Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

PanGraphRNA: An efficient and flexible bioinformatics platform for graph pangenome‐based RNA‐seq data analysis

Journal of Integrative Plant Biology, EarlyView.
PanGraphRNA is an easy‐to‐use platform that improves RNA‐seq analysis by using graph pangenomes instead of a single reference genome. It increases read alignment accuracy, detects important genes missed by traditional methods, and works across major crops, helping researchers obtain more reliable transcriptome results for diverse plant research and ...

The Complex Multiwavelength Morphology of the Peculiar Compact Galaxy Group IC 2431

The Astrophysical Journal
We present new Chandra X-ray imaging spectroscopy of the compact galaxy group IC 2431, and compare with archival ultraviolet, optical, infrared, and radio images. IC 2431 is a starburst system containing three tidally distorted disk galaxies.

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Initial study of regolith exposure ages and burial conditions on Ryugu: Cosmogenic nuclides score in two touchdowns

Meteoritics &Planetary Science, EarlyView.
Abstract Surface processes on the asteroid Ryugu have been investigated using cosmic‐ray‐produced radionuclides, 10Be, 26Al, and 36Cl, and stable noble gases, on eight samples returned by the Hayabusa2 spacecraft. The 10Be and 26Al along with 21Ne measurements indicate that the two Chamber A samples A0105 collected during the first touchdown (TD) were ...

Dynamics of Galaxy Interactions [PDF]

, 1998
This review briefly and very informally summarizes some of my ongoing research. One unifying theme in my work is the use of computers to bridge the gap between human and astronomical time-scales. Galactic collisions are an example; the dynamics of interacting galaxies can be visualized with numerical simulations.

Model Calculations for Cosmogenic Nuclides in Meteorites and the Lunar Surface. 1. Long‐lived Radionuclides

Meteoritics &Planetary Science, EarlyView.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

H i, FRB, What’s Your z: The First FRB Host Galaxy Redshift from Radio Observations

The Astrophysical Journal Letters
Identification and follow-up observations of the host galaxies of fast radio bursts (FRBs) not only help us understand the environments in which the FRB progenitors reside, but also provide a unique way of probing the cosmological parameters using the ...
