Thanks to a new Kremlin-produced video, we know now that Russian President Vladimir Putin is quite the fisherman. The video is of Putin catching what the Kremlin claims is a 46-pound pike — and then kissing it.
In Texas, Thelma and Louise is a big draw. Not the movie — Thelma and Louise is the name of a two-headed turtle born at the San Antonio Zoo last month. The Texas cooter is so popular, she has her own Facebook page and more than 1,700 friends.
Biologists have discovered they can track hard-to-see species in streams, ponds and even the ocean by sampling the water for DNA. Scientists say the technique is an important conservation tool: So far, it's been used to track declining giant salamanders and even locate a rare whale.
The Mount Charleston blue butterfly is found only in a couple of small patches high in Nevada's Spring Mountains. But the Carpenter 1 fire, which has been raging through the area since July 1, is threatening the land and scientists fear the fire could push the butterflies into extinction.
Dolphins, like humans, are part of complex social networks. And research now indicates that they use their unique whistle sounds to identify and communicate with each other. "Every time a dolphin heard its signature whistle, it called back, sometimes multiple times," one researcher says.
In the South African park, two cheetahs were chasing a herd of impala. Seconds from becoming dinner, one of the impala decided to make a tourist's SUV its get-away car. The animal jumped into an open window of the vehicle, which stopped the cheetahs in their tracks.
A break-in at the store had Australian police stumped. There was a hole in the ceiling and smashed merchandise but nothing was missing. The next day the intruder was found still inside the store. The python was 19 feet long and weighed 37 pounds.
In Montana's Centennial Valley, conservationists made a grievous mistake while trying to save the trumpeter swan — they nearly wiped out Arctic grayling. Now they're looking for ways to make sure both species get a place on the ark.
A fossilized tyrannosaur tooth found lodged between bones in a hadrosaur's tail is giving paleobiologists pretty firm clues about the tyrant king's meal plan. And Hollywood may have been right all along — T. Rex definitely knew how to kill.
A few dog breeds indigenous to North America have genetic roots on the continent that stretch back 1,000 years or more. A study finds that their genetic lineages haven't changed much, despite an influx of European pooches.
The chicken-size sage grouse is as much a part of America's Western range as antelopes and cowboys. The birds nest beneath sagebrush, and as it disappears, so do the grouse. Biologists hope to protect the bird without starting a 21st century range war.
