bear : any of a family of large heavy mammals of America and Eurasia that have long shaggy hair, rudimentary tails, and plantigrade feet and feed largely on fruit, plant matter, and insects as well as on flesh — Webster
Bears are carnivoran mammals of the family Ursidae. Bears are classified as caniforms, or doglike carnivorans. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found on the continents of North America, South America, Europe, and Asia. Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails.
While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets. With the exception of courting individuals and mothers with their young, bears are typically solitary animals. They may be diurnal or nocturnal and have an excellent sense of smell. Despite their heavy build and awkward gait, they are adept runners, climbers, and swimmers. Bears use shelters, such as caves and logs, as their dens; most species occupy their dens during the winter for a long period of hibernation, up to 100 days. — Wikipedia

Genomes of two millipede species shed light on...

Millipedes, those many-legged denizens of the soil surface throughout the world, don't always get the recognition they deserve. But a new study by Jerome Hui of Chinese University of Hong Kong and colleagues puts them in the spotlight, sequencing and analyzing complete genomes from two very different millipede species. The study, publishing on September 29th in the open-access journal PLOS Biology, provides important insights into arthropod evolution, and highlights the genetic underpinnings of […]

Fire and logging are substantially reducing the number of hollow-bearing trees that threatened and critically endangered Australian mammals can use as homes, a new study from The Australian National University (ANU) warns.

A small subpopulation of polar bears lives on what used to be thick, multiyear sea ice far above the Arctic Circle. The roughly 300 to 350 bears in Kane Basin, a frigid channel between Canada's Ellesmere Island and Greenland, make up about 1-2% of the world's polar bears.
Wild birds as offerings to the Egyptian gods
on September 22, 2020 at 7:37 pm
Millions of ibis and birds of prey mummies, sacrificed to the Egyptian gods Horus, Ra or Thoth, have been discovered in the necropolises of the Nile Valley. Such a quantity of mummified birds raises the question of their origin: Were they bred, like cats, or were they hunted? Scientists from the CNRS, the Université Claude Bernard Lyon 1 and the C2RMF have carried out extensive geochemical analyses on mummies from the Musée des Confluences, Lyon. According to their results, published on 22nd […]
