Hubble's Exoplanet Pics Outshined by Keck's 140

Posted by timothy from the keckkeckkeck-is-the-new-bwahaha dept.
dtolman writes "Scientists at the Keck and Gemini telescopes stole the thunder of Hubble scientists announcing the first picture of an extrasolar world orbiting a star. Hubble scientists announced today that they were able to discover an extrasolar world for the first time by taking an actual image of the newly discovered exoplanet orbiting Fomalhaut — previous discoveries have always been made by detecting changes in the parent star's movement, or by watching the planet momentarily eclipse the star — not by detecting them in images. Hubble's time to shine was overshadowed though by the Keck and Gemini observatories announcing that they had taken pictures of not just one planet, but an entire alien solar system. The images show multiple planets orbiting the star HR 8799 — 3 have been imaged so far."

Chandrayaan-1 Successfully Reaches 100km Lunar Orbit 152

Posted by timothy from the what-hath-man-wrought dept.
Matt_dk writes "Today, Chandrayaan-1 spacecraft has successfully reached its intended operational orbit at a height of about 100 km from the lunar surface. This followed a series of three orbit reduction manoeuvres conducted during the past three days by repeatedly firing the spacecraft's 440 Newton Liquid Engine. The next major event of Chandrayaan-1 mission planned in the coming days is the release of Moon Impact Probe (MIP) from the spacecraft and its eventual hitting of the moon's surface."

The Gene Is Having an Identity Crisis 257

Posted by kdawson from the more-complicated-than-you-thought dept.
gollum123 writes "New large-scale studies of DNA are causing a rethinking of the very nature of genes. A typical gene is no longer conceived of as a single chunk of DNA encoding a single protein. It turns out, for example, that several different proteins may be produced from a single stretch of DNA. Most of the molecules produced from DNA may not even be proteins, but rather RNA. The familiar double helix of DNA no longer has a monopoly on heredity: other molecules clinging to DNA can produce striking differences between two organisms with the same genes — and those molecules can be inherited along with DNA. Scientists have been working on exploring the 98% of the genome not identified as the protein-coding region. One of the biggest of these projects is an effort called the Encyclopedia of DNA Elements, or 'Encode.' And its analysis of only 1% of the genome reveals the genome to be full of genes that are deeply weird, at least by the traditional standard of what a gene is supposed to be and do. The Encode team estimates that the average protein-coding region produces 5.7 different transcripts. Different kinds of cells appear to produce different transcripts from the same gene. And it gets even weirder. Our DNA is studded with millions of proteins and other molecules, which determine which genes can produce transcripts and which cannot. New cells inherit those molecules along with DNA. In other words, heredity can flow through a second channel."

Titan Balloon Mission Being Drafted 82

Posted by timothy from the trial-balloon-for-a-trial-balloon dept.
eldavojohn writes "After Huygens & Cassini corrected our assumptions about Titan (a moon of Saturn), scientists are now debating about their next mission, and one of the choices is the Titan and Saturn System Mission. What makes Titan a good choice? 'Although the atmosphere of Titan is filled with a smoggy orange hydrocarbon haze, it is primarily composed of nitrogen — just like Earth's. In fact, Astrobiologists think Titan's atmosphere may be quite similar to how the Earth's was billions of years ago, before life on our planet generated oxygen.' We also discussed its liquid hydrocarbons earlier this year."

Non-Violent, Cooperative Games? 329

Posted by Soulskill from the play-that-myspace-game-to-befriend-monsters dept.
jandersen writes "While I generally don't play computer games, I do occasionally play games like Crossfire or The Mana World, because they have more of a story line and allow you to go at your own pace. What I don't care much about, though, is that they are still focused on killing monsters and amassing wealth, and it gets very tedious after a while. Are there really no games where the goal isn't so much about increasing your own power and defeating others, but where you instead grow by doing things that benefit others, where enemies shouldn't be killed out of hand, but befriended; where learning, teaching, research and social skills are more important than killing and conquering? Would people be interested in a game of that nature?"

How To Cloak Objects At a Distance 136

Posted by samzenpus from the can-you-see-me-now dept.
KentuckyFC writes "All invisibility cloaks to date work by hiding an object embedded inside them. Now a group of physicists have worked out how to remotely cloak objects that sit outside a cloaking material. The trick is to make the cloaking material with optical properties that are exactly complementary to the space outside them. Complementary means that the material reverses the effect the space has on a plane wave of light passing through it. To an observer this space would appear to vanish. The scientists say that to cloak an object sitting outside the cloaking material, first measure its optical properties and then embed a "complementary image" of the object within the cloak. So a plane wave is first distorted by the object but then restored to a plane by the complementary image of the object within the cloak (abstract). An observer sees nothing. This method has another benefit. Objects hidden in conventional cloaks are blinded because no light enters the cloaked region. But objects that are remotely cloaked like this should still be able to see their surroundings."

Japan To Get 1Gbps Home Fiber Connections 275

Posted by timothy from the yes-but-food-is-cheaper-elsewhere dept.
ashitaka writes "KDDI has announced that they will be launching a 1Gbps Internet service to single-family home and condo users in October. The service is supposedly synchronous, with 1Gbps in both directions, although the article implies that speeds will vary with location. Cost will be 5,985 yen/month (about US$56.50) for the basic Internet and IP phone service. This is intended to compete with NTT, who currently control over 70% of the Japanese FTTH market."

Google Buys a Piece of a Cable To Japan 78

Posted by kdawson from the got-fiber dept.
Googling Yourself writes "Google announced that they will be part of a six-company consortium that will build a high-bandwidth sub-sea fiber optic cable linking the US and Japan. The new cable system, named Unity, is expected initially to increase Trans-Pacific lit cable capacity by about 20 percent, with the potential to add up to 7.68 Terabits per second of bandwidth across the Pacific. The name Unity was chosen to signify a new type of consortium, born out of potentially competing systems, to emerge as a system within a system, offering ownership and management of individual fiber pairs. Rumors that Google would join the consortium had originally surfaced in September last year but the company had declined to confirm or deny the news."
