As Africa prepares for the arrival of a powerful El Niño weather event, an international team of researchers has found that access to improved forecasts alone will not protect many of the region’s poorest livestock farmers from the impacts of climate change.

A new silicon metasurface capable of rapidly controlling wide-bandwidth light pulses could help advance compact technologies for optical communications, computing, LiDAR and photonic information processing. The approach combines broad spectral operation with picosecond-scale switching, addressing a longstanding trade-off between modulation strength and bandwidth in ultrafast optical devices.

By reinforcing ice with tiny plant-based crystals and a specially designed protein, researchers created a material that rivals concrete in strength and absorbs 70 times more energy before breaking.

A pixel-controlled programmable metasurface capable of dynamically reshaping terahertz (THz) waves could open new possibilities for compact imaging, communications and optical systems. The device functions as a phase-type spatial terahertz modulator, combining independent pixel-level encoding with the ability to switch between multiple optical functions on a single platform.
