Dynamic implications of the biological link between bovine milk and meat production for operationalizing the planetary health diet
Abstract The EAT–Lancet planetary health diet (PHD) provides guidelines on a global scale and calls for red meat consumption to be halved. Operational PHD guidelines at country level have yet to be determined. Here we argue that the biological link between milk and bovine-meat production must be considered when operationalizing the globally calculated PHD to…

Deep contrastive learning of molecular conformation for efficient property prediction
Abstract Data-driven deep learning algorithms provide accurate prediction of high-level quantum-chemical molecular properties. However, their inputs must be constrained to the same quantum-chemical level of geometric relaxation as the training dataset, limiting their flexibility. Adopting alternative cost-effective conformation generative methods introduces domain-shift problems, deteriorating prediction accuracy. Here we propose a deep contrastive learning-based domain-adaptation method…

Establishment and study of a rat internal haemorrhoid model
Abstract To establish a relatively stable internal haemorrhoid model in rats. A total of 48 SPF SD rats were selected and randomly divided into a blank group of 16 and a model group of 32. The model was created by croton oil-mixed liquid stimulation combined with standing and swimming experiments, and the modelling times were…

Critical climate education is crucial for fast and just transformations
If rapid and just transformations to low-carbon societies are to take place, citizens need to obtain the necessary knowledge and skills to critically examine and choose adequate climate policy options. An emphasis on critical climate education research and implementation is therefore required. Climate mitigation is evolving too slowly compared with the pledges and ambitions to…

Stunning stem cells and Starlink trails — November’s best science images
Tasty experiment. Taste tests are conducted under orange lighting at the Wine Science Institute in Villenave-d’Ornon near Bordeaux in southwestern France. The lighting disguises each wine’s colour, so that tasters can be more objective. Here, an employee samples wine from the Bordeaux-producing Château La Tour Carnet estate, which has launched a study into the effects…

Nanofluidic qPCR unable to detect and serotype Streptococcus pneumoniae in urine samples of hospitalized South African patients with community-acquired pneumonia
Abstract Pneumonia is a major cause of death among adults living with HIV in South Africa, but the etiology of many cases remains unknown. This study evaluated the utility of a nanofluidic qPCR assay to detect and serotype Streptococcus pneumoniae in urine samples from patients hospitalized with community-acquired pneumonia (CAP). The nanofluidic qPCR assay was…
