Feathered feet of pigeons and chickens result from a partial molecular and morphological transformation of legs to a wing-like identity.

Non-imprinted genes can contribute to parent-of-origin effects on phenotype through interactions with imprinted genes.

Flowers of different plant species show distinct and highly diverse patterns of temperature across their surfaces, and bumblebees are able to differentiate between these previously unnoticed but widespread floral cues.

Despite having different shapes and structures, the melanosomes (melanin-packed organelles) in bird feathers often produce thin melanin layers, giving rise to brilliant iridescence.

A sudden fall in the levels of the coenzyme NADPH within cells could have a central role in the process of aging.

Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.

Cation chloride cotransporter CCC1 has a central function in plant cells and is the missing ion efflux component of the transport circuit necessary to regulate pH in the lumen of the trans-Golgi-network/early endosome, the major cargo hub in plant cells.

Structural and biochemical analyses of a eukaryotic DNA transpososome in the integration step reveal how mariner/Tc1 transposons are selectively integrated into a TA target sequence.

Selfee, a self-supervised learning approach, is designed to extract comprehensive and discriminative features directly from raw videos of animal behaviors which can be used for in-depth analysis.

Social-affective features predict the perceived similarity of real-world actions better than, and independently of, visual and action-related features, and are extracted at the final stage of a temporal gradient in the brain.
