In one video, you can see a hungry caterpillar, first working around a leaf's edges, approaching the base of the leaf and, with one last bite, severing it from the rest of the plant. Within seconds, a blaze of fluorescent ...

Microbeads allow ultrasonic waves to stimulate cells more safely

Researchers at Duke University have discovered a way to enhance the effectiveness and safety of sonogenetics or ultrasonic modulation, emerging techniques that use sound waves to control the behavior of individual neurons ...

Cell signals that trigger wound healing are surprisingly complex

In a sharp and pointy world, wound healing is a critical and marvelous process. Despite a tremendous amount of scientific study, many outstanding mysteries still surround the way in which cells in living tissue respond to ...

Feeding caterpillars make leaves shine

When a plant is attacked by herbivores, this triggers a number of physiological responses in the plant. Calcium ions are important messengers for the processing of wound signals in plant cells. They regulate signal transduction ...
