Figure 1. Cladoselache fyleri, a chondrichthyan fossil preserved at an early stage of decay and disarticulation in an iron-carbonate concretion, collected by William Kepler between 1880 and 1886 from the Cleveland Shale Member of the Ohio Shale (Upper Devonian), Cleveland, Ohio, USA (above), and an interpretive sketch of the specimen (below). The cartilaginous bones of the skull, including the jaws, have largely disarticulated, and some of the tiny teeth are scattered nearby. The body was twisted just behind the pectoral fin, so the fossil appears in left-lateral view at the front, and in oblique-ventral view through most of the trunk and tail regions. A distinct rounded line surrounding the fish represents the margin of the microbial biofilm, or “decay halo,” that was responsible for early decay and also forming the concretion and preserving the fish remains. The fossil is 50 cm in length. This previously undescribed specimen was one of many surprises in the 19th-century geological collection of Ohio Wesleyan University, Delaware, Ohio.

iPSCs and NSCs model newborn brain injury

This article discusses research by Dr. Lee J. Martin and his team on HIE, a leading cause of neonatal mortality. They use human induced pluripotent stem cells (iPSCs) and neural stem cells (NSCs) and emphasize the vulnerability of oligodendrocytes, sharing how these cells can accumulate toxic misfolded proteins, potentially causing severe neural damage and long-term cognitive disabilities in affected infants.
Fig. 1. Overview of the HPK nano-bioparticle (NBP) technology. A, Schematic of technology. The HPK linear peptide (graphic) displays each functional domain in a different color. The schematic illustrates the self-assembly of HPK with various therapeutic cargoes into NBPs, which are designed to target tumors in the body. B, Data highlights of NBP technology. The ribbon structure of HPK shows color-coded domains and natural formation as a pentamer (appearing as rings under electron microscopy (EM) that self-assembles into NBPs (appearing as polyhedral under EM) upon exposure to cargo. IV injection in mice results in tumor-selective accumulation and delivery of therapeutic payload, reducing tumor growth.

Left, intact epithelium is a continuous sheet with an electrical potential across it, and signal molecules produced on one side (green) that cannot reach receptors (yellow) on the other side. A basement membrane (grey) separates epithelium from other cells. When the sheet is broken, as in a wound, cells change shape (‘EMT’) and send signals that include electric currents and interaction between signal molecules and receptors. The basement membrane may be breached, bringing epithelial cells in contact with other cells. Defence and repair cells (blue) respond. Right, in cancers, the epithelial sheet is disrupted, activating the same wound-healing changes.

Cancers are like wounds because they are damaged tissue

Cancers resemble wounds. The question is why, and what does this mean? Many features of cancers – the so-called ‘Hallmarks of Cancer’ – may be mostly a wound-healing response. Dr Paul Edwards, Emeritus Reader at the University of Cambridge explores.
