Molecular Oncology, EarlyView.Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

The Astrophysical JournalStellar magnetic fields have a major impact on space weather around exoplanets orbiting low-mass stars. From an analysis of Zeeman-broadened Fe i lines measured in near-infrared SDSS/APOGEE spectra, mean magnetic fields are determined for a sample of 29 ...

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 ...

Observations of Cool-Star Magnetic Fields
Living Reviews in Solar Physics, 2012 Cool stars like the Sun harbor convection zones capable of producing substantial surface magnetic fields leading to stellar magnetic activity. The influence of stellar parameters like rotation, radius, and age on cool-star magnetism, and the importance ...

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,

Relationships Between Solar and Stellar Magnetic Fields [PDF]
Symposium - International Astronomical Union, 1983 Observational and theoretical studies of solar and stellar magnetic fields are reviewed. The discussion draws together several themes that emerged during IAU Symposium 102 on “Solar and Stellar Magnetic Fields: Origins and Coronal Effects,” and identifies a number of areas in which research over the next few years is likely to be fruitful.

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.
