Interaction between bacterial phytochromes Agp1 and Agp2 of Agrobacterium fabrum by fluorescence resonance energy transfer and docking studies

FEBS Letters, Volume 599, Issue 6, Page 848-865, March 2025.
The interaction between Agrobacterium fabrum phytochromes Agp1 and Agp2 was studied using FRET. Full‐length and truncated proteins with varied label positions provided spatial insights, narrowing down from many docking models to three. These models explain Agp2's reduction in Agp1 autophosphorylation, with Arg83 of Agp2 specifically evolved to interact

Twenty-One New Light Curves of OGLE-TR-56b: New System Parameters and Limits on Timing Variations [PDF]

, 2011
Although OGLE-TR-56b was the second transiting exoplanet discovered, only one light curve, observed in 2006, has been published besides the discovery data.

The Histone Lysine Demethylase KDM7A Contributes to Reward Memory via Fscn1‐Induced Synaptic Plasticity in the Medial Prefrontal Cortex

Advanced Science, Volume 12, Issue 10, March 13, 2025.
This research delineates the role of lysine demethylase 7A (KDM7A) in morphine‐induced reward memory and its effects on gene expression in the medial prefrontal cortex (mPFC). The study identifies fascin actin‐bundling protein 1 (Fscn1) as a downstream target of KDM7A, affecting dendritic spine density and neuronal activity, revealing novel insights ...

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

The 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

A new search for planet transits in NGC 6791

, 2007
Context. Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims. Considering the strong dependence of planet frequency on stellar metallicity, we studied the metal rich old

LHS 475 b: A Potential Venus Analog Orbiting a Nearby M Dwarf

The Astronomical Journal
Based on photometric observations by TESS, we present the discovery of a potential Venus analog transiting LHS 475, an M3 dwarf located 12.5 pc from the Sun. The mass of the star is 0.274 ± 0.015 M _☉ .

DECPHOT: an optimal deconvolution-based photometric reduction method [PDF]

arXiv, 2007
A high accuracy photometric reduction method is needed to take full advantage of the potential of the transit method for the detection and characterization of exoplanets, especially in deep crowded fields. In this context, we present DECPHOT, a new deconvolution-based photometry algorithm able to deal with a very high level of crowding and large ...

Millimagnitude Photometry for Transiting Extrasolar Planetary Candidates IV: The Puzzle of the Extremely Red OGLE-TR-82 Primary Solved

, 2007
We present precise new V, I, and K-band photometry for the planetary transit candidate star OGLE-TR-82. Good seeing V-band images acquired with VIMOS instrument at ESO VLT allowed us to measure V=20.6+-0.03 mag star in spite of the presence of a brighter

GJ 238 b: A 0.57 Earth Radius Planet Orbiting an M2.5 Dwarf Star at 15.2 pc

The Astronomical Journal
We report the discovery of the transiting planet GJ 238 b, with a radius of 0.566 ± 0.014 R _⊕ (1.064 ± 0.026 times the radius of Mars) and an orbital period of 1.74 days. The transit signal was detected by the TESS mission and designated TOI-486.01. The
