Hubble To Use the Moon To View Transit of Venus 37

Posted by Soulskill from the oh-yeah-it-was-easy-i-just-used-the-moon dept.
astroengine writes "As we recently discussed, on June 5 or 6 this year — the exact time and date depends on where you are in the world — Venus will be visible as a small black circle crossing the disk of the sun. Usually, the Hubble Space Telescope would have no business observing this event — the sun is too close for its optics. But plans are afoot for Hubble to observe the reflected sunlight bouncing off the lunar surface during the transit. As the sunlight will pass through the Venusian atmosphere, the transit will provide invaluable spectroscopic data about Venus' atmospheric composition. This, in turn, will help astronomers in characterizing the atmospheres of planets orbiting other stars."

DHS Asked Gas Pipeline Firms To Let Attackers Lurk Inside Networks 114

Posted by Soulskill from the what-could-possibly-go-wrong dept.
wiredmikey writes "According to reports, which were confirmed Friday by ICS-CERT (PDF), there has been an active cyber attack campaign targeting the natural gas industry. However, it's the advice from the DHS that should raise some red flags. 'There are several intriguing and unusual aspects of the attacks and the U.S. response to them not described in Friday's public notice,' Mark Clayton wrote. 'One is the greater level of detail in these alerts than in past alerts. Another is the unusual if not unprecedented request to leave the cyber spies alone for a little while.' According to the source, the companies were 'specifically requested in a March 29 alert not to take action to remove the cyber spies if discovered on their networks, but to instead allow them to persist as long as company operations did not appear to be endangered.' While the main motive behind the request is likely to gain information on the attackers, letting them stay close to critical systems is dangerous. The problem lies in the complexities of our critical infrastructures and the many highly specialized embedded systems that comprise them."

Philips Releases 100W-Equivalent LED Bulb, Runs On Just 23 Watts 529

Posted by Soulskill from the it's-not-easy-being-green dept.
MrSeb writes "The Light Fair convention kicks off in Las Vegas this week, so there will be any number of related announcements coming soon. Lighting giant Philips is starting things off early with the announcement of their 100W-equivalent LED bulb, the AmbientLED 23W. The model produces 1700 lumens, putting it at a very respectable 73.9 lm/W. The unveiling comes shortly after Philips' L Prize bulb was made available to consumers. That bulb currently sells for about $60 and is a more efficient light source, capable of 94 lm/W. The two use similar designs; for example, both take advantage of remote phosphor, but the AmbientLED 23W (it will be called the EnduraLED in non-consumer applications) is brighter and lacking in some of the performance characteristics of the L Prize winner, including luminous efficiency and color accuracy. Philips' 100W-equivalent bulb will be available some time in the fourth quarter. Pricing has yet to be announced, but it will likely be well over $30."

eldavojohn writes "Details are thin, but the long-covered Oracle v. Google trial has at least partially been decided in favor of Oracle. The jury says Google violated copyrights with Android when it used Java APIs to design the system. Google moved for a mistrial after hearing the incomplete decision. The patent infringement accusations have yet to be ruled upon."

Ask Slashdot: What's a Good Tool To Detect Corrupted Files? 247

Posted by Soulskill from the easy,-just-d%wn!o@%-Km3#-r*(;. dept.
Volanin writes "Currently I use a triple boot system on my Macbook, including MacOS Lion, Windows 7, and Ubuntu Precise (on which I spend the great majority of my time). To share files between these systems, I have created a huge HFS+ home partition (the MacOS native format, which can also be read in Linux, and in Windows with Paragon HFS). But last week, while working on Ubuntu, my battery ran out and the computer suddenly powered off. When I powered it on again, the filesystem integrity was OK (after a scandisk by MacOS), but a lot of my files' contents were silently corrupted (and my last backup was from August...). Mostly, these files are JPGs, MP3s, and MPG/MOV videos, with a few PDFs scattered around. I want to get rid of the corrupted files, since they waste space uselessly, but the only way I have to check for corruption is opening them up one by one. Is there a good set of tools to verify the integrity by filetype, so I can detect (and delete) my bad files?"

Astronomers Find Most Distant Protocluster of Galaxies 129

Posted by Soulskill from the since-before-your-sun-burned-hot-in-space dept.
The Bad Astronomer writes "Using the monster 8.2-meter Subaru telescope, astronomers have identified the most distant cluster of galaxies ever found: a collection of galaxies at a staggering distance of 12.7 billion light years. This is the most distant cluster ever seen that has been confirmed spectroscopically (PDF). Technically, it's a protocluster, since it's so young — seen only a billion years after the Big Bang itself — the cluster must still be in the process of formation."

U.S. In Danger of Losing Earth-Observing Satellite Capability 258

Posted by Soulskill from the well-that's-embarrassing dept.
New submitter crazyjj writes "As reported in Wired, a recent National Research Council report indicates a growing concern for NASA, the NOAA, and USGS. While there are currently 22 Earth-observing satellites in orbit, this number is expected to drop to as low as six by the year 2020. The U.S. relies on this network of satellites for weather forecasting, climate change data, and important geologic and oceanographic information. As with most things space and NASA these days, the root cause is funding cuts. The program to maintain this network was funded at $2 billion as recently as 2002, but has since been scaled back to a current funding level of $1.3 billion, with only two replacement satellites having definite launch dates."

Scientists 'Switch Off' Brain Cell Death In Mice 78

Posted by Soulskill from the are-you-pondering-what-i'm-pondering dept.
fishmike sends this excerpt from a Reuters report: "Scientists have figured out how to stop brain cell death in mice with brain disease and say their discovery deepens understanding of the mechanisms of human neurodegenerative diseases such as Alzheimer's and Parkinson's. British researchers writing in the journal Nature (abstract) said they had found a major pathway leading to brain cell death in mice with prion disease, the mouse equivalent of Creutzfeld-Jacob Disease (CJD). ... Mallucci's team found that the buildup of mis-folded proteins in the brains of mice with prion disease activated a natural defense mechanism in cells, which switches off the production of new proteins. This would normally switch back on again, the researchers explained, but in these ill mice the continued build-up of misshapen proteins keeps the switch turned off. This is the trigger point leading to brain cell death, because key proteins essential for cell survival are not made. By injecting a protein that blocks the "off" switch, the scientists were able to restore the production of the survival proteins and halt the neurodegeneration."

Methane Producing Dinosaurs May Have Changed Climate 264

Posted by samzenpus from the it's-getting-hot-in-here dept.
Hugh Pickens writes "The Telegraph reports that huge plant-eating dinosaurs called sauropods may have produced enough greenhouse gas by breaking wind to alter the Earth's climate. Scientists believe that, just as in cows, methane-producing bacteria aided the digestion of sauropods by fermenting their plant food. 'A simple mathematical model suggests that the microbes living in sauropod dinosaurs may have produced enough methane to have an important effect on the Mesozoic climate,' says study leader Dr Dave Wilkinson. 'Indeed, our calculations suggest that these dinosaurs could have produced more methane than all modern sources — both natural and man-made — put together.' The key factor is the total mass of the animals which included some of the largest animals to walk the Earth, such as Diplodocus, which measured 150 feet and weighed up to 45 tons. Medium-sized sauropods weighed about 20 tons and lived in herds of up to a few tens of individuals per square kilometer so global methane emissions from the animals would have amounted to around 472 million tons per year, the scientists calculated. Sauropods alone may have been responsible for an atmospheric methane concentration of one to two parts per million (ppm), say the scientists and studies have suggested that the Earth was up to 10C (18F) warmer in the Mesozoic Era. ''The Mesozoic trend to sauropod gigantism led to the evolution of immense microbial vats unequaled in modern land animals. Methane was probably important in Mesozoic greenhouse warming. Our simple proof-of-concept model suggests greenhouse warming by sauropod megaherbivores could have been significant in sustaining warm climates.'"

Verizon To Begin Offering "Text To 911" Service 194

Posted by samzenpus from the alert-the-authorities dept.
An anonymous reader writes "In a move that will likely elicit a 'why didn't they implement that sooner?' response, Verizon in the next 12 months will begin implementing a 'text to 911' feature that, as the name implies, will enable users contact 911 operators via text message to report an emergency. The feature will be particularly helpful for the hearing and/or speech impaired, and for folks who find themselves in dangerous situations where making a voice 911 call isn't advisable. Beginning in early 2013, Verizon will start rolling out the feature in various metropolitan areas before progressing to a nationwide rollout soon thereafter. In many respects, this move has been a long time coming, and something the FCC has been championing for a few years."

Microsoft Creates Kinect-Like System Using Laptop Speaker & Microphone 169

Posted by samzenpus from the echo-of-the-future dept.
MrSeb writes "Microsoft Research, working with the University of Washington, has developed a Kinect-like system that uses your computer's built-in microphone and speakers to provide object detection and gesture recognition, much in the same way that a submarine uses sonar. Called SoundWave, the new technology uses the Doppler effect to detect any movements and gestures in the proximity of a computer. In the case of SoundWave, your computer's built-in speaker is used to emit ultrasonic (18-22KHz) sound waves, which change frequency depending on where your hand (or body) is in relation to the computer. This change in frequency is measured by your computer's built-in microphone, and then some fairly complex software works out your motion/gesture. The obvious advantage of SoundWave over a product like Kinect is that it uses existing, commodity hardware; it could effectively equip every modern laptop with a gesture-sensing interface. The Microsoft Research team is reporting a 90-100% accuracy rate for SoundWave, even in noisy environments."

How the Syrian Games Industry Crumbled Under Sanctions and Violence 141

Posted by samzenpus from the no-games-no-peace dept.
Fluffeh writes "Syria's games industry now looks like just another collateral casualty of dictator Bashar Al-Assad's struggle to hold power. 'Life for Syrian game developers has never been better,' joked Falafel Games founder Radwan Kasmiya, 'You can test the action on the streets and get back to your desktop to script it on your keyboard.' Any momentum Syria may have been building as a regional game development hub slowed considerably in 2004, when then-US President George W. Bush levied economic sanctions against the country. Under the sanctions, Syria's game developers found themselves cut off from investment money they needed to grow, as well as from other relationships that were just as important as cash. 'Any [closure of opportunity] is devastating to a budding games company as global partnerships are completely hindered,' said Rawan Sha'ban of the Jordanian game development company Quirkat. 'Even at the simplest infrastructure level, game development engines [from the US] cannot be purchased in a sanctioned country.'"

Aussie Politician Threatens To Contact Employers of Satirical Article "Likers" 195

Posted by samzenpus from the what-not-to-do dept.
Chuq writes "Tasmanian Liberal candidate for Bass, Andrew Nikolic, was the subject of a satirical article by NewExaminer on Facebook. Nikolic didn't like it, which is understandable. However he then went to considerable lengths to identify the people who liked the article, find out their employers (via their Facebook profiles) and 'name and shame' them on a follow-up post on his own page. Andrew Nikolic has a history of poorly handling conflicting views on his Facebook page, resulting in creation of another page, 'Andrew Nikolic blocked me.'"

South Korea Plans Hashtag-Inspired Skyscraper 117

Posted by samzenpus from the ampersand-estates dept.
cylonlover writes "The hashtag or "#" symbol has taken on a lot more use in recent years, especially with the rise of social media tools like Twitter, where it's used to highlight popular topics. So in a way, it's a fitting model for an apartment building designed to act as a self-contained neighborhood, which is exactly the idea behind the Cross # Towers planned for South Korea. Dutch architectural firm, Bjarke Ingels Group (BIG), is modeling the look of the proposed building after the familiar symbol, by placing two interlocking bridges between two skyscrapers, which will also support outdoor park areas to mimic the sort of spaces you'd normally find on the ground."
