  • MicroRNA maturation is initiated by the Microprocessor that cleaves primary microRNA hairpins. Here, the authors uncover distinct roles of two auxiliary factors of the Microprocessor, ERH and SAFB2, in the processing of suboptimal clustered microRNA hairpins.

  • Farside solar magnetograms are generated from STEREO images using deep learning, with Hale-patterned active regions being well reproduced. These images can be used to monitor the temporal evolution of magnetic fields from the farside to the frontside.

  • Superconducting (SC) gap of elemental yttrium under extreme pressure conditions was directly probed via the point-contact spectroscopy (PCS) in a diamond anvil cell. Strong enhancement in the differential conductance near the zero-biased voltage is observed owing to Andreev reflection, a hallmark of superconductivity. Taken together with the large initial slope of the upper critical field, the large SC gap-to-Tc ratio suggests that Y belongs to a family of the strongly coupled BCS superconductors.

  • Heavy-fermion superconductors feature a magnetic quantum critical point linked to the Kondo effect breakdown. Wang et al. use pressure-dependent Hall measurements to identify a crossover energy scale, confirming this in pure CeRhIn5, while revealing a shift to spin density wave criticality with Sn-doping.

  • Large inhomogeneous electronic states in rare-earth-doped CaFe2As2 produce striking results of manipulating the superconducting phases via current-driven magnetic state. Magnetization hysteresis loops at superconducting state (2 K) and normal state (50 K) for La-doped CaFe2As2 are largely changed by the electric current because their high-Tc regions are localized. Current path between high-Tc regions is considered as a long wire, thus current-induced large magnetic field around the path can modulate the magnetic state in normal/weak superconducting regions. These observations provide new insights into the role of Fe in the Fe-based superconductors and ideas for the design of new superconducting devices.
