A new study examined the data behind the arguments for each vocalization and found that the answer was more nuanced than they thought -- and that it could depend on the shape of a few small bones.

To enable the quantitative assessment of these processes, researchers need to know the so-called 'turnover number' (for short: kcat) of the enzymes. A team of bioinformaticians now describes a tool for predicting this parameter for various enzymes using AI methods.

By examining one of the largest global Pliocene collections of fossils in Langebaanweg, north of Cape Town in South Africa, researchers present two new sabertooth species and the first family tree of the region's ancient sabertooths. Their results suggest that the distribution of sabertooths throughout ancient Africa might have been different than previously assumed, and the study provides important information about Africa's paleoenvironment.

Although the idea may be commendable, getting it right is not so easy. Scientists see shortcomings in the reintroduction plan: In southern Africa, cheetahs live in a stable socio-spatial system with widely spread territories and densities of less than one individual per 100 km².

The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.

The survey reveals the iconic predator resides across most of Glacier's 1,600 square-mile landscape, although at lower densities than in the core of its range further north.

Their unique sense of balance has more in common with humans than it may appear. Researchers are studying cat locomotion to better understand how the spinal cord works to help humans with partial spinal cord damage walk and maintain balance.

They developed close bonds with the rodent-eating cats that conveniently served as ancient pest-control in society's first civilizations. A new study found this lifestyle transition for humans was the catalyst that sparked the world's first domestication of cats, and as humans began to travel the world, they brought their new feline friends along with them.

A team has now shown that several mammalian species on farmland in Namibia maintain a network for intra- and interspecific communication at cheetah trees. Black-backed jackals, African wildcats and warthogs visited and sniffed the cheetahs' 'places to be' more frequently than control trees, the team concluded from photos and videos recorded by wildlife camera traps. A common prey species of the cheetahs, however, avoided these hotspots.
