Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

Environmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Nongravitational Forces in Planetary Systems

The Planetary Science Journal
Nongravitational forces play surprising and, sometimes, centrally important roles in shaping the motions and properties of small planetary bodies. In the solar system, the morphologies of comets, the delivery of meteorites, and the shapes and dynamics of

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

How weather got its words: a history of meteorological English – Part 2: the scientific age and beyond

Weather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.

A study of the orbital evolution of 10 short-period comets by solving differential equations of motion obtained on the basis of a new principle of interaction

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
The research of the orbital evolution of 10 short-period comets on the time interval of 400 years (1800–2200) is made by solving the differential equations of motion based on the new principle of mutual interaction of material bodies.

Fleeting Feminism: The Singapore Women's Federation, Singapore Chinese Left‐Wing Feminism and Anti‐Colonial Nationalism, c. 1950s

Gender &History, EarlyView.
ABSTRACT In 1955, two female factory workers and trade union leaders, Tan Lee Eng and Kwek Tai Eng, established the Singapore Women's Federation (SWF) to unite women regardless of race, religion or class for the anti‐colonial nationalist struggle. Singapore Chinese left‐wing feminism emerged at the confluence of the nationalist interest in mobilising ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?

Global Policy, EarlyView.
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

JWST and Gemini Observations of the Active Centaur 450P/LONEOS: Nucleus and Coma Characterizations

The Planetary Science Journal
Between 2019 and 2024, we used the Gemini-N and JWST observatories to conduct a detailed case study of the active Centaur 450P/LONEOS, whose orbit was significantly altered by a close Saturn encounter in 1992.

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review

Addiction, EarlyView.
Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

Deep learning-enabled size estimation of comets indicates a more dynamic early solar system

Nature Communications
The formation and evolution of the Solar System’s two major comet reservoirs, the Oort Cloud and the Scattered Disk, remain poorly constrained. Observations of comet flux imply a population ratio between these reservoirs that exceeds predictions from ...
