Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

A Brain‐Wide Atlas of Astrocytic Oxytocin Receptors Reveals a Glial Basis for Nucleus Accumbens Modulation of Affiliative Behavior

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
The cellular actors of oxytocin signaling are under intense scrutiny. A brain‐wide anatomical and functional analysis in mice and rats reveals widespread expression of oxytocin receptors in astrocytes. These receptors are functionally active and, in the nucleus accumbens, selectively regulate male social affiliation.

A 0.7 to 30 GHz Coplanar Vivaldi Antenna

open access: yesMicrowave and Optical Technology Letters, Volume 68, Issue 8, August 2026.
ABSTRACT In the literature there are multiple Vivaldi antenna designs that have a wide impedance bandwidth; however, the usable bandwidth is often limited by pattern degradation at the higher frequencies of the band. This paper presents the design and implementation of a coplanar Vivaldi antenna with a 42.9:1 usable bandwidth ratio (0.7–30 GHz).

Time‐resolved PET imaging using a joint dynamic reconstruction and motion estimation framework (DREME‐PET)

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Positron emission tomography (PET) plays a critical role in image‐guided radiotherapy by enabling accurate tumor localization and contouring. To account for respiration‐induced anatomical motion, time‐resolved PET imaging is highly desirable, as it captures dynamic anatomical variations to facilitate both disease diagnosis and ...

Being wronged and being right: Meaningful Indigenous‐Māori discourses for enhancing environmental restoration

open access: yesPeople and Nature, Volume 8, Issue 8, Page 2781-2795, August 2026.
Abstract Indigenous participation in environmental management is essential for achieving just and effective ecological outcomes. This study investigates the positive discourses that support the integration of Te Ao Māori (the Māori world view) in environmental restoration practice in Aotearoa New Zealand. We introduce Kaupapa Māori Discourse Analysis—a
