The bad timeline started when Olivia Nuzzi volunteered for Anthony Weiner's campaign for mayor of New York City in 2013.
Weiner resigned from the House in June 2011 after it was revealed that he had sent sexually suggestive photos of himself to various women. A second sexting scandal engulfed his 2013 campaign for New York City mayor. In September 2016, claims were published that Weiner had engaged in sexting with a 15-year-old girl from North Carolina; devices owned by Weiner were seized as part of an investigation into this incident. Information pertinent to the Hillary Clinton email controversy was discovered on Weiner's laptop, leading FBI Director James Comey to reopen his investigation into Clinton days before Clinton lost the 2016 presidential election to Donald Trump. Weiner later pleaded guilty to transferring obscene material to a minor and served more than a year in federal prison. https://en.wikipedia.org/wiki/Anthony_Weiner

"Odd moments arising from Uranus's observed north-south asymmetric flow are strong functions of the wind depth"

Looks like great work, but I have no self-control

arxiv.org/abs/2511.08698
Isolating the gravitational influence of Uranus's winds requires close passages inward of the rings Christopher R. Mankovich, Marzia Parisi, Damon F. Landau, Janosz W. Dewberry Close orbits by a Uranus Orbiter and Probe (UOP) could be used to deduce Uranus's multipolar gravity field to higher precision and angular degree than the J2 and J4 currently measured from ground-based ring occultations and the Voyager 2 flyby. We examine Jn sensitivity limits obtained from simulations of candidate UOP trajectories, pairing these with Uranus interior and wind models to perform retrievals from the gravity moments. We consider zonal wind profiles derived from recent feature-tracking data, assuming that zonal winds extend into the planet along cylinders, with a radial decay function similar to those that explain Jupiter and Saturn gravity. Present knowledge of J2 and J4 permits a fairly wide range of possible wind depths in Uranus, up to 1,800 km or 7% by radius. Measuring additional gravity moments is essential to separate this unknown wind depth from other interior properties of interest, but J6 is found to be too dominated by bulk rotation to be a useful probe of the wind depth. Odd moments arising from Uranus's observed north-south asymmetric flow are strong functions of the wind depth, but the usefulness of J3 is hindered by its sensitivity to present uncertainties in the wind profile. The even moment J8, or the odd moments J5 and J7, are the best probes of the depth of Uranus's winds. J8, and most likely J5 and J7, are measurable in a highly inclined orbit making >~10 pericenter passages inward of the ζ ring, approximately 1,000-2,500 km above Uranus's cloud tops. 17 pages, 9 figures, 2 tables.

Many people are asking
Is it possible to clear up the real history of the solar system? Vsekhsviatskii, S. K. Abstract The author holds that the eruptive theory of origin of cometary and meteoritic matter which he has defended for three decades is fully substantiated by lunar, Mars, and Venus data in recent space probings, and that condensation theories of cosmogony are without foundation. Mass, density, radius, mass loss, and rotational energy of the sun and all the planets are compared, as well as total mass of cometary material lost to the solar system and entering interstellar space. Meteoritic, asteroidal, and cometary matter is identified with volcanic ash and volcanic ejecta, plus frozen atmosphere components, including hydrates and clathrates. Protoplanets began their careers as masses of heated stellar material that subsequently cooled down, and the statistical theory of comets is the key to unraveling the origins of the solar system.

Pleiades: A lot more than seven sisters!

arxiv.org/abs/2511.07533
Lost Sisters Found: TESS and Gaia Reveal a Dissolving Pleiades Complex Andrew W. Boyle, Luke G. Bouma, Andrew W. Mann Most star clusters dissolve into the Galaxy over tens to hundreds of millions of years after they form. While recent Gaia studies have honed our view of cluster dispersal, the exact chronology of which star formation events begat which star cluster remnants remains unclear. This problem is acute after 100 Myr, when cluster remnants have spread over hundreds of parsecs and most age estimates for main sequence stars are too imprecise to link the stars to their birth events. Here we develop a Bayesian framework that combines TESS stellar rotation rates with Gaia kinematics to identify diffuse remnants of open clusters. We apply our method to the Pleiades, which previous studies have noted shows kinematic similarities to other nearby young stellar groups. We find that the Pleiades constitutes the bound core of a much larger, coeval structure that contains multiple known clusters distributed over 600 pc. We refer to this structure as the Greater Pleiades Complex. On the basis of uniform ages, coherent space velocities, detailed elemental abundances, and traceback histories, we conclude that most stars in this complex originated from the same giant molecular cloud. This work establishes a scalable approach for tracing the genealogies of nearby clusters and further cements the Pleiades as a cornerstone of stellar astrophysics. We aim to apply this methodology to other associations as part of the upcoming TESS All-Sky Rotation Survey. Comments: Published in The Astrophysical Journal. Figure 15 is my favorite!
