How to Watch the Electron Dance in Living Cells ⚡ экспресс
Inside our cells, reactions take place with radical pairs—molecules sensitive to magnetic fields, like tiny compasses. Previously, they couldn't be seen because they don't glow. Scientists came up with two new microscopy methods using light pulses that made these reactions 'light up.' This opens a window into the quantum world of the living cell. What other secrets does our body hide?
Inside every living cell, chemical transformations are constantly taking place. Some of them create unstable particles whose electrons behave like paired magnets. Their interaction resembles a dance: each movement of the pair responds to external magnetic fields, as if to a changing rhythm.
The invisibility of this dance prevented us from seeing it directly. Now scientists illuminate the cell with a pair of ultrashort laser flashes. The first sparks the dancers into motion; the second, arriving precisely an instant later, makes the reaction products glow. By analyzing the change in brightness of this glow, they reconstruct each 'step,' revealing a picture of the chemistry of magnetic interactions.
The method was tested on cells containing a magnetism-sensitive molecule. The same principle explains the navigation of migratory birds: their visual cells capture the electron dance, translating Earth's magnetic field into tangible images. In the future: portable sensors and therapies controlled by weak magnetic pulses.
🎯 Migratory birds use this same mechanism: their eyes capture the electron dance, turning Earth's magnetic field into visual cues.
