Rose pangenome maps 55,000 genes, opening new path for breeding

Roses are among the most economically significant ornamental plants worldwide, with widespread applications in the cut flowers, garden, and cosmetics industries. Yet fewer than 10% of rose species have contributed to modern cultivated roses. Until recently, available technologies did not allow to fully sequence the Rosa subgenus.

Collagen analysis finds wider prey use by Neanderthals and modern humans

The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has taken part in a study published in the International Journal of Osteoarchaeology that provides new insights into subsistence strategies during the Middle to Upper Paleolithic at the site of Cova Eirós (Cancelo, Triacastela, Lugo). The research applies a collagen-based approach to improve the taxonomic identification of faunal remains.

Cell membranes may store memories after electrical stimulation

The science of memories has been pursued and studied since the days of ancient Greece and Aristotle. Today, research conducted by Dima Bolmatov, assistant professor in the Department of Physics & Astronomy at Texas Tech University, is considering how memories are stored on a cellular level.

Penguin muscle map reveals how waddles and underwater 'flight' both work

Penguins may look charmingly awkward on land, but new research shows their bodies are finely tuned for powerful, efficient movement both on land and underwater. A team of anatomists from Midwestern University, in collaboration with SeaWorld San Diego and Scarlet Imaging, has published a detailed study of the limb musculature of the macaroni penguin (Eudyptes chrysolophus), uncovering previously unknown features that help explain how these birds swim, dive, and even stand upright.
