Scary but coming from Microsoft
[...] The new Connected Car will know its riders, and will interact with them naturally via speech, gestures, and face tracking. It will learn their habits, and offer personalized contextual information and driving assists to get them to their destination as quickly and safely as possible. Through a growing catalogue of applications, it will inform and entertain them, and keep them connected with the people and information they care about. The possibilities are endless.

Next step, Newt Gingrich
By John Roach
After six years and several million dollars, scientists have created a 3-D model of a rat brain circuit.
The accomplishment is a first step toward creating a complete computer
model of the brain that will allow a deeper understanding of how our
noggins work — and what causes them to malfunction, according to the
scientists behind the feat.
For a starting point, researchers at the Max Planck Florida Institute are focused on how the rat brain processes information gathered by a single whisker.
They did so because studies in their lab and elsewhere
have shown that a single whisker is able to detect, in complete
darkness, whether a gap is safe to jump over and, if so, trigger the
order to jump.
What's more, there's a specific region of the
brain "that is dedicated to processing information from a dedicated
whisker," Marcel Oberlaender, a researcher at the institute and the
first author of a paper explaining the research in the journal Cerebral Cortex, told me today.
That
region is called the cortical column, a vertically-organized series of
connected neurons that form a brain circuit and an elementary building
block of the cortex.
The cortex is the part of the brain responsible for many of the higher functions, such as memory and consciousness.
To
build the model, the researchers studied the cortical column in awake
and anesthetized rats as well as brain slices and then used computer software and other tools to reconstruct it.
"The
model we built is really based on a complete reconstruction of these
nerve cells," Oberlaender said. "So how the model looks in the end
resembles how it would look in the real animal."
It is composed of
16,000 neurons, each of which can be divided into one of nine different
cell types that has characteristic functional, structural and
connectivity properties, he added.
The model can now be used to
run computer simulations that show, in realistic detail, how signals
flow within the brain. So, they can begin to understand, for example,
what neurons fire as the rat detects the gap and decides whether or not
to jump.
Until now, researchers have only been able to see how a
single neuron or a small group of neurons interact during such a
process. "We can now, in simulation experiments, mimic what is really
going on in these circuits," Oberlaender said.
Going forward, the
researchers should be able to use the methodology developed to build
this model to add more parts to it, thus incorporating other brain
functions such as the motor system that sends a signal down the spinal
cord and makes the limbs move so that rat can jump over the gap.

A bit of history > eBook Tops All Trade Publishing Categories in February
By Jason Boog on April 14, 2011 3:47 PM
eBook sales totaled $90.3 million for the month, expanding 202 percent compared to the same period last year. Below, we’ve embedded the full release.
Here’s more from the AAP: “This one-month surge is primarily attributed to a high level of strong post-holiday e-Book buying, or ‘loading,’ by consumers who received e-Reader devices as gifts. Experts note that the expanded selection of e-Readers introduced for the holidays and the broader availability of titles are factors.”

Discovery News > Resort attracts men with virtual girlfriends
Sad, sick, weird, funny or what? I dunno.
A resort in Japan is offering young men a tourism destination to frolic with their virtual girlfriends. The resort is based on a game called "Love Plus," which encourages players to develop long-term relationships with virtual women. Read the rest of this story here.

Wired > Gadget Lab > Robotic Eye
The eye has a transparent-plastic inner sphere with a set of magnets around it, painted to look just like a human eye. It is suspended in fluid and has a transparent outer shell. Using electromagnets from the outside, the eye is moved sideways or up and down, giving it a smooth and easy motion. “It is as fast as the human eye and as good as the human eye." The pupil and the back of the eye are clear. A camera placed at the rear of the eye helps the eye see. Read more here
