This animation shows how the proton gradient across the mitochondrial membrane powers the ATP synthase enzyme to make ATP. It is the third of three animations about cellular respiration.

This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the second of three animations about cellular respiration.

This animation shows the reactions of the citric acid cycle, which splits off carbon atoms and generates energy-rich reduced forms of cofactor molecules. It is the first of three animations about cellular respiration.

The COVID-19 pandemic has spotlighted the importance of having a scientifically literate public. In this article, Pennsylvania educator Bob Cooper unpacks how to utilize BioInteractive's suite of infectious disease resources to teach students scientific literacy. 

This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.

For the first time, scientists have shown that hummingbirds can sing and hear in pitches beyond the known range of other birds, according to research published Friday in the journal Science Advances.

This article by professor Melissa Haswell sequences a four-week evolution module that minimizes lecture while teaching students to think like scientists. 

The flu vaccine did a disappointing job last winter in the U.S., and officials worry that might be a bad sign for the fall.

For centuries, scientists have obsessed over a primordial blob that can shape-shift, clone itself, and live indefinitely.

This film explores how life recovered after an asteroid wiped out the dinosaurs and how those events shaped the diversity of plants and mammals on Earth today.

Rutgers University researchers have received U.S. government clearance for the first saliva test to help diagnose COVID-19, a new approach that could help expand testing options and reduce risks of infection for health care workers.
