Based on Facebook and Twitter chatter, it can seem like Ebola is everywhere. Following the first diagnosis of an Ebola case in the United States on Sept. 30, mentions of the virus on Twitter leapt from about 100 per minute to more than 6,000. Cautious health officials have tested potential cases in Newark, Miami Beach and Washington D.C., sparking more worry. Though the patients all tested negative, some people are still tweeting as if the disease is running rampant in these cities. In Iowa the Department of Public Health was forced to issue a statement dispelling social media rumors that Ebola had arrived in the state. Meanwhile there have been a constant stream of posts saying that Ebola can be spread through the air, water, or food, which are all inaccurate claims.
Research scientists who study how we communicate on social networks have a name for these people: the “infected.”

An international team of neuroscientists and robotics engineers have demonstrated the first direct remote brain-to-brain communication between two humans located 5,000 miles away from each other and communicating via the Internet, as reported in a paper recently published in PLOS ONE (open access).
Emitter and receiver subjects with non-invasive devices supporting, respectively, a brain-computer interface (BCI), based on EEG changes, driven by motor imagery (left) and a computer-brain interface (CBI) based on the reception of phosphenes elicited by neuro-navigated TMS (right) (credit: Carles Grau et al./PLoS ONE)
In India, researchers encoded two words (“hola” and “ciao”) as binary strings and presented them as a series of cues on a computer monitor. They recorded the subject’s EEG signals as the subject was instructed to think about moving his feet (binary 0) or hands (binary 1). They then sent the recorded series of binary values in an email message to researchers in France, 5,000 miles away.
There, the binary strings were converted into a series of transcranial magnetic stimulation (TMS) pulses applied to a hotspot location in the right visual occipital cortex that either produced a phosphene (perceived flash of light) or not.
“We wanted to find out if one could communicate directly between two people by reading out the brain activity from one person and injecting brain activity into the second person, and do so across great physical distances by leveraging existing communication pathways,” explains coauthor Alvaro Pascual-Leone, MD, PhD, Director of the Berenson-Allen Center for Noninvasive Brain Stimulation at Beth Israel Deaconess Medical Center (BIDMC) and Professor of Neurology at Harvard Medical School.
A team of researchers from Starlab Barcelona, Spain and Axilum Robotics, Strasbourg, France conducted the experiment. A second similar experiment was conducted between individuals in Spain and France.
“We believe these experiments represent an important first step in exploring the feasibility of complementing or bypassing traditional language-based or other motor/PNS mediated means in interpersonal communication,” the researchers say in the paper.
“Although certainly limited in nature (e.g., the bit rates achieved in our experiments were modest even by current BCI (brain-computer interface) standards, mostly due to the dynamics of the precise CBI (computer-brain interface) implementation, these initial results suggest new research directions, including the non-invasive direct transmission of emotions and feelings or the possibility of sense synthesis in humans — that is, the direct interface of arbitrary sensors with the human brain using brain stimulation, as previously demonstrated in animals with invasive methods.

On the left, the BCI subsystem is shown schematically, including electrodes over the motor cortex and the EEG amplifier/transmitter wireless box in the cap. Motor imagery of the feet codes the bit value 0, of the hands codes bit value 1. On the right, the CBI system is illustrated, highlighting the role of coil orientation for encoding the two bit values. Communication between the BCI and CBI components is mediated by the Internet.

“The proposed technology could be extended to support a bi-directional dialogue between two or more mind/brains (namely, by the integration of EEG and TMS systems in each subject). In addition, we speculate that future research could explore the use of closed mind-loops in which information associated to voluntary activity from a brain area or network is captured and, after adequate external processing, used to control other brain elements in the same subject. This approach could lead to conscious synthetically mediated modulation of phenomena best detected subjectively by the subject, including emotions, pain and psychotic, depressive or obsessive-compulsive thoughts.
“Finally, we anticipate that computers in the not-so-distant future will interact directly with the human brain in a fluent manner, supporting both computer- and brain-to-brain communication routinely. The widespread use of human brain-to-brain technologically mediated communication will create novel possibilities for human interrelation with broad social implications that will require new ethical and legislative responses.”

Information – Entropy by Oliver Reichenstein
Will information technology affect our minds the same way the environment was affected by our analogue technology? Designers hold a key position in dealing with ever increasing data pollution. We are mostly focussed on speeding things up, on making sharing easier, faster, more accessible. But speed, usability, accessibility are not the main issue anymore. The main issues are not technological, they are structural, processual. What we lack is clarity, correctness, depth, time. Are there counter-techniques we can employ to turn data into information, information into knowledge, knowledge into wisdom?

Re-blogged from New Scientist
Glass could soon be used for more than just snapping pics of your lunchtime sandwich. A new game will connect Glass wearers to a virtual ant colony vying for prizes by solving real-world problems that vex traditional crowdsourcing efforts.
Crowdsourcing is most famous for collaborative projects like Wikipedia and "games with a purpose" like FoldIt, which turns the calculations involved in protein folding into an online game. All require users to log in to a specific website on their PC.
The pair have designed a game called Swarm! that puts a Glass wearer in the role of an ant in a colony. Similar to the pheromone trails laid down by ants, players leave virtual trails on a map as they move about. These behave like real ant trails, fading away with time unless reinforced by other people travelling the same route. Such augmented reality games already exist – Google's Ingress, for one – but in Swarm! the tasks have real-world applications.
Swarm! players seek out virtual resources to benefit their colony, such as food, and must avoid crossing the trails of other colony members. They can also monopolise a resource pool by taking photos of its real-world location.
To gain further resources for their colony, players can carry out real-world tasks. For example, if the developers wanted to create a map of the locations of every power outlet in an airport, they could reward players with virtual food for every photo of a socket they took. The photos and location data recorded by Glass could then be used to generate a map that anyone could use. Such problems can only be solved by people out in the physical world, yet the economic incentives aren't strong enough for, say, the airport owner to provide such a map.
Estrada and Lawhead hope that by turning tasks such as these into games, Swarm! will capture the group intelligence ant colonies exhibit when they find the most efficient paths between food sources and the home nest.
