Island birds more adaptable than previously thought      (via sciencedaily.com)     Original source 

The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.

Improved wildfire smoke model identifies areas for public health intervention      (via sciencedaily.com)     Original source 

The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.

Climate resilience strategies in urban, rural areas      (via sciencedaily.com)     Original source 

Local decision-makers looking for ways to reduce the impact of heat waves on their communities have a valuable new capability at their disposal: a new study on vegetation resilience. Scientists completed a study of how well vegetation survived extreme heat events in both urban and rural communities across the country in recent years. The analysis informs pathways for climate mitigation, including ways to reduce the effect of urban heat islands.

Rock steady: Study reveals new mechanism to explain how continents stabilized      (via sciencedaily.com)     Original source 

Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism may explain how the cratons formed some 3 billion years ago, an enduring question in the study of Earth's history.

Hubble views a galaxy with a voracious black hole      (via sciencedaily.com)     Original source 

Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).

Quantifying U.S. health impacts from gas stoves      (via sciencedaily.com)     Original source 

A new study of air pollution in U.S. homes reveals how much gas and propane stoves increase people's exposure to nitrogen dioxide, a pollutant linked to childhood asthma. Even in bedrooms far from kitchens, concentrations frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off.

Did a magnetic field collapse trigger the emergence of animals?      (via sciencedaily.com)     Original source 

Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels that may have been crucial to the proliferation of life forms millions of years ago.
