The Comet Assay for the Evaluation of Genotoxic Potential of Landfill Leachate

The Scientific World Journal, 2012
Genotoxic assessment of landfill leachate before and after biological treatment was conducted with two human cell lines (Me45 and NHDF) and Daphnia magna somatic cells. The alkali version of comet assay was used to examine genotoxicity of leachate by DNA

CDK4/6 Inhibitors and Curcumin Synergistically Suppress HER2− Breast Cancer via Lethal ROS and Inhibition of Metastasis

Cancer Science, EarlyView.
Schematic illustrating that CDK4/6 inhibitors combined with curcumin induce lethal ROS accumulation by disrupting redox balance, downregulating GPX4, and depleting glutathione, leading to DNA damage and lipid peroxidation. This oxidative stress triggers tumor cell death and suppresses EMT‐driven migration.

Observations of counter-streaming ions in and around the diamagnetic cavity of comet 67P

Astronomy & Astrophysics
Context. Ion speeds at comet 67P/Churyumov-Gerasimenko significantly exceed local neutral gas speeds, a discrepancy that challenges current ion-neutral coupling models.

Two dimensional hybrid simulations of small scale obstacles in the solar wind [PDF]

The structure and dynamics of the solar wind interaction with two small scale obstacles (of the order of a pickup ion gyroradius) is examined. These are a comet, comparable to Grigg-Skjellerup, and a weakly ionospheric planet.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Search for the True Parent Body of the Phoenicid Meteor Shower

The Astronomical Journal
In 2024, Ďurišová et al. found that the meteor shower Phoenicids, IAU No. 254, code PHO, can originate in the nuclei of three comets, 46P/Wirtanen, 104P/Kowal 2, and 289P/Blanpain.

TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps

Computer Graphics Forum, EarlyView.
Abstract We present TreeON, a novel neural‐based framework for reconstructing detailed 3D tree point clouds from sparse top‐down geodata, using only a single orthophoto and its corresponding Digital Surface Model (DSM). Our method introduces a new training supervision strategy that combines both geometric supervision and a differentiable shadow and ...

Small glitches, but Rosetta comet mission is achieving major scientific goals [PDF]

, 2014
First paragraph: The landing of Rosetta’s Philae on comet 67P/Churyumov–Gerasimenko was a triumph of engineering. Many spectacular scientific firsts will follow now, but small glitches during the landing make it more difficult to obtain all ...
