Analyzing samples from a prospective study, University of California San Diego School of Medicine researchers found that human exposure to glyphosate, a chemical widely found in weed killers, has increased approximately 500 percent since the introduction of genetically modified crops.

An estimated 1.9 million U.S. homes could be flooded by 2100 if seas rise 6 feet in response to climate change, according to a new analysis by the real estate company Zillow. The affected properties are valued at $916 billion dollars and represent 1.8 percent of the country’s housing stock.

 It’s open season for Canada geese in Illinois from mid-October to mid-January. Unfortunately for hunters, Canada geese are finding a new way to stay out of the line of fire. Rather than being “sitting ducks” in a rural pond, they’re setting up residence in the city.

Saline lakes around the world are shrinking in size at alarming rates. But what—or who—is to blame?

Until recently, glaciers in the United States have been measured in two ways: placing stakes in the snow, as federal scientists have done each year since 1957 at South Cascade Glacier in Washington state; or tracking glacier area using photographs from airplanes and satellites.

Groundwater may play an unrecognized role in thawing Arctic permafrost following wildfires, according to new research.

Tuna is one of the most ubiquitous seafoods. It can be eaten from a can or as high-end sashimi and in many forms in between. But some species are over-fished and some fishing methods are unsustainable. How do you know which type of tuna you’re eating?

Some tuna is certified as sustainably caught by groups such as the Marine Stewardship Council (MSC) that set standards for sustainable fishing. But these certifications are only good if they are credible.

Tropical rainforests continue to buffer wildlife from extreme temperatures even after logging, a new study has revealed.

Microseismic signals could aid in imaging subsurface geology

Scientists from Rice University and Texas A&M University-Corpus Christi’s Harte Research Institute for Gulf of Mexico Studies have discovered that Earth’s sea level did not rise steadily but rather in sharp, punctuated bursts when the planet’s glaciers melted during the period of global warming at the close of the last ice age. The researchers found fossil evidence in drowned reefs offshore Texas that showed sea level rose in several bursts ranging in length from a few decades to one century.
