Characterization of white-light enhancements under umbral conditions in one-dimensional simulations of solar flares

Astronomy & Astrophysics
Context. Solar flares with signatures in the optical continuum (white light, WL) pose a challenge not only to the standard flare model, but also to solar flare simulations. In particular, simulations are so far not able to convincingly reproduce observed

Comparison of three DNA extraction methods for the detection and quantification of GMO in Ecuadorian manufactured food

BMC Research Notes, 2017
Objectives In Ecuador, food products need to be labeled if exceeded 0.9% of transgenic content in whole products. For the detection of genetically modified organisms (GMOs), three DNA extraction methods were tested in 35 food products commercialized in ...

Can Green Energy Finance and Eco‐Friendly Taxes Cap Global Warming to 2 Degrees and 1.5 Degrees Celsius Above Pre‐Industrial Levels? Uncovering the Synergistic Power of Rule of Law

World Affairs, Volume 189, Issue 4, Winter 2026.
ABSTRACT Anchored on the sustainable development goals (SDGs) and the Paris Agreement, which seek to limit the global average temperature to well below 2°C above pre‐industrial levels and pursue efforts to limit the temperature to 1.5°C, this study investigates how green energy finance and environmental taxes affect environmental quality, with an ...

Tracking the impact of bottom trawling on benthic habitat status

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

Chromospheric and photospheric properties of sunspots as inferred from Stokes inversions under magnetohydrostatic and non-local thermodynamic equilibrium

Astronomy & Astrophysics
Context. Sunspots represent a key feature in the solar atmosphere to explore how magnetic fields interact with plasma flows, exhibiting large variations in physical parameters over very small spatial scales (< 100 km), and sometimes featuring dynamic ...

Nonpolar and Polar Lipids Composition in Recombinant Chinese Hamster Ovary Cells by Nile Red Staining Flow Cytometry

European Journal of Lipid Science and Technology, Volume 128, Issue 9, September 2026.
Cellular lipid composition is a dynamic process. Understanding it is important to improve recombinant protein production. Molecules with solvatochromic properties allow the determination of lipids of different polarities by flow cytometry and offer a useful method for monitoring lipids during different phases of cell growth in bioprocesses.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Prospective external validation of ADNEX and RMI for estimating risk of malignancy in adnexal masses in general gynecological settings: Danish multicenter study

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 256-269, August 2026.
ABSTRACT Objectives The primary aims of this study were to validate externally the diagnostic performance of the Assessment of Different NEoplasias in the adneXa (ADNEX) model for distinguishing between malignant and benign adnexal masses, when used by non‐expert ultrasound examiners in general gynecological settings with a low prevalence of ovarian ...
