Ars Technica: "Humans began making paint and glue at roughly the same time with the same tools. Evidence from a cave in eastern Ethiopia has revealed something extraordinary about the origins of symbolic thought among humans." [more inside]
As part of our special focus on innovation in Africa, we have developed a list of 40 remarkable African innovators. Actually, it’s more like 47 but we counted teams as one. Our decision to celebrate these idea creators and solution providers stems from our belief that the true wealth of Africa is not buried under its soil, but in the brains of its best minds. This list is a testament to that belief.
This is Suame Magazine. A vast, open-air industrial district in Kumasi, Ghana’s second largest city. Here, 200,000 skilled workers manufacture everything from bolts to tanker trucks by hand. A million dollars passes through the factories and workshops here every day, and it’s the place where most of the country’s laborers learn their trades: the heart of Ghana’s informal economy.Photos and Story
The Forces Of The Next 30 Years - SF author and Mefi's Own Charles Stross talks to students at Olin College about sci-fi, fiction, speculation, the limits of computation, thermodynamics, Moore's Law, the history of travel, employment, automation, free trade, demographics, the developing world, privacy, and climate change in trying to answer the question What Does The World Of 2043 Look Like?

DJ Focus couldn't wait to get back to Sierra Leone. AKA Kelvin Doe, this young man makes beautiful, functional and very useful electronic devices out of trash found in his native Sierra Leone. It's not clear whether he or M.I.T. was more impressed after his visit there.
When it comes to railways, the British are famous for their colonial legacy of one of the world's most extensive railway networks built across then British India but their lesser known and far grander vision was the Cape to Cairo railway network intended to stretch across the sea of colonial pink on the African continent. Left incomplete due to politics and geography, most of it is still almost as it was built in its day. [more inside]
Necessity Is the Mother of Invention. (NY Times, reg. req.) Amy Smith teaches MIT students about the politics of delivering technology to poor nations and the nitty-gritty of mechanical engineering and helped start the IDEAS competition; she herself designed (among other things) a screenless hammer mill suited to third-world conditions and using "materials available to a blacksmith in Senegal."
Smith's entire life is like one of her inventions, portable and off the grid. At 41, she has no kids, no car, no retirement plan and no desire for a Ph.D. Her official title: instructor. ''I'm doing exactly what I want to be doing. Why would I spend six years to get a Ph.D. to be in the position I'm in now, but with a title after my name? M.I.T. loves that I'm doing this work. The support is there. So I don't worry.''...A rare optimistic story for these downbeat times.
Likewise, the inventors who most inspire her will never strike it rich. ''There are geniuses in Africa, but they're not getting the press,'' she says. She gushes about Mohammed Bah Abba, a Nigerian teacher who came up with the pot-within-a-pot system. With nothing more than a big terra-cotta bowl, a little pot, some sand and water, Abba created a refrigerator -- the rig uses evaporation rather than electricity to keep vegetables cool. Innovations that target the poorest of the poor don't have to be complicated to make a big difference. The best solution is sometimes the most obvious.
