Today’s links of interest share a science theme. The first two are about twins, and they’re both quite long. I recommend adding them to your favorite long form reader. Next check out NASA’s time lapse compiled from images taken by the Mars Opportunity Rover from January 2004 through April 2015. Finally, read about the science of how we perceive time.

NYTimes: The Mixed-Up Brothers of Bogotá – Two sets of identical twins, mixed up at the hospital and raised as two sets of fraternal twins, are reunited years later.

Could Conjoined Twins Share a Mind? – The New York Times – Krista and Tatiana Hogan are conjoined twins with fused skulls. Bridging their two brains is what a neurosurgeon calls a “thalamic bridge”.

Rover’s-Eye View of Marathon on Mars – YouTube

Road trip! This compilation of images from hazard-avoidance cameras on NASA’s Mars Exploration Rover Opportunity between January 2004 and April 2015 shows the rover’s-eye-view of the Martian marathon covering 26.2 miles(42.2 kilometers) from its landing location. A map of the rover’s path is on the right.

Neuroscience: The man who saw time stand still – BBC

It’s easy to assume that time flows at the same rate for everybody, but experiences like Baker’s show that our continuous stream of consciousness is a fragile illusion, stitched together by the brain’s clever editing. By studying what happens during such extreme events, researchers are revealing how and why the brain plays these temporal tricks – and in some circumstances, they suggest, all of us can experience time warping.
