Large Cassava Plants May Reduce Hunger in Africa
The genetically modified cassava plants developed by Ohio State University molecular biologist Richard Sayre could help solve food shortages in Africa and other nations. His study reports that his genetically modified cassava plants produced roots that were an average of 2.6 times larger than those produced by regular plants. Sayre used a gene from the bacterium E. coli to genetically modify normal cassava plants. Cassava is the primary food source for more than 250 million Africans - about 40 percent of the continent's population, and the plant's starchy tuberous root is an important foodstuff for nearly 600 million people worldwide. Sayre said he hopes to offer these plants to countries where cassava is a significant part of the diet. The researchers used a variety of cassava native to Colombia. They inserted into three cassava plants an E. coli gene that controls starch production. According to Sayre's research Cassava actually has this same gene, but the bacterial version of the gene is about a hundred times more active. Consequently, the modified plants converted more of their sugar into starch, as shown by an increase in root size as well as the number of roots and leaves produced by each modified plant. The results of the research showed that the roots of the modified plants were up to 2.6 times larger than the roots of a non-modified plant and produced a third more leaves - a maximum of 123 leaves per modified plant vs. 92 leaves per non-modified plant. "Not only did these plants produce larger roots, but the whole plant was bigger and had more leaves," Sayre explained, adding that both the roots and leaves of the cassava plant are edible.

Early Earthquake Warning System Developed in Japan
It may now be possible to warn people of an earthquake before the most destructive tremors strike. The Japan Meteorological Agency (JMA) plans to provide emergency quake information directly to railway operators, fire departments, and other key institutions. When earthquakes occur, preliminary tremors called primary waves are detected first. These occur at high speeds and are followed by the slower and bigger main tremors, called secondary waves. In the Emergency Earthquake Warning system, the difference in the speeds of the two types of waves is analyzed to estimate the time the secondary waves will arrive and their intensity before the main tremors take place. This information is then immediately announced. Researchers at the JMA think they can use the technology to create a home warning system as well, which would reduce earthquake damage by quickly and automatically shutting off gas and electricity supplies. Furthermore, such a system could give household members precious seconds to shelter themselves in a safe place, such as under a table. For details, please see http://snipurl.com/tygh.

Market Drives New Solar Technology
The booming solar-cell industry is driving investment in newer technologies that could make solar power as cheap as electricity from the grid. Indeed, demand for solar power due to rising energy prices, supportive government policies, and a solar industry suddenly with enough revenue to support new marketing campaigns, has outpaced the ability of manufacturers to produce conventional crystalline silicon solar cells. It is believed that demand for solar power at current prices is around double the expected production capacity this year. In order to cope with the demand, at least 50 companies are developing unconventional solar cell technologies, most of which are planning pretty significant expansions of production. These initiatives are based on second-generation solar technologies, many of which were discovered decades ago, but have taken years to develop to the point where they can convert light into electricity efficiently and be manufactured reliably. Dye-sensitized solar cells, non-crystalline silicon cells, cells based on organic materials, and thin-film solar cells using inorganic semiconductors made of elements such as cadmium and tellurium or, in the case of Nanosolar and many others, copper, indium, gallium, and selenium (CIGS) are some of the examples. However, despite the fact that the new technologies are expected to be cheaper than conventional solar cells, crystalline silicon will not disappear anytime soon. Moreover, third-generation solar technology will be designed to breakthrough a major problem with today's new technologies, which, although are cheaper and easier to make than crystalline silicon cells, are not much more efficient at converting sunlight to electricity (Source: http://snipurl.com/tygj).

Low Representation of Women in S&T
Women are persistently under-represented in the science and technology (S&T) enterprise that greatly hindrances to strengthening science capacity worldwide. The new report by the Inter-Academy Council (IAC), an organization created by 90 science academies across the globe, stressed the need for immediate action to help overcome this situation. In its advisory report Women for Science, the IAC revealed that only 5 percent of the academy's members are women, and many research institutions in the world are not fully opening their doors for women scientists resulting in significant drop of young women scientists in S&T careers compared to men. The report advocates for commitment to the full inclusion of women in all scientific organizations. The report concludes that various measures, such as commitment from the top leadership, clear criteria for promotions and awards, professional training and mentoring, and inclusion of women in formal and informal organizational networks should be undertaken to attain this goal.

UN Launches Global Alliance for ICT
The United Nations Deputy Secretary-General and Malaysia's Prime Minister launched the Global Alliance for Information and Communication Technologies (ICT) and Development at a meeting in Kuala Lumpur, on June 19th. Prime Minister Abdullah Ahmad Badawi said that the Alliance recognized ICT as a vital tool for development and he hoped that with the lead given by the United Nations to this Alliance it would possible to see more widespread applications of ICT where poorer nations will benefit through greater access to technology and to knowledge. The Alliance's Strategy Council also met for the first time. The 60 members of the Council, from the fields of ICT, development, public policy, education, health and other spheres, will establish priorities for the Alliance's work. After two days of meetings, involving over 700 experts from around the world, the Alliance has established a framework for their activities. Pledging to overcome the social and digital divides between developed and developing world, the Vision promotes policies and partnerships that can help create an "arc of digital opportunity."
