Membrane Interactions
Membrane proteins and membrane interactions of proteins are studied by spin label EPR. Intact, native membranes, vesicles of all sizes and nano-disks can be investigated, because the size of the object does not matter in EPR. Whereas solution NMR is limited to micelles (a few nm in diameter), by EPR…

Giant rings orbit wrong way around exoplanet
Researchers from Japan and the Netherlands who were previously involved in the discovery of an exoplanet with huge rings have now calculated that the giant rings may persist more than 100,000 years, as long as the rings orbit in the opposite direction to that of the planet around the star. Their findings…

Giant cosmic tsunami wakes up comatose galaxies
Galaxies are often found in clusters, which contain many “red and dead” members that stopped forming stars in the distant past. Now, an international team of astronomers, led by Andra Stroe of Leiden Observatory and David Sobral of Leiden and the University of Lisbon, has discovered that these comatose…

Giant galaxies grow out of cold cosmic oceans
The largest galaxies in the Universe feed off cosmic oceans, which helps them grow. This is the presumption of an international team of scientist with two Leiden astronomers, based on observations of the ‘Spiderweb’ galaxy. The researchers published their evidence in Science on 2 December 2016.

Astronomy student searches for giant rings with pictures from 1890
Meticulous analysis of hundreds of photographic plates from the star J1407 between 1890 and 2007 show no stellar eclipses. Robin Mentel, a master student at Leiden University, could not detect eclipses of the star J1407 by a planet hypothesized to have giant rings, called J1407b. However, an eclipse…

Giant planet at large distance from sun-like star puzzles astronomers
A team of astronomers led by Dutch scientists have directly imaged a giant planet orbiting at a large distance around a sun-like star. Why this planet is so massive, and how it got to be there, is still a mystery. The researchers will publish their findings in the journal Astronomy & Astrophysics.

LOFAR antennas unveil giant glow of radio emission surrounding cluster of galaxies
A Dutch-Italian-German team of astronomers has observed a huge glow of radio emission around a cluster of thousands of galaxies. They combined data from thousands of LOFAR antennas that were focused for 18 nights on an area the size of four full moons. This is the first time astronomers have been able…
