Black Holes are likely sending quantum messages in the universe
Posted by Andreas Matt in categories: cosmology, quantum physics
Spinning black holes are capable of complex quantum information processes encoded in the X-ray photons emitted by the accretion disk.
The black holes sparked the public imagination for almost 100 years now. Their debated presence in the universe has been proven without a doubt by detecting the X-ray radiation coming from the center of the galaxies, a feature of massive black holes. Black holes emit X-ray radiation, light with high energy, due to the extreme gravity in their vicinity. The vast majority if not all of the known black holes were unveiled by detecting the X-ray radiation emitted by the stellar material accreting around black holes.
X-ray photons emitted near rotating black holes not only exposed the existence of these phantom-like astrophysical bodies, but also seem to carry hidden quantum messages.

The Gatekeeper keychain uses bluetooth 4.0 technology with an AES encryption method to automatically lock your computer when you walk away.
Every office has that one coworker—that person who sneaks on to your computer and posts absurd messages on your various social media pages. Fortunately, computers come with handy security features and are generally password protected.

MIT’s 3D-Printed Shape-Shifting Objects Could Revolutionize Medicine
Posted by Shailesh Prasad in categories: 3D printing, biotech/medical, cyborgs
Using light, a team of MIT researchers were able to print 3D structures that “remember” their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures sprang back to their original forms within seconds of being heated to a certain temperature “sweet spot.”
Beyond 3D-printed dinners, additive manufacturing has helped create artificial jaws, better prosthetics, and even brain tumors. Researchers at MIT have found a way to print 3D structures that remember their original shapes within seconds of being heated at a specific temperature “sweet spot,” paving the way towards developing tiny drug capsules that open upon early signs of infection.
Researchers often turn to 3D printing to fabricate shape-memory structures since the technology lets them to custom-design structures with relatively fine detail. The only problem is that conventional 3D printers come with size restrictions—the structures’ details can’t go any smaller than a few millimeters, and the restriction limits how fast the material can recover its original shape.

In a very high magnetic field a ‘massless’ electron can acquire a mass
Posted by Shailesh Prasad in category: particle physics
An international team of researchers have for the first time, discovered that in a very high magnetic field an electron with no mass can acquire a mass. Understanding why elementary particles e.g. electrons, photons, neutrinos have a mass is a fundamental question in Physics and an area of intense debate. This discovery by Prof Stefano Sanvito, Trinity College Dublin and collaborators in Shanghai was published in the prestigious journal Nature Communications this month.

Physicists Force Water Molecules Into a Strange New State of Matter
Posted by Shailesh Prasad in category: quantum physics
Physicists have teased water molecules into a new state—one that has some very peculiar quantum mechanical properties.
For the most part, water on Earth comes in three varieties—solid ice, gaseous vapor, and (everybody’s favorite) liquid form. We’ve all known this since basically forever.
But now physicists, who love throwing monkey-wrenches into things and mucking with our cherished notions of everyday existence, have come up with another doozy—a brand new state of water.

Quick Pro Quo: Software Writes Text 3x Faster Than Any Human Can
Posted by Shailesh Prasad in categories: internet, robotics/AI
Researchers have discovered that voice recognition software Deep Speech 2 has improved to a point that it has become significantly faster and more accurate at producing text on a mobile device than humans are at typing on a keyboard.
Earlier this year, we watched a world-renowned Go mastermind get pummeled in a complex game by an artificial intelligence (AI). Now, humans are about to lose in yet another battle with the machines—and this time, it’s over typing.
