Can the diffraction limit overcome in the linear imaging system?
1hSpatial-frequency-shift microscopy with evanescent wave illumination shows intriguing advantages, including a large field of view, high speed, and good modularity. However, a missing band in the spatial frequency domain hampers the spatial-frequency-shift superresolution microscopy from achieving resolution better than 3 folds of the Abbe diffraction limit. Recently researchers at Zhejiang Univers

Poor sense of smell may indicate pneumonia risk
2hA poor sense of smell may indicate an older person’s higher risk of pneumonia, research finds. An acute loss of smell is one of the most common symptoms of COVID-19, but for two decades it has been linked to other conditions, such as Parkinson’s disease and dementia. “About a quarter of adults 65 years or older have a poor sense of smell,” says Honglei Chen, a professor in the department of epide
Soaring housing costs are pushing retirees into areas where disaster risks are high
