Does The Ocean Lose Its Breath?

The ocean takes a deep breath.

Deep convection is the major mechanism for replenishing oxygen in the deep interior of the world ocean, and its variability affects the use of atmospheric oxygen to monitor the global carbon cycle. Sensors mounted on autonomous floats allow this episodic breathing of the ocean to be monitored in near real time. The results suggest that the tools are available now to make oxygen a key parameter ...

How does silicon lead the kinetics of the galvanizing reaction to lose its solid-solid character

How Does a Dication Lose a Proton?

A detailed study of the mechanism by which a proton is lost from a dication reveals that such processes are more complicated than is often assumed. In many cases, a deprotonation reaction is best viewed as a two-stage process: Initially, the departing unit is better described as a hydrogen atom than as a proton and only later, at some point further along the decomposition pathway, does a sponta...

MDGAs help the brain lose its inhibitions

MDGAs help the brain lose its inhibitions S ynapse development is promoted by a variety of cell adhesion molecules that connect neurons and organize synaptic proteins. Many of these adhesion molecules are linked to neuro-developmental disorders; mutations in neu-roligin and neurexin family members, for example, are associated with autism and schizophrenia. Pettem et al. reveal that another fami...

Does richness lose its luster? Effects of extensive practice on semantic richness in visual word recognition

Previous studies have reported facilitatory effects of semantic richness on word recognition (e.g., Yap et al., 2012). These effects suggest that word meaning is an important contributor to lexical decision task (LDT) performance, but what are the effects of repeated LDT practice on these semantic contributions? The current study utilized data from the British Lexicon Project (BLP) in which 78 ...
