Reconstructing the Biology of Extinct Species: A New Approach
A computer reconstruction of an adult female baboon skull from high-resolution x-ray computed tomography (CT) slices. The skull is rendered transparent to show the position of the three semicircular canals and cochlea of left inner ear filled in red. The enlargement of the canals and cochlea is five times the size of the canals shown in the skull. Each canal is approximately 5 mm in diameter. Credit: Alan Walker lab, Penn State

Gamma-Ray Bursts Active Longer than Previously Thought
The X-ray Telescope on NASA's Swift satellite captured the intensity of a bright X-flare from GRB 060714. The elongated blue and gray regions are an artifact of the image processing (left). After the flare, (right) the GRB's X-ray emission faded considerably, revealing a faint afterglow. Click image to enlarge. Credit: NASA / Swift / XRT Science Team.
