In this article, see a learning sequence where students explore symbiotic relationships and cell communication in bacteria (quorum sensing) by connecting their prior knowledge regarding ocean ecosystems to their understanding of symbiotic relationships.

With demand for COVID-19 vaccines outpacing the world’s supplies, a frustrated public and policymakers want to know: How can we get more? A lot more. Right away.

The world’s vital insect kingdom is undergoing “death by a thousand cuts,” the world’s top bug experts said.

Identical twins are not exactly genetically the same, new research shows.

The COVID-19 pandemic has helped revive the autopsy.

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.

This three-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

Every year, as many as 400 million people are infected with life-threatening diseases by the Aedes aegypti mosquito. It wasn’t always so dangerous.

The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.

Desperate to solve the deadly conundrum of COVID-19, the world is clamoring for fast answers and solutions from a research system not built for haste.
