Optical control of the hypothalamic arcuate nucleus kisspeptin neuronal network with a photoswitchable peptide that drives luteinizing hormone release in female mice

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Pulsatile gonadotropin‐releasing hormone (GnRH) and luteinizing hormone (LH) secretion are essential for reproductive function and are thought to be governed by arcuate nucleus kisspeptin Kiss1ARH neurons via neurokinin B (NKB) signaling through TacR3.

Bolide light curve systematics from 75 recovered meteorites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2351-2392, September 2026.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

Searching for GEMS: Discovery and Characterization of Two Brown Dwarfs Around M Dwarfs

open access: yesThe Astronomical Journal
Brown dwarfs bridge the gap between stars and planets, providing valuable insight into both planetary and stellar-formation mechanisms. Yet the census of transiting brown-dwarf companions, in particular around M-dwarf stars, remains incomplete. We report

Constraining exotrojans in hot-Jupiter systems using transit timing variation observations from TESS

open access: yesAstronomy & Astrophysics
Context. Co-orbital objects, also known as Trojans, are celestial bodies that share a 1:1 mean motion resonance orbit with a planet. Many planets in our Solar System hold Trojans, yet none has been confirmed in exoplanetary systems.

Transit and secondary eclipse photometry in the near-infrared

open access: yes, 2007
Near-infrared photometry of transiting extrasolar planets can be of great scientific value. It is however not straightforward to reach the necessary millimagnitude precision. Here we report on our attempts to observe transits and secondary eclipses of several extrasolar planets at 2.2 micron.

Impact of Salinity Duration on Growth, Photosynthesis, Water Relations, and Recovery Capacity Reveals Adaptive Responses in Hordeum maritimum

open access: yesPhysiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Although the physiological mechanisms underlying salt tolerance in wild barley (Hordeum maritimum) are relatively well understood, its recovery after salt stress remains poorly characterized. In this pot experiment, plants were exposed to 200 mM NaCl for 0, 15, 30, 45, or 60 days to evaluate changes in growth and water status.

Functional Effects of the Pioneer Fern Dicranopteris on Soil Fertility and Its Spatial Patterns in Degraded Hilly Landscapes

open access: yesLand Degradation &Development, Volume 37, Issue 14, Page 10340-10354, 30 August 2026.
ABSTRACT Vegetation recovery is vital for reversing soil degradation in subtropical red soil regions. This study evaluates the role of the pioneer fern Dicranopteris in enhancing soil fertility and its spatial variability across degraded hills in South China.
