Shell Life Post Mass Extinction
One of the biggest crises in Earth history was marked by a revolution in the shellfish – brachiopods, sometimes called ‘lamp shells’ were replaced everywhere ecologically by the bivalves, such as oysters and clams. This happened as a result of the devastating end-Permian mass extinction which reset the evolution of life 250 million years ago.
Will extreme heat eliminate mammals?
A new study shows unprecedented heat is likely to lead to the next mass extinction since the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.

Pocket feature shared by deadly coronaviruses could lead to pan-coronavirus antiviral treatment
Scientists have discovered why some coronaviruses are more likely to cause severe disease, which has remained a mystery, until now. Researchers of the University of Bristol-led study, published in Science Advances today [23 November], say their findings could lead to the development of a pan-coronavirus treatment to defeat all coronaviruses—from the 2002 SARS-CoV outbreak to Omicron, the current variant of SARS-CoV-2, as well as dangerous variants that may emerge in future.
Advanced computer simulations shed intriguing new light on magma deep below Earth’s surface
Advanced computer simulations shed intriguing new light on magma deep below Earth’s surface. Unlike the classic Jules Verne science fiction novel Journey to the Center of the Earth or movie The Core, humans cannot venture into the Earth’s interior beyond a few kilometres of its surface. But thanks to latest advances in computer modelling, an international team of researchers led by the University of Bristol has shed new light on the properties and behaviour of magma found several hundreds of kilometres deep within the Earth.

How vitamins, steroids and potential antivirals might affect SARS-CoV-2
Evidence is emerging that vitamin D – and possibly vitamins K and A – might help combat COVID-19. A new study from the University of Bristol published in the journal of the German Chemical Society Angewandte Chemie has shown how they – and other antiviral drugs – might work. The research indicates that these dietary supplements and compounds could bind to the viral spike protein and so might reduce SARS-CoV-2 infectivity. In contrast, cholesterol may increase infectivity, which could explain why having high cholesterol is considered a risk factor for serious disease.
Research shows emissions of banned ozone-depleting substance are back on the decline

DeepMIP: model intercomparison of early Eocene climatic optimum (EECO) large-scale climate features
We present results from an ensemble of eight climate models, each of which has carried out simulations of the early Eocene climate optimum (EECO, ∼ 50 million years ago). These simulations have been carried out in the framework of the Deep-Time Model Intercomparison Project (DeepMIP; http://www.deepmip.org, last access: 10 January 2021); thus, all models have been configured with the same paleogeographic and vegetation boundary conditions. The results indicate that these non-CO2 boundary conditions contribute between 3 and 5 ∘C to Eocene warmth.
The Trans-Ancestral Genomic Architecture of Glycemic Traits
Glycemic traits are used to diagnose and monitor type 2 diabetes, and cardiometabolic health. To 462 date, most genetic studies of glycemic traits have focused on individuals of European ancestry. Here, 463 we aggregated genome-wide association studies in up to 281,416 individuals without diabetes (30% 464 non-European ancestry) with fasting glucose, 2h-glucose post-challenge, glycated hemoglobin, and 465 fasting insulin data. Trans-ancestry and single-ancestry meta-analyses identified 242 loci (99 novel; 466 P<5x10-8), 80% with no significant evidence of between-ancestry heterogeneity.
Deep Learning for Ultrasonic Crack Characterization in NDE
Machine learning for nondestructive evaluation (NDE) has the potential to bring significant improvements in defect characterization accuracy due to its effectiveness in pattern recognition problems. However, the application of modern machine learning methods to NDE has been obstructed by the scarcity of real defect data to train on. This article demonstrates how an efficient, hybrid finite element (FE) and ray-based simulation can be used to train a convolutional neural network (CNN) to characterize real defects.
A potential interaction between the SARS-CoV-2 spike protein and nicotinic acetylcholine receptors
Changeux et al. recently suggested that the SARS-CoV-2 spike protein may interact with nicotinic acetylcholine receptors (nAChRs) and that such interactions may be involved in pathology and infectivity. This hypothesis is based on the fact that the SARS-CoV-2 spike protein contains a sequence motif similar to known nAChR antagonists. Here, we use molecular simulations of validated atomically detailed structures of nAChRs and of the spike to investigate the possible binding of the Y674-R685 region of the spike to nAChRs.

Discovery of a druggable pocket in the SARS-CoV-2 Spike protein could stop virus in its tracks
A druggable pocket in the SARS-CoV-2 Spike protein that could be used to stop the virus from infecting human cells has been discovered by an international team of scientists led by the University of Bristol. The researchers say their findings, published (21/09/20) in the journal Science, are a potential 'game changer' in defeating the current pandemic and add that small molecule anti-viral drugs developed to target the pocket they discovered could help eliminate COVID-19. This research was supported by Oracle Cloud, BlueCryo, ARCHER and ACRC HPC resources and ACRC Research Software Engineers.

The stability of multitrophic communities under habitat loss
Habitat loss (HL) affects species and their interactions, ultimately altering community dynamics. Yet, a challenge for community ecology is to understand how communities with multiple interaction types—hybrid communities—respond to HL prior to species extinctions. To this end, we develop a model to investigate the response of hybrid terrestrial communities to two types of HL: random and contiguous.
The proportion of missing data should not be used to guide decisions on multiple imputation

Association of Genetic Risk for Rheumatoid Arthritis With Cognitive and Psychiatric Phenotypes
In this cohort study of 7977 children and adolescents, genetic liability for rheumatoid arthritis was associated with lower total, performance, and verbal IQ at age 8 years and symptoms of hyperactivity and inattention from ages 4 to 16 years. However, there was little evidence of association with other domains of psychopathology.
