<jats:title>From single molecules to embryos in living color</jats:title> <jats:p> Animation defines life, and the three-dimensional (3D) imaging of dynamic biological processes occurring within living specimens is essential to understand life. However, in vivo imaging, especially in 3D, involves inevitable tradeoffs of resolution, speed, and phototoxicity. Chen <jats:italic>et al.</jats:italic> describe a microscope that can address these concerns. They used a class of nondiffracting beams, known as 2D optical lattices, which spread the excitation energy across the entire field of view while simultaneously eliminating out-of-focus excitation. Lattice light sheets increase the speed of image acquisition and reduce phototoxicity, which expands the range of biological problems that can be investigated. The authors illustrate the power of their approach using 20 distinct biological systems ranging from single-molecule binding kinetics to cell migration and division, immunology, and embryonic development. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.1257998">10.1126/science.1257998</jats:related-article> </jats:p>

<jats:p>China's expansion of universities has not been on a level playing field. Earlier this year, Education Minister Guiren Yuan declared that the government must treat both public and private universities equally. As founder and president of one of China's largest private universities, I wholeheartedly agree. China's private universities can help usher in new opportunities for social and economic development, but they must be enabled to launch robust education programs and compete for research grants. Unless the government loosens restrictions on such endeavors, private universities could enter a tailspin, and such an erosion of higher education could threaten social stability.</jats:p>
