Scientists put 3D glasses on cuttlefish and showed them film clips. The results were surprising

by Ryan Prior, CNN

Cuttlefish have the ability to watch 3D movies and react to them much like they would if they saw the real thing out in the ocean.

And when it comes to depth perception, they’re incredibly proficient.

Those are the findings from a study published Wednesday in the journal Science Advances.

MIT scientists made a shape-shifting material that morphs into a human face

by Jennifer Ouellette, ARSTechnica

New method based on double-curvature effect described by Gauss nearly 200 years ago.

The next big thing in 3D printing just might be so-called “4D materials” that employ the same manufacturing technique but are designed to deform over time in response to changes in the environment, like humidity and temperature. They’re also sometimes known as active origami or shape-morphing systems. MIT scientists successfully created flat structures that can transform into much more complicated structures than had previously been achieved, including a human face. They published their results last fall in the Proceedings of the National Academy of Sciences.

This Is How The Universe Changes With Every New Year That Passes

by Ethan Siegel, Forbes

With each new year that comes upon us, there are a slew of new events awaiting us not only here on Earth, but throughout the entire observable Universe. Despite all appearances that things don’t change very much, particularly on cosmic scales, our planet, the Solar System, the galaxy, and even the entire Universe all undergo significant metamorphoses that are not only detectable, but that cumulatively add up as time goes on.

All the Ways Facebook Tracks You—and How to Limit It

by David Nield, WIRED

If you have a Facebook account—and even if you don’t—the company is going to collect data about you. But you can at least control how it gets used.

It won’t come as much of a surprise that Facebook tracks you on its platform—that’s why it can resurface your birthday photos from five years ago—but you might not yet realize the scope and the depth of its tracking all across the internet. Facebook’s tentacles stretch out across other websites and services, into the various apps you’re using on your phone, and to the places you physically visit in the real world—especially if you decide to check in on Facebook while you’re there.

Stanford Researchers Miniaturize a Particle Accelerator to Fit on a Silicon Chip

by Stanford University, SciTechDaily

Stanford researchers build a particle accelerator that fits on a chip, miniaturizing a technology that can now find new applications in research and medicine.

Just as engineers once compressed some of the power of room-sized mainframes into desktop PCs, so too have Stanford researchers shown how to pack some of the punch delivered by today’s ginormous particle accelerators onto a tiny silicon chip.
