Harvard engineers have built a chip-scale, twisted bilayer photonic crystal whose twist angle and spacing can be dynamically adjusted with a MEMS actuator to tune the chirality of light.

Coral reefs are being hit hard by the climate crisis, and timely interventions for their survival are a top priority. The Global Coral Tech Transfer Project enables SECORE International and the Australian Institute of Marine Science (AIMS) to implement the latest scientifically developed coral breeding techniques on a large scale across regions. The practical implementation of the project is carried out jointly and in close cooperation with Dominican Republic-based partner FUNDEMAR, combining Australian technology, Caribbean coral breeding science, and in-depth experience in implementing restoration efforts successfully. The goal is to create a comprehensive inventory of efficient and complementary methods, tools, and technologies to boost reef resilience worldwide. 

A new class of photonic devices enables the precise broadcasting of light from the chip into free space in a scalable way, which could lead to advanced displays, high-speed optical communications, and larger-scale quantum computers.
