: Cancer is caused by disruptions in the homeostatic state of normal cells, which results in dysregulation of the cell cycle, and uncontrolled growth and proliferation in affected cells to form tumors. Successful development of tumorous cells proceeds through the activation of pathways promoting cell development and functionality, as well as the suppression of immune signaling pathways; thereby providing these cells with proliferative advantages, which subsequently metastasize into surrounding tissues. These effects are primarily caused by the upregulation of oncogenes, of which SPP1 (secreted phosphoprotein 1), a non-collagenous bone matrix protein, is one of the most well-known.

Betalains, a distinctive group of nitrogen-containing pigments exclusive to the Caryophyllales order, possess diverse biological activities such as antioxidant, anti-inflammatory, and antimicrobial properties, making them highly valuable for applications in food, nutraceutical, and pharmaceutical industries. This Review provides a comprehensive analysis of betalain biosynthesis, structural diversity, and ecological significance, highlighting their roles in enhancing stress resilience, adaptation mechanisms, and plant evolutionary strategies. The evolutionary development of betalains is explored, revealing their emergence through gene duplication events and providing insights into their mutual exclusivity with anthocyanins.

The optoelectronic memristor integrates the multifunctionalities of image sensing, storage, and processing, which has been considered as the leading candidate to construct novel neuromorphic visual system. In particular, memristive materials with all-optical modulation and complementary metal oxide semiconductor (CMOS) compatibility are highly desired for energy-efficient image perception. As a p-type oxide material, CuO exhibits outstanding theoretical photoelectric conversion efficiency and broadband photoresponse.

Inspired by the fundamental attribute of chirality in nature, chiral-engineered biomaterials now represent a groundbreaking frontier in biomedical fields. However, the integration of chirality within inorganic materials remains a critical challenge and developments of chirality-induced bionic bone implants are still in infancy. In this view, novel chiral hydroxyapatite (CHA) coated Ti alloys are successfully synthesized by a sophisticated chiral molecule-induced self-assembly method for the first time.
