Imagine a space tool so revolutionary it can determine the impact of climate change, monitor the melting of glaciers, discover invisible waves, predict the strength of hurricanes, conserve fish stocks and measure river and lake levels worldwide, among other scientific applications. This instrument is not the subject of a science-fiction novel. In fact, four of them are already operating 800 kilometres above Earth.
Fifteen years ago this ground-breaking instrument, called a radar altimeter, was launched into orbit, despite speculation of its usefulness from the wider oceanographic community. Although it took over a decade for its full impact to be realised, its accomplishments have been so great that it is credited with having revolutionised the field of physical oceanography.
In honour of altimetry, oceanographers, glaciologists, hydrologists and geodesists from around the world have gathered in Venice Lido, Italy, at the ‘15 Years of Progress in Radar Altimetry’ symposium, organised by ESA and the French Space Agency (CNES), to celebrate its success. Signifying its vast array of achievements, many have come to honour it for different reasons.

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
