PSFK: “Because most of us only see the finished product when it comes to 3D printing projects – it’s easy to forget that things can, and do, go wrong when it comes to this miracle technology.
3D printing is constantly evolving, reaching exciting new heights, and touching every industry you can think of – but all this progress has left a trail of mangled plastic, and a devastated machines in it’s wake.
The Art of 3D Print Failure is a Flickr group that aims to document this failure, because after all, mistakes are how we learn, and how we make sure the same thing doesn’t happen the next time around. It can also prevent mistakes from happening to those who are new to 3D printing, before they even make them!”
Manipulation Among the Arbiters of Collective Intelligence: How Wikipedia Administrators Mold Public Opinion
New paper by Sanmay Das, Allen Lavoie, and Malik Magdon-Ismail: “Our reliance on networked, collectively built information is a vulnerability when the quality or reliability of this information is poor. Wikipedia, one such collectively built information source, is often our first stop for information on all kinds of topics; its quality has stood up to many tests, and it prides itself on having a “Neutral Point of View”. Enforcement of neutrality is in the hands of comparatively few, powerful administrators. We find a surprisingly large number of editors who change their behavior and begin focusing more on a particular controversial topic once they are promoted to administrator status. The conscious and unconscious biases of these few, but powerful, administrators may be shaping the information on many of the most sensitive topics on Wikipedia; some may even be explicitly infiltrating the ranks of administrators in order to promote their own points of view. Neither prior history nor vote counts during an administrator’s election can identify those editors most likely to change their behavior in this suspicious manner. We find that an alternative measure, which gives more weight to influential voters, can successfully reject these suspicious candidates. This has important implications for how we harness collective intelligence: even if wisdom exists in a collective opinion (like a vote), that signal can be lost unless we carefully distinguish the true expert voter from the noisy or manipulative voter.”
Smartphones As Weather Surveillance Systems
Tom Simonite in MIT Technology Review: “You probably never think about the temperature of your smartphone’s battery, but it turns out to provide an interesting method for tracking outdoor air temperature. It’s a discovery that adds to other evidence that mobile apps could provide a new way to measure what’s happening in the atmosphere and improve weather forecasting.
Startup OpenSignal, whose app crowdsources data on cellphone reception, first noticed in 2012 that changes in battery temperature correlated with those outdoors. On Tuesday, they published a scientific paper on that technique in a geophysics journal and announced that the technique will be used to interpret data from a weather crowdsourcing app. OpenSignal originally started collecting data on battery temperatures to try and understand the connections between signal strength and how quickly a device chews through its battery.
OpenSignal’s crowdsourced weather-tracking effort joins another accidentally enabled by smartphones. A project called PressureNET that collects air pressure data by taking advantage of the fact many Android phones have a barometer inside to aid their GPS function (see “App Feeds Scientists Atmospheric Data From Thousands of Smartphones”). Cliff Mass, an atmospheric scientist at the University of Washington, is working to incorporate PressureNET data into weather models that usually rely on data from weather stations. He believes that smartphones could provide valuable data from places where there are no weather stations, if enough people start sharing data using apps like PressureNET.
Other research suggests that logging changes in cell network signal strength perceived by smartphones could provide yet more weather data. In February researchers in the Netherlands produced detailed maps of rainfall compiled by monitoring fluctuations in the signal strength measured by cellular network masts, caused by water droplets in the atmosphere.”
We the People Update
Washington Post: “The White House launched the We The People petition site in 2011 as a way for Americans to get their government to respond to their calls for action. On the digital platform, people can create and sign petitions seeking specific action on an issue from the federal government. In theory, once a petition has garnered a certain number of signatures within a certain time frame, it is reviewed by White House staff and receives an official response.
But that’s not always what happens.
Now a new site, www.whpetitions.info, takes its own tally and highlights petitions that have received enough signatures but have not received responses. By its count, the White House has responded to 87 percent of petitions that have met their signature thresholds with an average response time of 61 days. But the average waiting time so far for the 30 unanswered petitions is 240 days. And six of them have been waiting for over a year.”
Behold: A Digital Bill of Rights for the Internet, by the Internet
Mashable: “The digital rights conversation was thrust into the mainstream spotlight after news of ongoing, widespread mass surveillance programs leaked to the public. Always a hot topic, these revelations sparked a strong online debate among the Internet community.
It also made us here at Mashable reflect on the digital freedoms and protections we feel each user should be guaranteed as a citizen of the Internet. To highlight some of the great conversations taking place about digital rights online, we asked the digital community to collaborate with us on the creation of a crowdsourced Digital Bill of Rights.
After six weeks of public discussions, document updates and changes, as well as incorporating input from digital rights experts, Mashable is pleased to unveil its first-ever Digital Bill of Rights, made for the Internet, by the Internet.”
Data is Inert — It’s What You Do With It That Counts
Kevin Merritt, CEO and Founder, Socrata, in NextGov: “In its infancy, the open data movement was mostly about offering catalogs of government data online that concerned citizens and civic activists could download. But now, a wide variety of external stakeholders are using open data to deliver new applications and services. At the same time, governments themselves are harnessing open data to drive better decision-making.
In a relatively short period of time, open data has evolved from serving as fodder for data publishing to fuel for open innovation.
One of the keys to making this transformation truly work, however, is our ability to re-instrument or re-tool underlying business systems and processes so managers can receive open data in consumable forms on a regular, continuous basis in real-time….”
Social Influence Bias: A Randomized Experiment
New paper in Science: “Our society is increasingly relying on the digitized, aggregated opinions of others to make decisions. We therefore designed and analyzed a large-scale randomized experiment on a social news aggregation Web site to investigate whether knowledge of such aggregates distorts decision-making. Prior ratings created significant bias in individual rating behavior, and positive and negative social influences created asymmetric herding effects. Whereas negative social influence inspired users to correct manipulated ratings, positive social influence increased the likelihood of positive ratings by 32% and created accumulating positive herding that increased final ratings by 25% on average. This positive herding was topic-dependent and affected by whether individuals were viewing the opinions of friends or enemies. A mixture of changing opinion and greater turnout under both manipulations together with a natural tendency to up-vote on the site combined to create the herding effects. Such findings will help interpret collective judgment accurately and avoid social influence bias in collective intelligence in the future.”

A Videogame That Recruits Players to Map the Brain
Wired: “I’m no neuroscientist, and yet, here I am at my computer attempting to reconstruct a neural circuit of a mouse’s retina. It’s not quite as difficult and definitely not as boring as it sounds. In fact, it’s actually pretty fun, which is a good thing considering I’m playing a videogame.
Called EyeWire, the browser-based game asks players to map the connections between retinal neurons by coloring in 3-D slices of the brain. Much like any other game out there, being good at EyeWire earns you points, but the difference is that the data you produce during gameplay doesn’t just get you on a leader board—it’s actually used by scientists to build a better picture of the human brain.
Created by neuroscientist Sebastian Seung’s lab at MIT, EyeWire basically gamifies the professional research Seung and his collaborators do on a daily basis. Seung is studying the connectome, the hyper-complex tangle of connections among neurons in the brain.”
Big data, crowdsourcing and machine learning tackle Parkinson’s
Successful Workingplace: “Parkinson’s is a very tough disease to fight. People suffering from the disease often have significant tremors that keep them from being able to create accurate records of their daily challenges. Without this information, doctors are unable to fine tune drug dosages and other treatment regimens that can significantly improve the lives of sufferers.
It was a perfect catch-22 situation until recently, when the Michael J. Fox Foundation announced that LIONsolver, a company specializing in machine learning software, was able to differentiate Parkinson’s patients from healthy individuals and to also show the trend in symptoms of the disease over time.…
To set up the competition, the Foundation worked with Kaggle, an organization that specializes in crowdsourced big data analysis competitions. The use of crowdsourcing as a way to get to the heart of very difficult Big Data problems works by allowing people the world over from a myriad of backgrounds and with diverse experiences to devote time on personally chosen challenges where they can bring the most value. It’s a genius idea for bringing some of the scarcest resources together with the most intractable problems.”
Can We Build A Kickstarter For Cancer?
Paul Howard in Forbes: “tarting you own band, writing your first novel, or re-publishing your favorite ‘80s tabletop RPG are all cool goals. You can do them all on Kickstarter. What would be cooler?
How about funding a virtual biotech company with one goal: Saving or extending the life of a cancer patient who doesn’t respond to “standard of care” treatments….
The Cancer Commons approach – a distributed framework for empowering patients and learning from every patient/treatment combination – breaks down traditional distinctions between clinical trials and patient treatment in the “real world.” Instead of developing treatments in a lab and then testing them on randomized patients in clinical trials (designed to benefit future patients), researchers would apply the latest scientific knowledge and tools to help each patient achieve the best possible outcome today based on what we know – or think we can predict – about a molecular subtype of cancer….
We’ll need more than money to power a Kickstarter-for-cancer movement. We’ll need to encourage companies – from Big Pharma to “small” biotechs – to participate in distributed, Bayesian trials where new biomarkers or combinations of biomarkers are tested in patients with particular molecular profiles. And the FDA is going to have to be convinced that the system is going to generate high quality data that benefits patients, not sell them snake-oil cures.
In return for companies making their compound libraries and experimental drugs available for the “virtual biotechs” launched by cancer patients and their families, there should be a regulatory path established to take the most promising drugs and drug combinations to market.”
