Novel tissue substitute made of high-tech fibers
Regenerative medicine uses cells harvested from the patient's own body to heal damaged tissue. Fraunhofer researchers have developed a cell-free substrate containing proteins to which autologous cells bind ...
Novel plastic could spur new green energy applications, 'artificial muscles'
A plastic used in filters and tubing has an unusual trait: It can produce electricity when pulled or pressed. This ability has been used in small ways, but now researchers are coaxing fibers of the material ...
First contracting human muscle grown in laboratory
In a laboratory first, Duke researchers have grown human skeletal muscle that contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals.
Nothing to squirm about: Space station worms help battle muscle and bone loss
It is said that great things can come in small packages. In this case, one key to keeping astronauts healthy on long-duration space missions may be found in a tiny roundworm barely a millimeter long.
Research in rodents suggests potential for 'in body' muscle regeneration
What if repairing large segments of damaged muscle tissue was as simple as mobilizing the body's stem cells to the site of the injury? New research in mice and rats, conducted at Wake Forest Baptist Medical Center's Institute ...
Artificial muscle made of fishing line is 100 times stronger than yours
By taking simple sewing thread and fishing wire and giving it a twist, scientists have created artificial muscle that's 100 times stronger than human or animal sinew. The invention, described in the journal Science, could ...
A novel insight into cardiac function: Development of a new model of spontaneous oscillatory contraction
Researchers have successfully developed a realistic theoretical model that provides a rational explanation for the spontaneous oscillatory contraction (SPOC) of muscle. The findings were published in Physical Re ...
Bats use blood to reshape tongue for feeding
Nectar-feeding bats and busy janitors have at least two things in common: They want to wipe up as much liquid as they can as fast as they can, and they have specific equipment for the job. A study in the Proceedings of th ...
Scientists uncover the nuclear life of actin
A key building block of life, actin is one of the most abundant and highly conserved proteins in eukaryotic cells.
Research provides key insight into how cells fuse
Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and ...
Researcher discovers plankton adjusts to changing ocean temperatures
(Phys.org) —It was often assumed marine plankton would be easy prey, especially in the dense viscosity of colder waters, but that is not necessarily so.
Ractopamine is safe for use in Brazilian pork
Animal scientists in Brazil have found that a small dose of the feed additive ractopamine can boost pork production without changing how pork looks or tastes.
Lizard tails detach at a biological 'dotted line'
Like sheets of paper marked with perforated lines, gecko tails have unique structural marks that help them sever their tails to make a quick getaway. Though voluntarily shedding a body part in this manner ...
Stem cells + nanofibers = Promising nerve research
Every week in his clinic at the University of Michigan, neurologist Joseph Corey, M.D., Ph.D., treats patients whose nerves are dying or shrinking due to disease or injury.
