Evaluation of growth and yield of new papaya (Carica papaya L.) hybrid lines and their performance against Moroccan watermelon mosaic virus‐causing disease

Biological Diversity, EarlyView.
Abstract The production of Carica papaya L. in Kenya is seriously affected by the Moroccan watermelon mosaic virus and lack of improved varieties leading to the importation of expensive seeds for the resource‐scarce farmers. To curb these challenges, new papaya hybrid lines were recently selected and bred, but their growth traits and performance ...

Unrecognised ant megadiversity in the Australian monsoonal tropics: The Melophorus dicyrtos Heterick, Castalanelli and Shattuck complex

Biological Diversity, EarlyView.
Here we show that the ant Melophorus dicyrtos from Australia's monsoonal (seasonal) tropics represents dozens of species. It is further documentation of undescribed ant hyperdiversity in the region, which appears to harbour the world's richest ant fauna.

An Informed and Systematic Method to Identify Variable Mid-L Dwarfs

The Astrophysical Journal
Most brown dwarfs show some level of photometric or spectral variability. However, finding the most variable dwarfs more suited for a thorough variability monitoring campaign remained a challenge until a few years ago with the design of spectral indices ...

Hydroxyl radical enhanced carbon dots fluorescence quenching immunoassays for simultaneous detection of six kinds of antibiotics

Food Bioengineering, Volume 1, Issue 3-4, Page 212-223, December 2022., 2022
A label‐free fluorescence quenching immunoassays using hydroxyl radical‐sensitive carbon dots as fluorescence probe was established for simultaneous extraction and highly sensitive detection of six wide‐spectrum antibiotics (nitrofuran metabolites, chloramphenicol, and florfenicol) in animal‐derived food.

HCN and C2H2 in the Atmosphere of a T8.5+T9 Brown Dwarf Binary

The Astrophysical Journal Letters
T-type brown dwarfs present an opportunity to explore atmospheres teeming with molecules such as H _2 O, CH _4 , and NH _3 , which exhibit a wealth of absorption features in the mid-infrared.

JWST 1.5 μm and 4.8 μm Photometry of Y Dwarfs

The Astronomical Journal
Brown dwarfs lack nuclear fusion and cool with time; the coldest known have an effective temperature below 500 K, and are known as Y dwarfs. We present a James Webb Space Telescope (JWST) photometric data set of Y dwarfs: 23 were imaged in wide-field ...
