Young women reported a mix of empowering and disempowering reasons for sending sexual images of themselves to others electronically.
The Hubble Space Telescope took this image of Abell 370, a galaxy cluster 4 billion light-years from Earth. Several hundred galaxies are tied together by gravity. The arcs of blue light are distorted images of galaxies far behind the cluster, too faint for Hubble to see directly. (Image: NASA, ESA, and J. Lotz and the HFF Team/STScI)

Engineering principles developed only 150 years ago were found to have evolved first in biological circuitry that controls cell growth, according to new UA research.
Astronomers think that the expansion of the universe is regulated by both the force of gravity, which acts to slow it down, and a mysterious dark energy, which pushes matter and space apart at faster and faster speeds. In this artist's conception, dark energy is represented by the purple grid above and gravity by the green grid below. Gravity emanates from all matter in the universe, even dark matter.
