According to U.S. media reports, recently, U.S. scientists have invented a brain signals in real-time translation technologies, into the brain of the device to wirelessly transmit brain signals from outside, the external speech synthesizer in real time the brain signals and to receive translated into words. Currently, the technology-based "brain machine interface" has been closed in SARS patients achieved a successful experiment.
According to scientists, the use of this technology, "thinking change language" of the process requires only 50 milliseconds, the amount of time just normal people with the nerve to express their thoughts in words when the same reaction time. The first successful results of this study show that in the human brain into wireless devices, by awareness of the outside of the brain in real-time control of audio devices. For those who because of nerve damage and loss of control of the people, the results will be their gospel.
The study was conducted by scientists at Boston University Frank - Guenteer led the implementation, Boston University, Department of perception and the nervous system, health and rehabilitation Sciences, Harvard - MIT Division of Health Sciences and Technology scientists to participate in this study. The study will be published in the United States, "PLoS" magazine.
Guenteer said, "Our research shows that 'brain machine interface', the language the user can directly control the output, than the use of relatively slow process of typing is much better."

British has created the energy-efficient "light-emitting wallpaper"
The Carbon Trust has announced that it will invest several hundred thousand pounds a company-funded R & D "light-emitting wallpaper", which is expected to result in the lighting and energy efficiency will be better than existing bulbs.
Carbon Trust announced the investment of 454,000 pounds (U.S. $ 730,000) to fund the Lomox Wales in the UK R & D-based organic light-emitting diode (OLED) technology, new products. The light-emitting materials can be made into the film covering the walls, full of soft light to issue similar to natural light, to avoid shadows and glare caused by light bulbs and other issues. According to reports, this material energy efficiency standards for energy-saving lamps is also now 2.5 times higher.
The new product uses a very thin coating of organic materials and glass substrates, when there is a current, these organic materials will be light. Display using this technology with more light and more energy-efficient features, has been used in mobile phones and other electronic products. However, the existing products in the large area display, reduce costs and extend the life of other aspects to be improved. Carbon Trust and Lomox company of people expressed the belief that technological advances by 2012 will be "light-emitting wallpaper" to the market.
Carbon Trust was founded by the British Government, its purpose is to promote the commercialization of advanced low-carbon technologies to help address global warming. It has invested tens of millions of pounds more than a hundred related projects funded.

British invented the "plant asphalt"
Bedfordshire United Kingdom successfully carried out several experiments show that waste vegetable oil can be recycled to the laying of roads.
Materials Industry Association (Aggregates Industries) doctoral research manager Helen ? Bailey developed a vegetable oil made from the waste called "asphalt plant" (Vegetex) the substance that can replace the asphalt road paving requirements 20% asphalt.
I have described, according to Bailey, asphalt plant to meet all the requirements of environmental benefits. First, it can replace the annual road construction for the UK's 1.25 million tonnes of asphalt, which is very important because the asphalt from crude oil, and oil can never wear. Secondly, the use of waste vegetable oil can reduce the pressure on landfill environment. In addition, because only low-temperature asphalt processing plants, so lower energy consumption. Meanwhile, the use of this material can reduce dependence on expensive imports, resulting in economic benefits.
UK Transport Research Laboratory (Transport Research Laboratory) Environmental Consultants Brandli ? Kedai Er that if the recycling of road lines and durability have not been adversely affected, and the use of waste oil recycling process is not divorced from the existing (now a cyclic process can have a greater environmental benefits), then the asphalt plant can be regarded as a kind of perfect material.

Japan abstracts "green crude" from algae
A large number of microscopic algae in lakes is the potential threat of water pollution, and the Japanese expert has launched its waste to treasure, can be developed efficient, low-cost algae extract from these "green crude" of the new technology.
According to Kyodo News recently reported, although too much algae can cause eutrophication of lakes, threatening water quality, thus damaging the ecological system, but these algae absorb carbon dioxide and has a strong ability of synthetic organic compounds, may be used as bio-fuel raw materials. However, the evaporation of large amounts of water contained in phytoplankton need to consume large amounts of energy, so use algae to produce biofuels is still a lack of feasibility.
Central Research Institute of Electric Power in Japan by researchers add to the algae can be closely integrated with the fats liquefied dimethyl ether, successfully extracted the oil for burning. The researchers explained that when the DME and the algae cells combined oil component, as long as the dimethyl ether at room temperature, evaporation, will be able to extract the oil components.
According to reports, using the above method of oil components extracted from dried algae equivalent weight of about 40%, after the heat of combustion of gasoline equivalent is expected to be a valuable "green crude."

The US used viruses isolated hydrogen from water
According to the American physicist organizational network April 12 (Beijing time) reported that MIT researchers use virus to separate hydrogen from water, the water into hydrogen fuel in the long process has taken a key step in . Research published in the latest issue of "Nature Nanotechnology" magazine.
MIT materials chemist Angela Bell, a team led by thorough simulation of the water separation plants use sunlight and manufacture of chemical fuels to promote their own growth process, carried out on a genetically modified virus, while as a biological scaffold, the Some nano-components together to build the ultimate separation of the water molecules into hydrogen and oxygen atoms.
In the past, researchers used electricity generated by solar panels to separate the water molecules, but the MIT researchers made direct use of sunlight to get hydrogen. Belcher said that while their ultimate goal is to get hydrogen from water, but the separation of oxygen from the water, the technical challenges greater, so the research team first began to overcome the difficulties.
Belcher's team will be non-toxic M13 genetically modified bacteria and viruses, making it a catalyst molecule adsorbed iridium oxide absorption material and a zinc porphyrin, and tied together with them, continuously absorbing materials along the virus to pass the sun, so The virus became similar to the wires of the device, the oxygen can be efficiently separated from the water molecules.
