"Today, P J Miranda at the Federal Technological University of Paraná in Brazil and a couple of pals study the social network between characters in Homer’s ancient Greek poem, the Odyssey. Their conclusion is that this social network bears remarkable similarities to Facebook, Twitter and the like and that this may offer an important clue about the origin of this ancient story."

Ancient trading
"Joakim Wehlin of the University of Gothenburg and Gotland University has examined Bronze Age stone monuments that sit along Sweden’s Baltic Sea coasts. It had been thought that the monuments, which resemble stone ships, were used primarily as grave sites. Wehlin, however, thinks that they were used by maritime groups trading in metal objects. “It seems like the whole body was typically not buried in the ship, and some stone ships don’t even have graves in them. Instead, they sometimes show remains of other types of activities. So with the absence of the dead, the traces of the survivors tend to appear,” he explained. The monuments may have been used to mark ports, waterways leading inland, and potential meeting places." From http://www.archaeology.org/news/690-130322-sweden-stone-ships-bronze-age

Stone ship at Blomsholm
The stone ship at Blomsholm near Strömstad in Bohuslän measures more than 40 metres in length and consists of 49 large menhirs. The bow and stern are about 4 metres high. There are several other large megaliths in the area. According to http://en.wikipedia.org/wiki/Stone_ship
Lindholm Høje
"Lindholm Høje (Lindholm Hills, from the word for hill or mound) is a major Viking burial site and former settlement situated to the north of and overlooking the city of Aalborg in Denmark. The southern (lower) part of Lindholm Høje dates to 1000 – 1050 AD, the Viking Age, while the northern (higher) part is significantly earlier, dating back to the 5th century AD.[1] An unknown number of rocks were removed from the site over the centuries, many, for example, being broken up in the 19th century for use in building roads..."

Anundshög
Anundshög is a tumulus in Sweden. It has a diameter of 60 metres (200 ft) and is about 9 metres (30 ft) high, dated between the Bronze Age and the late Iron Age. A fireplace under it has been dated by radiocarbon dating to sometime between AD 210 and 540. Some historians have associated the mound with the legendary King Anund. http://en.wikipedia.org/wiki/Anundsh%C3%B6g
At the foot of the mound are 2 large stone ships placed end to end, 51 metres (167 ft) and 54 metres (177 ft) long. Two other stone ships are visible. The site was a thing-place and the ship settings may be associated with this function, according to Wikipedia.

Astrophile: Saturn's egg moon Methone is made of fluff - space - 17 May 2013 - New Scientist
"Out among Saturn's menagerie of moons, a shiny white egg rests in a nest of ice crystals.
Named Methone, this small, oval moon was seen in close-up for the first time last year by NASA's Cassini spacecraft. Methone is utterly unlike the other small balls of ice and rock that dot the solar system, which are deeply scarred by impacts. Instead it is smooth, with not a hill or pockmark in sight. Now astronomers may have a clue as to why: Methone is made of lightweight fluff."Astrophile: Saturn's egg moon Methone is made of fluff - space - 17 May 2013 - New Scientist

Assembly line
"The assembly line was invented 100 years ago. It’s time to invent the disassembly line", Steven Cherry is telling at http://spectrum.ieee.org/podcast/at-work/innovation/the-future-of-the-assembly-line

Deep Space Beacon
Pulsed gamma rays from the Vela pulsar from photons detected by Fermi's Large Area Telescope. The Vela pulsar is the brightest persistent source of gamma rays in the sky. The bluer colour in the latter part of the pulse indicates the presence of gamma rays with energies exceeding a billion electron volts (1 GeV). For comparison, visible light has energies between two and three electron volts. Red indicates gamma rays with energies less than 300 million electron volts (MeV); green, gamma rays between 300 MeV and 1 GeV; and blue shows gamma rays greater than 1 GeV. The image frame is 30 degrees across. The background, which shows diffuse gamma-ray emission from the Milky Way, is about 15 times brighter here than it actually is.
