Solar and wind energy may stabilise the power grid

https://www.mpg.de/6351135/power-grid-regenerative-energy

A decentralized power grid with many small wind generators, solar generators and other renewable energy transducers along with additional power lines may be less vulnerable to outages than a centralized power grid with a small number of large power plants, because self-synchronization occurs in the former. This finding was made through simulations performed by the research team led by M. Timme at the Max Planck Institute for Dynamics and Self-Organisation. However, they found that it is important for grid stability that new lines are planned with care in order to avoid Braess’s Paradox.

How gas clouds fragment and form the biggest stars

Using the ALMA observatory in Chile, a group of astronomers led by MPIA’s Henrik Beuther has made the most detailed observation yet of the way that a giant gas cloud fragments into dense cores, which then act as the birthplaces of stars. The astronomers found that the mechanisms for fragmentation are fairly straightforward, resulting from the combination of the cloud’s pressure and gravity. More complex features, such as magnetic lines or turbulence, play a smaller role than previously thought.
It probably has evolved in the same way as the one just forming in G351.77-0.54,
