Two-way traffic enable proteins to get where needed, avoid disease
It turns out that your messenger RNA may catch more than one ride to get where it's going.
All aboard the nanotrain network
Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists at Oxford University and Warwick University.
Dissecting the brain's primary developmental engine
Identification of a plant-specific nanomachine regulating nuclear movement
A group led by Professor Ikuko Hara-Nishimura (Department of Botany, Graduate School of Science) revealed the molecular mechanism underlying nuclear movement in plants.
Research duo use X-rays and high speed camera to learn secrets of rapid wing beats of insects (w/ Video)
Bearing witness to the phenomenon of symmetric cell division
Writing in his journal about the scientists of his era, Henry David Thoreau bemoaned their blindness to significant phenomena: "The question is not what you look at, but what you see." More than 150 years ...
Physicists tease out twisted torques of DNA
Like an impossibly twisted telephone cord, DNA, the molecule that encodes genetic information, also often finds itself twisted into coils. This twisting, called supercoiling, is caused by enzymes that travel ...
How cells get a skeleton
The mechanism responsible for generating part of the skeletal support for the membrane in animal cells is not yet clearly understood. Now, Jean-François Joanny from the Physico Chemistry Curie Unit at the Curie Institute ...
A metal switch to control motor proteins
(Phys.org) —Molecular motor proteins inside the body, called kinesins, are a lot like the motor in your car. The molecular motors convert stored chemical energy into specific conformational changes, which ...
Key protein revealed as trigger for stem cell development
A natural trigger that enables stem cells to become any cell-type in the body has been discovered by scientists.
A nano-gear in a nano-motor inside you
Diverse cellular processes require many tiny force-generating motor proteins to work in a team. Paradoxically, nature often chooses the weak and inefficient dynein motor to generate large persistent forces ...
Scientists discover structure of protein essential for quality control, nerve function
(Phys.org)—Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered "quality-control" protein that is found in the cells ...
The guide to biomolecular movie-making
High-speed atomic force microscopy (HS-AFM) is providing the means to produce dramatic footage of moving biomolecules, and scientists at Kanazawa University leading the field.
How molecular transports change gear: Environment determines the motion of motor proteins
The motor protein myosin-V, which hauls molecular cargoes around cells by ratcheting along filaments of actin, switches between two different molecular mechanisms of movement depending on the environment. ...
