Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor.

Researchers have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain's 'feel good' chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for reward.

Researchers have recently identified a DNA region known as VNTR2-1 that appears to drive the activity of the telomerase gene, which has been shown to prevent aging in certain types of cells. Knowing how the telomerase gene is regulated and activated and why it is only active in certain cell types could someday be the key to understanding how humans age and how to stop the spread of cancer.

Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date.

Researchers have found a low-cost way to solve one half of the water-splitting equation to produce hydrogen as clean energy -- using sunlight to efficiently split off oxygen molecules from water. The finding represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure.
