Begonia quadricornualata sp. nov. (Begoniaceae) from India

Nordic Journal of Botany, EarlyView.
A new species of Begonia L. (Begoniaceae) belonging to sect. Platycentrum is described from the Papum Pare District of Arunachal Pradesh, India. This new species is distinguished by its dense, long, red to brown hispid hairs on the adaxial leaf surface of female plants, caducous stipules and bracts, and solitary‐flowered female inflorescence ...

A Droplet‐Microarray Platform for Multiplex Profiling of Breast Cancer Exosome Subtypes in Patients’ Blood Plasma Samples

Small, EarlyView.
This study presents a droplet‐microarray platform integrated with a DNase I‐assisted MoS2 FRET aptasensor for multiplexed profiling of breast cancer subtypes’ exosomes from patients’ plasma. By targeting HER2, MUC1, and CD44, the system enables sensitive detection and accurate discrimination of luminal A, HER2‐positive, and triple‐negative subtypes ...

Rising from the Ashes: A Metallicity-dependent Star Formation Gap Splits the Milky Way’s α Sequences

The Astrophysical Journal
The elemental abundance distribution of stars encodes the history of the gas-phase abundance in the Milky Way. Without a large, unbiased sample of highly precise stellar ages, the exact timing and nature of this history must be inferred from the ...

Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

Small, EarlyView.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

The Milky Way Is a Less Massive Galaxy—New Estimates of the Milky Way’s Local and Global Stellar Masses

The Astrophysical Journal Letters
Stellar mass is the most fundamental property of a galaxy. While it has been robustly measured for millions of external galaxies, it remains poorly constrained for the Milky Way because of the strong selection effect from our inside perspective.

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the
