Molecular tools for coral reef restoration: Beyond biomarker discovery

Conservation Letters, 2020
As coral reefs continue to decline due to climate change and other stressors, scientists have proposed adopting genomic tools, such as biomarkers, to aid in the conservation and restoration of these threatened ecosystems.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

A comparative evaluation of satellite and bio-argo-based net primary productivity algorithms for the north Indian Ocean

Discover Oceans
We estimate the net primary productivity (NPP) based on bio-argo measurements using three algorithms: Vertically Generalised Production Model (VGPM), Eppley-VGPM and the original Carbon-based Production Model (CbPM).

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

4D Insights into Coral Biomineralization: Effects of Ocean Acidification on the Early Skeleton Development of a Stony Coral

Advanced Science, EarlyView.
Early coral skeletons grow through formation of two co‐joined zones, rapid accretion deposits and thickening deposits. Advanced imaging and simulations reveal that ocean acidification reshapes these zones, shifting the coral portfolio of mineral phases which alters skeletal resistance to mechanical stress.
