Extraterrestrial life may look nothing like life on Earth − so astrobiologists are coming up with a framework to study how complex systems evolve

A specific set of chemical conditions led to the emergence of life on Earth. But can life emerge from other chemistries?

Towards a molecular picture of the archaeal cell surface - Nature Communications

The model archaeon Sulfolobus acidocaldarius produces several protein filaments with specialised functions, including flagellum-like archaella, Aap pili, and adhesive threads. Here, the authors describe high-resolution structures and distinct glycosylation patterns for the three filaments, and present an integrated model of the filaments in the context of the S-layer.

Carl Sagan’s scientific legacy extends far beyond ‘Cosmos’

On what would’ve been the astronomer’s 90th trip around the Sun, here’s a look at his legacy as a scientist, advocate and communicator.

Biomedical researchers’ perspectives on the reproducibility of research

There is growing interest in the reproducibility of research and ways to enhance transparency. This study uses an international survey of more than 1900 biomedical researchers to reveal the perceived causes of irreproducibility of research results, experience of conducting replication studies, and knowledge of relevant funding and training.
