts of the "obsolete broad-area film-return systems other than Corona" mandated by President Clinton's order led to the declassification in 2002 of the photos taken from the KH7 and KH-9 low-resolution cameras.

The declassified imagery has since been used by a team of scientists from the Australian National University to locate and explore ancient habitation sites, pottery factories, megalithic tombs, and Paleolithic archaeological remains in northern Syria.

Similarly, scientists at Harvard have used the imagery to identify prehistoric traveling routes in Mesopotamia.

The CORONA Digital Atlas of the Middle East Project hosts a large amount KH-4B imagery where users can view and download spatially corrected images [exemplar up top].


Fair warning: there goes the day.

Hair Ice


From Wikipedia:



Hair ice (also known as ice wool or frost beard) is a type of ice that forms on dead wood and takes the shape of fine, silky hair.


It is somewhat uncommon, and has been reported mostly at latitudes between 45–55 °N in broadleaf forests.


The meteorologist and discoverer of continental drift, Alfred Wegener, described hair ice on wet dead wood in 1918, assuming some specific fungi as the catalyst, a theory mostly confirmed by Gerhart Wagner and Christian Mätzler in 2005.

In 2015, the fungus Exidiopsis effusa was identified as key to the formation of hair ice.

Alarm Clock Rug



From the Wall Street Journal:


This battery-powered rug ensures that you actually get out of bed.

The Ruggie wakes you with blasts of sound between 90 and 120 decibels, comparable to the volume of a blender — to turn it off, you must stand with your full weight on its soft fleece surface for a preset time of up to 30 seconds.

Once you're up, it obligingly streams tunes from your smartphone to overcome your resentment and ingratiate itself with you again.
