Academic clinician–scientists risk becoming an endangered species
Barriers to their training and retention threaten medical research Download PDF Concerns about the future of the clinician–scientist have been expressed for many decades. In 1984, Gordon Gill wrote of ‘the end of the physician scientist’ as he observed academically oriented US doctors move into basic science labs to learn the new techniques of molecular…

‘Unluckiest high-speed rail’: Mother Nature bends human will in infrastructure
According to Chinese media and public data, most of the reasons for suspension of the high-speed railway relate to once-vaunted tunnel projects. The railway crosses the Qilian Mountains on the northeastern edge of the Qinghai-Tibet Plateau. The enormous folds and fault structures formed by crustal movement make the geology in the mountains extremely unstable. Chinese…

Spatial redundancy transformer for self-supervised fluorescence image denoising
Abstract Fluorescence imaging with high signal-to-noise ratios has become the foundation of accurate visualization and analysis of biological phenomena. However, the inevitable noise poses a formidable challenge to imaging sensitivity. Here we provide the spatial redundancy denoising transformer (SRDTrans) to remove noise from fluorescence images in a self-supervised manner. First, a sampling strategy based on…
