Angle-dependent holograms made possible by metasurfaces

The expression “flawless from every angle” is commonly used to characterize a celebrity’s appearance. This doesn’t simply imply that they appear attractive from a specific viewpoint, but rather that their appeal remains consistent and appealing from various angles and perspectives. Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurface … Read more

Seaports found to be hotspots of contagious cancer in mussels

MtBTN2 cells under microscope (× 100 magnification). They are characterized by their large size, prominent nucleus, and scarce cytoplasm. In contrast, a healthy cell—a haemocyte of smaller size with more abundant cytoplasm—is visible on the bottom right.

Did neanderthals use glue? Researchers find evidence that sticks

Angle-dependent holograms made possible by metasurfaces

Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought. The work, reported in the journal Science Advances, … Read more
