Cell membrane: Like cornstarch and water
U. OREGON (US) — It turns out that cell membranes behave a lot like water and cornstarch. At rest they are very fluid, but when quickly perturbed, they bounce back like rubber. (more…)

Atomic-scale model unravels ion channel gating
U. ILLINOIS (US)—Nerve cells power human intelligence and behavior through electrical signals that rely on potassium and sodium ion channels to do their job, and an important part of that biological process involves a gating mechanism for generating and controlling the signals in those channels. (more…)

Workouts strengthen endothelial cells’ grasp
U. PENN (US)—Bioengineers have demonstrated that the cells that line blood vessels respond to mechanical forces—the microscopic tugging and pulling on cellular structures—by reinforcing and growing their connections, thus creating stronger adhesive interactions between neighboring cells. (more…)
