Clean, safe water is vital for human health and well-being. It also plays a critical role in our food security, supports high-tech industries, and enables sustainable urbanisation. However, detecting contamination quickly and accurately remains a major challenge in many parts of the world. A groundbreaking new device developed by researchers at the National University of Singapore has the potential to significantly advance water quality monitoring and management.
The intricate, hidden processes that sustain coral life are being revealed through a new microscope developed by scientists at UC San Diego’s Scripps Institution of Oceanography.
The diver-operated microscope — called the Benthic Underwater Microscope imaging PAM, or BUMP — incorporates pulse amplitude modulated (PAM) light techniques to offer an unprecedented look at coral photosynthesis on micro-scales. Funded by the National Science Foundation, the new microscope will help scientists uncover precisely why corals bleach, and inform remediation efforts. While the bleaching process is known, it’s not fully understood, and it hasn’t been possible to study in depth in the field — until now.
