According to xinhua news agency, Tokyo on January 23 report (reporter LanJianZhong) Japanese researchers found some decided to plant blade shape genes, the discovery may applied in gardening or development taste different vegetables.
Kyoto university in plant molecular biology experts hill led know east-zhejiang research group, analyzes cruciferous plant arabidopisis thaliana "TCP" genetic group effect, found plants with this genetic group.
Researchers found that in this genetic group 24 gene, if let more genes not play a role, leaf margins drape becomes more deep and become dentate.
Conversely, if let genetic group in more genes active, leaf margins of jagged part becomes smooth. In addition, if overly strengthen or inhibit "TCP" genetic group role, will have an adverse impact.
According to xinhua news agency, Stockholm electricity (newsman ChenXueFei) Swedish capital Stockholm grand central station using heat exchange system collection station near the office building for its waste heat energy-saving 25%. Year heating, This project environment department manager klaas-jan · johansson 19 in an interview with xinhua newsman telephone introduced their achievements.
Johansson said, the central station every day approximately 25 million passengers dealings, there are very many coffee shops and stores, etc, can produce a lot of heat.
