Container's material properties affect the viscosity of water at the nanoscale
Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic.
Extinctions of large animals sever the Earth's 'nutrient arteries' (Update)
(Phys.org) —A new study has demonstrated that large animals have acted as carriers of key nutrients to plants and animals over thousands of years and on continental scales.
Sunbathing helps these bugs stay healthy
Sunbathing may be healthy – at least for one group of North American insects that apparently uses the activity to fight off germs, Simon Fraser University scientists have found.
Primate hibernation more common than previously thought
(Phys.org) —Until recently, the only primate known to hibernate as a survival strategy was a creature called the western fat-tailed dwarf lemur, a tropical tree-dweller from the African island of Madagascar.
Study shows extinction of pseudosuchians may have helped dinosaurs flourish
Dinosaurs were lighter than previously thought, new study shows
