VanRooy, Wilhelmina; Sultana, Khalida – Teaching Science, 2010
This article describes a simple, inexpensive, easy to conduct gel-electrophoresis activity using food dyes. It is an alternative to the more expensive counterparts which require agarose gel, DNA samples, purchased chamber and Tris-borate-EDTA buffer. We suggest some learning activities for senior biology students along with comments on several…

Leang, K. K.; Zou, Q.; Pannozzo, G. – IEEE Transactions on Education, 2010
Piezoelectric actuators (or piezoactuators) are known for their nanoresolution and high-speed positioning capabilities. Therefore, they are used in scanning probe microscopes and in the design of innovative surgical tools and biomedical devices. The expected growth of engineering jobs in the nano- and bio-related fields, in which piezoactuators…

Bottomley, Steven; Chandler, David; Morgan, Eleanor; Helmerhorst, Erik – Biochemistry and Molecular Biology Education, 2006
A new computer-based molecular visualization tool has been developed for teaching, and learning, molecular structure. This java-based jmol Amalgamated Molecular Visualization Learning Environment (jAMVLE) is platform-independent, integrated, and interactive. It has an overall graphical user interface that is intuitive and easy to use. The…
