The mid-Pleistocene transition (MPT) marked a fundamental change in glacial-interglacial periodicity, when it increased from ~41,000 to 100,000 year cycles and developed higher amplitude climate variability without significant changes in the Milankovitch forcing. Here, we document, using Nd isotopes, a major disruption of the ocean thermohaline circulation (THC) system during ...

The effect of male accessory gland substances on female reproductive physiology has been previously described as "activating" egg development. However, no mechanism has been described that can explain how male mosquitoes are able to influence egg development in female mosquitoes. To investigate how male mosquitoes are able to influence ovarian ...

Trauma is usually understood as reaction to an exceptional disorganizing event. Instead, it can be recognized as the underlying fabric of everyday experience, entailing reality's fundamental unpredictability, constant change, and the inevitable erosions wrought by sickness, aging, and death. This paper draws on Ferenczi's psychoanalytic thinking to develop this view ...

Recent studies have proposed that millennial-scale reorganization of the ocean-atmosphere circulation drives increased upwelling in the Southern Ocean, leading to rising atmospheric carbon dioxide levels and ice age terminations. Southward migration of the global monsoon is thought to link the hemispheres during deglaciation, but vital evidence from the southern sector ...
