Article Abstract

A recent perspective defends the approach of the European Food Safety Authority (EFSA) for evaluating the compositional normality of genetically engineered (GE) crops using a concurrently grown subset of non-GE varieties within the risk assessment. While the approach of the EFSA manages the risk of falsely claiming equivalence, this is achieved at the expense of low power to detect true equivalence. This generates inconsistent findings and safety conclusions across studies for the same GE event based on the selected non-GE comparators. Because variation in GE crop composition has not been associated with safety, we suggest policy improvements that would better align with consumer protection.

Hemophilia, an X-linked monogenic disorder, arises from mutations in the or genes, which encode clotting factor VIII (FVIII) or clotting factor IX (FIX), respectively. As a prominent hereditary coagulation disorder, hemophilia is clinically manifested by spontaneous hemorrhagic episodes. Severe cases may progress to complications such as stroke and arthropathy, significantly compromising patients' quality of life.

The growing challenges posed by global warming and the demand for sustainable food and feed resources underscore the need for robust microbial platforms in bioprocessing. Thermotolerant yeasts have emerged as promising candidates due to their ability to thrive at elevated temperatures and other industrially relevant stresses. This review examines the industrial potential of thermotolerant yeasts in the context of climate change, emphasizing how their resilience can lead to more energy-efficient and cost-effective bioprocesses.

Large language models (LLMs) have demonstrated transformative potential for materials discovery in condensed matter systems, but their full utility requires both broader application scenarios and integration with ab initio crystal structure prediction (CSP), density functional theory (DFT) methods and domain knowledge to benefit future inverse material design. Here, we develop an integrated computational framework combining language model-guided materials screening with genetic algorithm (GA) and graph neural network (GNN)-based CSP methods to predict new photovoltaic material. This LLM + CSP + DFT approach successfully identifies a previously overlooked oxide material with unexpected photovoltaic potential.

Wheat blast caused by the fungus (MoT) pathotype is a catastrophic disease that threatens global food security. Lately, was discovered as a blast resistance gene in wheat genotype S615. However, while has recently been cloned, the precise underlying biochemical and molecular mechanism by which this gene confers resistance against MoT, remains to be fully elucidated.
