New theoretical model accounts for sun's rotation and magnetic field

In the early 2000s, a new set of data revised the chemical abundances at the surface of the sun, contradicting the values predicted by the standard models used by astrophysicists. Often challenged, these new abundances made it through several new analyses. As they seemed to prove correct, it was thus up to the solar models to adapt, especially since they serve as a reference for the study of stars in general. A team of astronomers from the University of Geneva, Switzerland (UNIGE) in collaboration with the Université de Liège, has developed a new theoretical model that solves part of the problem: considering the sun's rotation, that varied through time, and the magnetic fields it generates, they have been able to explain the chemical structure of the sun. The results of this study are published in Nature Astronomy.

New artificial enzyme breaks down tough, woody lignin: Study shows promise for developing a new renewable energy source

A new artificial enzyme has shown it can chew through lignin, the tough polymer that helps woody plants hold their shape. Lignin also stores tremendous potential for renewable energy and materials.

Big tobacco's environmental impact is 'devastating': WHO

The tobacco industry is a far greater threat than many realise as it is one of the world's biggest polluters, from leaving mountains of waste to driving global warming, the WHO charged Tuesday.
