Solid-state qubits: Forget about being clean, embrace mess      (via sciencedaily.com)     Original source 

New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.

A global study reveals pathways to save threatened sharks, despite rising mortality trends      (via sciencedaily.com)     Original source 

Sharks have persisted as powerful ocean predators for more than 400 million years. They survived five mass extinctions, diversifying into an amazing variety of forms and lifestyles. But this ancient lineage is now among the world's most threatened species groups due to overexploitation in poorly regulated fisheries and the proliferation of wasteful finning practices.

Generating stable qubits at room temperature      (via sciencedaily.com)     Original source 

Quantum bits, or qubits, can revolutionize computing and sensing systems. However, cryogenic temperatures are required to ensure the stability of qubits. In a groundbreaking study, researchers observed stable molecular qubits of four electron spins at room temperature for the first time by suppressing the mobility of a dye molecule within a metal-organic framework. Their innovative molecular design opens doors to materials that could drive the development of quantum technologies capable of functioning in real-world conditions.

Focus on biological processes does not capture the whole picture      (via sciencedaily.com)     Original source 

The ocean plays a crucial role in the storage of carbon dioxide (CO2). The so-called marine biological carbon pump is an important research topic in this context. However a key component is often overlooked. Colleagues outline why it is insufficient to focus solely on biological processes when investigating the accumulation of CO2 in the ocean by the biological carbon pump.

Protecting coral 'nurseries' as important as safeguarding established coral reefs      (via sciencedaily.com)     Original source 

New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.
