#Algorithms could adjust screens to your vision University of California Berkeley Original Studyposted by Sarah Yang-Berkeley on August 15 2014.
Researchers are developing vision-correcting displays for computer monitors that would let people see text and images clearly without their glasses or contact lenses.
More importantly the displays could one day aid people with more complex visual problems known as high order aberrations
and vision science and affiliate professor of optometry at University of California Berkeley. e now live in a world where displays are ubiquitous
and being able to interact with displays is taken for grantedsays Barsky who is leading this project. eople with higher order aberrations often have irregularities in the shape of the cornea
because many workers need to look at a screen as part of their work. he UC Berkeley researchers
and Ramesh Raskar colleagues at the Massachusetts institute of technology to develop their latest prototype of a vision-correcting display.
The setup adds a printed pinhole screen sandwiched between two layers of clear plastic to an ipod display to enhance image sharpness.
when the intended user looks at the screen the image will appear sharp to that particular viewersays Barsky. ut
This latest approach improves upon earlier versions of vision-correcting displays that resulted in low-contrast images.
The new display combines light field display optics with novel algorithms. Huang now a software engineer at Microsoft corp. in Seattle notes that the research prototype could easily be developed into a thin screen protector
and that continued improvements in eye-tracking technology would make it easier for the displays to adapt to the position of the user s head position. n the future we also hope to extend this application to multi-way correction on a shared display
so users with different visual problems can view the same screen and see a sharp imagesays Huang.

It should provide us with new insights into how rhythmic brain activity supports core memory processes.
Their strategy was to enable certain synapses to share hardware circuits. The result was called a device Neurogrid.
Their HICANN chiphort for High Input Count Analog Neural Networkould be the core of a system designed to accelerate brain simulations
with a roadmap to greatly expand that hardware base. Each of these research teams has made different technical choices,
such as whether to dedicate each hardware circuit to modeling a single neural element (e g.,, a single synapse) or several (e g.,
, by activating the hardware circuit twice to model the effect of two active synapses. These choices have resulted in different trade-offs in terms of capability and performance.
With that cheaper hardware and compiler software to make it easy to configure, these neuromorphic systems could find numerous applications.

This suggests an ancient conservation in genetic and neural architectures involved in social information processing that transcends the sensory modalities used from mouse to man.
but computer software and hardware are not like that. They often compute to the same level of accuracy all the time. urdue researchers have developed a range of hardware techniques to demonstrate approximate computing showing a potential for improvements in energy efficiency.

The new motor has a core and two arms made of DNA one above and one below the core.
As it moves along a carbon-nanotube track it continuously harvests energy from strands of RNA molecules vital to a variety of roles in living cells
The core is made of an enzyme that cleaves off part of a strand of RNA. After cleavage the upper DNA arm moves forward binding with the next strand of RNA
The generators can be made from nearly transparent polymers allowing their use in touch pads and screens.
#3d printed loudspeaker plays Obama speech The first 3d printed consumer electronic is a loudspeaker that comes out of the printer ready to use.
Lipson says he hopes this simple demonstration is just the ip of the iceberg. 3d printing technology could be moving from printing passive parts toward printing active integrated systems he adds.
Most printers cannot efficiently handle multiple materials. It s also difficult to find mutually compatible materialsâ##for example conductive copper
and plastic coming out of the same printer require different temperatures and curing times. In the case of the speaker Kiran used one of the lab s Fab@Homes a customizable research printer originally developed by Lipson

#Earth s inner core spins faster than rest of planet University of Leeds rightoriginal Studyposted by Ben Jones-U. Leeds on September 17 2013the Earth s
inner core made up of solid iron uperrotatesin an eastward direction while the outer core comprising mainly molten iron spins westwards at a slower pace.
Although Edmund Halley who also discovered the famous comet showed the westward-drifting motion of the Earth s geomagnetic field in 1692 it is the first time that scientists have been able to link the way the inner core spins to the behavior of the outer core.
The planet behaves in this way because it is responding to the Earth s geomagnetic field.
The findings published in the Proceedings of the National Academy of Sciences help scientists to interpret the dynamics of the core of the Earth the source of our planet s magnetic field.
In the last few decades seismometers measuring earthquakes travelling through the Earth s core have identified an eastwards
or superrotation of the solid inner core relative to Earth s surface. he link is explained simply in terms of equal and opposite actionsays Philip Livermore of the School of Earth
and Environment at the University of Leeds. he magnetic field pushes eastwards on the inner core causing it to spin faster than the Earth
but it also pushes in the opposite direction in the liquid outer core which creates a westward motion. he solid iron inner core is about the size of the Moon.
It is surrounded by the liquid outer core an iron alloy whose convection-driven movement generates the geomagnetic field.
The fact that the Earth s internal magnetic field changes slowly over a timescale of decades means that the electromagnetic force responsible for pushing the inner and outer cores will itself change over time.
This may explain fluctuations in the predominantly eastwards rotation of the inner core a phenomenon reported for the last 50 years by Tkalä iä#et al. in a recent study published in Nature Geoscience.
Viewed within the conclusions of the new model this suggests that the inner core may have undergone a westwards rotation in such periods.
Using a new method they were able to simulate the Earth s core with an accuracy about 100 times better than other models.
#Ink-jet printing creates soft nanostructures A new way to make nanostructures combines advanced ink-jet printing technology with block copolymers that spontaneously form ultra-fine structures.
Recently developed ultra high-resolution ink jet printing techniques have some potential with demonstrated resolution down to 100-200 nanometers
Combining jet printing with self-assembling block copolymers enabled the engineers to attain the much higher resolution as suggested by lead author Serdar Onses a postdoctoral scientist at Illinois. Onses earned his doctorate at the University of Wisconsin
or spatially placed over a wafer. his invention to use ink-jet printing to deposit different block copolymer films with high spatial resolution over the substrate is highly enabling in terms of device design
or different templates in different regions. he advanced form of ink-jet printing the engineers use to locally deposit block copolymers is called electrohydrodynamic or e-jet printing.
It operates much like the ink jet-printers printers office workers use for printing on paper. he idea is flow of materials from small openings except e-jet is a special high-resolution version of ink jet-printers printers that can print features down
and other types of nanomaterials. he most interesting aspect of this work is the ability to combine top down techniques of jet printing with â##bottom upâ##processes of self-assembly in a way that opens up new capabilities
