Did you know that there’s a natural carbon sink—even bigger than the Amazon rainforest—that helps regulate Earth’s climate by sucking up to six billion tons of carbon from the air each year?

Habitat loss, pesticide use and, surprisingly, artificial light are the three most serious threats endangering fireflies across the globe, raising the spectre of extinction for certain species and related impacts on biodiversity and ecotourism, according to a Tufts University-led team of biologists associated with the International Union for the Conservation of Nature.

A new study shows that polar bears are spending less time on sea ice, leading them to fast longer, become thinner and have fewer cubs.

Historic rainfall in southeastern Brazil has created deadly floods and widespread destruction in a region that was experimenting with “more progressive” planning and zoning policies than most, says Northeastern political science professor Thomas Vicino, who studies metropolitan development and housing in Brazil.

A new study suggests the Western Antarctic Ice Sheet is less stable than researchers once thought. As in the past, its collapse in the future is likely.

Coastal plant communities are a crucial element of global sea defences but are increasingly threatened by the human-induced effects of climate change, according to new research.

At the beginning of each summer, mayfly larvae emerge from bodies of water and shed their skin to become full-fledged mayflies, similar to how caterpillars become butterflies.

Excess selenium from fertilizers and other natural sources can create air pollution that could lead to lung cancer, asthma, and Type 2 diabetes, according to new UC Riverside research.

When food makes people sick, some blame birds because they hang around farms, and their feces can contain E. coli, Salmonella and Campylobacter, three common pathogens that can cause food-borne illness.

As Arctic sea ice retreats, human activity in the region increases, but the region remains hazardous.
