Minerals can be key to healing damaged tissue
Every species, from bacteria to humans, is capable of regeneration. Regeneration is mediated by the molecular processes that regulate gene expression to control tissue renewal, restoration and growth......»»
Cell fate choice during adult regeneration is highly disorganized, study finds
A team of scientists at the Whitehead Institute for Biomedical Research and MIT has spatially mapped the choices stem cells make during tissue regeneration in flatworms, revealing an unexpected finding: Rather than being organized into homogeneous ne.....»»
Reprogramming tissue mechanically to promote wound healing
Researchers at PSI and ETH Zurich have taken connective tissue cells that have been mechanically reprogrammed to resemble stem cells and transplanted them into damaged skin. In their laboratory experiment, they were able to show that this can promote.....»»
Sensitive ecosystems at risk from mine waste, finds study
Nearly a third of the world's mine tailings are stored within or near protected conservation areas, University of Queensland research has found. A study led by UQ's Bora Aska, from the Sustainable Minerals Institute and School of the Environment, sai.....»»
Enhancing the immunosuppressive properties of human umbilical cord mesenchymal stem cells
Mesenchymal stem cells (MSCs) have great potential for the treatment of various immune diseases due to their unique immunomodulatory properties. However, MSCs exposed to the harsh inflammatory environment of damaged tissue after intravenous transplan.....»»
Dynamic bio-interface between mussel tissue and byssus plays important role in quick release
A team of chemists at McGill University, working with a colleague from Charité-Universitätsmedizin, in Germany, has uncovered part of the process used by mussels to bind to rocks and to quickly release from them when conditions warrant......»»
Microautophagy is essential for preventing aging, finds lysosomes study
To age or not to age? How does aging affect organisms on a cellular level? What mechanisms help cells survive self-inflicted or external harm? It is known that lysosomes—critically important cellular structures—are crucial for digesting damaged c.....»»

Researcher: Big cats eat more monkeys in a damaged tropical forest, which threatens survival of primate populations
Monkeys are not usually a popular menu item for big cats. Primates are, after all, hard to catch: living in the canopies of large trees and rarely coming down to the ground. Jaguar and puma have varied diets and will normally hunt the species that ar.....»»
Exploring design rules for using supramolecular hydrogels to mimic the extracellular matrix
In human tissue, the cells are embedded in the extracellular matrix. This matrix is made up of fiber-like structures that provide firmness to the tissue, but also influence cell behavior and facilitate cell growth......»»
Residents get brief return to volcano-risk Icelandic town
From Christmas gifts to sheep, residents forced from an Icelandic town damaged by hundreds of earthquakes in recent days were able to briefly return on Monday to retrieve their belongings, authorities said......»»

Researchers can now visualize osmotic pressure in living tissue
In order to survive, organisms must control the pressure inside them, from the single-cell level to tissues and organs. Measuring these pressures in living cells and tissues in physiological conditions is a challenge......»»
Modern medicine"s Middle Ages roots—how the logic of vulture brain remedies and bloodletting lives on today
Nothing calls to mind nonsensical treatments and bizarre religious healing rituals as easily as the notion of Dark Age medicine. "The Saturday Night Live" sketch "Medieval Barber Theodoric of York" says it all with its portrayal of a quack doctor who.....»»

Uncovering the link between cell biomechanics and wound healing
An interdisciplinary team of researchers from the Indian Institute of Science (IISc) has uncovered how the stiffness of a cell's microenvironment influences its form and function. The team was led by Namrata Gundiah, Professor at the Department of Me.....»»
How bacteria support wound healing
Although they were not recognized as agents of disease until the late 19th century, the detrimental effects of bacterial infections have been known to humans for thousands of years. Some have even become mythical—for example, during the American Ci.....»»
