Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Manipulation of Ferroic Orders via Continuous Biaxial Strain Engineering in Multiferroic Bismuth Ferrite

open access: yesAdvanced Science, EarlyView.
This study explores the evolution of ferroelectric (FE) and antiferromagnetic (AFM) orders in freestanding BiFeO3 films under anisotropic strain using rotational anisotropy second harmonic generation (RA‐SHG) and first‐principles calculations. The research reveals reversible control of in‐plane FE polarization and significant AFM order rotation ...

Sonochemically‐Induced Reduction of Alkenes to Alkanes with Ammonia

open access: yesAngewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Ammonia is used as a hydrogen source for the reduction of alkenes to alkanes. The originality stems from the use of cavitation bubbles that act as “microreactors” to break the N−H bond of NH3. As a result, this protocol does not involve any catalyst and it releases nitrogen (and partly hydrogen) as a sole co‐product.

PRMT1‐Mediated SWI/SNF Complex Recruitment via SMARCC1 Drives IGF2BP2 Transcription to Enhance Carboplatin Resistance in Head and Neck Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
PRMT1 drives carboplatin resistance and tumor progression in head and neck squamous cell carcinoma (HNSCC) through a novel, methyltransferase‐independent mechanism. It recruits the SWI/SNF complex to activate IGF2BP2, promoting tumor growth and carboplatin resistance. PBX2 upregulates PRMT1, reinforcing this pathway. This study uncovers a non‐catalytic
