SAN DIEGO — Kurt looks and acts like any other young horse. He scampers and strides on springy legs, testing their strength. When it’s time to recharge, he nuzzles up to his mother for some nourishing milk.But Kurt is no ordinary horse. Kurt is a clone.The 2-month-old colt is a Przewalski’s horse, a species native to central Asia that once went extinct in the wild and is still critically endangered, with only about 2,000 remaining.San Diego Zoo Global researchers have high hopes that Kurt can help turn things around for his species. He was cloned from skin cells taken from a stallion in 1980 a...
DETROIT — It’s a mystery. Invasive sea lamprey, the Great Lakes’ biggest predator, primarily feed on lake trout, one of the lakes’ most prized sports fish. When trout populations are high, researchers expect to see fewer lamprey-wounded fish, and more of those wounds when lamprey populations are spiking.But that’s not always what scientists are finding.New research into what may be behind the discrepancies holds promise to improve how sea lampreys are controlled in the Great Lakes, protecting a $7 billion fishery. It could allow lamprey managers to examine whether they have switched to other f...
The evolution of language converted a defenceless naked ape into a world-dominating force. It fundamentally transformed how humans transmit information and knowledge. A large and potent component of language is our ability to communicate about things that are not here, that happened in the past, or that will happen in the future. This feature of language is known as “displaced reference”.
Just over three years ago, I was clinging to a rock in 20 meters of water, trying to stop the current from pulling me out to sea. I peered out into the gloom of the Pacific. Suddenly, three big dark shapes came into view, moving in a jerky, yet somehow smooth and majestic manner. I looked directly into the left eyes of hammerhead sharks as they swam past, maybe 10 meters from me. I could see the gill slits, the brown skin. But most of all, what struck me was just how big these animals are—far from the biggest sharks in the seas, but incredibly powerfully built and solid. These are truly magnificent creatures.
In his homily for the state funeral of George H.W. Bush on December 5, Rev. Russell Levenson Jr. joked that Sully, Bush’s loyal service dog, had probably received more press attention in recent days than the former president himself. That sentiment echoed Fala, President Franklin Delano Roosevelt’s Scottish terrier, who was so popular with the American public that he received more fan mail than the president himself.
At the end of September, four rescued orangutans returned to their home in the rainforest after undergoing lengthy rehabilitation at International Animal Rescue’s (IAR) conservation center in West Borneo, where I work as a chief executive. Amy, Kepo, Ongky and Rambo had been rescued by our Orangutan Protection Unit at various times during the previous eight years. They then joined 100 other orangutans at the center being meticulously prepared for life back in the wild by our dedicated team of vets and caregivers.
A towering elm tree stands 30 meters tall, somewhere near the border between England and Scotland, defying the fate that so many of its cousins met when Dutch elm disease ravaged the species in the 1970s. One of relatively few elm trees left, it is a haven for wildlife. Look closely and you can see the erratic fluttering of a small brown butterfly, with a W-shaped white streak across its wing.
A warehouse filled with huge gleaming silver vats hums around the clock, as billions of yeast cells work to make a material we can wear, sit on and carry around. In an adjoining room, rows of benches hold molds of different shapes and sizes, where sheets of cellulose layer up and become recognizable. In the next room, the material is finished and packaged, destined for designers, tailors and upholsterers.
Many children play with toys that evoke the bucolic life on a farm. And many will likely visit a small local farm, where animals have space and access to sunlight and the outdoors. But most kids are probably not aware that, for the vast majority of farmed animals, life is anything but happy.
The world’s plastic problem may seem vast and incalculable, but its footprint has actually been measured. In a sweeping 2015 study, researchers calculated that 9 billion tons of the material have been made, distributed and disposed in fewer than 70 years. That’s an astonishing figure, but it’s also one that’s hard to picture. Perhaps a better way to illustrate the problem of plastics is by looking at the damage that can be caused by a single drinking straw.
In 2015, a team of marine biologists in Costa Rica pried a plastic straw from the nose of a male olive ridley sea turtle. Footage of the excruciating, bloody extraction was posted online and viewed by millions of people around the globe. The video is powerful not only because it suggests the pervasiveness of plastics and shows the harm it can inflict on a vulnerable species, but it also strikes a much deeper chord within: shame.
“Subconsciously, people who watched the video knew that the straw in that turtle’s nose could have been thrown away by any of us,” Christine Figgener, the biologist who extracted the straw, wrote in a Medium post after the video went viral. “They saw their own actions reflected in its eyes.”
Drug Enforcement Administration officials are alerting doctors to a fairly new and potentially widespread development in the opioid crisis: In the hunt for drugs, some people are abusing their own pets to obtain narcotics from veterinarians, according to a new report by the Courier Journal in Louisville, KY.
