Brazilian scientist bred a kind to send tired library to female recently gene mosquito turns deadlily for midge, it can be used control the epidemic in indulge in wilful persecution of a lot of Latin America country. According to the report, midge of the library that send tired carries a variety of bug intermediary virus and parasite normally, exist in country of all Latin America almost, it is the peddler of the serious infectivity disease such as encephalitis, filariasis, elephantiasis. Scientist of university of Brazilian emperor Paul installs Delie Weierke to say, they breed this kind turns gene mosquito, can reduce amount of midge of the library that send tired effectively, restrain the popularity of contagion thereby. In studying a process, the person such as Wei Erke sends tired library midge to male embedded a kind of special gene, when this kind of male mosquito and feral female mosquito are copulatory, this kind of special gene is accessibility the gene group of female mosquito, subsequent wave action kills female mosquito, because this promotion turns this kind,gene mosquito can achieve the goal that reduces amount of midge of the library that send tired. Wei Erke thinks, with destroy with insecticide the methodological photograph of midge is compared, use turn gene mosquito destroys midge has a lot of advantages, because ” do not pollute an environment, mosquito won’t generate the strength to some kind of medicaments, it is harmless to the mankind and other animal at the same time ” . He estimates, in future inside 5 years, this kind turns gene mosquito can be pushed to the market.

Taller than the person tree form cacti is American Sa the mark of park of melon collect state, also be burglar people the helper’s target, the pilfer that this state park sends to prevent frequency recently cultivates form cacti incident, the plan installs chip of guard against theft for this kind of precious plant. Sa melon collect in the Suo Nuolan desert that national park is located in American south. The statistical data 2000 shows, here is growing to make an appointment with 1.3 million individual plant to cultivate form cacti. This kind of plant can grow 15 meters tall, heft several tons, price can amount to 1000 dollar, among them 9 meters tall this cacti is burglar people most the target of favour. Occupy network of news of American cable television to reported a few days ago, love of Bao uncle · says manager of this state park, the administration prepares to introduce chip of guard against theft, protect the cacti in garden. Press a plan, smaller than coin chip will be made an appointment with below by embedded cacti surface 2. 5 centimeters in. These chip that are coded won’t issue signal actively, the ability after wanting to receiving the signal that gets scanning club however produces reaction, the exploration distance between scanning club and chip asks not to exceed 30 centimeters commonly. Love says, often have near the park lading the lorry course of cactus. After, administrator can use scanning stick, check a car to go up to whether have the cacti that comes out from the smuggle in the park. In addition, execute the law whether to have in the store that personnel still can use club of this kind of scanning to check sale cacti and nursery by the cacti of pilfer. Love says, embedded every expenses of this kind of chip comes for 4 dollar about 4. 5 dollar, although Sa melon collect national park hope introduces chip as soon as possible, but still must consider to evaluate through the environment, make sure chip won’t be right tree form cacti, environment and other live thing cause a harm.

The scientist says the odour of aerospace holds decoct beefsteak flavour and hot metal flavour concurrently 

  As the rapid development of space technology and the ceaseless exploration to aerospace, the mankind is right the appearance of aerospace already no longer unfamiliar, the scientist uses aerospace to become like technical general one Zhang Zhangling’s person uncannily aerospace photograph presents alive person before. But do you know what flavour aerospace is after all? American aerospace bureau (NASA) invited expert disclosed on October 16, the odour of aerospace holds decoct beefsteak flavour and hot metal flavour concurrently. Give realer aerospace environment to train astronaut for imitate, american aerospace bureau was invited technically ” popular medicine of Europe rice eggplant ” Steven Pierce comes to expert of modulation of the standing trustee of the production company, odour odour of development outer space. Pierce expresses, at present about aerospace the clew that is what odour after all is very few. He had asked a few astronaut, they state in the end aerospace walks to return a space to stand and be shucked off space navigation is taken and when helmet, they smell a kind of very special flavour, resemble heating up metallic flavour again like decoct beefsteak flavour already, even among them an astronaut says to resemble soldering the odour of autocycle. It is reported, pierce began to work for NASA this year in August, he hopes to be able to be in the development before the end of the year gives aerospace taste this year. Pierce says: “We had made the taste of decoct beefsteak, but the taste that practice proves to make metal giving heat is a few worse. But the taste that practice proves to make metal giving heat is a few worse..

  Museum of British nature history exhibits since 16 days example of a stick insect, body length of this stick insect 56. 7 centimeters. Researcher thinks, this stick insect is current on the world foregone the longest insect. City of record-breaking Malaysia Sha Ba discovers this stick insect in place before a villager is old. Off hours likes to study Qiu Lun of Zhan of biologic Malaysia man to got this insect from inside this villager hand 1989, present the sample of this bug to museum of British nature history subsequently. This kind of stick insect is science bound new discovery. Prague of · of general of benefit of British researcher humble is in newest first phase ” zoologic classification ” name them in the magazine for ” stick insect of Cha Ni sufficient thorn ” . Previous researcher place collects sample in, the insect with the longest body length on the world also is a stick insect, the name is ” Sailadipeisi is sufficient thorn stick insect ” . But of museum of British nature history this ” stick insect of Cha Ni sufficient thorn ” longer than it １ centimeter. Even if is reached no matter full-length, the truncal length of this stick insect also is insect bound most, achieve 35. 7 centimeters, world trunk is the longest before comparing ” stick insect of sufficient thorn of rich family name ” long still 2. 9 centimeters. Buluoke says · of Paul of researcher of museum of British nature history, without doubt, this insect is the world that at present researcher place discovers the longest insect. Example little England ” independent newspaper ” tall of expert of stick insect of museum of history of nature of England of 17 days of cite treats · Beck Aluoni’s word reports: “Before the body length on the world is the longest with trunk the longest insect already held length record 100 old. Because this discovers longer than their body length insect sense is great. ” this kind ” stick insect of Cha Ni sufficient thorn ” divide outside having breathtaking body length, their egg is extremely special also in insect bound. Both sides of every egg bursa has alary edge, when female insect lays eggs, this kind of alary brim makes egg can follow wind flap, conduce species distributes extensively. Researcher introduction, at present people place discovers ” stick insect of Cha Ni sufficient thorn ” sample book is only 3, come from city of Malaysia Sha Ba entirely. Outside the sample that presents except Zhan Qiu Lun, the others all is collected 2 times in Sha Ba city. Difficult discovery researcher still does not understand ” stick insect of Cha Ni sufficient thorn ” biology and ecological character. They think, this kind of insect may live in rain forest, cause researcher to discover hard. Researcher says, the destruction of habitat of a few insects makes a lot of insect species disappear. People is at present foregone about 3000 kinds of stick insect, they live in tropics and semi-tropical area for the most part among them. Stick insect does not grow in England originally, but 3 kinds of stick insect that comes from New Zealand now already perched to be mixed at British southwest ministry stannic benefit archipelago. Museum of British nature history has sample book of 70 million species. Wait for ” stick insect of Cha Ni sufficient thorn ” after example shows an end, researcher of world each district can undertake study to it through museum.

Medicine of Japanese Tokyo university fastens accessary hospital researcher to discovered a few days ago, gene of kinase of metamorphic and lymphatic tumour appears between is one of causes that cause tumor of nerve mother cell unusually. Tokyo university medicine fastens accessary hospital and Japanese science and technology to revitalize an orgnaization to published news bulletin to say jointly a few days ago, the researcher development such as sincere department goes this courtyard coulee a new technology, can detect accurately those who give cancer gene group is unusual. Apply new technology to be opposite the gene group of tumour of cell of 239 nerve mother undertakes an analysis, the case of illness that researcher discovers 10 ％ is put in the section that gene number adds on 2 chromosome short arms, this paragraph of area contains a gene of kinase of metamorphic and lymphatic tumour only. Researcher thinks, gene of kinase of metamorphic and lymphatic tumour is counted between eye increases, bring about a kinase of metamorphic and lymphatic tumour excessive play action, this and canceration of final nerve mother cell are concerned. Bulletin says, tumour of nerve mother cell is the cancer with common children, do not need to cure can shrink back naturally and disappear partly among them, and occupy what 30 ％ controls case of illness to undertake tumour of cell of sexual nerve mother is opposite all sorts of changing cure all shows repellency, although carry out medullary transplanting, cure rate also is less than 40 ％ . The achievement of Japanese researcher makes clear, if can develop a depressor of kinase of metamorphic and lymphatic tumour, treat denaturation of the nether world possibly gene of lymphatic tumour kinase is abnormal the tumor of nerve mother cell that cause.

Japanese scientist is in new first phase ” science ” the report is published to say on magazine network edition, they use 12 diameters below room temperature 0. The atomic platoon of 7 accept rice listed the least letter sign on the world. Researcher of third class of Sen Tianqing of Osaka college professor reformed some is planted nuclear power microscope, the operation precision that makes its pinpoint achieves １ skin rice (１ skin rice is equal to 0. ００１ accept rice) . This kind of nuclear power is microscopical the change of gravitation holds corporeal appearance construction between the needle with lens extremely fine support and material, with the silicon of this microscope surface of the press close to that make an injection is enclothing stannic substrate, from pinpoint release atom of a silicon, can displacement gives atom of a stannum. Use this kind of appearance, researcher is growing successfully wide the symbol that a silicon arranges with silicon atom on the substrate of rice of each 4 accept ” S ｉ ” . Japanese expert points out, international business ever also used atom to discharge listed letter symbol with machine company and other research organization, but their operation is completed below the environment of extreme low temperature, osaka university is use atom successfully to discharge listed letter symbol first below room temperature. Researcher thinks, this new technology conduces to improve semiconductor performance, perhaps design exact extent to achieve the integrated circuit of atomic class.

The researcher that American Florida city establishs an university is developing a kind of magical accept rice paper, paper of rice of this kind of accept looks like carbon, the １ ／ that specific gravity is steel 10, intensity can be as high as 500 times of steel however. The researcher thinks, prospective hopeful is paper of rice of this kind of accept arrive from TV of the plane make bring revolutionary change. Reported a few days ago according to American media, this kind of magical accept rice paper is called ｒ of ｅ of ｐ of ａ of ｐ of ｙ of ｋ of ｂ ｕ ｃ , it has person hair diameter only by degree of finish the element of 50 thousand carbon tubal account of 1/0 is made, have coppery electric conduction and medicinal powder hot property. Florida city establishs the researcher of the university to express to already developing a respect to obtain significant progress, hopeful of ｒ of ｅ of ｐ of ａ of ｐ of ｙ of ｋ of ｂ ｕ ｃ walks into the real life of people very quickly. Report, this plants ｒ of ｅ of ｐ of ａ of ｐ of ｙ of ｋ of ｃ of the ｕ that use ｂ material of compound accept rice is producible a variety of products such as the TV with the computer with lighter, more energy-saving plane and car, more powerful efficiency, better definition, cause material to learn a revolution with manufacturing industry likely thereby. Report, the defect of ｒ of ｅ of ｐ of ａ of ｐ of ｙ of ｋ of ｂ ｕ ｃ depends on cost costly, can produce in the small lot in the lab only at present, and the level that has not reached ideal in the respect such as intensity. The researcher hopes to be able to perfect manufacturing technology as soon as possible accordingly, make the manufacturing cost of ｒ of ｅ of ｐ of ａ of ｐ of ｙ of ｋ of ｂ ｕ ｃ is reduced quickly, reach the level that competes with current and best synthesis material as soon as possible.

Spanish scientist uses new method to replace the skin to cultivate revulsive style successfully with the hair much abler cell, increased this kind of cell greatly breed effect rate. According to Spain ” the country signs up for ” reported a few days ago, nature puts in two kinds to do a cell: Can the embryonic cell that development organizes into all sorts of human body and consist in the mature cell inside every kinds of organ. Last year, the scientist invented the 3rd kind of dry cell: Revulsive type is much abler cell. This kind of cell is to pass ” defer ” of common skin cell ” biological clock ” (set gene program again) obtain, it has two kinds of afore-mentioned dry cells to use the good point of the respect in medicine, process of Dan Jipei Yo is very difficult however and small effect. According to the report, the scientist of center of medicine of Barcelona second birth uses new method to be able to acquire revulsive style with a hair much abler cell, bred this kind of cell process efficiency to raise 100 times, and the diversity of the proliferous ability of this kinds of many able cell and development and embryonic cell are about the same. Additional, the one big advantage that this kinds of many able cell still has embryonic cell to be deficient in: The gene of much abler cell matchs the revulsive pattern that breeds from the hair of a certain patient to it. Will come so the scientist breeds the dry cell that can treat specific disease likely. According to the report, much abler cell still cannot use the revulsive formula that breeds at present at treating a disease truly, still need to guide through many second virus wait for research, its gene compose reductive arrive ” much can quality ” .

Into where of the be buried after is Jisaihan dead? The archaeologist that this is world each country all the time people the mystery that will cannot defeat solution for years is round. The researcher of school of cent of dagger of alternate of emperor of American California university plans to use now without a variety of ruinous exploration technologies, search Ji Saihan grave. School of cent of dagger of alternate of California university emperor released news bulletin to say a few days ago, the 8 person expedition that a researcher that waits for course by artistic, building and archaeology comprises prepares to head for Mongolia country, the plan uses 3 years of time, use the most advanced exploration technology, for instance remote sensing is explored, the induction of explore ground radar, electromagnetism, law that measure magnetism will locate search Ji Saihan grave. Art of subordinate of school of cent of dagger of alternate of California university emperor, building and archaeology are interdisciplinary the Ai Erbai of the research center is special · Lin Yumin (transliteration) the explanation says, be in the place that has large grave presence, upper landforms always can be affected, use all sorts of advanced techniques to undertake be explorationed integratedly, invite the public to participate in an analysis, hopeful inspect limits to narrow. Lin Yumin says, they will fall to undertake notting have to the target in not fossorial circumstance ruinous explore, make high accuracy block diagram finally, will judge Jisaihan’s graveyard with this. Lin Yumin hopes his group can with Mongolia country government and university collaboration undertake making an on-the-spot investigation. According to archaeologist speculation, cheng Jisai sweat is likely tender river of bury Yu E and Kentehan the somewhere near the mountain range, the birthplace that leaves him is not far. A few experts still think, his son with its member of his a few families also may be buried in this place. But straight consummate century 90 time, researcher just by admit this area undertakes making an on-the-spot investigation, but they did not discover Ji Saihan grave.

   The sensitivity of the excited and fervent, autumn of free from worry freedom of spring, summer — , they exist really: Canadian researcher discovered a kind of basis is different and seasonal the protein with active in person head different level. The season feast that it is not worth in illumination is cleared in cerebral cell clearance ” joy is hormonal ” 5- hydroxide lubricious amine. Winter is depressed — , this is the word that the person with bad mood is apologizing to often be blurted out constantly. Nevertheless it exists really. The excitement of the still has spring free from worry freedom of same existence, summer is fervent the sensitivity with autumn. Researcher is early guess sunshine is mixed dark in correlation of the existence in our cerebra. Now, they proved this in the lab first, can make an explanation to this kind of phenomenon even. The researcher of Canadian Toronto university found particle of albumen of a kind of miniature, their basis spring, summer, autumn, wintry the four seasons is different, the active level in person head is different also. Medical bound estimates, germany has about 80 thousand person every year to get winter is depressed the worry of disease. So far, the doctor changes the mood discretion of this kind of seasonal and alternant sex lubricious amine of hydroxide of 5- of material of main ascribe messenger, of this kind of material decrease to be regarded as to bring about winter together with illumination inadequacy the main reason of depressed disease. Because this kind of disease arrived,spring is met sudden recover from an illness — , to in those days, sunshine broke up dark, the spring that a lot of people like very much is experienced. But how does this kind of correlation act well, what researcher still knows to one part circumstance at least so far is very little. Because illumination is regarded as human body biological clock up to now — , namely the mankind’s inherent biology rhythm — , the most important clock. Illumination still can be passed reduce Morpheus the capacity of hormonal fade black element will adjust Morpheus and sober between alternant. Lack illumination or be to be in the chill with very insufficient illumination is seasonal, the inhibition of black to fade element is reduced. Consequence is, people morning feels tired as before, bring about a mood thereby low. And researcher up to now cannot amine amid acts color of hydroxide of complete explanation 5- why to be planted part. To observe human cerebra medium the four seasons changes, canadian researcher is investigated to what about 100 person that check had by a definite date 4 years. Arrive from 1999 2003, their every other is opposite a few weeks the mood state of the person that check undertakes dogging recording and do cerebrum scanning to them, the chemical material in observing cerebrum is in 1 year in how to change. A kind of protein caused the attention of researcher, people knows it is the vehicle of 5- hydroxide lubricious amine already. This kind of protein falls to keep clear of 5- hydroxide lubricious amine in illumination control the clearance of cell giving a head. Researcher discovery, the seasonal performance that this kind of tiny vehicle is not worth in illumination is very brisk. Apparent, in autumn and winter it undertakes in all area of person head ” sweep ” the job, be opposite at least the cerebrum scanning result of the person that check proved this. “The state of seasonal disposition mood to understanding us has our research positive result main effect ” , researcher is written in their report. This report is published in newest first phase ” common psycho document ” on monthly magazine. “We can explain the relation between illumination and mood finally, understanding arrives why sensitive person often becomes depressed and dejected in autumn and winter. “
