Yellowstone Park researchers know winter is on the way out when they see a grizzly bear out of its den and feasting on lunch after long months of hibernation. "Scientists spotted the first grizzly bear of 2026 earlier this week at Yellowstone National Park, marking the beginning of the end of hibernation season for the massive creatures," reports Emily Mae Czachor of CBS News. "The grizzly observed this year was seen in the backcountry, scavenging on the carcass of a bull bison, another species found in the park." 

 

When spring starts its seasonal orchestra, the percussion section begins with the staccato drums of male woodpeckers trying to out "hammer" each other to win over female woodpeckers. "The emphatic drumming, meant to attract mates and drive off rival males, is by no means the only way woodpeckers are at the pulse of things," writes Margaret Roach of The New York Times. Abandoned woodpecker nests are repurposed into homes by "wood ducks, owls, bluebirds, tree swallows, squirrels, martens, bats and raccoons" to name a few. Woodpecker: A Year in the Life of North American Woodpeckers is a new book by author and wildlife photographer Paul Bannick that gives rich insight into how humans can help nature's amazing builders.

Chestnut trees that once filled American forests until an airborne blight and root rot pushed them to the brink of extinction might once again compete for space in forests from Maine to Mississippi. "A new study in the journal Science provides hope for its revitalization, finding that the genetic testing of individual trees can reveal which are most likely to resist disease and grow tall, thus shortening how long it takes to plant the next, more robust, generation," reports Michael Phillis of The Associated Press. "A smaller gap between generations means a faster path to lots of disease-resistant trees. . . . The authors hope that can occur in the coming decades."

They're cracked, green and more than a little nutty. Meet the American pistachio. It's an alternate-bearing crop that's gaining international popularity, especially when mixed with chocolate. "The U.S. pistachio industry appears to be attracting more demand as its supply could soon reach 2 billion pounds," reports Todd Fitchette of Western Farm Press. "The popularity of a chocolate bar created in Dubai with crushed pistachios in it has helped bolster global pistachio demand in other products. . . .The U.S. currently controls the world’s pistachio market share with about 63% of the global supply."

In some hard-to-crack crime cases, there's often a trail that leads to a remote location where a body is disposed of, leaving nearby flora as the only witness. And while plants can't talk, many a detective knows that foliage can still tell part of the story. More recently, forensic botanists are analyzing moss for clues. "Particles from the dense, green mats can easily attach to a suspect’s shoes or clothing, grow on human remains and survive in adverse conditions," reports Samantha Drake of The New York Times. Moss samples can help detectives determine postmortem timelines, "track a suspect’s movements and establish key links to help solve crimes including homicides, missing person cases and cemetery desecrations."

Research efforts in Wisconsin that are focused on bald eagle health are helping scientists determine PFAS levels in human populations across the state. "Dubbed 'forever chemicals,' PFAS don’t break down easily and are found in common household products," Sea Grant for the University of Wisconsin reports. "They’re harmful to human health and have been found in high concentrations in drinking water in communities across Wisconsin. The project's emerging contaminants specialist, Gavin Dehnert, said eagles are what’s known as a 'sentinel species,' organisms that can alert humans to environmental toxins. Due to their diet, bald eagles are particularly good indicators of how much PFAS are in the environment."
