MIT's AI can identify breast cancer risk as reliably as a radiologist
Breast cancer affects one in eight women in the US. There are multiple factors involved in developing the disease, but one issue is dense breast tissue. Some 40 percent of US women have dense breast tissue, which alone increases the risk of breast cancer, and can make mammogram screening more difficult. Now, researchers from MIT and Massachusetts General Hospital (MGH) have developed an automated model that assesses dense breast tissue in mammograms as reliably as expert radiologists.
Flying plasmonic lens system could lead to denser chips / disks
Last we heard, IBM was busy extending optical lithography down to 30-nanometers in order to keep Moore's Law intact, and some two years later, the process is still being honed by engineers at the University of California, Berkeley. Reportedly, gurus there with IQs far greater than ours have developed a new patterning technique (plasmonic nanolithography) that could make "current microprocessors more than 10 times smaller, but far more powerful." Additionally, professor Xiang Zhang asserts that this same technology could eventually "lead to ultra-high density disks that could hold 10 to 100 times more data than disks today." The secret to the madness is a flying plasmonic head, which is compared to the arm and stylus of an LP turntable; the setup enables researchers to "create line patterns only 80-nanometers wide at speeds up to 12-meters per second, with the potential for higher resolution detail in the near future." In layman's terms? That CPU you purchased last month will, in fact, be old hat in due time.[Via Slashdot]
A look at the geography of WoW from Interesting '08
This is just beautiful, from the title ("Brave Noob World") to the idea -- a geographical survey of Azeroth. James Wallis, the director of Hogshead Publishing, gave this presentation at an "unconference" called Interesting '08, in which he tried to do a survey of Azeroth, in the same way that Tobold did -- by walking from one end to the other. And he discovers that Azeroth is pretty small and pretty dense -- it's about 12km across, according to him (I really like his comparison image of the Death Star), and using a Female Tauren, he even comes up with the force of gravity, which is about equal to Earth -- about 1g. Which makes sense; Blizzard would want the virtual world to feel the same as our world, no matter how big it is.There's a problem with that, though -- if you have a small planet with the same gravity as a much larger planet, the only answer is that the mass of the planet is much more dense. And when you get a really small, densely packed mass, you start to mess around with the flow of time. So Wallis actually ends up explaining one of the more annoying features of Azeroth with actual science. Very nice.It's definitely a fun example of looking for more in this MMO than Blizzard probably put there, but Wallis covers it with enough zest and logic that it works, strangely. Now if he could only explain the weather...[via Massively]Update: Looks like the video got pulled. It's been stowed after the break, just in case it comes back.
Seagate crams 250GB on a single Barracuda platter
Just a day after Hitachi and Philips boasted about its newest external 1TB offerings, Seagate is up on its own soap box clamoring over the "industry's first 250GB-per-disc, 3.5-inch disc drive." Touting the second-generation of perpendicular magnetic recording technology, the newest Barracuda 7200.10 stretches areal density limits by stuffing 180Gb per square inch, and also manages to "set new benchmarks" for power consumption, acoustics, and performance. The drives will feature a 3Gbps SATA interface and should pop up in future external models, but for now you can probably grab one in a retail box as Seagate has reportedly achieved worldwide volume deployments.[Via TGDaily]
Researchers churn out "world's densest" memory circuit
Undoubtedly, there's been quite a few chips claiming to hold some sort of "world's smallest" title, but a team of researchers have crafted what they call the "most dense computer memory circuit ever fabricated," capable of "storing around 2,000 words in a unit the size of a white blood cell." Scientists at Caltech and UCLA put their proximity differences behind them for a bit to develop a 160-kilobit memory cell that purportedly has a record-setting density of "100 gigabits per square centimeter." The bantam chip is capable of holding a document the size of the US Declaration of Independence with room leftover for a few quarterly reports (or slow jams), but Caltech chemistry professor James Heath doubts that we'll see it in mainstream action anytime soon. Still, the team isn't backing down from its discovery, and hopes to see this manufactured and placed into laptops in the coming years.[Via Slashdot]
