Emmy Noether (1882 – 1935) was a German mathematician who made important contributions to abstract algebra. Described by Einstein as the most important woman in the history of mathematics, she proved Noether's first and second theorems, fundamental in mathematical physics. Noether's first theorem explains the connection between symmetry and conservation laws. She also developed theories of rings, fields, and algebras. Born to a Jewish family in Erlangen; her work in Germany, principally at Göttingen University came at a time when women were largely excluded from academia there. In 1933, Germany's Nazi government dismissed Jews from university positions, and Noether moved to the U.S., teaching at Bryn Mawr College and at the Institute for Advanced Study. Noether was generous with her ideas and is credited with several lines of research published by others, even in fields far removed from her main work, such as algebraic topology. (Full article...)

Sabella pavonina, commonly known as the peacock worm, is a species of marine polychaete worm in the family Sabellidae. It can be found along the coasts of western Europe and the Mediterranean Sea, in shallow, tidal waters with a bed of mud, sand or gravel. The worm is 10 to 25 centimetres (4 to 10 inches) in length, with its body divided into 100 to 600 small segments. The head has two fans of 8 to 45 feathery radioles arising from fleshy, semi-circular lobes. The body is mostly grey-green while the radioles are brown, red or purple with darker bands. This group of S. pavonina worms was photographed with a short-snouted seahorse in a protected marine natural area near Porto Cesareo, Italy.
