Phase-resolved Hubble Space Telescope WFC3 Spectroscopy of the Weakly Irradiated Brown Dwarf GD 1400 and Energy Redistribution–Irradiation Trends in Six White Dwarf–Brown Dwarf Binaries

The Astrophysical Journal
Irradiated brown dwarfs offer a unique opportunity to bridge the gap between stellar and planetary atmospheres. We present high-quality Hubble Space Telescope/Wide Field Camera 3/G141 phase-resolved spectra of the white dwarf–brown dwarf binary GD 1400 ...

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

37 NEW T-TYPE BROWN DWARFS IN THE CANADA-FRANCE BROWN DWARFS SURVEY

The Astronomical Journal, 2011
The Canada-France Brown Dwarfs Survey is an i'- and z'-band survey realized with MegaCam at the Canada-France-Hawaii Telescope that covers a surface area of 780 deg2. Image analysis is now completed while J-band follow-up campaigns are ~90% done. The survey identified about 70 T dwarf candidates, of which 43 now have near-infrared spectra obtained with

Welcome to the Jungle: An Examination of the Making of Science Standards

Science Education, EarlyView.
ABSTRACT Nearly 50 million public school students in the United States are required to learn the content prescribed by state‐mandated science standards. Although much is known about the implementation of science standards and teachers' perceptions of them, the development process of these standards remains unclear.

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.

Perspectives on Climate Change in Education for Sustainability: Linking Concepts and Skills for a Practical Ecological Transition

Sustainable Development, EarlyView.
ABSTRACT ‘Hard’ natural sciences have extensively been used to provide evidence that climate change is happening and climate action is needed. If the contribution of our economic activities to disturbing our climate systems is now largely accepted, the way in which we design and operationalise ‘climate action’—how we transition to more sustainable ...

What Management Control Practices Do Electric Utilities Rely on When It Comes to Fostering the Social Pillar of Sustainability? A Comparative Analysis of the European Union and the United States

Sustainable Development, EarlyView.
ABSTRACT Electric utilities are expected to implement measures to improve their performance in all three dimensions of sustainable development—environmental, social, and economic. While several studies have investigated the environmental dimension, measures related to the social pillar have hardly been researched to date.

Medium-resolution 0.97–5.3 μm Spectra of Very Young Benchmark Brown Dwarfs with NIRSpec on Board the James Webb Space Telescope

The Astronomical Journal
Spectra of young benchmark brown dwarfs with well-known ages are vital to characterize other brown dwarfs, for which ages are in general not known. These spectra are also crucial to test atmospheric models, which have the potential to provide detailed ...
