Here is an image taken under fluorescence microscope, with DAPI staining (Blue) showing the nuclei of each BPH1 cell. BPH1 is a human benign prostatic hyperplasia cell line which is close to human normal prostate epithelia cell. A marker of epithelial cells, E-cadherin (Red) was detected in the cell membrane between cell-cell contacts. When membrane targeted PTK6 was expressed in BPH1 cells, it induced the formation of peripheral adhesion complexes (Green, visualized by phospho-tyrosine staining) around cell membrane. Interestingly, these “green” cells showed a remarkable loss of E-cadherin (Red). This phenomenon is called epithelial-mesenchymal transition (EMT) in biological terms, which is an important factor in human tumor progression. In other words, red cells represents normal cells and green cells represents tumor-like cells; membrane targeted PTK6 induces normal prostate cells to become tumor-like cells.

The STEM makes it possible to observe the nano materials at atomic resolution, with the image contrast correlates with the material atomic number. The electron energy loss spectroscopy (EELS) combined with STEM could provide us the chemical information by mapping the elemental distribution of the nano-catalyst. All the information obtained by STEM is important for understanding the function of the Co-based FT catalyst, which could be a solution to the potential energy crisis. As can be seen in the image, a particle of 10 nm in diameter sits on a chunk of support. The later chemical analysis by EELS shows that it is a Co particle covered with a Mn shell sitting on the Ti support. One facet of the particle is hexagonal. The bright spots on the hexagonal facet are the atomic columns. The clear observation of the atomic columns demonstrates the powerful magnification function of the STEM. By using the STEM, the landscape of the nano-world is always amazing."

This is the case of the Los Tuxtlas forest in Veracruz, Mexico where almost 87% of the original forest area has been lost. Remaining remnants persist as archipelagoes of often very small forest fragments. My research tests how forest fragmentation affects plant species dynamics by studying Poulsenia armata (Moraceae), a widespread tropical tree. This photograph was taken as part of my long-term study in order to assess the role that small mammals have on this tree species. It is believed that small mammals could be experiencing less competition in the forest fragments, therefore increasing seed predation and affecting the persistence of the plant species that they eat. The picture shows an arboreal mammal (Tylomys nudicaudus) that is very rare in this region. The presence of this small mammal is significant to my study because it not only illustrates the possible seed predators of the Moraceae tree species, but also indicates the role of the remaining fauna in the fragmented forest."

My goal is to paint these ordinary objects lovingly and to, in a way, defend them. Seeing is never neutral, but always involves a process of interpretation that occurs within existing social and political context. By focusing on the ordinary, it is possible to arrive at an understanding of the dynamic forces that give meaning to individual lives and that are both the obstacle and the vehicle to achieving lasting social change.
