Darwin’s Ground Sloth

New research published in the journal Scientific Reports provides the first direct evidence of omnivory in an ancient sloth species. Reconstruction of the Darwin’s ground sloth (Mylodon darwinii) feeding on the carcass of the hoofed native herbivore Macrauchenia. These extinct mammals roamed the Pleistocene landscape of Patagonia and other parts …

Cats Hunt Wild Prey

Predation of wildlife by domestic cats (Felis catus) presents a threat to biodiversity conservation in some ecological contexts. The proportions of wild prey captured and eaten by domestic cats and thus the contributions of wild prey to cat diets are hard to quantify. In a new study published in the …

Lake Breach Floods

Massive floods from overflowing crater lakes were responsible for eroding at least 24% of the volume of incised valleys on early Mars, according to new research led by University of Texas at Austin planetary scientists. Valley networks and paleolake outlet canyons on Mars: (a) distribution of analyzed valley networks (black) …

Superionic Water’s

Using machine learning, a team of physicists at Lawrence Livermore National Laboratory has studied the phase behaviors of superionic water — a phase of water where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline lattice — with unprecedented resolution. Hydrogen atoms diffuse easily between the superionic …

Vampire Bats

During nightly foraging trips, closely bonded females of common vampire bats (Desmodus rotundus) depart their roost separately, but often reunite far outside the roost to hunt together, says a new paper published today in the journal PLoS Biology. The common vampire bats (Desmodus rotundus). Image credit: Uwe Schmidt. Vampire bats …

Bipedal Dinosaurs

The tail of bipedal non-avian dinosaurs played a role analogous to the swinging arms of humans during walking and running, according to new research led by Harvard University’s Dr. Peter Bishop. Computer simulations of running locomotion in a modern tinamou bird (brown) and the extinct theropod dinosaur Coelophysis (green). Gray …

Tardigrades Walking

Tardigrades utilize a tetrapod-like stepping pattern remarkably similar to that observed in insects, despite significant disparities in size and skeletal structure between the two groups, according to new research led by scientists from Rockefeller and Princeton Universities. Hypsibius exemplaris. Image credit: Tarushika Vasanthan & Jonathon Stone, doi: 10.22120/jwb.2020.96855.1037. The vast …

Vocal Learning Avians

An international team of scientists led by Flinders University has found evidence of prenatal auditory learning in embryos of three vocal learning species (superb fairy-wren, red-winged fairy-wren and Darwin’s small ground finch) and two vocal non-learning species (little penguin and Japanese quail). Colombelli-Négrel et al. demonstrate a capacity to perceive …

Fish Neck-Like Motion

Trout and frogfish can bend their spines and heads upwards, despite having different anatomy from humans and other land-dwelling vertebrates, according to a study by University of Liverpool’s Dr. Ariel Camp. Craniovertebral skeleton of the Commerson’s frogfish (Antennarius commerson). Image credit: Ariel L. Camp, doi: 10.1098/rspb.2021.1091. Dr. Camp used X-ray …

Tardigrades Resembling Insects

Tardigrades utilize a tetrapod-like stepping pattern remarkably similar to that observed in insects, despite significant disparities in size and skeletal structure between the two groups, according to new research led by scientists from Rockefeller and Princeton Universities.
