BEIJING, Oct. 25 (Xinhuanet) -- Steve Jobs, Apple's co-founder and former CEO, may be one of the great men who will still be influential after their deaths.The new biography of Steve Jobs is likely to be the top-selling book 2011 of Amazon.com Inc, an online book retailer, according to Amazon spokeswoman Brittany Turner Monday."It could very likely be our top-selling book of the year," Turner said in a statement cited by the Reuters.Steve Jobs, written by Walter Isaacson, former Time magazine managing editor, was landed on shelves in bookstores Monday.But its digital version was reported to be released late on Sunday on Apple's iBooks online store and Amazon's Kindle eBook store.Since its release, the biography, both electronic and physical versions, has performed very well in Amazon.It is the best-selling book on Amazon.com and the top-selling electronic book on the Kindle as well. According to the Reuters, Isaacson was asked by Jobs to consider writing a biography for Apple's former CEO in 2004, when Jobs was going to be operated on for pancreatic cancer.Then Isaacson had more than 40 exclusive interviews with Steve Jobs. The last such interview was on October 5, one week before the giant's death.

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.

WASHINGTON, Oct. 18 (Xinhua) -- Scientists have increased the estimate of the number of humpback whales in the North Pacific Ocean, according to a paper published Tuesday in the Marine Mammal Science journal.The increase follows a refined statistical analysis of data compiled in 2008 from the largest whale survey ever carried out to appraise humpback whale populations throughout the North Pacific.The number of North Pacific humpback whales in the 2008 study, known as the Structure of Populations, Levels of Abundance and Status of Humpbacks, or SPLASH, was estimated at just under 20,000 based on a preliminary look at the data.The latest research indicates the population to be over 21,000 and possibly even higher -- a significant improvement to the scant 1,400 humpback whales estimated in the North Pacific Ocean at the end of commercial whaling in 1966."These improved numbers are encouraging, especially after we have reduced most of the biases inherent in any statistical model," said Jay Barlow, marine mammal biologist of the U.S. National Oceanic and Atmospheric Administration (NOAA)."We feel the numbers may even be larger since there have been across-the-board increases in known population areas and unknown areas have probably seen the same increases," Barlow added.The SPLASH research was a three-year project started in 2004 involving NOAA scientists and hundreds of other researchers from the United States, Japan, Russia and some other countries.It was the first systematic survey ever attempted to determine the humpback whales' overall population, structure and genetic makeup in the North Pacific.

WASHINGTON, Nov. 8 (Xinhua) -- Children with autism have more brain cells and heavier brains compared to typically developing children, according to a study to be published on Wednesday in the Journal of the American Medical Association.The small, preliminary study provides direct evidence for possible prenatal causes of autism.The prefrontal cortex is involved in various higher order functions such as language and communication, social behavior, mood, and attention. Children who have autism tend to show deficits in such functions.Eric Courchesne, of the University of San Diego School of Medicine Autism Center of Excellence, and colleagues conducted direct counts of brain cells in specific regions of the prefrontal cortex in postmortem brains of seven boys who had autism and six typically developing males, ranging in age from 2-16 years. Most participants had died in accidents, but the researchers did not base their selection on causes of death.The researchers found that children with autism had 67 percent more neurons in the prefrontal cortex and heavier brains for their age compared to typically developing children. Since these neurons are produced before birth, the study's findings suggest that faulty prenatal cell birth or maintenance may be involved in the development of autism. Another possible factor that may contribute to the neuronal excess is a reduction in apoptosis, or programmed cell death, which normally occurs during the third trimester and early postnatal life.Though small, this preliminary study examined all relevant postmortem tissue available at the time. The relative scarcity of tissue from very young children may limit future research as well, but efforts to include a larger number of samples are needed to confirm these findings and to identify patterns of age-related changes in autism, the researchers say."Earlier studies of head circumference and early brain overgrowth have pointed us in this direction, but there have been few quantitative neuroanatomical studies due to the lack of postmortem tissue from children with autism," said Thomas Insel, director of the National Institute of Mental Health, in a statement. "These new results, along with an earlier study reporting altered wiring of the prefrontal cortex, focus our attention on this critical area of the brain in autism."
