NASA's Webb telescope: Engineered to endure micrometeoroid impacts

Micrometeoroid strikes are an unavoidable aspect of operating any spacecraft, which routinely sustain many impacts over the course of long and productive science missions in space. Between May 23 and 25, NASA's James Webb Space Telescope sustained an impact to one of its primary mirror segments. After initial assessments, the team found the telescope is still performing at a level that exceeds all...

New insights into neutron star matter

An international research team has for the first time combined data from heavy-ion experiments, gravitational wave measurements and other astronomical observations using advanced theoretical modeling to more precisely constrain the properties of nuclear matter as it can be found in the interior of neutron stars. The results were published in the journal Nature.

Investigating the magnetic properties of helium-3

In a joint experimental-theoretical study published in Nature, physicists at the Heidelberg Max Planck Institute for Nuclear Physics (MPIK), together with collaborators from RIKEN, Japan, investigated the magnetic properties of the isotope helium-3. For the first time, the electronic and nuclear g-factors of the 3He+ ion were measured directly with a relative precision of 10–10. The...

Rental seekers with foreign-sounding names get fewer callbacks from landlords: study

In Sweden, a study that sent fictitious applications in response to real housing ads has found that male applicants with foreign-sounding names received fewer callbacks than male applicants with a name that signals Swedish ethnicity. Hemrin Molla and colleagues at the University of Gothenburg, Sweden, present these findings in the open-access journal PLOS ONE on June 8, 2022.

Air pollution may increase freezing rain in northern hemisphere

Freezing rain is a typical weather disaster in winter and early spring over many regions of the world, even tropical areas. It develops as supercooled water (below 0 °C) in the air and freezes immediately after depositing on cold surfaces. In southern China, freezing rain mainly happens in the mountainous areas.
