Testosterone modulates multispectral oscillatory activity serving performance of motor sequences in typically developing youth

The Journal of Physiology, Volume 604, Issue 7, Page 3114-3134, 1 April 2026.
Abstract figure legend Increases in testosterone are associated with developmental changes in motor‐related neural oscillations in youth. Abstract Motor control is critical to daily functioning and undergoes significant refinement throughout youth. Although the effects of age on the underlying brain circuitry have been well characterized, fewer studies

Frequency‐Resolved Cortical Functional Connectivity Across the Adult Lifespan

Human Brain Mapping, Volume 47, Issue 4, March 2026.
An analysis of magnetoencephalography (MEG) recordings from 576 adults aged 18–87 years revealed frequency‐dependent changes in cortical functional connectivity across the adult lifespan, which are not explained by changes in source power. Beta‐band (13–30 Hz) connectivity at rest is associated with sensorimotor attenuation independent of these age ...

Atypical cortical neural activity in internet gaming disorder comorbid with autism spectrum disorder during a cue reactivity task: A magnetoencephalography study

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 1, March 2026.
Abstract Aim Significant, positive correlations between internet gaming disorder (IGD) and autism spectrum disorder (ASD) are known. Individuals with ASD are prone to problematic internet use due to addiction or restricted interests. Here, we examined cortical neural activity in individuals with IGD comorbid with ASD during a gaming‐related cue ...

Precision Measurement of the Newtonian Gravitational Constant Using Cold Atoms

, 2014
About 300 experiments have tried to determine the value of the Newtonian gravitational constant, G, so far, but large discrepancies in the results have made it impossible to know its value precisely.

Measurement of the Permanent Electric Dipole Moment of the $^{129}$Xe Atom

, 2019
We report on a new measurement of the CP-violating permanent Electric Dipole Moment (EDM) of the neutral $^{129}$Xe atom. Our experimental approach is based on the detection of the free precession of co-located nuclear spin-polarized $^3$He and $^{129 ...
