Transiting Planetary Debris near the Roche Limit of a White Dwarf on a 4.97 hr Orbit—and its Vanishing

The Astrophysical Journal
We present the discovery of deep, irregular, periodic transits toward the white dwarf ZTF J1944+4557 using follow-up time-series photometry and spectroscopy from Palomar, Keck, McDonald, Perkins, and Lowell observatories.

TESS Timings of 31 Hot Jupiters with Ephemeris Uncertainties

The Astrophysical Journal Supplement Series, 2023
A precise transit ephemeris serves as the premise for follow-up exoplanet observations. We compare TESS Object of Interest (TOI) transit timings of 262 hot Jupiters with the archival ephemeris and find 31 of them having TOI timing offsets, among which ...

Cracking the Valence Code: Patterned Facial Kinematics and Neural Signatures of Emotional Expressions in Mice

Advanced Science, EarlyView.
An AI‐powered system decodes emotional valence from mouse facial expressions, identifying ear dynamics as key indicators. By integrating facial kinematics with synchronized neural recordings, this approach establishes a direct link between behavior and brain activity, advancing automated emotion recognition in animal models.

Time‐Dependent Therapeutic Effect of S‐Ketamine on PTSD Mediated by VTA‐OFC Dopaminergic Neurocircuit

Advanced Science, EarlyView.
This study reveals that early rather than late administration of S‐ketamine can ameliorate PTSD symptoms. This phenomenon is attributed to reversing the progressive inhibition of VTADA neurons and the function of VTADA‐OFC circuit following stress. Targeted stimulation of the OFC by TI‐NIBS to enhance DA release effectively extends the therapeutic time

Updated Masses for the Gas Giants in the Eight-planet Kepler-90 System Via Transit-timing Variation and Radial Velocity Observations

The Astronomical Journal
The eight-planet Kepler-90 system exhibits the greatest multiplicity of planets found to date. All eight planets are transiting and were discovered in photometry from the NASA Kepler primary mission. The two outermost planets, g ( P _g  = 211 days) and h

The stellar variability noise floor for transiting exoplanet photometry with PLATO [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT One of the main science motivations for the ESA PLAnetary Transit and Oscillations (PLATO) mission is to measure exoplanet transit radii with 3 per cent precision. In addition to flares and starspots, stellar oscillations and granulation will enforce fundamental noise floors for transiting exoplanet radius measurements.

Cortico‐Striatal‐Midbrain Circuit Dysregulation Underlying MK‐801 Induced Impulsivity and the Ameliorative Effects of SEP

Advanced Science, EarlyView.
Impulsivity is a symptom across multiple psychiatric disorders, yet its neural basis remains elusive. This study shows that the NMDAR antagonist MK‐801 elevates dopamine release and disrupts neuronal selectivity in the nucleus accumbens, leading to impulsive behavior.
