Submission + - Royal Navy Successfully Tests Quantum-Sensing Technology (royalnavy.mod.uk)

An anonymous reader writes: The Royal Navy has successfully demonstrated the capabilities of ground-breaking cold atom technology. P2000 vessel HMS Pursuer hosted the trial, which unlocks new possibilities in areas such as covert monitoring, which require precise signals for accurate positioning, navigation and timing. The Office of the Chief of Technology Officer (OCTO) for the RN worked with UK quantum technology company Aquark Technologies.

The trial involved the company’s miniature cold atom systems, founded on Aquark’s unique laser-cooling method, known as supemolasses. This method to generate cold atoms does not need an applied magnetic field, therefore reducing the size, weight, power consumption and cost of sensors. A cold atom is an atom that has been laser-cooled to extremely low temperatures, typically near absolute zero (-273.15C). At these temperatures, the thermal motion of atoms is very slow, allowing their quantum mechanical properties to be precisely controlled. Quantum Sensing is an advanced sensor technology that detects changes in motion, and electric and magnetic fields, by collecting data at the atomic level.

New Moon Found Orbiting Neptune 120

Dave Knott writes "A tiny, previously unknown moon circling Neptune has been spotted by astronomers using the Hubble telescope. The moon, which is currently known as S/2004 N1, was found on July 1 by Mark Showalter of the SETI Institute in Mountain View, Calif., NASA announced Monday. It is less than 20 kilometres wide and its orbit is 105,000 kilometres from Neptune, between those of Larissa and Proteus, two of Neptune's other 14 known moons. It circles Neptune once every 23 hours."

Journal Journal: Slashdot engineering status

I have been reviewing (again) the responses from our last user poll about what you like/dislike about /.. In summary it looks like there is a concern about commenting and story submission. We have spent the last couple of months working on those items and I think the engineering team has done a good job of fixing some problems that have been plaguing the system for some time (new comment loading, submission form, cleanup layout, etc., see:

Russian Websites Critical of Elections Targeted In DDoS Attack 156

theshowmecanuck submits this news from Russia, where "Websites which exposed violations in Russia's parliamentary elections were inaccessible Sunday in a hacking attack they said was aimed at preventing them revealing the extent of election day fraud." Further, says the linked article, "Prime Minister Vladimir Putin, whose United Russia party is expected to win Sunday's polls but with a reduced majority, has denounced non-governmental organisations like Golos, comparing them to the disciple Judas who betrayed Jesus. Russia has seen an upsurge in Internet penetration since the last elections in 2007, and analysts have said the explosion of critical material on the web poses one of the biggest challenges to United Russia's grip on power."

Chrome Becoming World's Second Most Popular Web Browser 511

redletterdave writes with news that Google Chrome is in the process of surpassing Firefox to become the second most popular web browser. Pinpointing the exact time of the change is difficult, of course, since different analytics firms collect slightly different data. The current crop of media reports were triggered by data from StatCounter, which shows Chrome at 25.69% and Firefox at 25.23% for November. Data from Net Applications shows Firefox still holding a 4% lead, but the trends suggest it will evaporate within a few months.

Submission + - Why Silicon-Based Aliens Would Rather Eat our Citi (universetoday.com)

Nancy_A writes: "While the world as we know it runs on Carbon, science fiction’s long flirtation with Silicon-based life — “It’s life, but not as we know it” — has become a familiar catchphrase.

Although non-Carbon based life is a very long shot, this Q&A with one of the US's top astrochemists — Max Bernstein, the Research Lead of the Science Mission Directorate at NASA headquarters in Washington,D.C. discusses what silicon life might be like."
