Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

Plant, Cell &Environment, Volume 49, Issue 9, Page 7168-7190, September 2026.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

A Non‐Canonical Role of SMAD4 in Regulating 3D Genome Architecture to Inhibit Lung Squamous Cell Carcinoma Development

Advanced Science, Volume 13, Issue 47, 24 August 2026.
SMAD4 is identified as a guardian of 3D genome architecture in lung squamous cell carcinoma. Loss of SMAD4 unleashes EP300 at chromatin loop anchors, strengthening enhancer–promoter looping and H3K27ac at the SOX2 locus to drive aberrant SOX2 activation and tumor cell proliferation.

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, Volume 41, Issue 8, Page 537-548, August 2026.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Blubber Cellular Integrity Through Decomposition and Its Implication for Histological Applications: A Study of Stranded Stock A Humpback Whales (Megaptera novaeangliae)

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Marine mammal strandings can provide unique and valuable insights into individual and population health, ranging from infectious diseases to anthropogenic threats. However, the level of decomposition of carcasses can interfere with the assessment of important indicators, such as an individual's nutritional status.
