GPUs Helping To Lower CT Scan Radiation 77

Posted by kdawson from the healthy-green-glow dept.
Gwmaw writes with news out of the University of California, San Diego, on the use of GPUs to process CT scan data. Faster processing of noisy data allows doctors to lower the total radiation dose needed for a scan. "A new approach to processing X-ray data could lower by a factor of ten or more the amount of radiation patients receive during cone beam CT scans... With only 20 to 40 total number of X-ray projections and 0.1 mAs per projection, the team achieved images clear enough for image-guided radiation therapy. The reconstruction time ranged from 77 to 130 seconds on an NVIDIA Tesla C1060 GPU card, depending on the number of projections — an estimated 100 times faster than similar iterative reconstruction approaches... Compared to the currently widely used scanning protocol of about 360 projections with 0.4 mAs per projection, [the researcher] says the new processing method resulted in 36 to 72 times less radiation exposure for patients."

Maybe it's just your observation bias. Did you control for that in your highly complex subjective calculations?

The concept of "women's intuition" is from about 100 years ago. If you're going to be sexist, at least update your buzzwords.

Tetris Clones Pulled From Android Market 396

Posted by Soulskill from the bad-news-bears dept.
sbrubblesman writes "The Tetris Company, LLC has notified Google to remove all Tetris clones from Android Market. I am one of the developers of FallingBlocks, a game with the same gameplay concepts as Tetris. I have received an email warning that my game was suspended from Android Market due to a violation of the Developer Content Policy. When I received the email, I already imagined that it had something to do with it being a Tetris clone, but besides having the same gameplay as Tetris, which I believe cannot be copyrighted, the game uses its own name, graphics and sounds. There's no reference to 'Tetris' in our game. I have emailed Google asking what is the reason for the application removal. Google promptly answered that The Tetris Company, LLC notified them under the DMCA (PDF) to remove various Tetris clones from Android Market. My app was removed together with 35 other Tetris clones. I checked online at various sources, and all of them say that there's no copyright on gameplay. There could be some sort of patent. But even if they had one, it would last 20 years, so it would have been over in 2005. It's a shame that The Tetris Company, LLC uses its power to stop developers from creating good and free games for Android users. Without resources for a legal fight, our application and many others will cease to exist, even knowing that they are legit. Users will be forced to buy the paid, official version, which is worse than many of the ones available for free on the market. Users from other countries, such as Brazil in my case, won't even be able to play the official Tetris, since Google Checkout doesn't exist in Brazil; you can't buy paid applications from Android Market in these countries."

Dwarf Planets Accumulate In Outer Solar System 93

Posted by kdawson from the potato-radius dept.
An anonymous reader tips a piece in Australian Geographic indicating that Pluto may be in for another demotion, as researchers work to define dwarf planets more exactly. "[Australian researchers] now argue that the radius which defines a dwarf planet should instead be from 200–300 km, depending on whether the object is made of ice or rock. They base their smaller radius on the limit at which objects naturally form a spherical rather than potato-like shape because of 'self-gravity.' Icy objects less than 200 km (or rocky objects less than 300 km) across are likely to be potato shapes, while objects larger than this are spherical. ... They call this limit the 'potato radius' ... [One researcher is quoted] 'I have no problem with there being hundreds of dwarf planets eventually.'"

Tremulous Switching To Xbox Live, Exclusively 43

Posted by timothy from the console-yourself dept.
An anonymous reader writes "Darklegion Development and Microsoft have apparently been working on a new version of Tremulous for the Xbox 360. Timbor, project founder and a main developer of Tremulous, said this in a recent announcement: 'What does this mean for you? You will now be able to play Tremulous on Xbox Live with thousands of other gamers, earning achievements and showing off your gaming skill. In the best interest of maintaining a steady and secure Tremulous playerbase, Tremulous is going to be exclusively available for Xbox Live. Existing infrastructure will no longer receive official support. Players who have already been playing for at least three months can apply for a €5/$7 coupon as a show of our appreciation of your enthusiasm so far! What does this mean for the community? Hopefully nothing! While the production of Tremulous switches from its current open source development to a closed source environment handled by the very capable and experienced Microsoft engineers, the efforts of the community will still be valued. In this collaboration we have made it very clear that the Tremulous community is very important to the game, and Microsoft agrees with us on this point. We are confident that this move will not stifle the creative output of the community.'"

DarkPlaces Dev Forest Hale Corrects Nexuiz GPL Stance 131

Posted by Soulskill from the two-sides-to-every-story dept.
Time Doctor writes "There has been a lot of information going around about Nexuiz, the GPL, and what the Nexuiz leadership has done. A new interview has gone up with DarkPlaces developer Forest Hale to set things straight. Quoting: 'The original plan was to contact every developer and relicense the Nexuiz 2.5.2 GPL gamecode sources for this title, to ensure authentic gameplay and return some important features to the community for the benefit of everyone. However this gamecode re-licensing attempt did not go well; with the former developers making claims of violations there was no choice but to re-implement the gamecode from scratch on non-GPL sources. As a result there will be no ongoing code contributions back to the community, and the gameplay may differ more than originally planned. This is a very unfortunate outcome but has no significant impact on development. To make this perfectly clear – the game is being reimplemented from scratch; all they share is a name.'"

The Unsung Heroes of PC Gaming History 325

Posted by Soulskill from the setting-the-standard dept.
An anonymous reader writes "The history of PC gaming is littered with many well-known and highly regarded titles, but what about the titles you mightn't have heard of? This list of the top games in the history of the PC includes the usual suspects, such as Half-Life and Doom, but also some often overlooked PC games including such classics as Elite, the space trading RPG developed in 1984 by two college friends from Cambridge for the Acorn and BB Micro systems. The game used a truly elegant programming hack to create over 200 different worlds to explore while using 32kb of memory, all with 3D wireframes. Also in the list is Robot War, which required players to actually code the participants, and one of the first online multiplayer RPGs, Neverwinter Nights, which introduced many of the developer and user behaviors, such as custom guilds, that have made modern RPGs so popular." What's your favorite classic game that always gets overlooked in these kinds of lists? My vote goes for Star Control 2.

Planned Nuclear Reactors Will Destroy Atomic Waste 344

Posted by Soulskill from the but-where-will-we-get-our-superheroes dept.
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!"

Aussie Gamers Dress As Zombies To Raise R18+ Awareness 85

Posted by samzenpus from the know-we'll-get-to-common-ground-somehow dept.
swandives writes "Australian gamers will dress as zombies to raise awareness about the lack of an R18+ rating for video games in the country. The protest will begin at Hyde Park Fountain on March 27 and lumber through Sydney, raising awareness of the need for a higher classification rating and hopefully causing a bit of havoc at the same time! Computerworld Australia has pictures of previous zombie protests in the lead-up to the event. Australia has a long history of lobbying for an R18+ games classification but, even after a decade, video games are banned from sale if they exceed the maximum M15+ classification. So far, the list of banned titles includes 7 Sins, Risen, Left 4 Dead 2 and Dark Sector. Others, like Alien vs. Predator, were initially banned but appealed the rating and are now MA15+."

The Problems With Video Game Voice Acting 251

Posted by Soulskill from the who-called-in-de-fleet dept.
The Guardian's Games blog explores the tendency of modern video games to suffer from poor voice acting, a flaw made all the more glaring by increasingly precise and impressive graphics. Quoting: "Due to the interactive nature of games, actors can't be given a standard film script from which they're able to gauge the throughline of their character and a feel for the dramatic development of the narrative. Instead, lines of dialogue need to be isolated into chunks so they can be accessed and triggered within the game in line with the actions of each individual player. Consequently, the performer will usually be presented with a spreadsheet jammed with hundreds of single lines of dialogue, with little sense of context or interaction. ... But according to David Sobolov, one of the most experienced videogame voice actors in the world (just check out his website), the significant time pressures mean that close, in-depth direction is not always possible. 'Often, there's a need to record a great number of lines, so to keep the session moving, once we've established the tone of the character we're performing, the director will silently direct us using the spreadsheet on the screen by simply moving the cursor down the page to indicate if he/she liked what we did. Or they'll make up a code, like typing an 'x' to ask us to give them another take.' It sounds, in effect, like a sort of acting battery farm, a grinding, dehumanizing production line of disembodied phrases, delivered for hours on end. Hardly conducive to Oscar-winning performances."

Study Finds That Video Games Hinder Learning In Young Boys 278

Posted by Soulskill from the fun-activities-distract-from-studies,-film-at-11 dept.
dcollins writes "Researchers at Denison University in Ohio have shown that giving PlayStations to young boys leads to slower progress in reading and writing skills. Quoting: 'The study is the first controlled trial to look at the effects of playing video games on learning in young boys. That is to say, the findings aren't based on survey data of kids' game habits, but instead on a specific group of children that were randomly assigned to receive a PlayStation or not ... Those with PlayStations also spent less time engaged in educational activities after school and showed less advancement in their reading and writing skills over time than the control group, according to tests taken by the kids. While the game-system owners didn't show significant behavioral problems, their teachers did report delays in learning academic skills, including writing and spelling.'"
