An anonymous reader writes with this quote from a story at El Reg about an early look at the Silverlight 4 beta: "There are ... major changes to Silverlight's out-of-browser functionality, a loose equivalent to Adobe Systems' AIR runtime for Flash. Even when fully sandboxed, which means having the same permissions that would apply to a browser-hosted Silverlight applet, out-of-browser applications get an HTML control, custom window settings, and the ability to fire pop-up notifications. ... Unfortunately, some of these features are not what they first appear. The HTML control in Silverlight 4 is not a new embedded browser from Microsoft, but uses components from Internet Explorer on Windows, or Safari on the Mac, which means that the same content might render differently. The HTML control only works out-of-browser, and simply displays a blank space if browser-hosted. Clipboard support is text-only in the Silverlight 4 beta, though this could change for the full release. More seriously, COM automation is a Windows-only feature, introducing differentiation between the Mac and Windows implementations."

eldavojohn writes "Both the EU and US are using a strategy to merge what used to be two separate searches: the search for exoplanets that may harbor life and the search for dark energy. In an effort to develop 'robust, low-risk missions that maximize the scientific return,' the article analyzes how, without any changes, a space-based dark energy telescope could also check for microlensing events indicating an exoplanet."

Hugh Pickens writes "The Telegraph reports that 4,000 microscopic worms were onboard Space Shuttle Atlantis when it launched today. Their mission: to help experts in human physiology understand more about what triggers the body to build and lose muscle. The worms are bound for the Japanese Experiment Module 'Kibo' on the International Space Station, where they will experience the same weightless conditions which can cause dramatic muscle loss, one of the major health concerns for astronauts. 'If we can identify what causes the body to react in certain ways in space we establish new pathways for research back on earth,' says Dr. Nathaniel Szewczyk."

dag writes "Drupal 6 Social Networking is an interesting book about how to build social networks and why Drupal is a good choice as a platform for building communities. Even if you don't have any Drupal experience yet, this book explains what is needed when you start from scratch and looks at the different facets of a social network." Keep reading for the rest of Dag's review.

eldavojohn writes "2009 has been an interesting year for NASA — from a new strategy to even closer ties with an old enemy. So it's perhaps no surprise that NASA has publicly stated that they are ready to team up with China. NASA Chief Charles Bolden said, 'I am perfectly willing, if that's the direction that comes to me, to engage the Chinese in trying to make them a partner in any space endeavor. I think they're a very capable nation. They have demonstrated their capability to do something that only two other nations that have done — that is, to put humans in space. And I think that is an achievement you cannot ignore. They are a nation that is trying to really lead. If we could cooperate we would probably be better off than if we would not.' While the budget of the China National Space Administration is a fraction of NASA's, partnering with them has been considered since 2008. In possibly related news, rumors are circulating of the Obama administration cutting NASA's budget by ten percent for fiscal year 2011 despite the success of Monday's Atlantis launch. Considering the Augustine panel's recommendations, such a cut could halt US human space flight for a decade."

coondoggie writes "A Tang soufflé perhaps? Yum. A new book out this week will tell you everything you wanted to know about cooking and eating in space. The Astronaut's Cookbook: Tales, Recipes, and More — penned by NASA veterans Charles Bourland and Gregory Vogt — offers up a number of recipes as well a history of space feasting just in time for Thanksgiving, if you are so inclined. The book includes a number of interesting space food facts: Soviet cosmonaut Gherman Titov was the first human to consume food in space."

RobGoldsmith sends in a Space Fellowship piece (which seems to be a press release) about New Zealand's entry into the space age. "Private New Zealand aerospace company Rocket Lab completed its final ground-based test today and is now ready to launch New Zealand into the space race with its Atea-1 launch vehicle. The first high-altitude launch of Atea-1 is scheduled for the end of November this year. Once Atea-1 has successfully concluded the development phase it will be the first privately built rocket launched from the Southern Hemisphere to enter space. The article features a new CGI movie on the launch."

GringoChapin writes in with coverage from Space.com on the Leonid meteor shower, adding "Folks from the United States will want to start watching at 0100 Pacific, 0400 Eastern, and those in Europe from 0100 local time until dawn." "One of the best annual meteor showers will peak in the pre-dawn hours Tuesday, and for some skywatchers the show could be quite impressive. The best seats are in Asia, but North American observers should be treated to an above average performance of the Leonid meteor shower, weather permitting." Sky and Telescope's coverage is excellent as usual, and they also have tips for beginning and advanced meteor observers.

CWmike writes "As amazing as today's supercomputing systems are, they remain primitive and current designs soak up too much power, space and money. And as big as they are today, supercomputers aren't big enough — a key topic for some of the estimated 11,000 people now gathering in Portland, Ore. for the 22nd annual supercomputing conference, SC09, will be the next performance goal: an exascale system. Today, supercomputers are well short of an exascale. The world's fastest system at Oak Ridge National Laboratory, according to the just released Top500 list, is a Cray XT5 system, which has 224,256 processing cores from six-core Opteron chips made by Advanced Micro Devices Inc. (AMD). The Jaguar is capable of a peak performance of 2.3 petaflops. But Jaguar's record is just a blip, a fleeting benchmark. The US Department of Energy has already begun holding workshops on building a system that's 1,000 times more powerful — an exascale system, said Buddy Bland, project director at the Oak Ridge Leadership Computing Facility that includes Jaguar. The exascale systems will be needed for high-resolution climate models, bio energy products and smart grid development as well as fusion energy design. The latter project is now under way in France: the International Thermonuclear Experimental Reactor, which the US is co-developing. They're expected to arrive in 2018 — in line with Moore's Law — which helps to explain the roughly 10-year development period. But the problems involved in reaching exaflop scale go well beyond Moore's Law."

oliderid sends along a BBC report on progress toward Europe's home-grown GPS system. The Galileo concept will get an initial test via four "pathfinder" satellites that will be the first in the Galileo constellation. Galileo is intended to be complementary with the US GPS system — when all 30 Galileo birds are flying, a receiver with both GS and Galileo capability should enjoy 1-meter positional accuracy, vs. the several meters available through GPS alone, according to the article. There's a video tour of the facility where the pathfinders are being built. "After all the wrangling, the delays, and the furor over cost, Europe's version of GPS is finally starting to take shape. Due for launch in pairs in late 2010 and early 2011, the 'pathfinders' will form a mini-constellation in the sky. They will transmit the navigation signals that demonstrate the European system can become a reality."

An anonymous reader writes "Robert X. Cringely once again educates and amuses with his take on how we could clean up the garbage that's in orbit around Earth. I cannot vouch for his math, but it makes sense to me. Quoting: 'We’d start in a high orbit, above the space junk, because we could trade that altitude for speed as needed, simply by flying lower, trading potential energy for kinetic. Dragging the net behind a little unmanned spacecraft, my idea would be to go past each piece of junk in such a way that it not only lodges permanently in the net, but that doing so adds kinetic energy (hitting at shallow angles to essentially tack like a sailboat off the debris). But wait, there’s more! You not only have to try to get energy from each encounter, it helps if — like in a game of billiards or pool — each encounter results in an effective ricochet sending the net in the proper trajectory for its next encounter. Rinse and repeat 18,000 times.'"

tugfoigel writes "Astrophysicists at the University of Warwick and Kiel University have discovered two bodies the size of earth with oxygen-rich atmospheres — however, there is a disappointing snag for anyone looking for a potential home for alien life, or even a future home for ourselves. These are not planets, but are actually two unusual white dwarf stars." The objects, 220 and 400 light-years distant, are believed to be remnants of stars between 7 and 10 solar masses. Such stars, the largest that evolve to white dwarves, have been sought for years. If the stars were a little more massive they would collapse to neutron stars, or so the theory goes. Here is the paper on the arXiv.

Pickens writes "The Telegraph reports that the Vatican's Pontifical Academy of Sciences is holding its first ever conference on alien life, the discovery of which would have profound implications for the Catholic Church. For centuries, theologians have argued over what the existence of life elsewhere in the universe would mean for the Church. Among other things, extremely alien-looking aliens would be hard to fit with the idea that God 'made man in his own image' and Jesus Christ's role as savior would be confused; would other worlds have their own Christ-figures, or would Earth's Christ be universal? Just as the Church eventually made accommodations after Copernicus and Galileo showed that the Earth was not the center of the universe, and when it belatedly accepted the truth of Darwin's theory of evolution, Catholic leaders say that alien life can be aligned with the Bible's teachings. 'Just as a multiplicity of creatures exists on Earth, so there could be other beings, also intelligent, created by God,' says Father Jose Funes, a Jesuit astronomer at the Vatican Observatory and one of the organizers of the conference. Others do not agree. 'If you look back at the history of Christian debate on this, it divides into two camps. There are those that believe that it is human destiny to bring salvation to the aliens, and those who believe in multiple incarnations,' says Paul Davies, a theoretical physicist. 'The multiple incarnations is a heresy in Catholicism.'"

coondoggie writes "NASA's long-running Mars rover Spirit is stuck in a sand trap — a situation the space agency would like to fix. Yesterday NASA said it will begin what it called the long process of extricating Spirit by sending commands that could free the rover. Spirit has been stuck in a place NASA calls 'Troy' since April 23, when the rover's wheels broke through a crust on the surface that was covering bright-toned, slippery sand underneath. After a few drive attempts to get Spirit out in the subsequent days, it began sinking deeper in the sand trap. Driving was suspended to allow time for tests and reviews of possible escape strategies, NASA stated."

DynaSoar writes "On Friday November 13th, ESA'a Rosetta probe will get its third and final gravity assist slingshot from Earth on its way to its primary targets, the asteroid Lutetia and Comet 67P/Churyumov-Gerasimenko. But the slingshot itself will allow ESA scientists to examine the trajectory for unusual changes seen in several other probes' velocities. An unaccountable variation was first noticed as excess speed in Pioneers 11 and 12, and has since been called the Pioneer Anomaly. More troubling than mere speed increase is the inconsistency of the effect. While Galileo and NEAR had appreciable speed increases, Cassini and Messenger did not. Rosetta itself gained more speed than expected from its 2005 fly-by, but only the expected amount from its 2007 fly-by. Several theories have been advanced, from mundane atmospheric drag to exotic variations on special relativity, but none are so far adequate to explain both the unexpected velocity increases and the lack of them in different instances. Armed with tracking hardware and software capable of measuring Rosetta's velocity within a few millimeters per second while it flies past at 45,000 km/hr, ESA will be gathering data which it hopes will help unravel the mystery."

astroengine writes "Physicists are getting excited about the possibility of micro-black holes (MBH) being produced by the LHC and an international group of researchers have done the math to see what kind of impact they could have on the Earth. Unfortunately, if you're a megalomaniac looking for your next globe-eating weapon, you can scrub MBHs off your WMD list. If a speedy MBH is produced, flying through our planet, it will only have a few seconds to accrete the mass of a few atoms. It would then be lost to space where it will evaporate. If a slow MBH is produced, dropping into the Earth where it sits for a few billion years, the results are even more boring."

turtleshadow writes "Brian Krebs of the Security Fix Blog analyzes the McColo Spamming one year later and asks an interesting question: 'How does one renovate and recoup the lost trust to the slums of the Internet and reclaim back all the domains and IPs that have been blacklisted?' Indeed, the economic benefits abound when a huge swath of illegal and annoying activity ceases — but given the basic design of the Internet, what happens over the long run to IP space and DNS when hosting companies come and go and vary in their trustworthiness? So too, now Geocities is dead [as a business], but does that still live in your filter list? It still appears in OpenDNS under several policy categories. How, in a few years, will I tell if some Hosting/Colo sold me Whitechapel Road/Ventura Avenue for Mayfair/Boardwalk prices, and no one is going to accept my mail from a former slum? When do you, if ever, roll back the blacklists and filters for 'dead' threats and spammers?"

coondoggie writes "NASA and the European Space Agency (ESA) are aiming to cooperate on all manner of robotic orbiters, landers and exploration devices for a future trip to Mars. Specifically, NASA and ESA recently agreed to consider the establishment of a new joint initiative to define and implement their scientific, programmatic, and technological goals for the exploration of Mars. The program would focus on several launch opportunities with landers and orbiters conducting astrobiological, geological, geophysical, climatological, and other high-priority investigations and aiming at returning samples from Mars in the mid-2020s."

PBH submitted a link to a really amazing composite image of the Milky Way released by NASA. They combined infrared, visible, and x-ray images taken by Spitzer, Hubble, and Chandra to create one beautiful image to commemorate the 400 years since 1609, when Galileo looked up.

DangerFace writes "Scientists are set to unveil a lightweight system they say makes an operating system significantly more resistant to rootkits without degrading its performance. The hypervisor-based system is dubbed HookSafe, and it works by relocating kernel hooks in a guest OS to a dedicated page-aligned memory space that's tightly locked down. The team installed HookSafe on a machine running Ubuntu 8.04, and found the system successfully prevented nine real-world rootkits targeting that platform from installing or hiding themselves. The program was able to achieve that protection with only a 6 percent reduction in performance benchmarks."
