在伊利诺斯大学香槟分校工作。据Schulten,这种他物是一种名为cryptochrome的尿视黄醇蛋白。
When hit by light, a cryptochrome produces pairs of molecules called free radicals that areelectrically neutral but have unpaired electrons in them.
当受到光照时,就产生名为自由基的分子对。这种自由基呈电中性,其中含有未配对电子。
Electrons are tiny magnets, so they tend to attract each other and pair up in a way thatneutralises their joint magnetic fields.
电子就是微小的磁性体。因此,当它们的联合磁场中合之时,电子就会相互吸引,就会形成组对。
Unpaired electrons, however, remain magnetic, and thus sensitive to the Earth s field.
但是,那些不成对电子仍具磁性,对地球磁场很敏感。
Moreover, because the unpaired electrons in the free radicals were originally paired in themolecule that split to form the radicals, quantum mechanics dictates that these electronsremain entangled.
因为自由基中的那些不成对电子最初存在于分裂成为自由基分子之中,量子力学规定这些电子依然是绞缠的。
This means that however far apart they move, what happens to one affects the other sbehaviour.
也就是说,无论双方离得有多远,一方的行为会影响另一方。
