Most cell structures are not visible to the naked eye without using stains for visualization. The stains used in these images highlight how cell biologists use tricks to “see the invisible.” Invite ...

In the 1950s, advances in microscopy techniques allowed scientists to visualize synaptic communication between two brain cells for the first time. 1,2 However, many details beyond the general synapse ...

Researchers have discovered that septins -- a part of the cytoskeleton -- form a barrier to the penetration of Pseudomonas aeruginosa. The process is dependent on the LecA molecule on the surface of ...

Researchers discover that actin acts in the cell nucleus and is partly responsible for the expression of male sexual characteristics. Steroid hormones, to which belong sex hormones like estrogen or ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

Researchers from Cleveland Clinic's Florida Research and Innovation Center (FRIC) found that disruption of a cellular structure, known as the actin cytoskeleton, is a "priming signal" for the body to ...

Plants are sessile organisms and are therefore exposed to damages caused by the predictable increase in temperature. We have analyzed the effects of temperatures on the development of pollen tubes by ...

Surrounded by nutrients and undetected by the immune system, the interior of a cell is the ideal place for pathogenic bacteria to reproduce. Nevertheless, it was long thought that they existed outside ...
