When tau proteins build up in human brains, they form tangles that progressively get worse causing memories and motor function to diminish. Hibernating bears also experience a massive accumulation of tau in the brain (the proteins may help protect neurons during inactivity), but hibernating bears can quickly clear out the tau-tangles upon wakening with their […]
(NEXSTAR) – Nine species could soon find themselves on federal threatened or endangered species list, the U.S. Fish and Wildlife Service says. After reviewing eight species native to the United States and two from Southeast Asia, wildlife officials determined nine of them warrant advancing to the next step under the Endangered Species Act. Before being […]
Two million species are at risk of extinction, a figure that is double previous UN estimates, new analysis has found. From a report: While scientists have long documented the decline of species of plants and vertebrates, there has always been significant uncertainty over insects, with the UN making a “tentative estimate” of 10% threatened with […]
An anonymous reader shares an article: In 1937, a brown, eyeless beetle was found in a few caves in Slovenia. The new species was unexceptional apart from one feature. Its discoverer decided to name it after Adolf Hitler. Anophthalmus hitleri has an objectionable sound to modern ears. Nor is it alone. Many species’ names recall […]
This article was updated at 3:32 p.m. EDT. Deep-frozen wildlife cell samples could enable the future cloning of at-risk species under a technically adventurous initiative by the Fish and Wildlife Service and its private partners. Dubbed “biobanking,” the collaborative effort has identified 24 endangered animals whose tissue collections may be shelved in one of two […]

The San Diego Zoo Wildlife Alliance is joining a world-wide effort to preserve species diversity by entering into a partnership with the International Union for the Conservation of Nature (IUNC). The group supports conservation at the nation’s zoos, aquariums, and botanical gardens. The local institution focuses on sharing knowledge developed, while caring for genetic material […]
An anonymous reader quotes a report from Phys.Org: A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. […]
The black rail bird may soon be listed as a threatened species in Pennsylvania. The Pennsylvania Board of Game Commissioners voted to preliminarily reclassify the shorebird as state-threatened during a two-day meeting in Erie Sept. 15-16. The proposal will be voted on for final consideration at the January board meeting. “Black rail is our smallest […]
Invasive species are costing the world at least $423bn every year and have become a leading threat to the diversity of life on Earth, according to a UN assessment. From a news report: From invasive mice that eat seabird chicks in their nests to non-native grasses that helped fuel and intensify last month’s deadly fires […]
