Analyzing Lake Geneva from the air
Analyzing Lake Geneva from the air
One year after the MIR submersibles dove into the depths of Lake Geneva, the elemo program is delivering its first scientific results. The operation will be extended with a campaign to make observations above the lake surface from a sensor-packed ultralight aircraft. The same experiments are planned above Lake Baikal in Russia.

X-rays provide insights into volcanic processes
X-rays provide insights into volcanic processes
Experiments investigate processes inside volcanic materials that determine whether a volcano will erupt violently or mildly. In the experiments, an international team of scientists used a laser-based heating system to heat small pieces of volcanic material similarly to conditions present at the beginning of a volcanic eruption.

Humans influencing climate since over 2000 years
Humans influencing climate since over 2000 years
New data extracted from Greenland's glaciers show that methane in the atmosphere follows the waxing and waning of civilizations. Humans have been producing substantial amounts of greenhouse gases since long before the industrial revolution 2012. By studying the tiny amounts of gases trapped in air bubbles in Greenland's glaciers, researchers have been able to add details to an emerging picture of historical human induced environmental change that reaches as far back as the Roman Empire and the Han Dynasty.

Turbulence ahead
Turbulence ahead
Although the wind may blow smoothly onto a wind turbine, it comes out the other end shredded into a complex collage of whorls, large and small. In a wind farm, the turbulent wake generated by the first row of turbines drives the turbines in the next rows, which produce up to 40% less power and suffer more from bumpier winds.

Giant telescope will reveal the outer reaches of the universe
The European Extremely Large Telescope Project (E-ELT) has officially been launched. This enormous telescope has a diameter of nearly 40m and will be built in Chili.

Science of the stick-slip
Science of the stick-slip
Scientists have succeeded in modelling what happens when two bodies slide against each other and thereby release the pressure; a discovery that has implications for the understanding of the magnitude of earthquakes. David Kammer from EPFL has developed a digital model that explains what happens at the interface between two materials when they slide against each other; like a book on a table, rubber soles on linoleum, or - more to the point - tectonic plates.
