#MIT launches Laboratory for Social Machines with major Twitter investment The MIT Media Lab today announced the creation of the Laboratory for Social Machines (LSM), funded by a five-year, $10 million

commitment from Twitter. As part of the new program, Twitter will also provide full access to its real-time, public stream of tweets,

as well as the archive of every tweet dating back to the first. The new initiative, based at the Media Lab, will focus on the development of new technologies to make sense of semantic and social patterns across the broad span of public mass media

social media, data streams, and digital content. Pattern discovery and data visualization will be explored to reveal interaction patterns and shared interests in relevant social systems,

Though funded by Twitter, the LSM will have complete operational and academic independence. In keeping with the academic mission of LSM, students and staff will work across many social media

and mass media platforms including, but not limited to, Twitter. he Laboratory for Social Machines will experiment in areas of public communication

and social organization where humans and machines collaborate on problems that can be solved manually or through automation alone, says Deb Roy,

and who also serves as Twitter chief media scientist.""Social feedback loops based on analysis of public media

""With this investment, Twitter is seizing the opportunity to go deeper into research to understand the role Twitter

"says Dick Costolo, CEO of Twitter.""As social media leads us into the emergence of a new era of communication and engagement, the LSM,

in collaboration with Twitter, will create analytical tools to help turn the vision of a new public sphere into reality,

The broad goal is to become the emotion layer of the Internet says Affectiva cofounder Rana el Kaliouby a former MIT postdoc who invented the technology.

Still in their early stages some of the apps are designed for entertainment such as people submitting selfies to analyze their moods and sharing them across social media.

One of Affectiva s long-term goals is to usher in a mood-aware Internet to improve users experiences.

Imagine an Internet that s like walking into a large outlet store with sales representatives el Kaliouby says.

Websites and connected devices of the future should be like this very mood-aware. Sometime in the future this could mean computer games that adapt in difficulty and other game variables based on user reaction.

For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical engineering and Computer science at MIT, has argued that the massively multicore chips of the future will need to resemble little Internets,

where each core has associated an router, and data travels between cores in packets of fixed size.

Groups of declarations reach the routers associated with the cores at discrete intervals intervals corresponding to the time it takes to pass from one end of the shadow network to another.

Each router can thus tabulate exactly how many requests were issued during which interval, and by which other cores.

Core 32 router may receive core 10 request well before it receives core 1 . But it will hold it until it passed along 1. This hierarchical ordering simulates the chronological ordering of requests sent over a bus,

DIG is directed by Tim Berners-Lee the inventor of the Web and the 3com Founders Professor of Engineering at MIT and it shares office space with the World wide web Consortium (W3c) the organization also led by Berners-Lee that oversees the development of Web protocols like HTTP XML and CSS.

DIG s role is to develop new technologies that exploit those protocols. With HTTPA each item of private data would be assigned its own uniform resource identifier (URI) a key component of the Semantic web a new set of technologies championed by W3c that would convert the Web from essentially a collection of searchable

text files into a giant database. Remote access to a Web server would be controlled much the way it is now through passwords and encryption.

But every time the server transmitted a piece of sensitive data it would also send a description of the restrictions on the data s use.

#What exactly is Google's'cancer nanodetector'?'Last week US tech giants Google made a splash in the media announcing plans to develop new'disease-detecting magnetic nanoparticles'.

'This was welcomed almost universally after all trying to detect diseases earlier is something that's a focus of many research organisations including ours.

what Google are actually planning apart from getting a lot of coverage in the media he says.

But then they're Google he says. They do things differently. The way traditional science works is to map out all the possible risks demonstrate you've accounted for them

Google are doing the opposite they're saying'we want to get to here we'll worry about the details later'.

Google have been similarly vague about the precise form of nanotechnology they aim to use Graham points out:

This isn't all about Google says Graham. It's worth pointing out that Google are far from being the only show in town.

There are loads of different research groups looking into what is called collectively'biosensing'continuous monitoring of

it seems according to this article in Wired that Gambhir originally advised Google about nanotechnology. What are the current challenges facing nanodetectors?

So for Google's biomonitor they need to work out how to keep the particles in the body

This is something Google really seem to have ducked in their announcement. We don't need to dwell on it too much

but there's been a lot in the press in the last year about who has access to Google's data and under

what circumstances says Graham referring to reports of Government agencies accessing user data from tech companies like Google and Facebook.

Professor Graham's'take-home'message is that it's a mistake to see Google as the only organisation focusing on nanotechnology to detect disease it's a vibrant active field with incredible potential but still in its early days.
