Electron-photon small-talk could have big impact on quantum computing

Posted by in categories: computing, employment, particle physics, quantum physics

In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a particle of light. The particle of light, or photon, can then act as a messenger to carry the information to other electrons, creating connections that form the circuits of a quantum computer.

The research, published in the journal Science and conducted at Princeton and HRL Laboratories in Malibu, California, represents a more than five-year effort to build a robust capability for an electron to talk to a , said Jason Petta, a Princeton professor of physics.

“Just like in human interactions, to have good communication a number of things need to work out—it helps to speak the same language and so forth,” Petta said. “We are able to bring the energy of the electronic state into resonance with the light particle, so that the two can talk to each other.”

The First Quantum Revolution: Foundational information for the enterprise CTO

Posted by in categories: cybercrime/malcode, quantum physics

Bob Gourley

Our report on Naturally Better Security dove deep into ways quantum effects can be leveraged to enhance real world cybersecurity. It was our most popular post in November 2016 and the feedback we received was taken as a signal that we should produce more on what CTOs should know about the quantum world. With this post we are kicking off a series of five pieces that will dive into quantum effects. This first post tackles some foundational background that puts the science into a historical context. The second one will discuss the current revolution in quantum computing. The third focuses on security concerns. The forth dives into quantum key distribution. The fifth hits on the “so-what” of the current revolution in terms of security.

So first, foundational background on quantum mechanics.

World’s largest hedge fund to replace managers with artificial intelligence

Posted by in categories: finance, robotics/AI, transhumanism

“Bankers will become dinosaurs.” #AI article from The Guardian. https://www.theguardian.com/technology/2016/dec/22/bridgewat…management #Transhumanism


The company is already highly data-driven, with meetings recorded and staff asked to grade each other throughout the day using a ratings system called “dots”. The Systematized Intelligence Lab has built a tool that incorporates these ratings into “Baseball Cards” that show employees’ strengths and weaknesses. Another app, dubbed The Contract, gets staff to set goals they want to achieve and then tracks how effectively they follow through.

These tools are early applications of PriOS, the over-arching management software that Dalio wants to make three-quarters of all management decisions within five years. The kinds of decisions PriOS could make include finding the right staff for particular job openings and ranking opposing perspectives from multiple team members when there’s a disagreement about how to proceed.

Cyrano de Bergerac (1900) — The 1st Movie w/ both Sound & Color — Clement Maurice

And, who said we didn’t have motion pictures with color and sound together before 1931!


Believed to be the first ever, or at least oldest surviving, film produced with both color and sound. The color was made by hand-painting the individual frames of originally black & white film. The sound came from an accompaniment of a sound-on-cylinder recording of Benoit Constant Coquelin’s voice reciting one of Cyrano’s speeches.

Interesting…


It might not work at all, but if the thrust is real and we detect no reaction, could the discrepancy be due to dark matter?

The UN Just Gave Scientists the Green Light to Mess With Natural Selection

Posted by in categories: bioengineering, genetics

Of all the potentially apocalyptic technologies scientists have come up with in recent years, the gene drive is easily one of the most terrifying. A gene drive is a tool that allows scientists to use genetic engineering to override natural selection during reproduction. In theory, scientists could use it to alter the genetic makeup of an entire species—or even wipe that species out. It’s not hard to imagine how a slip-up in the lab could lead to things going very, very wrong.

Young microglia restore amyloid plaque clearance of aged microglia

Posted by in categories: biotech/medical, neuroscience

Rejuvenating the immune system offers hope for Alzheimer’s patients and removal of plaques.


Alzheimer′s disease (AD) is characterized by deposition of amyloid plaques, neurofibrillary tangles, and neuroinflammation. In order to study microglial contribution to amyloid plaque phagocytosis, we developed a novel ex vivo model by co‐culturing organotypic brain slices from up to 20‐month‐old, amyloid‐bearing AD mouse model (APPPS1) and young, neonatal wild‐type (WT) mice. Surprisingly, co‐culturing resulted in proliferation, recruitment, and clustering of old microglial cells around amyloid plaques and clearance of the plaque halo. Depletion of either old or young microglial cells prevented amyloid plaque clearance, indicating a synergistic effect of both populations. Exposing old microglial cells to conditioned media of young microglia or addition of granulocyte‐macrophage colony‐stimulating factor (GM‐CSF) was sufficient to induce microglial proliferation and reduce amyloid plaque size. Our data suggest that microglial dysfunction in AD may be reversible and their phagocytic ability can be modulated to limit amyloid accumulation. This novel ex vivo model provides a valuable system for identification, screening, and testing of compounds aimed to therapeutically reinforce microglial phagocytosis.
