New research indicates that mitigating both local land and sea-based human impacts, especially in terms of pollutants and over-fishing, provides coral reef ecosystems with the best opportunity to persist under climate change. Along some highly populated areas on the shorelines of Hawai'i, wastewater pollution and urban runoff combine with fishing pressures to put immense stress on coral reefs.

In-water monitoring shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. AIMS' Annual Summary Report on Coral Reef Condition for 2022/23 found that while some reefs continued to recover, their increased hard coral cover was offset by coral loss on other reefs. Most reefs underwent little change in coral cover.

Scientists have worked out how one unusual species of trilobite -- an ancient, sea-dwelling relative of spiders and lobsters -- was able to defend itself against predators and survive a bumpy ride as Earth's oxygen levels fluctuated.

The success of artificial intelligence technologies depends largely on how physicians interpret and act upon a tool's risk predictions -- and that requires a unique set of skills that many are currently lacking, according to a new perspective article.

New study identifies concerning gaps between how human radiologists score the accuracy of AI-generated radiology reports and how automated systems score them. Researchers designed two novel scoring systems that outperform current automated systems that evaluate the accuracy of AI narrative reports. Reliable scoring systems that accurately gauge the performance of AI models are critical for ensuring that AI continues to improve and that clinicians can trust them.

Resilient corals, often referred to as 'super corals', have recently been seen as potential saviours in the face of climate change and its detrimental effects on coral reefs. Now, a team of scientists is working to better understand these corals in order to develop strategies to protect fragile ecosystems such as the Great Barrier Reef.

Researchers have developed a highly efficient method to investigate systems with long-range interactions that were previously puzzling to experts. These systems can be gases or even solid materials such as magnets whose atoms interact not only with their neighbors but also far beyond.

Some of the world's most distinct and ancient animal species, which play crucial roles in our planet's ecosystems, are exploited for the wildlife trade across large parts of the world, according to new research.

Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.

Deep in the tropical Andes, a genus called Nasa harbored elusive and forgotten plant species. Through the collaborative efforts of botanists and citizen scientists on iNaturalist, these plants have been rediscovered after decades, some even after more than a century.
