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

EFSA 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.

A 7 day Multiwavelength Flare Campaign on AU Mic. II. Electron Densities and Kinetic Energies from High-frequency Radio Flares

The Astrophysical Journal
M dwarfs are the most common type of star in the solar neighborhood, and many exhibit frequent and highly energetic flares. To better understand these events across the electromagnetic spectrum, a campaign observed AU Mic (dM1e) over 7 days from the X ...

New Insights into the Large 1992 July 15–17 Flare on AU Microscopii: The First Detection of Posteruptive Energy Release on a Red Dwarf Star

The Astrophysical Journal, 1999
Extreme Ultraviolet Explorer (EUVE) observations of the long-duration 1992 July 15-17 flaring event on the red dwarf star AU Mic are discussed. The flare was detected in the EUVE Deep Survey (DS) Lexan/B band (65-190 A) and was made up of a large impulsive event corresponding to an increase in the extreme ultraviolet (EUV) emission by a factor of 15 ...

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

Arabian 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.

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

Oikos, 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

The 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 ...

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

Journal 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

Molecular 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.

Summertime Carbonaceous Aerosol in Interior Versus Coastal Northern Alaska

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.
Abstract Rapid warming is likely increasing primary production and wildfire occurrence in the Arctic. Projected changes in carbonaceous aerosols during the summer will impact atmospheric chemistry and climate, but our understanding of these processes is limited by sparse observations.
