A NEW BEE OF THE GENUS BOMBOMELECTA
The Canadian Entomologist, 1902 Bombomelecta Arizonica, n. sp.– ♀. Length about 11 mm., black; head, thorax and legs with dull white hair, having a faint yellowish tinge; black hair on cheeks, lower sides of face, labrum and mandibles; hair of pleura, except its upper part, black; a conspicuous band of black hair between the wings; hair of anterior legs long and black, but the ...

Advanced Materials, EarlyView.ABSTRACT Microneedle arrays (MNAs) is a rapidly emerging technology with broad biomedical applications in drug delivery and biosensing. With sub‐millimeter dimensions and periodicity, MNAs possess geometries nearly ideal for biomedical devices operating within the terahertz (THz) spectral window.

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Advanced Materials, EarlyView.Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...

Advanced Materials, EarlyView.Clinically, intermittent hypoxia (IH) is often accompanied by periodontitis, which accelerates cognitive impairment induced by IH. Novel Janus mesoporous gold‐silica nanoformulations (RVG‐Au&mSiO2‐TPP‐VB) enable intranasal delivery, achieve hierarchical targeting to neuronal mitochondria, effectively scavenge reactive oxygen species, inhibit the HIF‐1α/

NEW BEES OF THE GENUS COLLETES
The Canadian Entomologist, 1906 Colletes clypeonitens, n. sp.—. Length 11 mm. Clypeus prominent, polished, narrowly medially sulcate, its puncutres coarse but scattered and not forming striæ, its apex slightly emarginate and preceded by a transverse rim. Malar space one and one-half times as long as broad, finally striate.

Advanced Materials, EarlyView.Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...
