Ottawa researchers develop âbarrel-eliminatingâ optical element 14 Jun 2021 The âspaceplateâ is a new approach to manipulating light that could lead to paper-thin cameras, telescopes, and smart phones. Flatter phones? optics are miniaturized with new counterpart to lens. The concept of âspaceplateâ is a new approach to manipulating light that researchers from the University of Ottawa say could lead to paper-thin cameras, telescopes, significantly lighter high-performance cameras, and âcamera bump-freeâ smart phones. The spaceplate is described as a new optical element, which the scientists say could turn these ideas into reality by dramatically miniaturizing devices, potentially impacting many of the applications in our lives. ....
Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone? In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives. ....

E-Mail Observational studies have suggested that increased vitamin D levels may protect against COVID-19. However, these studies were inconclusive and possibly subject to confounding. A study published in PLOS Medicine by Guillaume Butler-Laporte and Tomoko Nakanishi at McGill University in Quebec, Canada, and colleagues suggests that genetic evidence does not support vitamin D as a protective measure against COVID-19. The ability of vitamin D to protect against severe COVID-19 illness is of great interest to public health experts, but has limited supporting evidence. To assess the relationship between vitamin D levels and COVID-19 susceptibility and severity, researchers conducted a Mendelian randomization study using genetic variants strongly associated with increased vitamin D levels. The authors analyzed genetic variants of 4,134 individuals with COVID-19, and 1,284,876 without COVID-19, from 11 countries to determine whether genetic predisposition for higher vi ....
