Scientists name a new cat species for the first time in over a century (opens the original)
Read excerpt
For the first time in a century, scientists have identified a new cat species, thanks to genetic analysis — and it's resolved a long-standing debate about the cat family tree. The newly identified species, Leopardus tilcayo, is a type of tiger cat — a small, spotted wild cat — that lives in the Yungas cloud forest region of Bolivia. The analysis also revealed a subspecies of another tiger cat species, named Leopardus tigrinus antisuyo, which lives in Peru. Previously thought to be a northern
'It's in the realm of possibility': Climate change is spurring a reemergence of yellow fever, and the US could face future threats (opens the original)
Read excerpt
Yellow fever is appearing in regions that haven't seen cases of the disease in years, largely as a result of climate change. Historically, the virus ravaged cities across the Americas, Europe and Africa, until a vaccine was introduced in 1937 and its range shrunk significantly. But now, as climate change creates favorable conditions for virus-carrying mosquitoes, scientists are seeing outbreaks in unexpected areas. "Yellow fever is a highly deadly disease," Dr. Joelle Ivy Rosser, an infectious-d
Do other animals call each other by name? (opens the original)
Read excerpt
Every person you know has a name, and you've likely given one to your pets, too. But are names a uniquely human feature, or do other animals also call each other by name? Research suggests that some mammals and birds use vocal labels for other individuals, but not all scientists agree on how to interpret the evidence. In the 1960s, scientists discovered that young bottlenose dolphins (Tursiops) create individually distinctive whistles, called signature whistles. Researchers in the years since ha
500-year-old Inca mummies prove that European colonists brought devastating smallpox to the Americas (opens the original)
Read excerpt
Two Chilean mummies have provided scientists with the earliest known smallpox genomes found in the Americas, dating between 1492 and 1631. The genomes are the first-ever DNA evidence that proves European colonization introduced smallpox to the Americas, according to a paper that published Thursday (July 30) in the journal Science. Smallpox, an infection caused by the variola virus, was one of the deadliest diseases in the world until it was completely eradicated in 1980. While the disease has be
