Observing the birth of a quasiparticle
Over the past decades, physicists worldwide have been trying to gain a better understanding of non-equilibrium dynamics in quantum many-body systems. Some studies investigated what are known as quasiparticles, disturbances or entities in physical sys.....»»
Declining fertility ideals? Young people more often prefer having no children
Fertility has declined in high-income countries over the last decade, but has the number of children people wish to have also declined? A recent study shows that the ideal number of children has decreased across birth cohorts, especially among people.....»»

New image reveals secrets of planet birth
A spectacular new image released today by the European Southern Observatory gives us clues about how planets as massive as Jupiter could form. Using ESO's Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA), researc.....»»
A tailor-made magnetic vortex: A closer look at a special kind of quasiparticle
Skyrmions are microscopic magnetic vortices that can form in certain materials. First detected in 2009, they are of interest to researchers because they could be harnessed for new forms of data storage. As theoreticians predicted, there are also so-c.....»»
