This index organizes teaching resources by topic-related issue and provides teaching resources (case studies, problems, videos, articles, activities, and other resources) which can be used to to facilitate the teaching of introductory non-majors biology using Problem or Case Studies Based Learning.

At Fred Hutch, we support engaging, challenging and relevant classroom learning experiences for all students by providing access to high-quality instructional materials developed by teachers and scientists. Our free, open-source lessons and units are geared towards high school biotech and biology teachers and focus on giving students opportunities to explore biotechnology and the social dimensions of research science.

Bowhead whales (Balaena mysticetus), denizens of Arctic seas, are known to live more than 200 years, yet they show few signs of the age-related ailments that plague other animals, including humans. Even the bowhead's closest cetacean relative, the much smaller minke whale, lives only 50 years. That suggests the larger whales (which have more than 1000 times as many cells as humans) have evolved some special natural mechanisms that protect them against cancer and aging.

Life on Earth is intimately connected to the natural cycles of light and dark that make up a 24-hour day. For plants, animals, and even bacteria, these circadian rhythms control many biological functions. Humans can overrule their body clocks, but at a price: People whose circadian rhythms are regularly disrupted-by frequent jet lag or shift work, for example-are more vulnerable to diabetes, obesity, cardiovascular disease, and cancer. There are various theories to explain these associations, and researchers now have a new player to consider: the bacteria that live in the digestive tract. According to a study in mice and a small group of human volunteers, the internal clocks of these gut microbes sync up with the clocks of their hosts. When our circadian rhythms get out of whack, so do those of our bacteria.

Call it a scientific oddity-or a medical miracle. A girl who grew up with a serious genetic immune disease was apparently cured in her 30s by one of her chromosomes shattering into pieces and reassembling. Scientists traced the woman's improvement to the removal of a harmful gene through this scrambling of DNA in one of her blood stem cells-a recently identified phenomenon that until now had only been linked to cancer.

We know poisonous snakes are dangerous, but what exactly makes venom so powerful? Evolutionary biology tells us why venom is useful for snakes, but chemistry tells us how venom works. This week, Reactions sheds some light on the proteins in venom, as well as its potential medical uses

How are these two terms defined? How are they similar, and what are the differences between benign and malignant tumors?
