Submission + - Scientists Explain How the Brain Cleans Itself (medicaldaily.com) 1

Submitted by Anonymous Coward
An anonymous reader writes: Every organ in the body has to expel waste somehow. Despite the brain's importance in the body, scientists were previously unclear as to how the brain flushed out its toxins, because it did not have a lymphatic system like other organs, which filters out waste. The previous theory stated the cerebrospinal fluid, in which the brain is encased, expelled junk, as waste floated through tissues and made its way onto the surface – but that seemed wildly inconvenient for the amount of waste that the brain must produce. Now, researchers have discovered a second, faster cleaning system on top of the cerebrospinal fluid, and it may shed some light on what happens during disorders that affect the brain.

Submission + - Curiosity survives brain transplant, prepares for first drive (engadget.com)

Submitted by alancronin
alancronin writes: If you thought your OTA update took too long, how about four days? That's how long the Curiosity "brain transplant" took, and is now finally complete. This now means that the main computers have switched over from landing mode, to surface mode — and thus we hope — meaning the rover's good to go. That said, it's still a painfully slow process, with Curiosity's wheels likely remaining steadfastly motionless for at least another week — and even then we're looking at a trip of just a few meters. When it comes to interplanetary travel, though, slow and steady definitely wins the race — in the meantime, you can soak up the view.

Submission + - Ask Slashdot: How to ensure data would survive a Carrington event 2

Submitted by kactusotp
kactusotp writes: I run a small indie game company and since source code is kind of our life blood, I'm pretty paranoid about backups. Every system has a local copy, servers run from a raid 5 nas, we have complete offsite backups, backup to keyrings/mobile phones, and cloud backups in other countries as well. With all the talk about solar flares and other such near extinction events lately, I've been wondering though, is it actually possible to store or protect data in such a way, that if such an event occurred, data survives and is recoverable in a useful form? Optical and magnetic media would probably be rendered useless by a large enough solar flare and storing source code/graphics in paper format would be impractical to recover, so Slashdot, short of building a Faraday cage 100 km below the surface of the moon, how could you protect data to survive a modern day Carrington event? http://www.abc.net.au/science/articles/2012/03/06/3446150.htm

"Severe Abnormalities" Found In Fukushima Butterflies 189

Posted by samzenpus from the birth-of-mothra dept.
Dupple writes "The collapse of the Fukushima Dai-ichi Nuclear Power Plant caused a massive release of radioactive materials to the environment. A prompt and reliable system for evaluating the biological impacts of this accident on animals has not been available. This study suggests the accident caused physiological and genetic damage to the pale grass blue Zizeeria maha, a common lycaenid butterfly in Japan. We collected the first-voltine adults in the Fukushima area in May 2011, some of which showed relatively mild abnormalities. The F1 offspring from the first-voltine females showed more severe abnormalities, which were inherited by the F2 generation. Adult butterflies collected in September 2011 showed more severe abnormalities than those collected in May. Similar abnormalities were experimentally reproduced in individuals from a non-contaminated area by external and internal low-dose exposures. We conclude that artificial radionuclides from the Fukushima Nuclear Power Plant caused physiological and genetic damage to this species."

Submission + - Survey of Human Centered Informatics (amazon.com)

Submitted by kodiaktau
kodiaktau writes: My exposure to HCI or Human Computer Interaction (now Human Centered Informatics) has been largely aged and limited to some brief early interaction with the Association of Computing Machinery. Since then I have been loosely following trends in usability but haven't really focused on the actual science behind the work we do on a day-to-day basis in creating user interfaces and using web applications. When I picked up this book I assumed it would be some unifying theory of HCI that would catch me up with where the science is today, but found it to be quite different.

In 113 pages, including the author biography, Yvonne Rogers winds a curious path through not only the theories behind HCI, but also a significant portion of time is spent giving some background in the history of the study. I was pleased to find that science is evolving and has spent a significant amount of time working with other social science disciplines as well as technical interaction. It was also interesting to see that like other social based disciplines there are many forks from the origin. I liked this book's style of simple presentation around theories. Most authors would trip over themselves trying to find long and complicated ways of explaining theory and purpose. This author is straight to the point and has practical examples for the different phases of the HCI theory evolution. In particular I really liked the way she included "...in a Nutshell" summaries of each theory. In a very small area she re-stated theory in an easy to digest manner. Don't get me wrong, this isn't a "For Dummies" kind of book, but the presentation is simple, elegant and well, usable.

The limited number of pages in the title may dissuade readers from purchasing, however this is not a case of more-is-better. I spent a lot of time reading this book in small chunks so I could completely understand each theory and how it evolved from previous models both inside the science and from other disciplines. While this book isn't for everyone I would certainly recommend this to someone moving into HCI studies, or for those who have interest in user interaction and classical theory. My biggest disappointment with this title was the quality of some diagrams supporting the theories. There is a lot of pixelation in some of the art and the fonts used in them can be a little hard to read. Really the publisher should have fixed those issues before going to print. As a survey of the body of knowledge I think this is really good. It is a little on pricey side at $35 for the amount of material, but the quality and uniqueness seems to be about right for the price.

Submission + - Brutal July heat a new U.S. record (cnn.com) 1

Submitted by gollum123
gollum123 writes: The July heat wave that wilted crops, shriveled rivers and fueled wildfires officially went into the books Wednesday as the hottest single month on record for the continental United States. The average temperature across the Lower 48 was 77.6 degrees Fahrenheit, 3.3 degrees above the 20th-century average, the National Oceanographic and Atmospheric Administration reported. That edged out the previous high mark, set in 1936, by two-tenths of a degree, NOAA said. n addition, the seven months of 2012 to date are the warmest of any year on record and were drier than average as well, NOAA said. U.S. forecasters started keeping records in 1895. And the past 12 months have been the warmest of any such period on record, topping a mark set between July 2011 and this past June. Every U.S. state except Washington experienced warmer-than-average temperatures, NOAA reported.

The robotic device blends soil sourced on-site with a binder and then sprays the mixture onto a surface. The soil solidifies as the machine works, allow it to create furniture, load-bearing walls and support-free sculptural shapes. The device runs on solar power, and unlike other 3D printers it has the ability to print in multiple directions on both the vertical and horizontal plane.

phrackwulf writes: In college I majored in materials science and now support myself as a contract engineer providing various technical services to a wide variety of companies. As I've gotten older, I've found myself more and more attracted to big data analytics and combinatoric and applied math because of the idea of using math to solve real world problems and a lifelong passion for mathematical logic. My question is this, what does someone in their mid thirties do to get admitted to a graduate program in applied mathematics? What undergraduate work should I consider doing first and what types of things would make me more marketable to a school with a highly competitive program?

Comment "Own" the music? (Score 1) 390

Doesn't it get absurdly expensive to "own" the music?

Oh wait, you meant own a copy of the music. Or is it own a license (non-transferable) to a single physical copy...well, there's fair use of course.

I am so glad no one has gotten to the point of trying to build business models around breathing.

Ruby, Clojure, Ceylon: Same Goal, Different Results 138

Posted by timothy from the ways-of-seeing dept.
snydeq writes "Charles Nutter, Rich Hickey, and Gavin King each discovered that 'simplicity' doesn't mean the same thing as they developed Ruby, Clojure, and Ceylon, respectively. 'Languages that are created with similar goals in mind may yield highly disparate final results, depending on how their communities understand those goals,' writes Andrew Oliver. 'At first, it surprised me that each language's creator directly or indirectly identified simplicity as his goal, as well as how differently the three creators and their languages' communities define what simplicity is. For Ruby, it is about a language that feels natural and gets out of your way to do what you want. For Clojure, it is about keeping the language itself simple. For Ceylon, it is a compromise between enabling the language to help, in King's words, "communicating algorithms to humans" and providing proper tooling support: the same general goal, three very different results.'"

Submission + - "Open Source Bach" project completed; score and recording now online (opengoldbergvariations.org) 1

Submitted by
rDouglass
rDouglass writes: "MuseScore, the open source music notation editor, and pianist Kimiko Ishizaka have released a new recording and digital edition of Bach's Goldberg Variations. The works are released under the Creative Commons Zero license to promote the broadest possible free use of the works. The score underwent two rounds of public peer review, drawing on processes normally applied to open source software. Furthermore, the demands of Bach's notational style drove significant advancements in the MuseScore open source project. The recording was made on a Bösendorfer 290 Imperial piano in the Teldex Studio of Berlin. Anne-Marie Sylvestre, a Canadian record producer, was inspired by the project and volunteered her time to edit and produce the recording. The project was funded by a successful Kickstarter campaign that was featured on Slashdot in March 2011."
