BEIJING, Oct. 11 (Xinhuanet) -- Scientists have discovered that blind optimism is related to brain's frontal lobes which are associated with processing errors, according to a British study published Monday in the journal Nature Neuroscience.Scientists at the University College of London scanned brains of volunteers who were asked to estimate their personal likelihood of involving in negative events, like a divorce or cancer,  before and after given the average probability of these events occurring.They found that the volunteers who estimated lower probability (or the more optimistic ones) than the given one raised their estimates a little bit later while those estimated higher probability altered their estimates much more.Through the brain scanner, scientists saw there was less activity in the volunteers' frontal regions when the information given was worse than expected while more activity when the information was better than expected. It suggested that the more optimistic people neglected the negative predictions."The more optimistic we are, the less likely we are to be influenced by negative information about the future," said Dr. Tali Sharot, lead author of the study. He added being optimistic clearly had some benefits, "but it can also mean that we are less likely to take precautionary action, such as practising safe sex or saving for retirement. So why don't we learn from cautionary information?"

SINGAPORE, Oct. 10 (Xinhua) -- A Singapore start-up firm has devised an innovative application to allow phone users to have access to their positioning information within buildings, where traditional global positioning system has often proved inaccurate, local daily Business Times reported on Monday.The firm YFind Positioning System feels that the application can help turn Singapore into the world's first location- intelligent city.Ting See Ho, co-founder of the firm, said the application works by first verifying the GPS coordinates to identify the building the user is in, and then collecting RSSI (received signal strength information) readings off WiFi access points within the building.The information is then sent by the phone to the central positioning server for comparison against records of the radio map of the building, which is calibrated earlier by the company.Ting said the RSSI readings continually fluctuates, making it difficult to estimate a position. This is where YFind Positioning System steps in with its patent-pending probabilistic algorithms to help accurately estimated the user's indoor positions.Once the phone application determines the location, then, it is able to map a course for a shop or other destination within the building where the user wants to go."You can think of it as creating an 'indoor GPS' environment in the buildings where satellite signals cannot be read," Ting said.He said that more than ten organizations in Singapore have approached the company to discuss deployment and partnerships and that it has begun work on three proof-of-concepts.The company's immediate goal is to make Singapore the world's first location-intelligent city before going to other cities, he said.

ADDIS ABABA, Dec. 2 (Xinhua) -- Xie Xiaoyan, the newly appointed Chinese ambassador to Ethiopia and the African Union (AU) on Friday presented his letter of credence to Jean Ping, chairperson of the AU Commission (AUC) at his office in Addis Ababa, Ethiopia.After presenting the credential letter to Ping at the AU headquarters, Ambassador Xie held talks with the AUC chief on the relations and cooperation between China and the union of 54 member countries.The Chinese government has constructed a state-of-the-art office complex and conference hall for the AU with an outlay of around 125 million U.S. dollars, a project that demonstrates the friendship between China and Africa.

SAN FRANCISCO, Nov. 14 (Xinhua) -- Google is running a secret research lab in the San Francisco Bay Area, where the tech giant invests to experiment and invent what may be world-changing technologies for the future, U.S. media reported on Monday.According to The New York Times, at the lab dubbed Google X, engineers are working at some 100 projects from robots, smart refrigerators to Internet-enabled dinner plates and a "space elevator," a proposed non-rocket space launch structure.An unnamed Google engineer familiar with the lab told the newspaper that it was run as mysteriously as the CIA with two officers, a nondescript one for logistics on the company's Mountain View campus and one for robots in a secret location.Scientists working at the lab include many roboticists and electrical engineers hired from Microsoft, Nokia labs, Stanford, MIT, Carnegie Mellon and New York University. Google's co-founder Sergey Brin is said to be "deeply involved" in Google X.The lab is reportedly headed by Sebastian Thrun, one of the world's top robotics and artificial intelligence experts. He teaches computer science at Stanford University and invented the world's first self-driving car.A Google spokeswoman would not confirm the existence of the lab, but said Google likes to invest in speculative projects."While the possibilities are incredibly exciting, please do keep in mind that the sums involved are very small by comparison to the investments we make in our core businesses," she told The New York Times.

LAS VEGAS, the United States, Jan. 12 (Xinhua) -- NVIDIA, the computer chip manufacturer best known for its high performance graphics processors, is looking to make further inroads with the automobile industry by integrating its new Tegra 3 mobile processors in upcoming vehicle models.At the 2012 International Consumer Electronics Show (CES), NVIDIA and Audi announced that all models from the German auto manufacturer in 2013 will use Tegra 3 quad-core processors to power their in-car digital systems.These processors, which are traditionally found in smartphones and tablets, will support the vehicle's digital systems at lower energy rates and also allow for shorter lead times in getting concepts to market.In addition to powering infotainment systems that allow for web browsing and Google Earth integrations, they will also give automakers the ability to replace traditional dashboards with instrument cluster systems, or digital dashboards."By leveraging technology from the very latest smartphones and tablets, Audi is leading the market with innovations that enhance safety and make driving more enjoyable," said Ricky Hudi, the company's chief executive engineer, at Audi's official conference at CES.For Audi, this means that they will be able to offer cars like the next-generation A3 model beginning in 2013, which features an integrated touchpad system and mounted monitor with the ability to render 3D imaging. Current 2012 Audi vehicles house the Tegra 2 processor."It's a natural progression with people getting so accustomed to mobile and expecting it from your automobiles as well. Partnering really closely with automotive OEMs enable us to help them realize the driver experience they're looking to deliver," said Phillip Hughes, NVIDIA's director of automotive sales and business development, in an interview with Xinhua.In addition to Audi, Tesla and Lamborghini will also be including the newest NVIDIA Tegra 3 processor in upcoming models. At this year's CES, Lamborghini is showcasing the Lamborghini Aventador, a nearly 700 horsepower vehicle with the capability of going from 0 to 60 miles per mile in less than five seconds."NVIDIA technology is enabling us to do more with our vehicles and gives our cars the ability to have the technology you'd expect from a car like this," said Kelly Snyder, an event manager with Lamborghini, to Xinhua. The retail price point for the Lamborghini Aventador starts at 382,000 U.S. dollars.More than just powering the car's digital experiences, however, integrating NVIDIA's processors will help the auto manufacturer build better cars by reducing the power to weight ratio that is a key consideration in manufacturing higher performing cars."By moving elements like the odometer to a digital dashboard platform, it reduces the power to weight ratio that is so critical to the design and manufacturing of automobiles like the Lamborghini," explained Snyder.NVIDIA also expects that the integration of these processors will bring the development cycle of the automotive industry up to speed with the consumer electronics industry through Virtual Computing Modules (VCMs) powered by the Tegra 3. These VCMs allow auto manufacturers to quickly prototype and ship consumer technology innovations to automobiles, reducing a development lifecycle that once took seven years, to roughly a year."At the end of the day, our goal is to help automotive OEMs bridge the gap between OEM and consumer technology," said Hughes.
