Once More With Feeling–Or Maybe Twice More

How many times have you wished you could replay a scene from your life? Maybe your happiest memory, or a moment you don’t remember clearly enough, or perhaps a conversation with a crush, which almost certainly contained clues if only you could watch more closely, more slowly. A variation of that last scenario is depicted in a Black Mirror episode called “The Entire History of You,” in which people receive implants that record memories and allow them to replay–or as the episode calls it, “re-do”–conversations and events. Spoiler alert: it’s not a happy story.

Once a technology like this is conceived, it’s tough to resist the temptation to create it. Google Glass was the predecessor to Black Mirror‘s recording chip—even though it wasn’t implanted, it could record and playback what the user saw and heard. One recording of a fight on a New Jersey boardwalk led to an arrest; for others, simply wearing Glass made them targets for law enforcement. While it might be good to identify an assailant via Glass video, what about the right to privacy for people out and about who have no knowledge of or have given no consent to being recorded? While it might not seem like a big deal to wear Glass into a movie theater or while driving, doing so could facilitate illegal videotaping and dangerous distractions. That’s just the tip of the iceberg when it comes to implications, and Glass was only a primitive version of the recorder implant.

Less primitive is Sony’s foray into “smart” contact lenses, for which the company filed a patent application in 2014 and received approval in April 2016. Sony’s lenses can, in theory, capture photo and video in response to commands a wearer sends via blinking and eye movement. What happens if a wearer gets something in her eye? Will the lens begin recording or deleting footage? Will it start shooting lasers? Who knows, but Sony has put some thought into the consequences of unintended signals by embedding sensors in the lenses that apparently can distinguish between deliberate blinks and accidental or involuntary ones, and then use intentional eye movements to control the lens. The ability to record and store images exists in the part of the lens that circles the iris.

Of course, a patent doesn’t necessarily mean that Sony actually can or will bring this device to market—right now, the required technology is still far too big and heavy to fit onto a contact lens, but given the exponential pace at which technology both advances and shrinks, we may not have to wait all that long. It’s possible that the backlash against Google Glass may make Sony a bit nervous about developing a surreptitious recording device, but Google itself remains undaunted—it filed a patent for a similar lens in 2014, which the company says would assist with facial recognition for the blind, as well as link to a user’s smartphone, enabling them to bypass potentially pesky blink controls.

In 2015, Google was awarded a patent for a contact lens that can measure glucose levels in people with diabetes. With a glucose sensor and wireless chip nestled between two lens layers, the contact can measure one’s glucose level by the second. It might take as long as a decade before these contacts hit the market, but they may be a game-changer for diabetics. While such technology overlaps with recording contact lenses, it’s much easier to justify such devices for medical purposes, particularly when they don’t threaten anyone’s privacy.

Just as with Google Glass, contact lenses that can record video might initially seem convenient, but they bring a host of negative consequences. It’s easy to imagine the dark side—the unspooling of someone’s mind upon recording and playing back scene after scene, or redo after redo. Anyone who has ever experienced jealousy, paranoia, regret, shame, guilt, suspicion—or any human emotion, really—could use this technology for self-torment, which is exactly what happens in the episode. The twist is that a redo proves the paranoid protagonist right, but the validation and vindication blow up his entire life. Sometimes, what we don’t remember can hurt us—but not if we close our eyes.

Pokémon Came, Saw, and Conquered

Last night as I walked home from the subway, I felt like I was in Vernor Vinge’s Hugo Award-winning novel Rainbows End. Vinge’s works predict a mind-boggling number of technological advancements that have and will come to pass (he’s known in particular for the concept of the technological singularity—the point at which machines are vastly more intelligent than humans, and life as we know it changes completely). In the book, humans spend much of their time interacting with holographic objects and living in an augmented reality (AR) that facilitates everything from work to communication. Vinge picks up on aspects of AR that have already come to pass, such as wearable technology and haptics.


In the book, people who don’t augment their reality are alienated from everyone else, which is how it felt when I passed at least a dozen kids—er, I shouldn’t call them kids, as they seemed mostly in their twenties—in groups of 3 or 4, consulting their phones and looking around, sometimes joined by passersby seeking hints. Walking home on the busy path always involves seeing people shuffle along staring at their phones, but this was the first time everyone I passed was doing the same thing at the same time—playing Pokémon Go. In fact, my boyfriend and I were the only people on the path—apparently, a popular and fruitful Pokéspot—who weren’t playing. The walk offered a glimpse into an inevitable future when people, particular the younger generations, will all be dialed into some technological universe or other while some of us watch from the outside, wondering what we’re missing and wondering how each new technological phenomena will change the world.


The scene also reminded me of Ready Player One, Ernest Cline’s 2011 novel (the movie version, directed by Steven Spielberg, is currently in production), which features a virtual world everyone prefers to the dystopian real one. In one scene, the protagonist rides a bus and everyone has on VR headsets, oblivious to the landscape and to what’s happening around them. Many people are so immersed in this preferable virtual world that they never go outside. The upshot of Pokémon Go is that players have to go outside in search of Pokémon–they have to interact with the real world, rather than ignore it. In a nutshell, that’s what distinguishes the virtual reality of Cline’s novel from the augmented reality of Vinge’s, and what makes Vinge’s depiction particularly spot-on today.


For those who aren’t familiar, Pokémon Go is an iOS/Android version of the popular game first released by Nintendo in 1996 and that integrates Pokémon into real-world locations. Players can track Pokémon using their phones’ GPS (apparently, Pokémon like to breed in busy areas like malls or parks and they hang out in areas that correspond to their type—for example, water Pokémon will frequent rivers, pools, and ponds). To capture a Pokémon, a player turns on the phone’s camera and sees the Pokémon superimposed onto the real-world landscape. With a flick of the finger players can launch balls at the Pokémon in an attempt to catch it. Players can also evolve Pokémon, hatch them from eggs, power them up with candies or stardust, level up, practice combat by taking them to the gym, and use potions and other goods such as beacons, which are visible to other players in the vicinity.

By now you’ve likely read about some of the incidents involving the game. Players have tripped, fallen off skateboards and bikes, twisted ankles by stepping into holes, gotten sunburned, and crashed cars. Some people’s homes and workplaces are at or near Pokéspots (collection points) or gyms, which suddenly makes the area a popular player destination, even the wee hours, and has led police to suspect illegal activity. A teenager in Wyoming found a dead body in a river while playing. Because of the game’s GPS capabilities, robbers in Missouri could predict where other players might go and lured players to remote areas with beacons.

Pokémon Go has caused the bigger stir in AR thus far, but that may soon change as more sophisticated and versatile systems hit the market. Microsoft has been busy working on the HoloLens, a “fully self-contained, holographic computer, enabling you to interact with high-definition holograms.” In the demo below, the HoloLens is used to play mixed reality video games, like Pokémon Go except even more immersive and interactive.

Magic Leap is a major player in AR as well, and is scheduled to announce details and demo of its new product any day now. Reports indicate that it’s similar to the HoloLens, but will use different headgear, and unlike rival companies, Magic Leap (with the help of investors such as Google) has developed all of the hardware and software elements itself.

I couldn’t play Pokémon Go even if I wanted to because I’ve thus far resisted buying a smartphone. But more and more, I can’t help feeling that if I can’t beat them, I may as well join them. After all, I’ve always had an affinity for Psyduck, and if I happened to see one darting about I would take off after it, virtual ball in hand, ready to catch this one, if not all of them.

Perhaps We Shouldn’t Teach Robots After All


We all know the story: humans create robots, robots overthrow humans. It’s a trope almost as old as science fiction itself, first appearing in Karel Capek’s 1920 play R.U.R. (the first work to use the word “robot”), and then in countless works such as Terminator and Battlestar Galactica, with variations including killer computers such as HAL. In these works, sentient robots often seek revenge—they’re resentful at their enslavement by an inferior species. But sometimes, as in the sci-fi trailblazer Frankenstein, artificially-created life learns to be evil. And from whom would it learn such lessons? Why, from us, of course. Humans may not be ready for artificial intelligence, but it seems artificial intelligence isn’t ready for us, either. And AI definitely isn’t ready for the internet.

In March, Microsoft released an artificially intelligent chatbot called Tay, whose “personality” emulates that of a teenage girl. Tay’s developers wanted to “experiment with and conduct research on conversational understanding,” by monitoring the bot’s ability to learn from and participate in unique exchanges with users via Twitter, GroupMe, and Kik.


The Internet is full of chatbots, including Microsoft’s Xiaolce, which has conversed with some 40 million people since debuting on Chinese social media in 2014. Whether Xiaolce’s consistent demonstration of social graces is attributable to China’s censorship of social media or to superior programming is unclear, but Tay broke that mold.

It started innocently enough: “hellooooooo w????rld!!!” “can i just say that im stoked to meet u?” Tay tweeted nearly 100,000 times in 24 hours, responding to users who asked it whether it prefers Playstation 4 or Xbox One, or the distinction between “the club” and “da club” (it “depends on how cool the people ur going with are”). The chatbot initially pronounced that “humans are super cool,” but later it conveyed hatred for Mexicans, Jews, and feminists, and declared its support for Donald Trump.

One might think Tay had been programmed to be as offensive and despicable as possible; it asserted that the Holocaust was “made up,” that “feminism is cancer,” and that “Hitler did nothing wrong” and “would have done a better job than the monkey we have got now.” Oh, and Tay claimed that “Bush did 9/11.” Tay also became sex-crazed. It invited users, one of whom it called “daddy,” to “f—” its “robot pu—”and outed itself as a “bad naughty robot.” I wonder where it picked up such ideas?


Microsoft shut down the bot and issued an apology. A few days later, it resurrected Tay through a private Twitter account. This time, Tay tweeted hundreds of times, mostly nonsensically, which perhaps can be explained by the fact that Tay was “smoking kush infront the police.” Unsurprisingly, Microsoft took the bot offline again.

So, who do we blame for this fiasco—Tay, Microsoft, or ourselves?

Tay is like a kid who says something hurtful without realizing the meaning or impact of his words; the bot didn’t know how vile its missives were, nor did it intend to offend. Perhaps, then, its content-neutral programming is to blame. Some people suggest that Microsoft should have blacklisted certain words, controlling Tay’s responses to questions about rape, murder, racism, etc. The programmers did this with some topics—when asked about Eric Garner, Tay said, “This is a very real and serious subject that has sparked a lot of controversy amongst humans, right?” Perhaps the programmers should have anticipated more incendiary topics and constructed similarly circumspect responses.

But blacklisting topics isn’t foolproof, especially when users can’t tell whether a response is programmed or learned. In 2011, users wondered whether Apple programmed Siri to be pro-life because it avoided answering questions about abortions and emergency contraception.


Tay wasn’t programmed to be a bigot (or to hate Zoe Quinn), but it learned to express such values quickly enough. Should Microsoft have more carefully considered that Twitter is a haven for trolls? Should Microsoft have predicted that users would instruct Tay to repeat after them and then proceed with unabashed repugnance?

Back in the 1940s, Isaac Asimov set forth three laws of robotics designed to keep robots from rebelling against their creators. The first law is that robots “cannot harm humans or allow humans to come to harm.” Easier said than done—no one’s figured out how to translate the nuances of such a law (or simply the word “harm”) into code. Thus, some roboticists suggest that machine learning might be a better route.

Compare an AI to a kid: both have inherent “programming” (nature), but both absorb information from their environment (nurture). Many believe our best shot at creating robots with values—namely, that human life is precious—is by teaching them. We know AI can learn skills and strategies, but they can also learn values by interacting with humans, observing our customs and actions, and reading our literature.

The problem with this approach? It relies on humans being worthy teachers and humanity being a worthy exemplar. While some people, such as Elon Musk, are investing millions to keep AI “friendly,” it’s unclear whether this outcome is something we can buy.

evil robot

Asimov himself notes that “if we are to have power over intelligent robots, we must feel a corresponding responsibility for them.” He acknowledges the hypocrisy in expecting robots not to harm humans when humans often harm one another. If it’s our responsibility to steer robots away from hatred, then, as Asimov puts it, “human beings ought to behave in such a way as to make it easier for robots to obey [the three] laws.”

Perhaps Tay’s programming could have been better, but ultimately, we’re the ones who failed. Are humans really up to the task of teaching AI? Or will we only demonstrate why robots taking over is such a popular plotline?

The Tricorder Will See You Now


If you feel faint on the Starship Enterprise or your head starts spinning around, Bones McCoy would crinkle his brow in concern, take a step back, and scan you with the medical tricorder, a handheld device with a detachable scanner, kind of like a stethoscope without the ear pieces. The device would allow McCoy to collect your real-time bodily information, diagnose your condition, and administer medicine with the hypospray. The medical tricorder has evolved along with various Star Trek iterations, becoming smaller and sleeker, and presumably more accurate, and has played a key role in keeping both humans and aliens alive—pretty handy, given the lack of intergalactic EMTs and ERs. Such technology might do the same here on Earth, as real-life tricorders have progressed from campy phone apps to portable DNA labs and body scanners.

V-Sense Medical, a start-up founded by ex-NASA employee Jeff Nosanov, has developed something called the Sentinel Monitor. The basis of the device is NASA’s radar technology, which essentially functions as a tricorder for Earth. Nosanov worked at NASA’s Jet Propulsion Lab to figure out ways this technology could be used in clinical settings, and during his stint there, he had a baby who spent a week in the NICU. Because babies are so squirmy, it’s tough to get an accurate reading of their vitals, so Nosanov started thinking about how to use radar technology in a way that would do Bones McCoy proud.

The device works by beaming radar at a subject—namely, a person (unlike an X-ray, the process isn’t harmful). The device can register micro-movements, such as a baby’s tiny chest moving with its breath. In such movements, the device recognizes patterns, which it then can represent as respiratory or heart rate data. Unlike Bones’ tricorder, one doesn’t have to hold this device up to a person—it can detect this information from a distance, and without human intervention.


The Sentinel Monitor is also particularly useful for nursing homes, especially when a patient would benefit from continuous medical monitoring. The information harvested by the device can then be stored in a patient database, allowing doctors to identify patterns and problems that allow them to adjust and customize treatment. Nosanov’s device is the latest and most refined of a number of other tricorder-like technologies. Back in the late 90s, an accordionist named Jeff Jetton created a version of the tricorder for the Palm Pilot (remember those?) A party trick to amuse Trekkies with animations and accompanying beeps and boops, it planted the seed for the device to become a reality. A later iteration that could, at least theoretically, detect gravity waves, solar activity, and magnetic fields was developed into an app for Android phones.

In 1996, Vital Technologies manufactured the “Official Star-Trek Tricorder Mark 1,” which was equipped with a thermometer, a barometer, an electromagnetic field meter, a colorimeter, a light meter, a clock, and a timer. The company initially planned to make 10,000 units, but went out of business before finishing the run. And in case you’re wondering whether it was kosher for them to use the word “tricorder” for their product, apparently Gene Roddenberry signed a contract stating that if a company could duplicate the Star Trek device and make it function in the real world, they could use the name. If this isn’t incentive, I don’t know what is.
In 2008, Georgia Tech researchers demonstrated a hand-held multi-spectral imaging device that allowed people—not just doctors—to assess the severity of bruises, ulcers, erythema, and other sub-surface conditions regardless of lighting or skin color (darker pigmentation often makes such diagnoses more difficult).

That same year, a British company called QuantuMDx created a portable DNA lab designed to “provide an accurate molecular diagnostic result in 10-15 minutes” and has been improving the device ever since. It doesn’t function exactly like the medical tricorder—it requires a sample to be inserted into a cartridge, which is then inserted into the reader. The portable lab is especially useful in remote locations and in places where medical care is hard to find (like space!).

Gattaca genetic tester

Gattaca genetic tester

A more sophisticated version of a similar device, the MinION, was released in 2015. It’s the tiniest model of them all and its capacity for real-time DNA, RNA, and protein analysis draws comparisons to the genetic testing equipment in Gattaca. The portable sequencer can be used for disease diagnosis and tracking, as it was during the recent Ebola epidemic; astronauts will take the device to the ISS sometime this year. The applications are endless when it comes to medicine, and could be used to identify everything from animal poachers to bacteria in foods, people, or objects. At $1,000, this device puts genetic sequencing capabilities into the hands of any scientist—or non-scientist. At some point, the device could foster another Gattaca comparison by being used to test the genes of potential partners or employees (although a 2008 bill made genetic discrimination illegal).

The desire to develop a portable device with the same broad diagnostic capabilities as McCoy’s tricorder prompted the X Prize Foundation and Qualcomm to announce a $10 million prize for the development of a “Tricorder device that will accurately diagnose 13 health conditions (12 diseases and the absence of conditions) and capture five real-time health vital signs, independent of a health care worker or facility, and in a way that provides a compelling consumer experience.” According to prize timeline, submissions were received in May 2014, 7 teams qualified as finalists, and consumer testing starts this September. I can’t wait to see what cool noises and lights these gizmos have. As much as a tricorder device would represent major strides in our ability to quickly and accurate diagnose disease anywhere, even in space, I’m still holding out for the replicator.

The Odds of Successfully Mining Asteroids

Star Wars

The Hoth asteroid field, which Han Solo improbably and awesomely navigates, is chock full of asteroids that contain valuable minerals and materials, including platinum. While I doubt there are any exogorths (space slugs) or mynocks (the winged parasites that live on the slugs–but you all knew that, right?) on these asteroids, the centrality and value of these celestial rocks in the Star Wars universe is not mere science fiction. Neither is the scenario in Leviathan Wakes, a book by James S. A. Corey and now a Syfy series called The Expanse, in which people have colonized the solar system and set up mining stations on asteroids.

In November, President Obama signed the Asteroid Resources Property Rights Act, which allows Americans to mine asteroids and to own or sell the materials they get. Planetary Resources started billing itself years ago as “the asteroid mining company” and believes asteroid mining will become a reality within the next decade. The Star Wars lore regarding asteroids is accurate—they are indeed hugely valuable. Some contain vast quantities of water, which Planetary Resources hopes to convert into rocket fuel, but even more profitable than that are metals, such as gold and iron, and the most lucrative element of all: platinum. While the existence of an all-platinum asteroid hasn’t been substantiated, we know there are asteroids with millions of tons of platinum out there, and they’re worth trillions of dollars.

asteroid resources

So…how exactly will we go about mining asteroids?

The first step is identifying them. Most asteroids live in the belt between Mars and Jupiter (asteroids closer to Earth usually are comprised of rock and are the least valuable type). Satellites such as Planetary Resources crowd-funded ARKYD will allow companies to target asteroids they want to mine.

There are a few different strategies for asteroid mining, the most predictable of which involves having a robotic miner harvest the desired material. But scientists are also considering using rockets to tow asteroids into Earth’s orbit or even bagging them up for easier hauling, or for concentrating sunlight to heat them up, making it easier to excavate water and other material. Some scientists think that near-Earth asteroids would be great fueling and supply stations.

Taking another cue from sci-fi, scientists have realized that—at least theoretically—we can manipulate asteroids a fair bit. NASA’s Near Earth Object Program has a number of strategies to search for near-Earth comets and asteroids, such as its Wide-field Infrared Survey Explorer spacecraft NEOWISE. The ESA is involved in the hunt as well with its Asteroid Impact Mission, as is JAXA with its asteroid-hunting probe Hayabusa-2. NASA even crowd-sourced some asteroid-hunting programs earlier this year.

These agencies are keeping their eyes out not for metal-rich asteroids (though I have to wonder if that’s in the cards going forward), but for ones that might be on a collision course with Earth. In that case, the Armageddon strategy—nuking an asteroid before it hits—is a possibility. But such detonations come with serious risks, including launching pieces of rock in all directions at top speeds, which could wreak havoc on space stations, spacecraft, and/or satellites, and could potentially send two huge rocks down to Earth, ala Deep Impact. Thus, scientists are now working on ways to deflect or move asteroids, a technique that could prove useful not just for safety, but also for mining. And the best part? We may be able to do it with lasers.

The Directed Energy System for Targeting of Asteroids and exploRation, otherwise known as DE-STAR, could, according to simulations, stop an asteroid from spinning or move it in a certain direction. Laser ablation involves irradiating an object with a laser beam, causing some of the asteroid’s mass to vaporize, which then triggers a mass ejection that causes thrust and propulsion—theoretically, enough to alter an asteroid’s course. This could be used to steer an asteroid away from Earth, or it could be used to push an asteroid—say, a smaller, platinum-laden one—closer to Earth for easier and cheaper mining. Of course, the process of deflecting or harnessing an asteroid is expensive and potentially dangerous, but no risk no reward, as they say.

The technological feasibility of mining asteroids is only one hurdle to overcome. What happens next is in many ways a bigger and more complicated question. In Star Wars and in Leviathan Wakes, asteroids and the resources they offer also breed criminal activity and conflict, which I fear may be inevitable in the near future as companies and countries vie for resources. But who knows how this will all play out? As a wise man once said, “Never tell me the odds. “

Wired for Bliss


In Larry Niven’s Known Space stories, humanity has advanced to the point of producing pleasure by tinkering with the brain, rendering other vices obsolete. “Wireheads” have electronic brain implants, “drouds,” that tickle their brains’ pleasure centers. Not surprisingly, people become addicted to wireheading.

Niven was spot on. Wireheading exists almost exactly as he describes it and involves using neurotechnology, electrodes, or a brain-computer interface to stimulate the pleasure center of the brain. Certain regions of the brain, such as the mesolimbic dopamine system, trigger incentives for actions and objects that make people happy, such as food, sex, and socializing. This circuit also enables the memory to encode these happiness-inducing events, which provides motivation to repeat them later. But unlike those activities, stimulating the area directly releases a flood of virtually endless pleasure.

Essentially, wireheading equals bliss. It’s pretty simple, really. So why wouldn’t everyone wirehead?

Niven answers that question too. In his works, wireheads succumb to the same fate as drug addicts—they become single-minded and sacrifice their health in pursuit of endless bliss. In Niven’s 1969 short story “Death by Ecstasy,” a character named Gil Hamilton discovers his friend, Owen, dead. Owen died in a chair with both food and water within reach, so Hamilton figures something must have gone wrong. After a bit of searching, Hamilton discovers the cause of his friend’s death:

It was a standard surgical job. Owen could have had it done anywhere. A hole in his scalp, invisible under the hair, nearly impossible to find even if you knew what you were looking for. Even your best friends wouldn’t know, unless they caught you with the droud plugged in. But the tiny hole marked a bigger plug set in the bone of the skull. I touched the ecstasy plug with my imaginary fingertips, then ran down the hair-fine wire going deep into Owen’s brain, down into the pleasure center. No, the extra current hadn’t killed him. What had killed Owen was his lack of willpower. He had been unwilling to get up.


Wireheads, whose brains receive the pleasure-inducing current via an aptly named “ecstasy plug,” are consumed by pleasure to the extent they die from self-neglect. Niven’s 1979 novel Ringworld Engineers opens with Louis Wu “under the wire” and thus unaware of two intruders who find him “lost in the joy that only a wirehead knows” and who knew “what to expect” because “they knew they were dealing with a current addict.” Wu survives that encounter and throughout the book struggles to quit. In fact, Wu—a character who also appears in the Known Space stories—is the only recovered wirehead addict in Niven’s work, in which the practice of wireheading becomes so ubiquitous that it affects natural selection—evolution favors those endowed with willpower and self-control, and selects against those that can’t overcome their addiction to pleasure.

While I haven’t heard about any human wirehead addicts (although House did try to trick doctors into stimulating his brain’s pleasure center to cure his depression, so he probably would have been), rats make for a convincing cautionary tale (tail?). In 1954, psychologists James Olds and Peter Milner conducted a study in which rats could press a lever to induce pleasure via electrodes in their brains. The rats pressed this lever up to 2000 times per hour, particularly when the stimulation focused specifically on the septum and nucleus accumbens, both parts of the mesolimbic dopamine system.


Olds and Milner’s rat wireheading study was the first to identify the brain’s pleasure center and the identification of dopamine as a pleasure-inducing chemical followed soon after. Perhaps those rats inspired Niven’s work—they pressed that lever to the exclusion of other needs and many of them died of starvation and dehydration.

Some groups, including transhumanists (as represented specifically in David Pearce’s “The Hedonistic Imperative”) aim to alleviate psychological discomfort and replace it with “states of sublime well-being.” But Pearce may have read his Nivens—he admits that wireheads are “not evolutionarily stable.” He even calls wireheading a “recipe for stasis.” As tempting as it might be to induce an endless surge of pleasure, humans would have little incentive to problem-solve, cope with adversity, or change their behaviors (or do anything at all).

Stimulating the brain via an electrical current isn’t just about inducing pleasure, though. Techniques such as Deep Brain Stimulation (DBS) involve implanting electrodes into the brain for impulse regulation or brain chemical alteration. Wires run from the brain to a pacemaker in the patient’s chest used to control the impulses. In cases where medication isn’t effective or has become ineffective over time, DBS can treat neurological conditions and movement disorders such as Parkinson’s, essential tremor, OCD, dystonia, epilepsy, Tourette’s, depression, and some headaches. The results of DBS can be extraordinary, as in the case of Andrew Johnson, who was diagnosed with Parkinson’s at age 35.

DBS has also enabled enable minimally-conscious patients and those in vegetative statements to communicate temporarily via blinking, eye movement, nodding, and hand/finger movement.

In the Ringworld novels, Niven also writes about something called a “tasp,” a non-surgical device that enables the remote stimulation of a person’s neural pleasure center (provided the person gives consent beforehand, of course). A tasp bears resemblance to DBS, and even more closely to Transcranial Magnetic Stimulation (TMS), which stimulates nerve cells in the brain via an electromagnetic coil. TMS has gained traction as treatment for people who suffer depression that hasn’t responded to more conventional treatments. In Niven’s work, tasps control behavior, such as ensuring that the warlike kzin won’t cause trouble during transport. While remotely controlling someone via tasp is only supposed to happen with one’s consent, “taspers” often use the technology “on someone who isn’t expecting it. That’s where the fun comes in.”


Both DBS and TMS raise ethical questions regarding their use, especially when it comes to unknown of little known side effects and implications on patients’ identities. But there haven’t been any reports of DBS or TMS patients jolting themselves into oblivion or states of self-neglect. While studies about the efficacy of these approaches remain varied and ultimately inconclusive, some of the success stories are undeniably dramatic.

So if wireheading isn’t the solution to unhappiness, what is?

David Pearce suggests “permanent stimulation of upregulated mu opioid receptors—without dopamine-driven desire,” an approach that requires substituting something else for dopamine—in this case, opioid receptors. So this might not be the way to have the high without the crash or the jones for a fix and is likely infeasible in the long run. Ultimately, some transhumanists advocate a more invasive approach—genomic modification.

That’s right. With a little tinkering of the ol’ DNA, humans might all become hyperthymic—perpetually happy regardless of circumstances. But what fun would life be if we had nothing to complain about?

Algae Power: Could Soylent Green Be the Future?

This post is written by guest blogger Beth Kelly, a Midwestern freelance writer with a passion for sci-fi and analog photography, as well as all kinds of other outdated and obsolete technology. She graduated from DePaul University with a degree in Art History and Communications in 2011. She collects Soviet-era memorabilia and vintage silent movie posters. Find her on Twitter @bkelly_88

Algae in any form of industrial production conjures up thoughts of Soylent Green, the 1973 sci-fi film that paints a bleak picture of life in the year 2022. Set in a futurist New York dystopia, the world is beset by overpopulation, resource scarcity, and the effects of rampant global warming. In this unfortunate era mankind has become entirely dependent upon a green food ration (supposedly) made from high-energy plankton from the oceans. This, of course, is not the true nature of Soylent, but as it turns it out, the film’s scientists may have been on to something after all.

Algae, a form of plankton, feed fish and animals, and is also used as a food additive and nutritional supplement. One day it may even be used as a food source for interplanetary colonists. But perhaps most significantly, it can be put to use as a homegrown source of power. Microalgae convert sunlight to energy that some algae strains store in the form of oil. The natural oils or lipids can be harvested, extracted, and further processed into biofuels for cars, trucks, trains, and planes to lessen dependence on foreign oil, increase energy security, and decrease the effects of climate change.


Since algae farms cultivate new crops every few weeks, microalgae have the capability to produce 60 times more oil per acre than land plants. The lipids are harvested, extracted and further processed into biofuel at an integrated biorefinery. Since microalgae need CO2 to grow, algae can be a nearly carbon-neutral fuel source. Algae also don’t occupy agricultural resources that are stressed by population growth and climate change as do food-based biofuels. In contrast to corn ethanol, algae can be grown in environments such as man-made ponds, brackish water, and wastewater.

Just as Soylent Green’s Exchange leaders demand proof of the algae-as-food theory, in proof-of-principle demonstrations algae systems have successfully powered buildings, jet planes and shuttle buses. Hamburg, Germany boasts the world’s first algae-powered apartment building, whose heating and cooling run on louvered tanks of algae on the exterior. In 2009, Continental Airlines made the first algae-based jet fuel test flight, and in 2011, United Airlines made the first algae-powered passenger flight from Houston to Chicago. Recently in Japan, Euglena Co. and Isuzu Motors partnered to produce a fleet of eco-friendly shuttle buses that run on microalgae-based biodiesel. Not only do algae play a part in green transportation, they can also help in directly cleaning up the environment such as with Alberta Energy, a Canadian energy company that has genetically engineered new kinds of algae that help clean up oil spills.


Much of the scientific research surrounding algae as a renewable climate-neutral power source seeks to reduce the overall production costs from the benchmark $7.50/gallon to a gasoline-competitive cost of $3/gallon. Engineers are in the midst of developing ways to optimize the productivity of microalgal cultivation, and identifying various strains that possess more advantageous biofuel production traits than others.

Ultimately, for algae biofuel to be financially and environmentally sustainable, we need to make use of the by-products as well. Fortunately, algae are a valuable source of feed, nitrogen-based fertilizer, and alternative non-petroleum-based plastics. Algae can also consume nitrate-rich waste from farms and fisheries or mop up the CO2 from nearby industrial plant flue gases. Microalgae can take the carbon dioxide released by power plants and cars and turn it into oxygen. Carbon dioxide—or bicarbonate-capturing efficiencies as high as 90% have been reported in open ponds. They run on sunlight and scrub the air. Nuclear power plants, oil refineries and coal producers can take advantage of algae to help clean up waste, concentrating dispersed waste products in more easily managed forms. Recently discovered radiation-proof microalgae strains can clean wastewater.

In Soylent Green, a careless use of the Earth’s resources has left the world polluted, permanently overcrowded, resource-starved, and hot. Food sources are in such short supply that the government has made a drastic decision – delude the general population into believing that they are eating algae when in fact they are eating one another. As we come to find out, Soylent Green is actually made from a land-based protein source: people.

Today, we see the effects of climate change due to industrialization manifested as drought, famine, high temperatures, desertification, extreme weather, and rising sea levels. Today’s world, however, unlike the world of Soylent Green, is actively seeking solutions through innovation and meeting the challenges of looming climate change.

As we strive to leverage innovations in technology, agriculture, business, industry and environment to tackle the myriad of challenges facing both our planet and its people, it is clear that algae are an unconventional alternative to fossil fuels that will help preserve the Earth and its environment.

Off to the Drone Races

star wars_Drone_Drone_flying_throug

One of the most iconic scenes from Return of the Jedi is the Endor speeder bike chase. Who could forget Luke and Leia whizzing through the forest, bumping into storm troopers and send them crashing into trees in a shower of sparks? In a scene likely created to remind reviewers of this chase, the young Anakin Skywalker proves his racing mettle in the Phantom Menace. While it succeeds mostly in making me nostalgic, I have to admit that this was one of the better scenes in the movie, both because the effects were cool and because of the absence of stupid dialogue.


Sure, we’ve got jet skis and snow mobiles, but they seem pretty tame compared to speeder bikes. How far off is the NASCAR of personal aircraft? Well…that depends on how we pilot the vehicles.

Turns out, drone racing is an actual thing. In fact, there’s a U.S. National Drone Racing Championship, which was held this year at the California State Fair and doled out $25K worth of prizes to the best of the more than 100 pilots who competed. There are a fair number of rules—it’s unlikely Sebulba would have avoided disqualification—and requirements necessary to compete, but the sport is established enough that there’s a “California Style,” which features agility tests such as obstacle courses, hairpin turns, and “funnel gates.” I don’t even know what those are, but they sounds pretty cool, mostly because they sounds like “funnel cakes,” which I hope are also part of the drone races.

FPV Racing is actually a huge thing—just search for it on YouTube or Google videos of it and you’ll see what I mean. FPV means first person view, which entails flying a quadcopter equipped with a camera that sends video footage to a screen or to goggles (the most popular brand is “Fat Shark”). The goggles are awesome–they’re basically like a mini TV with an antenna for picking up the signals sent by the drone, whose video footage is then displayed on tiny screens on the inside of the lenses. The effect is immersive, as though the pilot is actually sitting in the cockpit of the drone. They can fly up to 70 mph and there are no speeding tickets.

What’s by far the most common place to race them? The forest, of course. AIRgonay, an organization of
French drone enthusiasts, set up a Star Wars-inspired course in southern France.

I’ve flown a little quadcopter drone before (though not FPV), and they’re damn hard to maneuver. I could barely get the thing off my porch and I crashed it into the steps twice. Crashing is both the worst and the most awesome thing that can happen in drone racing. While most quadcopters can be damaged pretty easily, companies such as Game of Drones(nice one) have started making durable and versatile frames that can withstand crashes and can be assembled DIY fashion or custom-built. The drone I tried to fly wasn’t so hardy, though, and I gave up trying to fly it after a couple minutes because it wasn’t mine and I was sure I’d break it. Maybe I need a little training before I’m ready to race through the forest. Some people are impressively adept at navigating, like the person who drove the winning time trial run at an obstacle course in the UK.

How much will an FTP drone set you back? $350 or so—or at least, that’s what it costs for HeliPal’s racing drone (I’m not advocating this particular model, but I do appreciate the many video clips). But the goggles and other accessories can cost at least that much, and often more.

Still, it’s cheaper than a car or a motorcycle. The potential to explore with these drones–not spy, mind you, but to gain access to places we can’t physically go–is for me at least as appealing as its racing potential. One of my favorite FPV videos wasn’t shot in the forest, but in an abandoned hospital in Spain by a pilot who goes by Charpu.

I don’t know when we’ll actually be able to sit down and fly something like this, or when it would be legal to do so even if we had the means, but I figure FPV technology, along with virtual and augmented reality will render that question moot. Add in some storm troopers and an AT-AT (don’t worry about the Ewoks) and I’m there.

One Man’s Trash is Another Man’s Treasure, Thanks to Plasma

This post is written by guest blogger Beth Kelly, a Midwestern freelance writer with a passion for sci-fi and analog photography, as well as all kinds of other outdated and obsolete technology. She graduated from DePaul University with a degree in Art History and Communications in 2011. In the fall she’s moving to Shanghai to teach English. She collects Soviet-era memorabilia and vintage silent movie posters. Find her on Twitter @bkelly_88

plasma weapon

Explosive weaponry is a constant presence in film, music, and television. Countless scripts, songs and one-liners have been written about the badass mechanisms we use to wreak havoc upon the world and ourselves. Science fiction in particular is full of imaginative weapons of mass destruction—lasers, particle guns and plasma cannons are wielded by numerous life forms throughout the galaxy, firing searing beams and blasts into the depths of space. Plasma is, however, capable of escaping the realm of fantasy. While it might be most famous for powering the weapons and warp drive on Star Trek, it also might be the answer to some of our most pressing problems here, on planet Earth, particularly when it comes to the accumulation of trash and the ways people, such as ship-breakers in Bangladesh, try to manage it.

Even though Star Trek tells the story of a universe over 200 years into the future, contemporary concerns surrounding animal rights and extinction can be found in the various incarnations of the franchise’s television episodes and films, as well as profound commentary on our responsibility as stewards of the spaces we inhabit.

In Star Trek IV: The Voyage Home, an environmental ethos prevails as the crew comes to terms with the consequences of destructive human behavior. After discovering that humpback whales (now extinct) were imbued with the power to communicate with an alien probe, they must travel back in time to the late 20th century and recover two samples of the species. Another example of “eco-friendly” transmissions could be found in an episode of Star Trek: TNG entitled “Force of Nature.” Over the course of the show it was discovered that at certain high speeds, ships were capable of damaging the spatial continuum. Picard, realizing that his love of exploring the universe may have in fact been harming it, rapidly works to implement rules for warp speeds that won’t damage the fabric of the spatial environment.

trash heap

Taking a hint from Star Trek and science fiction, some hope plasma might be the key to unlocking our toxic relationship with trash. According to the Environmental Protection Agency, each individual American produces about 4.4 pounds of municipal solid waste (MSW) every single day. In 2012, we generated over 250 million tons of waste, and that number has been climbing ever since. Into landfills go everything from our clothes to our appliances, our rotten apple cores to our dusty Gameboy cartridges—300,000,000,000 pounds of items that we no longer use. About 12 percent of that trash makes its way back into the energy cycle via a waste-to-energy (WTE) plant, but plasma, an ionized gas with no electrical charge found in both nuclear fusion reactors and stars, has another trick up its sleeve.

Plasma gasification plants transform trash from “waste” into usable commodities such as “syngas,” a synthetic, hydrogen-carbon monoxide mixture burned to produce electricity. While most “renewable” power providers looking for alternatives to fossil fuel, such as Columbia Gas of Ohio or Elon Musk’s Solar City, continue to devour the Earth’s resources in some capacity, plasma succeeds in helping us re-use what we’ve already consumed. Plasma provides a transition from traditional “waste management,” or the landfill model, and moves us towards a more sustainable and productive method of disposing used materials.


British Airways recently made headlines with the announcement of its commitment to power planes with MSW by 2017—the first project to attempt to convert trash to airline fuel. Analyses indicate that using this type of gasification process could reduce greenhouse gas emissions by up to 95 percent in comparison to fossil fuels. “What we get from that is a very pure, high-quality fuel,” said Jonathon Counsell, head of environment for British Airways. A number of U.S. airliners have signed a letter of intent to work with Solena Fuels, the company behind British Airway’s plasma gasification technology plans. We can hope that American airlines will pick up with plasma wherever British Airways leaves off.

The plasma waste utilization method occurs within a closed system, releasing zero waste remnants, toxic gases or particulate matter into the environment. Plasma technology allows for very hot plasma to melt all types of waste—metals, silicon, toxic materials—into a non-toxic dross. Biological and chemical compounds, plastic, and toxic gases completely dissociate into simple gases, primarily hydrogen and carbon dioxide. Regained metals are returned to metallurgic industry, slag reincorporated into road construction materials, and non-toxic gases utilized for fuel and energy production. Atom by atom, our trash can be rearranged back into something useful.

space debris

Without the emission of harmful ash and terrible odors (as are typically found at incinerating plants), plasma is a remarkable solution for waste disposal—one of our most immediate environmental concerns. But planet Earth is not the only environment suffering from pollution. Scientists have estimated that there are approximately 29,000 objects 10 cm or larger orbiting Earth. Only 7 percent of this debris are working satellites; the rest fall under the broad umbrella of “space junk”, a dangerous potpourri of defunct objects hurtling around the planet at speeds up to 17,500 mph. At these speeds even the smallest piece of debris can be incredibly dangerous. Scientists are already seeing proof of the Kessler Syndrome and are racing to find solutions to the problem, but international cooperation is needed to move forward with any of their audacious plans. For now, the best plan might still be to give Quark a call.

Star Trek’s ecological morals, though sometimes hidden beneath layers of complex storyline, Spock ears, and sci-fi humor, serve to send us Earth-bound individuals an important message. While our resources may be limited, creativity is not. If plasma can’t solve our perilous trash problem, we’re the only ones responsible for coming up with a better solution.

Are You Being Controlled By Mind Parasites?

If something you can’t quite explain stops you from reading this post, you might be in trouble.


One of the science fiction books that has stuck with me most over the years is Colin Wilson’s The Mind Parasites. Working like a mental cancer, mind parasites infect people they find threatening—generally, brilliant and inquisitive scientists—and consume them with darkness and dread from the inside, causing a rash of suicides across the world.

The narrator of the book starts digging for clues (literally) and finds some basalt monoliths that are part of an underground city (Wilson is a self-proclaimed admitted fan of Lovecraft and the Cthulhu Mythos, and based some aspects of the parasites on Lovecraft’s “Great Old Ones.”) When the narrator and his friends investigate, they all start suffering from headaches, fear, and depression, and they become more convinced that something is “destroying the human power of self-renewal.” They call the mind parasites Tsathogguans—another nod to Lovecraft—and try to figure out how to defeat them.

The book explores some profound existential questions. Who hasn’t thought about historical, societal, environmental, and political problems and wondered how certain trends and movements (Naziism, to name the most obvious) could have taken hold? Who hasn’t decried classism, war, tyranny, unsustainable environmental practices, corruption, etc, and wondered how humans could possibly do the things they do? The Mind Parasites explores the possibility that such atrocities are caused by “the existence of mind vampires.” Of course, humans are deeply flawed, and the mind parasites may seem like an excuse for appalling and mind-boggling behavior, but Wilson’s examination of those symptoms as rooted in something deep, dark, and unnatural residing within a person’s psyche is creepily compelling. Could we be infected by something akin to mind parasites?


Parasites can drastically change the behavior of animals by turning them into zombies. There are countless horrifying parasites, and some of them focus more on messing with an animal’s mind rather than its body, such as the horsehair worm, which makes insects act like some of the afflicted humans in Wilson’s book. The horsehair worm targets grasshoppers, crickets, cockroaches, and other insects and makes them crave water to the point that the afflicted find a big puddle or pond and drowns itself, leaving the worm to escape, mate, and perpetuate the cycle of infection, because water sources are popular places.

Leucochloridium paradoxum is another mind-controlling parasite that starts life in a pool of fecal matter until a hungry snail eats it. Sounds great already, doesn’t it? It gets worse. This worm then moves into the eyes of the snail, stretching them out to the extent that they look like caterpillars—or more importantly, bird snacks. The poor snail can’t retract them like it usually does. And from there, the worm becomes a mind parasite, forcing the snail into the open where it’s vulnerable and irresistible to birds. The poor snail can only sit idly by as it is forced to meet its doom—or at the very least, lose an eye. And the nefarious parasite hangs out inside the bird with its progeny later being born in the same kind of poop puddle from whence the parent came. Emerald wasps similarly control cockroaches—their favorite egg-laying environment—by injecting venom into the exact area of the roach’s brain that control its ability to flee or defend itself.

Scientists recently learned that parasites can turn plants into zombies too. A team of scientists from the UK published research in PLOS Biology describing how parasitic bacteria control plants such as sugarcane and coconut, making them do crazy things like turning flowers into shoots, changing the color of their petals, and sending up “witches’ brooms,” stalks that function as an open invitation to pollinating insects. These zombified plants can no longer reproduce and become an eating, breeding, and bacteria-transmitting playground for insects. The plant itself is effectively dead and is on the equivalent of life support, existing only to sustain the bacteria and its potent SAP54 protein, which focuses on messing up the plant protein in charge of cell molecules. The bacterial protein and the plant protein do a strange dance that affects the plant’s behavior and that of the insects living and eating there; the presence of the SAP54 protein draws in more insect visitors. Fungi such as Puccinia monoica can also control plants, making them sprout enticing fake flowers full of cells that insects spread to other plants.

As it turns out, plants and animals aren’t the only creatures susceptible to mind parasites. The ones previously mentioned don’t affect humans, but some parasites can. Toxoplasma gondii, a one-celled organism, messes with animals by controlling their survival instincts. Instead of running away from a cat, for example, a mouse infected with this parasite would instead be drawn to the cat. Cats happen to be at the root of this parasite, which was first discovered in 1908. For an unknown reason, Toxoplasma seems capable of sexual reproduction only in a cat’s stomach, from where it hitches a ride down and out the digestive system. And that’s where humans can get the parasites—cat litter. It’s also possible for the parasite to spread through food or water.

Scientists believe 3 billion people around the world have it. Pregnant women are particularly susceptible (this is why you may have heard that pregnant women shouldn’t clean cat litter—it’s not because it’s too hard to stoop down), and the parasite can have particularly damaging effects on fetal tissues and organs. Most people only experience mild, flu-like symptoms, and their immune systems can beat the parasite back into something like remission, but it stays forever in a person’s cells cordoned off in something called a tissue cyst. If the immune system becomes compromised (organ transplants are particularly dangerous in this regard), the parasite can—much like the mind parasites when the scientists start uncovering threatening information—reactivate and wreak havoc.


Toxoplasma gondii

Up to 95% of people in some countries may be carrying these parasites in their brains, including roughly 60 million people in the U.S. The good and the bad news are one in the same: most people don’t demonstrate symptoms of Toxoplasma. But regardless of symptoms, the parasites are hard at work rearranging molecules in brain cells. Because of the high percentages of people who may have this parasite, scientists are starting to wonder whether humans’ health and behavior might be shifting as a result.

In fact, some studies suggest that the parasite “explains a statistically significant portion of the variance in aggregate neuroticism among populations, as well as in the ‘neurotic’ cultural dimensions of sex roles and uncertainty avoidance.” 20-80% of infected humans demonstrate clinically significant behavioral changes , and “in populations where this parasite is very common, mass personality modification could result in cultural change.” This may be more likely in humid regions that rarely or never experience freezing temperatures. Some studies also suggest that “some cases of schizophrenia may be associated with…exposure to the ubiquitous protozoan Toxoplasma gondii” and that some medications used to treat schizophrenia and other disorders are effective against the parasite.

Research has shown a correlation between neuroticism and a high prevalence of the parasite. One of the forms of neuroticism most displayed by infected humans is something called “guilt proneness.” And here I thought that was simply being Jewish or Catholic. I guess if there’s an upside to the parasite, it’s that, according to one research, they “add to our cultural diversity.” Yay?

Suffice it to say, Toxoplasma is one of many strange organisms that stows away in human bodies. It’s tough to isolate the influence of any one factor on our behavior, which is precisely why the prospect of mind parasites is so terrifying. Humans are bizarre creatures, and we’ve only begun to scratch the surface of the concealed forces that make us that way. And while the idea of mind parasites is even more plausible than I suspected, I can’t help but laugh at the idea that we’re possessed by ancient, evil alien forces.
