Risks for human health related to the presence of plant lectins in food

open access: yesEFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission asked the European Food Safety Authority (EFSA) to assess the risk related to the presence of plant lectins in food. Based on the available evidence, the CONTAM Panel considered only phytohaemagglutinin (PHA), a legume lectin from beans (Phaseolus sp.), for the risk characterisation.

White-Light Continuum in Stellar Flares

open access: yes, 2015
In this talk, we discuss the formation of the near-ultraviolet and optical continuum emission in M dwarf flares through the formation of a dense, heated chromospheric condensation.

Ceramic Production at the Khaybar Walled Oasis During the Mid/Late Third–Early Second Millennium BCE: Evidence for a Burnished Ware Horizon in Northwest Arabia

open access: yesArabian Archaeology and Epigraphy, Volume 36, Issue 1, Page 108-137, November 2025.
ABSTRACT The knowledge of Early and Middle Bronze Age ceramics in Northwest Arabia remains limited, particularly in the Medina region, due to the scarcity of archaeological contexts dated to the fourth–first half of the second millennium BCE. Recent research in the Khaybar oasis has revealed significant Bronze Age occupation.

Radio Emission from the Magnetically Active M Dwarf UV Ceti from 1 to 105 GHz

open access: yesThe Astrophysical Journal
BL and UV Ceti are a nearby (2.7 pc) binary system with similar masses, spectral types, and rapid rotation rates, but very different magnetic activity.

The impact of gigafire on vegetation structure, terrestrial vertebrate abundance and diel activity

open access: yesOikos, Volume 2025, Issue 10, October 2025.
Fire regimes are shifting around the world due to climate and land‐use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood. Particularly lacking is an understanding of how fire affects animal behaviour.

Every Data Point Counts: Stellar Flares as a Case Study of Atmosphere-aided Studies of Transients in the LSST Era

open access: yesThe Astrophysical Journal Supplement Series
Due to their short timescale, stellar flares are a challenging target for the most modern synoptic sky surveys. The upcoming Vera C. Rubin Legacy Survey of Space and Time (LSST), a project designed to collect more data than any precursor survey, is ...

Apache Point Observatory (APO)/SMARTS Flare Star Campaign Observations. I. Blue Wing Asymmetries in Chromospheric Lines during Mid-M-Dwarf Flares from Simultaneous Spectroscopic and Photometric Observation Data

open access: yesThe Astrophysical Journal
We conducted the time-resolved simultaneous optical spectroscopic and photometric observations of mid-M-dwarf flare stars YZ CMi, EV Lac, and AD Leo. Spectroscopic observations were obtained using Apache Point Observatory 3.5 m and Small and Moderate ...

Response of Ionospheric Total Electron Content to the Impulsive and Late Phases of X‐Class Solar Flares With Various Center‐to‐Limb Locations

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract During a solar flare, the fluxes in various lines and continua of the solar spectrum increase, leading to enhanced ionization of the illuminated part of the Earth's ionosphere and an increase in the total electron content (TEC $TEC$). It has been previously shown that nearly 50% of X‐class solar flares exhibit a second peak in warm coronal ...

Leveraging Whole Genomes, Mitochondrial DNA and Haploblocks to Decipher Complex Demographic Histories: An Example From a Broadly Admixed Arctic Fish

open access: yesMolecular Ecology, Volume 34, Issue 10, May 2025.
ABSTRACT The study of phylogeography has transitioned from mitochondrial haplotypes to genome‐wide analyses, borrowing from population genomics methods along the way. Whole‐genome sequencing allows the study of both mitochondrial and nuclear DNA and provides the density of markers to investigate recombination along the genome.

Role of Nonthermal Processes in the Quiescent and Active Millimeter Spectrum of a Young M Dwarf

open access: yesThe Astrophysical Journal
Millimeter (mm) emission from F-M dwarfs (cool stars) primarily traces chromospheric activity, with thermal emission thought to dominate in quiescence. Despite the high chromospheric activity, the quiescent mm spectral fluence (mm- S ( ν )) of young (1 ...
