CHENGDU, Sept. 3 (Xinhua) -- A list of this year's top 500 Chinese enterprises was unveiled in the city of Chengdu in southwest China's Sichuan Province on Saturday.The Sinopec Group was ranked first, with last year's revenues reaching 1.97 trillion yuan (307.81 billion U.S. dollars), followed by the China National Petroleum Corp. and State Grid Corp., whose revenues hit 1.72 trillion yuan and 1.53 trillion yuan last year, respectively.The rest of the top 10 was rounded out by the Industrial and Commercial Bank of China, China Mobile, China Railway Group, China Railway Construction Corp., China Construction Bank, China Life Insurance Co. and Agricultural Bank of China.The list is the 10th of its kind to be jointly released by the China Enterprise Confederation and the China Enterprise Directors Association. The threshold for entering the list was raised to 14.2 billion yuan in revenues, an increase over the 11.08-billion-yuan threshold used during the previous year.Revenues for China's top 500 companies rose 31.6 percent year-on-year to 36.31 trillion yuan in 2010, while their total assets increased by 18.4 percent to 108.1 trillion yuan, the two organizations said.The companies reported profits of 2.08 trillion yuan for last year, a rise of 38.67 percent from one year earlier.They paid 2.73 trillion yuan in taxes in 2010, accounting for 37.3 percent of the country's total tax revenues.

BEIJING, July 26 (Xinhuanet) -- Hong Kong scientists announced that they had determined the idea of time travel is impossible by proving nothing can travel faster than the speed of light.The finding is contained in a study done by a research team from Hong Kong University of Science and Technology. The study was published Monday in a scientific journal "Physical Review Letters" in the United States."The study, which showed that single photons also obey the speed limit c, confirms Einstein's causality, that is, an effect cannot occur before its cause," the university said on its website."By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon." said Professor Du Shengwang, who led the study.The possibility of time travel was raised 10 years ago when scientists discovered the optical pulses in some specific medium might propagate information in a faster-than-light speed."Our findings will also likely have potential applications by giving scientists a better picture on the transmission of quantum information." Du said.

CANBERRA, Sept. 9 (Xinhua) -- Managing other people at work triggers structural changes in the brain, protecting its memory and learning center well into old age, Australia's study revealed on Friday.Australia's University of New South Wales (UNSW) researchers have, for the first time, identified a clear link between managerial experience throughout a person's working life, and the integrity and larger size of an individual's hippocampus (the area of the brain responsible for learning and memory) at the age of 80. "We found a clear relationship between the number of employees a person may have supervised or been responsible for and the size of the hippocampus," Dr Michael Valenzuela, Leader of Regenerative Neuroscience in UNSW's School of Psychiatry, said in a statement released on Friday."This could be linked to the unique mental demands of managing people, which requires continuous problem solving, short term memory and a lot of emotional intelligence, such as the ability to put yourself in another person's shoes. Over time this could translate into the structural brain changes we observed."The findings confirmed that staying mentally active promotes brain health, potentially warding off neurodegenerative diseases such as Alzheimer's.Using MRI imagery in a cohort of 75-92 year-olds, researchers found larger hippocampal volumes in those with managerial experience compared to those without. The effect was also seen in women who had taken on managerial roles in nursing or teaching, for example.The study was presented at this week's Brain Sciences UNSW symposium Brain Plasticity The Adaptable Brain, held in Australia.

SAN FRANCISCO, July 19 (Xinhua) -- Apple Inc. on Tuesday reported strong third fiscal quarter results that top analysts' expectations, citing strong iPhone and iPad sales.For its fiscal 2011 third quarter ended on June 25, Apple reported net income of 7.31 billion U.S. dollars or 7.79 dollars per share, compared with 3.25 billion dollars, or 3.51 dollars per share a year ago.Its revenue reached 28.57 billion dollars, compared with 15.7 billion dollars in the same period a year earlier. International sales accounted for 62 percent of the quarter's revenue.The average estimate is a profit of 5.84 dollars a share on revenue of 24.9 billion dollars.The Cupertino, Califronia-based company sold 20.34 million iPhones in the quarter, representing 142 percent unit growth over the year-ago quarter. It sold 9.25 million iPads in the third quarter, a 183 percent unit increase on a year-over-year basis.The only drawback is the sales of iPods, which had a 20 percent unit decline to 7.54 million from the year-ago quarter."We're thrilled to deliver our best quarter ever, with revenue up 82 percent and profits up 125 percent," Steve Jobs, Apple's chief executive officer, said in a statement."Right now, we're very focused and excited about bringing iOS 5 and iCloud to our users this Fall," added Job.It is the first time since 2008 that Apple's third-quarter earnings does not include the release of a new iPhone, which, slated for launch in September, is reportedly to be thinner and lighter with a faster chip and 8-megapixel camera.Apple has enjoyed double-digit year-over-year percentage revenue growth for the past four quarters. It had previously beaten the average earning projection for at least 29 straight quarters, according to data compiled by Bloomberg.For the fourth fiscal quarter of 2011, Apple's chief financial officer Peter Oppenheimer said the company expects revenue of 25 billion dollars and earnings per share of about 5.5 dollars. Apple has been known for its conservative projections of earnings.Apple has been operating without the daily attention of Jobs since the CEO took a medical leave this January. The Wall Street Journal reported Tuesday that some members of Apple's board have discussed CEO succession with executive recruiters and at least one head of a high-profile technology company.But the people familiar with the matter told the newspaper that it was more of an informal exploration of the company's options and don't appear to have been acting on behalf of the full board.Meanwhile, Apple has recently been busy with a number of legal battles over patent rights with HTC, Eastman Kodak and Samsung.Last week, the U.S. International Trade Commission made an initial ruling that HTC infringed two of Apple's phone patents in its smartphones powered by Google's Android operating system.If upheld, the ruling could let Apple force other Android phone makers to pay significant patent fees.On Tuesday, Google's executive chairman Eric Schmidt said at a conference in Tokyo that Apple's smartphone lawsuits are inspired by jealousy and a lack of innovation in iPhone, noting Google would support HTC's fight against Apple and was confident of a win.

BEIJING, August 1 (Xinhuanet) -- U.S. researchers have discovered a genetic mutation unique to African Americans that links to heighten their asthma risk, according to reports published on Sunday in the journal Nature Genetics.Researchers of University of Chicago found a gene, PYHIN1, and its variations may account for asthma risk in people of African descent. In their study, they examined data from nine previous genome-wide association studies, totaling more than 2 million single nucleotide polymorphisms in 3,246 asthma patients and 3,385 control patient, 1,702 patient-parent groupings, 355 family-based cases, and 468 family-based controls.In the study, the researchers found that between 26 percent and 29 percent of people of African-descent carried at least one copy of the gene.  In particular, one polymorphism of the gene was 34 percent more likely found in African-American and Afro-Caribbean people with asthma.  More interestingly, this variant of the gene is rarely found in Caucasian people and in Latino population, it was found in less than 5 percent.This new variant is part of a family of genes linked with the body's response to viral infections. It is thought to be involved in interferon signaling, which could influence the occurrence of asthma.The team stressed that each gene variant on its own plays only a small role in increasing asthma risk, but that risk could be multiplied when combined with other risk genes and with environmental factors.
