Bears scratched trees to keep ticks away
(ORDO NEWS) — Brown bears rub against trees to repel parasites with the smell of tar. Experiments have shown that ticks parasitizing these predators are afraid of the smell of turpentine and beech tar. Thus, by rubbing against the trunk properly, the bear will protect itself from ticks and get rid of those that have already settled on its body. In addition, scratching on trees allows you to get rid…

Scientists have found that ancient people hunted cave bears for the skin
(ORDO NEWS) — At the site of ancient people in the German city of Schöningem, the remains of cave bears with traces of careful skinning and related tools were found. Scientists believe that these dangerous predators were deliberately hunted because of their warm skin. Evidence of the exploitation of bear skins is about 320 thousand years old. These are the bones of bears with incisions in those places from which…

Zoologists have found that bears in zoos are slowly killed by malnutrition
(ORDO NEWS) — Scientists at the University of Washington have found that captive bears can become omnivorous like their wild counterparts when given the opportunity, and this diet can prolong the animals’ lives. In most zoos, it is recommended that all bear species be fed a high protein diet, meaning that their diet contains mostly animal products. The same is true for cats, for example. But they are obligate predators,…

8 proteins keep hibernating bears in control of insulin levels
(ORDO NEWS) — Every year, bears living in the north go into hibernation, during which it is extremely important for them to maintain stable blood sugar levels. American scientists have been able to identify potential genetic clues to the bearish ability to control insulin levels, and in the future this may lead to effective treatment of diabetes in humans. The behavior of wild bears is a real nightmare for people…

Hibernating bears have a secret superpower lurking in their blood
(ORDO NEWS) — There is something curious in the blood of black bears that allows them to hibernate for seven months of the year, while remaining fit and healthy. Scientists aren’t sure what it is, but a new study has helped get closer to unraveling the mystery. If we humans tried to hibernate for as long as a black bear, our muscles would begin to wear out from lack of…

Blood plasma of sleeping bears will protect our muscles from degradation during immobility
(ORDO NEWS) — Treatment of muscle cells with plasma obtained from hibernating bears stimulated their activity and growth, although biologists have not been able to determine which protein triggers these processes. Japanese biologists have shown that blood plasma obtained from hibernating bears enhances the metabolism of human muscle cells, while plasma taken during the normal period does not have such an effect. Scientists suspect that a certain protein that accumulates…

Scientists have found similarities in the evolution of humans and bears
(ORDO NEWS) — The history of the formation of polar and brown bears largely coincides with the history of the development of relations between different branches of humanity. This is reported in a study by American and Finnish scientists, writes Proceedings of the National Academy of Sciences. “The history of polar and brown bears is a fairly accurate analog of human evolution. Scientists once thought that humans and Neanderthals simply…

5 bears lay down in hibernation under the house of Californians
(ORDO NEWS) — Residents of the Californian city of South Lake Tahoe discovered a family of baribal bears in the underground of their house, which hibernated here all winter. The shelter was chosen by a female with three relatives and one adopted cub. To avoid conflicts with animals, the residents had to call in specialists who drove the uninvited guests away. Houses around Lake Tahoe attract 100 to 150 bears…

Hibernation on the way to Mars as a bear hibernation
(ORDO NEWS) — Hibernating astronauts could be the best way to cut mission costs, reduce spacecraft size by a third, and keep the crew healthy on the way to Mars. A new study led by European scientists shows that human hibernation is beyond science fiction and could change the way we think about long-term space travel. When engineers plan a round-trip space mission to the Red Planet, they envision roughly…

Mysterious Footprints In Tanzania Made By Early Humans, Not Bears
(ORDO NEWS) — The oldest unequivocal evidence of upright walking in the human lineage are footprints discovered at Laetoli, Tanzania in 1978, by paleontologist Mary Leakey and her team. The bipedal trackways date to 3.7 million years ago. Another set of mysterious footprints was partially excavated at nearby Site A in 1976 but dismissed as possibly being made by a bear. A recent re-excavation of the Site A footprints at…
