An important breakthrough has been made in the eradication of AIDs. Scientists have found they can successfully snip out the HIV virus from mouse cells using CRISPR/Cas9 technology.

Right now patients with the deadly virus must use a toxic concoction of anti-retroviral medications to suppress the virus from replicating. However, CRISPR/Cas9 can be programmed to chop out any genetic code in the body with scissor-like precision, including, possibly, all HIV-1 DNA within the body. And if you cut out the DNA, you stop the virus from being able to make copies of itself.

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 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.

“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.

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.

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 quantum mechanics 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 inequality; 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.

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.”
