Active Young Stars in the LAMOST–Kepler Survey
The Astrophysical Journal Supplement SeriesIn the early stages of their lives, young stars harbor diverse processes exhibiting strong signatures, making them ideal targets for investigating stellar accretion, dynamo actions, and exoplanet formation.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Gaia21bja: Pre-main-sequence Star with Quasiperiodic Bursts
The Astrophysical JournalGaia21bja is a Gaia alerted young stellar object (YSO) that exhibits at least seven quasiperiodic brightenings over a 20 yr long light curve with durations of 1.5–2 yr and amplitudes up to ∼1.7 mag in the Gaia G band.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Discovery of the pre-main-sequence eclipsing binary MML 48 [PDF]
Aims. We present the discovery of the eclipsing binary MML 48, which is a member of Upper Centaurus Lupus, has an associated age of 16 Myr, and is composed of two young, low-mass stars.Methods. We used space- and ground-based observations to characterize

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Polarization: A Method to Reveal the True Nature of the Dusty S-Cluster Object (DSO/G2)
Galaxies, 2018 There have been different scenarios describing the nature of a dusty source, noted as Dusty S-cluster Object (DSO) or G2, orbiting around the Galactic centre super-massive black hole.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
