Plant cell walls, composed primarily of cellulose, hemicellulose and pectins, serve as dynamic structures that not only provide mechanical strength and protection but also regulate growth, ...

Humans rely on the arsenal of cells, molecules, and biochemical pathways of the immune system to defend the body when it's threatened by pathogens. But there are many different biological mechanisms ...

For the first time, high-resolution time-lapse videos of tiny bits of living plants show how they assemble their protective cell walls, researchers report March 21 in Science Advances. The image ...

A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female ...

Similar to humans, plants have an immune system to help defend against parasites and other deleterious infections. The human body is interconnected with cell-to-cell communication to orchestrate an ...

In a narrow strip of land along the Andes mountain range in central Chile, an Indigenous community has long celebrated the ...

The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's ...

Plants adapt their water consumption to environmental conditions by counting and calculating environmental stimuli with their guard cells. Plants control their water consumption via adjustable pores ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on ...
