WebDec 1, 1998 · Modern versions of the geomagnetic polarity timescale (GPTS) show cryptochrons, small-scale magnetic intervals of less than 30 kyr duration (e.g. Harland et al. 1982, 1989; Cande & Kent 1992, 1995 ), which had been recognized as ‘tiny wiggles’ in numerous marine magnetic profiles ( Blakely 1974 ). WebApr 8, 2024 · Long before we knew birds could 'see' Earth's magnetic field, Albert Einstein discussed the possibility of animals with super senses in his fan mail to other researchers. A long-lost letter from the scientist to an inquiring engineer in 1949 turned out to be extraordinarily prescient in the fields of biology and physics.
