doperative writes "Much conventional wisdom about programs written by volunteers is wrong. The authors took money for research from Microsoft, long the archenemy of the open-source movement — although they assure readers that the funds came with no strings attached. Free programs are not always cheaper. To be sure, the upfront cost of proprietary software is higher (although open-source programs are not always free). But companies that use such programs spend more on such things as learning to use them and making them work with other software"

Phoghat writes "A new batch of images has been released by the HiRISE camera on the Mars Reconnaissaince Orbiter and as usual they are stunning. In the first image, there is a lot going on! Numerous dust devil tracks have left criss cross marks. The second is an image of what could have been a once habitable lake. There are more, including a possible future landing site."

An anonymous reader writes "It's been known that ZFS is coming to Linux in the form of a native kernel module done by the Lawrence Livermore National Laboratory and KQ Infotech. The ZFS module is still in closed testing on KQ infotech's side (but LLNL's ZFS code is publicly available), and now Phoronix has tried out the ZFS file-system on Linux and carried out some tests. ZFS on Linux via this native module is much faster than using ZFS-FUSE, but the Solaris file-system in most areas is not nearly as fast as EXT4, Btrfs, or XFS."

An anonymous reader writes "For the first time, there is no need to chemically fix, stain or cut cells in order to study them. Instead, whole living cells are fast-frozen and studied in their natural environment. The new method delivers an immediate 3-D image, thereby closing a gap between conventional microscopic techniques. The new microscope delivers a high-resolution 3-D image of the entire cell in one step. This is an advantage over electron microscopy, in which a 3-D image is assembled out of many thin sections. This can take up to weeks for just one cell. Also, the cell need not be labeled with dyes, unlike in fluorescence microscopy, where only the labeled structures become visible. The new X-ray microscope instead exploits the natural contrast between organic material and water to form an image of all cell structures. Dr. Gerd Schneider and his microscopy team at the Institute for Soft Matter and Functional Materials have published their development in Nature Methods (abstract)."

hasanabbas1987 writes "Touchscreens have been with us for quite some time now and we have seen all kinds of them: resistive touch, capacitive, multi-touch, etc. However, Nokia's research lab in Tampere, Finland has developed a rather unique kind of touchscreen: a touchscreen made of ice. Well, to be honest, it's not really a touchscreen for everyday use, nor is it very portable, as the rig includes a projector and some infrared cameras (PDF) which are connected to a computer, but after all it's a touchscreen made out of ice and that is quite remarkable. Nokia says this 'playful experiment' reveals that interactive touch displays can be built anywhere, and we are very sure that Mr. Freeze from Batman will be highly interested in the project."

vbraga writes "With the release of Mathematica 8, it now allows input through free-form English instead of the Mathematica syntax, just like the Wolfram|Alpha engine. The results are impressive. From the blog post: 'I routinely found myself using free-form linguistics as an integral part of longer computations — randomly interspersing Mathematica syntax and free-form linguistics on different lines in a Mathematica session, and just using whichever was most convenient for a particular input. And here's an exciting part: in Mathematica 8 the free-form linguistics doesn't just operate line-by-line. It knows the context in which it's used in a notebook, so you can use it to build things up.'"

broknstrngz tips news of an announcement today from NASA about the discovery of a black hole in the M100 galaxy, roughly 50 million light-years from Earth. The discovery is notable because, if confirmed, it's now the youngest known black hole, born from the remains of a supernova we observed in 1979. Bad Astronomer Phil Plait explains why scientists think it collapsed to a black hole, rather than a neutron star: "The way a neutron star emits X-rays is different than that of a black hole. As a neutron star cools, the X-ray emission will fade. However, a black hole blasts out X-rays as material falls in; that stuff forms a flat disk, called an accretion disk, around the black hole. As this matter falls onto the newly created black hole, it gets heated to unimaginable temperatures — millions of degrees — and blasts out X-rays. In that case, the X-rays emitted would be steady over time. What astronomers have found is that the X-rays from SN1979c have been steady in brightness over observations from 1995 – 2007. This is very strong evidence that the star’s core did indeed collapse into a black hole." He also warns that we're not certain quite yet, and we'll have to keep our eye on it to make sure it's not a pulsar.

CWmike writes "Columbia law professor Tim Wu, who coined the term 'net neutrality,' now says that Apple is the company that most endangers the freedom of the Internet. Wu recently published the book The Master Switch: The Rise and Fall of Information Empires, in which he details what he calls 'information empires' such as AT&T, NBC, Facebook, and Google. He told The New York Times, 'It's largely a story of the American affection for information monopolists and the consequences of that fondness.' When asked whether the Internet could similarly be controlled by large companies, he told the Times: 'I know the Internet was designed to resist integration, designed to resist centralized control, and that design defeated firms like AOL and Time Warner. But firms today, like Apple, make it unclear if the Internet is something lasting or just another cycle.' Asked which companies he feared most, Wu replied: 'Right now, I'd have to say Apple.'" Wu has been in the news a bit lately.

Twice a year, Top500.org publishes a list of supercomputing benchmarks from sites around the world; the new results are in. Reader jbrodkin writes "Microsoft says a Windows-based supercomputer has broken the petaflop speed barrier, but the achievement is not being recognized by the group that tracks the world's fastest supercomputers, because the same machine was able to achieve higher speeds using Linux. The Tokyo-based Tsubame 2.0 computer, which uses both Windows and Linux, was ranked fourth in the world in the latest Top 500 supercomputers list. While the computer broke a petaflop with both operating systems, it achieved a faster score with Linux, denying Microsoft its first official petaflop ranking." Also in Top-500 news, reader symbolset writes with word that "the Chinese Tianhe-1A system at the National Supercomputer Center in Tianjin takes the top spot with 2.57 petaflops. Although the US has long held a dominant position in the list things now seem to be shifting, with two of the top spots held by China, one by Japan, and one by the US. In the Operating System Family category Linux continues to consolidate its supercomputing near-monopoly with 91.8% of the systems — up from 91%. High Performance Computing has come a long way quickly. When the list started as a top-10 list in June of 1993 the least powerful system on the list was a Cray Y-MP C916/16526 with 16 cores driving 13.7 RMAX GFLOP/s. This is roughly the performance of a single midrange laptop today."

explosivejared writes "The Economist has a story on the increasing scientific productivity of countries like China, India, and Brazil relative to the field's old guards in America, Europe, and Japan. Scientific productivity in this sense includes percent of GDP spent on R&D and the overall numbers of researchers, scholarly articles, and patents that a country produces. The article notes increasing levels of international collaboration on scholarly scientific articles in leading journals. From the article: '[M]ore than 35% of articles in leading journals are now the product of international collaboration. That is up from 25% 15 years ago — something the old regime and the new alike can celebrate.'" Note that the "old guard" are still firmly in the lead on these measures of scientific prowess, but the growth rate is higher in the newcomer states.

arshadk writes with this excerpt from the BBC about researchers at Oxford University who found that inducing a small current in a subject's parietal lobe boosted their capacity for numerical learning: "The current could not be felt, and had no measurable effect on other brain functions. As it was turned on, the volunteers tried to learn a puzzle which involved substituting numbers for symbols. Those given the current from right to left across the parietal lobe did significantly better when given, compared to those who were given no electrical stimulation. The direction of the current was important — those given stimulation running in the opposite direction, left to right, did markedly worse at these puzzles than those given no current, with their ability matching that of an average six-year-old. The effects were not short-lived, either. When the volunteers whose performance improved was re-tested six months later, the benefits appear to have persisted. There was no wider effect on general maths ability in either group, just on the ability to complete the puzzles learned as the current was applied."

Velcroman1 writes "On October 26, 2,000 Norwegians watched the sun set. The next time they'll see it rise? Sometime in February. Extended nighttime is an annual occurrence for the residents of Longyearbyen, Norway — Earth's northernmost town. Located at 78 degrees north latitude in the Arctic circle, Longyearbyen experiences a phenomenon called Polar Night, in which the town remains in perpetual darkness for four months each winter. To lighten up the seemingly endless night, Philips has started an experiment called 'Wake Up the Town.' And anyone who's complained about the brief daylight hours in winter will want to know how it works."
