Methylation pace of aging is a novel measure requiring only a blood sample that clinical-trial and observational studies can use to test if treatments modify how fast participants are aging.
Two cellular populations can be tracked in the same small animal model using near-infrared bioluminescence imaging, for the first time opening up the window for multi-coloured bioluminescence.
Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.
Using noise suppression, real-time imaging of glucose metabolism is possible by 13C MRI and reveals previously undetected metabolic differences within tumors.
Direct reprogramming of smooth muscle cells from HGPS patients revealed that BMP4 is a key contributor of vascular degeneration and might represent a new therapeutic target.
Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.
The first non-invasive technique to assess the action of brain clearance mechanisms, driven by the perivascular inflow of cerebrospinal fluid, has been developed using magnetic resonance imaging.
A new platform for imaging live Drosophila adults yields vivid movies of the midgut over prolonged time scales, opening the door to the real-time study of organ renewal dynamics in a near-native context.
