Since it started orbiting Saturn last June, the Cassini mission has returned incredible images of the gas giant, its dazzling rings and its enigmatic moons. But its most dramatic chapter will come this January, when a European lander probe (Huygens) that has been piggybacking on Cassini for the last seven years is sent on a fiery plunge into the murky atmosphere of Saturns largest and most mysterious moon, Titan--a chapter that would have ended in disaster, save for an engineer called Boris Smeds.
Titan is completely covered by a thick orange smog of hydrocarbons, and scientists have speculated that oily oceans of methane and ethane may roil beneath the cloaking clouds. After slamming into the moons atmosphere at 21,000 km/hour, Huygens will take two-and-a-half hours to descend through the atmosphere, slowed by parachutes. On its way down its expected to transmit a scientific bonanza from its cameras and instruments, a bonanza that will be picked up by special radio receivers onboard Cassini and then relayed back to Earth.
But unbeknownst to anyone, a lurking flaw in Cassinis receivers meant that the data received by Cassini were going to be hopelessly scrambled. Along with his allies, ESA engineer Boris Smeds developed and championed a rigorous test that revealed the flaw and its cause in time for corrective action to be taken. Doing this required Smeds to battle bureaucracy, travel from his desk in Darmstadt, Germany, to an antenna farm deep in Californias Mojave Desert, and use all his engineering insight and creativity to expose the flaw before time ran out.

Gravitational wave kicks monster black hole out of galactic core

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.
