Researchers who combine machine learning and economics are studying the social impact of algorithms that determine payouts on digital marketplaces. In a recently published study, the team highlights the structural imbalance in digital labor markets and provides a blueprint for fairer market with better working conditions for gig workers.

Hybrid nanomaterials (HNMs) have become more interesting to researchers for various optoelectronic and biological applications. In response, this investigation focuses on the impact of loading ratios of (0, 1 %, 3 %, and 5 %) of HNMs from graphene oxide (GO) and silicon nitride (Si₃N₄). HNMs are utilized to reinforce blended polymers, including polyethylene oxide (PEO), carboxymethyl cellulose (CMC), and nano-polyaniline (PANI) to fabricate (PEO_100K–CMC–PANI/GO–Si₃N₄) using the developed sol–gel-ultrasonic procedure. X-ray diffraction revealed semi-crystalline behavior among all samples, while Fourier transform infrared spectroscopy showed strong physical interfacial interactions among the sample components. Meanwhile, field emission scanning electron and transmission electron microscopies showed a fine dispersion and a homogeneous matrix with significant changes. The optical absorption behavior revealed continuous high absorption peaks at 200–280-nm wavelengths, which strongly impacts (GO–Si₃N₄). Increases in concentration also strongly impact (GO–Si₃N₄), which results in an improved optical energy gap for the allowed and forbidden transitions from 3.5 eV for the blended polymer to 3 and 2.9 eV by increasing the HNM content. The contributions of HNMs notably enhance the ability to reduce the zones of the bacteria, especially Escherichia coli, from 18 to 26 mm. In effect, HNMs with a concentration higher than 5 % assist in inhibiting the growth of lung cancer (A549) cells. As such, these NCs present good optical behavior for multi-applications, such as biosensors and biological and optoelectronic devices.

Assisted reproductive technology (ART) has transformed infertility treatment but is associated with a 2–5-fold increased risk of ectopic pregnancy (EP) compared with natural conception. Despite accumulating evidence, a comprehensive bibliometric evaluation of ART-related EP (ART-EP) research—encompassing its evolution, knowledge gaps, and collaboration patterns—remains lacking. This study aimed to systematically map the ART-EP research landscape, identify critical gaps, and characterize global collaborative networks in alignment with the evidence-based optimization goals of the European Society of Human Reproduction and Embryology.
