Article Synopsis
  • Iron is important for health, and it seems to be linked to a condition called polycystic ovary syndrome (PCOS) that affects some women.
  • Researchers looked at various studies to see if a substance called hepcidin, which helps control iron, is different in women with PCOS compared to those who are healthy.
  • They found that women with PCOS generally had lower levels of hepcidin, which might help doctors understand and diagnose PCOS better in the future.

Soft grippers due to their highly compliant material and self-adaptive structures attract more attention to safe and versatile grasping tasks compared to traditional rigid grippers. However, those flexible characteristics limit the strength and the manipulation capacity of soft grippers. In this paper, we introduce a hybrid-driven gripper design utilizing origami finger structures, to offer adjustable finger stiffness and variable grasping range.

Article Synopsis
  • Bacteria prevalent in various environments are an important source of natural products, particularly nonribosomal lipopeptides, which have significant biological activities.
  • These lipopeptides are critical in the development of antibiotics, with daptomycin being a notable example used in clinical settings.
  • Recent advancements in chemistry and biology have enhanced our understanding of the biosynthesis and functions of lipopeptides, including novel discovery methods like genome mining, indicating their potential for future medical applications.

A complete understanding of the interaction between electromagnetic radiation and semiconductor nanowires (NWs) is required in order to further develop a new generation of opto-electronic and photonic devices based on these nanosystems. The reduced dimensionality and high aspect ratio of nanofilaments can induce strong polarization dependence of the light absorption, emission and scattering, leading in some cases to the observation of optical antenna effects. In this work we present the first systematic study of polarized Rayleigh back-scattering from individual crystalline semiconductor NWs with known crystalline structure, orientation and diameters.

We report on investigations of the interaction of light with nanoscale antennae made from crystalline GaP nanowires (NWs). Using Raman scattering, we have observed strong optical antenna effects which we identify with internal standing wave photon modes of the wire. The antenna effects were probed in individual NWs whose diameters are in the range 40 < d < 300 nm.
