Newly published results from a study on nutrition, food security and the environment in Saskatchewan First Nations show that food insecurity is a major concern and that many households would like more access to traditional foods.

In a first, researchers from the University of California, Irvine – as well as Switzerland’s University of Zurich, IBM Research-Zurich and UC Santa Cruz – have obtained direct images of dissolved organic carbon molecules from the ocean, allowing better analysis and characterization of compounds that play an important role in the Earth’s changing climate.

In a remote region of the Indian Ocean lies the source of a mysterious weather pattern with tentacles that stretch across the tropics, influencing everything from monsoons in India to heat waves and flooding in the United States.

Motion-sensor cameras are increasingly being used to track wildlife across the globe, from tigers in India to aardvarks in Africa. But combing through the millions of images captured by these systems is a time-consuming task. Now, scientists have discovered that artificial intelligence is as effective as human volunteers — and much faster — at identifying species in these largely untapped photo repositories.

Since the 1960s, scientists at the University of Vermont have been documenting the decline of red spruce trees, casualties of the damage caused by acid rain on northeastern forests.

But now, surprising new research shows that red spruce are making a comeback—and that a combination of reduced pollution mandated by the 1990 Amendments to the Clean Air Act and changing climate are behind the resurgence.
