Brain tumours are one of the most deadly and noticeable types of cancer, affecting both children and adults. One of the major drawbacks in brain tumour identification is the late diagnosis and high cost of brain tumour-detecting devices. Most existing approaches use ML algorithms to address problems, but they have drawbacks such as low accuracy, high loss, and high computing cost.

Cephalopods such as squids, octopuses, and cuttlefishes can change their bodies' color to match the surrounding environments by contracting or expanding the sac just below the surface of the skin. Inspired by this mechanism, artificial cephalopod chromatophores which are prepared by thermoresponsive poly(N-isopropyl acrylamide)-based hydrogel films embedded with black, red, and yellow pigments are presented, they can swell and shrink under temperature stimuli, like the natural chromatophores. The artificial chromatophores embedded with cuttlefish ink are further used to fabricate artificial J.

Thermal transport in nanostructures plays a critical role in modern technologies. As devices shrink, techniques that can measure thermal properties at nanometer and nanosecond scales are increasingly needed to capture transient, out-of-equilibrium phenomena. We present a novel pump-probe photon-electron method within a scanning transmission electron microscope (STEM) to map temperature dynamics with unprecedented spatial and temporal resolutions.

During mouse embryonic development, the embryonic day (E) 5.5 stage represents a crucial period for the formation of the primitive body axis, where the symmetry breaking of cellular states influences the multicellular system. Elucidating the detailed mechanisms of this process necessitates a trans-layered dynamic observation of the embryo and all internal cells.

Vanadium dioxide (VO) has attracted significant attention in aqueous zinc ion batteries (AZIBs) owing to their desirable theoretical specific capacity originated from multiple electrons transfer reaction and special crystal structure. However, sluggish electrochemical kinetics leads to inferior electrochemical storage performance. Herein, rich vanadium vacancies were introduced in tunnel VO to boost Zn diffusion, increasing charge storage capacity and lengthen lifespan.
