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

- How did forelimb function change as vertebrates...on January 22, 2021 at 7:00 pm
When tetrapods (four-limbed vertebrates) began to move from water to land roughly 390 million years ago it set in motion the rise of lizards, birds, mammals, and all land animals that exist today, including humans and some aquatic vertebrates such as whales and dolphins.

Human activities might have shifted the movement of caribou in and near the Arctic National Wildlife Refuge, according to scientists with the University of Cincinnati.
- Swamp eel: Blood-red subterranean dweller is...on January 18, 2021 at 2:47 pm
Together with a group of international colleagues, Senckenberg scientist Ralf Britz described a new fish genus. The blind fishes, which are members of the swamp eel family, live in subterranean waters in Southern India and show a red coloration. Moreover, the team assigned three additional species to the new genus. The study was recently published in the scientific journal Ichthyological Exploration of Freshwaters.

The White-lipped peccary (Tayassu pecari) is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil's Atlantic Rainforest, they prefer the fruit of the jussara palm Euterpe edulis.
- Blending rules for 3-D printing boneon January 15, 2021 at 12:20 pm
By combining synthetic polymers and natural materials it is possible to increase the range of characteristics that might be fabricated using 3-D printing of components, according to research published in the International Journal of Nano and Biomaterials. In a proof of principle, the team has demonstrated how one such blend emulates the material properties of bone.
