Elephants as a new model for understanding human evolution      (via sciencedaily.com)     Original source 

Human culture and language may be the result of 'self-domestication': an evolutionary process that leads to less aggressive and more prosocial individuals. A research team argues that elephants -- like humans and bonobos -- may also be self-domesticated. Elephants show many traits associated with self-domestication, such as prosocial behavior, playfulness and complex communication skills. This makes elephants an interesting new animal model for the evolution of prosociality.

One of Swedish warship Vasa's crew was a woman      (via sciencedaily.com) 

When the human remains found on board the Swedish warship Vasa (1628) were investigated, it was determined that the skeleton designated G was a man. New research now shows that the skeleton is actually from a woman. About thirty people died when Vasa sank on its maiden voyage in Stockholm, 1628. We cannot know who most of them were, only one person is named in the written sources. When the ship was raised in 1961 it was the scene of a comprehensive archaeological excavation, in which numerous human bones were found on board and examined.

AI predicts enzyme function better than leading tools      (via sciencedaily.com)     Original source 

A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. Researchers said the AI tool, dubbed CLEAN, outperforms the leading state-of-the-art tools in accuracy, reliability and sensitivity. Better understanding of enzymes and their functions would be a boon for research in genomics, chemistry, industrial materials, medicine, pharmaceuticals and more.

Chemists design new molecule, with oxygen as the star of the show      (via sciencedaily.com) 

Chemists have achieved a new feat in the realm of chemical design and synthesis: They've helped create the first example of a synthetic molecule, with an asymmetric oxygen atom as its centerpiece, that remains stable and nonreactive -- despite this type of molecule's tendency in nature to be touchy and short-lived. What makes this feat unique is that the new molecule is chiral, which means it has a non-superimposable mirror image.
