Collective cell migration relies on a directional signal that comes from the moving cluster, rather than from external cues.
A handful of species have learned how to survive in freezing climates. To do so, the animals must counteract the damaging effects of ice crystal formation, or keep from freezing altogether. Here are a few ways they do it.
Watch the cell transplant experiments in zebrafish that suggest certain embryonic cells rely on intrinsic directional cues for collective migration.
With dogged persistence and an unwillingness to entertain defeat, Bruce Beutler discovered a receptor that powers the innate immune response to infections—and earned his share of a Nobel Prize.
Animals and plants come in a dizzying array of colors. Current research is cracking into the remarkable structures behind nature's artistic display.
Some of these insidious viruses expertly subvert the host immune system, allowing their unhindered proliferation.
Tracking the genetic diversity and evolution of rhinoviruses can lead to a better understanding of viral evolution, the common cold, and more dangerous infections.
Researchers are working to understand how often-colorless biological nanostructures give rise to some of the most spectacular technicolor displays in nature.
