High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Characterization and Computational Engineering of Structural Elements Controlling Gas Permeability in PIP2;1 Aquaporins

Journal of Computational Chemistry, Volume 47, Issue 11, 30 April 2026.
Bulky residues constrict the central pore of WT SoPIP2;1, generating high energy barriers for both O2 and CO2 and preventing gas permeation. ABSTRACT Aquaporins (AQPs) are classical water channels that also conduct small gas molecules such as O2$$ {\mathrm{O}}_2 $$ and CO2$$ {\mathrm{CO}}_2 $$ across the membrane.

Source reconstruction without an MRI using optically pumped magnetometer based magnetoencephalography [PDF]

Source modelling in magnetoencephalography (MEG) infers the spatial origins of electrophysiological signals in the brain. Typically, this requires an anatomical MRI scan of the subject’s head, from which models of the magnetic fields generated by the ...

Using Wearable MEG to Study the Neural Control of Human Stepping [PDF]

A central challenge in movement neuroscience is developing methods for non-invasive spatiotemporal imaging of brain activity during natural, whole-body movement. We test the utility of a new brain imaging modality, optically pumped magnetoencephalography

Unleashing the potential of OPM-MEG to study event-related fields against low-frequency artifacts: the case of sentence processing

bioRxiv
OPM-MEG (optically pumped magnetometers-magnetoencephalography) offers unprecedented opportunity in its proximity to the brain and in mobility, outperforming other human MEG systems.

Active and passive magnetic shielding for use in OPM-MEG [PDF]

Magnetic shielding is an essential part of many sensitive experiments including magnetoencephalography (MEG) systems that measure tiny magnetic fields generated by the simultaneous firing of neurons in the brain. Recent advances in MEG have arisen due to

Poster Session: Using OPM-MEG to study the timecourse of human contrast discrimination

Journal of Vision
The International Brain Laboratory (IBL) is a large-scale project collecting multiunit measurements from the mouse brain during a simple 2AFC perceptual decision task. The goal is to characterise the flow of information across the brain from sensory input areas through to motor outputs, and the way that this information flow can be modulated by priors.

Gradient phase and amplitude errors in atomic magnetic gradiometers for biomagnetic imaging systems

iScience
Summary: The cross-axis projection error (CAPE) caused by residual magnetic fields has recently attracted widespread attention. In this study, we propose a more specific theoretical model and expand the CAPE in gradient measurements. We first report that
