A new study from University of Utah researchers suggests that due to deforestation and habitat degradation, more bird species may be endangered that previously thought—including species that may not have been discovered yet. The study is published in Frontiers in Ecology and Evolution.

As a result of logging and severe bushfires, Australian wildlife is facing a severe shortage of tree hollows—holes in the trunks and branches of large old trees. More than 300 species of birds and mammals, including possums, bats, cockatoos, owls and kookaburras, rely on tree hollows for shelter or breeding.

With Oskar Aszmann and his team at the Department of Plastic, Reconstructive and Aesthetic Surgery, MedUni Vienna has long been regarded as a world leader in bionic limb reconstruction. It was only last year that the world's first fully integrated bionic arm prosthesis was developed at MedUni Vienna. This is ready-to-use and is described as "Plug and Play." Although all bionic aids have so far been used in humans, the technique known as osseointegration (direct skeletal attachment) has now been […]

Sweet pittosporum (Pittosporum undulatum) was once a well-behaved tree growing in gullies from Gippsland in Victoria up to Brisbane in Queensland.
