The Application of Carbon Dots in Crops for Sustainable Agriculture

ChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Hunting for Polluted White Dwarfs and Other Treasures with Gaia XP Spectra and Unsupervised Machine Learning

The Astrophysical Journal
White dwarfs (WDs) polluted by exoplanetary material provide the unprecedented opportunity to directly observe the interiors of exoplanets. However, spectroscopic surveys are often limited by brightness constraints, and WDs tend to be very faint, making ...

Thirty-two New Bright ZZ Ceti Stars from TESS: Adding Cycles 4 and 5

The Astrophysical Journal
Analyzing all 120 s and 20 s light curves obtained by the TESS satellite up to Sector 69—the end of the fifth year of observations—for all known white dwarfs and white dwarf candidates up to G = 17.5 mag, we report the discovery of 32 new pulsating DA ...

Corporate Social Responsibility or Strategic Opportunism? Evidence From High and New Technology Firms

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Corporate Social Responsibility (CSR) presents a dual nature in practice. Beyond its explicit ethical imperatives, it can be strategically instrumentalized to manage external pressures, shape public impression, and even divert attention from corporate misconduct. Acknowledging this complexity, this study investigates the conditions under which

Evolution of Cataclysmic Variables with Binary-driven Mass Loss during Nova Eruptions

The Astrophysical Journal
The discrepancies between observations and theoretical predictions of cataclysmic variables (CVs) suggest that there exists unknown angular-momentum-loss mechanism(s) besides magnetic braking and gravitational radiation.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

SN 2022oqm: A Bright and Multipeaked Calcium-rich Transient

The Astrophysical Journal
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multipeaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kpc from its host galaxy, the face-on spiral galaxy NGC 5875.
