Scientists who just months ago confirmed that Earth’s inner core recently reversed its spin have a new revelation about our ...

Shear waves, or S waves, are slower than P waves and move the ground perpendicular to the wave’s direction. Amplitude changes in a type of core-penetrating P wave — PKIKP waves — hinted at ...

The retrospective study population included 61 patients (29 men) with a mean age of 42 ± 5 years. Echocardiography showed normal LA (33.4 ± 1.5 mm) and normal ejection fraction (63.1 ± 2.3%).
