Hints of Structure Beyond the Visible Universe
from New Scientist
Colossal structures larger than the visible universe - forged during the period of cosmic inflation nearly 14 billion years ago - may be responsible for a strange pattern seen in the big bang's afterglow, says a team of cosmologists. If confirmed, the structures could provide precious information about the universe's earliest moments.
In the first instant after its birth, the universe is thought to have experienced a rapid growth spurt called inflation. During this period, space itself expanded faster than the speed of light.
Inflation solves some cosmological puzzles, such as why relic radiation from the big bang, released when the universe was less than 400,000 years old, is relatively uniform.

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.
