The raucous calls of tree hyraxes — small, herbivorous mammals — reverberate through the night in the forests of West and Central Africa, but their sound differs depending on the location. Tree hyraxes living between the Volta and Niger rivers make a barking call that is distinct from the shrieking […]

In a paper published in Science, biologists at Baylor College of Medicine, the Netherlands Cancer Institute and Rice University studying the tree of life unveil a new classification system for cell nuclei and the discovery of a method for transmuting one type of cell nucleus into another. This illustration shows […]

In recent years, advancements in DNA sequencing have exposed a large amount of hidden diversity in reef-building […]

Māori wrasse are large, colorful fish that can be found on the Great Barrier Reef. In a ground-breaking new study, scientists used innovative molecular techniques to explain how corals on the east coast of Australia survived previous tough conditions—enabling the Great Barrier Reef to become the vast reef it is […]

Linum bienne is the closest relative to cultivated flax.

The new checklist, which was published […]

Using computer simulations built on reasonable assumptions and conducted under careful control, computational bioscientists can mimic real biological conditions. Starting with the original founding population (ancient phase), they can evolve the population over several thousand generations to develop an intermediate phase, and then evolve that generation another several thousand generations […]

The banyan tree Ficus macrocarpa produces aerial roots that give it its distinctive look. A new study reveals the genomic changes that allow the tree to produce roots that spring from its branches. Credit: Photo by Gang Wang The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout […]

Newly described chemical reaction could have assembled DNA building blocks before life forms and their enzymes existed.   ANIMATION Discovery boosts theory that life on our planet arose from RNA-DNA mix. Chemists at Scripps Research have made a discovery that supports a surprising new view of how life originated on our […]
