The Earliest Flowers in the World
The Chinese Ancient Fruit named for a flower blossomed as early as 145 million years ago was recently found in Liaoning, China, and confirmed by experts the most ancient angiosperm (flower bearing) plants so far discovered in the world.
The discovery makes a new breakthrough in the studies of the origins and early evolutions of angiosperm plants in the world and its finding was published as a cover page story by the U.S. journal: 《Science》.
The investigation team headed by Prof. Sun Ge with Jilin University unearthed ancient fossils of the Chinese Ancient Fruit over Beipiao area in the western region of Liaoning in 1998. Later in 2000 Prof. Sun Ge together with Ji Qiang of the Chinese Academy of Geology discovered the same fruit fossils in the same geological period over Lingyuan area of the same region. Scientists have classified the extinct ancient angiosperm as a new branch in the family - ancient fruit section.
Visual Chinese Man
Prof. Tian Jie, Director of Artificial Intelligence Lab, Institute of Automation under the Chinese Academy of Sciences revealed on April 23, 2002 that Chinese scientists have proposed the so-called Visual Chinese Man Program aiming at raising China's overall medical level and promoting the information process and modernization of Chinese traditional medicine.
The visual human body technology is able to mix modern computer and information technology into traditional medical sciences by utilizing digital human body information collected from real man, creating visual man through computer based simulation technology and making diagnosis and treatment studies that cannot be done on real man possible. Visual man techniques may also help to turn property oriented examination into the quantity based one so as to make clinic diagnosis and treatment more objective, seeable and accurate. As they are derived from real man, the data are able to represent different characteristics of different nationalities and regions.
Prof. Tian expresses that once it is approved, the project will fill in a blank in the country. By that time, Chinese scientists will collect representative data on Chinese human species.
Jointly proposed by the Chinese Academy of Sciences, Tsinghua University and Peking University, Visual Chinese Man Program has seen the completion of its preparation and it will take half a year or one year to complete the data collection.
