House-hold waste is a huge problem in the world, especially in developing countries where it is not properly disposed off, and causes serious health hazards and environmental concerns. Some of the waste materials like polyethylene products used for packaging pose even more serious ecological threats as they are not even biodegradable. In such a scenario, the efforts by scientists to formulate plans to make garbage a useful resource for fulfilling energy requirements by converting it into biofuel and into electricity by using the heat generated from it, definitely is a welcome step that will have far-reaching effects.

If the heat generated from the waste material could be converted to electricity, it will be immensely beneficial as it would drastically reduce load on other raw materials used for electricity generation and also do away with those materials that damage the ozone layer. Similarly, the processed food waste can be used to produce biofuels which can replace gasoline thereby reducing carbon emission. The scientific research and the latest developments in this direction have shown some promising results and have raised a hope for the permanent solution of this big menace.

World's Thinnest Light Bulb Created from Graphene
Graphene, a form of carbon famous for being stronger than steel and more conductive than copper, can add another wonder to the list, Light-Emitting Graphene. Researchers have developed a light-emitting graphene transistor that works in the same way as the filament in a light bulb.

Scientists have long wanted to create a teensy "light bulb" to place on a chip, enabling what is called photonic circuits, which run on light rather than electric current. The problem has been one of size and temperature–incandescent filaments must get extremely hot before they can produce visible light. This new graphene device, however, is so efficient and tiny that the resulting technology could offer new ways to make displays or study high-temperature phenomena at small scales.

In Graphene light, strips of graphene, which is a few microns across and from 6.5 to 14 microns in length, is used just as tungsten is used in incandescent light. An electrode is attached to the ends of each graphene strip, and the current is passed through graphene. This results in lighting up of the graphene.

Cracking Cocktail Party Problem
Assume that you are sitting in a crowded place and having conversation, but are not able to hear it properly. Or you might be interested in tapping a particular voice or conversation in a noisy place to foil an unlawful activity.

To solve such problems, what scientists call the cocktail party problem, the researchers have built a pizza pie-sized disk that is divided into 36 wedges and imprinted with centimeters-high hexagonal cells. The height of the cells varies in each wedge so that incoming sound waves would propagate differently, depending on their frequency. This disk records the incoming sounds, and then through a computer algorithm identifies what was said and by whom.

This device is made up of a 3D printed plastic disk which can help pick out a voice from a crowd, a task that is easy for people, but not for technology. The device could lead to improved voice recognition and hearing aids.

Revolutionizing Design Interaction and Collaboration
Hyve-3D is a new interface for 3D content creation via embodied and collaborative 3D sketching. The system is a full scale immersive 3D environment. In this system, users create drawings on hand-held tablets. They can then use the tablets to manipulate the sketches to create a 3D design within the space.

The 3D images are the result of an optical illusion created by a widescreen high-resolution projector, a specially designed 5m-diameter spherically concave fabric screen and a 16-inch dome mirror projecting the image onto the screen. The system is driven by a MacBook Pro laptop, a tracking system with two 3D sensors and two iPad mini tablets. Each iPad is attached to a tracker. The software takes care of all the networking, scene management, 3D graphics and projection, and also couples the sensors input and iPad devices. The iPads run a satellite application that serves as the front-end of the system for user interaction. Specialized techniques render the 3D scene onto a spherical projection in real-time. The Hyve-3D software also works on conventional 2D displays.
