Scientists have employed inventive chemistry to produce an injectable biomaterial with significantly improved adhesive strength, stretchability, and toughness. This chemically modified, gelatin-based hydrogel had attractive features, including rapid gelation at room temperature and tunable levels of adhesion. This custom-engineered biomaterial is ideal as a surgical wound sealant, with its controllable adhesion and injectability and its superior adherence to a variety of tissue and organ surfaces.

Is the eye a window into aging? New research has shown how imaging of the fundus, the blood vessel-rich tissue in the retina, can be used to track human aging, in a way that is noninvasive, less expensive and more accurate than other aging clocks that are currently available. Researchers also did a genome-wide association study (GWAS) to establish the genetic basis for such a clock, which they call eyeAge.

Cancer-associated fibroblasts (CAFs) are key factors in the tumor microenvironment, which have been implicated in cancer cell progression. It has also been reported that vesicles called exosomes produced by these CAFs play an important role in cancer progression. A research group investigated the effect of CAF-derived exosomes on the growth of malignant melanoma cells. They found that CAF-derived exosomes express CD9 and CD63 transmembrane proteins, and that the CD9-positive exosomes may inhibit the growth of malignant melanoma cells.

In interventions designed to encourage more sustainable and climate-smart behavior, examples of what other people are doing and financial 'carrots' are more important than providing knowledge and facts. This has been shown in an international second-order meta-analysis of more than four hundred primary studies. However, all types of climate mitigation interventions have a relatively small effect on how people behave.
