Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Coil Sketching for Fast and Efficient 4D Lung MRI Reconstruction

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2241-2253, April 2026.
ABSTRACT Purpose To develop and evaluate a memory‐efficient and accelerated reconstruction framework for respiratory‐resolved 4D lung MRI using coil sketching and Toeplitz approximation, enabling high‐quality motion‐compensated low‐rank (MoCo‐LR) reconstructions on clinically accessible GPU hardware.

Increasing the measurable frequency range of magnetic field oscillations with off‐resonance spin‐lock preparation pulses

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1634-1643, March 2026.
Abstract Purpose Oscillatory magnetic fields—arising from, e.g., neuronal currents or induced currents during brain stimulation—can be measured with spin‐lock preparation pulses, where the frequency of the measured field matches the amplitude of the spin‐lock pulse.

Novel Kanamycin/Neomycin Phosphotransferase Cassette Increases Transformation Efficiency in E. coli

BioTechniques, 2000
Stable transformation depends on the efficient delivery of DNA into cells and the robust expression of genes that encode proteins which provide resistance to selective (cytotoxic) compounds.

3D inversion recovery ultrashort echo time MRI can detect demyelination in cuprizone-treated mice

Frontiers in Neuroimaging
PurposeTo test the ability of inversion-recovery ultrashort echo time (IR-UTE) MRI to directly detect demyelination in mice using a standard cuprizone mouse model.MethodsNon-aqueous myelin protons have ultrashort T2s and are “invisible” with conventional

Plant accession and insect infestation, rather than silicon supplementation, shape defence strategies of Arabidopsis halleri towards a leaf beetle

Plant Biology, Volume 28, Issue 2, Page 407-419, March 2026.
Chemical and mechanical defences of a metal‐hyperaccumulating plant species Arabidopsis halleri were more influenced by plant accession (genetic background) and insect herbivory by a leaf beetle Phaedon cochleariae than by supplementation of the metalloid silicon.

Comparison of diagnostic performance for pulmonary nodule detection between free-breathing spiral ultrashort echo time and free-breathing radial volumetric interpolated breath-hold examination

BMC Medical Imaging
Objective This study aims to evaluate the efficacy of two free-breathing magnetic resonance imaging (MRI) sequences—spiral ultrashort echo time (spiral UTE) and radial volumetric interpolated breath-hold examination (radial VIBE).
