However, a new study of European jackdaws shows that this strategy has its limits: when sleep-deprived, these clever, social birds were more likely to fall into deep sleep in both brain halves – even ...

Birds, unlike humans, can sleep deeply with both halves of their brains (symmetrically) or with one half sleeping lighter than the other (asymmetrically). • Study of European jackdaws led by an ...

Scientists have discovered Ikaria wariootia, a 555-million-year-old fossil in Australia, believed to be the earliest ancestor ...

Cells constantly shift and transform, triggering the complex choreography that shapes living organisms. Whether dividing into new cells or sculpting an embryo, these tiny movements rely on chemical ...

The main cast of Animal Control are all returning for season 3, as Joel McHale, Michael Rowland, Vella Lovell, Ravi Patel, Grace Palmer and Gerry Dee were all mentioned in the official Animal Control ...

The speed was dominant on the right-side. Most animals exhibit external left-right (LR)-symmetric appearance and -asymmetric internal organs. A fundamental question in development is when and how ...

DOI: 10.1038/s41467-025-56115-2 Cnidarians, which include jellyfish, corals and sea anemones, are the closest living relatives of animals with bilateral symmetry, such as humans and insects.

Research into animal emotions and experience has been on the rise since the late 20th century, and scientists are beginning to use these findings to help understand an age-old question ...

These are all axisymmetrical shapes, or symmetrical around a vertical axis. Non-symmetrical shapes are more difficult, but possible; for example, the researchers sculpted a kiwi bird by allowing the ...
