A new giant was born recently in the coastal waters of Antarctica. A series of images captured from May through the beginning of this month by ESA`s Envisat satellite shows the subsequent duel between the new iceberg and another as it breaks free of the Ross Ice Shelf and tries to move north.
Christened C-19 by the US National Ice Centre in Maryland, the new iceberg measured 200 x 32 km, and about 200 m thick.
As seen in the accompanying animation of images acquired by Envisat’s Advanced Synthetic Aperture Radar (ASAR) from 3 May through 7 October, C-19 jostles for position with an older iceberg, B-15a, resting aground in shallow water off Ross Island. C-19 scrapes along the side of B-15a and, failing to move its firmly anchored adversary, finally heads off into open sea and an eventual demise in warmer waters.

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
