Earliest evidence of flip flops in the Middle Stone Age
In a twist in the ancient human story, emerging evidence suggests that we may have worn shoes as early as the Middle Stone Age (75,000—150,000 years ago). This could mean that our species had complex cognitive and practical abilities much earlier t.....»»
Anisotropic lattice induces high-Q chiroptical responses in surface lattice resonance metasurfaces
Chirality is an intrinsic property of an object that cannot coincide with its mirror image by translation or rotation. In order to realize strong chiral light-matter interactions which are usually weak in natural materials for practical applications,.....»»
