The CryoSat validation programme took another important step forward on Wednesday with the official handover of a unique set of data that had been collected by the intrepid Dutch Polar Explorer Marc Cornelissen on behalf of ESA during his recent expedition to the North Pole.
In March this year, Marc Cornelissen left Cape Arctichesky in northern Russia to lead the Pole Track 2005 expedition on a 1,000 km ski trek to the geographic North Pole. Along the way, the expedition team deployed mobile weather stations to transmit meteorological data, and collected a valuable set of snow depth measurements following a protocol that had been developed with ESA.
"While snow depth information holds the key to producing accurate maps of ice-thickness change over time with CryoSat, there are surprisingly few of these basic measurements readily available," says Malcolm Davidson, ESA CryoSat Validation Manager. "As a rule, people dont spontaneously spend weeks on end on the ice measuring this parameter. Marc Cornelissens careful measurements of snow thickness during his expedition are thus very valuable indeed. The data will now be analysed by scientists participating in ESAs CryoSat calibration and validation programme."

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
