A team from the University of Geneva studied the ash from volcanic eruptions and discovered two effects of ash sedimentation that will improve our ability to predict the danger posed by volcanic ash clouds.

Energy management in a house with a solar system is becoming increasingly complex: When do I turn on the heating so that it is nice and cosy in the evening? How much electricity can the hot water tank hold? Will there still be enough energy for the electric car? Artificial Intelligence (AI) can help solve the problem: Researchers at Empa developed an AI control system that can learn all these tasks - and save more than 25 percent energy in the process.

Until now, researchers have found no evidence of global tectonic activity on planets outside our solar system. Under the leadership of the University of Bern and the National Center of Competence in Research NCCR PlanetS, scientists have now found that the material inside planet LHS 3844b flows from one hemisphere to the other and could be responsible for numerous volcanic eruptions on one side of the planet.

In Lake Constance, sticklebacks are occupying increasingly varied habitat types - in recent years even including the open and deep waters of the lake. In an Eawag review undertaken as part of the "SeeWandel" project, these uniquely diverse ecological adaptations are explained in terms of renewed contact between three stickleback lineages - including one originating from the Baltic region, whose genetic material is as yet rarely observed in other Swiss lakes.
