In 1948, Spanish ophthalmologist Jose Ignacio Barraquer Moner was fed up with glasses. He wanted a solution for blurry vision that fixed the eye itself, without relying on external aids. The surgery he eventually devised was called “keratomileusis,” and his technique focused on reshaping the cornea— what we now know as LASIK. So how does […]

Check out this video by NASA scientist James O’Donoghue showing how fast… or horribly slow, the speed of light actually is.

Getting to space is incredibly hard, expensive and needs a lot of resources. A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space. [Kurzgesagt – In a Nutshell]

Studies suggest that if you made full-body scans part of your regular routine, you’d find a bunch of cancers over the years, but it wouldn’t change your odds of having a life-threatening cancer. This is mostly because our definition of cancer is a little too broad. [SciShow]

You probably think the appendix is a useless organ left over from our evolutionary past, but it turns out it may be doing something important after all. Watch this episode of Scishow to learn all about your appendix! [SciShow]

YouTuber My Microscopic World modified his microscope to harness polarized light, which illuminates tiny creatures in amazing ways. Larva that wear armor shimmer under polarized light as their segments change angle. In other creatures, you can see their internal organs: muscles, eggs, and even what they have recently eaten. Oh yeah, the footage was shot […]

Relative rotation rates and axial tilts of (the only) mapped planets and dwarf planets, at 10hours/sec [OC] from dataisbeautiful An informative animation by data scientist James O’Donaghue showing the rotation speed and axial tilt of the planets of our solar system. I had no idea Jupitrer was spinning that fast considering its size! Wow! [Via […]
