New genetic cause of cardiac failure discovered
Over the course of a lifetime, the heart pumps some 250 million liters of blood through the body. In the order to do this, the muscle fibers of the heart have to be extremely durable. The research group headed by Dr. Wolfgang ...

Biophysics: Order in chaos
The process of skeletal muscle contraction is based around protein filaments sliding inside sarcomeres — the structural units of muscle fiber. Inside each sarcomere is a set of filament motors, which ...

Let's stretch... Scientists study myomesin protein
The proteins actin, myosin and titin are big players in the business of muscle contraction. Scientists at the European Molecular Biology Laboratory (EMBL) in Hamburg, Germany, have now examined another muscle protein – ...

Cells are crawling all over our bodies, but how?
(PhysOrg.com) -- For better and for worse, human health depends on a cell's motility -- the ability to crawl from place to place. In every human body, millions of cells –are crawling around doing mostly ...

Researchers explain how railways in cells are built
Every cell in the human body contains a complex system to transport essential cargoes such as proteins and membrane vesicles from one point to another. These tiny molecular motor proteins move at high speeds on miniature ...

Oocytes: Going with the flow
Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation ...

Scientists discover new hitch to link nerve cell motors to their cargo
from the blink of an eye to running a marathon—nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers (neurotransmitters) that excite muscles ...

Nano-motor with a light switch: Light-triggered myosin allows real-time study of cells
(PhysOrg.com) -- Molecular "motors" are at the root of most biological movement. They propel cell components, whole cells, and even our muscles on command. Barbara Imperiali and a team from the Massachusetts ...

Salmonella utilize multiple modes of infection
Scientists from the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany have discovered a new, hitherto unknown mechanism of Salmonella invasion into gut cells: In this entry mode, the bacteria exploit the mu ...
