Denis Rebrikov also told Nature that he does not plan to implant gene-edited embryos until he gets regulatory approval.
Maybe interesting.
Few subjects in business and technology are causing as much interest and excitement – or fear and distrust – right now as artificial intelligence. Aalto Leaders’ Insight talked with Teemu Roos, Associate Professor at the Department of Computer Science, University of Helsinki, about a few common myths about AI.

Scientists believe they may have caught a glimpse of a parallel universe bumping up against ours.
They’ve seen hints in signals from the most distant points of the universe that suggest the fabric of our universe has been disrupted by another incredibly different universe. Their analysis may be the proof for the multiverse theory.
According to researchers: “Dr Ranga-Ram Chary examined the noise and residual signals in the cosmic microwave background left over from the Big Bang (pictured) and found a number of scattered bright spots which he believes may be signals of another universe bumping into our own billions of years ago.”
At least that’s the tentative conclusion researchers have come to. According to some cosmological theories, collisions of alternative universes should be possible. Theories conclude that our universe is like a bubble among many.

World renowned Harvard professor and anti-aging expert David Sinclair was recently on the Joe Rogan Podcast. For over 2 hours, he discussed some of the keys to maximizing the human lifespan. We’ve condensed his advice into five things you can do right now to battle the aging process with information that is current, researched, and powerful. So if you’ve interested in learning how to maximize your chances to live longer, take a look at the information below.

Although aging is the greatest risk factor for cancer, a recent study demonstrates how aging cells might, paradoxically, hinder cancer progression.
Are we alone in the universe? It comes down to whether intelligence is a probable outcome of natural selection, or an improbable fluke. By definition, probable events occur frequently, improbable events occur rarely—or once. Our evolutionary history shows that many key adaptations—not just intelligence, but complex animals, complex cells, photosynthesis, and life itself—were unique, one-off events, and therefore highly improbable. Our evolution may have been like winning the lottery … only far less likely.
The universe is astonishingly vast. The Milky Way has more than 100 billion stars, and there are over a trillion galaxies in the visible universe, the tiny fraction of the universe we can see. Even if habitable worlds are rare, their sheer number—there are as many planets as stars, maybe more—suggests lots of life is out there. So where is everyone? This is the Fermi paradox. The universe is large, and old, with time and room for intelligence to evolve, but there’s no evidence of it.
Could intelligence simply be unlikely to evolve? Unfortunately, we can’t study extraterrestrial life to answer this question. But we can study some 4.5 billion years of Earth’s history, looking at where evolution repeats itself, or doesn’t.
A new proposal scheduled to be released from the office of Senator Lee (R-Utah) tomorrow would put the airspace up to 200 feet in altitude over private property under the control of the property owner – and would restrict the FAA’s right to regulate airspace below 200 feet in altitude, making any zoning or regulatory decisions the right of the state or tribal entity governing the land.
DRONELIFE received a summary of the bill from Senator Lee’s office. We may not quote from the summary, as the bill is due to be released tomorrow. In essence, the bill seeks to clarify and control two significant legal issues that remain unresolved: 1) Establish the airspace to 200 feet in altitude above private property as under the exclusive control of the property owner; and 2) Establish state, tribal and local governments as having exclusive and absolute rights to regulate that airspace.
In summary, the bill would propose that the altitude between 200 and 400 feet be designated for the use of civilian drones – although it wouldn’t prohibit the FAA from allowing drones above 400 feet. The area under 200 feet would be under the jurisdiction of state, local and tribal governments – and the bill would call for a redefinition of “navigable airspace” to make that clear.
Contrary to popular belief, cartilage in human joints can repair itself through a process similar to that used by creatures such as salamanders and zebrafish to regenerate limbs, researchers at Duke Health found.
Publishing online Oct. 9 in the journal Science Advances, the researchers identified a mechanism for cartilage repair that appears to be more robust in ankle joints and less so in hips. The finding could potentially lead to treatments for osteoarthritis, the most common joint disorder in the world.
“We believe that an understanding of this ‘salamander-like’ regenerative capacity in humans, and the critically missing components of this regulatory circuit, could provide the foundation for new approaches to repair joint tissues and possibly whole human limbs,” said senior author Virginia Byers Kraus, M.D., Ph.D., a professor in the departments of Medicine, Pathology and Orthopedic Surgery at Duke.
Quantum simulation plays an irreplaceable role in diverse fields, beyond the scope of classical computers. In a recent study, Keren Li and an interdisciplinary research team at the Center for Quantum Computing, Quantum Science and Engineering and the Department of Physics and Astronomy in China, U.S. Germany and Canada. Experimentally simulated spin-network states by simulating quantum spacetime tetrahedra on a four-qubit nuclear magnetic resonance (NMR) quantum simulator. The experimental fidelity was above 95 percent. The research team used the quantum tetrahedra prepared by nuclear magnetic resonance to simulate a two-dimensional (2-D) spinfoam vertex (model) amplitude, and display local dynamics of quantum spacetime. Li et al. measured the geometric properties of the corresponding quantum tetrahedra to simulate their interactions. The experimental work is an initial attempt and a basic module to represent the Feynman diagram vertex in the spinfoam formulation, to study loop quantum gravity (LQG) using quantum information processing. The results are now available on Communication Physics.
Classical computers cannot study large quantum systems despite successful simulations of a variety of physical systems. The systematic constraints of classical computers occurred when the linear growth of quantum system sizes corresponded to the exponential growth of the Hilbert Space, a mathematical foundation of quantum mechanics. Quantum physicists aim to overcome the issue using quantum computers that process information intrinsically or quantum-mechanically to outperform their classical counterparts exponentially. In 1982, Physicist Richard Feynman defined quantum computers as quantum systems that can be controlled to mimic or simulate the behaviour or properties of relatively less accessible quantum systems.
In the present work, Li et al. used nuclear magnetic resonance (NMR) with a high controllable performance on the quantum system to develop simulation methods. The strategy facilitated the presentation of quantum geometries of space and spacetime based on the analogies between nuclear spin states in NMR samples and spin-network states in quantum gravity. Quantum gravity aims to unite the Einstein gravity with quantum mechanics to expand our understanding of gravity to the Planck scale (1.22 × 1019 GeV). At the Planck scale (magnitudes of space, time and energy) Einstein gravity and the continuum of spacetime breakdown can be replaced via quantum spacetime. Research approaches toward understanding quantum spacetimes are presently rooted in spin networks (a graph of lines and nodes to represent the quantum state of space at a certain point in time), which are an important, non-perturbative framework of quantum gravity.
