There are major shifts underway in understanding the physiological mechanisms that control muscle contraction, a field that has been the focus of intense research for centuries.
A group of Marshall University researchers and their colleagues in Japan are conducting research that may lead to new ways to move or position single moleculesâ€”a necessary step if man someday hopes to build molecular machines or other devices capable of working at very small scales.
Chromosomes move faster than we first thought.
Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs â€” even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes.
Cells rely on tiny molecular motors to deliver cargo, such as mRNA and organelles, within the cell. The critical nature of this transport system is evidenced by the fact that disruption of motors by genetic defects leads to fatal diseases in humans.
Understanding how neurons migrate to their proper place during brain development will offer insights into how malfunctions in the machinery cause epilepsy and mental retardationMEMPHIS, Tenn., July 15 /PRNewswire-USNewswire/ -- The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St.
The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital.
Every cell lining the small intestine bristles with thousands of tightly packed microvilli that project into the gut lumen, forming a brush border that absorbs nutrients and protects the body from intestinal bacteria.
New research shows that muscle atrophy is a much more ordered and deliberate process than previously thought.
During desperate times, such as fasting, or muscle wasting that afflicts cancer or AIDS patients, the body cannibalizes itself, atrophying and breaking down skeletal muscle proteins to liberate amino acids.
