An Historical Survey on Light Technologies [PDF]
, 2018 Following the celebration of the International Year of Light and Light-based Technologies in 2015, this paper presents a survey of the exploitation of light throughout our history. Human beings started using light far into the Stone Age, in order to meet

Advanced Healthcare Materials, EarlyView.This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence
Advanced Healthcare Materials, EarlyView.Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

The structure of the Middle Stone Age of eastern Africa
Quaternary Science Reviews, 2018 Abstract The Middle Stone Age (MSA) of eastern Africa has a long history of research and is accompanied by a rich fossil record, which, combined with its geographic location, have led it to play an important role in investigating the origins and expansions of Homo sapiens. Recent evidence has suggested an earlier appearance of our species, indicating

Advanced Healthcare Materials, EarlyView.This review examines how in vitro electrical and mechanical stimulation modulates wound healing in fibroblasts and keratinocytes. Analyzing over 560 experimental data points, we relate stimulation parameters to proliferation and migration outcomes, evaluate platform designs, and highlight the need for multi‐parameter optimization to advance targeted ...
