Many predatory fishes hunt and feed in structurally complex environments making their feeding behaviors challenging to observe. We designed a transparent microhabitat to document how the California moray ( Gymnothorax mordax ) uses its elongated body to apply leverage during crevice foraging within the rocky reef. To generate leverage, these predatory fish use complex behaviors to extract prey from tight spaces. Morays form an...

The negative and cognitive symptoms of schizophrenia are predictive of quality of life and functional recovery, but there are no approved drug options that target these symptoms directly. TAK-041 (also known as NBI-1065846) is a selective and potent small-molecule agonist of GPR139, an orphan G-protein-coupled receptor, which has been shown to reverse deficits related to negative and cognitive symptoms in animal models. In thi...

Some bacteria genetically control the biomineralisation of intracellular amorphous calcium carbonates (iACC) with potential implications for microbial physiology, evolution, bioremediation and biogeochemical cycling. Until now, this capacity has been documented in Cyanobacteria , the giant gammaproteobacterium Achromatium and a few magnetotactic Pseudomonadota and Nitrospirota . Here, we report the discovery of iACC biomineral...

Background Major depressive disorder (MDD) is a common and serious psychiatric disorder associated with significant morbidity. There is mounting evidence for the role of oxidative stress in the pathophysiology of depression. Objective To investigate alterations in the brain antioxidant glutathione in depression by undertaking a meta-analysis of proton magnetic resonance spectroscopy (1H-MRS). Methods MEDLINE, EMBASE and Psych...
