A new study suggests that cost-effective galactic radio transmissions would be at higher frequencies than SETI projects traditionally monitor, and ET's attempts to make contact would be only few and far between. "If ET was building cost-effective beacons, would our searches have detected them? The answer turns out to be no," says James Benford, president of the company Microwave Sciences in Lafayette, California.

"In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

During the past 15 years, the World Wide Web has created remarkable new methods for harnessing the creativity of people in groups, and in the process has created powerful business models that are reshaping our economy. As the Web has undermined old media and software companies, it has demonstrated the enormous power of a new approach, often referred to as Web 2.0. In a nutshell: the secret to the success of bellwethers like Google, Amazon, eBay, Craigslist, Wikipedia, Facebook, and Twitter is that each of these sites, in its own way, has learned to harness the power of its users to add value to-no, more than that, to co-create-its offerings.
The future of metabolic engineering: Designer molecules, cells and microorganisms - 0 views
-
ScienceDaily (Dec. 3, 2010) - Will we one day design and create molecules, cells and microorganisms that produce specific chemical products from simple, readily-available, inexpensive starting materials? Will the synthetic organic chemistry now used to produce pharmaceutical drugs, plastics and a host of other products eventually be surpassed by metabolic engineering as the mainstay of our chemical industries? Yes, according to Jay Keasling, chemical engineer and one of the world's foremost practitioners of metabolic engineering.

Technology Review: Keeping Tabs - 1 views

But the tab as an information technology metaphor is everywhere in use. And whether our tabs are cardboard extensions or digital projections, they all date to an invention little more than a hundred years old. The original tab signaled an information storage revolution and helped enable everything from management consulting to electronic data processing.

Apparently, if Facebook wanted to repair its reputation, all it had to do was seem like it was helping to topple an authoritarian regime. Now that the U.S. media is loudly pushing the idea that social media can change Egypt-and next, the world!-it makes Mark Zuckerberg's tendency to monetize every aspect of our online lives seem less important.
The World's Technological Capacity to Store, Communicate, and Compute Information | Kur... - 0 views

A study appearing Feb. 10 in Science Express calculates the world's total technological capacity to store, communicate and compute information, part of a Special Online Collection: Dealing with Data. The study by the USC Annenberg School for Communication & Journalism estimates that in 2007, humankind was able to store 2.9 × 1020 optimally compressed bytes, communicate almost 2 × 1021 bytes, and carry out 6.4 × 1018 instructions per second on general-purpose computers. General-purpose computing capacity grew at an annual rate of 58%. The world's capacity for bidirectional telecommunication grew at 28% per year, closely followed by the increase in globally stored information (23%). Humankind's capacity for unidirectional information diffusion through broadcasting channels has experienced comparatively modest annual growth (6%). Telecommunication has been dominated by digital technologies since 1990 (99.9% in digital format in 2007), and the majority of our technological memory has been in digital format since the early 2000s (94% digital in 2007).

RepRap is a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap can print those parts, RepRap is a self-replicating machine - one that anyone can build given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too.Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. Our community portal and New Development pages have more information on how to get involved. Use the links below and on the left to explore the site contents. You'll find some content translated into other languages.RepRap is described in the video on the right.
Technology: Necessary but Insufficient for Human Survival | Thinkahol's Blog - 0 views

In the context of technology the only way out is through. Global society is dependent on artificially inflated energy resources-i.e. oil-that are directly leading us toward total collapse. Technology is being used to most efficiently maximize wealth of the largest corporate conglomerates at the expense of the social fabric and a living environment. The biosphere is in fact collapsing. The technology exists to solve our technical problems but the solutions do not seem like they will be effectively put to use. The power structures concentrating money off the status quo are too entrenched. Each human is called on to become more aware.
