Structural Evolution of the Protein Kinase-Like Superfamily
The protein kinase family is large and important, but it is only one family in a larger superfamily of homologous kinases that phosphorylate a variety of substrates and play important roles in all three superkingdoms of life. We used a carefully constructed structural alignment of selected kinases as the basis for a study of the structural evolution of the protein kinase-like superfamily. The comparison of structures revealed a “universal core” domain consisting only of regions required for

The Scientific Method: An Introduction Using Reaction Time
Reaction time has many advantages for the introduction of the scientific method--the subject is familiar, many experiments are possible, and students enjoy competition. In our Introductory Biology courses, our students formulate and test a hypothesis about reaction time. We use Kosinski's Reaction Time software, that records reaction times and then analyzes them statistically using the chi-square median test. Students then write a paper that either rejects or fails to reject their null hypothesi

3.1 Thinking about intervention

So far we have looked at issues relating to how we define ‘abnormal’ behaviour, and how we think about explanations. Now we will consider the more practical issue of how to approach the treatment of such difficulties. As in the previous section, we will discuss behavioural, cognitive and biological perspectives on treatment and consider specific techniques from each perspective that are applicable to the management of dyslexia.

Episode 143: Radiation for the rest of us: The alpha, beta and gamma of atomic interaction

Physicist Dr Roger Rassool discusses the basic physics behind the radioactivity produced -- and sometimes leaked -- in the production of nuclear power. With science host Dr Shane Huntington.
