A recent study conducted by the Pine Street Foundation showed that a dog’s nose may have the ability to detect cancer. A dog’s nose, which was the “medical device” used as part of the research, is believed to be among the world’s most powerful olfactory(嗅觉的) sensors. The study was conducted with 169 subjects 55 of which had been diagnosed as having lung cancer, 31 have breast cancer and 83 control subjects——people without cancer. During the study, five professionally trained scent dogs were used to distinguish between the breath samples of cancer patients and those who were healthy. With an average of 90% accuracy, the research was deemed a success.

The Pine Street Foundation conducted its research on the belief that cancer cells give off a different type of metabolic(新陈代谢) waste product than normal cells. According to the study, the difference is so great that it can be detected by a dog’s sense of smell, including both early and late stages of the disease.

In the conclusion of the study the Pine Street Foundation said that even ordinary dogs may be trained to identify the presence of cancer with only a breath sample. The organization also said that dogs can recognize the disease with astonishing amount accuracy and, finally, that the dog’s detection was not hindered(妨碍) by the presence of age, smoking or stage of cancer.

The Pine Street Foundation plans to continue their research and is currently seeking funding to launch new studies.

Third-generation mobile phones, known as 3G, are the next big step for the telecom industry. Date speed in 3G networks is much quicker than that in present technology. This means users can have high-speed Internet access and enjoy video and CD-quality music on their phones.

  “Mobile data is not a dream; it’s not an option but a requirement,” said Len Lauer, head of a US communications company, Sprint PCS, at a 3G conference in Bangkok earlier this month.

  With 3G, you can forget about next messages telling you yesterday’s news; a 3G phone can receive video news programs, updated four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home.

  Face-to-face video calls

  Don’t worry about getting lost, 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset.

  However, the most impressive part of 3G technology is video calling. With live two-video communication, you can have face-to –face talks with friends and family on your mobile phone.

  Many European countries have already launched the service. In May 2000 the US Government issued five license to run 3G wireless services, while the first 3G phones arrived in Italy in March this year.

  International telecom companies can’t wait to sell 3G in China, the world’s largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops.

  “We need to create a pool of 3G customers before the large-scale commercial launch of the service,” said Fan Yunjun, marketing manager for Beijing Mobile. “ We expect that the 3G licenses will be issued late next year.”

If California were not already so famous for Sillicon Valley(硅谷) and Hollywood, it might be well－known for the groups of water－technology firms in its San Diego County. The reverse－osmosis (RO) spiral module, the technique that supports turning seawater and waste－water into drinkable stuff, began in San Diego in 1964. Today dozens of firms in the area supply many of the world's approximately 13，000 RO plants in places from the Persian Gulf and Israel to Australia and China.
Southern California itself, however, has not so far been a big user of its own technology. This is surprising, given that the whole American south－west faces a water problem. But now as the climate gets warmer and the population increases, there is more agreement that the existing infrastructure, consisting of vast pipes that carry water from the Sacramento Delta in the north and the Colorado River in the east, will not be enough. In places such as San Diego, which has inadequate and salty groundwater and currently imports 90% or its water, the answers must be greater conservation, reusing as much water as possible, and getting most of the rest from the sea.
The first part, conservation, has been widely accepted by the public. San Diego today uses less water with a larger population than it did in 1989, the year water consumption peaked. The second part, water recycling has been a hard sell, because of an unpleasant factor. Americans still use the term “toilet－to－tap” for recycling, even though properly treated waste－water is nowadays completely clean. Singapore made its programme acceptable in part by renaming it as NEWater.
This is where desalination comes in, which means taking the salt out of salt water. A firm called Poseidon Resources is now close to building the biggest desalination plant in America behind a power station by the beach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling, so Poseidon plans to change 104m gallons a day by using the RO spiral module.
Lots of people like the idea. Once fully running in 2015, the plant could produce 10% of the region's water. And there are plans for more desalination plants. Many places would need to take much less water from the endangered Colorado River. But a few people hate it a lot. Joe Geever, an expert in biology, says desalination uses too much energy and that Poseidon plant would kill too much sea life. He understands that there is a role for desalination, he says, but would rather not have it right there, right now, and on this scale.
