IPTF14hls may be a variable hyper-wind from a very massive star, study suggests

A source known as iPTF14hls, assumed to be a Type IIP supernova, may be a long-term outflow similar to stellar winds, according to a new study published November 5 on arXiv.org. The new research proposes that iPTF14hls is ...

Dung beetle discovery revises biologists' understanding of how nature innovates

When studying how organisms evolve, biologists consider most traits, or features, as derived from some earlier version already present in their ancestors. Few traits are regarded as truly "novel."

How gene expression noise shapes cell fate

Essential genes are often expressed with high variability during the development of cells. Scientists call this phenomenon "biological noise" and suspect that it is also decisive for the fate of cells, i.e. the developmental ...
