Three years ago, a University of Utah-led team discovered that an ultra-compact dwarf galaxy contained a supermassive black hole, then the smallest known galaxy to harbor such a giant black hole. The findings suggested that the dwarfs were likely tiny leftovers of larger galaxies that were stripped of their outer layers after colliding into other, […]

Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term colonization of Mars. A solution common to both groups is to release carbon dioxide gas trapped in the Martian surface to thicken the atmosphere […]

Living cells are capable of performing complex computations on the environmental signals they encounter. These computations can be continuous, or analogue, in nature — the way eyes adjust to gradual changes in the light levels. They can also be digital, involving simple on or off processes, such as a cell’s initiation of its own death. […]

A team of scientists led by researchers from the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology (SOEST) found the first direct evidence for the surface exposed water ice in permanently shaded regions (PSRs) of the Moon. “We found that the distribution of ice on the lunar surface is very […]
