The sun may have started its life with a binary companion

A new theory published today in the Astrophysical Journal Letters by scientists from Harvard University suggests that the sun may once have had a binary companion of similar mass. If confirmed, the presence of an early stellar ...

How to improve climate modeling and prediction

We are changing the Earth system at a unprecedented speed without knowing the consequences in detail. Increasingly detailed, physics-based models are improving steadily, but an in-depth understanding of persisting uncertainties ...

Human embryo-like model created from human stem cells

Scientists from the University of Cambridge, in collaboration with the Hubrecht Institute in The Netherlands, have developed a new model to study an early stage of human development, using human embryonic stem cells. The ...
