A pulse of innovation: AI at the service of heart research      (via sciencedaily.com)     Original source 

Researchers unveiled BeatProfiler, a groundbreaking new tool -- a comprehensive software that automates the analysis of heart cell function from video data. It's the first system to integrate the analysis of different heart function indicators, such as contractility, calcium handling, and force output into one tool, speeding up the process significantly and reducing the chance for errors. BeatProfiler enabled the researchers to not only distinguish between different diseases and levels of their severity but also to rapidly and objectively test drugs that affect heart function.

eDNA methods give a real-time look at coral reef health      (via sciencedaily.com)     Original source 

The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.

Four in five bird species cannot tolerate intense human pressures      (via sciencedaily.com)     Original source 

In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations.

What four decades of canned salmon reveal about marine food webs      (via sciencedaily.com)     Original source 

Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.

Computer scientists show the way: AI models need not be SO power hungry      (via sciencedaily.com)     Original source 

The development of AI models is an overlooked climate culprit. Computer scientists have created a recipe book for designing AI models that use much less energy without compromising performance. They argue that a model's energy consumption and carbon footprint should be a fixed criterion when designing and training AI models.

Groundbreaking research in groundwater's role in ecosystem sustainability      (via sciencedaily.com)     Original source 

Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.

Older trees help to protect an endangered species      (via sciencedaily.com)     Original source 

The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.

I spy with my speedy eye: Scientists discover speed of visual perception ranges widely in humans      (via sciencedaily.com)     Original source 

Using a blink-and-you'll-miss-it experiment, researchers have discovered that individuals differ widely in the rate at which they perceive visual signals. Some people perceive a rapidly changing visual cue at frequencies that others cannot, which means some access more visual information per timeframe than others. This discovery suggests some people have an innate advantage in certain settings where response time is crucial, such as in ball sports, or in competitive gaming.

Melting glaciers in a warmer climate provide new ground for invasive species      (via sciencedaily.com)     Original source 

In 2022 and 2023, biologists from research institutes in the UK and the Falkland Islands led two expeditions to South Georgia to study the impacts of invasive species on this cold and rugged sub-Antarctic island. They report that several invasive plants and invertebrates rapidly colonized the new ground exposed by melting glaciers, leaving few pristine areas for native species. With ongoing climate change, more research is needed across the world to understand how invasive species impact the fragile ecosystems that develop after glacier melting.

Seeing the forest for the trees: Species diversity is directly correlated with productivity in eastern U.S. forests      (via sciencedaily.com)     Original source 

When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.
