New study reveals that corals in the Gulf of Aqaba have withstood four consecutive and intensifying marine heatwaves, including the world’s most extreme 2024 event, without suffering mass bleaching — a resilience unmatched elsewhere. This is important because coral reefs globally are collapsing under rising ocean temperatures, threatening ecosystems and human livelihoods. The Gulf of Aqaba may represent one of the planet’s last natural refuges for reef survival, offering a crucial model for understanding resilience and underscoring the urgency of protecting this unique ecosystem before even it reaches its limits. New study reveals resilience of Red Sea corals in the face of intensifying climate threats.

As a flexible and efficient non-contact processing technology, femtosecond laser has been widely applied in various micro/nano-precision engineering, leveraging its ultra-short pulse duration and ultra-high peak power density

Layered sodium manganese oxides (Na_2/3MnO₂) are promising cathode materials for developing high-capacity sodium-ion batteries. However, they suffer from severe capacity fading during cycling. In a new study, researchers systematically investigated how scandium doping can improve the cycling stability of P’2 polytype of Na_2/3MnO₂, revealing a new design strategy for developing long-life and high-capacity sodium-ion batteries for commercial applications.

Time division multiplexing (TDM) architecture is an important approach to creating sensor arrays for massive scale monitoring. But it is paradoxical for the TDM interferometric sensor array to keep a short delay fiber for high sensing resolution and meanwhile use low sampling rate for practical applications. In this paper, a phase matching sampling (PMS) paradigm is proposed to address the above contradiction.

This study shows how the interplay of ink composition and printing design shapes the structure, strength, and bioactivity of 3D-printed bone implants. By adjusting these factors, researchers achieved implants that better guide bone cell growth while maintaining stability, advancing personalized treatment for bone repair.
