The goal of the startup company known as HCEC LLC (Human Cultured Endothelial Cells) is to advance the technology to the next level
The current surgical technique is to replace a patient's damaged CECS with a very thin layer of tissue containing cells from a cadaveric donor cornea.
The goal of the new partnership is use regenerative medicine technology to meet this increased demand.
The technique of bioengineering replacement tissues using cells and scaffolds can theoretically be applied to almost any tissue in the body said Anthony Atala M d. director of the Wake Forest Institute for Regenerative Medicine.
but also lower-emitting nuclear and renewable energy technologies such as wind and solar. Inexpensive natural gas would also accelerate economic growth
Global deployment of advanced natural gas production technology could double or triple the global natural gas production by 2050
Thinking Globallyrecent advances in gas production technology based on horizontal drilling and hydraulic fracturing--also known as fracking--have led to bountiful low-cost natural gas.
But could these advanced technologies also have an impact on emissions beyond North america and decades into the future?
To find out a group of scientists engineers and policy experts led by PNNL's Joint Global Change Research Institute gathered at a workshop in Cambridge Maryland in April 2013 to consider the long-term impact of an expansion of the current natural gas boom on the rest of the world.

and Penn State university have developed an automated imaging technique for measuring and analyzing the root systems of mature plants.
The technique believed to be the first of its kind uses advanced computer technology to analyze photographs taken of root systems in the field.
We've produced an imaging system to evaluate the root systems of plants in field conditions said Alexander Bucksch a postdoctoral fellow in the Georgia Tech School of Biology and School of Interactive Computing.
and Basic Research to Enable Agriculture Development (BREAD) the Howard Buffett Foundation the Burroughs Wellcome Fund and the Center for Data analytics at Georgia Tech.
Beyond improving food crops the technique could also help improve plants grown for energy production materials and other purposes.
The technique developed by Georgia Tech and Penn State researchers uses digital photography to provide a detailed image of roots from mature plants in the field.
In the lab you are just seeing part of the process of root growth said Bucksch who works in the group of Associate professor Joshua Weitz in the School of Biology and School of Physics at Georgia Tech.
Developing the digital photography technique required iterative refinements to produce consistent images that could be analyzed using computer programs.
The research shows how quantitative measurement techniques from one discipline can be applied to other areas of science.
Data generated by the new technique will be used in subsequent analyses to help understand how changes in genetics affect plant growth.
This imaging technique provides data needed to accomplish this. Story Source: The above story is provided based on materials by Georgia Institute of technology.

The holy grail of wireless communications is to go both fast and far said lead researcher Edward Knightly professor and chair of Rice's Department of Electrical and Computer Engineering.
This provides the best of both worlds he said of the new technology. Rice's technology combines several proven technologies that are used already widely in wireless data transmission.
One of these is multiple-input multiple-output (MIMO) a scheme that employs multiple antennae to boost data rates without the need for additional channels or transmitter power.
and the technology is standard in the latest generation of wireless routers and networking equipment.
One way to do that is with multiuser MIMO a multiantenna transmission technique that serves multiple users over the same channel simultaneously.

improves manufacturabilityrice University's breakthrough silicon oxide technology for high-density next-generation computer memory is one step closer to mass production thanks to a refinement that will allow manufacturers to fabricate devices at room temperature with conventional
First discovered five years ago Rice's silicon oxide memories are a type of two-terminal resistive random-access memory (RRAM) technology.
In a new paper available online in the American Chemical Society journal Nano Letters a Rice team led by chemist James Tour compared its RRAM technology to more than a dozen competing versions.
Tour is Rice's T. T. and W. F. Chao Chair in Chemistry and professor of mechanical engineering and nanoengineering and of computer science.
Tour and colleagues began work on their breakthrough RRAM technology more than five years ago. The basic concept behind resistive memory devices is the insertion of a dielectric material--one that won't normally conduct electricity--between two wires.
RRAM is under development worldwide and expected to supplant flash memory technology in the marketplace within a few years
For example manufacturers have announced plans for RRAM prototype chips that will be capable of storing about one terabyte of data on a device the size of a postage stamp--more than 50 times the data density of current flash memory technology.
Microelectronics fabrication technologies based on silicon are widespread and easily understood but until the 2010 discovery of conductive filament pathways in silicon oxide in Tour's lab the material wasn't considered an option for RRAM.
At the same time the researchers also conducted countless tests to compare the performance of silicon oxide memories with competing dielectric RRAM technologies.
Our technology is the only one that satisfies every market requirement both from a production
First the porous material reduced the forming voltage--the power needed to form conduction pathways--to less than two volts a 13-fold improvement over the team's previous best and a number that stacks up against competing RRAM technologies.
and we've already been approached by companies interested in licensing this new technology he said.

and enable the economic production of gas resources with higher carbon dioxide content that would be too costly to recover using current carbon capture technologies Tour said.
The Tour lab with assistance from the National Institute of Standards and Technology (NIST) produced the patented material that pulls only carbon dioxide molecules from flowing natural gas
All of this works in ambient temperatures unlike current high-temperature capture technologies that use up a significant portion of the energy being produced.
Our technique allows one to specifically remove carbon dioxide at the source. It doesn't have to be transported to a collection station to do the separation he said.
and licensed the technology. Tour expected it will take time and more work on manufacturing and engineering aspects to commercialize.
Tour is the T. T. and W. F. Chao Chair in Chemistry as well as a professor of mechanical engineering and nanoengineering and of computer science.
Working under the auspices of the National Science Foundation the team spent two years evaluating more than 100 studies that addressed the various implications of climate engineering and their anticipated effects on greenhouse gases.
Technology that is already available could reduce the amount of carbon being added to the atmosphere by some 7 gigatons per year the team found.
We have the technology and we know how to do it Cusack said. It's just that there doesn't seem to be political support for reducing emissions.
The study's second most promising climate engineering strategy after carbon sequestration was carbon capture and storage particularly when the technique is used near where fuels are being refined.

Among the technologies evaluated in situ are floor type in cattle housing use of additives in slurry storage manure turning flexible lagoons for collective slurry storage biowashers for gases at the outlet of air ducts of the sheds
In this respect the members of the BATFARM project have developed software (BATFARM) to select the best farm waste technologies
Finally it should be pointed out that there is no single technology or practice to be recommended but that these need to be studied for each case;
The Directive proposes adopting Best Available Techniques (BAT) which means farmers must choose and apply those technologies available on the market
and which are economically affordable in farming the ultimate aim being to prevent or limit emissions.

The Cedars-Sinai surgeons highlight the advantages of a spinal navigation technique that uses high-speed computerized tomography (CT) imaging to navigate in and around the spinal column from different angles.
Computer-guided surgical navigation technology delivers on quality and safety said J. Patrick Johnson MD a neurosurgery spine specialist and director of Spine Education and the Neurosurgery Spine Fellowship program in the Department of Neurosurgery.
Surgeons said the technique is superior to existing methods because of its precision and speed. They point out that even small miscalculations with two-dimensional technology can cause problems that require follow-up operations
because hardware was initially out of place. The Cedars-Sinai surgeons say they have cut these to nearly zero by using computer-guided methods.
