A Theory of Consciousness Can Help Build a Theory of Everything

Posted by in categories: neuroscience, particle physics

For an empirical science, physics can be remarkably dismissive of some of our most basic observations. We see objects existing in definite locations, but the wave nature of matter washes that away. We perceive time to flow, but how could it, really? We feel ourselves to be free agents, and that’s just quaint. Physicists like nothing better than to expose our view of the universe as parochial. Which is great. But when asked why our impressions are so off, they mumble some excuse and slip out the side door of the party.

Physicists, in other words, face the same hard problem of consciousness as neuroscientists do: the problem of bridging objective description and subjective experience. To relate fundamental theory to what we actually observe in the world, they must explain what it means “to observe”—to become conscious of. And they tend to be slapdash about it. They divide the world into “system” and “observer,” study the former intensely, and take the latter for granted—or, worse, for a fool.

A purely atomic explanation of behavior may be just that: an explanation of what atoms do. It would say nothing about brains, much less minds.

Quantum Computing Demands a Whole New Kind of Programmer

Posted by in categories: computing, quantum physics

Quantum computers finally seem to be coming of age with promises of “quantum supremacy” by the end of the year. But there’s a problem—very few people know how to work them.

The bold claim of achieving “quantum supremacy” came on the back of Google unveiling a new quantum chip design. The hyperbolic phrase essentially means building a quantum device that can perform a calculation impossible for any conventional computer.

In theory, quantum computers can crush conventional ones at important tasks like factoring large numbers. That’s because unlike normal computers, whose bits can either be represented as 0 or 1, a quantum bit—or “qubit”—can be simultaneously 0 and 1 thanks to a phenomenon known as superposition.

The Scientist Who Discovered a Master Gene to Control Aging

Posted by in categories: biological, genetics, life extension

“Sirtuins are kind of like an orchestra working together to produce a symphony, but each piece, each section, has its own role. Together you get a unified outcome, which we think is improved health.”

— Dr. Leonard Guarente

Dr. Leonard Guarente’s office in the Massachusetts Institute of Technology’s Koch Biology Building is, at first glance, a modest room filled with the artifacts of a decades-long career as a professor and researcher: archives of important journals including Cell, Molecular and Cellular Biology, and Nature; framed covers of his most important papers (he’s published more than 250); achievement awards recognizing his work in genetics and molecular biology; photos of his family; and odds and ends like a dagger presented to him by a student from Thailand and a faded bottle of The Macallan single malt scotch from 1980.

The Mystical Experience

Posted by in categories: biotech/medical, media & arts

“Somewhere something incredible is waiting to be known” — Sagan.


IMPORTANT NEW VIDEO: Mystical experiences induced by psychedelics predict long term positive changes in attitudes, mood, behavior and spirituality in patients. A group of scientists at prestigious research institutions — NYU, Johns Hopkins, MAPS and the Imperial College of London — are conducting studies with psilocybin, MDMA and LSD — which seem to induce mystical-type experiences — to treat end-of-life distress, alcohol and drug addiction, and PTSD. This video explains the nature of The Mystical Experience. Edited by Omid Pakbin music by FluxSeeds / filmed by Jason Goodman, creator of Salt Stage / produced with Ben Jacobson.

Researchers demonstrated violation of Bell’s inequality on frequency-bin entangled photon pairs

Posted by in categories: particle physics, quantum physics

Quantum entanglement, one of the most intriguing features of multi-particle quantum systems, has become a fundamental building block in both quantum information processing and quantum computation. If two particles are entangled, no matter how far away they are separated, quantum mechanics predicts that measurement of one particle leads to instantaneous wave-function collapse of the other particle.

Such “spooky action at a distance” is non-intuitive, and in 1935, Einstein attempted to use entanglement to criticize to suggest that the quantum description of physical reality is incomplete. Einstein believed that no information could travel faster than light, and suggested that there might be some local hidden variable theories that could explain the world in a deterministic way, if and only if they obey realism and locality. In 1964, J. S. Bell showed that the debate can be experimentally resolved by testing an ; by measuring correlations between entangled parties, the result calculated from local hidden variable theories should be constrained by the Bell inequality, which, on the other hand, can be violated in the predictions of quantum mechanics.

By reducing the velocity of light dramatically, researchers at the Hong Kong University of Science and Technology implemented a Bell Test and were able to generate frequency-bin entangled narrowband biphotons from spontaneous four-wave mixing (SFWM) in cold atoms with a double-path configuration, where the phase difference between the two spatial paths can be controlled independently and nonlocally.

First Synthetic Retina Created

Posted by in category: biotech/medical

Until now, all artificial retinal research has used only rigid, hard materials. The new research, by Vanessa Restrepo-Schild, a 24 year old Dphil student and researcher at the Oxford University, Department of Chemistry, is the first to successfully use biological, synthetic tissues, developed in a laboratory environment. The study could revolutionise the bionic implant industry and the development of new, less invasive technologies that more closely resemble human body tissues, helping to treat degenerative eye conditions such as retinitis pigmentosa.

Just as photography depends on camera pixels reacting to light, vision relies on the retina performing the same function. The retina sits at the back of the human eye, and contains protein cells that convert light into electrical signals that travel through the nervous system, triggering a response from the brain, ultimately building a picture of the scene being viewed.

Vanessa Restrepo-Schild led the team in the development of a new synthetic, double layered retina which closely mimics the natural human retinal process. The retina replica consists of soft water droplets (hydrogels) and biological cell membrane proteins. Designed like a camera, the cells act as pixels, detecting and reacting to light to create a grey scale image. The Colombian native said: “The synthetic material can generate electrical signals, which stimulate the neurons at the back of our eye just like the original retina.”

Microsoft will ‘show the world what’s next’ at May 23rd event in Shanghai

Posted by in category: futurism

Microsoft is holding an event this month, the company announced tonight, at which it says it will “show the world what’s next.” The event will take place in Shanghai on May 23rd, but Microsoft didn’t specify either the precise location of the event or exactly what it will be showing. The company did tell The Verge to expect new hardware, however.

There are some additional clues to that new hardware to be gleaned from social media. Panos Panay — Microsoft’s vice president of devices and the creator of the Surface — tweeted the announcement alongside the hashtag “#Surface.” The tag, and Panay’s planned attendance in Shanghai, could mean that Microsoft is ready to show off the Surface Pro 5.

Pirates may have cracked the code to 4K UHD torrents

Posted by in categories: encryption, entertainment

Someone may have finally cracked a form of DVD encryption believed to be impenetrable. Potentially, this could mean it’s now possible to download 4K Blu-Ray movies online, though you shouldn’t get too excited yet.

According to TorrentFreak, an allegedly cracked copy of The Smurfs 2 — why that one, of all films, is a mystery — surfaced on HD Bit Torrent community UltraHDClub. There are no other details at the moment.

We’ve teamed up with Product Hunt to offer you the chance to win an all expense paid trip to TNW Conference 2017!
