The diseases macular degeneration and retinitis pigmentosa lay waste to photoreceptors, the cells in the electrical signals carried to the brain. The damage leaves millions of people worldwide with sight loss. The nerves behind the light –switching cells, however, remain intact, meaning that with new photoreceptors, a patient could see again.
Early attempts to regenerate sight by injecting seed or progenitor cells that grow into photoreceptors into the eye of a mouse model failed. Now, researchers trying to restore vision damaged by disease have found promise in a tiny implant that sows seeds of new cells in the eye, according to a Case Western Reserve University press release. As with any part of the central nervous system, scar tissue is a barrier to regeneration.
Published work has shown that people who suffer sight loss can again regain visual acuity with the addition of fewer photoreceptor cells than the number of cells that naturally populate a healthy eye. The researchers made the micro-implant’s scaffolding. They built a mesh using electrical charges to draw biodegradable polymers out of a needle and into a fine stream, producing interwoven fibres ranging from 1/20th to 1/1000th the width of a hair. Embedded in the fibres are pockets containing enzymes which slowly migrate out as the polymer degrades, eating away local scar tissue and exposing fertile ground for the progenitor cells carried on the implant’s surface. Without the enzymes, the implant alone increased the number of progenitor cells reaching the degraded site 16-fold and survival 9-fold over injection in a mouse model. With the enzymes, the number of progenitor cells that implanted and survived increased another 15-20 fold.

People tend to eat when they are stressed. The most direct route is the food-in-mouth syndrome: Stressful circumstances spark cravings for carbohydrate rich snacks, which in turn calm stress hormones. Stress hormones also ramp up fat storage. For our prehistoric ancestors, stress meant drought or approaching tigers, and a rapid storage process made sense; we needed the extra energy to survive food shortages or fight a battle. Today we take our stress sitting down-and the unused calories accumulate in our midsection. This accumulated fat cannot be removed by diet or exercise, weight loss surgery Cincinnati , is the only way to solve the problem. The surgery helps in removing the excess fat from the body and the body regains the shape. To whittle yourself to keep up the shape, in addition to the usual workout, make time for stress relief- whether it is yoga class or quality time with family.
Supplement tiny portions of high-calorie food with a tub of salad, fresh fruits and whole grains. Certain good fats from olives, avocados, and nuts are acceptable. Even red meat has its place in the spectrum. Avoid junk food and load up on colourful, antioxidant-rich fruits and vegetables.

Children fancy the Spiderman walking up the walls. Spiderman is the hero of millions of people, even adults. Technological advances have a way of catching up with our childhood fantasies, sooner or later. A palm-sized device invented by Cornell University researchers that uses water surface tension as an adhesive bond, just might make such a dizzying feat possible. The rapid adhesion mechanism could lead to such applications as shoes or gloves that stick and unstuck to walls, or Post-it-like notes that can bear loads, says Paul Steen, who invented it.
The device is the result of inspiration drawn from a beetle native to Florida, which can adhere to a leaf with a force 100 times its own weight, yet also instantly detach itself. The device consists of a flat plate patterned with holes, each a millionth of a metre. A bottom plate holds a liquid reservoir, and in the middle is another porous layer. An electric field applied by a common nine-volt battery pumps water through the device and causes droplets to squeeze through the top layer.
The surface tension of the exposed droplets makes the device grip another surface-much the way two wet glass slides stick together. They found that as they scaled down the holes and packed more of them onto the device, the adhesion got stronger. To turn the adhesion off, the electric field is simply reversed, and the water is pulled back through the pores.

Furniture plays a main role in the decoration of a room. If you are going to furnish your house, whether it is a new house or an old one, it is better to go in for modern furniture.

A collaboration between an F-16 pilot and a skateboard designer, the ICON A5 is a sport plane designed with retractable landing gear for flying off both land and water, and folding wings that allow the plane to be easily stored and towed on a trailer.
The light sport aircraft is 6.7m in length, 2.2m in height and the maximum weight is 650kg. The maximum speed of the plane is 190km/hr and it flies up to a range of 550km. The maximum altitude it can fly is 3,000m. The foldable wings can be manually folded in 10 minutes, or can be folded with automatic option in less than 60 seconds. Optional fitted parachute can lower plane to ground in case of emergency.
The airframe is made of light weight carbon fibre. A Rotax 912 ULS 100hp light sport aircraft engine drives the 3-bladed propeller. The wrap-around bubble canopy allows panoramic views. The cockpit seats two people and the plane can carry 27kg of luggage. The side windows are removable and the seawing ensures easy access and docking on water. The landing and takeoff can be both on land and water in less than 230m. It has a GPS screen that helps in finding the location of the craft relative to terrain, roads, airspace and weather.

Capturing only caesium from vast amounts of liquid nuclear waste is like looking for a needle in a haystack. The waste had a much higher concentration of sodium compared to caesium, with ratios as great as 1,000-to-1. This difficult to achieve selectivity is why currently there is no good solution for caesium removal.
Not every object is food to a Venus flytrap. Like the carnivorous plant, a new material developed at Northwestern University permanently traps only its desired prey, the radioactive ion caesium, and not other harmless ions like sodium. It is in fact, caesium itself that triggers a structural change in the material, causing it to snap shut its pores, or windows, and trap, the caesium ions within. The synthetic material, made from layers of gallium, sulphur and antimony compound, is very selective. It is extremely successful in removing caesium found in nuclear waste but very difficult to clean up from a sodium-heavy solution.
A new class of materials that takes advantage of the flytrap mechanism could lead to a much needed breakthrough in nuclear waste remediation. The snap-shut Venus flytrap mechanism occurs because soft materials like to interact with each other. A caesium ion is big and soft, and the metal sulphide material is soft, too. The caesium ions are attracted to the material, specifically the sulphur atoms, and together form a weak bond. This interaction causes the material to change shape, close its windows and trap the caesium. Sodium, which is clothed in water molecules, can’t trigger the response.
