Energy self-sufficient households by 2050?
Energy self-sufficient households by 2050?
Researchers from ETH Zurich investigated whether it would be technically and economically feasible for households to achieve energy self-sufficiency using photovoltaics alone in the temperate Swiss climate by the middle of the century. By 2050, photovoltaic technologies that convert sunlight into electricity could enable many singleand multi-family buildings in Switzerland to produce enough energy to meet their own consumption needs, including the charging of electric vehicles.

Directed Species Loss from Species-Rich Forests Strongly Decreases Productivity
Directed Species Loss from Species-Rich Forests Strongly Decreases Productivity
At high species richness, directed loss, but not random loss, of tree species strongly decreases forest productivity. This is shown by data from a big forest project in China in which the University of Zurich is involved. Previous studies based on random species loss could therefore bias the predictions of how more realistic extinction scenarios are likely to affect ecosystem functioning.

Hunter-Gatherer Networks Accelerated Human Evolution
Hunter-Gatherer Networks Accelerated Human Evolution
Humans began developing a complex culture as early as the Stone Age. This development was brought about by social interactions between various groups of hunters and gatherers, a UZH study has now confirmed. The researchers mapped the social networks of present-day hunter-gatherers in the Philippines and simulated the discovery of a medicinal plant product.

Tracking down the mystery of matter
Tracking down the mystery of matter
Researchers at the Paul Scherrer Institute PSI have measured a property of the neutron more precisely than ever before. In the process they found out that the elementary particle has a significantly smaller electric dipole moment than was previously assumed. With that, it has also become less likely that this dipole moment can help to explain the origin of all matter in the universe.

Tying up molecules as easily as you tie up your laces
Tying up molecules as easily as you tie up your laces
UNIGE researchers have succeeded in tying molecules together, thereby modifying their intrinsic mechanical properties. Knots are all around us: in computer cables, headphones and wires. But, although they can be a nuisance, they're also very useful when it comes to tying up your laces or when you go sailing.

Better care: fast, sensitive blood tests for use at home
Better care: fast, sensitive blood tests for use at home
They should be fast, portable and easy to use: blood tests that can be done at home. Having already come up with a prototype, ETH Pioneer Fellow Alexander Tanno is working with doctoral student Yves Blickenstorfer to bring the idea to market. The prototype that Alexander Tanno is holding between his thumb and forefinger doesn't look particularly impressive.

Investments by the super-rich drive deforestation
Wealthy individuals are increasingly investing in agriculture. Their investments boost production of plant-based raw materials for human consumption, industrial uses, and animal fodder. The resulting capital flows directly contribute to deforestation in the global South, especially in the tropics. That is the conclusion of a new study by the University of Bern's Centre for Development and Environment (CDE).

CO2 tracking in space
CO2 tracking in space
CO2 concentrations in the air continue to rise rapidly, and a rapid reduction in man-made emissions is becoming increasingly important. In order to assess the effectiveness of political measures, timely and reliable emission levels are needed. However, current methods are costly. The European Space Agency ESA is therefore working on the development of new satellites which will be able to determine CO2 emissions in the future - with the help of Empa.
