Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth. “Many of us assume that being exposed to radiation or other harm in space would be reflected by increased aging.…

Wound healing is a complex biological process that involves various tissue structures and cells, both local and distant. One significant factor in this process is the presence of fetal microchimeric cells (FMCs) that enter the maternal circulation during pregnancy. These cells not only engraft into different organs but also nest in the maternal bone marrow…

Patients who undergo skin injuries endure hospital stays, infection and/or succumb to death; therefore, advances in wound healing aim to improve clinical practices underlying macroscale healing to effectively intervene in microscale pathophysiology. As a result, strategies that optimize wound healing have motivated the design of new therapeutic products. In a new report in Science Advances, Benjamin…

Credit: The KonG/Adobe Stock As lovers might vouch, complex nuances of touch, including nearness sans physical contact and gradations of tactile pressure, convey a rich sensory experience and multi-dimensional cognitive pursuits. Intelligent interactions between biological entities or machines and organisms require artificial skins that can perceive fluctuations of intensity and pre-contact proximity. Until now, advances…

The analysis of the role of the mitochondria in oxidative damage and skin aging has been a significant aspect of dermatological research. Mitochondria generate most reactive oxygen species (ROS) which, in excess, are cytotoxic and DNA-damaging and promote (photo-)aging. However, ROS also possesses key physiological and regulatory functions and mitochondrial dysfunction is prominent in several…
