Disparities in Vision Testing for Adolescents
Decreased vision testing in primary care and in school settings drove an age-related overall decline in vision testing among adolescents, a review of national data showed. Data from 2018-2019 showed that three-fourths of adolescents had a vision test in some setting within the previous 12 months, though testing decreased with age (1.3% per year of […]
Poor eyesight unfairly mistaken for brain decline
Millions of older people with poor vision are at risk of being misdiagnosed with mild cognitive impairments, according to a new study by the University of South Australia. Cognitive tests that rely on vision-dependent tasks could be skewing results in up to a quarter of people aged over 50 who have undiagnosed visual problems such […]
Fast-melting alpine permafrost may contribute to rising global temperatures
From the ancient sludge of lakebeds in Asia’s Tibetan Plateau, scientists can decipher a vision of Earth’s future. That future, it turns out, will look very similar to the mid-Pliocene warm period — an epoch 3.3 million to 3 million years ago when the average air temperature at mid-latitudes rarely dropped below freezing. It was […]
The abyssal world: Last terra incognita of the Earth surface
The first unified vision of the world ocean biodiversity, based on analysis of DNA sequences from the surface to deep-ocean sediments, unveils the rich and unknown life in the abyssal realm, the last terra incognita of the Earth surface. This collective effort was made possible by 15 international deep-sea expeditions, including scientists from MARUM. The […]
Development of an artificial vision device capable of mimicking human optical illusions: Device may enable image processing without requiring software
NIMS has developed an ionic artificial vision device capable of increasing the edge contrast between the darker and lighter areas of an mage in a manner similar to that of human vision. This first-ever synthetic mimicry of human optical illusions was achieved using ionic migration and interaction within solids. It may be possible to use […]
