Grid-Inspecting Robots
Phillips, along with other researchers at the institute, has developed a 140-pound, six-foot-long prototype of a robot that will be able to slide along power lines for inspection. The robot can even maneuver past towers along the lines using cables that are either built on to or retrofitted to the tower. Using high definition cameras and sensors, the robot will be able to provide clear digital images to various inspection locations via satellite. The robot can detect a problem by recording an image at millions of points on the line. If the image is altered at the same exact point during the next inspection, a problem will be reported. This is highly important for reporting possible risks such as overgrown trees, which are the numer one cause of line breaks. The robot will move at about 3mph and make about two 80 mile trips during the span of one year. The solar panel design of the robot was originally constructed for the robot to run off the sun's energy. However, researchers found it more efficient to use solar energy as backup power, and have the robot run on the energy it absorbs from the wires through electromagnetic induction.
This new robot has sparked the interest of various power companies in America. For instance, George Juhn, director of investment planning and asset management at Ontario transmission giant Hydro One, stated that "[The new robot] would definitely be of interest to us." Field testing for the robot will begin in 2014.

Solar Fuel
Joule, using gene manipulation and design, has created photosynthetic mociroorganisms that use sunlight to convert carbon dioxide into ethanol or diesel. According to Joule, such organisms have never been created before. Their method is considered more effective than biomass approaches because Joule’s photobioreacters in which the microbes grow are significantly smaller and require no fresh water. Afeyan has also created a genetic switch for the microbes that will be used in order to limit their growth. This will allow for the energy of the process to be used toward fuel production rather than the organisms’ growth. According to Afeyan ,the process will yield 100 times as much fuel per hectare as fermenting corn to produce ethanol, and 10 times as much as making it from sources such as agricultural waste.
While the development seems immensely promising, Afeyan and other supporters are fully aware of possible setbacks and difficulties. For instance, the International Energy Agency estimates that by 2050, biofuels will only account for 26% of the world’s demand for transportation fuel. Also, Afeyan understands the huge financial risk of bringing biofuel production to a massive scale. However, he will carry out his plan on a smaller scale by running an outdoor pilot plant, which is currently under construction, in Leander, Texas. Afeyan sees a great promise in Joule’s current project and urges the company to stay innovative. Regarding his solar fuel development, Afeyan maintains, “We have the elements of a potentially transformative technology.”

Dual Action Antibodies
At the tip of each branch the antibody is an active site, which grabs a specific molecule on an invading microbe or cancer cell. Many of the antibodies have the ability to weakly bind to a second antigen. By exploiting this ability and making the bonds tight and functional Fuh’s team was able to create a dual action antibody that was somewhat successful. Their experiments t have fueled interest in the overall potential of such drugs and their effects can be phenomenal. If the concept proves successful, antibodies that stick to two targets might be used to treat infectious diseases as well as cancer--offering the promise of drugs that work better and cost less.

The Future for Fusion
Today, when chemistry classes teach nuclear chemistry, students learn that fusion reactions release more energy than fission reactions, are inexpensive, and produce non-radioactive products. Yet, fission reactions which hold environmental concern, such as where to dispose its radioactive waste, are currently used. The major setback with fusion is the high temperatures needed which cannot be contained.
However, emerging technology has not only begun the creation of fusion reactors but is now trying to build a new fusion reactor that can achieve ignition, “the point where a fusion reaction becomes self-sustaining instead of requiring a constant input of energy.”MIT physics professor, Bruno Coppi, is the principal investigator for Ignitor; a tokamak reactor.
This new reactor uses “powerful magnetic fields to produce fusion by squeezing superheated plasma of hydrogen isotopes”. The plasma is heated to extreme temperatures when an electric current and high-frequency radio waves pass through the plasma. However, the heat is confined by electromagnetic fields through high pressure. Both the pressure and the heat will than cause hydrogen nuclei to fuse and form helium. This process is what will release the enormous amount of heat that will then be used to power an electricity-generating turbine.
Unlike the International Thermonuclear Experimental Reactor (ITER), a reactor being built in

Green Concrete
Walk up to a friend and ask them what the effects the production of concrete has on the environment. Most people would probably not be aware. However, now is the time to educate ourselves. The fact is that in 2009, the production of concrete contributed to five percent of all carbon dioxide emissions. As the effects of pollution and human population continue to take a toll in our world, it is vital to recognize and encourage emerging green technologies.
Nikolaos Vlasopoulos of Novacem, discovered a way to create concrete without its harmful effects. While working as a grad student in
First, the green concrete actually absorbs carbon dioxide. Although it does produce carbon dioxide, it absorbs more than it created during setting. In comparison of Portland cement which creates 700kg per tone of carbon dioxide and absorbs 100-500kg per tone, the green concrete creates 200-400kg per tone of carbon dioxide and absorbs about 2.5 times more than Portland cement.
Another benefit of this new technology is that it is possible to be recycled if a building is torn down. It can be mixed with waste material such as glass or plastic. Portland cement cannot do this. Lastly, Novacem will use the same processes as Portland cement. This means that construction firms will not need to change the way they operate, thereby making a transition to green concrete much smoother.
Unfortunately, the green concrete is not in the market. Vlasopoulos states he should be done refining the product “within a year”. Some problems that this green cement is facing is the necessity to produce in industrial levels and match the price of other cements like

Implantable Electronics
Today's implantable devices must be surgically replaced or removed at some point, so its only worth using an implant for important devices such as pacemakers. Silk is biodegradable and soft, can carry light like optical glass or made into transistor or wire. this means that silk can sit right on top of tissues without irritation for years or just a instance.Soon we may have are health charts in our arm or legs. and our doctors can montior our health wireless and our own bodies tells us of a problems well bofore it happens.

Gold Nanosensors
Gold Nanosensors can now be implanted into the body to continuously monitor for blood clots. Gold Nanosensors are injected directly into the patient, allowing the doctor to measure protein concentrations by shining a laser light through the skin. This new technology will allow scientists to directly examine proteins and how they interact within a cell. Some of these proteins include ones that are involved in viral infections. 120 nanometers in diameter, the sensor consists of a silica core, encapsulated in a thin layer of gold. On top of the gold shell, are aptamers, or short strands of nucleic acids to bind to a specific molecule. When shining a laser on the aptamer, the molecule absorbs the light and will emit a characteristic spectrum allowing the doctor to view many different things. This new technology is not only cheap but it would provide easy monitoring for high-risk individuals and prevent clot-related deaths. Currently, research is being done at the

IKAROS: The First Step to Interplanetary Travel
In layman's terms, solar-powered spacecrafts use the energy of the sun in order to propel through space. This eliminates the need of an engine. These spacecrafts only require three things: a continuous force exerted by the sun, an enormous, ultra thin mirror, and a separate launch vehicle. The electromagnetic radiation contained within light exerts a force on the sails. The photons given off by the sun reflect off of the giant mirror. In the vacuum of space, even a small collision will cause something to move. The bigger the mirror, the more collisions and the faster the spacecraft moves. This method causes the spacecraft to move about 5x faster than a traditional one, all while using significantly less energy.
The next step in solar sail travel is contained in the IKAROS project. The IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun), will use a Solar "Power" Sail. The difference between this and a solar sail is that the "power" sail collects electricity in the solar cells of its membrane. But, like the solar sail, it still gets accelerated by the radiation of the sun. The advantage of the "power" sail is that it creates (to a certain extent) a "hybrid" engine. Space missions with such sails will be much more flexible as the engine can rely on both photon acceleration and ion-propulsion engines driven by solar cells. Hopefully, scientists believe, the continuation of research on solar "power" sails will yield much longer space travel missions that would ultimately result in interplanetary travel.
The IKAROS will launch later in 2010 in order to test the effectiveness of the sails. The shape of the membrane is square, with a diagonal distance of 20m. It is made of polyimide a mere 0.0075mm thick. In addition to the thin film solar cells, the steering devices and dust-counter sensors are fitted to the membrane. The sail will rotate at 20rpm for several weeks in space in order to generate solar power with a minimum success level. Within a year, sail navigation and acceleration will occur at full success level.

New Possibilities with Optogenetics
The new off switch is twenty times more responsive than yellow light used in previous generations. Also, the future looks prosperous since red and near-infrared light in known to be able to penetrate deeper into tissue. In one study, Jerry Silver used optogenetics to explore bladder control after spinal cord injuries. He turned off the nerves located in the lower spine that relax the bladder. However, he has noted how, in the past, the use of so much light creates too much heat. The new tools, he believes, seem to need less light which would produce less heat while being able to invade farther into the tissue. He is extremely hopeful of the future.
Another application of optogenetics is being led by Richard H. Kramer who believes that restoration of sight can be achieved through the use of labels. Kramers technique is different because he uses photosensitive compounds which will attach to cells through chemical means rather than using genetic engineering. He and his colleagues focus on potassium channels and manipulate the activation or inhibition of neurons through these channels. Next, “to attach the label, the researchers simply bathe cells in a solution containing the molecule.” A molecule called azobenzene, a photoisomer, changes its physical but not chemical composition when exposed to light. The label will actually allow the neuron to be illuminated continuously. This connects with Kramer’s goal to restore sight because he says, “The long-term hope is that something like the compounds we've developed might be able to restore sight using cells that aren't normally light sensitive." Therefore, although cones or retina’s rods may have been damaged, other nerve cells can be made to pick up photons which normally do not. However, this is still in the early stages and the side effects of such actions have yet to be observed in animals. Regardless, the new field and technology of optogenetics seems promising and capable of benefiting a broad range of problems from depression and Parkinson’s disease to the loss of sight.

NASA’s Mars Rover
The software update on the Mars Rovers, called Autonomous Exploration for Gathering Increased Science(AEGIS), allows the rovers to make their own choices. This means that instead of transmitting the post-drive navigation camera images to earth first and then waiting for ground operators to check for points of interest and being able to examine them another day, the rovers can detect their own targets and examine them themselves, while sending pictures down to earth for scientists to examine. The new system gives the rovers the ability to examine images, and identify them based on shape, or color. In addition, these rovers can now figure out how to get around objects and to calculate the distance between its’ arm and a rock, so it can pick it up. Autonomous Exploration for Gathering Increased Science(AEGIS) lets scientists highlight types of places that could be of interest to the rovers’, for example dark places. This new software update will better help scientists hoping to know more about the planet Mars.

The Future of Urban Mobility
The two-wheeled concept, known as the Electric Networked-Vehicle (EN-V) concept, involves many unprecedented vehicle technologies. In each of the two wheels, there is an electric powered motor. The motors not only provide power for acceleration, but also bring the vehicle to a stop. GM has also worked aside Segway in order to create a drivetrain platform and an efficient energy source for the car. The platform for the car is an evolution of the platform Segway developed for the Personal Urban Mobility and Accessibility (P.U.M.A.) prototype. The companies have worked together to develop and deliver multiple copies of the platform that can connect to multiple EN-V’s.
The EN-V cars are powered with lithium ion batteries and can be charged in standard wall outlets. The car is able to communicate with the electric grid in order to determine optimum charge times. One charge can power the car for over a 40km distance.
GM has combined GPS, vehicle-to-vehicle communication, and distance sensing technology in order to develop an autonomous driving option. Vehicle based sensor and camera systems enable the EN-V to decelerate and stop before reaching an unexpected pedestrian. Also, these systems allow the car to maneuver through traffic and perform other difficult driving tasks such as merging, passing, and parking. Alan Taub, Global VP of GM Research and Development, claims, "The EN-V concept represents a major breakthrough in the research that GM has been doing to bring vehicle autonomy to life."

n.Fluent ( Intergrated web based translation)
Language-- the only thing separating us from other cultures and way of life around the world. Now imagine if there was a way to view any webpage in your fluent language. Combining these two ideas, IMB has created a webpage interface to do such a thing(through machine based translation). The n.Fluent from IBM automatically translates the webpage of your choice to your preferred language. Although this idea is still in developmental stage, it has been idea since 2006 and is growing ever near to being released. This very idea was started because IBM realized language was a key issue for business transactions and companies with online clients around the world.
Google is also working on creating a web based tool to translate not just web pages but search engines in general – seeing how the Google search engine only recognizes English words. One downside to this is all the work that has to be put into translating words in every language available – which is where crowd sourcing comes in. crowd sourcing English words to volunteers effectively cuts down the time it takes for one company to translate all the words themselves. Using this method, in a years time 30,000 crowd sourcing volunteers translated 36 millions words (and the volunteers are still pouring in).

3-D Television
blocking one eye at a time so that each eye sees only the frame meant for it. Each one of our eyes have different perspectives of the same scene we are looking at. The brain takes both images, and fuses them together, helping us to have a sense of depth. Getting the 3-D effect at home involves tricking the brain into doing something similar, however with the images you get from a TV set. TV makers have to figure out a way to precisely show a set of slightly differnt images to each of your eyes. Many times, as used in movie theaters, people have to wear Glasses which enhance the picture, resulting in a 3 dimensional image. However, LG's 3D TV does not require glasses. This TV uses lenticules, a cylindrical plastic that goes on the LCD screen, which magnify and enlarge the display on the screen. When the viewers are sitting in the right angle, the brain combines the two views from each of your eyes, and creates the perception of depth, the 3D image. This technology is not essential, however, it is essential for entertainment. Films such as Avatar, shown in 3D, made more money than movies shown in regular 2D. You can expect to see projects in stores in 2010.

Silicon computer chips successfully implanted in living human cells
Once the chips were implanted thet monitored the cells to make sure they were living and healthy. The scientists discovered that the implanted cells stayed alive and working for a week, 90% of the cells remained and only a very small amount died. The most important goal for the scientists was to create intracellular sensors and make sure they worked perfectly and can be used in humans to possibly cure diseases." "Today's micro- and nanoelectronic processes already would allow us to produce complex 3-dimensional microscale structures as sensors and actuators," said Plaza. The main applications of future intracellular chips will be the study of individual cells. This technology could aid in the early detection of diseases and new cellular repair mechanisms.

Wireless Controlled from the Cloud
RNA – Loaded Nanoparticles
A major problem with the application of the technology is how to get the therapeutic RNA into the cell. “When injected on their own, so-called small interfering RNAs (siRNAs) are quickly filtered out by the kidneys, and researchers have struggled to design particles that carry their contents to target cells with enough specificity, or that don't cause toxicity or elicit an immune reaction from the body.” Nevertheless, Mark Davis, the Warren and Katharine Schlinger Professor of Chemical Engineering at Caltech, and the research team’s leader, has already been studying ways in which deliver nucleic acids into cells. Davis and his team have created a “four-component system – featuring a unique polymer – that can self-assemble into a targeted siRNA-containing nanoparticle. Once the nanoparticle reaches its destination, the cancerous cell can then releases the siRNAs.
Using the new technique with the RNAi technology, the team was able to analyze tissue from trial participants. There have been several different studies and trails, all in experimental and early stages using RNAi. The three melanoma patients in the trail at Caltech have been given different dosages. A direct relationship between the amounts of particles in the tumor and the dosages was discovered; “That's the first time anyone has seen that for any kind of particle delivery system, whether it's a liposome, a nanoparticle, or anything," said David. Another exciting finding was that the mRNAs were cut in the exact same way the siRNAs were intended to cut. A different trail, funded by the Department of Science and Technology of Zhejiang Province and by City of Hope National Medical Center and Beckman Research Institute, was used in breast cancer patients. “The study demonstrated the potential of inhibiting telomerase[using siRNAs] as an effective treatment of breast cancer when used alone and, when used in conjunction to doxorubicin [most common drug used for breast cancer treatment], could potentiate the cytotoxic effect of the drug to breast cancer cells.”
The side affects of the patients have yet to be revealed, and although the scale of the trails are small, there is much hope for this new technology to allow more effective cancer treatments. ‘"At the very least, we've proven that the RNAi mechanism can be used in humans for therapy and that the targeted delivery of siRNA allows for systemic administration," Davis says. "It is a very exciting time."

A Newer, Faster External Hard Drive

A Revolution In PC Gaming
Quantum computing
Quantum computing is the control and observation of quantum particles. Researchers have newly discovered two different ways to place an electron in a nano-sized device on a silicon chip. A quantum computer processor is made up of several quantum bits bundled together. An artificial atom or a quantum dot is a localized single electron that is not attached to an atom. The quantum dot made it easier to introduce the single atom in a silicon disk.
The quantum computer’s power is generated by the electrons spin. The spin can point in one of two directions, imitating the one’s and zero’s in today’s computer system. Electrons also have the ability to stay in a specific spin position, allowing energy to be created, by the electrons.
This break through is the basis of more complex things to come. For example, researchers are working on trying to control the electron’s quantum state for observational reasons.

Silicon Microwires Could Have a Sunny Future
http://www.technologyreview.
The attractions of solar power's enormous benefits have led
scientists to race to find a way to create inexpensive, optimally efficient
way solar cells. This venture has been broadly and avidly taken on for many
years by numerous scientists, who have come up with different ways of
creating solar cells. But, none of them are really cost-effective or
sufficiently usable. Recently, it has been found that silicon microwires may
be the solution. Efforts to develop ultra-thin wires that convert sunlight
into electricity have been happening for quite a while in the solar power
research field, but a new method for growing the wires involving silicon
microwires, has roughly doubled their conversion efficiency and may be the
key to advancing further. "All wires thus far have had 1 or 2 percent
efficiency [at the array level] with fundamental questions about whether
they could ever go higher," says Nathan Lewis, a chemist at Caltech who coauthored the study, which appears in *Science.*" It is possible that it can go all the way up to 10% efficiency
an inexpensive method.
Silicon nanowires are usually grown from a silicon substrate with the help
of tiny gold droplets. Under high temperatures, a single wire will quickly
sprout from each droplet like a blade of grass. Gold is an excellent
catalyst for wire growth, but it also introduces impurities that are
generally believed to inhibit electron transport within the wires, reducing
their overall efficiency. By using copper as a better, cheaper alternative,
efficiency rates nearly doubled from the previous wires that came from the
gold, because of higher silicon purity and increased electron transport
capacity. With the development of this new technology, we could be well on
our way to establishing solar power panels throughout the world, at a much
more reasonable price and an excellent usability with innumerous benefits.
