Fluorescence imaging can be conducted with long Stokes shift dyes that minimize crosstalk between the excitation source and fluorescent emission to improve the signal-to-background ratio. Regardless, researchers still form ...
Scientists have long debated the origins of teeth. Did they evolve from body scales that migrated into the mouths of ancient vertebrates and became adapted for eating—an idea known as the "outside-in" hypothesis? Or did ...
Big bones from the extinct "thunder bird" or dromornithid, excavated in the northern reaches of the Flinders Ranges and near Alice Springs, have yielded new insights into their slow breeding patterns.
Lungs are essential to many vertebrates including humans. However, four living amphibian clades have independently eliminated pulmonary respiration and lack lungs, breathing primarily through their wet skin. Little is known ...
Researchers at Kanazawa University report in Communications Biology that using common chemicals for fixing living cell samples for microscopy studies causes membrane proteins to aggregate.
Studying evolution by focusing solely on fossils would leave many questions unanswered, but evolutionary developmental biology (otherwise known as "evo-devo") helps fill in the gaps.
In a study published in Nature Methods, a research team led by Prof. Qu Kun from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has benchmarked 16 spatial and single-cell transcriptomics ...
With rare exceptions, each of the trillions of cells in our bodies carries an exact duplicate of the human genome, which contains between 20,000 and 25,000 protein-coding genes. But to carry out the specialized functions ...
Scientists from St Petersburg University, together with colleagues from Tomsk and Novosibirsk, have discovered a new species of soil amoeba Leptomyxa silvatica n. sp. in Chernevaya taiga located in the south of Western Siberia.
Cytochrome P450, family 17, subfamily A, polypeptide 1 (cyp17a1) is a critical enzyme involved in gonadal steroidogenesis, including androgen and estrogen production. Among sex steroids, androgen signaling disruption is known ...
