Intermediate report on the Delphi study: Findings from the 2nd and the 3rd STELLAR Delphi rounds: Areas of tension and core research areas

, 2011
This intermediate report on the STELLAR Delphi study closes the gap between the first deliverable on the Delphi study D1.3 (Spada et al. 2010) which was published in July 2010 and the second and final deliverable D1.6 which is planned for January 2012 ...

Searching for Stellar Activity Cycles Using Flares: The Short- and Long-timescale Activity Variations of TIC-272272592

The Astronomical Journal
We examine 4 yr of Kepler 30 minutes data, and five sectors of Transiting Exoplanet Survey Satellite 2 minutes data for the dM3 star KIC-8507979/TIC-272272592. This rapidly rotating ( P = 1.2 day) star has previously been identified as flare active, with

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Final report on the STELLAR Delphi study: Future directions for TEL and TEL research: areas of tension, core research areas and grand challenge problems

, 2012
In this report on the STELLAR Delphi study, we present the results of the final global survey, that is the 4th STELLAR Delphi round, and illustrate the elaboration and dissemination of these results (5th STELLAR Delphi round).

Properties of Flare Quasiperiodic Pulsations Based on a New TESS Flare Catalog

The Astrophysical Journal Supplement Series
Stellar flares are important indicators of stellar magnetic activity and have been widely studied. Detailed studies of flares have raised new questions. For example, the quasiperiodic pulsation (QPP) phenomenon in flares challenges standard flare models,

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Magnetic Activity in X-Ray Stars from eROSITA: Insights from the TESS and LAMOST Surveys

The Astrophysical Journal Supplement Series
We have focused on investigating X-ray stars obtained from eROSITA Data Release 1 (eRASS1) and conducting crossmatching with the TESS and LAMOST surveys.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
