Columns of white vapor streamed from the Atlantic this winter. About 8km west of an island called Terceira in the Azores, a submarine eruption was under way. Hot lava squeezed up through cracks in the ocean floor at about 500 meters below the surface of the ocean. The lava solidified into lava balloons. These gas-rich lava balloons interacted with cold seawater as they rose. This process generated steam, which emerged from the Atlantic like smoke from dozens of chimneys. The steam rose about 10 meters high. As the lava balloons reached the surface, the gas that made them buoyant escaped through cracks, and the balloons filled with water and sank.
You can keep the Sunday papers, I love to leisurely surf through the museum sites on my weekend mornings.
Here's another weird volcano I posted about some time ago.

The Andromeda galaxy is one of the Milky WayÂ’s nearest galactic neighbors.Astronomers recently found star clusters of a type never seen before orbiting Andromeda.
More familiar to scientists are globular clusters. These collections of stars are densely packed.
The newly discovered clusters are much larger and less dense than globular clusters.
These “extended clusters” are not found in the Milky Way. Why not is still unknown.
Mankind may never know it all, but we continue to learn.

Archaeologist finds 'oldest porn statue'.
Over 7,000 years old, depicting a man and woman practicing the world's oldest intramural sport. They even named the male half of the statue, which is described as an 8 centimeter lower half of a man.
"This is such an interesting discovery," said Dr Sträuble, "as these figurines are not stylistic, but realistic.
8 centimeters? That ain't realistic around here, bucko.

Most products of crossbreeding, such as the mule, are sterile. But the New Mexico Whiptail, as well as several other all-female species of whiptail lizard, does reproduce, and all of its offspring are female. Moreover, it reproduces by parthenogenesis -- its eggs require no fertilization, and its offspring are exact and complete genetic duplicates of the mother.
The article is short but interesting, and makes me wonder anew at the workings of Mother Nature. Here, she's obviously used natural selection to solve a common problem, by eliminating the wet spot.
