🐦🧭 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.

How hot is Earth's core?

What's the temperature in Earth's core, and how did we figure that out?

Astronomers Discover Unexpected Magnetic Reversal in the Milky Way's Sagittarius Arm

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.

600 million years ago, Earth’s magnetic field shifted wildly during the Ediacaran Period. 🧭
New research reveals the chaos followed an organised global pattern, not random fluctuations.
This breakthrough could finally unlock accurate maps of ancient continents. #Geology #MagneticField #EarthHistory

@ShutterRatata great photo.#Robins (#Erithacus #rubecula, #Muscicapidae) are endearing to us, partly due to their short #flightdistance. Combined with their attractive #appearance, they evoke positive associations in us. Therefore, they e.g. play a role in #culturaltraditions (Christian legends).They have twice been #BirdoftheYear in Germany. In 1963, robins were the first animal, in which the presence of a #magneticsense (#orientation via Earth's #magneticfield) was proven. Text: S.F.Wirth
