According to the research, it is a mutual synchronization via spin wave that can be adjusted to the spin hole nano -artist.
Overview of the period between shnos and the anti -positive synchronization. Image credit: akash kumar. Spin Hall Nano Oshorator (SHNOS) is a nanoscale spintronic device that converts current directly into high -frequency microw wave signals via a spin wave auto exercise. This is a type of non -linear magnetization vibration that does not require periodic external force. Theoretical and simulation…

Survey reveals that mass die-off of seabirds due to Pacific heat wave is in full swing
A group of murres at a breeding colony in Alaska. These seabirds dive and swim underwater to prey on small fish, then fly to islands and coastal cliffs to form large colonies. Credit: Sarah Schoen/U.S. Geological Survey A common seabird, the murre looks a little like a flying penguin. These rugged, tuxedo-style birds dive or swim in the ocean to…

Unexplained heat wave “hotspots” appear around the world
Regions where observed heat waves exceed climate model trends. The darkest red boxed area is the most extreme. Less red and orange outperform the model, but not by much. The yellow almost matches the model, but the green and blue are lower than what the model projects. Credit: Kornhuber et al., taken from PNAS 2024 The hottest year on record…

Investigating the impact of ultralight dark matter on gravitational wave signals
Inspiring extreme mass ratio binaries in a dark matter environment. The movement of a small black hole creates a dense wake, which slows it down and affects the gravitational wave signal.

Researchers from the University of Adelaide have developed a new theoretical model that predicts the distances ocean waves will travel to break up sea ice. Monitoring ocean wave propagation is important for…
