    Several strong earthquakes with magnitude 7 up struck China in recent years, causing tremendous losses of life and property. The research of earthquake mechanism and seismic activity has been paid much attention now. Traditional ideas are that an earthquake occurs when it reaches the critical state of stress, after a long period of preparation. Therefore, it seems that as long as there are fully observation and research, we can determine the location, time and magnitude of an earthquake. But it is often not so optimistic under the real condition of an earthquake. In recent years, some of the observed facts show that small earthquakes in some areas can be triggered by surface waves of strong earthquakes in the distance. Laboratory studies show that small normal perturbation could change the original law of fault unstable sliding. These facts indicate that there is a certain degree of uncertainty in the occurrence of earthquakes.

    Graphene — the limiting form of graphite, with a twodimensional crystalline structure of single atomic layer, was first obtained in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester. In 2010, the Nobel Prize in Physics was awarded to them “for groundbreaking experiments regarding the twodimensional material graphene”. Starting from the history of carbon materials, this review summarizes recent developments in structural properties，characterizations and preparation of graphene. Future trends and challenges in graphene research are discussed.

    On Oct 6th, 2010, the Royal Swedish Academy of Sciences announced that the Nobel Prize in chemistry for 2010 was awarded jointly to an American scientist Richard F. Heck and two Japanese scientists Eiichi Negishi and Akira Suzuki for their great contributions to palladiumcatalyzed crosscoupling. It provides one of the most sophisticated tools available to chemists to create complicated organic molecules. This tool has been widely used in pharmaceuticals, electronics industry, and advanced materials. A brief introduction for palladiumcatalyzed crosscoupling was presented in this paper.

    The 2010 Nobel Prize in Physiology or Medicine was awarded to Robert G. Edwards, regarded as “the father of Test Tube Baby”. The Test Tube Baby, known as a marvelous assisted reproductive technology, has brought significant influence into human society. Test Tube Baby was a technique merging in vitro fertilization and embryo transfer to help the infertile couples have descendants. The intracytoplasmic sperm injection (ICSI) and preimplantation genetic diagnosis (PGD) were the development and extension result of Test Tube Baby. In this essay, a brief introduction to the history，application and ethical issues of Test Tube Baby were given.

    Humaninduced global changes (e.g. land use/land cover changes, climate change, elevated atmospheric CO2, atmospheric nitrogen deposition) have brought about several variations in the traits, interspecies relationship, species distribution, and biodiversity of biological organism. And further, as the biological organism is the main body of ecosystem, the changes have already had an impact on the ecosystem process and function, and consequently our human survival and social sustainable development. We have combined global change experiments with environmental gradient methods to study the response and acclimation of major forest ecosystems and grassland ecosystems to global change in china. And we had already achieved some initial results. In view of the carriedout experiments and the obtained results, combined with our unique natural conditions, we should take a coordinated approach for future research in this dynamic field: ①stable and increased support for longterm multifactor experiments; ②explicit inclusion of climatic suitability module, habitat availability/suitability module, population dynamics module and dispersal module in a dynamic specie distribution model; ③better integration amongst experimentals, monitoring, and models by building a datamodel fusion system; ④assessment for the ecosystem response and acclimation to global and regional changes using a hierarchical modeling.

    Using reclaimed water perform groundwater recharge is a costeffective method to alleviated groundwater resource depletion problems caused by excessive extraction. The reclaimed water reuse status quo in China was described and the current international research development trends and progress about reclaimed water infiltration recharge were summarized. Combining our country actual situation, the authors point out that the research on reclaimed water reuse through groundwater recharge is an important new research direction in the field of surfacesoilgroundwater resources transformation, which has obvious characteristics of multiinterdisciplinary. Strengthen researches in this area have great practical significance for promoting safe reuse of reclaimed water in our country.

    Discovery can be made by studying the concept of time and space in the theory of Rongjie state which is based on information, that time is a sort of measure for the movement from initiation to termination and is a spatial concept which is continuously incremental with the movement and cannot flow backwards. Substance space is in motion, moving for expansion or contraction only in a straight line (or radial direction); Time and space does not exist in one form. Time is not the higher one within the threedimensional material space. Characteristics of unity and change about singulars in photons not only determines the speed of light, but also determines that the energy of matter can only make the movement of substance reach the speed of light. However, as particles in photon absorb information and completely turn into particles of information, its speed will be far more than the speed of light; the effect energy moving in the speed of information energy can make the movement of material faster the light speed. Conclusion: humans can not pass through time and space to reach the future or the past, but can catch the information images of passed things by flying beyond the speed of light.

    Ten years ago, the International Human Genome Project spent 3 billion dollars for more than a decade to complete the initial draft of the human genome. It was reasonable to consider that the scientists can draw the Map of Life and the life science stepped into postgenome era. In the first postgenome decade, on the one hand, the success of HGP have generated huge advance in biology science; on the other hand, the genomic medicine was not developed and the critics argued that genomics industry was a “genomics bubble”. Looking back over the past decade of human genomics, a retrospective review on developments and challenges of modern life science maybe promise insight into life science in postgenomic era.
