Mating preference in the commercially imported bumblebee species Bombus terrestris in Britain (Hymen
Commercial trade of bumblebees in Europe results in different subspecies of Bombus terrestris being shipped into regions where they are not native. Although previous studies have shown that these subspecies will interbreed, none have assessed mating preference of the different populations. This study examines the mating preferences between two geographically isolated populations of B. terrestris which have unnaturally been brought together through the commercial trade in bumblebees. Under contr
This Flash based applet simulates data from a case study of treatments for tumor growth in mice. This simulation allows the user to place mice into a control and treatment groups.
Sea Urchin Development
This article describes set-up and maintenance of marine aquaria for maintaining sea urchins and procedures for the study of developmental biology of sea urchins from fertilization to pluteus larva.
The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome. This
Using Bromelain in Pineapple Juice to Investigate Enzyme Function
This investigation introduces students to the structure and function of the proteolytic enzyme, bromelain, which is present in large quantities in the fruit, leaves, and stems of pineapple. In this lab exercise, students study the rate at which bromelain catalyzes the hydrolysis of gelatin (substrate) at different temperatures and pHs. Strips of developed black and white photographic film are placed in freshly squeezed pineapple juice under different experimental conditions. The time it takes fo
Using Handheld Wireless Computers to Increase Interactivity and Collaborative Learning in Large Clas
We conducted a pilot study to determine the effectiveness of wireless, handheld computers in fostering active and collaborative learning in lecture-based teaching. We compared the capabilities of the largest type of handheld, the Jornada 820, to that of the smallest, a Handspring Visor "personal digital assistant." This article describes our use of the handhelds in a variety of classroom exercises, emphasizing wireless internet access. We explain our successes, problems, and proposed solutions.

Bio Viz: Congo River
Our innovative Science Bulletins include interactive data visualizations that offer a satellite's-eye view of changes in the biosphere. Published in June 2006, this Bio Viz takes a look at one way land cover maps are helping scientists study fish species.
Sam Tanenhaus; Bill Fletcher and Michael Zweig
Digging deep into the roots and evolution of the American conservative movement, Sam Tanenhaus talks with Bill Moyers about why he believes that conservatism is dead and how it might yet come back to life. Tanenhaus is the editor of both THE NEW YORK TIMES BOOK REVIEW and the Week in Review section of the TIMES. And, with public support for labor unions at its lowest point in 70 years, Bill Moyers talks with experts Bill Fletcher, co-author of SOlIDARITY DIVIDED: THE CRISIS IN ORGANIZED lABOR AN
The anatomy cookbook: A dissection guide with recipes
The Anatomy Cookbook has been written to accompany an anatomy and physiology course for bioengineers who would otherwise have missed out on the opportunity to study real organ systems at first hand. It is not an alternative to a standard anatomy text, it acts more as a laboratory supplement. The fun bit is that your kitchen takes the place of the dissection room. Each recipe provides an insight into one or more organs, and all you need to do is go to the supermarket and be prepared to think abou

In Conversation: Semiconductor
Featured in Black Box in 2008, Brighton-based duo Ruth Jarman and Joe Gerhardt, a.k.a. Semiconductor, have returned to Washington. A Smithsonian Artist Research Fellowship at the National Museum of Natural History allowed them to research volcanic activity. They discuss their current project, an installation based on their study of live volcanoes in the Galapagos Islands and Ecuador.
