Amembrane made from threads of a polymer commonly used in vascular sutures can be loaded with therapeutic drugs and implanted in the body, where mechanical forces activate the polymer's electric potential and slowly release ...
Inside our cells, and those of the most well-known lifeforms, exist a variety of complex compounds known as "molecular motors." These biological machines are essential for various types of movement in living systems, from ...
Substantial tissue loss can be the result from different causes, including cancer, injury, and infection. Reconstructive surgery attempts to mitigate the damage. Currently, the clinical "gold standard" in the field of reconstructive ...
Traffic accidents, tumor resections, and congenital diseases can cause significant trauma, which can lead to large bone deformations and/or bone loss. Although bone has some capacity to regenerate, large bone defects cannot ...
Engineers have developed a new material that mimics human cartilage—the body's shock absorbing and lubrication system, and it could herald the development of a new generation of lightweight bearings.
In two decades orbiting the Earth the International Space Station has become a cutting-edge cosmic laboratory, with astronauts researching everything from black holes to disease and even gardening in microgravity.
A 3D biomaterial scaffold design to slowly release stem cells ensures that implanted stem cells stick around to relieve pain and reverse arthritis in mice knee joints. This reduces the use of stem cells by 90%, thus avoiding ...
A new automated process prints a peptide-based hydrogel scaffold containing uniformly distributed cells. The scaffolds hold their shapes well and successfully facilitate cell growth that lasts for weeks.
Researchers at the University of Southampton have developed a new way of using nanomaterials to identify and enrich skeletal stem cells—a discovery which could eventually lead to new treatments for major bone fractures ...
For the first time in 11 years, the European Space Agency (Esa) is recruiting new astronauts. Applications will open on the 31 March 2021 for eight weeks, followed by a six-stage selection process to identify the next generation ...
