Less intensively managed grasslands have higher plant diversity and better soil health, research shows for first time

Researchers found that less intensively managed grasslands had greater diversity of plant species and correlated with better soil health, including increased nitrogen and carbon levels. In contrast, intensively farmed plots showed fewer plant species, but some saw improvements in soil health over time.

Researchers from Gwangju Institute of Science and Technology develop an intelligent observer for Esports

A new intelligent observer for Esports has been developed using a Mask R-CNN algorithm to learn from human spectating data. This approach overcomes limitations of existing automatic observers, which require extensive domain knowledge and cannot capture undefined events or changes in event significance.

Fireworks have long-lasting effects on wild birds

Wild geese in Germany, Denmark, and the Netherlands experience significant changes in their behavior after fireworks, including flying further and foraging more, even after the disturbances end. The effects persist for up to two weeks, with birds leaving their sleeping sites and flying hundreds of kilometers non-stop.
