First images of the Sun's south pole!
Solar Orbiter is the first space probe to look at the Sun's poles – and finds the magnetic field there in a state of turmoil. The Sun's magnetic field is currently undergoing a flip. During its latest flyby of the Sun at the end of March this year, the Solar Orbiter space probe had its first clear view of our star's poles. First images:

This image shows a magnetic field map from Solar Orbiter's Polarimetric and Helioseismic Imager (PHI) instrument, centred on the Sun's south pole. Blue indicates positive magnetic field, pointing towards the spacecraft, and red indicates negative magnetic field. On an off-set concentric grid with an overall yellow base color, blue and red bent stripe-like structures are sprinkled across the field of view. © ESA & NASA/Solar Orbiter/PHI Team, J.

First images of the Sun's south pole
During its latest flyby of the Sun at the end of March this year, the Solar Orbiter space probe had its first clear view of our star's poles. The first images and observational data from the south pole taken during this flyby were published today. The solar poles are largely unexplored; no space probe has ever seen them before. Solar Orbiter's trajectory has recently been tilted 17 degrees relative to the Sun's equator, allowing measurements from this unique perspective for the first time. The …

Magnetophoresis of Weakly Magnetic Nanoparticle Suspension Around a Wire
We present a combined experimental and numerical study into the magnetophoresis behavior of weakly magnetic nanoparticle suspensions in the vicinity of a wire under a non-uniform magnetic field and negligible inertia. The experiments were conducted within a closed rectangular cuvette, with a wire positioned between the poles of an electromagnet. Two types of nanoparticles, paramagnetic manganese oxide and diamagnetic bismuth oxide, were studied across a broad range of concentrations (10-100 mgL…

Was der Spiegel zum Sudhof-Bericht und zu Spahn schreibt, ist ziemlich harter Tobak - aber dieser Typus "Macher, der fachlichen Rat ignoriert und lieber auf Beziehungen setzt" scheint in der Union leider nicht selten zu sein.

Spahns Maskendeals: »Jetzt will ich rechtlich verbindlich das Zeug ;-)«
Der Sonderbericht zu den Maskengeschäften wird für Jens Spahn mit jeder Enthüllung gefährlicher. Nun geht es um hemdsärmlige Mails, die Deutschland Hunderte Millionen kosten könnten.

It does say something about the sheer magnitude of the No Kings protests that we could for a moment believe the photo was in fact from yesterday.

This man has been a legal permanent resident of the United States for 10 years. He was at his interview to finalize his US citizenship when he was instead carried away in handcuffs to an unknown location.
None of his friends or family knows where he has been taken.
He has been charged with no crime.
