Next-generation sequencing (NGS)-based methods are revolutionizing biology. Their prevalence requires biologists to be increasingly knowledgeable about computational methods to manage the enormous scale of data. As such, early introduction to NGS analysis and conceptual connection to wet-lab experiments is crucial for training young scientists.…

Proteins are a diverse class of biochemical macromolecules, including substances as (apparently) unrelated as silk and sinew, hair and horn, feathers and flagella, enzymes and epidermis, gelatine (jelly) and gluten and gore, spider web, meat and fish muscle. Yet they are unified by being polymers of amino acids. Discovery of the nature of proteins…

Although an understanding of radiometric dating is central to the preparation of every geologist, many students struggle with the concepts and mathematics of radioactive decay. Physical demonstrations and hands-on experiments can be used to good effect in addressing this teaching conundrum. Water, heat, and electrons all move or flow in response…
