A new crew of three astronauts are launching to the International Space Station late tonight, blasting off on a Russian Soyuz rocket out of Kazakhstan. The trio are heading to the station about a month ahead of SpaceX’s next crewed Dragon launch, which will bring another set of four astronauts aboard the ISS in mid-November.
Heading up on this Soyuz flight are two Russian cosmonauts — Sergey Ryzhikov and Sergey Kud-Sverchkov — and NASA astronaut Kate Rubins, on her second trip to space. The trio will join three crew members who have been living on the ISS since April: Russian cosmonauts Anatoly Ivanishin and Ivan Vagner and NASA astronaut Chris Cassidy. However, their living arrangement won’t last long. Cassidy and his cosmonaut crew mates are slated to head back to Earth on October 21st, riding inside the Soyuz capsule that brought them to the space station.

The summer of 2020 was supposed to be one of exploration, discovery, and mentorship for students in the geosciences.
But then the pandemic happened.
Laboratories shuttered their doors; research vessels stayed docked.
Many of the mentorship programs students applied to are now navigating the still-uncharted waters of the “new normal” and working to provide quality, albeit remote, mentorship.
STEMSEAS—short for Science, Technology, Engineering and Math Student Experiences Aboard Ships—is one such program.
Run out of the Lamont-Doherty Earth Observatory at Columbia University, the National Science Foundation–funded initiative has been a gateway for more than 125 students to experience ocean science up close every summer since 2016. In a normal year, STEMSEAS gives undergraduates the opportunity to spend 6–10 days aboard a U.S. Academic Research Fleet research vessel with experienced faculty mentors as the ship makes transits between expeditions.

New research published in EPJ B reveals that the nature of the boundary at which an antiferromagnet transitions to a state of disorder slightly depends on the geometry of its lattice arrangement.

Calculations involving ‘imaginary’ magnetic fields show how the transitioning behaviours of antiferromagnets are subtly shaped by their lattice arrangements.
Antiferromagnets contain orderly lattices of atoms and molecules, whose magnetic moments are always pointed in exactly opposite directions to those of their neighbours.
These materials are driven to transition to other, more disorderly quantum states of matter, or ‘phases,’ by the quantum fluctuations of their atoms and molecules — but so far, the precise nature of this process hasn’t been fully explored. Through new research published in EPJ B, Yoshihiro Nishiyama at Okayama University in Japan has found that the nature of the boundary at which this transition occurs depends on the geometry of an antiferromagnet’s lattice arrangement.
