+ - 3D Bioprinters Could Make Enhanced, Electricity-Generating 'Superorgans'

Submitted by meghan elizabeth
meghan elizabeth (3689911) writes "Why stop at just mimicking biology when you can biomanufacture technologically improved humans? 3D-printed enhanced "superorgans"—or artificial ones that don’t exist in nature—could be engineered to perform specific functions beyond what exists in nature, like treating disease. Already, a bioprinted artificial pancreas that can regulate glucose levels in diabetes patients is being developed. Bioprinting could also be used to create an enhanced organ that can generate electricity to power electronic implants, like pacemakers."

+ - Wordpress: Is Light Pollution the Easiest Environmental Problem to Fix?->

Submitted by janedffy
janedffy (2991141) writes "Not so terribly long ago, people everywhere experienced nights so black that even the Milky Way could cast shadows on the earth. According to some estimates, around 80 percent of people now live under night skies so polluted by artificial light that they’ve never seen the Milky Way at all.

As with many aspects of modern life, light pollution represents both a triumph of technology and a minor disaster. Along with increased safety, convenience and economic benefits, an artificially lit world brings heath problems, environmental degradation and another layer of inefficient energy consumption. It also disrupts a fundamental relationship that has evolved between humans and the natural world. Far from the province just of goblins and bandits, historians such as A. Roger Ekrich have noted how darkness influenced cultural and social practices. The territory of intimacy and imagination, night can also carve out a refuge from the never-ending responsibilities of the day.

This notion, that night is an integral, and profound, part of the human experience, not merely a few inconvenient hours away from the sun, underpins author Paul Bogard’s impassioned defense The End of Night: Searching for Darkness in an Age of Artificial Light.

In the book, Bogard, who teaches creative nonfiction and environmental writing at James Madison University, and often lectures on the subject of light pollution, charts a geography of night across Western Europe and North America in which the majority of their residents under 40 have been raised in a world without “real night.” For Bogard, who spent his childhood summers in the dark nights at the edge of a Minnesota lake, the pace at which we’re relighting the world has pushed us to the cusp of an incalculable loss. Unchecked, the damage renders our world not just poorer, but also smaller. Throughout human history, for instance, the night sky has offered a taste of transcendence with its awe-inspiring beauty. “And in this beauty,” Bogard writes in the introduction to The End of Night, “the overwhelming size of the universe has seemed less ominous, Earth’s own beauty more incredible. If indeed the numbers and distances of the night sky are so large that they become nearly meaningless, then let us find the meaning under our feet.”

In the edited conversation below, the author discusses the dangers of staying up late with your iPad and the $2.2 billion we could recoup overnight.

A PBS piece on light pollution talks about how, after a huge power outage struck LA in the 1990s, Angelenos were reportedly so freaked out by the appearance of “strange clouds” hovering overhead that they called 911—evidently that was the first time most of them had ever gotten a glimpse of the Milky Way. At this point, what relationship do you think most modern Americans have to the night sky?

I remember recently being in Times Square, and there was so much light that it just felt like we were in a domed stadium almost, looking up at something totally artificial above us. That is obviously the extreme of the situation, but I think that when most Americans are living now in cities and suburbs where they’re getting anywhere from two dozen to four dozen stars instead of 2,500, which is the number you could see on a normal night with no light pollution, it’s almost like why bother? Why have a relationship? I don’t know if most people even look up and notice the stars. And certainly way, way back, when a night sky was something that would tell you stories about your life, we’re way beyond that.

I have very good friends in New Mexico, and I was just out at one of the pueblos there, like an hour from Albuquerque. I said to our guide, it must be amazing here at night, and he said, yeah it is, and I asked, do you have stories associated with the constellations for example? He said, yeah, we have a whole mythology filled with stories about how to live and what a good life is and all that. Human culture in America is totally disconnected from that now.

Your book incorporates a number of literary quotes, as well as references to artists and thinkers like Van Gogh and Thoreau. You seem to be drawing an implicit connection between darkness and the creative impulse.

I was just working on an essay where I was talking about the intangible value of darkness. At least a significant part of its value is these intangibles, like we were just talking in terms of mythology and metaphorical darkness, and I wrote something like, “Darkness is always a part of creation, every artist knows that.” Every artist has had that experience where you’re just like, oh my god, I don’t know what to do next, what’s the next line? What should I paint here? That’s that darkness. It’s not being able to see; it’s not obvious; it’s not lit up."

4-Billion-Pixel Panorama View From Curiosity Rover 101

from the take-a-look dept.
SternisheFan points out that there is a great new panorama made from shots from the Curiosity Rover. "Sweep your gaze around Gale Crater on Mars, where NASA's Curiosity rover is currently exploring, with this 4-billion-pixel panorama stitched together from 295 images. ...The entire image stretches 90,000 by 45,000 pixels and uses pictures taken by the rover's two MastCams. The best way to enjoy it is to go into fullscreen mode and slowly soak up the scenery — from the distant high edges of the crater to the enormous and looming Mount Sharp, the rover's eventual destination."

Google Pledges Not To Sue Any Open Source Projects Using Their Patents 153

Posted by Unknown Lamer
from the now-and-forever dept.
sfcrazy writes "Google has announced the Open Patent Non-Assertion (OPN) Pledge. In the pledge Google says that they will not sue any user, distributor, or developer of Open Source software on specified patents, unless first attacked. Under this pledge, Google is starting off with 10 patents relating to MapReduce, a computing model for processing large data sets first developed at Google. Google says that over time they intend to expand the set of Google's patents covered by the pledge to other technologies." This is in addition to the Open Invention Network, and their general work toward reforming the patent system. The patents covered in the OPN will be free to use in Free/Open Source software for the life of the patent, even if Google should transfer ownership to another party. Read the text of the pledge. It appears that interaction with non-copyleft licenses (MIT/BSD/Apache) is a bit weird: if you create a non-free fork it appears you are no longer covered under the pledge.

When Your Data Absolutely, Positively has to be Destroyed (Video) 295

Posted by Roblimo
from the it's-all-about-the-magnetism dept.
Here's a corporate motto for you: "Destroying data since 1959." Timothy ran into a company called Garner Products (which doesn't use that motto as far as we know), at a security conference. While most exhibitors were busily preserving or encrypting data one way or another, Garner was not only destroying data but delighting in it. And yes, they've really been doing this since 1959; they started out degaussing broadcast cartridges so broadcasters could re-use them without worrying about old cue tones creeping into new recordings. Now, you might ask, "Instead of spending $9,000 or more to render hard drives useless, couldn't you just use a $24 sledge hammer? And have the fun of destroying something physical as a free bonus?" Yes, you could. You'd get healthy exercise as well, and if you only wanted to destroy the data on the hard drives, so what? New drives are cheap these days. But some government agencies and financial institutions require degaussing before the physical destruction (and Garner has machines that do physical destruction, too -- which is how they deal with SSDs). Garner Products President Ron Stofan says in the interview that their destruction process is more certain than shooting a hard drive with a .45. But neither he nor Tim demonstrated a shooting vs. degaussing test for us, so we remain skeptical.

+ - WebGL flaw leaves GPU exposed to hackers

Submitted by recoiledsnake
recoiledsnake (879048) writes "Google spent a lot of time yesterday talking up WebGL, but UK security firm Context seems to think users should disable the feature because it poses a serious security threat, and the US Computer Emergency Readiness Team (CERT) is encouraging people to heed that advice. According to Context, a malicious site could pass code directly to a computer's GPU and trigger a denial of service attack or simply crash the machine. Ne'er-do-wells could also use WebGL and the Canvas element to pull image data from another domain, which could then be used as part of a more elaborate attack. Khronos, the group that organizes the standard, responded by pointing out that there is an extension available to graphics card manufacturers that can detect and protect against DoS attacks, but it did little to satisfy Context — the firm argues that inherent flaws in the design of WebGL make it very difficult to secure."

Amazon EC2 Enables Cheap Brute-Force Attacks 212

Posted by timothy
from the this-gun-for-hire dept.
snydeq writes "German white-hat hacker Thomas Roth claims he can crack WPA-PSK-protected networks in six minutes using Amazon EC2 compute power — an attack that would cost him $1.68. The key? Amazon's new cluster GPU instances. 'GPUs are (depending on the algorithm and the implementation) some hundred times faster compared to standard quad-core CPUs when it comes to brute forcing SHA-1 and MD,' Roth explained. GPU-assisted servers were previously available only in supercomputers and not to the public at large, according to Roth; that's changed with EC2. Among the questions Roth's research raises is, what role should Amazon and other public-cloud service providers play in preventing customers from using their services to commit crimes?"
