Building blocks of language evolved 30-40 million years ago

The capacity for language is built upon our ability to understand combinations of words and the relationships between them, but the evolutionary history of this ability is little understood. Now, researchers from the University ...

Transcription factors may inadvertently lock in DNA mistakes

Transcription factor proteins are the light switches of the human genome. By binding to DNA, they help turn genes 'on' or 'off' and start the important process of copying DNA into an RNA template that acts as a blueprint ...

Coronaviruses are masters of mimicry, new study finds

Coronaviruses are adept at imitating human immune proteins that have been implicated in severe COVID-19 disease, a study from researchers at Columbia University Vagelos College of Physicians and Surgeons has found.

Most migratory birds rely on a greening world, study finds

A new study from the Cornell Lab of Ornithology confirms that most birds—but not all—synchronize their migratory movements with seasonal changes in vegetation greenness. This is the first study of its kind to cover the ...

Butterfly color diversity due to female preferences

Butterflies have long captured our attention due to their amazing color diversity. But why are they so colorful? A new publication led by researchers from Sweden and Germany suggests that female influence butterfly color ...

The sweet spot of flagellar assembly

To build the machinery that enables bacteria to swim, over 50 proteins have to be assembled according to a logical and well-defined order to form the flagellum, the cellular equivalent of an offshore engine of a boat. To ...
