New flexible batteries and OLED (Organic Light Emitting Diode) may lead to foldable computing. From Dani Fankhauser at Mashable: “Innovation in lighting is great, but the real game-changer is when OLED is used on a flexible surface for a bendable device. ‘The first benefit will be thinner and lightweight, less breakable displays,’ say Janice Mahon, VP of Technology Commercialization at Universal Display Corporation.

She describes what industry insiders call a ‘universal communication device,’ which is essentially a pen, but with a display that rolls in and out. It seems our aspirations are towards forever smaller devices.”

I don’t know if a robotic insect will be perfected by 2015, but it probably won’t be long. From George Dvorsky at i09:

Every once in a while, there’s news which reminds us that we’re living in the age of accelerating change. This is one of those times: A new project has been announced in which scientists at the Universities of Sheffield and Sussex are hoping to create the first accurate computer simulation of a honey bee brain — and then upload it into an autonomous flying robot.

This is obviously a huge win for science — but it could also save the world. The researchers hope a robotic insect could supplement or replace the shrinking population of honey bees that pollinate essential plant life.”

I’ve of course read Ron Rosenbaum’s seminal 1971 Phone Phreak story in Esquire, but I hadn’t come across the coverage of that subculture from Ramparts until now. In 1972, that publication ran step-by-step instructions of how someone could receive phone calls for free, sans blue box. In 1993, it published a piece by Bruce Sterling about the history of hacking which explained the pre-Phreak politicized past of phone rip-offs, which was a signature of the Yippie movement. An excerpt:

“Abbie Hoffman is said to have caused the Federal Bureau of Investigation to amass the single largest investigation file ever opened on an individual American citizen. (If this is true, it is still questionable whether the FBI regarded Abbie Hoffman a serious public threat -quite possibly, his file was enormous simply because Hoffman left colorful legendry wherever he went). He was a gifted publicist, who regarded electronic media as both playground and weapon. He actively enjoyed manipulating network TV and other gullible, imagehungry media, with various weird lies, mindboggling rumors, impersonation scams, and other sinister distortions, all absolutely guaranteed to upset cops, Presidential candidates, and federal judges. Hoffman’s most famous work was a book self-reflexively known as Steal This Book, which publicized a number of methods by which young, penniless hippie agitators might live off the fat of a system supported by humorless drones. Steal This Book, whose title urged readers to damage the very means of distribution which had put it into their hands, might be described as a spiritual ancestor of a computer virus.

Hoffman, like many a later conspirator, made extensive use of pay- phones for his agitation work — in his case, generally through the use of cheap brass washers as coin-slugs.

During the Vietnam War, there was a federal surtax imposed on telephone service; Hoffman and his cohorts could, and did, argue that in systematically stealing phone service they were engaging in civil disobedience: virtuously denying tax funds to an illegal and immoral war. But this thin veil of decency was soon dropped entirely. Ripping-off the System found its own justification in deep alienation and a basic outlaw contempt for conventional bourgeois values. Ingenious, vaguely politicized varieties of rip-off, which might be described as ‘anarchy by convenience,’ became very popular in Yippie circles, and because rip-off was so useful, it was to survive the Yippie movement itself. In the early 1970s, it required fairly limited expertise and ingenuity to cheat payphones, to divert ‘free’ electricity and gas service, or to rob vending machines and parking meters for handy pocket change. It also required a conspiracy to spread this knowledge, and the gall and nerve actually to commit petty theft, but the Yippies had these qualifications in plenty. In June 1971, Abbie Hoffman and a telephone enthusiast sarcastically known as ‘Al Bell’ began publishing a newsletter called Youth International Party Line. This newsletter was dedicated to collating and spreading Yippie rip-off techniques, especially of phones, to the joy of the freewheeling underground and the insensate rage of all straight people.

As a political tactic, phone-service theft ensured that Yippie advocates would always have ready access to the long-distance telephone as a medium, despite the Yippies’ chronic lack of organization, discipline, money, or even a steady home address.

Party Line was run out of Greenwich Village for a couple of years, then ‘Al Bell’ more or less defected from the faltering ranks of Yippiedom, changing the newsletter’s name to TAP or Technical Assistance Program. After the Vietnam War ended, the steam began leaking rapidly out of American radical dissent. But by this time, ‘Bell’ and his dozen or so core contributors had the bit between their teeth, and had begun to derive tremendous gut-level satisfaction from the sensation of pure technical power.

TAP articles, once highly politicized, became pitilessly jargonized and technical, in homage or parody to the Bell System’s own technical documents, which TAP studied closely, gutted, and reproduced without permission. The TAP elite revelled in gloating possession of the specialized knowledge necessary to beat the system.

‘Al Bell’ dropped out of the game by the late 70s, and ‘Tom Edison’ took over; TAP readers (some 1400 of them, all told) now began to show more interest in telex switches and the growing phenomenon of computer systems. In 1983, ‘Tom Edison’ had his computer stolen and his house set on fire by an arsonist. This was an eventually mortal blow to TAP (though the legendary name was to be resurrected in 1990 by a young Kentuckian computeroutlaw named ‘Predat0r.’)

Ever since telephones began to make money, there have been people willing to rob and defraud phone companies. The legions of petty phone thieves vastly outnumber those ‘phone phreaks’ who ‘explore the system’ for the sake of the intellectual challenge. The New York metropolitan area (long in the vanguard of American crime) claims over 150,000 physical attacks on pay telephones every year! Studied carefully, a modern payphone reveals itself as a little fortress, carefully designed and redesigned over generations, to resist coinslugs, zaps of electricity, chunks of coin-shaped ice, prybars, magnets, lockpicks, blasting caps. Public pay- phones must survive in a world of unfriendly, greedy people, and a modern payphone is as exquisitely evolved as a cactus.”

That brilliant Stewart Brand knew forty years ago that the coming connectivity of computers would eventually bring dark days to newspapers and record stores. And the virtual businesses that are replacing them aren’t adequate to support the old model. The excellent indie band Grizzly Bear is living the new normal. From Nitsuh Abebe in New York:

“For much of the late-twentieth century, you might have assumed that musicians with a top-twenty sales week and a Radio City show—say, the U2 tour in 1984, after The Unforgettable Fire—made at least as much as their dentists. Those days are long and irretrievably gone, but some of the mental habits linger. ‘People probably have an inflated idea of what we make,’ says [Edward] Droste. ‘Bands appear so much bigger than they really are now, because no one’s buying records. But they’ll go to giant shows.’ Grizzly Bear tours for the bulk of its income, like most bands; licensing a song might provide each member with ‘a nice little ‘Yay, I don’t have to pay rent for two months.’’ They don’t all have health insurance. Droste’s covered via his husband, Chad, an interior designer; they live in the same 450-square-foot Williamsburg apartment he occupied before Yellow House. When the band tours, it can afford a bus, an extra keyboard player, and sound and lighting engineers. (That U2 tour had a wardrobe manager.) After covering expenses like recording, publicity, and all the other machinery of a successful act (‘Agents, lawyers, tour managers, the merch girl, the venues take a merch cut; Ticketmaster takes their cut; the manager gets a percentage; publishers get a percentage’), Grizzly Bear’s members bring home … well, they’d rather not get into it. ‘I just think it’s inappropriate,’ says Droste. ‘Obviously we’re surviving. Some of us have health insurance, some of us don’t, we basically all live in the same places, no one’s renting private jets. Come to your own conclusions.'”

Are fears of cyber attacks that paralyze electric grids overstated? In a new Foreign Policy piece, Douglas Birch argues in the affirmative. An excerpt about the dual mass power outages from last summer in America and India:

“The most important thing about both events is what didn’t happen. Planes didn’t fall out of the sky. Governments didn’t collapse. Thousands of people weren’t killed. Despite disruption and delay, harried public officials, emergency workers, and beleaguered publics mostly muddled through.

The summer’s blackouts strongly suggest that a cyber weapon that took down an electric grid even for several days could turn out to be little more than a weapon of mass inconvenience.

‘Reasonable people would have expected a lot of bad things to happen’ in the storm’s aftermath, said Neal A. Pollard, a terrorism expert who teaches at Georgetown University and has served on the United Nation’s Expert Working Group on the use of the Internet for terrorist purposes. However, he said, emergency services, hospitals, and air traffic control towers have backup systems to handle short-term disruptions in power supplies. After the derecho, Pollard noted, a generator truck even showed up in the parking lot of his supermarket.

The response wasn’t perfect, judging by the heat-related deaths and lengthy delays in the United States in restoring power. But nor were the people without power as helpless or clueless as is sometimes assumed.”

I became a vegetarian because I don’t want to hurt animals, the environment or myself. I won’t have any measurable impact on the first two, so I guess it’s all about me. Isn’t it always? Rumpus has a really good Q&A by Suzanne Koven with Dr. Neal Bernard, the son of cattle ranchers who now advocates for veganism for ethical and health reasons. An excerpt about the belief that carnivorism is a product of evolution:

“Rumpus: 

But isn’t there an evolutionary basis for meat eating—for us not to be disgusted by it? We have canine teeth, our forebears speared animals and ate them. Aren’t we hardwired for meat eating? Is the fact that cooking meat smells good to us really just a cultural thing?

Barnard: 

Meat smells good, bleu cheese smells good—to some people. But it’s acquired. If you ask a guy who’s thirty-five if a cold beer on a hot summer day would taste good, he’d say, ‘Yeah, that would taste wonderful.’ But if you could go back in time to his first taste behind the garage when he was fifteen, it probably tasted disgusting. We acquire certain tastes for things.

And if you took a baby and put a bunny in front of him, and if you had a cat and a bunny, the cat at any age would want to attack and kill the bunny and the child would say, ‘Oh, look at the bunny!’ So the idea that we have some innate aggression towards animals…we don’t.

h: if you open the mouth of a cat, a carnivore, you see that they have long canines, way beyond the other teeth. If you open the mouth of a dog, you see the same. If you open your mouth, you don’t. You have canines that are the same length as your incisors. If you have long canine teeth, it allows you to do two things: one, it allows you to snatch your prey. The other thing it allows you to do is to pull away the hide. If a dog happens to catch a rabbit or another animal, it can very easily remove the hide. If a cat catches a squirrel, they have no trouble with that. But if a person does that, they will work all day and all night to get the skin off of an animal, because they don’t have long canine teeth anymore.

We also don’t have claws. Plus we’re not fast. Plus we don’t have very good vision, or good sense of smell. An owl is a predator and can detect a mouse at a tremendous distance. Dogs have a sense of smell much greater than ours and they’re much faster than we are. We have fairly dull senses, fairly slow locomotion. In our Olympic trials, we celebrate speeds that would be an embarrassment to a bird or a dog or another animal.

We have nothing to kill prey with and nothing to remove the hide with. So the question is when did that change come? It’s something like 3.5 million years ago that we lost our long canine teeth. And most of the great apes did, too—and they’re almost entirely vegetarian. Chimpanzees will eat a little bit of meat. But, they never eat dairy products, and no other animal would do that.” (Thanks Browser.)

My best guess is that anyone being born now (and perhaps many of the rest of us) will live to see cures for macular degeneration and glaucoma and most causes of blindness. But at the very least, we will develop workarounds so that the blind can regain a reasonable measure of sight. From Kyle Vanhemert at Fast Company:

“Advanced age-related macular degeneration is the leading cause of blindness in the U.S. in adults over the age of 60. It affects nearly 2 million people in the U.S., with half a million new cases diagnosed every year. It’s a big problem. And until recently, we didn’t have a very good way of treating it. Patients with end-stage degeneration typically had to rely on cumbersome, low-tech solutions to help them see–relics like handheld magnifying glasses and closed-circuit televisions. But earlier this month, a team of surgeons at the UC Davis Eye Center introduced a promising new solution: a tiny, implantable telescope.”

I recently put up a post about transient electronics. Here’s a DARPA video demonstrating  such technology dissolving when treated with a few drops of water.

From a recent Atlantic article by Ross Andersen about video artist Jason Silva, a passage recalling a meeting between Marshall McLuhan and Timothy Leary, when the latter was imprisoned:

When Timothy Leary was in prison he was visited by Marshall McLuhan, who told Leary “you can’t stay way out on the fringes if you want to compete in the marketplace of ideas—if your ideas are going to resonate, you need to refine your packaging.” And so they taught Leary to smile, and they taught him about charisma and aesthetic packaging, and ultimately Leary came to appreciate the power of media packaging for his work. According to the article, this is where Timothy Leary the performance philosopher was born, and when he came out of jail all of the sudden he was on all these talk shows, and he was waxing philosophical about virtual reality, and downloading our minds, and moving into cyberspace. All of these ideas became associated with this extremely charismatic guy who was considered equal parts rock star, poet and guru scientist—and that to me suggests the true power of media communications, because these guys were able to take these intergalactic sized ideas and spread them with the tools of media.•

From an Ask Me Anything at Slashdot with Steve Wozniak, an exchange about improving American education:

Question:

Woz, what changes would you recommend to fix the K-12 education system in the U.S.?

Steve Wozniak:

Computers offered a real change in the tools of the classroom, but they don’t seem to have changed much. The learning is the same, only done via computers, for the most part. I had hoped for more.

I do want to feel a part of the big improvement someday, so I hope that there is some further step with computers. That would be when a computer becomes conscious and caring and becomes the best friend that each student wants to be with. It will look at their faces and speak the way that particular student likes and be a good friend more than a teacher.

One thing that has not changed over time in education is that we all, in a class, get the same material presentation together. The same pages as everyone else on Monday, the same pages on Tuesday, etc. Individuals as we are, we have different lapses along the way. A teacher could back up and explain something to fill in a gap, but each of the 30 students has different ‘gaps.’ The solution will be the equivalent of one teacher per student.

This opens the door to a student choosing to get only straight A’s, and only studying subjects they want to. And there will be more room to teach thinking and creativity and not all the same answer, which is not even their own answer, but out of a book. It’s a brave step, but right.

I learned the capital cities of all 50 states. How could anyone in life ever need to know such a worthless thing. The only worth is to show you can memorize it. But today it gets turned into a grade and a determination of what intelligence is. We have to break from that paradigm but can’t with today’s 30-student classes. Or should I say ‘day care?’

Schools are short of money because students don’t get a vote and votes turn into money. It’s a bad consequence of finding education to be a right and that means it has to be supplied by government. Government money follows votes. A family of 5 gets no more votes than a family of 2. Which wants the better school? But the votes by families of 2 are against more money for schools.”

From “How to Make Almost Anything,” Neil Gershenfeld’s new Foreign Affairs piece about the coming revolution of 3D printers, replicating machines that can replicate even themselves:

“Are there dangers to this sort of technology? In 1986, the engineer Eric Drexler, whose doctoral thesis at MIT was the first in molecular nanotechnology, wrote about what he called ‘gray goo,’ a doomsday scenario in which a self-reproducing system multiplies out of control, spreads over the earth, and consumes all its resources. In 2000, Bill Joy, a computing pioneer, wrote in Wired magazine about the threat of extremists building self-reproducing weapons of mass destruction. He concluded that there are some areas of research that humans should not pursue. In 2003, a worried Prince Charles asked the Royal Society, the United Kingdom’s fellowship of eminent scientists, to assess the risks of nanotechnology and self-replicating systems.

Although alarming, Drexler’s scenario does not apply to the self-reproducing assemblers that are now under development: these require an external source of power and the input of nonnatural materials. Although biological warfare is a serious concern, it is not a new one; there has been an arms race in biology going on since the dawn of evolution.

A more immediate threat is that digital fabrication could be used to produce weapons of individual destruction. An amateur gunsmith has already used a 3-D printer to make the lower receiver of a semiautomatic rifle, the AR-15. This heavily regulated part holds the bullets and carries the gun’s serial number. A German hacker made 3-D copies of tightly controlled police handcuff keys. Two of my own students, Will Langford and Matt Keeter, made master keys, without access to the originals, for luggage padlocks approved by the U.S. Transportation Security Administration. They x-rayed the locks with a CT scanner in our lab, used the data to build a 3-D computer model of the locks, worked out what the master key was, and then produced working keys with three different processes: numerically controlled milling, 3-D printing, and molding and casting.

These kinds of anecdotes have led to calls to regulate 3-D printers.” (Thanks Browser.)

From a 1975 “Talk of the Town” piece in the New Yorker by Anthony Hiss about a trip to Los Angeles, a passage detailing his audience with Philip K. Dick, who wasn’t fully appreciated during his abbreviated lifetime (or in this brief article):

In the afternoon, we drove over to Fullerton to see Philip K. Dick, my favorite science-fiction writer, author of 33 novels and 170 short stories. Past the House of Egg Roll, past Moy’s Coffee Shop (Chop Suey, Hot Cakes), past Bowser Beautiful, through Bel Air. We drove to the end of Sunset Boulevard, where we saw seagulls, 18 surfers in wet suits, a blue suggestion of Catalina to the southwest, and an Indian girl in a green-and-gold sari on the beach. Then south, past a concrete wall painted ‘TOMMY SURKO SAYS FOR MY KIND OF GIRL THERE’S ONLY ONE! TOMMY SURKO!’ Behind the tall palms on Venice we could see snow on the mountains. Kids were skateboarding down a hill on Lincoln. Past Woody’s Smorgasburger, onto a freeway to Fullerton.

Philip K. Dick lives in an apartment full of books and records and photographs with his wife, Tessa; his small son, Christopher; and two cats, Harvey Wallbanger and Sasha. He is jolly and tubby and bearded. His books, which are hilarious, are popular in France, because the French think they are about how grim everything is. Dick showed us a French newspaper piece about him—the subtitles were “Le Chaos,” “L’Acide,” “Le Suicide,” “Les Machines” “La Société Totalitaire,” “La Paranoïa.” Dick has just finished a book about Tim Leary and the LSD crowd, and what happened to them.

We had stopped in to make a short call of homage, and wound up talking along for hours, drinking wine, and Tessa going out for some Chinese food, and then talking about cosmologies until it was almost time for our plane back to N.Y. The apartment also contains a two-foot-high metal rocket ship on a wooden base—this is his Hugo Award, the highest award in science fiction. The plaque is missing, though, because Dick once used the award to break up a fight. ‘It grabs good,’ he says. As for the cosmologies, this is what emerged from our discussions: cosmologies all seem to be based on repetition—you know, first the universe expands, then it contracts, then it expands again, etc.—but maybe that’s not so. Maybe this whole expansion business that the universe is currently embarked upon is going to happen only once. That would mean that every day really is a new day, right? Also, maybe it’s not true that Einstein was smarter than Newton. Maybe Newton’s laws accurately described the universe as it then existed. But since then it’s expanded and got more complicated, and can be accurately described only by Einstein physics. Which will eventually become outdated, maybe.”•

The argument over health care reform should never have been about if the U.S. should have universal coverage but how best to limit waste and provide excellent service. That might have happened if conservative opportunists hadn’t sought political advantage in roiling Birther bigotry as a way to take down a President who was using policies suggested by the Heritage Foundation (e.g., individual mandate). These conservative do not want smaller government; they just want power. From “The Conservative Case for Obamacare,” by J.D. Kleinke in the New York Times:

“The core drivers of the health care act are market principles formulated by conservative economists, designed to correct structural flaws in our health insurance system — principles originally embraced by Republicans as a market alternative to the Clinton plan in the early 1990s. The president’s program extends the current health care system — mostly employer-based coverage, administered by commercial health insurers, with care delivered by fee-for-service doctors and hospitals — by removing the biggest obstacles to that system’s functioning like a competitive marketplace.

Chief among these obstacles are market limitations imposed by the problematic nature of health insurance, which requires that younger, healthier people subsidize older, sicker ones. Because such participation is often expensive and always voluntary, millions have simply opted out, a risky bet emboldened by the 24/7 presence of the heavily subsidized emergency room down the street. The health care law forcibly repatriates these gamblers, along with those who cannot afford to participate in a market that ultimately cross-subsidizes their medical misfortunes anyway, when they get sick and show up in that E.R. And it outlaws discrimination against those who want to participate but cannot because of their medical histories. Put aside the considerable legislative detritus of the act, and its aim is clear: to rationalize a dysfunctional health insurance marketplace.

This explains why the health insurance industry has been quietly supporting the plan all along. It levels the playing field and expands the potential market by tens of millions of new customers.”

Umbraphiles, or sun worshippers, are apparently growing in numbers, perhaps because we are starstuff ourselves. Solar eclipses, infrequent though they are, have recently spawned a healthy tourist industry. From Martin Ince in the Financial Times:

“Tour operators report a surge in interest in eclipse viewing, sparked by the ‘eclipse of the century’ in July 2009. It was visible across large parts of India and China and lasted six minutes 39 seconds – the longest eclipse until 2132. It filled every hotel in the Yangtze Delta region, where over 30,000 eclipse watchers based themselves, and brought an extra 7,000 foreign tourists to Shanghai, mostly from the US and Japan. China Daily reported at the time that about 80 special flights were staged to allow passengers to see the eclipse even if clouds threatened: a good move, as it rained in Shanghai.

‘We’re finding this sort of holiday to be hugely popular since the China eclipse, and the trend continued for Easter Island the following year,’ says Simon Grove, head of product at the tour operator Explore. ‘I think the appeal of astronomical tourism in general has increased in recent years too. Last year’s spectacular Northern Lights helped to fuel interest that those well-publicised eclipses had ignited.’

Part of the joy of this hobby is that the moon’s shadow can fall anywhere on the earth’s surface. This means eclipse-chasing needs careful planning, but also that eclipse-lovers end up in places they would never visit otherwise, including Easter Island and the Antarctic in the past few years. This year’s eclipse will take me to Palm Cove, Queensland; the six others I have witnessed were in locations as diverse as the Greek islands, Siberia, and a tiny power station village in rural China.”

The opening of a really smart Aeon essay by economist John Quiggin, who wonders whether we will embrace a world free of toil:

“I first became an economist in the early 1970s, at a time when revolutionary change still seemed like an imminent possibility and when utopian ideas were everywhere, exemplified by the Situationist slogan of 1968: ‘Be realistic. Demand the impossible.’ Preferring to think in terms of the possible I was much influenced by an essay called ‘Economic Possibilities for our Grandchildren,’ written in 1930 by John Maynard Keynes, the great economist whose ideas still dominated economic policy making at the time.

Like the rest of Keynes’s work, the essay ceased to be discussed very much during the decades of free-market liberalism that led up to the global financial crisis of 2007 and the ensuing depression, through which most of the developed world is still struggling. And, also like the rest of Keynes’s work, this essay has enjoyed a revival of interest in recent years, promoted most notably by the Keynes biographer Robert Skidelsky and his son Edward.

The Skidelskys have revived Keynes’s case for leisure, in the sense of time free to use as we please, as opposed to idleness. As they point out, their argument draws on a tradition that goes back to the ancients. But Keynes offered something quite new: the idea that leisure could be an option for all, not merely for an aristocratic minority.” (Thanks Browser.)

As technology is increasingly used to do war’s dirty work, will military continue to be made up mostly of young males? From Rosa Brooks’ Foreign Policy argument for rethinking recruitment in the Information Age:

“For most of human history, having an army full of young men made lots of sense. As soldiers, young males have had two things going for them, historically speaking. First, they’re usually stronger, on average, than any other demographic group: they can run fast and carry heavy loads. Second, they’re (relatively) biologically expendable from a species-survival perspective: women of child-bearing age are the limiting factor in population growth. A society can lose a lot of young men without a devastating impact on overall population growth.

Today, though, these characteristics don’t matter as much as they once did. Overall birthrates are much lower in modern societies than they were during earlier periods, but life expectancy is much longer. Early societies worried about sustaining their populations; today we worry less about ensuring population growth than about overburdening the planet’s load-bearing capacity.

Simple brawn also offers far less advantage in our high-tech age. In modern warfare, brutal hand-to-hand combat is no longer the norm, and warfare is no longer a matter of sending out wave after wave of troops to overwhelm the enemy through sheer mass. Increasingly, modern warfare involves a mixture of high-tech skills and low-tech cultural knowledge rather than ‘fighting’ in the traditional sense.

In fact, if the next few decades are anything like the last, most military personnel will never see combat.”

The introduction to Megan Garber’s excellent history of mechanical horses in the Atlantic:

“For most of human history, horses have been, primarily, a technology. An intimate technology, yes — people named their horses, and groomed them, and sometimes loved them — but horses were, for the most part, tools: They helped humanity to get around and get things done. Once steam power and internal combustion came along, though, that relationship changed drastically. As horses were eclipsed by more efficient methods of moving people and things — trains, cars, planes — their role in human culture shifted, as well. We quickly came to see horses more as what they had been, of course, all along: fellow animals. 

That shift is evident in a longstanding dream that is a little bit fanciful, a little bit practical, a little bit silly, and a little bit wonderful: the quest for the mechanical horse. While some creations — theScammel mechanical horse, the Iron Horse — imagined themselves as horses’ mechanized successors while not actually resembling them, many others have engaged in biomimicry of a more specific variety. While they are only one species we humans have seen fit to imitate with our machines — the world now hosts, among other automatons, the mechanical dog, the mechanical dinosaur, the mechanical pack mule, the mechanical elephant, the mechanical flea, and the mechanical shark — horses have held a special place in human hearts.”

The opening of Amy Barth’s new Discover article about Optogenics, which is showing promise as a way to bring about profound behavioral modification through the use of flashes of light:

“Stopped at a red light on his drive home from work, Karl Deisseroth contemplates one of his patients, a woman with depression so entrenched that she had been unresponsive to drugs and electroshock therapy for years. The red turns to green and Deisseroth accelerates, navigating roads and intersections with one part of his mind while another part considers a very different set of pathways that also can be regulated by a system of lights. In his lab at Stanford University’s Clark Center, Deisseroth is developing a remarkable way to switch brain cells off and on by exposing them to targeted green, yellow, or blue flashes. With that ability, he is learning how to regulate the flow of information in the brain.

Deisseroth’s technique, known broadly as optogenetics, could bring new hope to his most desperate patients. In a series of provocative experiments, he has already cured the symptoms of psychiatric disease in mice. Optogenetics also shows promise for defeating drug addiction. When Deisseroth exposed a set of test mice to cocaine and then flipped a switch, pulsing bright yellow light into their brains, the expected rush of euphoria—the prelude to addiction—was instantly blocked. Almost miraculously, they were immune to the cocaine high; the mice left the drug den as uninterested as if they had never been exposed.

Today, those breakthroughs have been demonstrated in only a small number of test animals. But as Deisseroth pulls into his driveway he is optimistic about what tomorrow’s work could bring: Human applications, and the relief they could deliver, may not be far off.” (Thanks Browser.)

Brad Templeton considers a potential use for the coming robotic autos: “whistlecars,” which can deliver themselves to you for a small fee whenever you need to drive someplace. It’s the taxi without the taxi driver, and the vehicle can return itself. An excerpt:

“Many of the big changes that will come about form robocars will come from how they free car designers from the constraints of human-driven cars which are the owner’s sole, or almost-sole vehicle.

Much of this depends on this yet-untested idea:

  • If one can hire a cheap specialized ‘robotaxi’ (or whistlecar) on demand when one has a special automotive need, car users can elect to purchase a vehicle only for their most common needs, rather than trying to meet almost all of them — or to not purchase at all.

For example, for many, most trips are short, single passenger and do not require significant cargo room. Almost nobody purchases a vehicle good only for that purpose, because they want to cover the occasional needs for long trips, taking extra people, carrying cargo, towing or going off-road.

Some of these changes would also apply to what I’m calling ‘whistlecars’ — owned or rented cars that deliver themselves to you when you summon them, but which you still drive.” (Thanks Atlantic.)

The opening of a BBC piece by James Gallagher about “transient electronics,” which dissolve within the human body after serving a medical purpose:

“Ultra-thin electronics that dissolve inside the body have been devised by scientists in the US and could be used for a range of medical roles.

The devices can ‘melt away’ once their job is done, according to research published in the journal Science.

The technology has already been used to heat a wound to keep it free from infection by bacteria.

The components are made of silicon and magnesium oxide, and placed in a protective layer of silk.

It is part of a field termed ‘transient electronics’ and comes from researchers who have already developed ‘electronic tattoos’ – sensors that bend and stretch with the skin.”

By any standards, Luther Burbank was a virtuoso botanist and horticulturist, mixing, matching and creating. Among the hundreds of exotic varieties that were hatched from his experimental Santa Rosa farm, greenhouse and nursery–which included plants, potatoes, fruits and flowers–was the spineless cactus featured in the above classic photograph. The opening of an admiring 1906 New York Times profile of Burbank:

Every summer our transatlantic steamers are burdened with great throngs of travelers beginning their pilgrimages to the shrines of departed genius. In America, too, we may visit places made illustrious by the former presence of Washington, Jefferson, Lee, Lincoln, Emerson, Poe, and other native men of genius. But, disguise it as we will, the visits are at last to cemeteries, where everything is described in the past tense.

But there is in America at this moment a man of the very greatest genius, just in the flower of his fame, a visit to whom not only emphasizes his genius and his leadership in thought and living things, but also enables one to see far into the future. There is a searchlight of truth in constant operation at Santa Rosa, Cal., and the mind and heart of Luther Burbank are the lenses through which the light is focused. Long ago I resolved to beg the privilege of standing near the searchlight and making a few observations as it illumined some of the peaks of knowledge I could never hope to scale.

Our so-called “Captains of Industry” are busy men, but many of their duties and responsibilities they may delegate to others. Luther Burbank is the busiest man in the world. I make that statement without fear of successful contradiction. His ship is alone on a vast sea of nature’s secrets. With him on the voyage of discovery are a few near relations to encourage him, a dear friend or two for protection and companionship, and several humble helpers to feed the boilers and oil the engines. But he is more alone than was Columbus, because he has no first officer, no second officer, no mate. Like Columbus, upon him alone falls the responsibility for the expedition; he alone knows why the vessel’s prow is kept always in one direction; he alone has faith that it must ultimately touch the shores of truth and reality.•

According to Dr. Rich Terrile of NASA, one day–and perhaps soon–our computers and robots are going to “awaken” and take over the planet. Okay, whatever. I’m fine with it. We had our shot and effed it up. An excerpt from an interview in Vice which Ben Makuch conducted with the jet propulsion expert:

“Vice:

Listening to you talk about Moore’s Law and our exponential growth in computing makes me wonder what you think about the future, and the fate of humanity?

Dr. Rich Terrile:

OK, well this is where it gets really uncomfortable. I have great hopes for our future, but I don’t necessarily have great hopes for humanity. I think we’ll become something different.

Vice:

What do you mean, like androids?

Dr. Rich Terrile:

I think our machines will wake up and take over our society. They will become us, we will become them. Right now everybody has their own consciousness and we can’t really exchange information very efficiently like computers can. They can exchange tremendous amounts of information and live forever sharing that information at the speed of light, whereas human beings are really quite constrained. We’re caught up in the constraints of our biological evolutionary baggage. I think we’re going to shed that once our machines become conscious. We’ll find ways of continuing our society, but in a different way.

Vice:

So you’re saying in the next hundred years humans will cease to be humans and become machines?

Dr. Rich Terrile:

Yes, I think we’ll merge with machines.

Vice:

Is this something a lot of scientists agree on?

Dr. Rich Terrile:

I don’t think a lot of scientists think about this sort of thing. I think the ones who do inevitably come to the conclusion that there’s a lot of credibility to these kinds of arguments.”
