the face of the Internet

The Disappearing Woman and Life on the Internet

This article originally appeared on TomDispatch.

The Web is regularly hailed for its “openness” and that’s where the confusion begins, since “open” in no way means “equal.” While the Internet may create space for many voices, it also reflects and often amplifies real-world inequities in striking ways.

An elaborate system organized around hubs and links, the Web has a surprising degree of inequality built into its very architecture. Its traffic, for instance, tends to be distributed according to “power laws,” which follow what’s known as the 80/20 rule -- 80% of a desirable resource goes to 20% of the population.

In fact, as anyone knows who has followed the histories of Google, Apple, Amazon, and Facebook, now among the biggest companies in the world, the Web is increasingly a winner-take-all, rich-get-richer sort of place, which means the disparate percentages in those power laws are only likely to look uglier over time.

Powerful and exceedingly familiar hierarchies have come to define the digital realm, whether you’re considering its economics or the social world it reflects and represents.  Not surprisingly, then, well-off white men are wildly overrepresented both in the tech industry and online.

Just take a look at gender and the Web comes quickly into focus, leaving you with a vivid sense of which direction the Internet is heading in and -- small hint -- it’s not toward equality or democracy.

Experts, Trolls, and What Your Mom Doesn’t Know

As a start, in the perfectly real world women shoulder a disproportionate share of household and child-rearing responsibilities, leaving them substantially less leisure time to spend online. Though a handful of high-powered celebrity “mommy bloggers” have managed to attract massive audiences and ad revenue by documenting their daily travails, they are the exceptions not the rule. In professional fields like philosophy, law, and science, where blogging has become popular, women are notoriously underrepresented; by one count, for instance, only around 20% of science bloggers are women.

An otherwise optimistic white paper by the British think tank Demos touching on the rise of amateur creativity online reported that white males are far more likely to be “hobbyists with professional standards” than other social groups, while you won’t be shocked to learn that low-income women with dependent children lag far behind. Even among the highly connected college-age set, research reveals a stark divergence in rates of online participation.

Socioeconomic status, race, and gender all play significant roles in a who’s who of the online world, with men considerably more likely to participate than women. “These findings suggest that Internet access may not, in and of itself, level the playing field when it comes to potential pay-offs of being online,” warns Eszter Hargittai, a sociologist at Northwestern University. Put simply, closing the so-called digital divide still leaves a noticeable gap; the more privileged your background, the more likely that you’ll reap the additional benefits of new technologies.

Some of the obstacles to online engagement are psychological, unconscious, and invidious. In a revealing study conducted twice over a span of five years -- and yielding the same results both times -- Hargittai tested and interviewed 100 Internet users and found that there was no significant variation in their online competency. In terms of sheer ability, the sexes were equal. The difference was in their self-assessments.

It came down to this: The men were certain they did well, while the women were wracked by self-doubt. “Not a single woman among all our female study subjects called herself an ‘expert’ user,” Hargittai noted, “while not a single male ranked himself as a complete novice or ‘not at all skilled.’” As you might imagine, how you think of yourself as an online contributor deeply influences how much you’re likely to contribute online.

The results of Hargittai’s study hardly surprised me. I’ve seen endless female friends be passed over by less talented, more assertive men. I’ve had countless people -- older and male, always -- assume that someone else must have conducted the interviews for my documentary films, as though a young woman couldn’t have managed such a thing without assistance. Research shows that people routinely underestimate women’s abilities, not least women themselves.

When it comes to specialized technical know-how, women are assumed to be less competent unless they prove otherwise. In tech circles, for example, new gadgets and programs are often introduced as being “so easy your mother or grandmother could use them.” A typical piece in the New York Times was titled “How to Explain Bitcoin to Your Mom.” (Assumedly, dad already gets it.) This kind of sexism leapt directly from the offline world onto the Web and may only have intensified there.

And it gets worse. Racist, sexist, and homophobic harassment or “trolling” has become a depressingly routine aspect of online life.

Many prominent women have spoken up about their experiences being bullied and intimidated online -- scenarios that sometimes escalate into the release of private information, including home addresses, e-mail passwords, and social security numbers, or simply devolve into an Internet version of stalking. Esteemed classicist Mary Beard, for example, “received online death threats and menaces of sexual assault” after a television appearance last year, as did British activist Caroline Criado-Perez after she successfully campaigned to get more images of women onto British banknotes.

Young women musicians and writers often find themselves targeted online by men who want to silence them. “The people who were posting comments about me were speculating as to how many abortions I’ve had, and they talked about ‘hate-fucking’ me,” blogger Jill Filipovic told the Guardian after photos of her were uploaded to a vitriolic online forum. Laurie Penny, a young political columnist who has faced similar persecution and recently published an ebook called Cybersexism, touched a nerve by calling a woman’s opinion the “short skirt” of the Internet: “Having one and flaunting it is somehow asking an amorphous mass of almost-entirely male keyboard-bashers to tell you how they’d like to rape, kill, and urinate on you.”

Alas, the trouble doesn’t end there. Women who are increasingly speaking out against harassers are frequently accused of wanting to stifle free speech. Or they are told to “lighten up” and that the harassment, however stressful and upsetting, isn’t real because it’s only happening online, that it’s just “harmless locker-room talk.”

As things currently stand, each woman is left alone to devise a coping mechanism as if her situation were unique. Yet these are never isolated incidents, however venomously personal the insults may be. (One harasser called Beard -- and by online standards of hate speech this was mild -- "a vile, spiteful excuse for a woman, who eats too much cabbage and has cheese straws for teeth.”)

Indeed, a University of Maryland study strongly suggests just how programmatic such abuse is. Those posting with female usernames, researchers were shocked to discover, received 25 times as many malicious messages as those whose designations were masculine or ambiguous. The findings were so alarming that the authors advised parents to instruct their daughters to use sex-neutral monikers online. “Kids can still exercise plenty of creativity and self-expression without divulging their gender,” a well-meaning professor said, effectively accepting that young girls must hide who they are to participate in digital life.

Over the last few months, a number of black women with substantial social media presences conducted an informal experiment of their own. Fed up with the fire hose of animosity aimed at them, Jamie Nesbitt Golden and others adopted masculine Twitter avatars. Golden replaced her photo with that of a hip, bearded, young white man, though she kept her bio and continued to communicate in her own voice. “The number of snarky, condescending tweets dropped off considerably, and discussions on race and gender were less volatile,” Golden wrote, marveling at how simply changing a photo transformed reactions to her. “Once I went back to Black, it was back to business as usual.”

Old Problems in New Media

Not all discrimination is so overt. A study summarized on the Harvard Business Review website analyzed social patterns on Twitter, where female users actually outnumbered males by 10%. The researchers reported “that an average man is almost twice [as] likely to follow another man [as] a woman” while “an average woman is 25% more likely to follow a man than a woman.” The results could not be explained by varying usage since both genders tweeted at the same rate.

Online as off, men are assumed to be more authoritative and credible, and thus deserving of recognition and support. In this way, long-standing disparities are reflected or even magnified on the Internet.

In his 2008 book The Myth of Digital Democracy, Matthew Hindman, a professor of media and public affairs at George Washington University, reports that of the top 10 blogs, only one belonged to a female writer. A wider census of every political blog with an average of over 2,000 visitors a week, or a total of 87 sites, found that only five were run by women, nor were there “identifiable African Americans among the top 30 bloggers,” though there was “one Asian blogger, and one of mixed Latino heritage.” In 2008, Hindman surveyed the blogosphere and found it less diverse than the notoriously whitewashed op-ed pages of print newspapers. Nothing suggests that, in the intervening six years, things have changed for the better.

Welcome to the age of what Julia Carrie Wong has called “old problems in new media,” as the latest well-funded online journalism start-ups continue to be helmed by brand-name bloggers like Ezra Klein and Nate Silver. It is “impossible not to notice that in the Bitcoin rush to revolutionize journalism, the protagonists are almost exclusively -- and increasingly -- male and white,” Emily Bell lamented in awidely circulated op-ed. It’s not that women and people of color aren’t doinginnovative work in reporting and cultural criticism; it’s just that they get passed over by investors and financiers in favor of the familiar.

As Deanna Zandt and others have pointed out, such real-world lack of diversity is also regularly seen on the rosters of technology conferences, even as speakers take the stage to hail a democratic revolution on the Web, while audiences that look just like them cheer. In early 2013, in reaction to the announcement of yet another all-male lineup at a prominent Web gathering, a pledge was posted on the website of the Atlantic asking men to refrain from speaking at events where women are not represented. The list of signatories was almost immediately removed “due to a flood of spam/trolls.” The conference organizer, a successful developer, dismissed the uproar over Twitter. “I don’t feel [the] need to defend this, but am happy with our process,” he stated. Instituting quotas, he insisted, would be a “discriminatory” way of creating diversity.

This sort of rationalization means technology companies look remarkably like the old ones they aspire to replace: male, pale, and privileged. Consider Instagram, the massively popular photo-sharing and social networking service, which was founded in 2010 but only hired its first female engineer last year. While the percentage of computer and information sciences degrees women earned rose from 14% to 37% between 1970 and 1985, that share had depressingly declined to 18% by 2008.

Those women who do fight their way into the industry often end up leaving -- their attrition rate is 56%, or double that of men -- and sexism is a big part of whatpushes them out. “I no longer touch code because I couldn't deal with the constant dismissing and undermining of even my most basic work by the ‘brogramming’ gulag I worked for,” wrote one woman in a roundup of answers to the question: Why there are so few female engineers?

In Silicon Valley, Facebook’s Sheryl Sandberg and Yahoo’s Marissa Mayer excepted, the notion of the boy genius prevails.  More than 85% of venture capitalists are men generally looking to invest in other men, and women make 49 cents for every dollar their male counterparts rake in -- enough to make a woman long for the wage inequities of the non-digital world, where on average they take home a whopping 77 cents on the male dollar. Though 40% of private businesses are women-owned nationwide, only 8% of the venture-backed tech start-ups are.

Established companies are equally segregated. The National Center for Women and Information Technology reports that in the top 100 tech companies, only 6% of chief executives are women. The numbers of Asians who get to the top are comparable, despite the fact that they make up one-third of all Silicon Valley software engineers. In 2010, not even 1% of the founders of Silicon Valley companies were black.

Making Your Way in a Misogynist Culture

What about the online communities that are routinely held up as exemplars of a new, networked, open culture? One might assume from all the “revolutionary” and “disruptive” rhetoric that they, at least, are better than the tech goliaths. Sadly, the data doesn’t reflect the hype. Consider Wikipedia. A survey revealed that women make up less than 15% of the contributors to the site, despite the fact that they use the resource in equal numbers to men.

In a similar vein, collaborative filtering sites like Reddit and Slashdot, heralded by the digerati as the cultural curating mechanisms of the future, cater to users who are up to 87% male and overwhelmingly young, wealthy, and white. Reddit, in particular, has achieved notoriety for its misogynist culture, with threads where rapists have recounted their exploits and photos of underage girls got posted under headings like “Chokeabitch,” “Niggerjailbait,” and “Creepshots.”

Despite being held up as a paragon of political virtue, evidence suggests that as few as 1.5% of open source programmers are women, a number far lower than the computing profession as a whole. In response, analysts have blamed everything from chauvinism, assumptions of inferiority, and outrageous examples of impropriety (including sexual harassment at conferences where programmers gather) to a lack of women mentors and role models. Yet the advocates of open-source production continue to insist that their culture exemplifies a new and ethical social order ruled by principles of equality, inclusivity, freedom, and democracy.

Unfortunately, it turns out that openness, when taken as an absolute, actually aggravates the gender gap. The peculiar brand of libertarianism in vogue within technology circles means a minority of members -- a couple of outspoken misogynists, for example -- can disproportionately affect the behavior and mood of the group under the cover of free speech. As Joseph Reagle, author of Good Faith Collaboration: The Culture of Wikipediapoints out, women are not supposed to complain about their treatment, but if they leave -- that is, essentially are driven from -- the community, that’s a decision they alone are responsible for.

“Urban” Planning in a Digital Age

The digital is not some realm distinct from “real” life, which means that the marginalization of women and minorities online cannot be separated from the obstacles they confront offline. Comparatively low rates of digital participation and the discrimination faced by women and minorities within the tech industry matter -- and not just because they give the lie to the egalitarian claims of techno-utopians. Such facts and figures underscore the relatively limited experiences and assumptions of the people who design the systems we depend on to use the Internet -- a medium that has, after all, become central to nearly every facet of our lives.

In a powerful sense, programmers and the corporate officers who employ them are the new urban planners, shaping the virtual frontier into the spaces we occupy, building the boxes into which we fit our lives, and carving out the routes we travel. The choices they make can segregate us further or create new connections; the algorithms they devise can exclude voices or bring more people into the fold; the interfaces they invent can expand our sense of human possibility or limit it to the already familiar.

What vision of a vibrant, thriving city informs their view? Is it a place that fosters chance encounters or does it favor the predictable? Are the communities they create mixed or gated? Are they full of privately owned shopping malls and sponsored billboards or are there truly public squares? Is privacy respected? Is civic engagement encouraged? What kinds of people live in these places and how are they invited to express themselves? (For example, is trolling encouraged, tolerated, or actively discouraged or blocked?)

No doubt, some will find the idea of engineering online platforms to promote diversity unsettling and -- a word with some irony embedded in it -- paternalistic, but such criticism ignores the ways online spaces are already contrived with specific outcomes in mind.  They are, as a start, designed to serve Silicon Valley venture capitalists, who want a return on investment, as well as advertisers, who want to sell us things. The term “platform,” which implies a smooth surface, misleads us, obscuring the ways technology companies shape our online lives, prioritizing certain purposes over others, certain creators over others, and certain audiences over others.

If equity is something we value, we have to build it into the system, developing structures that encourage fairness, serendipity, deliberation, and diversity through a process of trial and error. The question of how we encourage, or even enforce, diversity in so-called open networks is not easy to answer, and there is no obvious and uncomplicated solution to the problem of online harassment. As a philosophy, openness can easily rationalize its own failure, chalking people’s inability to participate up to choice, and keeping with the myth of the meritocracy, blaming any disparities in audience on a lack of talent or will.

That’s what the techno-optimists would have us believe, dismissing potential solutions as threats to Internet freedom and as forceful interference in a “natural” distribution pattern. The word “natural” is, of course, a mystification, given that technological and social systems are not found growing in a field, nurtured by dirt and sun. They are made by human beings and so can always be changed and improved.

DNA

With technology reminiscent of Jurassic Park, scientists plan to revive long-extinct species like the passenger pigeon.

The practice of cloning has long been stigmatized. Although the potential benefits have yet to be definitively weighed against the possible ethical repercussions, according to National Geographic, a technology called de-extinction is now within reach.

In the past decade alone, scientific tools and procedures have improved so that the idea of successfully cloning animals has moved from a vague fantasy to a tenable reality. Environmentalist Stewart Brand has been researching the possibility of bringing back the passenger pigeon, a species hunted to extinction in 1914. Ben Novak is a genetics student heading up the passenger pigeon research for environmentalist Stewart Brand’s Revive & Restore organization. “We’re going to build from scratch the code that is a passenger pigeon, one gene at a time, [and] compare it to its closest relative. Then we’re going to introduce DNA into the living cell of a Band-tailed pigeon,” he explains in a video from TIME Magazine. “When you introduce an extinct animal’s egg cell into a new mother, then you’ve changed the game, which has been done.”

Novak is referring to past attempts to clone the Pyrenean ibex. In 2003, Spanish and French reproductive physiologists were able to revive the cells of the extinct goat. The team used the preserved cells of the last ibex, who had died in 1989, to inject nuclei into goat eggs and implant the eggs in surrogate mothers. Few implantations resulted in pregnancies, and most pregnancies ended in miscarriage. However, one birth resulted in a clone of the Pyrenean ibex. The animal was born with respiratory defects and died within ten minutes, a short-lived and bittersweet first success at de-extinction.

Although technology has much improved since 2003, the revival of a once-extinct species is still years away and would only be possible for species that died out within the past couple tens of thousands of years. The events of Jurassic Park will not be relived any time soon. However, with the current advances in biotechnology, both scientists and the public may soon have to question whether bringing back extinct species is a reality they are willing to face. “One of the things we’ve gotten used to is the horrifying realization that extinction is forever,” Brand says. “But what if the new truth is that de-extinction is forever?”

Of course, there are several issues to work past before de-extinction becomes widely accepted. Revived species would be living in an environment vastly different from the one they inhabited before extinction, and the possibility of new diseases rapidly wiping them out is a real possibility. Protestors call the technology an expensive distraction from the more pressing matter of dwindling populations of living species. Since many of these species were killed through human interference and hunting, questions of whether the world is even ready to welcome these species back have been raised.

Supporters of de-extinction counter these reservations with suggestions of increased biological diversity and benefits to medical studies. With further research, the expenses of biotechnology should decrease rapidly. Scientists can research the protection of nearly extinct species while working on de-extinction, and as Church points out, “It’s hard to say in advance what’s distraction and what’s salvation.” As far as the complaints that scientists are attempting to play God or meddle unnecessarily, Novak says, “It was our direct activity that caused that extinction. For me, biotech is the future of conservation, because our meddling is not unnatural. It is what species do.”

DNA barcoding art

Easy enough for kids and amateur scientists to use, you might say DNA barcoding is inherently democratic.

In 2008, I happened to see an intriguing news story about two New York City high school girls who had used a new DNA-based identification method to determine if their neighborhood sushi restaurants were selling mislabeled fish. That was my first encounter with the technique known as DNA barcoding. Since then, I have helped hundreds of amateur scientists use barcoding to question the identity of everything from 'heirloom' oranges to 'beef' meatballs to the diversity of Alaskan plants.

The idea of identifying species through a very short genetic sequence, rather like the manner in which a supermarket barcode identifies products, was first proposed in a 2003 paper by Dr. Paul Hebert, a researcher at the University of Guelph in Ontario, Canada. The beauty of barcoding is that even non-specialists can obtain barcodes from tiny amounts of tissue and conclusively identify a species. Compare this to standard taxonomic identification, which requires intact specimens (often impossible in situations where you want to know the identity of foodstuffs) and an expert able to distinguish subtle anatomical differences between closely-related species using morphological features like the shape and color of the organism's parts. As The New York Times put it in their article about the abovementioned 'SushiGate' kids:

"What may be most impressive about the experiment is the ease with which the students accomplished it. Although the testing technique is at the forefront of research, the fact that anyone can take advantage of it by sending samples off to a laboratory meant the kind of investigative tools once restricted to Ph.D.'s and crime labs can move into the hands of curious diners and amateur scientists everywhere."

Readers of GeneWatch are probably more aware than most of the astounding rate at which DNA science in general is progressing. What they may not know is that there is a growing movement to democratize the technology, to put it into the hands of the public for the greater good. Professional scientists like myself have been inspired to found open, public-serving laboratories that are accessible to anyone who wants to pursue a safe and useful project. Genspace, which I co-founded and direct, is a nonprofit community biolab located in Brooklyn, NY. We provide workspace, access to equipment, and mentorship in the biosciences. Genspace offers adult education courses, free public events such as open barcoding nights, low-cost lab space for inventors, and is a place for students to work on projects for science competitions. One of the best uses of community labs is the kind of DIY investigation that can tell you more about your environment, health, or food. Is that goat cheese made with cow's milk? Bring it in and we'll teach you to barcode it. Want to know if your soy milk is Roundup Ready? We can teach you to determine that too, it's an even simpler protocol than barcoding. We want everyone to become more literate in the biosciences in order to join the discussion about them from a position of knowledge as opposed to forming opinions based on ignorance and fear. And I strongly feel that the best way to learn is hands-on in the lab.

Barcoding is a regular activity at Genspace. It's a great way for amateurs to participate in real science. Although the DNA barcodes of most common species have been deposited into public databases, most of the millions of species on earth have not been barcoded yet. This gives the student or citizen scientist an opportunity to contribute to the growing public database of DNA barcodes. Genspace first began teaching barcoding as part of Cold Spring Harbor Laboratory's 2011-2012 Urban Barcode Project, a science competition for high school students. Genspace worked closely with their Harlem DNA Lab and acted as its satellite site in Brooklyn for teacher training and open lab hours to mentor students in barcoding, a relationship that continues today.

Our newest barcoding project focuses on the importance of identifying organisms to help monitor the biological effects of global climate change. Accelerating habitat destruction is particularly evident in the Alaskan landscape, where glaciers recede practically before our eyes and environmentalists attempt to preserve species diversity in the face of opposing economic interests. In Genspace's Alaska Barcode Project, we invite the general public to monthly open nights where we teach them to barcode plant samples collected from remote locations in interior Alaska.  The goal is twofold: to create a baseline survey of plants in particular areas such as the Skolai Valley in Wrangell-St. Elias National Park, and to add new identifying barcodes to the Barcode of Life Database to empower future amateur scientists to conduct similar surveys.

Part of the DNA sequence of the chloroplast gene rbcL has been designated as one of the two barcode regions for plants (the matK gene is the other region but is not used at Genspace). Barcoding a specimen starts with extracting its DNA. You only need a small piece, the diameter of a pencil eraser, to get plenty of DNA for barcoding. In a tiny plastic tube, the sample is mixed with a few drops of a solution that disrupts the cellular structure and then ground into a paste using a little plastic pestle. The DNA is then absorbed onto silica, which is washed with salt-containing buffers until all other cellular components are gone. The clean DNA is eluted off the silica with water and the barcoding region amplified using a procedure called polymerase chain reaction (PCR). The amplification is necessary to get enough material in the tube to send out for sequencing.

PCR is a standard lab technique that has become mostly automated. Prepackaged mixtures of enzymes and reaction components such as the PCR primers that target the barcoding region can be bought cheaply in bulk. All one has to do is add a minute quantity of your DNA to the PCR mix and stick it into a preprogrammed machine. What comes out is ready to be sent off for sequencing at a fee-for-service facility doing hundreds of sequencing reactions daily. The total cost for the whole procedure can be less than $20 per sample.

Our barcoding nights have been very popular. They educate people and make them more informed about cutting-edge science. There is also a social component to the project where participants often engage in discussions about the promise and the repercussions of the technology.

It wasn't that long ago that major scientific contributions were made by curious amateurs, and science itself was less of a profession and more of a hobby. The popularity of our barcoding nights might be predictive of the resurgence of such citizen science, where a diverse cross-section of the general population are enthusiastic participants in scientific inquiry. It's empowering to be able to use the latest breakthroughs to answer questions of importance to you. I can think of no better use of my time than to continue to facilitate this empowerment through my work at Genspace. And please do stop by and barcode something if you are in the neighborhood!

arctic cod

Arctic Cod may hold the key to a more efficient method for storing blood.

Maintaining an adequate supply of blood has always been a challenge for hospitals. While refrigeration and freezing can provide a blood bank with reserves, the limited shelf life of blood and the additives used for preservation have made blood storage far from efficient, and reliance on new donors perpetual. But a new study conducted by scientists at the University of Warwick has demonstrated that nature might have a solution.

Summarized by Peter Dunn-Warwick for Futurity and first published in the journal Nature Communications, the study took a closer look at the antifreeze properties of fish that live in sub-freezing waters such as the arctic cod. Scientists isolated the specific proteins that prohibit freezing in fish blood, and were able to mimic the properties of those proteins in a polymer alcohol that can be added to human blood for efficient storage. Matthew Gibson of the University of Warwick summed up the multiple benefits of using polymer alcohol in freezing blood: “Firstly, it reduces the growth of ice crystals during thawing, secondly it reduces the need for organic solvents, and crucially, it reduces the time between defrosting and having transfusion-ready blood by eliminating the need to remove solvent.”

Although further testing is needed, scientists are hopeful that polymer alcohol will not only enhance blood storage techniques, but also bolster treatments for certain cancers and neurological ailments.

 EEG headset

New advancements in EEG technology allow the average consumer to unleash their inner Jedi via headset.

The ability to influence objects with sheer brain power has typically been designated to the realm of science fiction, but new advancements in EEG technology allow the average consumer to gain insight into the inner workings of their mind via headset. EEG, which stands for electroencephalography, is a tool used in neuroscience to pick up patterns in the brain’s electrical activity, such as those that occur while sleeping or during epileptic seizures. EEGs have been used in hospitals to detect epilepsy and monitor the activity caused by other brain conditions, but recent efforts have been made to pair affordable EEG headsets with products such as computer programs, cell phones, toys, and video games in order to develop mental control and relaxation. Many of these products are being offered within an open source model, allowing users to further develop and experiment with EEG technology at home.

Amy Standen of KQED Science reports that NeuroSky’s MindWave Mobile EEG headset costs only around $100 and is powered by a single AAA battery. Paired with the Puzzlebox Orbit Brain-Controlled Helicopter (priced at $89), the headset measures attention levels by requiring users to clear their thoughts and focus their concentration to power the helicopter while infrared signals on the gadget guide its flight. Richard and Erica Warp combined their knowledge of composing and neuroscience to develop another use for EEG headsets, the NeuroDisco computer program. The program composes music based on the brainwaves read from sixteen sensors placed around the scalp—the more focused you are, the more pleasant the notes produced.

This type of instant feedback allows users to understand how the brain influences certain results and subsequently alter their way of thinking to achieve change. As Adam Gazzaley of the University of California-San Francisco tells Standen, EEG programs may even help those diagnosed with ADHD. “Instead of being given a box of pills, they put an EEG cap on and they play a video game that looks at how they pay attention to relevant information, how they ignore information, how they sustain attention, how they deal with multiple tasks,” Gazzaley suggests. Then, devices such as the brain-controlled helicopter could provide an entertaining method of developing focus and mental relaxation. The affordability of EEG headsets will hopefully lead to further innovative uses of its potential and the continuing effort to bring such technology out of the hospital and into the hands of the everyday consumer.

oru kayak

The Oru Kayak aims to sustainably and affordably reconnect urbanites with the natural world around them.

The collapsible boat marketed to urbanites is not a new idea. But one California inventor and entrepreneur might have found the perfect combination of efficiency, sustainability, and affordability with his improvement on the collapsible kayak, reports Pat Joseph in the Summer 2013 issue of California.

Inspired by origami, Oru Kayak founder Anton Willis has successfully developed an all- plastic boat that’s fully recyclable, extremely durable, and able to be folded into its carrying case that can be stored in a closet or under the bed. It can withstand the folding/unfolding process up to 20,000 times, but most importantly, it actually works, and has been positioned as the ideal water vehicle for the urban dweller who’s interested in exploring their city’s waterways. And while Willis doesn’t recommend it for the weekend warrior, the Oru Kayak is even durable enough to handle the choppy waters of San Francisco Bay, demonstrating that it’s capable of handling pretty much any scenario an urban boater might come across:

As Joseph explains in his article, the Oru Kayak represents a new breed of collapsible boats as it’s lighter than comparable boats (it’s just about 25 pounds), more compact, and cheaper (the boat alone sells for $1,095). A successful Kickstarter campaign in 2012 got the ball rolling in a big way, proving that there was hungry market for Willis’ idea.

But the physical attributes of the boat only tell part of the story as far as Willis is concerned. From a philosophical perspective, this boat represents another extension of the mission at the heart of every project Willis has taken on; that is, his heartfelt desire to help urban people reconnect with the natural surroundings that are so easy for urbanites to miss or take for granted. His company’s product tester, Roberto Gutierrez, summed up Willis’ drive by saying, “For Anton, it’s not so much about selling stuff; it’s about getting people in boats and exploring the world around them. If selling Oru Kayaks can accomplish that, I think he’s happy.”

the baths of caracalla

Scientific analysis of ancient Roman concrete suggests it was stronger, more durable, and more environmentally sound than modern concrete.

The simple fact that we can still visit the buildings and monuments of the ancient Romans illustrates that they knew what they were doing when it came to developing long-lasting building materials. Many historians even credit the Romans with inventing what we call concrete through their use of a very simple process:

But as Conservation reports in its Fall 2013 issue, it’s only recently that scientists have broken down the structure, chemical composition, and mechanical properties of ancient Roman concrete to the point of being able to glean useful information for contemporary concrete production.

Researchers from the University of California, Berkeley, summarized their findings in the Journal of the American Ceramic Society, and found the ancient Roman combination of limestone, volcanic ash, and seawater required far less heat (which means far less fuel) for solidification than modern concrete does. This suggests that contemporary application of the ancient Roman method may yield stronger, more durable concrete with a much smaller environmental footprint.
