The Earth is a dynamic entity, and scientists are trying to understand it. Various things in nature grow and shrink, such as ice sheets, glaciers, forests, rivers, clouds and atmospheric pollutants, serving as the pulse of the planet and affecting many people in many walks of life. Scientists using NASA’s Ice, Cloud, and land Elevation Satellite (ICESat) are measuring the height of these dynamic features from space with unprecedented accuracy, providing a new way of understanding our changing planet. ICESat has lasers onboard that help it make the most accurate measurements ever.
Focus on the Freeze
Because ICESat’s unique instruments enable it to see changes in elevation, one of the areas scientists focus on are changes in the ice at the poles and in glaciers around the world. As the ICESat satellite circles the world, it sees changes in the heights of ice at the poles, and the movement of glaciers whether melting or building with snow and ice.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
