Retracing parts of Darwin’s Beagle voyage

https://www.mpg.de/18264873/on-the-trail-of-charles-darwin

On 12 February 2022, Charles Darwin would have been 213 years old. In honour of the British naturalist, the international Darwin Day will be celebrated worldwide tomorrow. One person who recently sailed in Darwin’s footsteps is Eduardo Sampaio from the MPI of Animal Behavior in Constance. He spent ten days on board the Captain Darwin in the waters off Cape Verde – almost 200 years after Charles Darwin visited the islands off the West African coast.
The 12-metre sailing boat takes the same route as the HMS Beagle did back then.

Solar and wind energy may stabilise the power grid

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.
