Computer Scientists Are Working On an ‘Ethical’ Internet

After much research, computer scientists discovered that the real enemy on the internet is humans. The majority of his study is derived from large social media platforms like Google, Facebook, and Twitter. These companies have countless employees who have access to their user’s info. And this confidential information is what’s making these platforms earn billions.

Computer scientist David Magerman has been fixed on this concept and was the first to donate $400,000 to break-up Facebook. After this fruitless quest, he started ‘Different Ventures’ together with well-experienced start-up investors Nick Adams and Alex Katz. They all share interests in astronomical data, and the impact social media has in the world.

Magerman’s focus is to create an exciting and new kind of internet that is secure, easy to use and safe. He’s trying to build a version of the internet that compresses the social media titan to only a percentage of their current worth. He believes that doing so will force these platforms to depend on what they do on their users and not the amount of personal information that they get from them.

I With the use of the ever-reliable 3D printer, scientists have been able to create a liquid magnet. You might be thinking, hasnt science done that already? And youre right, to a certain extent. Scientists did invent ferrofluid, but this new liquid magnet is completely different. Unlike ferrofluid, this brand new invention is able to keep its magnetic properties despite the lack of an independent magnetic field.

II Ferrofluid was invented by Steve Papell from Nasa in 1963. While its pretty amazing, these liquids are categorized as superparamagnets as they cant retain magnetization without an external magnetic field. Inspired by this, scientists from the University of Massachusetts theorized that perhaps there is a way to make these liquids magnetic permanently, all the while retaining their liquid properties.

III What the scientists came up with is a lot like ferrofluid. The magnetic liquid and ferrofluid are both made of ferromagnetic nanoparticles suspended in a liquid base. They also both use iron oxide nanoparticles. The difference is that the scientists used 3D printing that allowed them to combine two liquids to form an elastic film that can hold water.

IV The scientists printed one-millimeter droplets and used those for their nanoparticle suspension. The iron oxide nanoparticles moved toward the surface of the droplets and created a sort of case between them and the oil suspension. This process is called interfacial jamming. In order to magnetize the droplets, the scientists put them near a magnetic coil.

V Through this process, the scientists were able to create permanent liquid magnets. In the absence of a magnetic field, the particles simultaneously rolled towards one another. When exposed to a magnet, the particles tend to align in one direction. The nanoparticles also seem to be able to transfer their magnetic property to other free-floating nanoparticles.

VI The permanent magnetic liquid could also amazingly alter its shape, from a tall cylinder to a flat pancake to a perfect sphere. Surprisingly, it could even change into more complicated shapes such as that of an octopus. Scientists believe that this breakthrough innovation opens a lot of doors, particularly in the fields of robotics and artificial cells.
