Moreover, none of them could reliably integrate novel information into their memories. Overall, our study casts doubt on the existence of WWW memory in great apes, and especially calls for more caution when using WWW memory tasks and interpreting their results.

Herein, we demonstrate that spin engineering of trimetallic Pd-Fe-Pt nanomeshes (NMs) can achieve superior enhancement for fuel electrooxidations. Magnetization characterizations reveal that Pd59Fe27Pt14 NMs own the highest number of polarized spins (μb = 0.85 μB/f.u.), playing an important role on facilitating the adsorption of OHads to promote the oxidation of COads, as confirmed by theoretical results. Consequently, the optimized Pd59Fe27Pt14 NMs exhibit excellent methanol oxidation reaction activity and stability with a mass activity of 1.61 A mgPt-1, 2.6-fold and 7.3-fold larger than those of PtRu/C and Pt/C. Such catalysts also present exceptional performances in ethanol oxidation and formic acid oxidation reactions. Our work highlights a new strategy for designing efficient electrocatalysts for fuel electrooxidations and beyond.Combinatorial biosynthesis of 5/5/6 type polycyclic tetramate macrolactams (PoTeMs) was achieved in an engineered ikarugamycin (5/6/5 type) producer by introducing a set of 5/5/6 type PoTeM biosynthetic genes from Streptomyces griseus. This study supports the idea that PoTeMs share a common polyene tetramate prec
