🐦🧭 A team at the University of #Bonn found that #pigeons rely on iron-rich #macrophages in their livers to sense #Earth’s magnetic fields.
When researchers deactivated these #cells, the #birds lost their way on overcast days – but navigated fine under sunny skies, confirming a backup magnetic system that kicks in when visual cues aren’t available.

How pigeons exploit magnetic fields for navigation
Iron-rich immune cells in the liver may act as sensors for magnetic fields, serving as an internal compass.
🪨🔥 #Earth’s inner core reaches about 5,500°C, roughly as hot as the surface of the #sun.
Scientists from UC #SantaCruz and Sun Yat-sen University calculated this using diamond anvil cells and shock-wave experiments that simulate the extreme pressures deep underground. The outer core’s liquid #iron also generates #Earth’s magnetic field, which protects all #life from #solar #radiation.

Astronomers Discover Unexpected Magnetic Reversal in the Milky Way's Sagittarius Arm
Researchers at the University of Calgary have uncovered a previously hidden magnetic structure within the Milky Way, revealing a diagonal magnetic field reversal in the Sagittarius Arm. Utilizing the Dominion Radio Astrophysical Observatory’s new radio telescope, part of the Global Magneto-Ionic Medium Survey (GMIMS), the team produced one of the most detailed maps of the galaxy's magnetic field to date. By measuring Faraday rotation, an effect in which radio waves are altered by electrons and magnetic fields, scientists were able to trace complex magnetic patterns across vast distances. The discovery of a counterclockwise magnetic region within an otherwise clockwise field challenges existing models of galactic structure and could reshape our understanding of how magnetic fields influence the stability and evolution of the Milky Way. Lead researchers Dr. Jo-Anne Brown, Dr. Anna Ordog, and PhD candidate Rebecca Booth published their findings in The Astrophysical Journal and its Supplement Series, introducing a three-dimensional model of the magnetic reversal. This work provides a critical resource for astronomers worldwide to refine simulations of the galaxy and study the role of magnetism in galactic dynamics. The new dataset and models are expected to impact future studies on galactic evolution and interstellar magnetic phenomena.
