Inside the insectary - "These gene drives, they're able to copy themselves. So instead of half of the offspring inheriting the gene drive, almost all of them do. So what happens is that it spreads and it spreads and it spreads. And this is the fantastic thing. Because it allows that gene to be selfish in a population. And in a very short amount of time you can actually transform an entire wild population into a modified population. It's powerful." (previously: 1,2,3)
Nanowire Mesh Monitors Mouse Brains - "Injectable 'neural lace'* brain-computer interface works in mice for months at a time." (via) [more inside]
Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]
The Singular Mind of Terry Tao - "Imagine, he said, that someone awfully clever could construct a machine out of pure water. It would be built not of rods and gears but from a pattern of interacting currents." (via) [more inside]
Frank Wilczek: Physics in 100 Years [pdf] - "Here I indulge in wide-ranging speculations on the shape of physics, and technology closely related to physics, over the next one hundred years. Themes include the many faces of unification, the re-imagining of quantum theory, and new forms of engineering on small, intermediate, and large scales." [more inside]
The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]
Norbert Wiener: The Eccentric Genius Whose Time May Have Finally Come (Again) - "The most direct reason for Wiener's fall to relative obscurity was the breakthrough of a young mathematician and engineer named Claude Shannon." [more inside]
HP scaling memristor and photonic computing: "the device is essentially remembering 1s or 0s depending on which state it is in, multiplying its storage capacity. HP can build these chips with traditional semiconductor equipment and expects to be able to pack unprecedented amounts of memory—enough to store huge databases of pictures, files, and data—into a computer. In theory, that would remove the need for a conventional slow disk/fast memory system. With the Machine's main chips sitting on motherboards right next to the memristors, they can access any needed information almost instantly..." [more inside]
Finite time blowup for an averaged three-dimensional Navier-Stokes equation - "[Terence Tao] has shown that in an alternative abstract universe closely related to the one described by the Navier-Stokes equations, it is possible for a body of fluid to form a sort of computer, which can build a self-replicating fluid robot that, like the Cat in the Hat, keeps transferring its energy to smaller and smaller copies of itself until the fluid 'blows up.' " [1,2,3] (previously)
"The Synth Kit that just hit the market originated a year ago, at a TED conference where Bdeir and comedian/musician Reggie Watts met backstage after giving talks, and started discussing the idea of littleBits musical instruments."
How NASA brought the monstrous F-1 "moon rocket" engine back to life - "The story of young engineers who resurrected an engine nearly twice their age." [more inside]
Reddit interviews Peter Norvig (reddit discussion) related: Seeds of AI at Google -- how the internet is shaping intelligence and learning and, in turn, the role of human culture in natural selection1,2 and why we are not living in western civilization. (via)
The simulated brain - "The scientists behind Blue Brain hope to have a virtual human brain functioning in ten years... Dr. Markram began by collecting detailed information about the rat's NCC, down to the level of genes, proteins, molecules and the electrical signals that connect one neuron to another. These complex relationships were then turned into millions of equations, written in software. He then recorded real-world data -- the strength and path of each electrical signal -- directly from rat brains to test the accuracy of the software." Is it possible to digitally simulate a brain accurately? Can it only be analog? And are there quantum effects to be considered? (previously 1 2 3 4) [more inside]
Andy Grove on Our Electric Future - "Energy independence [viz.] is the wrong goal. Here is a plan Americans can stick to." Perhaps some infrastructure spending1,2 is in order? [etc., &c., cf.] [more inside]
