Moon’s mineral water and where are all the aliens?

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in laboratories on Earth exhibit remarkable properties, such as the ability to climb upward and escape airtight containers. The finding has important implications for understanding nuclear interactions in matter at the highest known densities. See article.
g Abodes - Bring a filter if you plan on drinking water from the Moon. Water ice recently discovered in dust at the bottom of a crater near the Moon's South Pole is accompanied by metallic elements like mercury, magnesium, calcium, and even a bit of silver. Now you can add sodium to the mix. See article.
g Life - A parasite and a virus may be teaming up in a way that increases the parasite's ability to harm humans, scientists say. See article.
g Intelligence - The portion of the brain responsible for visual reading doesn't require vision at all, according to a new study published online on Feb. 17 in Current Biology, a Cell Press publication. Brain imaging studies of blind people as they read words in Braille show activity in precisely the same part of the brain that lights up when sighted readers read. The findings challenge the textbook notion that the brain is divided up into regions that are specialized for processing information coming in via one sense or another, the researchers say. See article.
g Message - Book alert: In response to Enrico Fermi's famous 1950 question concerning the existence of advanced civilizations elsewhere, physicist Stephen Webb in “If the Universe Is Teeming with Aliens... Where Is Everybody? Fifty Solutions to Fermi's Paradox and the Problem of Extraterrestrial Life” critically examines 50 resolutions to explain the total absence of empirical evidence for probes, starships, and communications from extraterrestrials. He focuses on our Milky Way Galaxy, which to date has yielded no objects or signals that indicate the existence of alien beings with intelligence and technology. His comprehensive analysis covers topics ranging from the Drake equation and Dyson spheres to the panspermia hypothesis and anthropic arguments. Of special interest are the discussions on the DNA molecule, the origin of life on Earth, and the threats to organic evolution on this planet (including mass extinctions). Webb himself concludes that the "great silence" in nature probably results from humankind's being the only civilization now in this galaxy, if not in the entire universe. This richly informative and very engaging book is recommended for most academic and public library science collections. See article.
g Cosmicus - You need to keep your thoughts from wandering, if you drive using the new technology from the AutoNOMOS innovation labs of Freie Universität Berlin. The computer scientists have developed a system making it possible to steer a car with your thoughts. Using new commercially available sensors to measure brain waves - sensors for recording electroencephalograms - the scientists were able to distinguish the bioelectrical wave patterns for control commands such as "left," "right," "accelerate" or "brake" in a test subject.
