The opening of Randy Rieland’s a Smithsonian post about MIT’s Skylar Tibbits, who aims to one-up 3D printing before it even becomes popularized:

“These days, 3D printing seems to be at the core of most new new research ventures, whether it’s developing ways to print entire meals or recreating facial features to repair a patient’s face.

But Skylar Tibbits wants to up the ante: He’s hoping 4D printing will be the thing of the not-so-far future.

The name for his concept, Tibbits admits, was a bit lighthearted at first. At the Massachusetts Institute of Technology, Tibbits and researchers from the firms Stratasys and Autodesk Inc were trying to come up with a way of describing the objects they were creating on 3D printers—objects that not only could be printed, but thanks to geometric code, could also later change shape and transform on their own.

The name stuck, and now the process they developed—which turns code into ‘smart objects’ that can self-assemble or change shape when confronted with a change in its environment—could very well pop up in a number of industries, from construction to athletic wear.”

Excerpts from smart posts on two blogs at Smithsonian, one about the tortured history of Los Angeles public transportation and the other about the future of job interviews.

From Matt Novak’sNobody Walks in L.A.“:

“In 1926 there was a big push to build over 50 miles of elevated railway in Los Angeles. The city’s low density made many skeptical that Los Angeles could ever support public transit solutions to its transportation woes in the 20th century. The local newspapers campaigned heavily against elevated railways downtown, even going so far as to send reporters to Chicago and Boston to get quotes critical of those cities’ elevated railways. L.A.’s low density was a direct result of the city’s most drastic growth occurring in the 1910s and ‘20s when automobiles were allowing people to spread out and build homes in far flung suburbs and not be tied to public transit to reach the commercial and retail hub of downtown.

As strange as it may seem today, the automobile was seen by many as the progressive solution to the transportation problems of Los Angeles in the 1920s. The privately owned rail companies were inflating their costs and making it impossible for the city to buy them out. Angelenos were reluctant to to subsidize private rail, despite their gripes with service. Meanwhile, both the city and the state continued to invest heavily in freeways. In 1936 Fortune magazine reported on what they called rail’s obsolescence.

Though the city’s growth stalled somewhat during the Great Depression it picked right back up again during World War II. People were again moving to the city in droves looking for work in this artificial port town that was fueling the war effort on the west coast. But at the end of the war the prospects for mass transit in L.A. were looking as grim as ever.”

From Randy Rieland’s “How Big Data Will Mean the End of Job Interviews“:

“Consider the findings of Evolv, a San Francisco company that’s making a name for itself through its data-driven insights. It contends, for instance, that people who fill out online job applications using a browser that they installed themselves on their PCs, such as Chrome or Firefox, perform their jobs better and change jobs less often. You might speculate that this is because the kind of person who downloads a browser other than the one that came with his or her computer, is more proactive, more resourceful.

But Evolv doesn’t speculate. It simply points out that this is what data from more than 30,000 employees strongly suggests. There’s nothing anecdotal about it; it’s based on info gleaned from ten of thousands of workers. And that’s what gives it weight.

‘The heart of science is measurement,’ Erik Brynjolfsson, of the Sloan School of Management at M.I.T., pointed out in a recent New York Times article on what’s become known as work-force science. ‘We’re seeing a revolution in measurement, and it will revolutionize organizational economics and personnel economics.'”

From “Patient, Heal Thyself,” Randy Rieland’s new post at Smithsonian, a passage about the hopes for duplicating regenerative medicine in humans which is exhibited in a particular type of mouse:

“Mammals scar after they tear their skin. But not the spiny mouse. It can lose more than 50 percent of its skin and then grow a near perfect replacement, including new hair. Its ears are even more magical. When scientists drilled holes in them, the mice were able to not only grow more skin, but also new glands, hair follicles and cartilage.

And that’s what really excites researchers in human regenerative medicine, a fast-emerging field built around finding ways to boost the body’s ability to heal itself. As amazingly sophisticated as medicine has become, treatment of most diseases still focuses largely on managing symptoms–insulin shots to keep diabetes in check, medications to ease the strain on a damaged heart.

But regenerative medicine could dramatically change health care by shifting the emphasis to helping damaged tissue or organs repair themselves.”
