An apple
Objects appear to be certain colors because of reflection and absorbance. Light is made up of different wavelengths that our eyes detect and convert into colors. The apple looks green because it reflects the wavelengths that correspond to the color we see as green. The apple absorbs all other wavelengths of light.

"Quasi-Balanced Circulations in Oceans and Atmospheres, Fall 2009"
" This course introduces the students to dynamics of large-scale circulations in oceans and atmospheres. Basic concepts include mass and momentum conservation, hydrostatic and geostrophic balance, and pressure and other vertical coordinates. It covers the topics of fundamental conservation and balance principles for large-scale flow, generation and dissipation of quasi-balanced eddies, as well as equilibrated quasi-balanced systems. Examples of oceanic and atmospheric quasi-balanced flows, compu

Saturday Night on the Range: Rural Life in World War I Era Montana
We often like to imagine rural life in the past as timeless, "traditional," and in some way simpler and more authentic. Yet, rural life in the years around World War I, while sometimes recalled as simpler, could often seem very much like life anywhere else. In this interview, conducted by Laurie Mercier in 1982 for the Montana Historical Society, Tom Staff remembers how Montana farmers took other jobs to supplement their incomes. Here he described how the road crew he worked on left camp for dan

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

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.
