Gene modification technology pioneered by Taipei-based Academia Sinica is shaping up as the best solution to Xanthomonas wilt, a bacterial disease plaguing Uganda’s banana plantations, the government-backed research organization announced April 14.

“The technology has been used to grow disease-resistant trees that are now at field-crop testing stage,” Academia Sinica officials said. “Ugandan scientists see the development as their best option in battling this widespread form of banana blight.”

According to the officials, a research team led by senior scientist Feng Teng-yung identified two sweet pepper genes that can protect plants such as bananas, potatoes, tomatoes and rice from Xanthomonas wilt. “This is a significant discovery as the disease causes damage estimated at around half a million U.S. dollars each year in a number of Sub-Saharan states,” they said.

“Uganda is particularly concerned about Xanthomonas wilt as bananas are the country’s staple food and No. 2 cash crop. An estimated 30 percent of its trees are infected, threatening 75 percent of the country’s small farmers,” the officials added.

Academia Sinica said it licensed the technology at no cost to the nonprofit African Agricultural Technology Foundation
, which is overseeing the testing program in conjunction with the International Institute of Tropical Agricultural and the Uganda National Research System. (JSM)

China's leading ultra-high voltage (UHV) electricity transmission technologies will be used in a hydroelectric dam project in Brazil, the State Grid Corporation of China (SGCC) announced Wednesday.

The SGCC's technologies will be used at the Belo Monte Dam in the Amazon River Basin to transmit electricity 2,000 kilometers away to Brazil's developed regions in the south and southeast, according to an agreement between SGCC and Brazil's state-owned energy company Centrais Eletricas Brasileiras (Eletrobras) signed in Beijing Wednesday.

"The SGCC is a world leader in UHV electricity transmission and smart grid technologies, so we invited it to participate in the project," said Edison Lobao, Brazil's minister for mines and energy who accompanied Brazilian President Dilma Rousseff to attend the meeting in Hainan Province Thursday of emerging "BRICS" economies (Brazil, Russia, India, China and South Africa).

"China and Brazil share similarities in development of energy and electricity. They both lack oil but have sufficient hydraulic energy. The cooperation between the two nations could help both sides better address the same problems in the development of their energies," the SGCC said in a statement emailed to the Global Times Thursday.

"Brazil's plan to develop its hydraulic energy and power plants requires leading UHV electricity transmission technologies, which China has, making it a foundation for the two countries to cooperate in the field," the statement said.

China has mastered the core technologies of UHV electricity transmission and the capacity to manufacture them over the past five years. It has also built and operated three UHV alternating and direct current transmission lines, which can achieve large-scale, long-distance power transmission.

The SGCC is also the world's largest utility company and operates the largest power grid in the world.

Shu Yinbiao, vice president of the SGCC, said the company would build a joint venture with Eletrobras, to invest in and operate the dam project.

The Belo Monte Dam, the world's third largest hydroelectric dam after China's Three Gorges and Brazil's Itaipu Dam, will start operation in 2015 with an installed capacity of 11 million kilowatts.

The SGCC acquired seven Brazilian power transmission companies for $989 million last December, becoming Brazil's fifth largest electricity operator.

China became Brazil's largest trade partner in 2009. Bilateral trade between the two countries reached $62.6 billion last year, up 47.5 percent from 2009.

Starting a Food Revolution
Tag it:Written by John Berthelsen
Tuesday, 19 April 2011
Chinese scientists take on the feeding of Africa

In February, Dr Li Zhi-Kang, a senior Chinese molecular geneticist, led a delegation of 15 international plant scientists to Africa with the aim of starting nothing less than a food revolution

The vehicle for the revolution is a groundbreaking new rice developed by Li, the chief scientist with the Institute of Crop Sciences at the Chinese Academy of Agricultural Sciences in Beijing, and hundreds of plant scientists across the world at a cost of $50 million.

Li, also a geneticist with the International Rice Research Institute (IRRI) in the Philippines, is the father of Green Super Rice, developed over 13 years through the painstaking crossbreeding of hundreds of strains of rice to fashion plants that are resistant to diseases and bugs, needs no fertilizer and raise yields dramatically.




Green Super Rice looks to be the successor to the Green Revolution of the 1960s that was led by Dr Norman Borlaug, who won the Nobel Peace Prize in 1970 for his efforts.

More importantly, it was developed using a new plant breeding system that Li and his fellow scientists, particularly Chinese ones, are spreading from rice to millet to wheat to barley to soybeans, even to cotton. Li says Green Super Rice can increase yields in Africa by six-fold, to as much as six metric tons per hectare. Already Chinese scientists have doubled yields of millet, a staple for millions of Africans.

“Our goal is to work together with African science people to transfer the technology,” Li said. “In the second phase we will work together to develop a new type of rice there.”

It is a big undertaking. In just one project along the Niger River in Mali the trials use 112 different Green Super Rice hybrids and another 33 inbred varieties.

Under the aegis of the Green Super Rice Program, Li and his fellow scientists visited Mali, Senegal and Mozambique to work on a seed production and distribution system that is designed to eventually feed millions of Africans a more nutritious and plentiful diet. The scientists were drawn from IRRI, the African Rice Center, Chinese universities and several African institutions.

In Africa, they are being aided by the Bill and Melinda Gates Foundation, which put up $18 million. With the aid of the Gates Foundation, the Global Rice Science Project (GRiSP) is seeking funds to expand into seven countries across Asia and seven in Africa. Some 260 people have been trained from public and private centers, including in Africa, on the use of breeding and seed production technology and now are working to put it into the hands of farmers.

But, said Dr Jauhar Ali, a plant scientist and Asia Green Super Rice Coordinator for IRRI, “We have to find some private sector funding to help us. No company is willing to establish anything in Africa.”

Chinese companies are providing some assistance. A Chinese engineering construction company working in Mali, Ali told Asia Sentinel, “wants to do some goodwill” and undertook the development of 1,000 hectares of land for rice as a goodwill project.

But more help for Li and his colleagues is urgent. The International Food Policy Research Institute in Washington, DC, says spending for agricultural research and development in Africa has stagnated or fallen in most of the region.


“In a survey of 32 African nations, the study found that investment in agricultural R&D had rebounded in many of the larger countries, primarily Ghana, Nigeria, Sudan, Tanzania, and Uganda,” the IFPRI said last week in a prepared news release. “However, in 13 countries, spending actually declined. Even where funding did increase, much of the money went to boost low salaries and rehabilitate infrastructure and equipment after years of neglect.”

That unfortunately coincides with growing concern that the weight of the world’s population, estimated to reach 7 billion later this year, will simply make it impossible to feed them all.

Against this is arrayed a painstaking process of plant improvement that began in the mid-1990s in China and holds enormous promise – without genetic modification from proprietary inputs sold by for-profit giants such as Monsanto or Cargill.

"Zhang Hybrid Millet," or ZHM, which is named for its originator, Chinese scientist Zhao Zhihai, doubled production to more than 12 metric tons per hectare. It has been introduced by the United Nations Food and Agriculture Organization in 10 African countries including Ethiopia, Cote d'Ivoire, Nigeria, Ghana, Benin, and Senegal. According to the state-owned China Daily, it has been planted on 266,666 hectares of farmland in 11 provinces in China, increasing annual output by 100 million kilograms. As with Green Super Rice, the seeds are drought-resistant, water-economic and high yielding.

Dr Ali says the method of producing the new strains is perhaps even more important than the rice itself. “This technology has created 50 varieties of different plants,” he said. “This is very exciting. We never expected this to happen. [Other scientists] started doing it and it is spreading very rapidly.” Indeed, he says, the pace is picking up. Although Green Super Rice has taken 13 years to develop, today, mature varieties are being completed in five years or so.

Ali calls the combined approach, which for rice is centered in GRiSP, “pro-poor.”

“We do not promote private production. With the Chinese Academy of Sciences, we are promoting local companies in these countries. Benefits must go equally. We are very cautious about that,” he said.

Access to the products the partnership is producing is free. The hybridization process is continuing.

“We are trying to breed in local milieus to customize the products for them,” he says. “These materials will flow to all of these countries. We are teaching them the breeding strategies. We try to develop local resources to enable them to breed more efficiently, more precisely. Molecular genotyping will be supported in all Asian and African countries, training [of local scientists] to do the servicing of the genotyping so that these countries will be on their own feet. They will be able to produce to their own requirements. These are people who have never seen a bag of fertilizer.”

For Li and his colleagues, this has meant going back to primal, pre-Green Revolution rice to start over. In the 1960s, when Borlaug led the project to develop a short-stemmed dwarf rice that staved off a world famine, it raised yields nearly five-fold and kept billions alive.

But that rice, IR8 and its successors, required intensive fertilization and pesticides, which have polluted rivers and estuarine deltas, creating zones of oxygen-depleted waters where the rivers run into the sea. China, Li said, uses about a third of the world’s fertilizers on about 7 percent of the world’s land.

To give an indication of the complex process now underway, the original launch of the rice breeding program involved scientists from 18 countries and 36 institutions. As many as 2,000 Chinese scientists worked on the project for more than 10 years, taking hundreds of donor cultivars from dozens of countries, identifying the variations in the plants’ responses to drought, global warming and other problems. For instance, in the last four decades, climate change has driven up temperatures in the northern province of Heilongjiang by 2.5 degrees Celsius. The change has allowed rice to be grown where it was never grown before, but it has put tremendous strains on plants of all kinds.

“Backcross breeding,” as the process is known, involves crossing a hybrid with one of its own parents, or with one genetically like a parent, then screening the resulting population to find the improved strains. Ultimately they examined backcrosses from 46 parent plants and 500 donors. Then they pooled them across different traits by using molecular markers.

In one study, it took researchers six years to backcross breed three recurrent elite rice lines with 203 diverse donors to improve resistance to pests, salinity, submergence and zinc deficiency.

It is expected to take two more years to create rice that can be grown in bulk in the African nations where the project is going forward. The task is urgent. Rice consumption on the African continent is growing at 6-7 percent a year and causing a growing shortfall. The continent is importing 10 million metric tons a year, costing $4 billion a year.

"Taiwan-U.S. researchers work on breast PET-MRI
April 15, 2011
by Brendon Nafziger, DOTmed News Associate Editor

Taiwanese and American researchers are working on a device to detect breast cancer that unites PET and MRI technologies.

The project brings together National Cheng Kung University with the U.S. government-run Brookhaven National Laboratory and privately held American company Aurora Imaging Technology Inc. to develop the hybrid system, Taiwan Today reported Thursday.

The international public-private partnership has ambitious goals. The chair of Brookhaven's medical department, Gene-Jack Wang, said the new system should be able to spot breast tumors when they're only 0.2 centimeters big, according to Focus Taiwan. Current technology can only spot such cancers when they reach 4 centimeters, Wang said.

Cheng Kung researchers said it would also speed up diagnosis, from 30 minutes to under five minutes.


The team hopes to have the device in commercial production by Aurora in the next five years. Aurora, based in North Andover, Mass., makes breast MRI machines."

Super-Small Transistor Created: Artificial Atom Powered by Single Electrons

"Super-Small Transistor Created: Artificial Atom Powered by Single Electrons

ScienceDaily (Apr. 19, 2011) — A University of Pittsburgh-led team has created a single-electron transistor that provides a building block for new, more powerful computer memories, advanced electronic materials, and the basic components of quantum computers.

iAXc4.jpg

An atomic-scale depiction of the SketchSET shows three wires (green bars) converging on the central island (center green area), which can house up to two electrons. Electrons tunnel from one wire to another through the island. Conditions on the third wire can result in distinct conductive properties. (Credit: Image courtesy of University of Pittsburgh)

The researchers report in Nature Nanotechnology that the transistor's central component -- an island only 1.5 nanometers in diameter -- operates with the addition of only one or two electrons. That capability would make the transistor important to a range of computational applications, from ultradense memories to quantum processors, powerful devices that promise to solve problems so complex that all of the world's computers working together for billions of years could not crack them.

In addition, the tiny central island could be used as an artificial atom for developing new classes of artificial electronic materials, such as exotic superconductors with properties not found in natural materials, explained lead researcher Jeremy Levy, a professor of physics and astronomy in Pitt's School of Arts and Sciences. Levy worked with lead author and Pitt physics and astronomy graduate student Guanglei Cheng, as well as with Pitt physics and astronomy researchers Feng Bi, Daniela Bogorin, and Cheng Cen. The Pitt researchers worked with a team from the University of Wisconsin at Madison led by materials science and engineering professor Chang-Beom Eom, including research associates Chung Wun Bark, Jae-Wan Park, and Chad Folkman. Also part of the team were Gilberto Medeiros-Ribeiro, of HP Labs, and Pablo F. Siles, a doctoral student at the State University of Campinas in Brazil.

Levy and his colleagues named their device SketchSET, or sketch-based single-electron transistor, after a technique developed in Levy's lab in 2008 that works like a microscopic Etch A SketchTM, the drawing toy that inspired the idea. Using the sharp conducting probe of an atomic force microscope, Levy can create such electronic devices as wires and transistors of nanometer dimensions at the interface of a crystal of strontium titanate and a 1.2 nanometer thick layer of lanthanum aluminate. The electronic devices can then be erased and the interface used anew.

The SketchSET -- which is the first single-electron transistor made entirely of oxide-based materials -- consists of an island formation that can house up to two electrons. The number of electrons on the island -- which can be only zero, one, or two -- results in distinct conductive properties. Wires extending from the transistor carry additional electrons across the island.

One virtue of a single-electron transistor is its extreme sensitivity to an electric charge, Levy explained. Another property of these oxide materials is ferroelectricity, which allows the transistor to act as a solid-state memory. The ferroelectric state can, in the absence of external power, control the number of electrons on the island, which in turn can be used to represent the 1 or 0 state of a memory element. A computer memory based on this property would be able to retain information even when the processor itself is powered down, Levy said. The ferroelectric state also is expected to be sensitive to small pressure changes at nanometer scales, making this device potentially useful as a nanoscale charge and force sensor.

The research in Nature Nanotechnology also was supported in part by grants from the U.S. Defense Advanced Research Projects Agency (DARPA), the U.S. Army Research Office, the National Science Foundation, and the Fine Foundation.

China Rebuilds Its Power Grid as Part of Its Clean Technologies Push
By COCO LIU of ClimateWire
Published: April 20, 2011

SHANGHAI -- As the world's largest fossil fuel consumer, China is trying to use more clean energy, but it has a major handicap to overcome: Its current electric grid can't handle it.

State Grid Corp. of China, the country's top electricity distributor, hopes to get around this impasse by building what it calls a "strong, smart grid." After two years of testing its grid plan, the company is now throttling up to full-speed implementation.

The hope is to rescue renewable energy, especially wind power, from a technical bottleneck. Additionally, a smarter power grid would create demand that could give China a better position in the lucrative and highly competitive global smart grid component manufacturing race. Finally, it would also help reduce the nation's transportation emissions by developing a nationwide electric vehicle charging network.s

Since Chinese leaders have yet to regulate this nascent sector, it is State Grid that will make the decisions for national grid development. The result of its ongoing grid plan will not only affect its more than 1 billion customers in China, but also be felt by the outside world.

The overarching goal for the more advanced transmission network, according to the company, is to reduce enough carbon emissions to help China achieve at least 20 percent of its targeted emission cuts.

China's emission cuts have never been more important to the success of combating global warming. With its population of 1.3 billion and its energy-guzzling manufacturing industry, China now consumes more energy than any other nation, accounting for more than a fifth of the world's energy-related greenhouse gas emissions.

Hooking up stranded wind power

For the sake of its environment and energy security, China in recent years has been trying to add renewable energy into its power mix, but the country's strongest winds, brightest sunlight and most powerful rivers aren't found near the nation's energy-hungry regions. That poses a challenge to transmitting electricity generated from renewable sources, with wind power being the prime example.

Rajesh Panjwani, who heads power research at Hong Kong-based investment firm CLSA, noted that the development of Chinese grids has failed to keep pace with the rapid growth of China's wind farms. Thus, at the end of 2009, about one-third of installed wind turbines in China were unable to get connected to the grid.

And for those lucky ones that are connected, they often have to be shut down when wind is at its peak because the existing grid is too weak to handle the unpredictable off-and-on nature of wind power surges.

That has been causing a huge energy waste. In the first half of 2010 alone, wind-generated electricity that could have been used by about 10 million Chinese for a whole year had nowhere to go, according to the latest government figures.

State Grid wants to remove that bottleneck. Its strategy is to adopt ultra-high-voltage power lines that can carry heavy flows of electricity across the vast country. Such network -- nonexistent in 2008 -- would stretch across China as a lifeline for absorbing wind power.

By 2015, the company declared, its grid infrastructure would be in line with growth in the nation's wind power sector. China last year surpassed the United States to become the world's No. 1 in wind power generating capacity, and this capacity is scheduled to more than double in the next five years.

Clean power to Shanghai and greener power for cars

Meanwhile, more solar and hydro power would be able to flow into the grid. Already, through State Grid's recently built pilot project, electricity generated from hydro power is being sent over a thousand miles to Shanghai, allowing it to style itself as the biggest clean energy-consuming city on Earth.

In addition, technology innovation is under way to make the grid smarter. This year, State Grid began cooperating with the Asian Development Bank to research wind forecasting, with the hope of someday being able to make better use of intermittent wind power, said Yang Hongliang, who leads this cooperative project at the Asian Development Bank.

Moreover, the grid development is also expected to forge Chinese manufacturing power, as was in the case of a clean energy sector in which China now leads the world.

Driven by strong domestic demand, China's wind turbine industry -- which barely existed in 2004 -- now holds four seats among the world's top 10 manufacturers. And local maker Sinovel, which got its start with imported technology, later used its own invention to develop the first major offshore wind farm outside Europe.

Just like wind turbine makers, "the development of the grid in China will nourish Chinese smart grid component makers, preparing them for future global competition," said Peng Ximing, an energy specialist from the World Bank in Beijing.

China's grid upgrade will also help boost the nation's green car sector. Over the next five years, hundreds of thousands of electric vehicles charging points will be added as part of the grid plan, in order to help State Grid position itself in a much-anticipated market.

In return, that will encourage Chinese automakers to produce electric cars and pave the way for drivers who want to switch, said John Zeng, auto analyst at global marketing firm J.D. Power and Associates. Until now, Zeng added, electric car demand has been stifled partly because of a lack of charging stations.

Can China's grid become a two-way street?

Still, some problems remain unsolved in State Grid's master plan. The initiative is especially upsetting providers of one emerging clean energy solution that allows consumers to generate their own electricity and recycle energy waste to meet heating and cooling needs.

Feng Jianghua, who represents the natural gas distributed power generator industry at the China Gas Association, pointed out that the advanced grid plan lacks specifics on how it will resolve a major problem that is preventing consumers from embracing the industry's low-carbon energy solution.

According to Feng, switching to such a solution requires the grid connection as backup, but grid companies are reluctant to integrate power systems installed by consumers, claiming technical barriers and conflicts of interest.

"Rising distributed generators use means declining sales for grid companies," Feng said, adding that consumers that want to switch are usually energy-intensive factories, office buildings and shopping malls that are considered as VIPs for grid companies.

But this conflict could see an end within the next five years. Peng of the World Bank noted that the government here is now drawing national grid connection standards, which include addressing grid constraints on the growth of distributed clean energy.

"Rocket to go to moon under design
By Xin Dingding (China Daily)
Updated: 2010-03-05 07:26

BEIJING: A new heavy-thrust carrier rocket is under scientific research, with the goal of sending astronauts to the moon, scientists said.

8gc0i.jpg

A model of the Long March V rocket

Although there is no official timetable yet for China's moon landing, scientists are researching a new powerful carrier rocket with a lift-off thrust of 3,000 tons, Liang Xiaohong, vice-president of the China Academy of Launch Vehicle Technology, told China Daily on Thursday.

"The heavy-thrust launcher's lift-off thrust will be three times that of the Long March-5
, China's current largest launcher," said Liang, who is also a member of the 11th CPPCC national committee.

The large-thrust Long March-5 launch vehicle has a lift-off thrust of 1,000 tons, which enables it to send a maximum payload of 25 tons to the near-Earth orbit and a payload of 10 tons to the higher geo-stationary orbit. Designed for transporting heavyweight satellites and space stations, it is slated to take off in 2014, according to Liang.

Compared to the Long March-5, the heavy-thrust launcher will be more powerful, but its payload capacity is still under discussion, he said.

The Long March-5 is also likely to be used in the preparatory stage of a future moon landing, he added.

China is currently studying the feasibility of a moon landing, despite US President Barack Obama's decision to kill NASA's $100-billion plans to return astronauts to the moon.

Bao Weimin, an academician with the Chinese Academy of Sciences and a CPPCC national committee member, said: "A moon landing program is very necessary, because it could drive the country's scientific and technological development."

Besides the heavy-thrust carrier rocket under study, the academy is also developing a new family of carrier rockets for future space programs.

"The Long March-6 will be a small-thrust carrier rocket, and the Long March-7 will be a medium-thrust launch vehicle. Together with the Long March-5, they will form a family that can cover all necessities for launch vehicles and replace the current carrier rockets," Liang said.

So far, the Long March-5 project has entered the testability analysis stage, he added.

About 100,000 square meters of workshops have been completed so far at a new base being built in the Binhai New Area of the northern coastal city of Tianjin. The facility will be used for testing and manufacturing the Long March-5. Construction began last year with an investment of 1.5 billion yuan ($220 million), Liang said.

Eventually, a total investment of 10 billion yuan will be poured into the base, which will be able to produce a maximum of 12 Long March-5 launch vehicles each year, he said.

Qi Faren, former chief designer of Shenzhou spaceships and a CPPCC national committee member, said on Thursday that the Long March-5 will be used to launch China's space station mission.

"We aim to send the core module of the space station into orbit before 2020. Without the large-thrust launcher, the 20-ton core module cannot be in place," he said.


Before that, however, the first task of the Long March 5 may be to send the Fengyun-4 weather satellite into space from the launch center under construction at Wenchang in Hainan, China's southern island province, according to Liang.

The new Fengyun-4 satellite, which is under design, weighs about eight to nine tons, which cannot be lifted by the current launchers that can carry a maximum payload of 5.2 tons to geo-stationary orbit, he added.
