On Endangered Koalas, Scientists Hit on 'Way to Bring Them Back'

Freezing koala sperm would require fewer koalas in captivity, improve genetic diversity: report

America Used to Have Lots of Llamas. And Now?

Seems a market that once included wealthy athletes and high-flying celebs quietly slid off a...

Farmers Worried as Death Rates Surge for Female Pigs

Agriculture industry trying to get a handle on problem with sows

(Newser) - Operators of farms with a large number of female pigs are seeing a worrying trend—death rates are surging among the sows. One industry group, Swine Management Services, says the death rate increased from 5.8% to 10.2% from 2013 to 2016, per National Hog Farmer . "This makes...

Scientists: We Know Why Sheep Get Sexed Up in Winter

Scientist figure out how melatonin levels affect breeding

(Newser) - "Why do sheep get frisky in winter?" isn't the beginning of a bad joke, but rather the question that jump-started a joint study by researchers at the University of Nottingham and the University of Bristol. The Guardian reports that scientists may now have an answer, one that could...

Cows Once as Big as Elephants May Soon Roam Europe

Welcome back the aurochs, or something like it

(Newser) - Standing nearly as tall as an elephant, the aurochs grazed for 250,000 years until its extinction in 1627. But its story may not end there: Scientists say they are close to resurrecting the "supercow," once the largest land mammal in Europe, reports CNN . In search of herbivores...

Study Shows Why Giant Pandas Need Tinder

Mutual attraction drastically increases the likelihood of panda babies

(Newser) - The scientist who invents a Tinder for giant pandas may just single-handedly save the endangered species.

Inside the Insanely Tricky Process of Breeding Pandas

Cross your fingers: a panda cub could be on the way

(Newser) - Congratulations are in order for the National Zoo's female giant panda—or so veterinarians hope based on an ultrasound yesterday: Mei Xiang is presumably pregnant. Experts are cautious as the 1.5-inch-long fetus could still be reabsorbed or the panda could miscarry. Research vet Pierre Comizzoli says the ultrasound...

Jawbone Lifts Lid on Human-Neanderthal Sex

Shows interbreeding occurred in Europe 37K to 42K years ago

(Newser) - A jawbone found in Romania more than a decade ago provides the first genetic evidence that humans and Neanderthals knocked boots in Europe before the latter disappeared between 35,000 and 40,000 years ago.

Why Pigs Don't Have Sex Anymore

Artificial insemination is better and faster for farmers

(Newser) - Pity the modern boar: He roams the pen for a sow that's ready to breed and when he's about to, er, take action, a farmer appears with a catheter in his hands. The poor guy has been replaced by artificial insemination. That's because nearly 90% of today'...

(Newser) - Do you have a burning desire to know your cat's ancestry? Are you dying to know if she's really a pure Abyssinian or if the guy at the pet store ripped you off? Well, now you can. Lyons Feline Genetics Laboratory at the University of California now offers...

Why Dog History Remains a Blur

Those darn Victorians did it

(Newser) - Our ignorance about canine history can be blamed, ironically, on our own love for dogs, LiveScience reports. Scientists recently tried tracing dogs' genetic lines—and culling out details of their early domestication—but lost track in the 19th century, when Victorians established today's standard breeds. The 15,000 years...

'Gay' Penguins to Be Split Up at Zoo
