Calling all "Ice Age" lovers: The frozen remains of a 35,000-year-old saber-toothed cat have been studied for the first time in history, according to a study published Thursday in the journal Scientific Reports. A. shows the frozen mummy and B. shows Panthera leo (Linnaeus, 1758), a modern lion cub's remains. Its neck is also "longer and more than twice as thick" as the modern cub's. For "Ice Age" movie franchise fans, the description of the saber-toothed cat might sound familiar. The character Diego, a saber-toothed tiger, has very similar traits to the 35,000-year-old cub.

☆ Tourists are rushing to see glaciers before they disappear, but trips are turning deadly

The three people who lost their lives in Alaska are just a few of those who have died on trips to see the world’s fast-disappearing glaciers. But there’s also another motivation increasingly present — the desire to see the glaciers before they disappear. In Alaska, Sheldon used to be able to find a good area for ice climbing for the whole summer. Many are convinced danger is manageable, he told CNN, but “if you’re honest about it, that might often be a rather naive understanding.”As well the safety issues glaciers pose tourists, tourists are also a huge risk to the glaciers themselves. As the glaciers shift, so too will glacier tourism, something that’s starkly clear to Sheldon.

☆ German cockroaches’ unexpected origins revealed by genomic analysis

The nocturnal critter was most likely a German cockroach, and its ancestors were pestering people more than 2,000 years ago in southern Asia, a new study found. German cockroaches, scientifically known as Blattella germanica, are ubiquitous in cities in the United States and around the world. The research team received 281 German cockroach samples from 57 sites in 17 countries and studied their DNA to trace their evolution. And we know that transatlantic trade routes probably were the culprit for the spread of German cockroaches. “For example, the German cockroach has insecticide resistance that is not detected in many other pests,” he said.

☆ ‘How Life Works’ Review: More Than a Box of Chocolates

The frontispiece of the first edition of “Systema Naturae” (1735) depicts the botanist Carl Linnaeus as an Adam-like figure, liberally dispensing names to the newly generated creatures of the natural world. The notion reflected here, that living organisms are the immutable products of divine creation, was challenged in 1858 by the naturalists Charles Darwin and Alfred Russel Wallace. They argued that the apparent design of living things resulted, instead, from the incremental accumulation of innumerable small heritable changes over vast expanses of geological time. This and various other constraints—including the need to maintain sufficient plasticity for adaptability—mean that organisms are compromised, inevitably incorporating numerous vulnerabilities. These result, in the case of humans, in an assortment of ailments and a precarious relationship with mortality.
