Keeping Kermit: New clues to protecting frogs from deadly Bd fungus

A new study from the University of South Australia shows that captive frogs can be protected from the deadly fungus Batrachochytrium dendrobatidis (Bd) through natural skin shedding processes. However, captivity also reduces skin bacteria diversity and richness, potentially affecting the frogs' resilience to pathogens.

Improving the robustness of bound states in the continuum with higher topological charges

The study proposes merging bound states in continuum (BICs) using higher topological charges, significantly enhancing Q factors and suppressing scattering loss. The approach enables steerable BICs with designed momentum, improving performance for direction-related applications.

Getting to the bottom of the Arctic sea ice decline: Investigation of heat movement near the North Pole and under the Arctic sea ice

Researchers studied heat movement near North Pole and under Arctic sea ice, providing insights into the mechanisms of Arctic sea ice decline. Their findings suggest that strong winds cause mixing of water where ice and ocean meet, leading to enhanced heat transfer and changes in seawater salinity.

New risk score predicts mortality for atrial fibrillation patients undergoing transcatheter aortic valve replacement

A new risk score can help predict mortality for patients with atrial fibrillation who have undergone successful TAVR and been discharged home. The risk score was developed using data from the ENVISAGE-TAVI AF trial, which found that patients with certain clinical risks were more likely to die within a year of discharge.
