Solving a biological puzzle: How stress causes gray hair
Scientists have found evidence to support long-standing anecdotes that stress causes hair graying. Researchers found that in mice, the type of nerve involved in the fight-or-flight response causes permanent damage to the pigment-regenerating stem cells in the hair follicle. The findings advance knowledge of how stress impacts the body, and are a first step toward blocking its negative effects.

Atmospheric CO2 levels from 2.7 billion years ago inferred from micrometeorite oxidation
Earth's atmospheric composition during the Archean eon of 4 to 2.5 billion years ago has few constraints. However, the geochemistry of recently discovered iron-rich micrometeorites from 2.7 billion–year–old limestones could serve as a proxy for ancient gas concentrations. When micrometeorites entered the atmosphere, they melted and preserved a record of atmospheric interaction. We model the motio

Seismic evidence for megathrust fault-valve behavior during episodic tremor and slip
Fault slip behavior during episodic tremor and slow slip (ETS) events, which occur at the deep extension of subduction zone megathrust faults, is believed to be related to cyclic fluid processes that necessitate fluctuations in pore-fluid pressures. In most subduction zones, a layer of anomalously low seismic wave velocities [low-velocity layer (LVL)] is observed in the vicinity of ETS and sugges

CagA-ASPP2 complex mediates loss of cell polarity and favors H. pylori colonization of human gastric organoids [Microbiology]
The main risk factor for stomach cancer, the third most common cause of cancer death worldwide, is infection with Helicobacter pylori bacterial strains that inject cytotoxin-associated gene A (CagA). As the first described bacterial oncoprotein, CagA causes gastric epithelial cell transformation by promoting an epithelial-to-mesenchymal transition (EMT)-like phenotype that disrupts…

Chlamydia-induced curvature of the host-cell plasma membrane is required for infection [Microbiology]

We show here that the strongly amphipathic N-terminal helix of CPn0678 mediates binding…
