Advanced Science, EarlyView.Acinetobacter regulates dinotefuran tolerance in Propylea japonica by mediating the expression of the horizontally transferred gene PjDUF1. Abstract Insect–microbial symbiont relationships are widespread in nature and often involve lateral gene transfer.

Spectroscopy of Brown Dwarf Candidates in the rho Ophiuchi Molecular Core
, 1998 We present an analysis of low resolution infrared spectra for 20 brown dwarf candidates in the core of the $\rho$ Ophiuchi molecular cloud. Fifteen of the sources display absorption-line spectra characteristic of late-type stars.

EPJ Web of Conferences, 2011 From radial velocity (RV) detections alone one does not get all orbital parameters needed to derive the true mass of a non-transiting, unresolved substellar companion to a star.

The one that got away: a unique eclipse in the young brown dwarf Roque 12
The Open Journal of Astrophysics, 2020 We report the discovery of a deep, singular eclipse of the bona fide brown dwarf Roque 12, a substellar member of the Pleiades. The eclipse was 0.6mag deep, lasted 1.3h, and was observed with two telescopes simultaneously in October 2002.

The Astrophysical Journal Letters, 2023 We use recent microlensing observations toward the central bulge of the Galaxy to probe the overall stellar plus brown dwarf initial mass function (IMF) in these regions well within the brown dwarf domain. We find that the IMF is consistent with the same

An Eccentric Brown Dwarf Eclipsing an M dwarf
The Astronomical Journal, 2022 Abstract We report the discovery of an M = 67 ± 2M J brown dwarf transiting the early M dwarf TOI-2119 on an eccentric orbit (e = 0.3362 ± 0.0005) at an orbital period of 7.200861 ± 0.000005 days. We confirm the brown dwarf nature of the transiting companion using a combination of ground-based and space-based photometry

The Anatomical Record, EarlyView.Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Evidence for accretion in a nearby, young brown dwarf
, 2009 We report on the discovery of the young, nearby, brown dwarf 2MASS J0041353$-$562112. The object has a spectral type of M7.5, it shows Li absorption and signatures of accretion, which implies that it still has a disk and suggests an age below 10 Myr. The

SOLES XII. The Aligned Orbit of TOI-2533 b, a Transiting Brown Dwarf Orbiting an F8-type Star
The Astronomical JournalBrown dwarfs occupy a middle ground in mass space between gaseous giant planets and ultracool dwarf stars, and the characterisation of their orbital orientations may shed light on how these neighbouring objects form.
