Modified comet assays for the detection of cyclobutane pyrimidine dimers and oxidative base damages
Journal of Radiation and Cancer Research, 2017 The comet assay (also known as single-cell gel electrophoresis) is a technique for the detection of DNA damage at the level of the individual cell. It is a versatile, relatively simple to perform and sensitive method.

Detection of comet nuclei at large heliocentric distances [PDF]
Monthly Notices of the Royal Astronomical Society, 1992 The largest long-period comets which have passed perihelion during the past half-century should still be observable. Fourteen candidate comets with well-determined orbits are presented, including data on their absolute magnitudes, distances and predicted positions in the sky.

A Sub‐Microsecond Switch Enabling SWIFT 23Na Imaging at 10.5 T
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To enable sodium SWIFT imaging, which is a zero‐echo time imaging technique, at ultra‐high magnetic fields through the development of custom electronics hardware, and to showcase this capability with in vivo imaging results. Methods The custom hardware developed consists of a high‐speed optical trigger with 10 ns resolution, an in‐bore

Journal of Field Robotics, EarlyView.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail
Small, EarlyView.The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.

Multiple Outbursts of Halley-type Comet 12P/Pons–Brooks
The Astronomical JournalWe present optical observations of the Halley-type comet 12P/Pons–Brooks (12P) on its approach to perihelion. The comet was active even in the first observations at ∼8 au.
