Hunting for the elusive neutrino typically involves treks to Antarctica, the Mediterranean, and Lake Baikal. But a growing number of projects are looking for the most energetic neutrinos by aiming radio telescopes at the moon.

Astronomers have found a new way to search for high-energy cosmic rays, the most energetic particles in the universe, by scanning the face of the Moon.

"A researcher from The University of Western Ontario has helped solve a 37-year old space mystery using lunar images released yesterday by NASA and maps from his own atlas of the moon."

First full geological map of a non-earth object. Sign of things to come.

"Das stärkere Nuckeln sei ein Zeichen von erhöhter Aufmerksamkeit, erklären die Wissenschaftler. Der fremde Sprachlaut machte die Neugeborenen demnach hellhörig. Der Laut aus der Muttersprache erregte dagegen weniger Aufmerksamkeit, da ihn die Kleinen bereits im Mutterleib verinnerlicht hatten, so die Interpretation der Wissenschaftler. "Unsere Studie belegt also erstmals, dass Föten vor der Geburt die Laute der Mutter erfassen und bereits als Erfahrung abspeichern können", resümiert Co-Autorin Christine Moon von der Pacific Lutheran University in Tacoma, Washington. Patricia Kuhl (University of Washington, Seattle) et al.: Acta Paediatrica, doi:10.1111/apa.12098"

A site about the engineer's from Moldova, Leonid Popusoi's, inventions and discoveries in astronomy and physics. \nIt contains descriptions of his inventions, books and videos.

There's an old saying that describes the weather in Maine as "9 months of wintah, and 3 months of damn poor sleddin'." But even the hardiest Mainer would be challenged by the climate on Saturn's big moon Titan, where "wintah" lasts 7½ years, temperatures struggle to reach -290°F (-178°C), the ground is rock-hard water ice, and a mix of liquid methane and ethane rains from the sky.

With its expansive range and unprecedented potential for anonymity, (the Internet gives voice to our deepest urges and most uninhibited thoughts. Inspired by the wealth of unfettered expression available online, neuroscientists Ogi Ogas and Sai Gaddam, who met as Ph.D. candidates at Boston University, began plumbing a few chosen search engines (including Dogpile and AOL) to create the world's largest experiment in sexuality in 2009. Quietly tapping into a billion Web searches, they explored the private activities of more than 100 million men and women around the world. The result is the first large-scale scientific examination of human sexuality in more than half a century, since biologist Alfred Kinsey famously interviewed more than 18,000 middle-class Caucasians about their sexual behavior and published the Kinsey reports in 1948 and 1953. Building on the work of Kinsey, neuroscientists have long made the case that male and female sexuality exist on different planes. But like Kinsey himself, they have been hampered by the dubious reliability of self-reports of sexual behavior and preferences as well as by small sample sizes. That is where the Internet comes in. By accessing raw data from Web searches and employing the help of Alexa-a company that measures Web traffic and publishes a list of the million most popular sites in the world-Ogas and Gaddam shine a light on hidden desire, a quirky realm of lust, fetish, and kink that, like the far side of the moon, has barely been glimpsed. Here is a sampling of their fascinating results, selected from their book, A Billion Wicked Thoughts.

It's now official that water has been found on the moon, and scientists have long seen it on Mars as well. In fact, water is all over the solar system and the rest of the galaxy - and since water is key to life as we know it, these discoveries raise the hope that we are not in fact alone.

Future expeditions to the moons of Jupiter and MaRS

Birger's find. It would be nice to know exactly where the sites are - presumably in the Pilbara somewhere.

Future Mars outposts or colonies may seem more distant than ever with NASA's exploration plans in flux, but the rocket technology that could someday propel a human mission to the red planet in as little as 40 days may already exist. A company founded by former NASA astronaut Franklin Chang-Diaz has been developing a new rocket engine that draws upon electric power and magnetic fields to channel superheated plasma out the back. That stream of plasma generates steady, efficient thrust that uses low amounts of propellant and builds up speed over time. "People have known for a long time, even back in the '50s, that electric propulsion would be needed for serious exploration of Mars," said Tim Glover, director of development at the Ad Astra Rocket Company.
