Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Starspots: A Key to the Stellar Dynamo

Living Reviews in Solar Physics, 2005
Magnetic activity similar to that of the Sun is observed on a variety of cool stars with external convection envelopes. Stellar rotation coupled with convective motions generate strong magnetic fields in the stellar interior and produce a multitude of ...

Zeeman Doppler Imaging of τ Ceti: The Weakest Magnetic Field Detected in a Sun-like Star

The Astrophysical Journal Letters
For nearly a decade, observations have shown that many older Sun-like stars spin faster than predicted, a phenomenon known as weakened magnetic braking (WMB). The leading hypothesis for WMB is a weakening of the large-scale dipole field, which leads to a

The Effects of Rotation, Metallicity, and Magnetic Field on the Islands of Failed Supernovae

The Astrophysical Journal, 2023
Failed supernovae (FSN) are a possible channel for the formation of heavy stellar-mass black holes ( M _BH > ∼30 M _⊙ ). However, the effects of metallicity, rotation, and magnetic field on the islands of explodabilty of massive stars are not clear. Here,

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Stellar Cycle Variability in Mount Wilson Stars and Dynamo Models: Rotation Rate and Dynamo Number Dependency

The Astrophysical Journal
Similar to the solar cycle, the magnetic cycles of other solar-type stars are also variable. How the variability of the stellar cycle changes with the rotation rate or the dynamo number is valuable information for understanding the stellar dynamo process.

Rotational Components of the Sun’s Mean Field

The Astrophysical Journal, 2023
This paper uses wavelet transforms to look for the rotational frequencies of the Sun’s mean line-of-sight magnetic field. For a sufficiently high wavelet frequency, the spectra of the dipole, quadrupole, and hexapole field components each show a time ...

Stellar oscillations in the presence of a magnetic field [PDF]

Monthly Notices of the Royal Astronomical Society, 1986
We investigate the problem of stellar pulsation in the presence of a magnetic field, for arbitrary frequencies and horizontal wavenumbers. Magnetic effects are strong in a boundary layer close to the stellar surface, but it is possible to identify independent Alfvénic-type modes at sufficient stellar depth.

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

FEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.
