SAN FRANCISCO, June 14 (Xinhua) -- Google on Tuesday unveiled voice search for desktop computers and search-by-image, two new features allowing users to speak their search into the computer and search with the help of images.Speaking at the Internet search giant's Inside Search Event in San Francisco, Mike Cohen, head of Google's speech technology efforts, said its voice search is now available in 27 languages and dialects, an estimated coverage of around 5 billion people or two-thirds of world population.Voice search has already been available in Google's mobile search application from 2008. Adding the feature to desktops is part of Google's strategy to bring mobile innovations to its desktop search.The voice search on desktop performs similarly to voice search on smartphones -- users can click the microphone button and speak the query. It is only available via Google's Chrome browser for now.Cohen noted that the volume of Google mobile speech inputs has increased by six times in the last year.Also at the event, Google introduced search-by-image, which enables users to drag-and-drop, copy-and-paste image URL, or upload the image from the desktop into the search box. They can also use a Chrome or FireFox software extension to add images to the search.Google said the search-by-image feature will be available in most countries and regions over the next few days to Chrome users, noting that it will not collect and store any images that users use.

SYDNEY, Aug. 5 (Xinhua) -- The Western Australian Government announced on Friday that 14 new substances linked to the manufacture of the synthetic drug Kronic would be banned from Friday midnight.The State Mental Health Minister Helen Morton told the Australian Broadcasting Corporation (ABC) Radio on Friday morning that two substances found in Kronic Black would be banned from midnight tonight (Friday night), as well as another 12 others found in synthetic cannabis products.People caught in possession of banned synthetic cannabis face hefty fines or possible jail sentences.The government of Western Australia (WA) in June listed a number of synthetic cannabis products, including Kronic, Voodoo and Mango Kush, as illegal substances.But synthetic drug makers have since released a new product, Kronic Black Label, using a different blend of chemicals they say make it still legal to sell.Police suspect the death of a 38-year-old Perth man is linked to his smoking of the synthetic cannabis product Kronic Black Label, which contains two of the 14 substances to be banned.The man, from Hillman in Perth's south, was rushed to Rockingham Hospital on Thursday night after suffering a suspected cardiac arrest, but he later died.Police now are conducting an investigation to identify the cause of the man's death.The Australian Medical Association has warned that synthetic drugs could cause severe paranoia, anxiety and panic attacks.

WASHINGTON, June 15 (Xinhua) -- Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe, the U.S. National Aeronautics and Space Administration (NASA) said Wednesday in a statement.The discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.By pointing Chandra at a patch of sky for more than six weeks, astronomers obtained what is known as the Chandra Deep Field South (CDFS). When combined with very deep optical and infrared images from NASA's Hubble Space Telescope, the new Chandra data allowed astronomers to search for black holes in 200 distant galaxies, from when the universe was between about 800 million to 950 million years old."Until now, we had no idea what the black holes in these early galaxies were doing, or if they even existed," said Ezequiel Treister of the University of Hawaii, lead author of the study to appear Thursday in journal Nature. "Now we know they are there, and they are growing like gangbusters."The super-sized growth means that the black holes in the CDFS are less extreme versions of quasars -- very luminous, rare objects powered by material falling onto supermassive black holes. However, the sources in the CDFS are about a hundred times fainter and the black holes are about a thousand times less massive than the ones in quasars.The observations found that between 30 and 100 percent of the distant galaxies contain growing supermassive black holes. Extrapolating these results from the small observed field to the full sky, there are at least 30 million supermassive black holes in the early universe. This is a factor of 10,000 larger than the estimated number of quasars in the early universe."It appears we've found a whole new population of baby black holes," said co-author Kevin Schawinski of Yale University. "We think these babies will grow by a factor of about a hundred or a thousand, eventually becoming like the giant black holes we see today almost 13 billion years later."

BEIJING, July 11 (Xinhuanet) -- The pace of China's import growth in June fell to its lowest level in 20 months as tightening monetary policies kicked in, resulting in the biggest monthly trade surplus this year, official statistics show.Import growth is expected to slow in the coming months, thanks to the broad impact of the tightening measures, before picking up in the last quarter, economists predicted.According to the General Administration of Customs (GAC), imports rose 19.3 percent, from a year earlier, to 9.7 billion, the weakest since November 2009.Exports rose 17.9 percent and despite this being the smallest increase since last December they reached a record high of 1.9 billion.The decline in import growth has led to a widening trade surplus, .3 billion in June compared to .1 billion in May. But in the first six months the trade surplus dropped 18 percent, year-on-year, to .9 billion."Import growth was weaker than expected, as imports for China's processing trade weakened and de-stocking in heavy industry continued," Wang Tao, head of China Economic Research at UBS Securities, said."Recent commodity price drops, including crude oil, also helped lower the import bill," she added.June's net imports of crude oil fell 12 percent from May to 19.43 million metric tons, the lowest since October, amid refinery maintenance and slowing energy demand, according to the GAC figures."Decelerating economic growth and tightening measures to soak up market liquidity have reined in import growth, but it is not a cause for worry," Li Wei, an economist at Standard Chartered Shanghai, said.The government is expected to announce economic growth data for the second quarter on Wednesday. Gross domestic product growth is widely predicted to slow from 9.7 percent for the first quarter."The slowdown in import growth will last two to three months or even longer due to both falling demand and possible commodity price drops," Li said.Zhong Shan, vice-minister of commerce, said recently that imports will slow down in the second half, citing the government's measures to cool the economy.The central bank has raised interest rates five times since mid-October, with the latest on July 7, and increased the reserve requirements for commercial banks, the amount they have to set aside, nine times since November. The consumer price index, a major gauge of inflation, surged to 6.4 percent last month, the highest in three years.Zhao Fudi, GAC spokesman, said in an online broadcast on Sunday that higher prices are increasing inflationary pressure, leading to a 14.7 percent gain in the overall price of imported commodities in the first half.Imports surged 27.6 percent year-on-year to 9.4 billion from January to June, as commodity prices rose during the first half. Exports increased 17.9 percent in June, down from 19.4 percent in May."This is because of weaker external demand" from developed nations, Wang said.Exports increased 24 percent, year-on-year, to 4.3 billion during the first half, but exports to both the United States and the European Union, China's two major trading partners, rose by only 16.9 percent."The slow recovery of the global economy and the European debt crisis have added uncertainties to export growth," Zheng Yuesheng, head of the GAC statistics department, said.Lu Zhengwei, chief economist at Industrial Bank, believes that the March earthquake and tsunami in Japan hurt China's exports."The disaster cut off China's imports of parts and components used for mechanical and electrical goods, leading to a decline in those exports" which make up a majority of China's exports, Lu said.As Japanese manufacturers resume full production, or come close to it, in September, China's exports will regain momentum, he predicted.Li Wei agreed. "China's exports keep pace with the global economic recovery. And growth will probably see a turnaround in September" when orders for the Christmas season are usually made, Li said.Many companies in China's coastal regions are far from optimistic, citing rising costs in labor and raw materials and yuan appreciation, as well as shrinking demand abroad.Han Jie, deputy director general of the department of commerce in Zhejiang province, said "exporters in Zhejiang have experienced a disappointing first half, and the second half will not be better".

BEIJING, Sept. 14 (Xinhuanet) -- Scientists had discovered the fossils of a new species of ancient carnivorous fish, National Geographic reported Monday.The newly-found ancient fish, "Laccognathus embryi", is a 1.8-meter-long predator, which was "waiting to lunge out to grab whatever was in front of it," said study co-author Ted Daeschler, a vertebrate zoologist at the Academy of Natural Sciences in Philadelphia, the U.S..It had a jaw filled with sharp teeth that were 1.5 inches long, the Journal of Vertebrate Paleontology described.The fish lived in the Devonian period, 415 to 360 million years ago, which "was a fish-eats-fish kind of world," Daeschler said. "There was a real arms race going. If you didn't have good armor on your body, you were very vulnerable.""It's not just finding the animal - it's also placing the animal in its evolutionary crucible," Daeschler added.Its closest living relative is the lungfish which can survive in the drought, scientists said.Scientists hope the finding can help in their study on the revolution of fishes as well as other species.
