Nutrient Cycling in the Serengeti

In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment. 

Inheritance and Mutations in a Single-Gene Disorder

This activity builds on information presented in the short film Genes as Medicine. Students interpret actual pedigrees to determine the inheritance pattern of Leber congenital amaurosis (LCA), an inherited form of blindness.

Skin Color and Human Evolution

This activity guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.

Sodium Channel Evolution in Electric Fish

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

Testosterone Levels in Elite Athletes

This activity guides the analysis of a published scientific figure from a study that compared the testosterone levels of Olympic-level elite athletes.

White-Nose Syndrome

This activity explores images of bats with an infectious fungal disease, which serve as phenomena for learning about population dynamics and disease impacts.

Could anyone have stopped gene-edited babies experiment?

Early last year, a little-known Chinese researcher turned up at an elite meeting in Berkeley, California, where scientists and ethicists were discussing a technology that had shaken the field to its core — an emerging tool for “editing” genes, the strings of DNA that form the blueprint of life

Q&A on scientist’s bombshell claim of gene-edited babies

Designer babies might be here sooner than anyone reckoned. A Chinese researcher who says he created gene-edited babies crossed what most scientists consider a forbidden line.

It’s not clear if the claim is true and if so, how the twin girls whose DNA reportedly was altered will fare a

Chinese researcher claims first gene-edited babies

A Chinese researcher claims that he helped make the world’s first genetically edited babies — twin girls born this month whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life.

If true, it would be a profound leap of science and ethics.

Why Two Heads?

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
