Small Regulatory RNAs May Sharpen Spatial Expression Patterns
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis, others ar

Plants That Aren't Plants: Mosses and Lichens
Mosses and lichens are not given much attention in introductory biology laboratory courses, in part because instructors lack skills necessary to cover the topic-namely, moss leaf cross sectioning and lichen chemical spot tests. Acquiring confidence in just these two techniques, as well as familiarity with basic terminology, lays a foundation for further investigation.

Wireless Sensor Networks for Ecology
Field biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to "observe the unobservable" through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals -- even multiple times per second -- over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively

Living and non-living things
Living things often rely on non-living things to accomplish daily tasks. Living things have several characteristics that non-living things do not, such as the ability to move, eat, breathe, and reproduce. Living things and non-living things can interact even though they do not have the same characteristics.

Tissue movement in bipopulation tumour cord growth
Simulation of tumor cord growth where conversion of the tumor to glycolytic (anaerobic) metabolism takes place under hypoxia. This video shows volume fraction of glycolytic cell population and velocity of tissue movement. Isolines show hypoxia limits for aerobic and anaerobic cell lines respectively. This video reflects work in progress and may be different from the final results.

Business Information Systems: Design an App for That
Students in introductory Management Information Systems (MIS) courses often ask what a career in MIS looks like. Lacking a clear vision, they make their own assumptions. Often they assume the career involves programming with little human interaction. That MIS is a technical field could not be further from the truth. MIS job descriptions typically require candidates to be able to collaborate, communicate, analyze needs and gather requirements. They also list the need for excellent written and com
