#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

Using mouse studies only about 100 genes with imprinted expression had been identified. To determine whether other genes exhibit imprinted expression Wang
Of those genes transcriptome data from placental tissue revealed that 93 genes were imprinted. While only 15 of the 40 known imprinted human genes were identified in this set their expression bias was identical to that of humans indicating a highly conserved function for these genes between the horse family and humans.

#Convert microscope into billion-pixel imager for $200 CALTECH (US) Engineers have devised a way to convert a conventional microscope into a billion-pixel imaging system for about $200. n my view,
And building upon a conventional microscope, the new system costs only about $200 to implement. ne big advantage of this new approach is the hardware compatibility,
No other hardware modification is needed. The rest of the job is done by the computer. The new system acquires about 150 low-resolution images of a sample.
Each image corresponds to one LED element in the LED array. Therefore in the various images, light coming from known different directions illuminates the sample.
because the system acquires a complete set of data about the light field, it can computationally correct errorsuch as out of focus-focus imageso samples do need not to be rescanned. t will take the same data
and allow you to perform refocusing computationally, Yang says. The researchers say that the new method could have wide applications not only in digital pathology but also in everything from hematology to wafer inspection to forensic photography.

Manly explains that neutrinos are notoriously difficult to study and the oscillation that the researchers seek can be mimicked by other processes.
The researchers have gathered now 3. 5 times more data and this transformation is established firmly. The probability that random statistical fluctuations alone would produce the observed excess of electron neutrinos is less than one in a trillion.
An analysis of the data from the Super-Kamiokande detector associated with the neutrino beam time from J-PARC reveals that there are more electron neutrinos (a total of 28 events) than would be expected (4. 6 events) without this new process.
#iphone artists help solve#fat finger#problem CARNEGIE MELLON (US) Using the data amassed with an iphone drawing game,
researchers have built a tool that improves touchscreen art. The fingers of thousands of people who created sketches of Brad pitt
and Angelina jolie on their iphones can collectively guide and correct the drawing strokes of subsequent touchscreen users in an application created by researchers at Carnegie mellon University and Microsoft Research.
The app compensates for the at fingerproblem associated with touchscreens, automatically correcting a person drawing strokes
while preserving the user artistic style. ur goal was to make it invisible to the user, so people wouldn even be aware the correction is taking place,
says Alex Limpaecher, a Ph d. student in Carnegie mellon University computer science department. Adrien Treuille, associate professor of computer science and robotics, says the drawing assistance app is just one example of how Big data can be used to enhance drawing
and writing on touchscreens and even provide deep insights into art and perception. The trick has been to create drawing databases large enough to leveragen obstacle that he
and his research team surmounted with an iphone drawing game. The game they created, Drawafriend
motivated thousands of people to sketch Brad pitt, Angelina jolie, and other celebrities. In its first week, the game generated 1, 500 images a day.
The game is still operational and the resulting database now includes more than 17,000 images, each with stroke-by-stroke information about how it was created. e are in the middle of a Big data revolution,
Treuille says. ee found that Big data can be used to do amazing things. But success is not inevitable;
With Drawafriend, wee found a way to use crowdsourcing to create this critical resource for a data-impoverished phenomenon.
Real-time correction In Drawafriend, players take turns drawing faces of celebrities or of mutual friends from Facebook.
Not only does it create a large database of drawing strokes the game motivates players to try to draw as best they can
The team used the database of celebrity photos to create a simple stroke-correction method.
By determining the consensus of the strokes from the database drawings, they found that they could cancel out the oisecaused by large fingers trying to draw on small screens.
This correction occurs in real-time so the person is not aware that the drawing is being cleaned up even as it is being created.
For instance, Limpaecher says algorithms have previously been created for identifying whether a person is drawing a face,
but large databases have not been available to enable their use. Likewise, the correction function now used for sketches based on photos could be modified for freehand drawing.
To broaden the database the game could be modified to include drawings other than portrait sketches. Treuille says databases of drawings also could be used to address more basic questions.
Drawings often differ substantially in appearance from their real-life subjects, he notes, which suggests that databases of drawings could be mined for insights into human perception.
Such findings, in turn, might help in developing better object recognition or scene analysis for computer vision systems.
The databases also might be used to create teaching tools to improve the artistic techniques of students,
he adds. Limpaecher presented the findings at SIGGRAPH 2013 the International Conference on Computer graphics and Interactive Techniques, in Anaheim, California.
In addition to Treuille, the other team members were Nicholas Feltman, a Ph d. student in computer science, and Michael Cohen, principal researcher in Microsoft Research Interactive Visual Media Group.

when the wireless signal weakens. The new technology called streamloading could make spotty streaming and data-hogging downloads a thing of the past.
In the simplest terms streamloading makes use of a video format that splits the video into two layers#a base layer
Traditional streaming involves downloading 30 to 60 seconds of video ahead of time with the video quality and speed varying depending on wireless signal strength.
Streamloading allows users to pre-download the enhancement layer onto their devices in a location where wireless signal is strong#at home for example#and stream only the base layer at the time of viewing.
Shivendra S. Panwar professor of electrical and computer engineering the Polytechnic institute of New york University and the lead developer of streamloading estimates that the technique could remove as much as 75 percent of the streaming content from increasingly overloaded cellular wireless networks
while at the same time reducing high data usage charges for consumers Panwar explains that#in the best-case scenario we ll at the same time relieve some of the bandwidth crunch for wireless carriers
Although users will technically be downloading and saving content on their devices#something that s prohibited by streaming content services like Netflix#Panwar explains that

and with the data accumulated over that period we have a better scientific understanding of how fast the insects evolve resistance and why.#
#Analyzing data from 77 studies of 13 pest species in eight countries on five continents the researchers found well-documented cases of field-evolved resistance to Bt crops in five major pests
#Computer models showed that refuges should be especially good for delaying resistance when inheritance of resistance in the pest is recessive#explains Carri##re.
#If the data indicate that the pest s resistance is likely to be recessive and resistance is rare initially the risk of rapid resistance evolution is low#Tabashnik says.
Although the new report is the most comprehensive evaluation of pest resistance to Bt crops so far Tabashnik emphasizes that it represents only the beginning of using systematic data analyses to enhance understanding and management of resistance.#
The progress made provides motivation to collect more data and to incorporate it in planning future crop deployments.#

In fact research has found that transmission rates go up when hookup sites#even ones on the tamer end like Craigslist#come to town.
But smartphones are also capable of transforming into competitive diagnostic tools as a team of biomedical engineers out of Columbia University is showing with their new attachment that can detect both HIV and syphilis in a single 15-minute test.
The dongle as the team writes in the journal Science Translational Medicine costs just $34 to make (an amount that could drop further if mass produced.
It uses the phone#s power and data collection and incorporates simple optics and fluid control to process a finger prick of blood.

#Autodesk is now selling an open-source 3d printer Autodesk first foray into hardware is here: The Ember 3d printer is now available for anyone to order.
At $5, 995, the printer isn exactly a steal. Autodesk more so built it to be the perfect exhibitor for its open-source Spark 3d printing software,
which is currently in beta. People married to Autodesk suite of software might find that pairing of interest,
but the greater 3d printing industry might buy Ember because Autodesk plans to release exactly how it is built
and operates. Makerbot, the best known desktop 3d printer brand, gave rise to an entire class of printers
because its first machines were similarly open source. Ember could do the same for a different desktop technology.
I had the chance to see Ember in action at Autodesk Pier 9 manufacturing space in San francisco. It a digital light processing machine,

a necessary step in DLP printing. The Ember printer handles that last step in an unusual way.
The tank is shaped like a cashew; a half-instead of the square shape used by every other DLP printer.
After each layer is printed, the print platform raises slightly and the tank whips around the curve of the machine before returning to its home position.
Autodesk chose the unusual tank design because it requires the machine to use a lot less force, according to Autodesk 3d printing research scientist Andreas Bastian.
Each time the projector cures a layer, it creates a huge amount of suction between the 3d printed object and the bottom of the resin tank.

but my personal run-in with the printer at Pier 9 was welcome confirmation that Ember really exists,
