Advanced Science, EarlyView.Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Sporadic Dips from Extended Debris Transiting the Metal-rich White Dwarf SBSS 1232+563
The Astrophysical JournalWe present the discovery of deep but sporadic transits in the flux of SBSS 1232+563, a metal-rich white dwarf polluted by disrupted exoplanetary debris.

High-resolution Imaging Transit Photometry of Kepler-13AB [PDF]
The Astronomical Journal, 2019 Abstract Using the high-resolution imaging instrument, ’Alopeke, at the Gemini-N telescope, we obtained simultaneous two-channel time-series observations of the binary exoplanet host star Kepler13-AB. Our optical observations were obtained during a transit event of the exoplanet Kepler-13b and light curves were produced using both ...

Advanced Science, EarlyView.This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...

Precision photometry with difference imaging in the WTS
EPJ Web of Conferences, 2013 The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses aperture photometry to construct the light curves. We alternatively apply the

The Astronomical Journal, 2023 Previous studies of the exoplanet LTT 1445Ac concluded that the light curve from the Transiting Exoplanet Survey Satellite (TESS) was consistent with both grazing and nongrazing geometries. As a result, the radius and hence density of the planet remained

Advanced Science, EarlyView.Soil nutrient enrichment induces the trade‐offs between bacterial functional potential and growth‐rate potential. Such trade‐offs favor specific plant‐beneficial species and genes, playing a pivotal role in determining plant productivity. These findings enhance the understanding of the microbial responses in agroecosystems to ongoing global ...

Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e
The Astronomical JournalPlanets may be rotationally flattened, and their oblateness thus provides useful information on their formation and evolution. Here, we develop a new algorithm that can compute the transit light curve due to an oblate planet very efficiently and use it ...

The TESS-Keck Survey. XV. Precise Properties of 108 TESS Planets and Their Host Stars
The Astronomical Journal, 2023 We present the stellar and planetary properties for 85 TESS Objects of Interest (TOIs) hosting 108 planet candidates that compose the TESS-Keck Survey (TKS) sample.

Astronomische Nachrichten, EarlyView.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$
