This could help unlock successful treatments for common neurological conditions such as Alzheimer’s and Parkinson’s. Project leader Dr Sharath Sriram, co-leader of RMIT Functional Materials and Microsystems Research Group, has said that the ground-breaking development imitates the way the brain uses long-term memory.<br /> The research builds on RMIT’s previous discovery where ultra-fast nano-scale memories were developed using a functional oxide material in the form of an ultrathin film, which is 10,000 times thinner than a human hair.

It<br />involves surgically implanting myoelectric sensors<br />(IMES) into a person’s residual muscle tissue to<br />measure and interpret signals travelling between the<br />brain and its nerve-endings. The implanted sensors send<br />wireless signals to the artificial limb’s built-in computer,<br />enabling subconscious, real-time control and faster,<br />more natural responses and movements.<br />This new mindcontrolled technology developed by Ossur for<br />lower-limb prosthetics is designed to be compatible with its line of bionic feet, knees and legs. A coiled-wire receiver inside the<br />prosthesis’ cup picks up impulses and transmits these<br />wirelessly to the robotic limb.<br /> <br /> <h3>  </h3> <h3> A computer made out of water droplets</h3> An assistant professor of bioengineering at Stanford University, the USA, Prof. Manu Prakash has created a water based computer. He, along with his two students, has devised a system with the help of tiny water droplets that could work as a computer clock. For this, water droplets are trapped in a magnetic field. When applied to a flipped magnetic field, these form a precise motion in a fixed direction. According to the team, the system can be made smaller by controlling millions of droplets with the help of the magnetic field, so that it can perform a higher number of operations on a single chip. According to Prakash, this computer founds its application in biology and chemistry by converting the computer into a high-throughput laboratory.

The implants were made using a 3D printer, which can create items from a wide variety of materials such as plastic, ceramic,</h4> <div style="text-align: justify;"> glass, metal and even living cells.<br /> Scientists have now begun developing techniques to try out 4D printing, which involves 3D printing items that are designed to shape-shift after being printed. The three infant boys who were implanted with the new device were suffering from tracheobronchomalacia, a disease that causes the windpipe to regularly collapse, preventing normal breathing. Researchers used CT scans of the boys to develop 3D-printed airway splints whose</div> <div style="text-align: justify;"> length, diameter, thickness and other factors were customised for each baby. The splints, made of polycaprolactone that dissolves in the body over time, were implanted into the babies and sewn around their windpipes; devices kept surrounding tissue from pushing in and sealing the airways shut. These hollow and porous splints were designed to spread open as the children grew.</div> <h3 style="text-align: justify;">  </h3> <h3 style="text-align: justify;"> Hyperlens that helps view tiny objects</h3> <div style="text-align: justify;"> According to scientists, a slinky hyperlens can help us see tiny objects that elude even the most powerful optical systems. The metamaterial hyperlens may someday even help detect some of the most lethal forms of cancer. It is also expected to lead to advancements in nano-electronic manufacturing and boost a scientist’s ability to examine single molecules. Conventional optical systems, such as microscopes and cameras, are limited by diffraction, a phenomena in which light bends as it passes around an edge or through a slit. Metamaterial hyperlenses overcome the diffraction limit by transforming decaying evanescent waves into propagating waves. Once converted, the former decaying waves, which were commonly lost in conventional imaging, can be collected and transmitted using standard optical components.</div> <h3 style="text-align: justify;">  </h3> <h3 style="text-align: justify;"> Lift your house in case of an earthquake</h3> <div style="text-align: justify;"> The future vision for Greg Henderson of Arx Pax, makers of Hendo Hoverboard, is deploying the<br /> technology Hendo Hoverboard uses on a large-scale to protect houses during a massive earthquake.<br /> Arx Pax has in place systems that employ water or gas to lift homes. It, however, aims to eliminate the structural movement entirely and use magnets instead. Their goal is to have the building’s landing gear react and activate the hover engines as soon as an earthquake strikes. In order to lift a three-story home for about 90 seconds, which is the length of an average earthquake, the power required can be supplied using five car batteries.</div> <div style="text-align: justify;"> Arx Pax would require installation of the hover engines and an earthquake-proof base. Computers would automatically turn on the engines as soon as these sense an earthquake. These will also have ShakingAlert software system that senses earthquakes, integrated in the system, which has successfully detected earthquakes in the past.</div>

A section of the robotic arm is built to handle soft organs without damaging these, while another section operates on the patient.<br /> This technique could minimise the number of instruments needed for surgical procedures, which<br /> means that doctors would need to make fewer entry incisions on patients, lessening the chance of<br /> postoperative complications. This robotic arm, which is made of soft material, is capable of carrying out multiple tasks during an operation, unlike other flexible surgical robotics.<br /> <h3>  </h3> <h3> Robots can now think like humans</h3>  Based on new algorithms developed by researchers from University of California, Berkeley, the USA, robots can now learn from their mistakes just like humans do. Researchers were able to level up artificial intelligence (AI) by making the robots learn motor tasks using trial and error.<br /> The robot named BRETT stands for Berkeley Robot of the Elimination of Tedious Tasks. Using the technique developed by reaserchers, the robot learns to recognise patterns and categorise data that it receives using deep learning programs that can create neural nets in which overlapping raw sensory data (sound wave or image pixels) can be processed by layers of artificial neurons.<br /> Since the robot does not have any pre-programmed knowledge on its environment, it can successfully assemble basic objects after several attempts. BRETT’s first task that was to assemble a toy airplane<br /> wheel took 12 minutes before completion. Eventually, it applied the same algorithm that it learned from the toy airplane to its second task on Lego bricks and finished the task almost right away.<br /> <h3>  </h3> <h3> Technology to put electronics into the brain</h3> Latest technologies have allowed a paralysed man to drink from a cup unaided using a robotic arm, the deaf to hear and the blind to see, using brain implants that are electrical devices inserted into or attached to the brain. At present, implants require invasive surgery and are often made of metals that may cause scarring. Brain implant technology is hampered by how long implants can stay in the brain without losing functionality.<br /> Now, a tiny new brain implant makes a breakthrough in this area. It can be injected directly into the brain using a syringe, minimising damage to brain tissue. The flexible mesh mimics the interconnecting structure of the neural network and the softness of brain tissue. It is made of materials that the immune system is less likely to reject, resulting in less scarring in the brain.<br /> The implant contains very fine metal lines of circuitry embedded on it, with electrodes and sensors mounted at intersections of wires. After being injected into the brain, it unfolds to about 80 per cent of its original shape without losing function. External wires of the mesh can then be plugged to a computer to monitor and stimulate individual neurons.<br /> <h4> </h4> <br />
