After numerous leaks on the Sony Ericsson Xperia Arc HD (LT26i) is a new model of the manufacturer, LT28at, which is found on the front of the stage with a series of pictures taken since its 13-megapixel sensor.
At this rate, Sony Ericsson will be difficult to captivate audiences at the next CES in Las Vegas that will open its doors within weeks. The Nozomi LT26i, tipped to be baptized Sony Ericsson Xperia Arc HD in its commercial version, has been fanned across the Web. In addition to its technical characteristics, even his official photographs were eventually published.
As if this were not enough, now is another constructor that model of talk: the LT28at. Indeed Xperiablog reported that photos taken with the photo sensor 13 megapixels have surfaced on Picasa. The Google site reduces the photos, but you can still see the high quality of these photos, particularly in terms of color reproduction and depth of field.
Also according to the same source, would be a little monster LT28at Technology Reality Display with a screen of 4.55 inches with HD resolution (1280 x 720 pixels), a dual-core processor clocked at 1.5 GHz and therefore a 13 megapixel sensor with LED backlight. This smartphone is destined for the U.S. operator AT & T. But we hope to see him land in our latitudes since Sony Ericsson Xperia its fate in general in all markets.

A Soyuz rocket took off with three astronauts to the ISS
A Russian Soyuz rocket took off, Wednesday, Dec. 21, from the Baikonur Cosmodrome in Kazakhstan, to the International Space Station (ISS) with three astronauts on board.Oleg Kononenko Russian, American Don Pettit and Dutchman Andre Kuipers flew to 13 h 16 GMT (14 h 16 in Paris) on board the Soyuz TMA-03M. The capsule was placed in orbit around the Earth a few minutes later, as expected. It should dock with the ISS on December 23 to 14 h 20, after two days of flight.Series of scientific experiments
The three men will join and on board the ISS and the Russians Anton Chklaperov Anatoli Ivanichine and American Dan Burbank, which had taken off from Baikonur on November 14.
During their mission about six months, the astronauts will receive the particular goods to be transported by three Russian Progress cargo ships, a cargo ship European ATV and two American vessels.
Dutch astronaut, doctor, is planning a series of scientific experiments from work done by European scholars, but also Canadian, Japanese and Americans. The Dutch will also experiment with a humanoid robot sent to the ISS by a Space Shuttle.
SOYUZ LAUNCH SECOND FROM THE SUMMER
The launch is the second Wednesday of the Soyuz spacecraft performed successfully for the loss of a Progress supply ship that crashed in Siberia in August. This failure had broken a reputation for reliability of the rocket, the strength of its nearly 1800 successful launches, and made the back of the largest Russian space industry in recent years.
Russia is now the only country capable of carrying astronauts to the ISS, since the disposal of this was the last U.S. space shuttle. The United States pays to Russia to transport their astronauts, at least $ 50 million headquarters. The commissioning of a U.S. spacecraft is not expected before 2015.

Renault Clio RS the next will be manufactured in Dieppe, not abroad
While German manufacturers of endless parade with fabulous sales figures, our French manufacturers are struggling to keep their production on our territory. That's still good news for Renault.
It had caused a stir not long ago he yn'ya, the next fourth-generation Renault Clio will be assembled in Turkey for much of its models. After a strong reaction, Renault was then granted to build the next Clio also partly in a French factory, that of Flins.
Today, we learn that Renault has also provided a French-made for the future sports version of the Clio, also known as RS. It will indeed be produced in Dieppe, Alpine Renault factory where 330 employees are working.
The information is relayed by the Usine Nouvelle, which reports the words of the direction of the site. We learn also that the production of the Clio RS 4 will begin late next year.

Who stole the moon? NASA seeks to understand
Nobody move! NASA announced it had stolen the moon. Oh, you can look up to heaven, you will not notice anything. But according to a report, the U.S. space agency would have lost hundreds of pieces of moon.
Since Apollo, NASA researchers regularly prepared pieces of Moon, but also samples of asteroids, Mars, comets, or even ions from the outer layer of the sun. But then ...
Scientists lose them or make them fly. Between 1970 and 2010, 517 samples have been lost in the wild. Of course, it's not much on the 26 000 specimens on loan. But it is their rarity that makes them unique objects. (NASA has in stock 140 000 pieces of Moon, 18 000 meteorite samples and 5000 samples of cosmic dust and comet).
As a result, NASA will identify the best stock, and implement an annual inventory in order to limit these losses.

Climate: the third day, the Durban conference still hopes an agreement
Climate negotiations played overtime Saturday afternoon in Durban (South Africa) to extract an action agenda for the coming years to curb global warming and its devastating announced.Cases in the corridors, workers unscrew the hand stands and removing panels, large entrance hall which plays almost deserted, or almost alone, a man at the piano: the Durban Conference Centre gave an amazing show after 12 days of intense activity with delegates from 194 countries.
Number of ministers, negotiators or NGO activists were leaving to catch a plane, raising questions about the possibility of approving - plenary - a possible agreement in the evening.
The last text under discussion proposes to commit to an agreement involving all countries to be adopted in 2015. The date of its entry into force and its legal nature ("protocol" or "other legal instrument"), however, remained unclear.
The objective of the international community is to limit the rise in global temperature to 2 ° C to avoid runaway climate machine.
"We are now, for reasons of time, in an extremely critical situation," said the German Minister of the Environment, Norbert Röttgen while the conference was originally scheduled to end Friday night.
"We risk failure," added, echoing the French Minister for Ecology Nathalie Kosciusko-Morizet.
Many voices questioned the effectiveness of the strategy of the South African presidency of the conference accusing him lack a lack of direction of tempo.
"Have you ever read Sartre's No Exit?
A meeting with key players in the negotiations began in the early afternoon, but no information is filtered, including Chinese and American negotiators out without comment.
"The bottom line is that people are sitting and talking is what is happening," said Tosi Mpanu-Mpanu, chairman of Africa (54 countries), making its way among the journalists gathered outside the room.
The launch of a "road map" towards a global agreement is the condition imposed by European countries to take on new commitments under the Kyoto Protocol and thus keep him alive.
Only legally binding treaty on climate, whose first commitment period ends late 2012, Kyoto is a highly symbolic for developing countries. Its collapse would be a very negative signal two years after the psychodrama of the Copenhagen summit.
The draft text also refers, for the first time, the need to increase the level of ambition of commitments to reduce greenhouse gas emissions, insufficient to date. According to a study presented this week in Durban, the world has embarked on the path of an increase of 3.5 ° of the thermometer world away from the target of 2 ° C.
Faced with uncertainty about the ultimate outcome of current negotiations, some delegates raised the possibility of a suspension of negotiations as was the case in 2000 at the climate conference in The Hague.
"Have you ever read" No Exit "by Sartre? I'm starting to feel like this after two weeks in the conference center," sighed Twit Kelly Rigg, Head of Global Campaign for Climate Action, a broad coalition of NGOs.

The "double subsidy" Beijing selling energy-saving appliances
HC electronic network: Beijing Municipal Commission of Commerce said on December 1, appliance trade-in policy implementation deadline is tentatively scheduled for December 31, 2011. Thus, the implementation of more than two years appliance trade-in policy will temporarily come to an end. At the same time, Beijing in September this year launched the first nationwide promotion of energy efficient appliances experimental work, to February 29 next year, trade and consumers to buy energy efficient appliances, trade-in to receive subsidies, but also can then obtain energy subsidies. "You could say, 'double subsidy' policy, for the promotion of energy saving and recycling economy in Beijing develop and expand energy-saving appliances consumption has played a positive role." China Video Industry Association Vice President Hao Ya-Bin, "China Electronics "told reporters.
November sales of new single-month record high
Beijing Municipal Commerce Commission's latest statistics show that by "double subsidy" policy good, 1 to 11 months, the Beijing trade sales of new appliances 1.766 million units, the amount of sales 6.78 billion yuan, an increase of 6.5%. One November, a record single-month record, trade-in sales of new appliances 265,000 units, the amount of 993 million yuan sales, growth of 7%, compared to last year an increase of 86.9%.
Reporters learned that, compared with home appliances, home appliances trade policy without the need for short-listed bidding companies, home appliances price, buyer to apply for subsidy payments, and many other steps to reduce the intermediate links, to provide consumers with the convenience. And subsidies for energy efficient appliances more energy-efficient products for the expansion of consumption has played a positive role.
According to the Beijing Municipal Commission of Commerce to the relevant parties, the subsidy policy involves a range of energy-efficiency labeling or two energy-efficient appliances, including televisions, refrigerators, washing machines, air conditioners, computers (equipped with energy-saving display), where to buy an energy-efficient appliances will receive the highest subsidies per $ 300.
Reporters recently visited is located in Haidian District, a large appliance store, a shopping guide staff correspondent calculations, if the purchase price of 4,000 yuan a level of energy efficiency televisions, in addition to obtain 10% of the price of the new TV $ 400 trade-in subsidies, $ 300 can then enjoy subsidies for energy efficient products, received subsidies totaling $ 700, the actual purchase of TV with a 3,300 yuan, the equivalent of playing a 8.25 fold. From this, the "double subsidy" to bring benefits to enable consumers to benefit.
Beijing Municipal Commission of Commerce data also show that since August 2009, Beijing launched appliance trade since the Commerce Department audit subsidies total 1.09 billion yuan, the financial sector subsidies total of 1.03 billion yuan.
Reporters saw at the store, enter 12 months, home appliances businesses who have catching trade of the "last", by Christmas, New Year and other holiday-related promotional activities launched, Beijing appliance market is expected to usher in another consumer. " small peak. "
Energy-saving appliances sales surge
China Institute of Standardization Research shows that if the Beijing air conditioning, energy-saving appliances such as flat-panel TV usage from 50% to 100% of the expected product life cycle (10 years) can save over one billion kwh.
Although the energy-saving effect is very significant, but the higher price is still the impede the popularity of these products one of the factors. Hisense Kelon Marketing Director Yang Hongmin Beijing branch of the "China Electronics News," told reporters that, because of higher energy prices, the market is still relatively low but there are a large number of low-cost energy efficiency of old technology products.
The reporter learned that the home appliance business, these preferential policies so that they benefit a lot. On the one hand, the state capital subsidy by the way, will help to reduce the price of energy-saving products, expanding market share of energy-saving appliances; the other hand, government support for energy-saving products, home appliances will also guide and encourage enterprises to speed up energy-saving technology research and development, improved product mix, technological advancement and industrial upgrading.
*
According to Yang Hongmin said, Hisense Kelon was stopped since 2008, the following three energy-efficient air-conditioning products, is currently 98% of Hisense refrigerators can enjoy subsidies, Hisense washing machine in the 1 to 11 months of sales growth is also very obvious.
Chang Zheng Yi, Beijing Branch Marketing Manager is also on the "China Electronics News" reporter, said, "double subsidy" for businesses is a good policy, according to him, the current level of energy efficiency Changhong TV sets accounted for 90%, Since 2011, subsidized policies, marketing strategies to promote the adjustment of other factors, sales growth of about 20%.
Community awareness of the environment
With the "trade" policy out, deal with the problem of waste home appliances become the focus of consumer concern. Beijing Municipal Commerce Commission's latest statistics show that since August 2009 since the city to carry out household appliances trade, recycle old electrical appliances were 4.086 million units.
Reporters learned that, at present China's home appliance recycling mainly in two ways, one is personal (small traders) recycling, recovery may be renovated later sold to second-hand goods market, or dismantling or burning may sell part of the left , other parts readily confused with ordinary garbage thrown away. This approach not only resulted in a tremendous waste of resources, but also led to environmental pollution, health hazards and many other issues. Another way is through the trade waste recycling by a formal unified recovery management, to get a better classification and recycling.
Hao Ya-Bin, but frankly, there are also regular recovery mode needs improvement issues such as lack of effective policy support, the competent authorities for the specific treatment methods and standards is not clear enough and so on. In addition, due to the limited number of recovery, the current profits of these enterprises also generally low.
It is understood that many developed countries have paid great attention to recycling of resources, such as Japan will be used to pay the recycling fee consumers, appliance manufacturers and importers responsible for recycling and reuse of waste a way to handle household appliances.
China Household Electrical Appliances Research Institute of clean technology, said Lu Jian, subsidies to encourage consumers to use energy-efficient home appliances and appliances out of the waste recycling enterprises to formal processing; In addition, subsidies can effectively guide the home appliance business in the design, production, sales, recycling of the whole industry chain are implanted in the concept of low-carbon, thus completing the upgrade of the green industry. As a result, consumers and businesses are doing to the corresponding social responsibilities.
So to some extent, the "double subsidy" social benefits generated by even more impressive than the economic benefits.

Chilean scientists in thousands of photos recording the dynamic process of glacial retreat
Xinhua San Diego, December 7 (Reporter Yeshu Hong ZHAO) in southern Chile is one of Earth's wilderness areas, where ice is considered the most valuable tourism resources. However, with global warming, glaciers are constantly retreating. Chilean scientists took a year, with thousands of photos recorded accelerated glacier retreat Jorge Monte dynamic process.
Jordi Oliva from the Chi Institute of Science, scientists at the Via Monte Ice Jorge four different locations set up a high-definition camera and positioning system, from January last year to January this year a total of 1445 consecutive shooting photos, visually reproduction in one year reduced the ice nearly 1 km of stunning images.
Glaciologist Andres Rivera said that from 1898, the first contraction of the ice occurred, but slowly. The 1990s began a second contract, in less than seven years reduced by 7 km and along with the collapse. Now, shrinking glaciers speed up speed again, and produce a lot of ice.
Rivera believes that the retreat of glaciers Jorge Monte global warming is one of the most serious consequences, the impact of climate change, where the most significant.
Jorge Monte glaciers in the Patagonia region of southern Chile, following the Antarctic and Greenland ice sheets after the world's third largest, but also Chile, an important part of the southern ice fields. Chile's water management bureau of the study, from 1986 to 2007, the ice in southern Chile has 20 glaciers have undergone retreat, and glacier retreat Jorge Monte phenomenon is most serious.

U.S. space agency (NASA) 5 announced, scientists use "Kepler" Space Telescope discovered a livable
planet. Than any previously discovered planets are closer to the Earth's environment, human migration may be the best choice outside the solar system. Aerospace experts said that this is a human search for the "new earth" of an important milestone on the journey, but to immigrants to the "Kepler-22b" impossible.
Distance: 600 light years from Earth
Location: located in the star system "habitable zone" of the middle
Size: radius of about 2.4 times the radius of the Earth
Time: the period around the star of about 290 Earth days
Temperature: The average surface temperature is about 21 ℃
Environment: the surface of liquid water. Currently, scientists do not know, "Kepler-22b" The main ingredient in the end is on the rocks, gases or liquids
Migration time
After 1 million years
Human beings to leave the solar system
"Kepler-22b" discovery of the entire United States, NASA staff are excited. NASA spokesman Joshua Buck said, to find livable planet just the first step in the search for extraterrestrial life. If the prevalence of such planets around a star, "Kepler" will find hundreds of Earth-sized planet livable, and that means life in the galaxy may be prevalent; If, by contrast, is that the Earth is the only possible a life station.
In microblogging, many users are in the Imagination of mankind to be able to immigrants "Kepler-22b". They laugh: "Everyone has new home! Hope for the future of mankind!" "China's real estate developers pay attention!" ...
But Beijing Planetarium curator Zhu's remarks gave these users into a pot of cold water poured. "Man's current level of technology is absolutely impossible to leave the solar system, now and then it is not possible to immigration!"
Zhu Jin told reporters: "At present, the detector is the farthest human launched in the 1970s of the" Voyager 1 ", but 30 years of flying, to fly to Pluto, it is now near the flight distance is the radius of a thousand solar system one, on the current level of technology, humans leave the solar system at least 10,000 years, to immigration, communications issues, problems, and so the problem of human life are overcome, it is impossible to human migration to the "Kepler - 22b" . "
"Although the sinking planet may indeed very good, but want to do are two different things, in order to" space migration ", the human level of technology required can not imagine the high point of our present level, the human has been able to run to Mars is a very big step forward, even if Mars will not be able to come back. "
Reuters reports that the planet may always remain "sunny" good weather, is likely to have for life. This is mainly due to its rotation law makes it always a side facing the star. The AFP believes that "Kepler-22b" Although we are sure appropriate home planet, but it does not mean that there must exist life.
Existing spacecraft to the new earth to be 1160 years
Existing man-made spacecraft, is the fastest flying to Pluto when the number of the "New Horizons" spacecraft, its speed is currently about 15.5 km / sec. If the speed to fly 600 light years away, "Kepler-22b", about 1160 million years to reach. Even the star closest to the sun near Centauri star, from 4.22 we have enough light. The "New Vision" was present, then flying speed, arrived next star is at least 8 years. Therefore, in accordance with the existing level of technology mankind, like the possibility of migration of the planet is almost zero.
Livable Planet
47 planets and satellites
The second candidate to enter the Earth
6, according to British media reports, scientists have begun to create a system of "Livable Planet Guide", the so far discovered the planet for future human migration categories. It is reported that 47 human planets and satellites may be moved to meet the human condition.
University of Puerto Rico's laboratory livable planet known to man, more than 700 types and their respective planet's solar system analysis, found that the vast majority of life on the planet do not have the conditions of survival, of which only 47 stars into the "second a global "list of candidates.
This tutorial uses innovative assessment criteria, such as terrestrial index habitable zone distance, classification systems, and with the Earth in the past, present results of the comparison. The results showed that only two known planets in line with the guidelines livable level, which is code-named Grace 581d and HD 85512b the planet, the other 15 planets and 30 satellites into the candidate list.
Livable condition
Longevity with water and bodyguards
Astronomers lists a livable planet, planet or satellite need to have the three conditions.
1 liquid water: Water is the source of all life. Since life can not do without water, the search for extraterrestrial life search for the essence of liquid water.
2 life: making life process requires a very long time, so there is a galaxy have life, life is not its central star is too short. Generally accepted that the central star of life to reach at least 10 billion years, it's possible to nurture life-line galaxies.
3. "Bodyguard": galaxies with a line of giant gas planets are also important number of conditions. In our solar system, Jupiter and Saturn belong to the giant gaseous planet, they have great quality, in fact, act as Earth's "bodyguard." They like the baseball glove to resist the invasion of the comet on the Earth, or to attract possible collisions can deviate from the Earth's comet.

What is a habitable zone?
If we put all life on earth and their needs at different stages of evolution to be summarizes the different conditions, these conditions are extended to the necessary conditions for the planets, the sun is a star system or even the conditions of the conditions, there is a "livable space zone "concept.
According to NASA defined in the "habitable zone" of the planet, a planet with the means to maintain an appropriate distance from the parent star, and thus to provide the conditions for liquid water on its surface. Stars in heat transfer medium to the planet, the planet is neither too hot nor too cold. This distance will be based on the state of the parent star changes brightness of the star distribute heat more high, the far distance, calories less stellar distribution, the closer distance. "Habitable zone" between the planet's surface temperature is about minus 17 degrees Celsius to 93 degrees Celsius.
To the solar system, for example: solar system eight planets, only pleasant temperatures on Earth, so that long-standing water in liquid form on the surface above. The fundamental reason is the distance from Earth to the sun neither too close nor too far, solar radiation received just fine. The sun around the area to meet this condition, it was called the "habitable zone."
Discovery
How Kepler
Find a new Earth
Kepler telescope, by observing stars - cyclical changes inferred the existence of the planet, suggesting that the process takes at least four times to confirm.
The planet itself is not luminous, so direct observation very difficult. However, if the non-luminous planets through the front from the star, will block part of the star, causing the brightness of stars we see a little dark in a short time, then back to normal again. If the phenomenon of periodic dimming of stars that appear, at least 4 times observed, you can determine where there is a planet we can not see. This method is the so-called "transiting Act."
"Kepler-22b" is found in this way to the star, Kepler telescope to approximately 290-day cycle, the occurrence of starlight dimmed and restore a normal phenomenon. According to stellar brightness dimming rate, astronomers determined the planet's radius is about 2.4 times the Earth; the basis of this phenomenon occurred in cycles, astronomers calculated the orbit of the planet.

PM2.5 invisible killer
Overcast weather so more and more Chinese PM2.5 a public notice in English and numbers jargon. In fact, many Chinese and foreign scholars have already confirmed that it is hidden in the air, not only will harm human health, but also to society difficult to restore economic losses.The so-called PM2.5, is airborne particulate matter, less than 2.5 microns in diameter. Because these particles are too light, natural subsidence fall to the ground hard, but long-term floating in the air, not only small to see, but small enough to be even directly into the blood into the alveoli, and the body's cells "struggle" and harm These cells. To some extent, calling it "the killer" is not an exaggeration.
PM2.5 how to "conviction"
Scientific information from the public to see, a lot of research on PM2.5 focused on the lungs.
Researchers start from the lungs of toxicology: the PM2.5 daily for 4 1 rats exposed continuously for 3 days. Lung lavage fluid of these rats and lung tissue biopsy analysis found that, PM2.5 can cause lung vascular permeability changes in pulmonary cell damage and increased oxidative stress, in the high dose exposure group, exudation of inflammatory cells in rat lung, pulmonary edema interval.
Collected in 2009 an experiment in the atmosphere in Beijing urban PM2.5, human alveolar epithelial cell line (A549) as a role model for toxicological studies. In this experiment, to 25,50,100,200 μg / ml, such as different exposure conditions found that, with increasing exposure concentrations, PM2.5 can cause these cells to inflammatory injury.
"All evidence suggests that, at present these small particles on the cell injury is public opinion." China Academy of Engineering School of Shi Wei Fu-sheng told reporters that when these small things into the body, usually directly to the bronchi and alveoli, or even into the blood, the adsorption of heavy metal oxides PAHs and other carcinogenic substances or harmful.
A study published this year by a nickel-mining and refining area for PM2.5 collection area. The researchers found that nickel-polluted atmosphere, PM2.5 nickel dose is 65 times the experimental control area, the long-term exposure to PM2.5, the high concentration of nickel will increase the damage to cells. The experiments used to test the cells called "endothelial cells", is a continuous coating layer of the lining of blood vessels in the cell populations. In the researchers view, not just blood and tissue within the cortex of the barrier, the damage and dysfunction with a variety of diseases are closely related, including hypertension, coronary heart disease, diabetes, chronic renal failure.
Peking University School of Public Health, Professor Pan Xiaochuan published a paper in 2004 to 2006, when the Peking University campus daily average concentration of PM2.5 observation points increases, about 4 kilometers away in Peking University Third Hospital, cardiovascular disease also increased the number of emergency patients.
"We use time-series analysis of data collected, analyzed, PM2.5 concentration of 10 micrograms per cubic meter, the hospital's emergency department patients with hypertension class will increase 8%, cardiovascular disease will increase." Pan Xiaochuan said.
In March, the Shanghai Environmental Protection Bureau of a project to study the quantitative evaluation of the residents of a city health hazards caused by PM2.5 and its economic losses. The results show that the city's haze pollution factors in 2009 residents of PM2.5 health hazards caused by a total of 2.461 billion yuan of economic losses, loss of 377 yuan per capita, the city accounted for 0.17% of GDP in 2009.
Studies have shown that from the economic losses caused by various diseases of view, cases of the respiratory system caused by the biggest economic losses, accounting for 76% of the total economic losses, but the disease than asthma, respiratory diseases are more susceptible, in 2009 the city asthma prevalence of 19,589 cases. The study also showed that air pollution caused by the different regions of the residents of different health risks of economic losses, such as the 2004 Tangshan air pollution harmful to the health of residents, per capita economic losses of up to 414 yuan / person; Liaoning Fushun residents' health caused by air pollution, loss of small, is 153.15 yuan / person; the same period, Shanghai residents' health caused by air pollution, losses of up to 315.95 yuan / person.
PM2.5 how to "attack"
Wei Fu-sheng told reporters that, in general, more than 10 microns in diameter particles, will be blocked out in the nose; diameter of 2.5 microns to 10 microns between the particles can enter the respiratory tract, but with the spitting, sneezing is part of the excreted ; and less than 2.5 microns in diameter, fine particles, but it will pass the lower respiratory tract, is less than 2.5 microns can enter into the alveoli, and exchanged into the body through blood vessels.
If the enlarged view of these small particles, they are not necessarily circular or square, and irregular shape. Said Wei Fusheng, a small part of these particles is naturally formed in the dust, the vast majority of secondary pollution caused by human behavior, such as sulfur dioxide, nitrogen oxides, ammonium sulfate, ammonium nitrate and other particles. Many of these particles is due to incomplete combustion of fossil fuels produces organic carbon, sometimes in high-temperature coal-fired power plants to generate carcinogens in the cooling of these small particles are adsorbed into the body.
Said Wei Fusheng, such small particles is difficult to natural subsidence, in the air, stay for a week or even months, have their own effects on the respiratory system, causing coughing, discomfort. And small particles on the adsorption of carcinogens, but also lead to high incidence of cancer.
December 5, Tsinghua University, Shi Yigong Bowen said in the past two years, he often painful because of air pollution. His chronic pharyngitis gradually increased since the beginning of 2010, encountered pollution days, "like throat blocked a thing, the pharynx does not survive, but do not spit out, very hard to accept. I do not know how many like me, put this in a serious air pollution. "
Appears in the Pan Xiaochuan, a variety of adsorbed particles was more deadly toxic chemicals.
He told reporters, these because industry and other human activities, incomplete combustion and emission of small particles, itself consists of a certain composition of silica and carbon. In other words, they are "born" of the moment, may be innocent harmless, the only feature that is too small, too. However, the same concentration, the finer the particles, the number more. Than PM10, PM2.5 to be several times the surface area, adsorption of toxic substances in the air will be more.
When the adsorption of PM2.5 carcinogen, there is carcinogenic effect; adsorption of teratogenic, there are teratogenic effects. It is through the lower respiratory tract, deep into the lungs, and it carries the harmful gases, heavy metals will dissolve in the blood.
Since PM2.5 easier for the elderly and children who "get angry", the researchers are concerned about the "killer" may be close to them. One study found that living near main roads in Beijing urban children exposed to higher levels of individual PM2.5. And in 2008 published a paper in September, the National "Eleventh Five-Year" Technology Support Program funded projects, determination of Beijing elderly people in a community of pollutants in the winter when the level of exposure is higher.
Yigong Shi 2008 from Princeton University, chair professor positions for life to return the resignation of the incumbent president of Tsinghua University, School of Life Sciences, but two years, his mood "has been as good or bad air quality changes "because" everything is for our children. "
In his view, air pollution on children's development, mental health will be adversely affected. Frightening is that these effects will generally not be apparent for months or even years to detect, and perhaps some long-term air pollution by the people you will never be aware of its impact ... ... the most frightening thing is that ordinary people to air pollution there is not enough awareness, under normal circumstances would not take the initiative to appeal. While the patient is difficult to diagnose whether the air pollution caused by disease.
He said the pollution of air pollution more dangerous than others. First, the victim up. Unless living in the filter, everyone will suffer. Second, almost impossible to protection. We worry about pollution, you can install a filter of harmful substances; worried about food safety, you can choose some of the more secure food or washed before eating. There is no way to deal with air, because air pervasive, everywhere. Up is fitted in the office and home air filter, but the effect is limited.
How to "apprehend" PM2.5
PM2.5 everywhere, but people can not live in the hood yard. We hope the public, at least know that "rival" power to protect themselves.
Liu Changfeng located in Beijing, a Fortune 500 company to work. Spare time, he took the detector, to compare the subway, taxi, bus, cycling the four modes of transportation. He found that there is no second-hand smoke on the subway, there is no ground on vehicle exhaust emissions, and therefore PM2.5 value of the minimum. So he gave up riding in spring and autumn every year, try to take the subway. He found the office closed in PM2.5 values acceptable to give up going out to eat lunch on the second floor in the office of the meal. He returned to his home, planted 27 pots of green plants, although his mind clear, this is of little use.
This instrument is the detection of natural knowledge that he asked the agency from Darfur borrowed, in Liu Changfeng view, this instrument by the humidity, the air can not be seen in the small water droplets and dust. So they are ready to replace equipment, making this test in a more scientific direction.
Pan Xiaochuan of the research team adopted a "most original" method "apprehend" PM2.5.
This method is like using "shrimp cage" catch "prey": the researchers used specialized sampling head, which is a membrane, the entrance surface of a certain large particles to enter, only the "small fish shrimp." can be captured in, come in to ensure that their leaving. This "shrimp cage" placed in the sampling point 24 hours later, brought weighing, the extra weight is the weight of small particles are.
Pan Xiaochuan said that with the current popular detector and other equipment for testing, the technical conditions is not perfect.
Environmental Science and Engineering, Fudan University, Atmospheric Chemistry Research Center, Zhuang told reporters that China's test of PM2.5, whether technically or economically not difficult. Fully mature technology with international technical standards, professional testing equipment for each of about 10 million, in Beijing, Shanghai, Guangzhou and other cities with such a device is completely capable.
Of PM2.5 in the apprehension and conviction, in fact, is not new. Wei Fusheng was the chief engineer of the China Environmental Monitoring Station, back in the 1990s carried out the impact of air pollution on respiratory health study. He told reporters that the United States has not yet developed policies for PM2.5.
Wei Fu-sheng told reporters that the United States, 1990s PM2.5 study from a theoretical point of view, the U.S. health sector development and environmental protection departments urged PM2.5 standard, but the industry sector and the entrepreneurs are against the government, there are some objections the sound. Because once the development of standards, criteria to determine the scope of the PM2.5 into governance, means that companies and society should pay a higher cost and price. Environmental protection departments to collect evidence, a lot of money and effort to carry out related research.
Wei Fusheng said the United States to develop PM2.5 standard game lasted nearly 20 years. (According to "China Youth Daily")

IBM demonstrated the first integrated circuit memory block of said flash memory is expected to exceed
According to the United States, "Technology Review" magazine, IBM Corporation in Washington at the International Conference on electronic devices demonstrate the first integrated circuit memory block samples. This revolutionary new device combines computer storage capacity of traditional hard drives and flash-quick operation and durability characteristics. IBM said that the track density memory storage and manufacturing costs are expected to go beyond the flash.
IBM was first proposed in 2008 a "track" and the concept of computer memory, said memory circuit will replace the hard disk after 10 years. Integrated circuits responsible for memory read and write data storage components integrated in one chip, and after showing the various components of the memory circuit is located in a different place.
Track the information stored in memory nickel-iron alloy nano-metal online, different parts of nanowires by controlling the magnetic track to get the number 0 and 1. Nanowires of about 10 microns long and 150 nanometers wide, 20 nm thick, one end of each nanowire is connected with the circuit, which produces precise control of the electronic pulse used to write data to the electronic spin as a track within the nanowires. The top of the other end of the nanowires have other layers, so that track movement along the nanowires. Across the layer, a device that can detect track boundaries between reading out data.
New sample from the IBM labs in the Niuyueyueke City complementary metal oxide semiconductor (CMOS) manufacturing technology and are currently the scientific community in general to use the technology to manufacture semiconductor devices and a variety of processors. First proposed the concept of track memory and led the project, said Kim Stewart Tepa, which indicates that you can track memory for commercial production, but also need to be streamlined and improved.
Prospects of this technology depends largely on a single nanowire can be used to store a lot of very dense track data. Parkin said they are currently studying how to track as much as possible into a nanowire, the experimental results show that the nanowires made of different materials perform better.
The use of nickel-iron alloy sample is the so-called soft magnetic materials - are easily magnetized and the external magnetic field to the magnetization. Parkin team is testing the use of hard magnetic materials, hard magnetic materials is not easy to magnetization, and more little harder, be more easy to put a lot of tracks in the nanowires.
From the drum, tape to disk, the computer has been inseparable from the head to read and write 0 and 1. However, technology is fast, less than 20 years ago, CD-ROM drive of the territory invaded; less than 10 years ago, U disk to a floppy disk and floppy drive out of the arena. Today, large-capacity disk and memory fast, lightweight and durable as one, and finally put a magnetic device ruthless. A bunch of hard drive technology with IBM's patent did not stop the pace of technological revolution. "Enterprise is the main innovation" was at IBM who has been fully reflected.
