The human eye functions like an exceptionally precise, high-end camera, one with a resolution of around 576 megapixels. What makes it intriguing is that although our eyes can focus on light at only one wavelength at a time, the result isn't fragmented or blurry. What we see feels seamlessly sharp and rich in details. This raises the question of which color it chooses to focus on when the scene we are looking at has multiple colors. A recent study published in Science Advances presents a mechanism that guides the choice. https://medicalxpress.com/news/2026-04-eye-focuses-sharpness.html Tue, 07 Apr 2026 07:50:01 EDT news694752973 For over a century, surgeons performing delicate procedures have relied on stereoscopic microscopes to gain a sense of depth. These tools mimic human vision by presenting slightly different images to each eye, allowing the brain to perceive three-dimensional structures—a crucial aid when working with fragile blood vessels or intricate brain tissue. Despite modern upgrades like digital displays and video capture, today's operating microscopes still depend on the same core principle: two views, interpreted by the human brain. https://medicalxpress.com/news/2025-07-surgical-microscope-tiny-cameras-precise.html Mon, 07 Jul 2025 14:13:03 EDT news671116382 When Brazilian immunologist Helder Nakaya visited Evandro Chagas Institute in Belém (the capital of Pará state, Brazil) in 2017, there was a commotion because one of its best microscopists was retiring and much of the knowledge used for fast and accurate identification of the protozoan Leishmania would be lost. https://medicalxpress.com/news/2022-07-technique-based-artificial-intelligence-chagas.html Thu, 28 Jul 2022 12:37:32 EDT news578230649 If you wanted to design the most perfect, low-energy, light-detecting device for a future camera or a prosthetic retina, you'd reach for something called 'efficient coding theory,' to set out the array of sensors. https://medicalxpress.com/news/2021-09-retina-sensitivity-efficiency.html Tue, 28 Sep 2021 13:14:50 EDT news552053686 A patient who is the first in the UK to receive the world's most advanced 'bionic eye' has been able to read the time for the first time in more than five years. https://medicalxpress.com/news/2016-01-woman-joy-bionic-eye.html Tue, 05 Jan 2016 05:49:57 EST news371195385 Larry Smarr began his scientific career as an astrophysicist studying billions of stars in far-off galaxies.
