Most caviar comes from the Caspian Sea, but the decline of sturgeon there is driving fishermen and poachers to fish populations in the Pacific Northwest’s Columbia River. Wildlife managers have resorted to patrolling along the shorelines, looking for signs of illegally caught sturgeon. They've even gone undercover to meet with poachers.
Glaciers are key contributors to drinking water supplies, hydropower generation and salmon survival in the Pacific Northwest. Scientists aren’t sure exactly when the glaciers will disappear. It could be within a few decades. It has been 4,000 years since the glaciers have receded this much.
Whether it’s driving five miles over the speed limit or breezing past a stop sign on your bike, chances are, we have all broken a few — or more — rules of the road. When it comes to obeying traffic laws, “we’re all criminals,” says the author of this survey.
The largest solar flare of the year erupted from the sun earlier this month. Space weather is the stuff that gets spewed out by the sun and other stars -- electromagnetic energy, solar material. It travels through the solar system and interacts with everything it comes across, including the Earth's magnetic field. While we're mostly protected from harmful radiation, solar activity is sometimes disruptive and predicting it is difficult.
Talcum powder has been used for more than a century on babies and many people use it for daily hygiene. But a spate of recent lawsuits and some studies suggest using talc could lead to ovarian cancer in adult women. Still, the science is far from settled.
At its height in 1980, the wolf population on Isle Royale National Park numbered as many as 50 individuals. But now, with just three individuals remaining, the wolves’ doom is virtually assured.
Even with good intentions and legitimate potential medical applications, gene research poses ethical debate and concern among scientists, many of whom have called for a worldwide moratorium on its use. That's no different for a new method called CRISPR, which is splitting scientific opinion.
Having to dump 3,000 to 5,000 pounds of shrimp is an economic and environmental problem for commercial fishing. But a team of government scientists may have found a simple, affordable solution to help shrimping trawlers avoid scooping up the wrong catch.
In their natural habitats, beavers and their dams are vital parts of the ecosystem. But in Patagonia, where the beaver is an invasive species, they're wreaking havoc on the local environment. Now the government is responding to stop the damage, and even local cooks are doing their part.
