BEIJING, Aug 4 (Xinhuanet) – A new urine test might help doctors detect prostate cancer and better evaluate a patient's treatment options, according to American reseachers Thursday."This is a tool that men and their physician can use to help them decide whether it's appropriate to get a biopsy now or delay that decision," said lead researcher Dr. Scott Tomlins, a pathology resident at the University of Michigan Health System.The test looks for two genetic markers associated with prostate cancer. The first, called TMPRSS2:ERG, is caused by two genes changing places and fusing together; it is thought to cause prostate cancer. Since the gene fusion is only seen in about half of cancer patients, the test also looks for another marker, called PCA3."We are exploiting some new bio-markers to try to refine the PSA (prostate-specific antigen) test," Tomlins said.

BEIJING, July 27 (Xinhuanet) -- Amazon.com’s e-book reader Kindle 3G with special offers is now the company’s top-selling e-book device, according to media reports on Wednesday.Amazon revealed in its quarterly earnings report that the ad-supported version costs 139 U.S. dollars,  50 dollars cheaper than the comparable Kindle 3G, and costs the same as a Kindle with Wi-Fi connectivity. Many believe Kindle is the most popular dedicated e-book device on the market today.The advertisements will appear only in screensavers (which appear when the reader is in an idle state) and at the bottom of the home screen, so they don’t interrupt readers.“Since AT&T agreed to sponsor screensavers, Kindle 3G with Special Offers is now our bestselling Kindle device,” Amazon’s press release said.Having zoomed past the earlier Sony Reader, and kicked off a wave of competition including the Barnes & Noble Nook and the Kobo E-Reader, Kindle is believed the most popular dedicated e-book device on the market today.

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.

HELSINKI, Aug. 21 (Xinhua) -- The Finnish company Spektikor has recently developed a novel type of disposable heart rate indicator, local media reported on Sunday.Different from a conventional heart rate monitor, it is a speed heart rate indicator designed for first aid professionals and specially used in first aids in major accidents, disasters and other crises.According to Spektikor, the product is consisted of a heart rate sensor with two EKG electrodes and a LED indicator, which are connected by a 35-cm-long wire.In operation, the sensor is placed on a patient's chest and the LED indicator is sticked to the patient's cheek. If the heart rate is within the normal range, the LED indicator will flash green with each beat. If the heart rate is dangerously low or high, the light will turn red.The product will help hospital staff speed up their work considerably as it is not necessary to check the pulse manually. In addition to saving time, it will also enhance safety, as the LED indicator can be seen clearly at a glance.The market prospect of the disposable heart rate indicator is quite optimistic as there is a worldwide need for the product.

SHANGHAI, July 19 (Xinhua) -- Baidu Inc., the largest Chinese search engine based in Beijing, said Tuesday it closed a deal that allows the company to provide download services of music from Universal Music, Warner Music and Sony Music.According to the deal signed between Baidu and One Stop China (OSC), a joint venture of the three music companies, Baidu will pay them on a per-play and per-download basis for all tracks delivered through its MP3 server, said a press release provided by Baidu.Users can have access to the authorized music free of charge, and Chinese songs, both in Mandarin and Cantonese, and some global content provided by the three music companies will be included in the catalogue.Baidu also launched a social music platform called "Baidu ting!" through which users can obtain and share some music-related information and content.Li Xinzhe, CFO of Baidu, described the deal as a "milestone" that can benefit not only Baidu and its partners but also music lovers and the privacy-stricken industry.Wang Bin, secretary general of Copyright Union of Internet Society of China, predicted that it would have a demonstrative effect on the Internet sector.In 2008, Universal, Warner and Sony Music sued Baidu for at least 63.5 million yuan (9.8 million U.S. dollars) in copyright infringement.
