We present the Quantum Memory Matrix (QMM) hypothesis, which addresses the longstanding Black Hole Information Paradox rooted in the apparent conflict between Quantum Mechanics (QM) and General Relativity (GR). This paradox raises the question of how information is preserved during black hole formation and evaporation, given that Hawking radiation appears to result in information loss, challenging unitarity in quantum mechanics. The QMM hypothesis proposes that space-time itself acts as a dynamic quantum information reservoir, with quantum imprints encoding information about quantum states and interactions directly into the fabric of space-time at the Planck scale.

The risk of developing a severe delayed cutaneous reaction (SCAR) is very low following iodine-based contrast medium (ICM) administration and extremely low following gadolinium-based contrast agent (GBCA) administration. However, SCAR can be very severe and potentially life-threatening. It is crucial for the imaging physician to recognize danger signals: bullous skin eruption, skin erosion and detachment, mucosal involvement, systemic symptoms, and laboratory abnormalities.

Unlabelled: The Châtelperronian and Uluzzian techno-complexes are identified in western Europe in the same stratigraphic position, between the late Middle Palaeolithic and other Upper Palaeolithic assemblages. Both industries include retouched artefacts with abrupt retouch and arched backs, and radiometric dating indicates that these two technocomplexes belong to the same window of time. Here, we provide a detailed, qualitative technological comparison of two Châtelperronian and two Uluzzian lithic assemblages based on a collaborative, first-hand examination of these collections.

Increasing evidence suggests the involvement of metabolic alterations in neurological disorders, including Alzheimer's disease (AD), and highlights the significance of the peripheral metabolome, influenced by genetic factors and modifiable environmental exposures, for brain health. In this study, we examined 1,387 metabolites in plasma samples from 1,082 dementia-free middle-aged participants of the population-based Rotterdam Study. We assessed the relation of metabolites with general cognition (G-factor) and magnetic resonance imaging (MRI) markers using linear regression and estimated the variance of these metabolites explained by genes, gut microbiome, lifestyle factors, common clinical comorbidities, and medication using gradient boosting decision tree analysis.

Iron regulatory protein 2 (IRP2), a post-transcriptional regulator of cellular iron metabolism has been associated with susceptibility to chronic obstructive pulmonary disease (COPD). Resistive breathing (RB) is the hallmark of the pathophysiology of obstructive airway diseases, especially during exacerbations, where increased mechanical stress is imposed on the lung. We have previously shown that RB, through tracheal banding, mimicking severe airway obstruction, induces pulmonary inflammation and injury in previously healthy mice.

In contrast to animal foods, wild plants often require long, multistep processing techniques that involve significant cognitive skills and advanced toolkits to perform. These costs are thought to have hindered how hominins used these foods and delayed their adoption into our diets. Through the analysis of starch grains preserved on basalt anvils and percussors, we demonstrate that a wide variety of plants were processed by Middle Pleistocene hominins at the site of Gesher Benot Ya'aqov in Israel, at least 780,000 y ago.

Human pluripotent stem cells (hPSCs) tend to acquire genetic aberrations upon culture in vitro. Common aberrations are mutations in the tumor suppressor TP53, suspected to confer a growth-advantage to the mutant cells. However, their full impact in the development of malignant features and safety of hPSCs for downstream applications is yet to be elucidated.
