Reality mining: what your phone knows about you

mobile phone close-up The next big frontier for the software and web corporations is in your pocket – your mobile phone. But have you ever wondered why exactly the search giants like Yahoo and Google are so keen to get access to your handset? Sandy Pentland, an MIT researcher, explains in an interview at Technology Review:

“It knows where you are, and this is obviously sort of useful. But the generalization is that maybe it can know lots of things about you. Take your Facebook friends as an example. The phone could know which ones you socialize with in person, which ones are your work friends, and which friends you’ve never seen in your life. That’s an interesting distinction, and reality mining can make it automatic. It’s about making the “dumb” information-technology infrastructure know something about your social life. All this sort-of Web 2.0 stuff is nice, but you have to type stuff in.”

Quite. But as Nicholas Carr points out, that’s not quite as utopian as it might initially seem:

“… it’s easy to see the vast commercial value of automatically harvesting a continuous stream of data on a person’s location, activities, relationships, and social roles and using it to personalize services and advertisements or, in the extreme, manipulate behavior for profit-making ends.”

Well, it’s not like we’re unused to having our behaviour analysed and manipulated for commercial purposes … or to the idea that external agencies can spy on us by subverting our gadgets. But the point is that technologies in their default states are making it much easier – rather than rejecting Big Brother, have we instead slipped him into our back pocket? [Image by Milica Sekulic]

Stanford creates nanowire batteries with 10 times current charge

Nanowires are an exciting way to dramatically increase efficiency in exisiting silicon tech

Lithium-ion batteries, such as those used in your laptop, mobile phone or hybrid car, are extremely important in today’s world but are limited by the amount of lithium ions that the typically carbon anode can hold. Stanford announced this week they’ve developed a new method that can increase the amount of charge held by as much as 10 times.

 The new battery uses what is perhaps the technology of the next ten years – nanowires.  At large scale, the swelling of the lithium ions when they absorb positive charge breaks the structure of the silicon holding them. The researches instead used a mesh of microscopic silicon nanowires that bend and swell under the pressure but do not break. The researcher, Yi Cui, said:

Manufacturing the nanowire batteries would require “one or two different steps, but the process can certainly be scaled up,” he added. “It’s a well understood process.”

 I’ll look forward to my laptop with 25 hour battery life in a few years, then.

Kim Stanley Robinson interviewed

Kim_Stanley_Robinson BLDGBLOG has an excellent in-depth interview with Kim Stanley Robinson, in which he discusses his attempts to redefine utopias, the ideological bankruptcy of primitivism, how rational design in architecture and technology is one of the crucial keys to surmounting the problems presented by our changing environment, and much more.

A brilliant interview with a brilliant thinker … and hosted on a brilliant blog. You may think you’re not really interested in architecture, but I think an exploration of BLDGBLOG‘s archive would prove you wrong. Go read. [Image from Wikipedia]

Postpone shuttle’s retirement?

That’s what one politician wants, saying NASA should keep flying the shuttle to avoid depending on Russia to fly astronauts up.

That could be a disaster, much better to take that average cost of $450 million per shuttle launch and offer $450 billion to the first private company to launch someone to the space station by, say 2011.

Or better yet, for eye-catchiness, take the cost of 2 shuttle launches and round up slightly. $1 billion ought to turn heads, don’t you think?

Live longer, die suddenly – the double-edged sword of longevity drugs

CGI drug capsules Everything comes with a price. Research in lab animals suggests that drugs designed to rejuvenate mitochondria (the “power generator” component of living cells) could fend off many of the diseases we associate with ageing and senescence, like Alzheimer’s, cancer, heart disease and so forth. The pay-off? It appears that when death finally does arrive, it does so with little or no warning, and seemingly no reason. [Image by Rodrigo Senna]

Personally, I’d consider that a fair trade – I’m less scared of death itself than I am of dying, if you see what I mean. But is death itself unconquerable, or is it just the next hurdle in line?
