One Variety of Sea Slugs Cuts Out the Energy Middleman 232
dragonturtle69 writes with this story, short on details but interesting: "These sea slugs, Elysia chlorotica, have evolved the ability to gain energy via photosynthesis. Forget about genetic modifications for sports enhancements. I want to be able to never need to eat again — or do I?"
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."
Mars Images Reveal Evidence of Ancient Lakes 128
Matt_dk writes "Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. Earlier research had suggested that Mars had a warm and wet early history but that between 4 billion and 3.8 billion years ago, before the Hesperian Epoch, the planet lost most of its atmosphere and became cold and dry. In the new study, the researchers analysed detailed images from NASA’s Mars Reconnaissance Orbiter, which is currently circling the red planet, and concluded that there were later episodes where Mars experienced warm and wet periods."
An Open Source Compiler From CUDA To X86-Multicore 71
Gregory Diamos writes "An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."
The Perfect Way To Slice a Pizza 282
iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."
Radar Map of Buried Mars Layers Confirms Climate Cycles 114
Matt_dk writes "A radar instrument on the Mars Reconnaissance Orbiter has essentially looked below the surface of the Red Planet's north-polar ice cap, and found data to confirm theoretical models of Martian climate swings during the past few million years. The new, three-dimensional map using 358 radar observations provides a cross-sectional view of the north-polar layered deposits. 'The radar has been giving us spectacular results,' said Jeffrey Plaut of JPL, a member of the science team for the Shallow Radar instrument. 'We have mapped continuous underground layers in three dimensions across a vast area.'"
AMD Radeon HD 5870 Adds DX11, Multi-Monitor Gaming 195
Vigile writes "Few people will doubt that PC gaming is in need of a significant shot in the arm with the consistent encroachment of consoles and their dominating hold on developers. Today AMD is releasing the Radeon HD 5870 graphics card based on the Evergreen-series of GPUs first demonstrated in June. Besides offering best-in-class performance for a single-GPU graphics board, the new card is easily the most power efficient in terms of idle power consumption and performance per watt. Not only that, but AMD has introduced new features that could help keep PC gaming in the spotlight, including the first DirectX 11 implementation and a very impressive multi-monitor gaming technology, Eyefinity, which we discussed earlier this month. The review at PC Perspective includes the full gamut of gaming benchmarks in both single- and dual-GPU configurations as well as videos of Eyefinity running on three 30" displays."
