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.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
