A 'Methuselah Tree' and a Provocative Australian Fossil
A 2,000-year-old date palm seed found in the arid Dead Sea palace of King Herod perched atop Masada has sprouted and grown into a tree, researchers reported last week. It has become the oldest seed ever grown.
Elsewhere, researchers said that a 200-million-year-old Australian fossil suggests that dinosaurs roamed farther than previously believed across the prehistoric supercontinent of Gondwana. The fossil belonged to a two-legged meat-eater related to a giant, big-clawed carnivore from Argentina.
And before it was swallowed by the sea, the English town of Dunwich was an important medieval city. Last week a research team set sail to discover the secrets of this British Atlantis. They will use the latest acoustic imaging technology to reveal Dunwich in its prime.

PODCASTS: From Balloons to Space Stations: Studying Cosmic Rays
Cosmic rays have mysterious qualities about them that scientists continue to research in order to better understand their origins and composition. Dr. Eun-Suk Seo, a professor of physics at the University of Maryland, and her colleagues, fly enormous balloons as large as a football stadium and a volume of 40-million-cubic feet for extended periods over Antarctica to study particles coming from cosmic rays before they break up in the atmosphere.
