Aral Sea May Recover; Dead Sea Needs a Lifeline 131

An anonymous reader writes "It's a tale of two seas. The drying up of the Aral Sea is considered one of the greatest environmental catastrophes in history, but the northern sector of the sea, at least, is showing signs of life. A dam completed in 2005 has increased the North Aral's span by 20 percent, and birds, fish, and people are all returning to the area. Meanwhile, the Dead Sea is still in the midst of precipitous decline, since too much water is being drawn out of the Jordan River for thirsty populations and crops. To keep the sea from shrinking more, scientists are pushing an ambitious scheme called the 'Red-Dead conduit,' which would channel huge amounts of water from the Red Sea to the Dead Sea. However, the environmental consequences of such a project may be troubling."

Planned Nuclear Reactors Will Destroy Atomic Waste 344

separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

Lag Analysis For the PlayStation Move 71

The $64,000 question about Sony's upcoming motion control system, the PlayStation Move, is how responsive it will be compared to traditional console controllers and its counterparts from Nintendo and Microsoft. Eurogamer slowed down videos of Sony's tech demo software to establish a rough baseline latency that developers will have to work with. Quoting: "While exact latency measurements aren't possible in these conditions, a ballpark idea of the level of response isn't a problem at all. The methodology is remarkably straightforward. Keep your hand as steady as possible, then make fast motions with the controller. Count the frames between your hand moving, and the motion being carried out on-screen. Equally illuminating is to stop your movement suddenly, then count the frames necessary for your on-screen counterpart to catch up. While not 100 per cent accurate, repeat the process enough times and the frame difference becomes fairly evident. Bearing all of that in mind, and recognizing that we don't know how much latency the display itself is adding, I'd say that a ballpark figure of around 133ms of controller lag (give or take a frame) seems reasonable, certainly not the ultra-fast crispness of response we see from games like Burnout Paradise or Modern Warfare, but fine for most of the applications you would want from such a controller."

15-Year-Old Student Discovers New Pulsar 103

For the second time in as many years, a student has made a discovery while participating in the Pulsar Search Collaboratory (PSC), a joint program between the National Radio Astronomy Observatory and West Virginia University designed to get students and teachers involved in analyzing data from the Robert C. Byrd Green Bank Telescope (GBT). This time it was high school sophomore Shay Bloxton, who discovered a brand new pulsar. "For Bloxton, the pulsar discovery may be only her first in a scientific career. 'Participating in the PSC has definitely encouraged me to pursue my dream of being an astrophysicist,' she said, adding that she hopes to attend West Virginia University to study astrophysics. Late last year, another West Virginia student, from South Harrison High School, Lucas Bolyard, discovered a pulsar-like object called a rotating radio transient. His discovery also came through participation in the PSC."

Researchers Pooh-Pooh Algae-Based Biofuel 238

Julie188 writes "Researchers from the University of Virginia have found that current algae biofuel production methods consume more energy, have higher greenhouse gas emissions and use more water than other biofuel sources, such as switchgrass, canola and corn. The researchers suggest these problems can be overcome by situating algae production ponds behind wastewater treatment facilities to capture phosphorous and nitrogen — essential algae nutrients that otherwise need to come from petroleum."

Mozilla Firefox 3.6 Released 284

Shining Celebi writes "Mozilla has released Firefox 3.6 today, which adds support for Personas, lightweight themes that can be installed without restarting the browser, and adds further performance improvements to the new Tracemonkey Javascript engine. One of the major goals of the release was to improve startup time and general UI responsiveness, especially the Awesomebar. You can read the full set of release notes here."

European Commission Approves Oracle-Sun Merger 144

rubycodez writes "The anti-trust body of the EU, the European Commission, has approved Oracle's acquisition of Sun Microsystems, believing competition would be preserved. It saw PostgreSQL as a viable independent alternative to MySQL and that market access to Java would not be restricted. Uncertainty about Sun's future has cost over a billion dollars in lost sales in the past year."

Mozilla Rolls Out Firefox 3.6 RC, Nears Final 145

CWmike writes "Mozilla has shipped a release candidate build of Firefox 3.6 that, barring problems, will become the final, finished version of the upgrade. Firefox 3.6 RC1, which followed a run of betas that started in early November, features nearly 100 bug fixes from the fifth beta that Mozilla issued Dec. 17. The fixes resolved numerous crash bugs, including one that brought down the browser when it was steered to Yahoo's front page. Another fix removed a small amount of code owned by Microsoft from Firefox. The code was pointed out by a Mozilla contributor, and after digging, another developer found the original Microsoft license agreement. 'Amusingly enough, it's actually really permissive. Really the only part that's problematic is the agreement to "include the copyright notice ... on your product label and as a part of the sign-on message for your software product,"' wrote Kyle Huey on Mozilla's Bugzilla. Even so, others working on the bug said the code needed to be replaced with Mozilla's own."

Placebo Effect Caught In the Act In Spinal Nerves 167

SerpensV passes along the news that German scientists have found direct evidence that the spinal cord is involved in the placebo effect (whose diminishing over time we discussed a bit earlier). "The researchers who made the discovery scanned the spinal cords of volunteers while applying painful heat to one arm. Then they rubbed a cream onto the arm and told the volunteers that it contained a painkiller, but in fact it had no active ingredient. Even so, the cream made spinal-cord neural activity linked to pain vanish. 'This type of mechanism has been envisioned for over 40 years for placebo analgesia,' says Donald Price, a neuroscientist at the University of Florida in Gainesville, who was not involved in the new study. 'This study provides the most direct test of this mechanism to date.'"

Possible Dark Matter Signs At the Core 234

Scientific American has a piece on speculation that dark matter may be behind diffuse radiation in the galactic center. Beginning in 2003, researchers led by Douglas Finkbeiner noticed a curious excess of microwave radiation in the WMAP data, after all known sources of such radiation were accounted for. Data from NASA's Fermi Gamma-Ray Space Telescope resulted in a similar anomaly in gamma rays. "A paper posted to the physics preprint Web site arXiv.org on October 26 and submitted to the Astrophysical Journal points to a possible signature of dark matter in the Milky Way, although the study's authors are careful to keep their observations empirical and table such speculation... In the new paper [the researchers] describe the Fermi gamma-ray haze and make the claim that it confirms the synchrotron origin of the WMAP microwave haze. And as with the microwave haze, the authors argue that the electrons responsible for the gamma-ray haze appear to originate from an unknown astrophysical process. ... 'We are absolutely in the process of exploring the Fermi haze in the context of dark matter physics,' [one of them] says."

PLplot Notes Its 10,000th Commit 66

iliketrash writes "From the PLplot development team is the announcement of their 10,000th commit: 'PLplot is a cross-platform software package for creating scientific plots that has been in continuous development since its inception 17 years ago. On May 23, 2009 the PLplot developers quietly celebrated our ten thousandth commit since our initial software repository was populated back in May 1992. This longevity puts PLplot in some select company amongst open-source software projects. We may even be unique within this group because all PLplot development has been done by volunteers in their spare time. The enthusiasm for PLplot development continues; we have averaged more than 100 commits per month over the last year which is double our 17-year average, and we are looking forward to the celebration of our next ten thousand commits!'"

Comment SP2=Blue Screen of Death (Score 1) 334

I installed this on my wife computer no problem Vista Home. When I tried installing it on my Vista Ultimate machine Toshiba U205 I received the Blue Screen of Death during the reboot. I came up in safe mode, rolled back the change. Then started up in safe mode, shutdown unnecessary services, then installed SP2 and it installed fine.
