University of Athens prints polymer circuits with lasers, speeds us towards lowcost electronics

The dream of ubiquitous technology revolves around cheaper materials, and polymer circuits could help make the dream a reality… if the solvents used to produce the circuits didn’t cause more problems than they cured, that is. The National Technical University of Athens has developed a more exacting technique that, like most good things in science, solves the crisis with lasers. The approach fires a laser at a polymer layer (covered by quartz) to throw some of that polymer on to a receiving layer; by moving the two layers, the scientists can print virtually any 2D circuit without resorting to potentially damaging chemicals. Any leftover worries center mostly around risks of changing the chemical composition as well as the usual need to develop a reliable form of mass production. Any long-term success with laser-printed polymers, however, could lead to more affordable technology as well as more instances of flexible and wearable gear — there might not be much of a downside to ditching the circuit status quo.

From Ars Technica: Taliban fails to BCC an e-mail, reveals its entire PR mailing list

An apparent slip of the hand by a Taliban spokesperson has revealed the members of the group’s mailing list, according to a report Friday from ABC News. The 400 e-mail addresses include many journalists, but also a few members of government as well as “academics and activists.”

The Taliban regularly sends e-mail blasts with press releases highlighting its latest activities, usually from the e-mail account of spokesperson Qari Yousuf Ahmedi. But this time, the press release Ahmedi intended to send was forwarded from the account of another spokesperson, Zabihullah Mujahid. Ahmedi forwarded the e-mail on to the mailing list, but CC’d all 400 members, rather than BCC’ing them, so the full list of e-mail addresses was laid bare to all who received it.

According to ABC News, the list included “a provincial governor, an Afghan legislator” and an “Afghan consultative committee.” We can only imagine the chain of reply-alls that followed, but we’re certain it’s the stuff of nightmares.
