چکیده
One never forgets the sheer excitement of an infant's first hesitant steps; the clumsy but undaunted efforts that you know will soon develop to the confident strides that will enable entry to the 'real world'. It is hard to avoid similar thoughts when one looks at the steps currently taken to achieve movement at the nanoscale. In a nano-world where thermal Brownian motion rules, finding movement is trivial but the question of control is not1, 2. It is particularly challenging to fuel molecules and nano-objects to induce directional translational and rotary motion3, 4, 5. Major leaps are certainly still necessary, but ultimately the design of molecular motors will enable the construction of nano-machinery and nano-robots and hold promise for applications as broad as sensing, drug delivery and out-of-equilibrium assembly systems.

Enhancing Students' NOS Views and Science Knowledge Using Facebook-based Scientific News
This study investigated how the different discussion approaches in Facebook influenced students’ scientific knowledge acquisition and the nature of science (NOS) views. Two eighthand two ninth-grade classes in a Taiwanese junior high school participated in the study. In two of the classes students engaged in synchronous discussion, and in the other two classes they engaged in asynchronous discu...
متن کاملNatural product synthesis: clearing the way to cortistatins.
The determination of molecular structure is an important step in the potential applications of naturally occurring organic compounds with interesting biological activity. For a significant fraction of newly isolated natural products, however, standard analytical techniques such as Nmr and mass spectrometry cannot provide a definitive structure. Now, Leo gross and co-workers have used a scanning...
