eBay puts Indiana Jones out of work

Harrison Ford on set as archaeologist Indiana JonesThe rise of eBay and similar online marketplace has been a death-knell for a number of industries and a boon for others… but not always in the way that people expected. Archaeologists the world over deplored the arrival of eBay, fearing it would make the trade in rare looted antiquities even harder to control. It turns out, however, that exactly the opposite has occured:

Our greatest fear was that the Internet would democratize antiquities trafficking and lead to widespread looting. This seemed a logical outcome of a system in which anyone could open up an eBay site and sell artifacts dug up by locals anywhere in the world. We feared that an unorganized but massive looting campaign was about to begin, with everything from potsherds to pieces of the Great Wall on the auction block for a few dollars. But a very curious thing has happened. It appears that electronic buying and selling has actually hurt the antiquities trade.

How is it possible? The short answer is that many of the primary “producers” of the objects have shifted from looting sites to faking antiquities. I’ve been tracking eBay antiquities for years now, and from what I can tell, this shift began around 2000, about five years after eBay was established.

Not only that, it appears to have encouraged a growing market for cheap imitations of antiquities:

The economics of these transactions are quite simple. Because the eBay phenomenon has substantially reduced total costs by eliminating middlemen, brick-and-mortar stores, high-priced dealers, and other marginal expenses, the local eBayers and craftsmen can make more money cranking out cheap fakes than they can by spending days or weeks digging around looking for the real thing. It is true that many former and potential looters lack the skills to make their own artifacts. But the value of their illicit digging decreases every time someone buys a “genuine” Moche pot for $35, plus shipping and handling. In other words, because the low-end antiquities market has been flooded with fakes that people buy for a fraction of what a genuine object would cost, the value of the real artifacts has gone down as well, making old-fashioned looting less lucrative. The value of real antiquities is also impacted by the increased risk that the object for sale is a fake. The likelihood of reselling an authentic artifact for more money is diminished each year as more fakes are produced.

Good news for the defenders of history. Of course, the game will change again once we have widespread fabrication technology; will there be a point at which fakes and close copies become so ubiquitous and easily available that the kudos value of the real thing becomes too appealing to resist for those with a bulging wallet and something to prove?

Cyberpunk style arrives: living jewelry and electronic tattoos

As a person seemingly born with a missing coolness gene, a big part of the appeal of cyberpunk was its visual aesthetic – why stick to a baseline body when you can bolt stuff on to make it look more interesting? And while I’m getting too old to care much about impressing people with the way I look, it’s fun to see those technofashions slowly seeping out from the pages of much-loved novels and into reality.

Exhibit one: EpiSkin, described by its creator as jewellery which “extends biological identity by combining technology and design into a new decorative body surface. This project is an exploration into the decorative technological control over biology to create an artifact which is a hybrid of both.”

EpiSkin living jewellery

Cultured in a lab, this biological jewelry is made of epithelia cells which grow to create an artificial skin. The cells are grown into custom designed forms, controlled by the artist. The cells are incubated for a period of time, following which they are stained with a custom dye. The skin is then visibly sealed into a wearable object. The process in creating these pieces includes human tissue culturing as well as computer generated form on which the cells are cultured and then transplanted into adaptive jewelry. The jewelry is worn on the body, completing the relationship of biological cells mediated by technology.

Exhibit two: Bare, a skin-safe conductive ink

… that is applied directly onto the skin allowing the creation of custom electronic circuitry. This innovative material allows users to interact with electronics through gesture, movement, and touch. Bare can be applied with a brush, stamp or spray and is non-toxic and temporary. Application areas include dance, music, computer interfaces, communication and medical devices. Bare is an intuitive and non-invasive technology which will allow users to bridge the gap between electronics and the body.

By the time the children of my contemporaries start choosing their own fashions, there’s going to be some wild stuff to see on the mean streets of style. [EpiSkin story via PosthumanBlues; Bare Conductive Ink via Bruce Sterling]

A brief word on a new supermaterial

graphene-transistorGraphene: a material consisting of a sheet of carbon atoms one atom thick. Graphene was first identified only a few years ago, and has since been proferred for all sorts of uses, including ultracapacitors, spintronics, and now as a light source:

Microchips is just one of the material’s potential applications. Because of its single-atom thickness, pure graphene is transparent, and can be used to make transparent electrodes for light-based applications such as light-emitting diodes (LEDs) or improved solar cells.

It is also apparently very strong:

The mobility of electrons in graphene — a measure of how easily electrons can flow within it — is by far the highest of any known material. So is its strength, which is, pound for pound, 200 times that of steel.

The problem is to find a way to mass-manufacture it:

The trick that enabled the first demonstrations of the existence of graphene as a real separate material came when researchers at the University of Manchester applied sticky tape to a block of graphite and then carefully peeled off tiny fragments of graphene and placed them on the smooth surface of another material.

“They don’t care if they go to a lot of effort to make five tiny pieces, they can study those for years.” But when it comes to possible commercial applications, it’s essential to find ways of producing the material in greater quantities.

Biofueled car might have been a senseless waste of chocolate

chocolate-carIt’s not quite the “chocolate-fueled car” that the headline from the indispensable PhysOrg.com promises. What we have instead may be close enough — a car its makers claim can reach 145 miles per hour,

powered by waste from chocolate factories and made partly from plant fibers….

The steering wheel is made out of plant-based fibers derived from carrots and other root vegetables, and the seat is built of flax fibre and soybean oil foam. The body is also made of plant fibers….

Scientists at the University of Warwick say their car is the fastest to run on biofuels and also be made from biodegradable materials. It has been built to Formula 3 specifications about the car’s size, weight, and performance.

Why hasn’t mobile banking spread out from Africa?

Kenyan woman with mobile phoneIf there’s been one good thing to come out of the global financial shitstorm, it’s that all of a sudden we’re looking afresh at established institutions and questioning whether, actually, there aren’t much better ways we could be doing things.

Point in case: mobile peer-to-peer banking, which is going gangbusters in parts of Africa but has yet to make much of a splash beyond that continent. The Guardian‘s Victor Keegan takes a closer look, and wonders whether it might be the key to saving the UK’s continually beleagured, semi-nationalised and utterly mismanaged postal service:

If you want to see pioneering experiments in banking you will have to go to a surprising place – Africa. And the question is, why can’t we do the same here? If the Post Office is looking for a new role, it need look no farther. In Kenya, customers of M-Pesa can send money to each other from around the country in 14 seconds flat using their mobiles. In the UK it takes three days, thereby endowing the banks with a huge float of money in transit on which they can earn interest. In Kenya, people leave their money at a trusted outlet such as a shop or pharmacy, where it is loaded into their sim cards.

At a Forum Oxford future technologies conference at the weekend we were updated on the startling success of the operation. It is reckoned that 17% of the Kenyan population is on M-Pesa. As a result they don’t need to carry cash any more, as everything from a can of Coke to your funeral can be paid for by phone. It works because the cash is held centrally by the bank, thereby enabling transactions to take place at very fast speeds. The average transaction is $30 (£20) because people trust it to do big ticket items.

Of course, there is always PayPal (which offers a mobile-linked transfer system as well), but finding a business that will accept PayPal that isn’t internet based is a big challenge. So, why hasn’t the idea caught on in more developed nations? [image by whiteafrican]

Maybe it is because we are not used to the idea of technology transfer coming from poorer to richer nations that industrialised nations have been so slow to realise not only that Africa is leading the world in mobile banking, but that it has big lessons for us.

Call me cynical (O RLY?), but I suspect it has a lot more to do with the fact that banks have no need to sell their services to us in a manner that emphasises our convenience, because our lives are so inextricably entangled in their profit generation systems already. Just like a drug dealer, they like to keep you waiting so as to remind you whose bitch you are…
